    I would guess this matters a lot on the computer too - what operating system you are using and what photo software you use. Some programs recognize the rotation, and others don't. Though, as I said before, for me it even varies by camera for what is recognized.

    You should distinguish between rotation 90 degrees or any thing other than this. 90 degree rotation is losless in many programs as simple is Xnview, as it is just by Exif data not the picture itself, but the other rotations is every time with loss and also depends on the resampling technic which is applied. In my experience I have found Lanczos the best one, after that bicubic, although a lot of programs do not provide Lanczos, so go with bicubic.

    Hope this helps

    Yes mainly 90 degrees. All I remember on my Kodak camera when I inserted the memory card everything was set

    In Canon it is not.


    I am using XP
