I am shooting some interior photography with a Canon T2i. I am using bracketing. The T2i will auto bracket only 3 photos. So I am starting at a base time set manually, bracket 3, then change the base by 2 stops and bracket another 3.
The end result is to be processed to HDR images, and then stitched with PTGui into 360 panos.
The problem I am having is when I do the straight up shot of the ceiling, 3 will be in portrait, and 3 will be in landscape. The raw photos require extra processing of course to change to portrait.
Anyone have any suggestions as to why, and if there is anything I can do to prevent the landscape orientation of the ceiling photos?
