Keri in KS asked:
I shoot 3 brackets with a Canon 5DMkIII and process them with LR/Enfuse but when I shoot towards bright windows the windows turn out too bright even though I expose for the darks inside the windows. I also get some color casts. What can I do to fix these problems?
The problem causing the windows to be too bright is that when you shoot brackets your brackets are not capturing the whole brightness range of the room. This post describes a way to make sure you are capturing the whole brightness range of a room. With this technique, you use the histogram in LiveView to let you see the exact brightness range of the room. You move the histogram all the way to the left where it starts to crawl up and touch the top and then shoot brackets every stop as you use the shutter speed to move the histogram towards the right. Stop shooting brackets when the histogram crawls up the right side and starts to touch the top.
For your color cast problem, if you use a single manual flash bounced off the ceiling or wall for some or all brackets it will make all the colors more accurate and the whites whiter. Experiment a little to see what the best power setting is for each room. You don’t need a lot of flash power to fix color casts.
