Here you go Frank, as requested, the original and the processed version for comparison. I like the original as well but some bits like the eye being completely black bothered me a bit. the slightly HDR version adds just enough detail back into the eye for it to not look like a black hole.

OK Martin, I can see your point as it is quite an improvement in the eyes. For some reason I was thinking the feathers were too, well I don't know, fuzzy or something. I can tell now I was mistaken and that is just how the guy looks. It did also bring out the detail in the feathers around the eye. SOOOOO in retrospect, Good job using HDR. PS, if you crop a picture before you use the HDR does it act differently? should it only be used on full scale JPG or RAW files then crop?? Thanks for showing me what you did. Frank

Cropping before/after the HDR can make a difference but in practice it's not worth worrying about. I always crop first, resize to double my final requirements, process then do a final resize and apply a gentle unsharp mask.

The reason I asked is that using your program I have some areas on the rendered picture where there seems like too much hdr is used or something. Blown out spots with high number of areas that look like boxes or something. I have not posted any as they look horrible on my screen after processing, and wondered if it was sometning I was doing by cropping or something. Frank

Square shapes are usually jpeg artefacts - they'll tend to be 8-pixels square. And they do occur more in the blown-out (or close) areas because in the original the eye can't distinguish the very bright and very dark levels as well so the jpeg algorithm compresses them more. When you then process, the artefacts can start to show up.

AutoHDR tries to be a bit more gentle at the extremes but you can still push it too far. Try to use the best quality jpeg or if you have the RAW file and can convert it to an uncompressed 16-bit TIF then you should be able to use that instead with cleaner results.

Hey, Thanks, I will keep trying although I was using a raw file 7megapixels or so I think it could be my monitor??? I will send one to you to show you what I mean if you like and maybe you can set me on the right track..... Thanks again, Frank

Yep. Looks like the jpeg compression was set too high to me due to a bug in an older version which set it to 95% instead of 5%. I've sent back a version with the correct setting which doesn't show any bad artefacts.

Thank you Martin. I appreciate your patients and help with this I will try to use it again on some thing else and see what is what. I do want to use this as I feel it is something that will benifit some of my photos, and it was so nice of you to share it with others.. Frank
