Is GDR1 or Black better?
As you can notice in the picture below, the GDR1 in some moments captured less grainy photos due to the lower ISO, but ended up making the image darker:
Photos taken with flash, following the above order
Photos without flash
Frontal camera
In the comparisons, we note that the GDR1 captured photos with more vibrant colors and more contrast. While Black lost in the category contrast (which caused the famous effect "photos washed"), and constantly offered yellow photos, which affect mostly in flash photos. A major problem was the GDR1 with vibrant colors like red, where the camera was a little lost and ended granulating the entire photo is losing between colors. Besides the focus is much more slow and inaccurate. But we note an exception in the photo the Brazil coat of arms, where GDR1 without flash captured a very strange colors and washed. The Cyan update with Windows Phone 8.1 is expected to be released later this month, following the common sequence, tops appliances first and low-ends in order.
All tests were done with a Lumia 720 and the native photo application
Applications like Nokia Camera no influence on the quality being in automatic mode, which is how the test was done

In my opinion, the photos captured with GDR1 were much better.
The photos had less noise, and everything just right. The problem was sometimes the focus and saturated colors.
