I'm getting more depth of field around the frog, but my worry will be that any dirt on the glass might start to come into focus, so that's what I'm balancing. I want as much depth of field to carry the frog, but I don't want to be seeing the, the schmutz on the glass in front of me. another thing, if you remember we went to two-hundred-and-fiftieth of a second when we first started shooting the flash pictures, that was to kill the ambient light. So, the ambient exposure, in here, was a 20th of a second at F4, at ISO 800, if I'm remembering correctly now. Right now, we're working at two-hundred-and-fiftieth of a second. Which is adding, okay, let's, let's call it a 30th of a second just for ease, a 60th, 125th, 250th.
