John and fellow photogs......
John, we only met once very briefly a couple of DEMA's ago. but I really enjoy your posts as totally unique and promoting more of a thinking on the impact of any image....
I agree the equipment today is so good, that with a modicum of practice people can get spectacularly totally lit tack sharp images. That DO tend to look the same whether macro or wide angle images.
I often preach to travel and Ikelite gear customers the gear allows you to get RAW material, and editing it into the vision you preconceived should be the goal.
I myself am guilty of going underwater and shooting the same old, same old. Because it is hard to go in a "different" direction photographically, as in moody shadows, possibly available light (with or without a Magic Filter), B&W images or whatever.
I often think photographers go through several plateaus of capability. Each one being better technically but the hardest plateau to attain is is to develop ones own "style". Alex Mustard has one, David Doubilet has one, Chris Newbert has it, plus many others.
I continually find myself reviewing my images and immediately writing a NEW index card with ideas to try, both above and below the waves!
Many times my pictures are more journalistic, i.e., trying to tell a story.
One example: I am definitely more an "Into the Blue" type of diver. Constantly trying to minimize my "kit" as I believe it helps my photography. But I have HEAPS of photos of friends using rebreathers or in technical dive gear. These look way cool in photos and the images I try and create attempts to portray the danger and technical required risk and gear of this type of diving. I'm supposed to take photos of 3 friends all training on CCR (closed circuit rebreathers) in a pool this week. And I'll shoot it free diving!
I also think we seek approval from like minded fellow enthusiasts, and go with approval from peers versus pleasing ourselves. This is not uncommon in any artistic endeavor......
Not sure if I covered all I wanted to say, just more ramblings from one still kicking and exploring photographer
