Swimmin' with the fishies.
Great shots! I laughed when I read 'old generation' GH2. That would be the GH2 from 2010? Did they have flash powder then, and those new-fangled wet plates? (my G1 is two years older than that, and still working well) Ah, sometimes I miss the film days when one camera would last a lifetime.
Those blues are intense. They would be difficult to print - 'out of gamut', I think. The ink and paper can only deliver so much. Beautiful to look at on screen, though.
I read somewhere that underwater, lenses have a sort of magnifying effect, so that a normal lens acts like a telephoto. The old Nikonos cameras used 35mm lenses which gave a field of view comparable to a 50mm. Is that how it works?
How do you like the 25mm Panasonic lens?
