Op THANK YOU for taking the time to do some experimenting. Surely the 7D2 has taken huge steps in controling the banding issue that has be a thorn in my side and many others.
Ok, that does make sense. I don't have any personal experience with that type of shooting. I find it quite interesting that I have been doing this for about fifty years, and I can still learn a new trick. Thank goodness for the internet and sites like this. Now to figure out how to apply it.
George - Normally when doing landscapes one will expose for highlights first, that way a sky isnt completely blownout to white. If you expose the sky close to correctly (with canon sensors) the shadow area is not recoverable due to the hideous noise contained there in.
Here is a scene that could not be done with a single exposure.
I enjoy being able to see detail in the rocks as well as detail in the sky. There are some who will expose for the sky only and the shadowed area would simply be blackness.
