Tip of the day: ISO
What is ISO?
In film cameras, the ISO refers to how sensitive the film is to light. In a DSLR the same concept applies, but it refers to the sensor setting instead of film.
Basically, the lower the ISO number, then the less sensitive it is to light. If you are out photographing subjects in the bright midday sun, then you will probably want to use the lowest setting available (probably ISO 100 or 200).
Conversely if you are photographing poorly lit scenes then higher ISO settings are in order. Just remember than the higher ISO settings often bring the problem of digital noise (unwanted speckles and spots in your images).
Usually the top end DSLRs are better at handling noise problems at higher ISO settings.
Note: We will be offering these little tips regularly for DSLR, intermediate cameras and smartphone.
