Taking pictures in low light can be very tricky. Shut all the lights off in the room, you will have to use a tripod and you definitely dont want to use the flash. To take night shots you need to use large aperture settings and long exposure times. The 2800z's longest exposer is only 1/2 second, I dont think thats long enough to get a descent "night" picture tho.
I believe that model does have manual mode...
I would set the camera up on a tripod and use the longest exposure and largest aperture opening (F2.8-F3.0) to see what happens. Using the timer will minimize camera shake also.
Here is a pic I took of my tank lit by LED's. The exposure time was
4 seconds. If you look at the dim greenish blob to the far right of the picture, that fussy blob is a
green bubble coral waving in the current.
Sorry it took so long to reply, I have been very busy lately...
