I like to restore bad faded images with (strong) color cast. So then Iains “RGB tone” and “CMYK tone” are great. The filters are like the channel-mixer, but more sofisticated. So they are great for color correcting underwater-images also.
All “Mixers [colorspace]” are useful. I like the new “Mixer [PCA]”. This last mixer is also useful for showing faded cave-drawings. Because you can amplify little differences in color. In combination with the “Magic detail filter”, you can exegerate the results even further. Also you can use “Boost chromacity” here.
I like “Specific saturation” made by Garagecoder. I still hope he will work on the possibility to seperate this for shadows, midtones and highlights. A bit like Tom Keil’s “Vintage style” filter. Then this will be one of the best color correction tools there is.
“Color grading” by John Lakkas is still a favourite.
Iains “Pyramid processing” is nice. Maybe it is possible to make this filter with seperate sliders for the different scales? So it becomes multi-scale?
I like all details filters. Most favourite are: “Local variance normalization” , “DCP dehaze.” and “Details equalizer”
“Local processing” is nice but sometimes has border- artifacts. Question: “Maybe with some border-expanding or other treatment this artifacts can be less?”
“Retinex” is good, but I prefer Garagecoders “Normalize brightness”. His “Auto balance” and “Temperature balance” filters give good results.
Of course “Samj’s corline b” is nice also.
So thank you very much, for all this awesome work.
(I forgot so much: everything with 3d-luts, curves…)
