In this series, I will go over how to improve your photography skills and utilize the best settings for your DSLR camera. These recommendations are based on my experiences and learnings. In the first part of this series, I will cover camera modes and which ones to use.
What are digital camera modes?
Simply put, there are letter modes and icon modes.
Letter modes include Program Auto (“P”), Shutter-priority (“S” or “Tv” ), Aperture-priority (“A” or “Av”), and Manual (“M”) on the mode dial. These settings allow for the most creative flexility because you can adjust the aperture, shutter speed and ISO yourself.
Icon modes include the little pictures or icons on the mode dial (i.e. “Sports”, “Portraits”, “Macro”, “Landscape”, and “Night”). The camera predetermines the settings based on which mode you choose. This sounds great, but they don't always work for what you are trying to shoot and they override most of your manual settings. I do not recommend using the icon modes.
What are the differences between the letter modes?
Program Auto allows you to control the ISO and flash. The camera selects the shutter speed and aperture for you. I do not recommend shooting in this mode because you can't control the shutter speed to make sure your picture doesn't come out blurry.
Shutter-priority allows you to control the shutter speed and ISO. The camera selects the aperture for you. Shutter-priority mode can be useful when the shutter speed takes priority over the aperture in order to get a specific effect. For example, when you are trying to get smooth waterfalls, light trails, or capture a fast moving object.
Aperture-priority allows you to control the aperture and ISO. The camera sets the shutter speed for you so it is properly exposed. If you are shooting landscape photography, portraits or sports for example, aperture priority mode works effectively. You can also increase the ISO (i.e. 200 - 1600) to get faster shutter speeds. A higher ISO can increase noise in your photo, but can help with blurring.
Manual allows you to control the aperture, shutter speed and ISO. This gives the photographer total control over the image. Manual mode can be a bit intimidating to work with, but with a bit of experimentation, you can get just what you are looking for. If you are shooting nighttime photography, manual is the way to go.
What camera mode should I use?
It depends on what you are shooting. I recommend “Aperture-priority”mode for portraits, landscape photography, etc.,
“Manual” mode when you need to shoot the same thing repeatedly or situations where you aren't rushed for time, or “Shutter-priority” mode for fast moving objects, like sports photography. In my opinion, it is ok to use “Program Auto” when shooting indoors and you need proper exposure. I use Aperture-priority mode most of the time. Aperture-priority mode works for just about every type of photography, which is why so many professional photographers use it. Overall, your photos will drastically improve if you learn how and when to use P, S, A or M modes.
