Definition posted: Flash; Pop-up Flash

When using the ‘auto’ mode the on-board light meter in a DSLR is set to trigger the pop-up flash. It will spring up when the light conditions are too low for an optimal exposure to be created. After this the flash will fire each time the picture would under-expose without it. Today we have put a new entry to cover this in the Photographic Glossary. See: Pop-up Flash; “Cobra” Flash; Flip-up Flash.
