Photography Tips and Tricks!

[UncleChester]

Hi there, nice work again. This here is my only objection (and I admit to being picky):

... Theoretically speaking, a high ISO is always preferential because it allows you to shoot with less light available....[/IMG]

Noise issues aside, sometimes it is desirable to have less sensitivity, for example when you want a long shutter to show the effects of movement (e.g. water fall in a vivarium-pretty ghetto pic attached but you can see the waters movement in the fountain part) and you don't want to stop down the lens any more (or can't) and you don't have or want to use ND filters.

It's also handy to have a lower ISO when balancing flash and sunlight for wild froggies. Lower sensitivity will also help you shoot at a wider aperture in full sunlight for an out of focus background, but this has never come up for me as an issue when photographing frogs or other small critters outside, except when balancing with a flash a being limited by the sync speeds.
