Soo recently asked:
I am a real estate agent and photographer. I like to do my own photos and I have a Nikon D750 with a 16-35mm lens. I use Photomatix for HDR for the convenience and Photoshop to edit. However, I have never learned how to get rid of the yellow color cast nicely in my photos. I tweak around and still can’t seem to get it right. I either remove too much yellow or not enough. I like the photos that have more grays and whites where as mine tend to have more yellows. Help!
Yes, color problems are a classic issue with HDR. Depending on the ambient light in the particular room, HDR frequently produces strange color artifacts that are difficult to remove in post-processing. The yellowish cast usually comes from the incandescent lights, but also the whites are not a crisp white and there can be other color problems that are hard to control.
Here are a couple of ways to get control of your color problems:
- Use a flash when shooting your brackets. You can use a on-camera manual flash like the YN-560-III or an automatic flash like the SB-910 or SB-800. Add flash to one or more of your brackets with the flash bouncing off the ceiling or against a wall-ceiling joint. Then process the brackets as you normally do and the colors will all be more accurate. If you use manual flash, experiment to find what the power setting works best. Half power is a good place to start.
- Another refinement to your workflow would be to use Enfuse processing (Photomatix has it build in) rather than HDR since Enfuse processing results in a more neutral results with fewer color artifacts. You can always adjust saturation and clarity in final post-processing to give a more HDR look if you like that look.
Anyone have any other suggestions for Soo?
