• 640x480 = 307,200 pixels (0.3 megapixels)

• 2048x1600 = 3,276,800 pixels (3.3 megapixels)

– The higher the resolution, the LARGER the digital photograph!

Camera Types – con’t• Quality Settings

– Economy• Low quality – Good for distance or general

outdoor• Small file size (lots of pictures fit in memory)

– Standard• Medium quality – Good for mid-range shots,

group shots• Average file size (fewer pictures fit in memory)

– Fine• Best Quality – Good for people and detail work• Larger file size (fewest pictures fit in memory)

Camera Types – con’t• You can change resolution

and/or quality ‘on the fly’– Mix and match resolution on

Digital Film

• The MORE memory, the MORE pictures!• Pay attention to the type of memory your

camera requires!• Extra memory cards will keep you

shooting!• The MORE memory you have, the MORE

pictures you can take at a time!

Taking Digital Pictures• Know your camera! Read the manual.• Save the fancy stuff for the photo editor!

– Whatever your original pictures look like is what you have to START with!

• Digital Zoom vs. Optical Zoom– Optical is ALWAYS better!– Digital will create ‘blocks’ in your

photos

Taking Digital Pictures – con’t

• Watch the lighting and the FLASH!– Digital cameras can usually adjust for low light– Built-in flash is good for 5-10 feet only– Your camera may have ISO settings

• The higher the ISO, the more light your camera lets in.

• Too high of ISO will lead to ‘dotty’ overexposed photos! (200 speed is good for most applications)

Taking Digital Pictures• OOPPPSS! I Did It Again!

– Digital cameras allow you to deleted unwanted pictures immediately!

– New pictures are taken ‘after’ pictures already stored on the memory card. (no ‘gap-filling’)

– If you have the space, take 2-3 pictures every time. Then, delete the ones you don’t like!
