Well, I used Photomatrix for the process of the HDR, Then I used CS2 to crop and resize pic. I figured I'd Post here because this is where I got all the info needed to creat it. Using the Search Feature Really helps!!!:lol:

As to your post, the image is nice. Good depth of field control. The greens seem a tad oversaturated, and the reds a bit more so.

I'm tending to think HDR is a tool poised to become a monster growing out of control. HDR was originally developed as a solution to problems in digital videography and still photography where the dynamic range of light was beyond the physical capabilities of sensors to process. But now it seems the process is being used just for its own sake.

I would tend to think this subject/scene would have been achievable and within the range of a single frame without additional (dynamic) processing. /Dan

Nice job! Go Photomatix, art for the rest of us! :) I love HDR like this, keep up the great work.

I'm confused. How is this HDR? The red and green channels are blown in the light blur in the background and the rest of the image has a very narrow dynamic range. HDR is about detailed highlights and open shadows.

The Full rez pic looks 1000x's better. This was my Very 1st HDR shot. I took the pics the other day and renderd them tonight. Still playing with the SW to get the best look.. Will practice more when it is not Freezing outside.. 20* is cold.

HDR is useful for few situations. IMHO this wasn't one of them. Basically you want to use HDR when you have a scene with dark shadows *and* bright highlights. HDR will allow you to exhibit both shadow details *and* highlight details on a single image composed from many exposures at different EV. It's one of those situations where a single shot cannot yield a histogram well within the camera's range because you will either lose shadow detail or lose highlight details.

In your case, the blurred background is inconsequential for HDR. The bottle itself could have been exposed quite easily with a single RAW image.

Use HDR when you don't want to sacrifice shadow detail *nor* highlight detail.

I have to agree with ebann on this as other than seeing how the outcome would _ the process did nothing here that one properly exposed image could have accomplished.

HDR is for High Dynamic Range lighting that your cameras sensor can't process in one capture.

Not to diminish your efforts, but if you had played with the shadows and highlights of one shot in photoshop you'd have gotten the same results..

HDR for HDR's sake is pretty pointless.. Here's a good example of a use of HDR..

I must agree on all the comments. The pic I posted really was not that great. I PP'd it while I was at work on a Crappy monitor, When I got home and Looked at it on my LCD I was like, "Dam what the hell is that" Thanks for all the CC's

Don't be too hard on yourself. Even Neo couldn't do it on his first try. Check this link for sample of different exposures and it's histogram and comments regarding what makes it work or not.
