Mrs. O Talks Aperture, ISO & WB!)

• Biggest to smallest f/stops, f/22, f/16, f/11, f/8, f/5.6, f/4, f/2, f/1.8
• The bigger the number the smaller the hole.
• The smaller the number the bigger the hole.
• Shallow Focus: f/1.8, f/2, f/4, f/5.6
• Deep depth of field: f/8, f/11, f/16, f/22
• With a depth of field foreground, middle-ground, and background are all in focus.
• With shallow focus, the foreground, middle-ground, and background are out of focus.
• With shallow focus, the subject is in focus.
• ISO 12,000 – 50
• In dark environments, a higher ISO is sometimes required. 800 through 1600 is optimal.
• In normal environments light ISO stays at about 400.

Photography Basics: What Is White Balance)

• White balance is how the camera controls color.
• In photography, color is measured by temperature.
• Auto white balance in cameras have to measure the temperature in the scenery and attempt to match it.
• When a scenery’s temperature/color is off, you can manually change your white balance.
• The higher the number the warmer the temperature/color.
• The lower the number the cooler the temperature/color.

What is ISO? Photography Tutorial: ISO Made Easy)

• ISO is the sensitivity of the camera to light.
• The higher your ISO the more sensitive your camera is, in turn, less light is needed.
• The lower your ISO the least sensitive your camera is, in turn, more light is needed.
• Aperture controls depth of field.
• Shutter speed controls movement.
• ISO controls aperture and (mostly) shutter speed.
• The higher the ISO the higher your shutter speed.
• Significantly high ISO can create a lot of noise/grain in your photo.
