Spectrally neutral--reflects all colors through the spectrum equally. The G7 Reference Card has both *a and *b Lab channel values of less than 1 at D50 and are spectrally "flat". It's spec'd at less than +/- 0.5.
Maintains its spectral neutrality under all reasonable temperature and environmental conditions.
Rugged--waterproof and scratchproof (color goes all the way through, not just a coating on top).
Does not respond to UV light any differently than the visible spectrum.
Each card is individually measured with a precision spectrophotometer to certify that it meets or exceeds stringent specifications.
Designed for low reflectivity, except that the sticker is intentionally highly reflective so that maximum TrueBlack Blackpoint level may be achieved by observing for maximum glare point.
Can be used to set white balance reference, Black point and White point.

This card is the best if you are wanting great white balance for your color images. I usually put the light meter on spot metering and take a shot and then shade the card and make a second shot before i start shooting landscapes. And redo the same every 30 minuets to an hour. I haven’t tried it with color film yet, i mostly shoot black and white on film.

Does this fit in the credit card slot of a wallet?
Asked by: Kerrick
Yes, it will fit "most" wallets. Some wallets have smaller credit card slots which is beyond me.

Why is it so small??
Asked by: Lee
All you need for white balance measurement is a small spot - and this card is perfect! Also - It's called a White Balance "Pocket Card" because it small enough to carry around.

question

My canon xti 400D says to use a sheet of white paper. Will this enhance my white balance even more or throw it off since it's gray?
Asked by: MO
In Live View and with the Histogram active on your camera's LCD, aim and move the camera over the white surface (i.e. wall, etc) until the collection of graphical vertical bars are in the centre of the histogram. The tighter the width along the x-axis of the group of bars the closer your reading will be to a true grey card. This method may take more time, but try it if you don't have a grey card handy. If you do have a grey card, take it to your paint store and grab a couple of free flat or eggshell finished paint chip cards matching the grey card and keep it in your wallet or camera bag for emergency use. By all means, buy the WhiBal reference card which is as close to accuracy as one can achieve. I have the 3.5 x 6" version and it works for my purposes.
