Finally, a reason to upgrade to iOS 8.

This is very cool. I haven't tested it yet in the airplane, but hopefully it means the end of the stupid prop artifacts without having to use a light-reducing filter to trick the sensor into using a slower shutter speed.

Check out Camera+, I think I like their user interface better. It also allows manual controls when you update to ios8.

The problem is that you can't adjust the f-stop, it stays at 2.4. And because you can only get the ISO down to 50, the shutter speeds that will blur the prop (somewhere below 1/60th depending on number of blades and rpm) will over expose the image in daylight conditions without using some sort of neutral density filter to darken the exposure. Here is an example from today around 7pm:

Normal auto exposure with the prop artifacts:


Exposure set to blur the prop out (50 ISO, 1/60th shutter speed):


I guess you can't see the prop though...

Still pretty cool that you have some control over the camera though. Very useful in backlight situations, and the manual focus is good for scenes with varying depth.
