AllJorj Takacs Thank you for the responses so far, but this gray card i lighter than the normal gray card. And, they say it's just for "digital" cameras. It thought that gray cards represented an average scene, what difference does it make if your metering with a film camera or a digital camera. Average is average! Ah - I think its as trevor suggested, more for making an accurate white balance than for exposures, that's why it wouldn't work for a film camera. In film photography we know a grey card to be 18% grey with often a colour bias (from production) - the colour isn't a problem for film as much as it is important to have an accurate density for digital white balance readings, colour accuracy is more important that density. it's a good idea really to use a grey card for a white balance over a white card - it's been argued that a white card is more likely to yield an overexposed reading.. and an overexposure tends to be white, irrespective of slight colour variations this make sense? karl
