Cameras don’t see images in the same way as the human eye. Digtal cameras normally process the images they capture to get the best representation of what the camera’s software engineers believe are realistic. So if you take a photo and save it to your camera in jpeg format, you’re getting a good approximation of it, not necessarily a realistic representation.
I save my photos to my camera using RAW format, which means that I capture the data exactly as the camera sees it. I then use photo editing software to create the image exactly as I recall seeing it when I took the photo. Is this ‘photoshopping’? Or is this producing faithful images in the same way that Ansel Adams and Henri Cartier-Bresson did a hundred years ago?
Apart from cropping the images, all I do is set appropriate levels and colour adjustments. I regard that as being acceptable. Other photographers do an awful lot more post-processing but I don’t think the worse of them for doing so.
