Tap on the Original which will pull up a save and edit button... tap the edit button and you'll see an adjust page and a fix page... the red eye fix is on the fix page.
I have had instances where red-eye is visible but undetectable by Creative Studio, so it could not be fixed. If there are other apps that can do this well, please list.
Ya happened to me in the photos I tried to fix. I did have another question on photography. I know about smart shoot and its a nice program. My wife took some shots at my boys birthday well needless to say in one he looks awesome and I don't in the other I look good he doesn't is there a way to swap faces for these pics? I know that's the idea for smart shoot but of course she didn't use that taking the photos.
