Being a diver, they are very cool to spot and observe.
Describe the mono elephant shot if you don't mind.
Agree with fstopprookie. And, IMHO shutter speeds above 1600 will result in static photos. I shot HS soccer and found 500 to be ideal on producing clean images with just enough ball and foot movement to show action.
My choice would be a 5DIII, ikelite housing, 2 ikelite ds161 strobes (warmer 4800k) and arms, lens ports for 100mm macro and 10-17 tokina fisheye, and pelican case. But, that's a lot of equipment to tote on boats and airport carry ons .
Things to consider:
1. Size: UW SLR outfits typically consist of camera, camera housing, wide angle and macro lenses, lens ports and domes, flashes, flash extension arms, and transportation cases. That is large and heavy, but will produce great quality.
2. Price: The above set up will be $2,500 - $10,000.
3. Output: Are you after photos or videos? I prefer photos, but most non-divers appreciate videos.
4. Format: just like land, cropped can't be enlarged as well as FF. And, you don't typically capture anything beyond 10' away.
5. Depth: some non-SLR housings only go to 60'.
Many other considerations. But, you really need to ask yourself these questions. Then, find the set up that meets your goal.
Did you sit and breathe in #3 before shooting? Just seems appropriate.
I love the pop up flash and use it all the time - as a trigger to my remote flash.
That is impressive. Share details if you don't mind.
Something to consider -
It's been a few years, but I had a basement darkroom with Beseler 23C, condenser and diffuser heads, color analyzer, the works. I can go overboard sometimes getting technical. I bought and developed bulk film (tri-x was favorite), and did B&W and color from slides (I think it was Cibachromes) prints up to 11x14. Everything worked great and I spent a bunch of time enjoying - even won some local contests.
The one thing I remember that was difficult to control was water temperature - especially during warm seasons. Winters were fine. Summers were a challenge with tap water being too warm. Check the chemicals you plan to use regarding suggested temps.
Visited the Czech and Prague as part of an international MBA course. Professor arranged guided tour. The guide said to me before we departing that tourism will be the death of Prague. I did not understand, until after the tour started.
My bad, lock 17, not 17 years ago.
Great shots. I believe I visited 17 years ago. Two things I recall: 1. Whatever lens you brought, you needed more lens; & 2. It was bone chilling cold when the eagles concentrated below the locks/dams.
Agree with others regarding over PP. The one thing I would suggest in PP is blurring distracting background (white spots over players shoulder and gentlemen in upper left. Additionally, I'm a big fan of sports movement. With soccer, 1/500 SS allows for foot/ball movement, but can still freeze remainder of players.
