Processing Photographs in Rawtherapee

welcome everyone to a first in this series of tutorials on Raw therapy now raw therapy is a RAW processing program it's similar to Lightroom but the thing that makes it great is it is free and open source if you want to download raw therapy you can come here to http raw therapy spelled are aw th er a PE e comm and I know therapy is spelled wrong and you can come to the downloads tab and then you can just click the download arrow for your particular operating system and then install it once installed you can come here and in order to access our images we have to first find them and you can come here to the the folders tab and I'm on a Windows computer so coming here to users and then desktop you can see that I have this image here on the desktop so once this image is selected I can come here to the editor and I can double click on it in order to bring it up in the editor I can also be here in the file browser and just double click if there was more than one image in my folder you would see them display it all up here and you could just double click down the line in order to bring them up here in the image of viewer your interface may look a little bit different than mine perhaps you also have a left sidebar here and you can see that we have this panel right here these panel buttons and these panel buttons open and close the differing panels so I can just click each of them in order to close everything and just view my image or I can open up certain ones as I need given that I don't really need my histogram for now I'm gonna close that and I don't really need this image viewer because I only have one image I'm gonna close both of those to navigate around our main window I can scroll in and scroll out with my mouse wheel or I can zoom in and zoom out hitting the plus or the minus keys on my keyboard right here you can see that I have the hand tool selected I can pan around my image by grabbing that hand tool there are some other tools up here and we'll use some of those for instance this is the straighten or a line tool so I'm going to click on that and you can see immediately as I do over here in the processing profiles area I'm automatically taking over to you the transform tab and now I can just drag a line out in order to straighten my image slightly I'm going to come back here to the exposure tab you may already have a profile added to yours such as brighten or how to match curve ISO something like that what I would encourage you to do is just come down here and click reset and that will reset everything to its default remember raw therapy is about processing RAW images from your camera if you don't know raw image is an uncompressed image file similar to a photograph however a compressed image file would be something like a JPEG image and Roth Arabi can also process those I took this photo with my cell phone and it is current as a dmg you can see up here the name of the image is a dot d ng which is a raw file so to start off with the first thing that I'm going to do is I'm going to come down here to the tone curve and I'm going to click here and select standard and you can see the histogram of my image and in order to add contrast to my image I'm going to take this point here on my graph and I'm just gonna drag it over until I am at the beginning of where you can see the mountains of my histogram and if I want to I can turn on the clipped button to see where where items in my scene are a hundred percent black I don't want too much if I bring this all the way over you can see that there's too much black and that's not going to work well for me so I'm going to just bring that back to the very beginning and now I'm going to come to this this white triangle and I'll clip that I'll I'll select that and that shows me where things are 100% white so what I'm doing here is I'm selecting my lack and white levels and you can see that if I move this all the way over everything that's black is that a hundred percent white in my image so I'm just gonna go ahead and find I'd like to come down here to the bottom so I can kind of see what I'm doing and select about an area and then bring it up to the top and you can see that my clouds are blown out there but that's image in the background that's information in the background it's not super relevant okay so now if I want to I can come back up here and adjust my exposure accordingly and you can see that if I adjust it like this everything it's wider or if I come back here everything gets darker I'm actually gonna darken it down just a little bit because I don't want to lose the detail in the sky next I'm gonna come here and I'm gonna take the saturation and bump it up a little bit mm-hmm say a saturation value of 40 seems about right now I'll close that down and come over here to the graduated filter you can see as I turn that on all of a sudden this top half of our image has gotten darker and the reason for this is because the graduated filter if I click this button darkens things out so if I have it down here at the bottom or here at the top what I'm actually gonna do is I'm gonna go ahead and rotate this around and place it right here and then I can you can see I can either make it lighter or darker and I've actually rotated it the wrong way if I rotated it back around like this and then I can go ahead and pull the strength backwards I can actually lighten up this part of my image of course I have to be careful because places like this will get blown out so I don't want to do this too much and I can actually turn it off to see the effect that it's having and I just want that to be a subtle effect and if I feel like the effect is too is not gradual enough I can actually increase the feather you can see that the distance between these two these two lines increases indicating that there will be a greater and more gradual transition between the dark and the light okay next we'll come here to the tone mapping and we'll just go ahead and turn that on and that will just brighten everything up I'm just gonna rotate this slightly and then decrease the strength in order to lighten that up just to just a hair more so we can turn the tone mapping off you can see that the tone mapping also adds a little bit of sharpening and speaking of sharpening we can come over here to our detail tab and we can turn on the sharpening right here our detail tab is also where we can do things like noise reduction or D fringing we can also do haze removal if I turn that on you can see that it removes lots of the haze and adds a lot more saturation to my image so I like where this has gone so far next I'm going to come here to the color tab and if I wanted to mess with the white balance I could here in the white balance tab but also I want to add some vibrance so I'll turn the vibrance on by ticking the on button there and then I'll just increase that until I feel like the colors are as vibrant as I want them to be perfect now that that's done I'm going to come here to the transform tab and turn on the crop tool I'm gonna crop this image for Instagram so the ratio that I will use is a 4 by 5 ratio and then in order to move my box around I'm going to hold shift and drag I can resize it by grabbing one of the sides and either pulling in or out and I'll resize it as such if I want to select my area I can choose select and if I want to freely crop I can go ahead and uncheck lock ratio I can also select portrait or landscape so that this will turn 90 degrees and my long side will be across my image one important thing to note in RAW therapy is that when you crop your image it leaves the pixels here just in case you want to uncropped it later if you don't want to see those you can just come here and change the background color to black the lighter gray or a white but I'm gonna go ahead and leave it on the D for now next I'm going to come here to resize and I'll turn that on and what I want to do is go ahead and resize where it says the height and I'll just put in 4k just because I want my final JPEG image to be nice and compressed okay there we go now I'm going to bring back my top view here and I can right-click on this and I can say put to cue and if I put that to cue what that will do is it will add any image that I click that the cogwheels on will come into the queue and then I can take all of my cue and I can just turn it on and it will process all of those images at once but if you just want to process one image you don't have to go through that whole process you can just hit control s I want to save it here to my desktop I'll change the output to a JPEG and I'll give it a name such as flowers if you want to save the processing parameters in a separate file you can go ahead and take this and then I can just click OK and you can see I've opened up our image and it looks great as I'm looking at the finished JPEG however I'm noticing that it's quite Boise so let's go ahead and fix that I'll come back here to raw therapy and come to the sharpening or the detail tab and here in noise reduction I'll turn it on now you can see many of these have a one to one ratio what that means is you won't be able to see oops not impulse noise reduction noise reduction you won't be able to see the effects of that particular tab unless you are at a one-to-one ratio of zoom on the an easy way to do that is come down here and click this this one to one zoom now I can turn off the the noise reduction you can see it's quite noisy I can turn it on and then I can add a little bit of luminance you can see if I add a lot of luminance it smooths everything out but I get artifacting here around edges so I'll add maybe about 20 in the luminance and then for the detail recovery I'll bring that up to maybe 5 now as i zoom around my image I'll just make sure it looks okay if i zoom back out to 100% or to my crop by hitting this button I can no longer see the effects of the noise reduction save it one more time and you can see it saved a separate file flowers - one I'll double click and you can see that our noise issue has now been taken care of thank you so much for watching I hope that this has been super helpful for you if it has consider adding a like or a subscribe and please consider commenting about your images below thank you so much and I'll see you next time [Music]
