How is exposure made when you take a picture?

Exposure is the result of three different variables that determine if your photo is under-exposed (too dark), over-exposed (too bright), or evenly exposed. The three variables that make up exposure are Sensitivity, Shutter Speed, and Aperture.

What is exposure in a study?

The exposure refers to any characteristic that may explain or predict the presence of a study outcome. The outcome refers to the characteristic that is being predicted.

What is ascertainment of exposure?

Ascertainment bias can happen when there is more intense surveillance or screening for outcomes among exposed individuals than among unexposed individuals, or differential recording of outcomes.

How do you control exposure?

What’s the difference between ISO and exposure?

iso is the sensor’s sensativity to light. by going up from 100iso to 200 to 400 etc the sensativity increases. exposure is the amount of light that the sensor receives during each shot. the amount of light can be varied by changing the fstop and/or the shutter speed.
