Lord help me..... was gonna' stay outta this one. Pick your battles and all that....
My wife has been a photographer all her life. Trained as a photojournalist in the Air Force, won lots of awards... She knows her stuff. When she looked at the calendar, her critique resembled your sons to a tee Fred. She said exactly the same. But then she added that...
"for a bunch of amateur knuckle draggers that just love buildin' bikes, it's pretty damn good photography." She gets it.
If you want your Mustang to look like a Ferrari, hire a professional. If you just want your Mustang to look like a Mustang to other Mustang owners, take a shot of it and put it out there, they'll appreciate it for what it is.
Pick your battles Fred. In my opinion, you should have just let this one be.... An opinion I probably should have kept to myself, but there it is. Guess I ain't no better at picking my battles after all.
