ISO – Beginner Photography
ISO – Learn Photography
ISO is the digital equivalent (or approximation) of film speed. If you remember, back in the day, you will get 100, 200, 400 or 800 ISO. This still applies to digital photography, but it’s called an ISO instead of ASA. It’s still the same, 100 and 200 for outdoors with a lot of light and 400 and 800 for indoors with less light. The same rule that the higher the number, the more light comes in still applies.
General rules for ISO settings
ISO 50, 100, and 200 are the lowest settings depending on the camera. It is for FULL SUNSHINE. (some high-end cameras have 50)
ISO – 400 – overcast cloudy, not so much sun.
ISO – 800 lower light – sunset time and so on.
Digital Noise and ISO
Grain or Digital Noise Examples
Here is an example of grain in a picture. On the left. The stuff on the right is what you will need to edit your photos, and we highly recommend everything we advertise in our magazine. Back to learning; the darker parts of images is where you will see more digital noise or grain. Grain is very common in night photography. Let’s talk about ISO and night shots.
Using ISO at night.
Here is your homework. Look at the ISO settings on your camera and see the different increments. If you have read shutter priority, Set your shutter speed for 1/200th of a second and take a shot at 100, 200, 400, 800 and all the increments to the end. Watch as your picture gets lighter and lighter.
