Image Format Picture is compressed to save space Quality:LowHighRaw File Size:2MB4MB20MB Loss of colors Sharpening Loss of detail … but faster!

Multiple Shots Capture unpredictable motion Bracketing exposure High Dynamic Range Short movie clips

Sensitivity ASA or ISO “film speed” Take pictures in low light Increased noise (colored speckles)

Flash Built-in flash can reach 10 feet or so Fill flash is a nice effect Plain flash gives stark shadows Red eye prevention takes time Early flash vs. late flash

Zoom Expressed as 35mm equivalent:  35mm is wide angle  55mm is normal  135mm is short telephoto Old rule of thumb: handhold 200mm at 1/200 th or faster, but stabilization can double that Digital zoom is just in-camera cropping

Self-timer Prop the camera on a level surface You have 10 seconds to run around front and smile Can also be used to start a time exposure.

Filters Used to be used for color adjustment “Skylight” or “1A” used to protect the lens if you have threads Polarizer controls reflections and deepens sky color Some cameras have useless built-in black and white or sepia effects

Special Presets Scenery – locks focus at infinity Portrait – balances for good skin tones Night – optimizes for low light Sports – tries for high shutter speed Smile – Waits for smiles! Etc…
