comment Field of view of a webcam
It turned out that the given field of view does only apply for higher resolutions, when I open the C310 device to capture 320 x 240 (like Skype did in my first test) it changes it's field of view. I guess the reasoning was to get a better resolution on the subject which is assumed to be in the middle.

comment Field of view of a webcam
The focal length given in the datasheets I linked confuses me as well.

comment what does lens correction in photo software do?
The introduction at the top of the page says: For example, a calibration based on a 1.5x sensor can be used on a 1.6x sensor but not on a 1.0x sensor.

comment Is there such a thing as a filter for circularly polarized light for photographic use, and what would be the effect of using one?
As the plate works both ways, any linear polarized light will be converted to circular polarized light, which is not affected by the linear polarization filter in any angle-dependent way.

Yes, it's that simple, see upload.wikimedia.org/wikipedia/commons/thumb/0/09/… And in general, don't try to look at polarization as a movement that can be frozen by having a very short shutter speed, it just doesn't work that way. :)

revised Why would you want to take pictures without a memory card in your camera?
This question is about everything the technique tag says it is *not*.

comment Is it possible to make “Protected” the default state for new images on my Nikon D3000?
The D3000 was almost EOL when the WORM cards came out and there are no firmware upgrades available for that camera, so are you really sure it will work with the WORM card?

comment How do you use the Depth of Field Preview button on a Nikon D90?
Where does the "very clunky sound" come from? My Canon kit lens only makes a faint "ssst" when it closes the aperture.
