“Dynamic Range” v. Exposure Value (”EV”)
Posted in Color Science on Apr 24th, 2008
Several questions (mostly from PAPA Members) have come in over my recent reference to the Contrast Ratio of a 32 bit image.
What's going on right now at Idaho Airships, Inc.?

Extreme Contrast Manipulations In Photoshop
Posted in Color Science, Extremely Extreme Photoshop on Apr 15th, 2008
For some time…since about the time I hooked into medium format Portra NC160 (long story as to why)…I’ve been obsessed with extreme contrast imaging.
Camera RAW Clipping Indicators
Posted in Color Science, Extremely Extreme Photoshop on Apr 14th, 2008
Camera RAW 4.4.1 has arrived. We’re shooting 1DsMIII 14 bit files, and I’m starting to feel uncomfortable doing my coarse developing in any other editor.
Color Management in Windows Vista: Push-Starting a Nuclear Reactor
Posted in Color Science, Computing Hardware on Feb 11th, 2008
Windows Color Management is in a sort of adolescence. If you are using Vista and/or in the process of learning Color Management, you’ll need to spend an hour or two here. The relatively small investment of time will pay handsome rewards. Trust me.
18% = 50%: Photographic Exposure and Reflectance
Posted in Color Science on Jan 7th, 2008
An imaging target will present a range of of brighter to darker features-it’s “Luminance Range.” That luminance range is dependent upon two factors: The amount of light available (illuminance), and how much of that ambient light is reflected back to the camera (reflectance).
