• Having two identical cameras spaced apart (to generate parallax) allows you to computationally generate an image equivalent to if the photo were shot with a bigger (heavier, more expensive) single lens. Most notably, this allows blurring the background for more pleasing portraits. I've got huge 70-200mm f/2.8 lens on my DSLR for this purpose. You do NOT want something that big stuck to your phone.
• Prime lenses (single focal length optics) have superior image quality to zooms. Primes are also less complex to design optically, resulting in a smaller lens.

So having two wide-angle cameras and two telephoto cameras on your phone duplicates a single big professional-quality zoom with a large aperture, but without the weight and expense. Unlike the display PPI war, the reason for these extra cameras is functional.

However, I didn't make the comment since this was only a single incident... until you reminded me that this is the second such incident of a mentally unstable Youtuber going on a murder suicide when they lost their income stream.

Seems to happen with some regularity in Hollywood that someone famous ODs when faced with the prospect of diminishing opportunities to earn the revenue stream they've become accustomed to.

It's probably really difficult for these types of people to accept working a "regular" job for a pittance, in much the same way I'd imagine most of us would lose our shit if we were faced with the possibility of swapping lives with a Chinese factory worker.

Realistically speaking, this guy was never likely to find something else which paid the amount of money he was making. That said, it still doesn't excuse the murderous part of his suicide.

I'd agree Hollywood has partially the same issue though I don't think the problem is quite as extreme, in Hollywood the talent tends to be a bit more stable and the downfall tends to be a bit slower and softer.

Internet "entrepreneur" shocked that people believe their work has value, and shouldn't be stolen:

that is a VERY nice looking piece of kit. http://www.diyphotography.net/...

The human retina actually does some pre-processing before the pixel data (input from rods and cones) goes further along the visual circuits. One of the most basic tasks is edge enhancement and based on red-green, blue-yellow and intensity values based on a large sample of input data:

In image processing speak, these are called edge detection and contrast detection. If there is an intensity difference between two areas, then one is darker than the other, and vice versa. This difference gets amplified close to the border between the two edges. So the human eye can immediately tell there is some kind of edge. For the application of painting, having a split view would allow the artist to immediately tell when the source color (the scene) and the destination color (the painting) matched. Professional cameras use a similar mechanism for perfecting focus:

So the artist could just start off with a very basic poster paint color scheme, then gradually add the shadows and the highlights.

Canon's actually pretty cool about the use of custom firmware. Plus projects like CHDK and Magic Lantern (and the thing that hacked the 300D into something fancier) have been around for quite a few years, and Canon hasn't tried squashing them.

(Although apparently their hacker-friendly nature most definitely stops when it comes to the EOS-1 line.)

Yes, it does apply. Laser light is subject to the inverse square law like any other light.

Not according to posts (below), summarizing:

The inverse square law applies to light radiated in all directions. The reduction in intensity is because the same amount of light is covering an ever expanding area. With a laser, you're sending the light in a straight line (theoretically, at least). The light beam covers the same amount of area 10 miles from its source as it did when it first left the laser.

The inverse square law applies only to isotropic light sources. A laser is highly directional and thus does not obey the inverse square law.
