Photography tips for ISO.
Your camera can be a great educational tool for learning ISO. “Set the camera to auto ISO and look back at your work to see what ISO was recorded,” photographer Stephen Klise suggests. “It will help you understand the relationship between real-life situations and ISO.”
While graininess is sometimes used as an artistic effect in photography, lower ISO values will give you less noise or grain on your final image, which is typically ideal. “You want your ISO to be as low as possible while still freezing the action, even if you want some grain for stylistic reasons,” photographer Derek Boyd explains. “The lower the ISO, the more detailed the photo.”
But just because your camera can shoot at ISO 50 doesn’t mean you should do that all the time — experiment to select the ISO for each situation that achieves the level of clarity or grain you want. While a stationary subject and use of a tripod can help capture clear, low-noise photos in a dark setting, when shooting handheld with low light, increasing shutter speed with high ISOs can help reduce digital noise if you want less grain. In well-lit scenes, you can close your aperture down a bit more to increase clarity in your photo.
Experience will be your best teacher, but you can learn more about shooting in different situations from professional photographers. Check out a few of these specialized scenarios below.
With events that often require shooting in bright outdoor light and dim indoor settings within just a few hours, understanding how to adapt your ISO to new lighting is essential.
