The camera brightness and exposure compared to the iPhone standard camera is literally night and day.
Below I've attached two screenshots of an iPhone 5s, one taken with the default camera, the other through Vuforia's video feed. I've even turned on auto-exposure (*not* through Vuforia) but the images are still extremely dim, making cloud recognition extremely difficult.
Is there anything that I can do through your API that would increase the brightness and exposure of the Vuforia video feed?
I've tested this with an iPhone 5, 5s, iPad 3 and iPad 4, with the same result.
Thanks for reading.
