What is Full-well capacity?
The maximum number of electrons one image-sensor pixel can hold. The larger it is, the brighter the scene can be before highlights clip, widening dynamic range.
Full-well capacity in the explanations
Smaller pixels allow more pixels on the same sensor, but light per pixel falls in proportion to area and the full-well capacity shrinks too.
What problem tends to occur when the pixel size of an image…Full-well capacity is the maximum number of electrons a photodiode can hold; beyond it, highlights clip.
What is the maximum number of electrons that one pixel of a…When light exceeding a pixel's full-well capacity strikes it, excess charge spills into neighbors, spreading bright areas outward—blooming; in CCDs it may also appear as vertical smear streaks along the transfer direction.
