I should have read reviews

There is no way to really change the f-stop so you get a lot more light in the picture than you think you want. Also very annoying ads for deer Hunter pop up repeatedly. Perhaps a good start on this but they really need to put a lot more control into the app, and de emphasize the advertising.

If you want to make a demo app, why not limit the resolution and stick the banner ad at the bottom of the photo or something, rather than interrupting the user experience trying out the app? The current approach really cheapens the app and shows you that they only care about selling ads, not making a great app. Insanely un- great.
