The original question is how much post-processing is too much. Possibly if you post-process to the point that the image is so color-saturated that it's turned black, you might consider that you've done too much. However even that can be argued. So probably the way to know if you've done too much post-processing is if you yourself look at it and say, "Ew." If you look at it and you're happy, then probably you've used just the right amount of post-processing. Because your opinion of your own art is the only one that counts. --Alice
