Everybody would need to take auto photo shoots for special reasons, and they would not like to miss any actions for a short period.

Also, You could print Date & Time and/or Title and/or Location's Latitude & Longitude ( 4 Different Colours ) while shooting photos.

You can take photo shoots between 1-15 with one button.

You will never miss any actions. You could shoot 15 photos in less than 3 seconds with one button.(iPhone 4,4s,5)

You could connect two iPhone/iPod/iPad thru bluetooth and you could take photo shoot remotely from other device. Also, you will see what have you shoot from other device after shooting each photo.

They are good ideas aren't they ?

For example, Your child has birthday party. You will be with him/her and you should have self timer and auto photos application with your iPhone. What if that application has audio warning(which is recorded by you) while count down for the self timer.

You can set timer between 0-15 seconds.

You can activate/deactivate flash if device have flash.

Also, You could have 5 quick shoots just touching one button. (Quick shoots have not got captions.)
