•It’s not the total number of pixels that matter but rather the number of pixels per inch an image has when printed at a certain size.

Resolution and Print Size

• Viewing on monitor/web: Resolution of 72 ppi• Pro. quality printing: Resolution of 300 ppi• To figure out what size print at 300 ppi print

your camera can make, divide the pixel length and width by 300.

• 15MP camera, large jpeg = 4752 x 3168 pixels• This equals to a 15.8” x 10.5” print without

cropping.• 300 ppi is a recommendation (240 ppi min.)

ResolutionWeb images – 72ppi (pixels per inch)Ideal for Printing – 300ppi (pixels per inch)

Mechanics of a Camera (SLR)

Reflex refers to the way light travels from the subject to the viewfinder. Light comes through the lens and is reflected up by a mirror to a focusing screen that is found just below the camera viewfinder.

A groundglass is located at the base of the pentaprism. The pentaprism is a box of mirrors which correct the image so that you see the scene as it looks to the eye. Without the pentaprism the scene would appear upside down in the viewfinder.
