I think it would be of a huge use for everyone here, and on the forum in general to have access to a numerically calibrated grey scale card. The most common greyscale card availible is the kodak grey scale card, with 20 non-linear gradations. Most of them will be useless to us, but the card is at least easy to find. I am going to take one to the local university, and have it measured for greyscale numbers, as in %.

It would be best that this be verified by another participant, somewhere else, so it can bee seen that the numbers are accurate enough for our use. Someone please step forward and marrch forth with their greyscale card, please! I am using the larger card, that is about 16" long or so.

KBK,

Sounds great. Do you have a model number for the card(s) you are refering to?

One word of caution - my 18% card has a pinch of gloss to it. I hope this doesn't hurt your readings any.

Going to bring it to Texas A&M, I guess?

The card is the 35.6mm long 'Color separation guides and grey scale (large)', product code Q-14. There is a newer version out, but the grey card SHOULD be identical. Kodak cataloge number '152 7662'. Interestingly enough, they come out of Kodak's 'Graphics Markets Division', which happens to be located in..... Rochester, NY. Perhaps I'll give them a call. See what they have to say. These cards have quite a bit of gloss to them, and it is on each and every one I have set eyes and hands on (about 5 so far).

I don't know much about Texas A&M, except that it is one of the only places on the planet that has a complete, proper, acoustics program availible. I was going to apply there (many years back), but it is a bit too far for me to take the bus back and forth....

I have just been contacted by someone inside the industry... apparently people are paying attention.
