Optionally select a NEW EV or EV COMPENSATION (includes one-EV zone descriptions esp. for DIGITAL cameras metering properly to 18% reflectance grey card):
POSSIBLE FUTURE EXPANDED OPTIONS:
Anchor shutter setting to middle
Use FULL stops.
Use HALF stops.
Use THIRD stops.
Use DIFFERENT CHART - SWAP APERTURE with ISO settings to pair ISO with shutter settings.
Use DIFFERENT CHART - SWAP SHUTTER with ISO settings to pair ISO with aperture settings.
Customize for LARGER or SMALLER range of ISO's, f-stops, and/or shutter speeds to match your camera(s).
Customize for in-camera SPOT METER. Average values, and check them against the usable dynamic ranges for various ISO's you enter.
Change the spacing between lines and/or scroll area size.
POTENTIAL USES OF THE CALCULATOR:
- Set two cameras to different exposure settings but the same overall EV setting.
- Set the exposure settings of a film camera without relying solely on metering.
- Get a sense of how digital (and some film) cameras display a final image via a zone scale.
-- Note that the author however recommends using his methods over a (more complex) digital zone system specifically for capturing the image.
