This is not really related to aviation, but related to photography.
I have a Nikon D80. I was in a moderately well lit ball room, and i was trying to get shots roughly 40-50ft away with my 18-55mm lens (F3.5-5.6). But even with a flash, a shutter speed of 60, and full aperture, the shots came out dark. Then I tried moving up closer, and the shots still came out much darker than expected.
However, it wasn't due to the conditions. I saw many other people (with much bigger and expensive lenses) taking pictures with DSLRs and they seemed to be doing fine. They didn't even need a flash.
So, what could I be doing wrong?
My lens perhaps? Which one is good for indoor conditions?
Thanks a lot.
