imo if your using photoshop to fool others i dont like that, for example, if you did a correction and still left buffer swirls then edit picture to not show those well thats a problem, however if your just trying to enhance the photo into what your eye see's then its fine to use. sometimes you need to edit pictures but most do that to bring out true color, or true condition of the picture. that is fine as that highlights defects ect. but if your trying to hide something well thats just lying. in all honesty photoshop does not bother me if your using it to enhance the picture to the true naked eye image. but if your say adding some wheels/body kit to a car and passing it off as your own thats when it should not be used unless your stating its what you want your car to look like ect ect....however if you take good pictures then you shouldn't have to use photoshop besides converting,resizing,watermarking,and light color enhancement..unless of course your vision is doing an artistic shot...
p.s most dont know that the top point and shoots(ones that look like a d-slr) you can get some lenses and filters for your camera which will help your photos under certain conditions. worth a shot to get some like say you want better macro images get some macro lense filters if your in the bright sun and your white looks yellow get a blue tinted filter for it to bring out the color, then you wont need to do much editing. i have seen some crazy pictures where it looked photoshop but it was the raw unenhanced image....now thats a true photographer!.
