Originally posted by raider I checked out the black cat exposure guide and I think it is quite good. But is the USD19.95 inclusive of just the rotating wheel thingy or contains some other documentations, info, booklet, etc?
Okay, here is what mine came with. First is the exposure guide itself. This is thick laminated cardboard page folded in thirds. When open fully, it's about the size of a standard sheet of paper turned sideways (not quite as tall as the sheet sideways and a little wider). When folded, the cover has the rotating wheel and the back has a 18% gray card (useful for metering or setting WB).
The wheel itself has A-Z representing the various scenes. Over that is the first rotating wheel with the ISO setting. You align the ISO with the letter representing the scene of your choosing. Over that is another wheel with the shutter speed you've chosen. Rotating that will expose the aperture. You now have the three settings needed for your scene - ISO, shutter speed, and aperture. You can further move the dials to discover various ISO, shutter speed, and aperture settings that will work with your particular scene.
The rest of the guide contains a list of scenes with the corresponding letter (A-Z) used on the wheel. Each scene contains a description and notes for that scene. For example, the first one is "airplane" with a note saying the interior and also applies to similar interiors like a bus or train. The next scene on the chart is "average scene" and note "in full sun." An additional note here says a "front-lit scene or subject in full sun 2 hrs after sunrise and 2 hrs before sunset." The chart goes on to list dozens of scenes with various notes, with the letters used for the exposure wheel on the cover.
The list of scenes is quite complete, covering everything from full sunlight to swimming pools. In all that are store windows, nightclubs, skylines at night, fog, fireworks ground, fireworks aerial, candle light, museums, snow, moon, moonlit scenes, rain, stained glass inside, stained glass outside, television, christmas tree (singular), christmas trees (plural), and so on.
In addition to the exposure guide itself, the package comes with a smaller two-fold "manual" that quickly explains the exposure guide, gives a couple of examples, and explains the use of the gray card. Finally, the third sheet is an addendum listing additional scenes not covered in the exposure guide.
It's fairly easy to use and accurate most of the time. You'll have to make some judgements calls. For example, in the "airplane" example above (intended for the entire plane interior), the settings may not be ideal for a person on an airplane sitting next to a bright window. In this case, it may be better to use the "window light" settings instead of the "airplane" settings.
Well, that's it. I put the entire package in a standard business-size envelope, which was than tossed into the mesh pocket on the lid of my camera bag. The pocket guides listed also contain much of the same info, but not as quickly accessed. However, the pocket guides also cover notes about cameras, lenses, special techniques, shooting advice, and more.
