Photo Q&A

1: HDR images

Is it possible to make an HDR (High Dynamic Range) image from one Raw image? Or do you need several images?
- Mike Howe

Yes. Not much difference than the expected way of taking several photos of different exposures. Raw file converters have exposure adjustments. Or you could pull detail out of different areas, which is another way of saying lightening or darkening areas. I'm sure there are several programs out there (tone mapping, etc.) that will do a large part of the work for you. It's just the dynamic range is greater with using several photos.

- Gregory La Grange

Topaz Adjust has a single image HDR preset. You have to play around with it a bit, but it does a fairly good impression of an HDR shot.

- Carolyn Fletcher

Hi Mike - You can quite easily make an HDR image from a single Raw file (and in fact, while the dynamic range may not be as strong as combining different files of varying exposure levels, you have the advantage of not having to worry about aligning the images, motion distortion, etc.)
The trick is to create multiple different files of varying exposure levels from the same source file. When I create an HDR image from a single file, I typically save anywhere from 3-5 TIFF files of the same source image but with varied exposure levels (e.g., -4, -2, 0, +2, +4).
Specifically, I open the source image in Adobe Raw, adjust the exposure level to the desired amount (leaving all the other adjustments levers constant), save the file as a .tif, then repeat the same process until I have 3-5 .tif files all of the same image, but with different exposures.
If you use Photomatix, you simply have to load these exposure-adjusted files and go through the HDR process the same way you would if you had multiple images.
As with all HDR images, once you are done tone mapping in Photomatix, you can reopen in Photoshop and make additional adjustments as desired (e.g., noise reduction, sharpening, curves, etc.)
One disadvantage of the single-file HDR method is that it tends to produce much noiser images in the shadow areas.
Hope that helps!
