Exposure - tradeoffs

Aperture

•smaller opening greater depth of fieldeld

•larger opening shallow depth of fieldld

Shutter Speed

•slower camera movement causes blurlur

•faster shutter “freezes” action (no blurlur))

Film Speed

•faster (larger ISO#) coarser grain

•slower (smaller ISO#) finer grain

Depth of Field

Depth of Field

Depth of Field and Exposure

Aperture

•smaller opening (larger f/#) lessss lightlight

BUT greater depth of field

Need maximum depth of field for macroacro (close-up) photography

Need high-intensity illumination sourcesource
