VidCon 2016 may be over, but we bring you 17 of the best tips we picked up from the Creator and Industry Track seminars at this year's event.
In photography, exposure is the amount of light allowed to fall on each area unit of a photographic medium (photographic film or image sensor) during the process of taking a photograph. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region. Exposure is the amount of light that you allow to hit an object or area in a photograph. This can convey a certain message or mood in one’s picture.
In photographic jargon, an exposure generally refers to a single shutter cycle. For example: a long exposure refers to a single, protracted shutter cycle to capture enough low-intensity light, whereas a multiple exposure involves a series of relatively brief shutter cycles; effectively layering a series of photographs in one image. For the same film speed, the accumulated photometric exposure (Hv) should be similar in both cases.
Photometric or luminous exposure Hv is the accumulated physical quantity of visible light energy …
