Thanks for the explanation. I see no problem with changing things to get the image to look closer to what it really was when being seen and photographed. Thats called "Getting the most out of an image". I use Photoshop for most slides and images here, and for some video, especially older stuff from vintage film. In one "Color Corrector" program you can adjust brightness, contrast, colors, and saturation. In another you can adjust sharpness, but all these have to be tempered so that things don't look too pixelated or just plain goofy. One description of over-doing stuff is that it looked "Cartoony".
In these shots below of 493 that I took with a crappy Kodak Instamatic back in 1968, I have done a little work in Photoshop, with cropping, color saturation, and exposure and sharpness. The shot of pacing 493 was terribly crooked as we were hanging out the back door of a truck camper shooting those images. So Photoshop was a big help making a presentable image out of something where the original makes the photographer(me) look really bad!!! Here are 3 images I worked on a little.
