As a golf course photographer not mentioned by Alex Miller, I cannot speak to what my impact has on costs in the golf industry.
There was a time when LCL was the go-to photographer in the western hemisphere. Jon Cavalier got his start here, then branched out to LinksGems on Instagram. His work was then gobbled up by print magazines. Jon's early work was enhanced tremendously, and I recall the author of this thread calling him out for it. Jon, like all of us, improved.
Joe Bausch has done great work for years, and has resisted the siren cry of enhancement. A young, landscape photographer would do well to study his work.
I have been hired by a few clubs and courses over the years, and I have my own method for thorough shooting of a course. I don't drone, so all my work is land-based.
I do my best to not botox a golf hole, unless I am doing it for art's sake (and I state explicitly that I have Warholed it.) If a photo is awesome, but the coloring is improperly poor (the vagaries of lens/body interaction) I will gently massage it.
I am open to any critiques of my work on the @buffalogolfer instagram feed. As photographers, we are grateful for any insight. We certainly don't wish to contribute to the obliteration of golf.
