I was wondering if there is an easy way in RT how to obtain the best spot for white balance. Sometimes I find a picture problematic and in order to find the best spot for WB I must spent just too much time on looking for it (which is an area that has similar or close all the RGB values)
In gimp/photoshop it gets easier because I can create a new, blank layer, fill it with middle gray, set its blending mode to ‘difference’ and use threshold to obtain it (see: https://patdavid.net/2011/06/getting-around-in-gimp-color-correction.html).
Is that technique possible in RT? I know that 'retinex” has some masking capabilities, but it is complicated tool. I’m currently experimenting with it and wavelets – but with no luck.
If it is not possible, would it be difficult to implement such a nice feature? It would be really helpful and save rt users a great deal of time.
Another idea would be to set a white balance according to skin tones. Alex from magic lantern project implemented it once in ufraw (https://www.magiclantern.fm/forum/index.php?topic=9469.0)
Also, i’m crossing my fingers for @jdc and his WB ‘robust’ research and work.
Although I have Photoshop and Lightroom, I keep coming back to my favorite duo – rt + gimp!
