the only lighting in these pictures is tank lighting, which happens to be a large array of high output LED's. i could set longer exposure maybe? flash does not work with aquarium photography.
open up the aperture BIG TIME. Take advantage of your fast lens, one great thing about aquarium photography is getting a really small depth of field so that 1) your corals pop out from the background and 2) so you can get truer color of the corals. the images are too dark to be able to enjoy the popping colors of most your corals.
The coral is beautiful but like stated before the pictures are very dark...Maybe try to set up so auxualliry lighting like a lamp or something beside the tank. Just anything to add some more light. Opening your aperature may help to make it pop out as well. Cool clown fish though. I wish I had the money to get a saltwater tank set up..lol
Nice shots but I agree about the darkness. Looks like you have a nice setup there. How about a pic of the whole thing? I'm getting ready to set up my first salt tank, just a little 37g.
here's a shot of the entire setup. its a horrible picture. i had to take at an angle to reduce glare...
i'll take some more photos tomorrow. i'll try to get something brighter. i had just figured out how to use manual functions on the camera the other day. as for the clownfish, i find them interesting as well... (no not the whole finding nemo complex) i have four of them in my tank, and there should be another in in the picture, but it must have been on the other side of the coral.
