Triangle

APERTURE ISO SHUTTER EXPOSURE PERFECT BALANCE

Every photo is made by balancing three settings. Change one and you'll need to adjust the others to keep the right exposure — how bright or dark your image is.

GO
SHOOT

NOW YOU KNOW

1

Start in Aperture Priority (Av/A) mode — you control depth, camera handles the rest

2

Keep ISO as low as possible — only raise it when you truly need more light

3

Shutter speed below 1/60s? Use a tripod or you'll get camera shake blur

4

The best way to learn is to shoot in Manual mode and experiment daily
