I tried a few times, but got a couple rejected. It seems like a frat to me. I could submit pictures that were better than some photographer's worst, but I'd still get rejected. They said it was quality. I say it was because I wasn't already in the frat. Then again, I'm sure if I was in it, I'd get the same benefit of the doubt, but it's still kinda shady. The nepotism on the site bothers me.I submitted a photo once and it got rejected. It wasn't one of my best, but I figured I'd have better luck with JetPhotos. Airliners also changed their Terms of Use which created a bit of a controversy, so I figured I'd stay away altogether.
I'm guessing by HDR you mean high dynamic range? I'm not quite sure what that is (if it's a photography technique, camera setting, or post processing trick... I think the photo software I use, Ulead PhotoImpact, has something like that). Anyway, all my night shots are just 5-15 second exposures (15 in this case) shot in shutter priority mode, usually at ISO 100. I set up my tripod, take a few test shots, tweak the settings, and hope for the best! I was surprised it came out the way it did, considering I thought the area of the ramp it was parked on is poorly lit.On the C-130 pic, is that HDR?
