Hi Graham,
Thanks for replying. I've just tried setting the backside image to be the same as the front image but it still doesn't work.
Are you sure you are not using CIPageCurlWidthShadowTransition in your project because that works for me without a problem?

I haven't got the source to hand though I can dig it up, but running the app here shows a correct curl effect - BUT the proviso would be that I use the same image for the front and back images, so that the reverse side of the curled page appears as a mirror image to the front side. This is how I think the effect may be expected to normally work - so much so that perhaps it is assumed and if the image is not the same image as the front it won't work?

The problem is that the inputBacksideImage value option for the CIPageCurlTransition filter doesn't appear to work.

I suppose the reason why I am still actually dubious that it is an Apple bug is that there is absolutely no mention of this problem on the interwebs. I'm surprised that I'm first to hit it. The only possibility is that people find it doesn't work and try the CIPageCurlWithShadowTransition filter where assigning the inputBacksideImage does behave as expected and just use that filter.
