When I shoot a photo and load it into my image editing software and start playing with curves and sliders, sometimes I go so far. For example I increase the saturation and I keep increasing it till it doesn't look so good cause the photo becomes very saturated and unnatural, but I don't feel that till someone take a look and says that colors are too strong or I go away for sometime and come back to look at the photo and I say to myself what I was doing! It's too way saturated. Same goes with exposure, clarity, sharpness, ....
So when should I stop myself and say that's enough? Should I always review my photos after editing them by a day or two? Sometimes I can do that but sometimes I have to print the photos and I need to get them done. Any techniques that can help in this situation?
