Thanks. Wow...I was wrong about that one. I did not know that with a camera alone you could create whatever image you want from almost nothing. While accurate in theory I still believe the picture to be make believe in reality.
I think that "make sure the photo depicts reality" is probably the photography equivalent to golf's "play it as it lies." Yes, there are exceptions to both, and when most golf photos are used for marketing, minor enhancements are probably acceptable, but like other products, the advertiser shouldn't be allowed to outright lie (i.e., Lose 50 lbs. in just one week!). Many enhancement issues are in gray areas, subject to opinion. Some would call women wearing makeup as false advertising, for instance.
I was once at Giant's Ridge with a noted photographer. While most I knew shot only in the early morning or late night, he just shot photos all day, and changed the lighting to look like early morning with Photoshop. He even added snow to a few photos, so they could send those out as Xmas cards. For a short while, that ability had to be a competitive advantage for him. Basically, most golf photographers had to set aside three days to make sure they weren't delayed by rain, etc. He still probably had to set aside two days, but usually got done in one day, with his nights spent touching up the photos.
