If you set the AF-C and the AF-S priority to Release, this will enable you to take photos irrespective of focus/color/contrast. These settings are accessed by Menu/Custom Settings/Autofocus/a1 AF-C priority and Menu/Custom Settings/Autofocus/a2 AF-S priority. They should both be set to Release. It is all on page 231 of the D7100 User Manual (p.259 of the ...

The obvious bottom line is about CCD sensors. CCD sensors can be used as shutters. CCD has to be disabled each frame to transfer the image out of it anyway, so they can simply time the enabled time as a shutter. Inexpensive cameras (compacts and camcorders, and less expensive DSLR too, back in the older days) still use CCD sensors for the free shutter. ...

Yes, digital cameras with focal plane shutters generally move vertically across the film plane. In contrast, most 35mm film cameras with focal plane shutters moved horizontally. The unexposed film came from a roll at left, and exposed film spooled up at right. The mechanical system to cock the shutter was simpler and smaller when that cocking motion was ...

The overwhelming majority of modern cameras with focal plane shutters go from the top to the bottom in the light box. Since the image projected by the lens onto the sensor is inverted, this means the landscape picture you view later was exposed from the bottom to the top. With portrait orientation all bets are off, since it depends on which way the ...

Rolling shutter looks like the most obvious answer but I'd say it is a red herring. With rolling shutter the cyclists would not be cut in half as they are, they would be bent or warped through their full length, all of which would be in the frame. As would other objects in the frame. The wheels would also show signs of extreme geometric distortion in the ...

This is due to the "rolling shutter" effect. See this video for a somewhat nauseating example, or this description with great graphics. Basically, at this exposure setting, not all the image is scanned in one instant, but rather in stripes, so that the bicyclist was not in the frame for the whole duration (though the background, farther away, was visible ...

The camera needs a specific amount of light to take a properly exposed picture. How much light hits the sensor is tied to two items: shutter speed and aperture. Shutter speed defines how long light hits the sensor and aperture defines how much light hits per unit of time. If you want to avoid blurry images you have to set a fast shutter speed as you've ...
