I recently bought an iSkin aura, posted a review, then received requests for comparisons on how well the iPhone 4S flash works with the cover on. I thought that there would be no difference since the cutout on the iSkin aura appears to be large enough so as not to affect the flash performance. I even mentioned that in my review. It wasnt until I did actual side-by-side comparison shots that I realized how the cover affected the flash, which got me to thinking. How many other cases/back plates that cover the back of the iPhone 4S with a cutout around the camera lens/flash actually affect the performance of the camera flash, but we didnt realize it. Post your side-by-side flash tests of your phone with and without the case on so we can actually see if the case is affecting the performance of the flash. Im thinking that there are probably more cases/back plates out there than we realize.
