1) What’s Shutter Speed and Why Does It Matter?
Shutter speed measures the length of time that the shutter stays open to let light through the aperture and fall on the sensor that records your image. It’s like opening and closing the blinds to let light in—or keep it out.
Whenever you take a photo, the camera performs two functions:
2) It opens up the aperture to the correct size for that exposure
b) It removes the cover from in front of the sensor to allow light to reach it.
Once the exposure time is completed, the camera moves the shutter back in front of the sensor, blocking more light from reaching it.
Yes, your camera comes with a built-in flash. But that doesn’t mean you should always use it…even if your camera wants you to blind some unsuspecting person with it.
If you want to take great pics (and of course you do, or you wouldn’t be reading this!) there’s three fundamental principles you must get right. If you fail at any of these, you’ll be disappointed with your results.
The Three Pillars of Photographic Excellence Are:
Read on for tips on how to take better photos by understanding these three principles and applying them to your next photo session.
Modern cameras are very smart, but it doesn’t mean they’re always smarter than you are. That’s why it’s important to learn about the exposure compensation feature of your DSLR. Even less expensive point-and-shoot model cameras are getting into the act and adding this essential feature, so let’s learn more about it.
Having an exposure compensation setting on your camera means you have the ability to make an adjustment to the exposure of your photos in mere seconds.
This handy function is often identified by a small icon, usually similar to this :
Exposure Compensation allows you to slightly adjust the camera’s choice for the exposure, by telling the camera to allow more or less light in. But you might be wondering why you’d ever need to use it if you’re shooting in automatic mode?
1) What is an Aperture?
The aperture is an opening (a hole or a gap) formed inside the camera lens by the blades of the shutter. A camera aperture works much like the iris of the eye, widening or constricting to control the amount of light hitting the light sensor. The aperture setting controls how much light can enter the camera at a given setting.
