I have tried several different setting on AEB. Pure question for YOU. What is YOUR opinion of the amount of offset of F stop that seems to work best for YOU? I shoot raw with the REBEL, but when using the XTI I use JPG because of excessive noise with the XTI. So the question then becomes which works best with BOTH modes RAW and JPG? I don't use AEB generally, but when shooting images I may not be able to repeat at least soon, I do use AEB. Give me your best results, maybe different rates for shadows and backlighting etc. Thanks.
