Too dark, help please


Hi,
I am trying to take photos of my fish in a brightly lit tank using my fuji s602.
i am using manual settings of iso 1600 and apature 2.8
the problem I am having is at a shutter speed of anything over 1/4 second my camera says its too dark and the images are almost black. but to get decent photos I need a shutter speed faster than 1/200th, preferably 1/400th.
any help or advise appreciated. thanks

  If you use a flash, you may get a glare off the glass. So you'll have to play around with a polarizer.

  hi, using a flash is not an option as it stresses the fish and may cause illness or kill them. to the naked eye the tank is very brightly lit, as in bright sunny day outside. the camera seems to stuggle with any indoor shooting and the autofocus seems to be very tempremental indooors, do you think there could be a problem with the camera?

  so all those documentaries and ocean expoditions are out there killing fish and giving them the flu? I'm not seeing that.
I doubt it's the camera and the tank isn't lit like it's sunny outside. You have to add light, and do it from the top and shoot thru the glass.
Never heard of fish being that wimpy. Unless they're from Canada.

  Good one gregory!

Well have you tried taking the photos with the faster shutter speeds anyway(or at least 1/100 or 1/80)? I know that my camera's meter sometimes says it's too dark, but I take the photo anyway, and it looks just fine(maybe a little underexposed).

  I've read several posts similar to this (not the fish part).

It seems to me that if you are looking for a shutter speed of 1/200 or 1/400, you would use Shutter Priority.. then start with ISO 1600 and work your way down or up. If the camera will not autofocus, then focus manually.

Is my thought process incorrect?

  thanks for the input, im pretty sure its a problem with the camera, in a well lit room it says it says an apature of f2.8 and shutter or 1/4 second is underexposed at iso 1600, I know when I first bought the camera it seemed much more sensative and would work in almost darkness at apature f11.
going into town next week so I will take it with me and get the guy at the shop to have a look at it.

  Almost darkness at f/11?
A well lit room is relative. Need to see what regualr outside pictures look like.

  sorry greagory, I guess almost darkness is a relative thing as well, and I mean within reason of what could be expected.
its a really dull day here at the moment but I can still get 1/400th at f2.8, maybe I am underestimaing the difference in the amount of light normal artificial lighting indoors can produce compared to natural light.
