Wesley's Tool-Box

It is pretty safe to assume that the latest iPhone has the best camera in general. The tradition continues with iPhone 7, which allows me to take impressive photos like the one you see here. But to truly appreciate the improvements, a good round of comparison is in order.

First, let's look at the basic specifications as reported by the EXIF data. For the rear camera, we have these values:

And for the front camera:
Last year's rear camera was mostly about the increased pixel count; with the quality improvement taking a back seat. Front camera did jump out of the 1.2-megapixel hole, which was overdue. This year, enhancing the image quality is back in focus. The sensor can now capture on a much wider colour space (DCI-P3, a.k.a. Display-P3, instead of the traditional sRGB), and the wider aperture on the new rear lens (f/1.8, up from f/2.2) should allow for lower noise and brighter night shots. Meanwhile, the front camera can now take 7-megapixel photos.

With major tasks at the workplace wrapped up, I decided that the National Foundation Day holiday would be a good time to upgrade the Mac mini server from El Capitan (OS X 10.11) to Sierra (OS X macOS 10.12). For a warm-up, I upgraded the MySQL Server installation from 5.6 to 5.7 before that, but I ran into some weird issues and took about an hour to resolve. After getting MySQL to work again, I made a full system backup and installed Sierra. With the new OS in place, I restored the server configuration and now you see that the website is back in action. iPhone 7 review will resume shortly.
