  1. In Adobe Photoshop I can do Auto-Tone and it improves the picture quality. Is there a way to do this in FFMPEG? I'm using a color curves .acv file to remove fog/haze, could the .acv also be designed to correct the color tone? Or is there another way using FFMPEG?

    Here is a before and after using the Auto-Tone

  5. Ok I think I figured it out. When I created the curves file in Photoshop I was using the RGB slider. If I use the pull down and adjust the blue, I can get it to look like the Auto-Tune function.

  7. I tried using the RGB blue slider and found it inconvenient. Lots of futzing around. I found that the presets did a better job anyway and gave a simple one step result, like Auto Tone. I liked the results from the Strong Contrast preset best but Increase Contrast was also good. ffmpeg result is identical to Photoshop:

    Strong Contrast preset
