The camera on the iPhone 4S is so good that you will take pride in most of the pictures and videos you’ll snap and record. However, if you own a video-recording capable dSLR or an HD camcorder you probably know that these imaging devices are capable of snapping a picture while recording video.
The default camera application on the iPhone unfortunately does not allow you to do that (take a hint Apple!). However, for $1.99, you can grab an app called QuickPix which will let you do just that! Aside from being advertised as the fastest full resolution bursting app, QuickPix allows you to capture a shot as soon as the camera is launched. And the most interesting feature: “VideoPix technology will let you keep snapping photos” while shooting video. If this is something you’ve always wanted, head over to the source link below.
