How sharp is the camera with that lens on the surface? How long is the shutter open for these blured shots? Have you tried increasing the ISO to have the shutter open for a shorter time to see if this recuces the blur?

Too my eye the shot might benifit from a bit more exposure. The black needs to stay black of course, but if the body of the squid was a little brighter it would be a more dramatic contrast from the black. This might be able to be done in post if you have photoshop and open as a camera raw then paint the squid with a + exposure brush.


In Topic: blurry fish shutter speed advice

That is a very good question. I remember coping with a similar problem with my D-200 setup a few years back. It turned out that for some reason when I shot A priority the shutter was staying open longer than necessary and even though 99% of the light was coming from the substrobe flash (that lasted at most 1/1000 sec) the movement of the fish coming after the flash had enough ambient light to allow the fish to have motion blur.

 

But it sounds like you are already shooting in M mode and that was my solution, so I hope someone can give you a better idea. Have you tried setting the ISO to 200?

Suppose a photographer spots a mimic on a sandy bottom and looking around see the hole that is likely the hidy-hole for the mimic. Would it be ok to block the entrance to the hole to keep the octopuss out for more pictures?


In Topic: My New Book: Underwater Photography Masterclass

I had the book on order from Amazon for about six weeks, but I had to cancel. It does not look they were going to get it to me before I depart on my summer trip and I don't see how having it lay on my door step for eight weeks will improve it.
