[Music] [Music] hello and welcome to yet another tutorial by Davies media design my name is Michael Davies and in today's tutorial I'll be showing you how to add graphics to complex perspectives using this is conversion to point ten point eighteen which at the time of this tutorial is the latest version of but of course before I get into that I want to direct you guys over to my website at Davies media design.com as always I have tons of and Inkscape tutorials on here as well as my book of layers and and Inkscape help articles so definitely check that out you can roll in my 2.10 masterclass from beginner to pro photo editing on you to me you can enroll in any my skill share classes by visiting school comm and you can get more with a premium membership to davies media design your premium membership includes access to my Help Center app ebooks such as my book of layers and exclusive content not found on YouTube you could start your subscription with a 7 day free trial and I'll include a link to this as well as all the relevant links from this tutorial in the description of the video so I'll be using a couple of free photos today so this one is from pixels you can download this for free by clicking the free download button and another one from pixabay this is a photo of some patterns here again click the free download here is the final result of the tutorial so I've taken the pattern and I've put it here on the stairs so it looks like it's painted on the stairs it also has some texture going on and it looks like the girl is sitting on the graphic and you can see the graphic isn't just flatly placed across the stairs it goes along with the stairs in perspective this is a fairly complicated tutorial but I won't break it down in a way that beginners can follow and understand you also will need 2.10 point 18 to be able to accomplish this tutorial to complete this tutorial because there are tools I'll be using that are only found in to point 10 point 18 or newer alright so let's get started I'll start by opening up the original photo so go to file open recent and here is my photo I'm going to hit convert to convert this to giimpse native sRGB color space and I'll hold ctrl and zoom out you guys can of course locate your image on your computer by going to file open so the first problem we need to solve is we need to establish the vanishing point the vanishing point in terms of 3d is going to be the point at which all the lines are converging together in your and so when establishing that vanishing point it's going to allow us to base everything that's going to have a 3d perspective off of that vanishing point I'm not going to get too deep into that because I'm not a huge expert in 3d concepts but that's the basics of it so in order to establish a vanishing point we need to find some lines in the photo which this one does have a lot of lines and just follow those lines and see where they go exactly so the easiest way to do that is to create a new layer and I'll name this vp4 vanishing point fill this with transparency and click OK then I'll come over and grab my paintbrush tool and I'm gonna switch to a color that's easy to see so I'm gonna switch to this blue color you guys can switch to whatever color you want and I'll click OK I'm gonna decrease the size of my brush because I don't need a huge brush for this it's a pretty small brush then what I'll do is I'm going to click on or near one of these lines that you can see so in this case I'm gonna use the brick wall you guys can use whatever lines you have in your photo then I'll hold the shift key to enter straight line mode and I'm just going to draw this line pretty much across my entire photo like so so you can see this is the first line that's helping us establish a vanishing point of course we can't do this with one line alone we need to do this with multiple lines and what we need to do is figure out where our various lines are intersecting so I'll come down here this line you'll see is going upwards so I'm going to click on here hold the shift key and I'm going to just follow that line as closely as I can and click so you can see right now already these lines are intersecting so that's telling us that essentially as it stands our vanishing points should be around this point I'll do a couple other lines just to make sure so come up here hold the shift key and I'm going to click and you'll see that line also converges there let's come up here so here we have another line and I'll click so that one is also right here so what I like to do is just circle that and that's going to tell me that that is my vanishing point right there and I'll be referencing this point throughout the tutorial so next up I'm going to draw a perspective box or a rectangle that's going to help me determine in what general area I need to place my graphic in and that way we can keep the graphic relatively within the correct perspective so to do that I'll start by opening my pattern so go to file in my case open recent for you guys just go to file open and here is my original pattern I actually changed the color of this I'll do that later in the tutorial you do want to open this as a new composition and next I'm going to click and drag the tab of this composition over let's go to this one that we're working on not the final one and I'll release so here you can see my pattern is a pretty good size if your pattern is too large make sure you scale it down with the scale tool until it's a pretty small size so in this case I'll hit the M key to grab my move tool I do want this to be a little bit thinner than the width of the entire staircase here that way we have some wiggle room so I like that this is a little bit smaller so I'll keep that there next I'll come over and create a new layer and I'm going to name this layer perspective rectangle make sure it's filled with transparency click OK now I will alt click on my dropped buffer layer which is my pattern layer and then I'll make sure I'm still clicked on my perspective rectangle layer hit shift B on the keyboard and let me just switch over to a white foreground color I'll fill this in with white control shift a to deselect that then come over to layer crop to content that will crop everything down to the size of that rectangle we can remove the drop buffer layer now we don't need that just yet so I'll come back up to the perspective rectangle layer next I'll come over and grab my tool this is going to be the 3d transform tool so click and hold if you have your tools grouped and it's gonna be inside of the transform group and you can also hit shift W on your keyboard so this tool is only available in 2.10 point 18 or newer it was just added so if you don't have that version you're gonna have to upgrade to that latest version of course it's totally free and now I'm going to click on this perspective rectangle layer right now my image opacity for the preview over in my tool options is set to 100 I'm gonna turn that down a little bit that way I could see what's going on behind it next I'll come up here to the 3d transform dialog box and click on camera and the very top tab which is camera is going to contain the vanishing point so keeping this set to fov which if i click on it you'll see is field of view we're going to grab this little circle and we're going to click and drag it until we reach that vanishing point we established earlier so now that's a line there that's going to ensure that as we change the perspective as we move the rectangle around it sticks in the same perspective as the overall image that's what makes it look more realistic so now I'll come over here and I'll click on the rotate option and I'm going to change this so that it rotates from the top this is already aligned at the top of my staircase so it doesn't need to move anywhere from that position now what I can do is just click and drag this x value the X angle and I'm just going to drag this until it matches with the stairs like so so you can see it's matching because it's basically touching the tip of each point of the stairs here it's not exact but it doesn't need to be exact and that's all we need to do for this portion so now I'll hit transform by the way if your rectangle was not aligned with the top of the stairs just use the move tool first before you grab the 3d transform tool and then do all those steps I just talked about with the 3d transform tool alright so now I'm going to turn down the opacity of this quite a bit and now we have a general idea of where we want our graphic to be it's going to be inside this boundary here so if this is too small in terms of how you want it or the boundary isn't centered where you want it I do recommend moving this around with the move tool until it's positioned where you want but this is the general area where I want my graphic so I'll keep it here next I'm going to mark out the steps that we have because each one of these steps is basically going to be its own perspective so what I'll do is come over and create a new layer and I'll name this steps and hit the enter key so if you're using a diff type of image this is essentially just marking out the planes that 3d planes or even in this case sort of the 2d planes where you're going to be placing graphics so you'll see what I mean so on the steps layer I'll hold ctrl and zoom in and grab my rectangle select tool and I'm going to make sure this is set to add to the current selection let me actually zoom out a little bit you'll notice you can see the top of the stairs here but you can't see them here that's because the vanishing point is below these stairs so you can't see any of those planes up top there but you can see them below here on the stairs so what that means in this step is that when I'm using my rectangle select tool I'm going to click and drag and I can select all of these that I can't see this plane for example all of these steps where I can't see the top I'll select all those simultaneously just to save me some time and I'm going to stop this right at the bottom of that last stair and I'll make sure that this rectangle goes outside the perspective rectangle I drew so now you'll see all this area is selected so now I'm going to skip this little area this little plane because it's on a different perspective and I'll jump over here to this lower one this next 90 degree angle stair here and I can always adjust this like so I want this to be as close as possible it doesn't have to be perfect I want this to be as close as possible and then I'll do this step low like so again trying to match this up as close as possible and you'll notice I skipped this plane right here all right so now we have these different areas marking the flat portions here next what I'll do is hit shift B to grab my bucket fill tool and I still have white as my foreground color so I'll fill this in with white and I'll just decrease the opacity that way this blends a little better and now I'll add both of these layers to a layer group so I'll create a new layer group double click and name this steps element hit the enter key and then click and drag both of these inside of this layer group so now I'm going to all click on this perspective rectangle layer and then I'll hit ctrl I and that's going to select the invert of that perspective rectangle layer now I'll click on that steps layer and I'm going to hit the Delete key and that will delete all of that excess so I'll hit ctrl shift a to deselect that and now we have a rough template or a rough outline of how we're going to create our perspective I know this is looking a little primitive right now but it's going to improve as we get through this tutorial next I'm going to come over to my graphic layer my pattern layer and I mentioned I change the color of this so I do want to do that again I'll come over to colors hue/saturation and clicking on the master I came over here and I just drag the hue around until I found some colors that I preferred and I also came over to the red Channel if I remember correctly and just crank that all the way up you guys can also play around with some of the other settings like the lightness etc and I'll click OK so once you have the colors the way you want come back over here to your photo and you need to count the number of areas that you need to cover so in this case we're going to count each time there's a perspective and let me actually just hide the steps element layer group so we have this first one here that's 1 the second plane that we need to recognize is actually not visible because it is above the vanishing point so we're counting both visible and invisible planes so we've got 1 2 3 4 the top of this step here 5 6 the top of this step 7 8 the top of this step which we can actually see 9 and then is the top of this step I'm not going to do the last step so again there are ten different surfaces here that we're going to be working with the reason we want to know that is that we're going to divide up our pattern image into ten equal slices and we're going to take these slices and then place them into our image in the proper perspective so I'll come over here and I'm just going to demonstrate with a couple of guides because I've already done this but what you need to do is go to image guides new guide by a percent and in my case I know that I'm dividing this into ten of course one divided by ten is ten percent so my first guy that I'll place at ten percent and the direction will be horizontal and I'll click okay so there's the first one the second guide I'll go to image guides new guide by a percent and this time I'm going to add ten percent again so I'll do 20 so as I go down here it would be 20 30 40 50 60 70 80 and then 90 percent will be the last one and this will be the final result over here so this is the first time I did this once you've divided this up equally into ten different slices what you'll do is come over to image slice using guides so now our path image has been divided up into ten different compositions the top is going to be over here on the far left the bottom will be on the far right so what I'll do is I'll hit ctrl C to copy this and then I'll come over to our composition and hit ctrl V to paste it and I'll place this floating selection on a new layer and then I'm going to click and drag that new layer outside the layer group so here is our first pattern I'll need to unhide the steps element here the layer group and I'll hit em on my keyboard to grab the move tool and move this towards the top hold ctrl and zoom in and I can adjust the opacity of the steps element layer group so let me just turn that down a little bit and using move to let me move this out of the way for a second so what I need to do is figure out where I need to place this so I'm gonna grab a guide and place it at the top of the stairs move this out of the way grab a guy to place it at the bottom of this first step right there next I'm going to grab a guide and place it at the top corner of the image and then I'll grab another guide and I'll place it here where the step ends so you can see the wall is right there so this is the area where I want my first slice to be placed so now what I'll do is come over here click and hold and I'm going to change this to the perspective tool you'll see the shortcut key for that is shift P and now I'll come over and make sure I'm on my first pattern layer and I'm going to click on that with the perspective tool I have the image opacity for the preview turn pretty far down so I can grab the middle part to move this and I can grab the corners and these should snap to your guides if not go to view snap to guides so now we can just move this into place until it snaps to the guys there that looks pretty good so I'll hit transform and there is our first shape the second shape we're also going to need to play some guide so I'll place a guide at the bottom of that step I'll place another guide at the far right of this step and then I'm gonna hold ctrl and zoom in I'm gonna place this guide here right where the guide of top intersects with this perspective rectangle and by the way the top I did was a bit too high so it's not gonna be quite as accurate this time around but I'm still going to reference this perspective rectangle as I get through this tutorial so here's the weird part the second piece of this pattern is actually not visible just because of how 3d works so the vanishing point is below the point of this step so you can't see the top of it so the reason I mentioned that is that this was the first slice the second slice will not be visible so we're just gonna skip right to the third slice so here's the first slice the second slice and here's the third slice so I'll hit ctrl C come back over here control V place this on a brand new layer the floating selection hit M to grab my move tool and just move this relatively into place and now I'll grab my perspective tool again and click on this and I'm just gonna drag this until it snaps here and you guys might be wondering why am i using the perspective tool and not the 3d transform tool the reason is that because of the way these stairs are because they're just a flat plane right now they're not really 3d necessarily it's just 2d with a little bit of tweak to the perspective once we get to those planes that are more on a 3d plane that's what we're gonna use the 3d transform tool so I have this one in place I'll hit transform there is the placement of our third slice remember the second one is not visible so that's the third the fourth slice is also not visible so we're gonna go to the fifth slice now so one two three four here's five ctrl C to copy that come back here control V add this to a new layer so our floating selections on a new layer I'll hit the M key to grab my move tool move this down a little bit and now I want to drag my guides into place once more so I'll drag this down here until we get to the end of the step then I'll drag a vertical guide until it meets with this portion here where our guide above intersects with the perspective rectangle and then I'll come over here and drag a guide until it matches up here with this step and we might have to reposition this guide maybe like that the steps may be uneven in some parts that's alright I'm going to show you guys how to sort of deal with that later all right so we're on the pattern layer and so now I'll grab the perspective tool click on this and then just click and drag this until it snaps to the guides hit transform and there we have yet another pattern placed so the one below is the last one before we get to the 3d plane so I'll click and drag a guide place it right here grab another guide place it where the perspective rectangle intersects there with the last guy we made and then over here with the last portion of the step before it hits the wall hold ctrl and zoom in you can always grab the move tool by hitting M on your keyboard and reposition this hold ctrl zoom out hold ctrl zoom in just double-check this all right so we went one two invisible three four invisible five six invisible now we're up to seven so we'll go one two three four five six seven control C to copy that come over to the composition ctrl V to paste we're gonna place this on a new layer with the move tool we can drag this down shift P to grab your perspective tool and once again we'll just drag this until it snaps to the guides now come over hit transform alright so next up is our first 3d plane so what I'll do is once again place a guide approximately where I want this to end and that's the only guy at all place for now so that was the seventh slice now we need the eighth slice so 1 2 3 4 5 6 7 8 ctrl C to copy that come back over here to our image ctrl V to paste put this floating selection on a new layer hit the M key grab the move tool move this down a little bit I'll move this until it snaps to that guide there now what I'll do is click and hold this and grab the 3d transform tool or hit shift W and I'll click on this once the first thing I need to do is make my vanishing point visible so let me drag that layer to the very top so there's that vanishing point let me actually just regrab the 3d transform tool so come back over here to my pattern we were working on click on it with the 3d transform tool now we can see the vanishing point so I'll come up to the camera and here's our little vanishing point perspective here I'll drag that until it reaches the vanishing point we set up again at the beginning of the tutorial then I'll come over and grab the rotate option and I'm going to click and drag the slider and let me actually ctrl Z to undo that I can click the top here again and drag this out so that's changing that perspective we can come over here and use this line here to determine how much we need to rotate the X so once these two match up pretty good we'll know we're where we need to be so that's pretty good for now obviously it's hard to tell how accurate that is because what we need to do now is come over here to the move option and I'm just going to decrease the Z value that's going to increase the size and what I'm looking to do is decrease the Z value until this corner matches up with this guide here and this corner matches up with this guide because essentially the far ends of this need to match up with the last pattern that we placed so I'm just going to keep increasing it until it gets pretty close once it's closer I can use the X value to ship this to the left or the right so you can see by shifting this left currently this is a little too large so I can decrease the size of it by making it more of a positive value and then use the Y offset here to shift this over that's pretty close so now I can use Y to either shift it up or down and everything's kind of opposite here so it gets a little confusing sometimes so that is approximately in place but you can see it doesn't quite line up so what I need to do is come back over here to the angle and just readjust this so you can see I'm pointing the nose of this down a little bit by decreasing the value of X and there you can see it's lining up pretty good so come back over here we might be able to move this up a smidge hold ctrl and zoom in you can see how close you are there if you want to get very accurate with this you can also adjust other parts of the angle so not just the X you can do y&z as well so for example if I came over here middle clicked on my mouse that allows me to select this let's say I typed in point 2 and I'll do a negative sign so negative point 2 for the Y if I hit enter you'll see that I'll just shift this ever so slightly and let me also try that with the Z so point 2 negative hit the enter key so that's actually the opposite way I want to go so let me erase the negative hit the enter key you can see that shift that slightly I'll go a point 1 enter so that's pretty close so now hit transform so there is our first step there with the 3d transform now I need to do the step below so that's going to be our ninth pattern so I'll come over here to number 9 ctrl C come back over here control V paste this floating selection on its own layer we can hide the vanishing point for now we don't need it for this layer hit the M key to grab my move tool and drag this down now I need to grab my guides so I'm going to drag a guide to the bottom of these stairs drag this guide to the point where this portion here this corner intersected or almost intersected with with the rectangle hit the M key to grab my move tool and then we need to place a guy here as well so this one I'm going to place instead of it being at where the stair ends I'll place it wherever the corner of this ended make sure this corner didn't go past the stairs otherwise it won't look realistic so now I'll hit shift P to grab my perspective tool and now I can drag this into place so that looks pretty good I'll hit transform you guys might be asking why not use the perspective tool the whole time for each portion of this the reason is that the perspective tool doesn't really create the correct 3d plane that it needs to because it doesn't have a vanishing point option so the graphics end up being a little bit off when you just use purely the perspective tool throughout this thing so that's why I'm alternating between the two tools so now we're on to the last plane here the last portion so I'll grab the tenth pattern ctrl C to copy that come back over here ctrl V to paste put this floating selection on a layer and hit M on my keyboard to grab the move tool move this down until it snaps to that guide and let's drag some guides over so here's the bottom of the stairs it probably won't go that far but it might alright once we've placed the guide at the bottom of the stairs now I'll hit shift W to grab that 3d transform tool and of course the first thing I need to do is grab my camera turn on the vanishing point layer and I'm just going to drag this to set the vanishing point then I'll come over to the angle or the rotate option and once again I'll click to snap this to the top so it's rotating from the top of the layer and then I'll drag the X until it's approximately where I need it to be so about right there come over to the move option with the offset option and now I'm just going to decrease the Z value to increase the size of this if it starts to disappear on you you can just use the Y value to move it back in place same with the x value so once again we're trying to match up the corners here with the corners of the top pattern layer or in other words the guides that we have so now I'm going to decrease the Z value to move it out some more shift the x value to move it left or right right now it's a bit too large so turn it down shift it and then we can move it up with the Y tool so this one's actually fairly close we can of course tweak the x-value if it's a little off like that hold ctrl and zoom in so there's a bit of a gap there so I'm just going to switch over here to the offset and just move that up and we can always do this in an increment so maybe 180 3.5 hold ctrl and zoom out hit transform and there we have our final graphic of course this looks pretty messy right now so let's clean it up we could start by hiding the vanishing point layer hide these steps element layer and then come over to image guides remove all guides that will delete all your guides so make sure you don't need those for anything all right so there's the pattern in the shape of the steps but now we need to blend this with the textures of the steps so it looks more realistic so first I'm going to place all of these graphics into a single layer group and then we're going to use what I taught in the last tutorial and that is the color to alpha filter so I'll come over create a new layer group and I'll just name this pattern design hit the enter key and now I'll just click and drag these making sure they're in the same order drag them each into the layer group all right so now all those layers are in the layer group so I can collapse that that helps clean that up now I'll click and drag this below the original photo layer and first before I do anything I want to edit this slightly so I'll just come over to colors levels and I just want to brighten this photo up click okay then I'll duplicate this and I'm gonna hide the duplicate come back over here to the original right click and make sure this has an alpha channel so click add alpha Channel then I'm going to alt click on the layer below so that selects our patterns and with that selected and with the original layer still active the image layer I'll now come over to colors color to alpha and you can either leave this at white you can click on this and make it a darker color like that or you can grab the color picker and use a color from the photo itself whatever you prefer to do I'll just leave it like that and click OK you can adjust the opacity threshold if you want to make this slightly less opaque and that helps some of the textures come through from the image if it's too transparent you can bring up the transparency threshold slider as I mentioned I just did a tutorial on this a couple days ago so I'll link that to this video so you can check it out once you have the settings the way you want them click OK and hit ctrl shift a to deselect that so now the issue is you could see some of the patterns on her hand so to get rid of that what I'll do is unhide that copy we created click on that layer and let me just rename this copy at the enter key now I'll right-click on this and go to add layer mask and I'll choose black full transparency and click Add now with the layer mask still selected I'll come over and grab a paintbrush tool you know increase the size of the paintbrush and I also have this set to a pretty soft brush hold ctrl and zoom in and my color is set to white now I can paint white on any of these areas where I want to remove the pattern and for the sake of time I'm just using a big brush right now you guys can use a smaller brush and spend some more time on the details and because of the color I selected with the color to alpha there's not a whole lot of detail coming through right here but you guys can change the color on the color to alpha to fix that I'm just going to make sure that all this is cleaned up so once that's cleaned up you can increase the size of your brush and what I want to do now is make these edges look rougher because right now they're kind of you know too perfect and it looks fake so I'll just slightly brush up with the larger brush against the edges and that's making those edges look slightly more faded of course I don't want to overdo it can also do the bottom here one last finishing touch I can put on this image is I can add some blur to it to make it look more realistic like it has the same blur as the lens that was used in the original photograph so what I'll do for that is come over here and I'm just going to duplicate the pattern design layer group and then I'll shift click on the merge down icon that'll merge everything from the layer group onto a single layer and then come over to filters blur Gaussian blur and turn the blower up slightly maybe to about right there click OK next I'll right-click go to add layer mask and we'll choose black full transparency and click add now I'll come over and click and hold on the bucket fill tool and grab the gradient tool then I'll click and drag this gradient and make sure the shape is set to linear and you have the color set to foreground and background RGB and you can see that as this goes from black in the lower left corner to white in the upper right corner it's revealing some of the blur up top here and that's making this travel as if it is the lens blur so it's sharper down here more blurry up here and that matches the depth of field from the original photo so hit enter and there is our final result all right so that's it for this tutorial hopefully you liked it if you did you could check out my youtube channel
