Re: Can one achieve HDR from one image?

Thank you Palms and thank you Janet.

I was a little surprised myself at the images that could be produced from a single RAW file processed as an HDR.

Re: Can one achieve HDR from one image?

I've tried to do HDR with a single image and have not had good results. According to the books I've read it doesn't really work with one image. you can however tone map a single image and get a decent HDR look to it. I've had decent results using Photomatix and a 16bit TIFF.

I've played with the Photomatix Photoshop free download and, for the most part, it does a very nice job.

However, I find sometimes the noise created to be unacceptable.

What have your experiences been with the product?

I wouldn't be surprised if it was me...

Re: Can one achieve HDR from one image?

Yes you can, but there are some tricks. First off, using Photomatix's ability to convert a raw image into a pseudo-32-bit image has limited potential. What I've found to work much better is to take an image and open that image in Adobe Camera Raw, save that image as a tif, then while still in ACR, drop the exposure value 2 stops and save it, then push the exposure value 2 stops and save it. Then process those saved images as if you had taken those images with three exposures in your camera in Photomatix.

If you like to really really push the shadow region in images to achieve the fairyland look, you probably will be dissapointed. If you like creating realistic images, you will be generally satisfied. You will NOT get as good results as if you had take the three shots properly.

Below is a link to two different photos, one was taken with my Canon 30D and was a raw original, the other was taken with my Olympus 100RS, a 1.3 Megapixel camera and had a jpeg output. Can you tell which was which?

Photomatix does a good job from one image but you (most of the time) get better results with multiple, AEB, images.
