View Full Version : Anti-ghosting? Wind-blown grass/objects? How to combat this?

I know that Photomatix does an anti-ghosting type thing. Is this meant to remove any problems that would occur with blowing stalks of tall wheat/grass?

I never knew quite how to combat this problem. Even when using a tripod the grass is still never going to be completely still. The same with trees. Even if there is the slightest, tiniest bit of wind.

I like using Photoshop CS4 for my HDR work due to the fact that I can work directly on the 32-bit image and do the tone mapping manually with masking and the exposure tool (this is what the exposure adjustment was designed for actually, was working on 32-bit images). So my real question is:

Does CS4 automatically remove ghosting/haloing/artifacts from HDR?

I don't recall seing an option to do it before it merges.

That stuff only works so well. Your best bet is to take the original photo (whichever one has the best exposed grass, trees, or whatever) and layer it beneath the HDR shot. Adjust the contrast and color to match the HDR shot. Then mask out everything but the ghosted objects. Make sense?

Yeah it does make sense for sure. :) Thanks for the advice. :)
