What I learned about exposure

Exposure is how bright or dark a photo is.

The exposure triangle consists of the aperture, ISO and shutter speed.

Being able to use all 3 perfectly can lead to great photos.

All 3 components work together.

The aperture controls how much light enters through a whole in the camera lens.

The shutter speed controls the timing of the exposure.

The ISO speed controls the cameras sensitivity to light.

Aperture affects the depth of field.

Shutter speed affects the motion blur.

ISO speed affects the image noise (too much will cause a grain effect)

The faster the shutter speed is means the exposure time is shorter.

A slower shutter speed is good for photos at night. (1 -30+ seconds)

A faster shutter speed is best for fast moving objects (like players in sports)

If you have proper focus on a photo and it comes out blurry, then you should increase shutter speed or use a tripod.

The different values for aperture setting is called “f-stop”.

As the f-stop decreases, the area of the camera lens hole opening increases.

When you say “stopping down” or “opening up” your lens, you are referring to increasing or decreasing the f-stop value.

The range of values vary from different cameras.

Having a greater range of values is better for creative flexibility.

The depth of field is the range of distance over objects appear in sharp focus.

It is good to have a low f-stop number for a shallow depth of field.

It is good to have a high f-stop number for a larger depth of field.

The ISO speed is very important because it can dramatically increase the noise of an image.

High ISO speed will create a grain effect over a photo. (I personally like how it looks)

Different cameras vary with ISO speeds.

The different camera exposure modes are Auto, Program, Aperture priority, shutter priority, manual, and bulb.

Each mode is used for different settings. (You would wanna use sports mode for sports obviously, it will make the shutter speed very high.)
