[Nhcoll-l] Micro color chips

[Paul Callomon]

Folks,

I am taking photographs at high magnifications (4-5x macro; field size roughly 6x4 mm) and would like to insert a calibrated grey chip for accurate color reproduction. Commercially available chips I have seen are all printed on paper or plastic, and at those magnifications the ink surface is so rough that one cannot accurately sample the color from it any more. Does anyone know of a color chip specifically designed for macro/micro work?
