- Auto — everything is on auto, including ISO, flash and image quality
- Portrait — uses a large aperture to shorten the depth of field
- Landscape — uses a small aperture to gain more depth of field
- Sport — uses higher ISO to use faster shutter speeds
- Night portrait — uses long exposures to capture the entire scene, often combined with built in flash
- Macro — uses a large aperture to great a softer background
Just Say NO! to Automatic Modes
There is no reason what so ever to use the automatic modes. After you’ve read through this series of articles about photography you should have enough knowledge to control the camera on manual modes — which will result in better photographs.
The Program mode (P) is fine to use, this way you will have the aperture and shutter automatic but still be in control over everything else. Most photographers find a mode that they like and maybe switches between two different modes, this is personal preferences and let me just tell you that far from every professional photographers uses only the fully Manual setting.
I personally use M and Av most of the time, depending on the situation. Av for the situations where I don’t have enough time to set the correct exposure between every shot and then M for the rest.
I usually shoot (perhaps about 80% of my photos) in the Av mode since I use only RAW and I can do some PP if my camera picked a bad shutter speed… and since I have a Canon 40D that’s not the frequent case! Anyway, If I find myself compensating (EV +/-) exposure too often, then I change to M … you need the Av mode if you can’t corrext exposure between every shot, for example if you are taking photographies of (wild) children!
Did you think this cute girl of two years old would wait for me to prepare the perfect shot? I think these shots took me about 2 hours!
