I have been lurking for a long time, and finally decided to say hello, and even post. I've been learning a lot, but still don't have a good read on local culture. Still, I will plunge ahead. Please pardon any faux pas on my part.
I try to do both underwater (I am ceedave on the excellent wetpixel site, also) and landscape/nature photography. Mainly because of great DX optics (the 10.5 fisheye), I shoot Nikon. WA is very important in underwater, where camera/subject distance has to be minimized due to the murkiness and/or light-adsorption of the water.
Topside, we have great winter birds around some urban lakes here in Baton Rouge, and I have been working on images. They (the most interesting birds, like ibises) don't come in until the light is low. So it is tough. I am shooting with a fast lens from a tripod, but the birds, they do move. Also, working with a camera (D70) that ain't the best in high iso performance. So I get images like
D70 with 17-55 at 24mm, f2.8 and ISO400 for 4s, with DNR; Gitzo w/Markins ballhead. Additional lighting from streetlight. Aren't urban parks great?
I'd love to hear how others balance ISO, shutterspeed, etc., for this type of shot. I love the mood, hate the blurred beaks.
All the best from a rank beginner,
