5DmkIII Double Exposure mode.

[Kyle Bultman]

Does anyone know if there is a way to do an in camera double exposure with different ISOs? The 5DmkIII limits me to using the same ISO as I did on the base image.
Was this fixed in a firmware update? Also, do you know if it is possible to keep a base image selected and then shoot 10 double exposures each with the same base photo? It really slows me down to try to perfect a double exposure when every time I try one, I have to start over by finding and selecting the base image again.

You can change the ISO at any time, you are not limited the the ISO you uses inside when you go outside.

To do a double exposure on a DSLR you will just take two normal images and them blend them into one on the computer.
