I am not sure you are doing the HDR the correct way......what program are you using and how many different exposures over what range. I think the specks come from you pushing the exposure or saturation too far......

You should have at least 3 exposures one exposed for the shadows , one for the highlites and perhaps one or two somewhere in the middle.

I have never had good luck trying to do it from one exposure even if its a RAW file.

Are you saying you took one photo and then changed the exposure with software....if so,I do not believe that works very well. If the sensor has a dynamic range of say 5 stops you can not increase that with software.

I know nothing of that program......but my guess it is just a case of getting familiar with how it works........I still feel the the specks are from over pushing the exposure orSaturation......I have seen this even in photoshop.

while I can see the HDR effect in the first photo....I am not sure I see it with the gull, I know theshadow part got lighter but so did the highlites.

genece is right, using one shot to create HDR does not work very well.
You should shoot three pictures to obtain a good result.
HDR pictures obtained from one single frame are usually prone to distortions like the one you can see in the sky in the first example you posted.

I like that result.....I am not sure something like the S&H tool and then a high pass filter in PS could not give a similar result.......but perhaps not.

It's hard to judge, being the pictures so small.
But they don't look true HDRs to me. Consider the fact that the "goal" behind HDRs is to be able to "enhance" the highlights AND the shadows, in order to have them both in the same visible range. I'm not sure I was clear but what I actually mean is that in a "real" HDR one would be able to see the foliage even in that dark spot in the center left of the picture, while in your picture one can't.
Your 'HDR' just looks as a normal picture with boosted highlights and more saturation.

Try using Photomatix: I suspect the software you are using is not that good.

Since I read this post I downloaded Photomatix and gave it a try. What do you think?
