Nice job from +PhoneArena on this large camera comparison

That's a lot of work!

Note: I only look at the pics and skip all the text as I'm experienced enough to analyze on my own. I don't know if I agree with their writing or ratings.

I find interesting to see that color rendering deviates a lot less from one smartphone camera to another than displays colors do.

If today's mobile display color accuracy is in pretty bad shape, and not making any progress, at least the cameras are pretty consistent and perform impressively in average all things considered!

Thanks +PhoneArena for all this useful data ๐Ÿ™‚

Camera comparison: iPhone 6 and iPhone 6 Plus vs iPhone 5s, Galaxy S5, LG G3, Lumia 1520, Xperia Z2, HTC One (M8)
Apple has been treating its iPhone to camera upgrades with each consecutive generation. However, the company has never been into the megapixel race – as the iPhone 5s and the iPhone 5 before them, the iPhone 6 and iPhone 6 Plus sport 8-megapixel main cameras. Will this be enough for the new iPhones to beat or match the performance of other flagship phones? Well, we’re about to answer this question in our latest camera comparison…

Every white balance algorithm has its strengths and weaknesses

No automatic metering nor white balance is gonna provide perfect result in every situation.

I don't think +Tom's Guide calling this "a big problem" is particularly fair in this article.

Their video demonstration of white balance shifting when the scene changes (hand introduced and removed from the scene) is at best inconclusive, that's pretty much the expected behavior.
If you want to know the reason why fixed or manual white balance is sometimes required, well that's it ๐Ÿ™‚
Maybe the white balance adjustment could be slower, which would make it less apparent, but that would reduce its efficiency in other scenes with mixed lighting conditions.

Also, this sentence shows the author doesn't get how automatic white balance works, by stating the exact opposite of the reality:
In reviewing some of our test photos, Apple representatives said that the colors may have shifted as the result of changing content in different photos. But that's not how white balance works. It takes account of the color of light falling on the subjects, not on the assortment of subjects in a photo

Everything an AWB algorithm has to work with is the raw pixels values from the sensor, and some knowledge of what was going on before.
It doesn't know anything about light sources, weather conditions, light reflections.

Lastly, I don't understand why they qualify this other example as a problem while the iPhone 6 has onece again the expected behavior: exposing for the faces first when there's people, and preserving highlight to avoid blowing out the scene otherwise:

which brings much better results than their reference on metering, a Galaxy S5: http://media.bestofmicro.com/H/R/455535/original/sean-mike_gs5.png
However I agree that the S5 auto white balance gets better results but keeping in mind both get a result that's far too blue overall when exposing for the faces.

I'm all for reporting image quality issues, but it works better with reasonable expectations and proper understanding on how things work, especially when trying to explain that to readers.

As a writer of display and camera calibration software, I have to applaud +Curtis Judd who made this video 2 days ago on the topic of monitor calibration with video editing in mind

I noticed no error or misconception; this is rare enough to be congratulated for ๐Ÿ™‚
You'll see he makes a series of good points on introduction-level questions and explains them in ways that are easy to understand.

Excellent job +Curtis Judd!
All my encouragements and support if you'd like to do talk more about calibration in more videos.

So now, having manually selectable screen rendering presets is considered as color management

You'll find also the usual:
– 2.35 gamma instead of 2.2 but "very good accuracy"
– only 21 color measured at only 100% and 50% saturation to be sure not showing too much of the color deviations

I couldn't read the whole thing, my BS detector was tripped up to angry levels this time.. color management! oh come on. I have no words.

This whole series of "shoot-out" is either result of manifest incompetence or purposefully misleading (or both)
