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.
Physically 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.

Will the supplied S-Hook work as a stand on the larger 3.5 x 6" G7 card?
Asked by: peter
This is not a stand, not that the card needs one. The hook can only be used to attach the card to something so its not lost during the shooting sessions.

Does the letters and markings (like the cross hair marker in the center) on the card affect custom white balance on the camera?
Asked by: Tsehtshau
No. The cross hairs are for centering your camera's center focus point so that you can either fill the majority of your LCD in LiveView or viewfinder or to aim your strobes dead centre on the card. Keep in mind that you need to eye dropper several grey areas of the card to get the best reading to your eyes.

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.

question

Will this card work well for standard portraiture photography (rather than simple macro photography), or should I opt for something bigger?
Asked by: Trevor T.
Spot meter the tiny card and it will work. Obviously, a larger card would be ideal for portraiture photography. I carry two. This one for all unscheduled situations and the 3.5 x 6" for scheduled assignments.

question

Is this an 18% gray?
Asked by: Saul S.
No. The maker states that it is designed as a "Gray Card for Accurate White Balance". It is not for exposure which is the function of your camera's light meter. It is done for colour accuracy.

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: Oliver
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.

question

Is this card appropriate for manually adjusting white balance in camera?
Asked by: Zach I.
Yes. You can use the custom white balance setting in your camera to set the correct WB. It will save you a lot of time in pos processing.
