iPhone Photoscreening |

Home |
The iPhone 4 (and iPod touch) has a small flash very close to the small 5-8 megapixel camera. From a distance of 3-5 feet, it is capable to generating a good photoscreen. Unfortunately, the default fuction is always to have red-eye reduction pre-Flash that constricts the pupils moments before the image is taken. (GoCheckKids- An APP that over-rides the pre-Flash, could also find and interpret photoscreen crescents) | |||||
