Interpersed, too.

No problem getting right up to the glass. The nice thing is that the way it is lit is more like a backlight coming out of the tank shining through the jellies.

It really depends on which jelly you are shooting. Some are pretty mobile and some sort of slowly float. >> This is where digital would do way better than >> film.

My experience with color film is that at 800 and beyond, it is starting to looking pretty mediocre. Digital is looking much better at 800. >> This is a case, where there is no substitute for speed.

The shots at 1/10 were not good, but some of it could have been me not holding still enough. At 1/45 there was no motion blur, so you might get down to 1/30 on the slow end. Some of the other tanks are quite dim. My shooting speed was dictated by the light in the tanks as all shots were wide open on that lens at f4. So the general numbers to figure from are: bright tanks: ISO 1600, 1/60, f4 dim tanks: ISO 1600, 1/10, f4 Hopefully that will give you some starting points. >> Most tanks >> are not as well lit as the big one and most of the jellies look more >> white/translucent so you are getting just a white on blue look to >> them.
