[Xperia Z3 General] Arxelance:
Hello Everyone!

I just want to share my thoughts on the issues that are experienced by the users here.

So here's my story, I bought a new Z3 (D6653) and I have tested it for a few days now. I was impressed by its performance and battery life! I already read many articles regarding waterproof, audio, camera, battery. Now let's focus on the camera issue (pink issues) which others reported based on their captured photos.

I made this thread in order for us to answer a mystery that has been long haunting the Z3 users.

================================================

Problem: The photos taken from the camera of Xperia Z3 has pink spots issues. This can be seen even on white surfaces. This can be hardware related issue.

================================================

Initial Theory: Software issue, settings, tweaks can resolve this

Note: The higher the exposure, the brighter the image

Observation Summary

: As seen on the photos captured on the devices, there are difference on the color output depending on the white balance used as well as the exposure value. I haven't tested the ISO settings yet.

================================================

Initial Conclusion

The pink spots that we are seeing are RGB tints that can be caused by the white balance. It is not just only pink, it can be green, or blue which represents RGB. Thus, proper white balance and exposure should be able to lessen the tints or fix the color of the photo. In photography, white balance settings depends on the lighting of the environment which affects the proper color of the photo. White Balance Auto (WBAuto) adapts the lighting of the environment which produces the color based on the pattern of light.

This is a software issue on the white balance settings of the Xperia Z3's camera and a software update could potentially solve the issue. Proper camera settings, especially white balance, is recommended to produce the desired and correct color output.

If you have any thoughts on this topic, let's collaborate in order to partially fix (if not fully) these concerns. Speak your mind, share your knowledge :)

I also want to reach out to any professional photographers out there if they may share some knowledge or some points on these topic. I study basic photography but I'm not Pro enough.
