comment Why are mirrorless cameras much slower than DSLRs?
I too would like some data on that. Several times I've put my Canon DSLR camera away for several weeks and left it on, and when I took another photo it was ready to go instantly and still with full battery.

comment Is vector photography possible?
@JamesSnell: The mathematical models have never been the limitation. You're never going to be a able to build a camera that could take a picture of the whole earth with down to the atom resolution, but there is nothing mathematically preventing you from representing such an image. This whole question suffers from a misunderstanding of the purposes of raster vs vector graphics.

comment How many “MegaPixels” can the human eye see?
The 'limits' that you think are obvious aren't even remotely obvious. For one, our eyes and brains do not have frames per second. Secondly, we ultimately see with our brains, not with our eyes, further complicating the issue.

comment Is it possible to map temperature values to RGB values in a near-infrared image?
Everything above absolute zero is glowing. As @MichaelNielsen alluded to, only a small amount is in the visible specturm.

comment Why is my ISO so high in auto mode?
What lens were you using and what focal length was it at?

comment Why are tripod legs and heads sold separately? Why no 1-piece tripods?
that's pretty much it, but let a moderator delete it, because someone else might have this question too.

comment Why do cameras use a single exposure rather than integrating across many very quick reads?
@wiso: you will get nearly the same thing. You'll have a little, difference, but not a whole lot. If you compare the difference between the two pictures, you'll find the temperature noise to be quite small compared to the rest of the noise present in the image.

HDR isn't really the same as what the OP is asking about, because HDR is selective in how it combines the information, as opposed to a straight integration. A camera as the OP is describing it would essentially be a device that does a 2D measure of the scene's radiant flux, a measuring of rate, and a photograph from it would be an integration of a set of its data, a display of quantity.

@wiso: temperature related noise is only one source of noise. The significant factor of noise for typical digital cameras is in reading the sensor and signal amplification, which don't depend on shutter speed.

The amount of noise will be roughly the same for a long or a short exposure, which for the multiple-exposure, will be integrated again and again resulting in a poor, noisy final result.

To build on what mattdm said: You can theoretically combine exposures, the data is there. The problem is that for very short exposures, with real sensors, the data is masked by an enormous amount of noise relative to the signal, and your resulting picture will be very meh. Better sensors with a more suitable SNR at the short exposure times would make the concept in the OP feasible.

comment How can I crop a single layer in Photoshop?
resizing the layer is not going to do you any good if it makes that layer out of scale with stuff in the other layers.

-1, You can't use the crop tool, but you sure can crop a single layer.
