Another question got me thinking about what is limiting dynamic range in digital cameras. From my understanding the precision of the analogue-to-digital converter, i.e. how many discrete levels it can ...
For a given film type, shutter speed and aperture, how do I calculate the light needed to get a good exposure? For example, if I use a f/8 aperture, an exposure time of 100 ms and a ISO 800-film ...
Is there such a thing as a maximum aperture that a lens can be open to? What about a minimum aperture that it can be closed to? Do these concepts even make any sense? Is there a lens with the ...
So (without limitations of the viewfinder for example) looking through the viewfinder creates a brighter image than normal view would be. The lens would then work like a funnel(collects light from ...
Solid explanation behind the physics of the relation between aperture size and depth of field [duplicate]
Possible Duplicate: Technically, why is the out of focus area blurred more when using a bigger aperture? Many of us know that there is a relationship between the aperture size (f-stop) and ...
When I take photographs of a subject reflected by a surface (water, mirror, glass) I notice that the focussing distance is not the distance from my camera to the surface, but mostly it is close to ...
Possible Duplicates: What exactly determines depth of field? Technically, why is the out of focus area blurred more when using a bigger aperture? It is obvious that the aperture affects ...
Assuming that camera manufacturers can eventually make the perfect sensor that introduces no electrical noise to the signal, at what point (measured in ISO/area of a pixel) will shot noise be so ...
