Lower the light, the higher the ISO

Ranges from 100-3200 ISO or higher

Determining Exposure

1. Adjust ISO for lighting conditionTry to keep ISO as low as possible, prevent grain/noise

Higher ISO’s will allow for faster shutter speeds

2. Shutter Speed and ApertureCombine aperture (f-stop) and shutter speed for correct exposure

Equivalent Exposures

Equivalent Exposures

Changing both aperture and shutter speed in opposite directions to create the same tonal exposure

Changing both aperture and shutter speed in opposite directions to create the same tonal exposure

Allows for creative decisions

Equivalent Exposures

1/3 stops

Bracketing

Changing one of the three manual settings, with the other two remain constant.

Ex. Aperture changes - Shutter Speed and ISO stay the same

Any manual setting can be bracketed

Bracketing

Allows for more options when editing

A good habit to start, great for tough lighting situations
