Hmm... Not sure if this will share right...Flicker-set
Here's a couple of pictures taken with and without flash of a rack of servers and of a bookshelf. The shots include those taken with the ZL, a S2, and a S3...
I would say the ZL does ok... though I like the manual pictures better than the Superior Auto. Alot of noise gets introduced when it tries to adjust the ISO settings to something way past the optics of the phone.
I haven't really looked at the camera on anything pre 2.67...)
Note - the S2 is running T989UVMC6 (4.1.2), the S3 is an I747 running 4.1.1 JR003L.I747UCDLK3.
Both phones are rooted, but are running stock TW roms.
