I’m not at my computer now, but if you load the image using the thumbnail option it will give you a properly oriented image. I’ll check the specific options when I get home and can look at the code. If you’re using CIImage anyway, you can render it back to a CGImageRef with a bitmap context, and that can be done in a separate thread as well. Then you have a rendered bitmap ready to assign to your CALayer contents property.
