- Shutter speed controls how long the sensor is exposed to light. A slower shutter speed will let in more light and a fast one less light. Slow shutter speeds such as 1/15 sec. show motion while fast shutter speeds freeze action.
- Aperture controls how much light is allowed through your lens, and is controlled by f-stops. A bigger aperture (f/1.8) will let in a lot of light and a smaller aperture (f/22) will let in less light.
- ISO is super important and one major difference between film and digital SLRs. It controls how sensitive your camera’s image sensor is to the light. In bright light use a low ISO, in low light you can use a higher ISO. The higher the ISO the more noise (digital grain) will appear in your photo so keep it as low as possible.
- In Program (P), Aperture Priority (A, Av), and Shutter Priority (S, Tv) you are responsible for setting 1 or 2 of the 3 exposure options (ISO, shutter speed, aperture) and your camera takes care of the rest to get you a well exposed photo.
- When your camera is wrong in Program (P), Aperture Priority (A, Av), and Shutter Priority (S, Tv) and gives you an over or underexposed photo you can override its decision with exposure compensation which will allow you to make the photo brighter or darker.
- Manual mode allows you to have complete control over your camera and allows you to set all three aspects of exposure. You make sure you photo is well exposed by using the light meter at the bottom of your viewfinder.
- White balance measures the temperature of light in the scene. It is what is responsible for making sure you don’t get blue pictures when shooting in the shade and orange pictures when shooting in a gym. There are several preset options for white balance but to completely accurate you will need to use a custom white balance tool or a grey card.
- Aperture is the easiest way to affect depth of field. A shallow depth of field is where less of the photo is in focus and is achieved by having an open aperture, ie f/1.4. A deep depth of field is where more of the photo is in focus and is achieved by having a smaller aperture, ie f/16.
- Flash can be a lifesaver! While I don’t recommend the pop-up flash that is built into your camera, an external flash can really step up your photo game, no matter what kind of photography you do.
10. Select the correct focus mode for your camera. Know whether you want to be using single point, continuous, or manual focus . to help you achieve the shot you want.
