I think we need to remember that back before digital...most of us did not do our own developing of film!  We brought it somewhere to get processed... not knowing that there was some kind of postwork or enhancements done on the prints to make them look good. It was all done behind the scene and was pretty much taken for granted.  I think now we all realize the work involved on some pics.   

Out of all the photos you see posted these days...how many you think are straight out of the camera and even then, it depends on the settings one used at the time, not to mention if the camera does it  own thing...  like noise reduction or compression.    All  of these can be considered digital enhancements in one way or another.
