Essential Photography Concepts

Focal Length

• Distance from lens to sensor, affects magnification

• The thickness of the lens

• The curvature of the lens surface

• The type of lens material used

Aperture

• Controls light entry, affects depth of field

• Determines the camera's shutter speed

• Adjusts the ISO sensitivity

• Modifies the lens focal length

Exposure

• Combination of aperture, shutter speed, ISO

• Only the aperture setting

• Only the shutter speed setting

• Only the ISO setting

Bokeh

• Blur quality in out-of-focus areas

• A type of camera lens

• A photography technique for lighting

• A style of portrait photography

Rule of Thirds

• Composition guideline for balanced images

• A technique for adjusting exposure

• A method for color correction

• A style of portrait photography

Shutter Speed

• Duration shutter is open, affects motion blur

• The speed at which a camera processes images

• The amount of light entering the camera

• The resolution of the image captured

Depth of Field

• Zone of sharp focus in an image

• The distance between the nearest and farthest objects in a scene

• The amount of light that enters the camera

• The angle of view of the camera lens

White Balance

• Adjusts colors to match light source

• Increases image brightness

• Reduces image noise

• Enhances color saturation

ISO

• Sensor sensitivity to light, affects noise

• A measure of image resolution

• The type of lens used in photography

• A standard for digital file formats

HDR

• High Dynamic Range, combines multiple exposures

• High Definition Resolution, enhances color depth

• High Dynamic Resolution, increases frame rate

• High Data Rate, improves streaming quality
