Some of you older darkroom folks who used to print color, and older photogs who shot medium format color negative or transparencies surely must remember the macbeth color chart? This remains a very useful tool on location or in the studio or wherever. For those of you who feel more comfortable just shooting with auto white balance DSLR nikon cam settings, the color chart helps immensely in post-processing when trying to match the colors accurately from different nikon camera bodies. Remember the days when shooting color neg, we simply placed the macbeth chart in the frame of the shot, made one exposure under the lighting we were using, and then pulled the card for the remainder of the shoot. Once the negs were developed, it was easy to use the macbeth chart in the image frame to set ballpark color-filter settings on the enlarger. The 'old' macbeth chart (8.5x11 inches - roughly the same 35mm aspect ratio for still and cine) remains available: http://www.filmtools.com/maccol.html?gclid=CIbippm0o7oCFQZyQgodlnsAnA You can also get the chart from x-rite through adorama. If you are going to use the macbeth chart, you also should buy grey and white reference cards to standardize your manual preset white balance settings. But mount all these cards on larger 4-ply museum quality mattboards to keep the cards from bending and warping.
