[REVIEW:] Delta 1 18% Gray Card – Matthew Robertson (thewsreviews)

Visited 29 times, 1 so far today

This cardboard grey card is marketed by Delta 1, a company out of Dallas, Texas. Their website is a little short on details; apparently the page for the grey card didn’t make the transition over from Geocities. But the packaging comes to the rescue, saying that it has a reflectance of 18% (+/-1%) ‘on which all external and internal light meters are calibrated.’ There’s more here by Thom, which is interesting reading if you’re planning on using these for their stated purpose: getting accurate exposures.   — Matthew Robertson
