hdr aura

May 18th, 2011
I've always loved hdr and Sparkle really encouraged me to try it more often - her hdr shots are amazing. I'm tone mapping a picture and it has that halo around it no matter what I do. I'm loving the picture but not the halo. Other than spending the next month carefully getting rid of it is there a trick to it? I use elements 7. Thank you :-)

I don't know of a trick. Sometimes, it just happens. That's HDR. It is a balance of luminiocity, and sharpness. Not easy.

Just too much processing. Reducing the strength and luminosity, and/or increasing smoothing will help reduce it. Some shots just don't lend themselves as well to high HDR processing due to the strong contrast between a light and dark subject.

I find that the more I saturate, especially when I'm saturating the sky - bam! Halo city.

The only trick is masking it out w/ the original in Photoshop or a similar editor that allows masking on different layers. Theres a tutorial for it on Trey Ratcliff's site i think

@moncooga @marubozo @pwallis @3nder Thank you so much. I think the masking is what I need. It was happening on one or two shots and the rest were great. No matter what I did I got the halo. I'll look at Trey's site again plus the books I picked up on hdr. Love it for some shots. Again, thank you.

I often get the halo Sue - it is most prevalent on shots taken a low sun or when it is particularly bright but grey outside (ie all the time at the moment!! LOL) I don't pre or post process when I do HDR - just complete all the processing within the HDR package. I tend to find if you drop the strength and the monocontrast and boost saturation this helps. It also depends on how many frames you are using...sometimes if I am using 5 frames i will drop the higher contrast frames to remove the highest of highlights - for a really bad halo sometimes i will jsut tone map using one image. I'm finding i can spot a scene that will give problems and make sure when i focus I bring the foreground contrast more into focus than the bright background - this knocks out the differences in the sky when processing - it may also mean it's not so dramatic - but I guess those are the choices you take! Glad you're enjoying experimenting!

Thanks Juliette. It's an eagle shot that's being difficult - so just one shot. I've done a few others and they're fine. Now that I've read your reply I think it was the angle of the sun at that time. I just liked how the hdr brought out more detail in the feathers but not the halo around him. The masking is helping tho - when I have time to finish it :-)
