HDR process question

[Alan]

Yes, there are limits, and depending on the distance moved between images, you'll end up with ghosting. It will probably be severe, in this case. Sometimes, you can use just two images to complete the HDR with a moving object, but I doubt you'll get good results with the moving boat. If it were a big boat, moving slowly, your chances of success are much better.

Basically found out how others are doing HDR's of moving subjects. They take one image, tweak copies of it with several different exposures and then blend them.

Some may not consider that a "true" HDR though?[*-)]

There's a post here somewhere (or I think in the news section of The
Digital Picture) on step by step HDR image. One requirement is that you
shoot in RAW, split them up and combine them in Photomatix. You'd be
lucky if your cam can support -3 to +3 EV (I had a 50D, which only has
-2 to +2 EV). For moving subjects, this is the only way to do HDR (as
of now). Ghosting will still be an issue with multiple shots.

Here's a sample taken with my 350D +18-55 kit lens + CIR POL, handheld single image to make this HDR pic.

Here's a sample taken with my 50D + 24-70L, handheld with three shots to make this HDR. Some ghosting were eliminated but some remain.
