iBooks Brightness Control
Hi guys, just thought you'd appreciate this bit of info:
Just tried out iBooks for iPhone, it's pretty damn slick, the PDF reader kicks butt.
Anyway, playing around with the brightness I've discovered it actually goes much darker than the iPhone screen normally does. I think this is a really awesome function because it will greatly increase comfortable readability at night time while avoiding eyestrain.
I think the way this is accomplished is that they overlay a black image over the whole app at 50% opacity or something to make everything darker, as you can see that the app-switcher is not anywhere near as dark as the iBooks app in the attached screenshot.
Just thought this was interesting!
