Hey I'm sorry for replying to your post, and all I was trying to point out was that even with the tape in place you will end up still with red eye from time to time. Even in your example images you did not display a before image with red eye, or your "demon eyes". Actually your example only showed a reduction in flash output. You already know that the flash is not as powerful as the xenon flash of the 928, and with the tape in place you are only reducing the output from the flash.
Your original title was how you "improved" the flash, and you mentioned your reason was because of horrible red eye. However your example did not show this "improvement". Your original rant was too about the underpowered flash output of the Icon, but your improvement again does not address this problem, it only exacerbates that problem.
I was only trying to address the issue you brought forth. And I only brought up PhotoShop, and editing images off camera, because just about any on phone program should be more then enough. But if you end up with any image that's too much of a problem going off phone would be what you need.
You want to edit on the go, and just about any on phone editing program should be able to take your under lighted images and be able to brighten them up. Not because of the taped up flash, but addressing the difference of the non Xenon flash. The red eye problems, YOU should be able to fix that problem, seeing you "understand why red eye happens".
Again I'm sorry for replying to your post...
