Originally posted by MSL I've tinkered with Rawtherapee a bit and I think it is the program I want to start using more as I prepare a few images for larger sized printing. However, there are also times when I feel like I haven't got a clue how the program works, or more importantly how I should be working with it. One challenge with the program as a whole is that there is so much to the interface, that simply tinkering with all the options is only partial helpful as you also need to remember where you found each useful option.
So here's idiot question #1:
Let say I open an image, crop it to what I think I want to print then do all my other changes to this contrast, sharpness etc. etc. until I get something I like. But then just before I print, I decide I want to use a somewhat different crop, but still retain all the other changes I made. If I go back in the history and readjust an earlier setting, it erases everything subsequent in the history. So is there a way to tweak something in the history while retaining all subsequent steps. I believe I understand snapshots which allow you to fork off future steps into different directions, although maybe they let you do more things than that. And related to this, say I want to apply a sequence of changes to a second image. Can these steps be saved and applied as a sort of "macro"?
I know there's a few tutorials out there, but if anyone knows of a good one that not only shows you how to do things, but why you might apply certain filters, that too would be helpful to me as I explore.
Thanks.
I've been using RawTherapee for a couple of years now. . . and I think I've just about got it figured out. It's one of those programs where picking up the basics is not as hard as it looks, but really mastering it is more involved than you would even guess.
Strangely, snapshots are not saved between RawTherapee editing sessions, or even when switching between photos during a session. This makes it impossible to use them in most of the ways that you naturally would want to use them. As I understand, making snapshots persistent is something that's been a goal for RawTherapee's developers for a long time, but it never seems to happen. Even more inexplicably, there's another editor which is a fork of RawTherapee, called ART, that does have persistent snapshots!
You might consider finding ART and giving it a spin. I tinkered with it for a while and then went back to RawTherapee, but maybe I just already had learned where the tools were in RawTherapee and didn't want them shuffled around. I might give ART another chance sometime too.
Back to your editing question. . . In the example you gave, I would make the new crop, export the image, then back up in the history to right before the crop, which would effectively restore the older crop value. But again, whether you are using snapshots or simply backing up in the editing history, RT will forget everything if you switch away from that photo!
To apply a set of adjustments to multiple images, you can use the copy-and-paste buttons in the upper-right corner of the window. An ordinary click copies everything you've done to the current image, but a Ctrl-click brings up a panel with a bunch of check boxes where you can check off the adjustments you want to copy and apply. You can also save these adjustment sets to disk as named presets, and load them as needed. The use of presets in RT is worth some study.
As for tutorials, RawTherapee is crying out for an entire book to be written on it.
