[Suggestion] Capture Image Filters

[MagicBOTAlex]

I forgot where I saw this, but there was another overlay application that claimed to have a filter that would make text easier to read. So I thought that it would be awesome if something simillar is supported in this open-source project.

So here is my suggestion: Multiple sliders to adjust Fx. Sharpness, saturation, Contrast, Warmness? I think you understand. If possible, then having presets for these settings would also be awesome, like: Text reabability, Cinematic, and so on.

Again, I will probably give this a shot. But can't promise it.
