Weight and Stuff Report – 27 September 2015

Back up again today, mutter. Or perhaps it is the scale having fun with me again…

I went out today to give the iPhone 6S camera a bit of a test. Results were, as expected, mixed. When taking sensibly lit shots like this, it does rather well:

The traditional wide view

Camera: iPhone 6s
Aperture: ƒ/2.2
Shutter speed: 1/1700s
Focal length: 4.15mm
ISO: 25
Taken: 27 September, 2015
Location: 54° 58.187′ 0″ N 1° 35.9542′ 0″ W

No tweaking done to the image other than a slight crop.

But if you do sill things like shooting in the direction of the sun, it gets a bit confused. I’ve mentioned before that getting a good exposure in Central Arcade can be tricky, as on a bright day most cameras will attempt to compensate for the bright roof. The iPhone 6S is no exception, as this example shows:

Overwhelmed by light

To the eye, the interior was quite bright, but the phone has rendered it in deep gloom. That’s because (like most sensors) it’s assuming that most things are fairly neutral in brightness, so that glass roof can’t possibly be that bright, and so it’s reduced the overall brightness. Now with my X-T1 or X100T, I’d be able to fix this easily by editing the raw file, but all I had to play with this time was a JPG, but I’ve managed to pull some detail out of it:

More playing will no doubt follow…
