Hell, even when I am with a group of people at the bridge... I am still considered a solo diver. It usually takes one-two photo subjects before I find myself diving solo, but it always happens.
There are some of us who will spend 45 minutes attempting to get "the" shot we want, which really bores the heck out of the group.
My average photo count at the bridge per dive is 180...
Editing depends on the number of subjects... If I found 4 subjects to shoot, my edit time might be an hour choosing the image I want... If everything was on the move that day, it might take 8-10 hours to choose those subjects I feel represent my dive.
On top of all that, if I see a minute movement that appears suspect, I will shoot 20 or so images in an attempt to get one that shows what caught my eye... That's how I spotted and identified the "Caribbean Sea Spider" found in our local dive area... and now we have more than 30 sightings of different colors as well (There haven't been enough subjects sighted in any area, in enough abundance to justify capture of the subject to determine any real information... only short sightings of the subject... and enough to know there are several varieties...) NOW, IF THAT AINT A GOVERNMENT PARENTHESIS, I don't know what is... lol
