Wink Tap the potential?
Imagine the same sensor with Nokia algorithms!!
Wouldn't it be stunning
I have a doubt, If anyone saw OnePlus One phone's camera capabilities, especially color reproduction and its HDR vs Z1.....
Can the software in it be ported to CM11 as Oneplus runs CM11!!

I tried this for myself now since I had a hard time understanding what the difference is.

Anyways, I shot similar photos like you did, quite alot of black things in the photo. And my ones look just like your locked bootloader ones.

My phone has been unlocked once but is now relocked with flashtool. Meaning I don't have the DRM keys present.

Stock firmware,.757 and not rooted.

I haven't tried this with UB though.

I insist there's a difference in picture quality. To prove it, I took a total of 12 shots. 6 shots of the same subject in a row in 15mp manual mode with 400ISO in UBL, and then I relocked my BL, restored my TA and took the same 6 shots again in the same conditions merely 10 minutes later.

I took 6 shots so that the 'random picture quality difference' is negated.

Here are the pictures. I can provide originals as well if people wish. I uploaded to imgur because it's easier for me.

At first glance, they look similar. HOWEVER, if you look into the dark part of the images, you will notice something different in UBL compared to LB. There is a lot more 'digital noise' present in ULB pictures. What I'm talking about is random green/red pixels in the dark area that the BIONZ processor (or whatever else) removes in locked bootloader state.

EXAMPLE 1




Left is LB, right is UBL. You can notice the difference immediately in the blacks of my PS3. There is noise present in the UBL part that is NOT present in the LB part. Picture quality is NOT compromised, both are about equal sharpness, however LB looks considerably better because of the lack of 'digital noise'.

Example 2



Again you can see a greenish hue on my heater with some of that noise that is not present on the left LB picture.

Example 3



Look at the blacks of my HP box. Again there is that random green/red noise on the UBL pictures that isn't present in the LB picture. LB picture is also slightly sharper but that could be a coincidence.

This isn't a one time occurrence.. This 'digital noise' exists in ALL of the 6 UBL shots I took, and it is NOT present in my LB shots. In daylight the difference is negligible, but in low light the difference is evident. That noise reduction that occurs, whether it be through BIONZ or whatever else, is not present in UBL shots. This results in lower picture quality especially in low light. I don't know what is removed, but there is a definite difference between the two.

Look at the colors on example 1 and 2
In UBL is better

Color balance is random. It's sometimes better on LB, sometimes on UBL. LB is better in lower light areas where UBL camera does not apply noise reduction resulting in the 'digital noise' in my pictures.

There is no much change in back camera.
But, front camera gets really worse. It gets noisy so much.
