Set of two cards for a recalibration perfect exposure and balance of color,

 with high quality of gray Mennon cards  with the spectral reflectance uniform,

regardless of wavelength, color or intensity lighting.

Each card it has two sides:

one side white and the other is gray in color. 

The gray side used as reference area for exposure metering,

while the white side allows white balance correct which is so important in the field of photography digital.

Technical specifications

     Gray side: reflection 17.8%; Density 0.74
     White side: reflection 92.0%; Density 0.036
     Max. Deviation from reflectance: 2%
     Max. mistake in measurements of exposure: 1/8 from F.-stop
     Dimensions some paper: 8 "x 10 " And 6 "x 8"(About 20 x 25 cm and 15 x 20 cm.)
     Core material: composite high density on paper
     Material gray side: special paper with flat spectrum coating 18%
     White Side material: special paper with flat spectrum of coating 18%

Set of two flexible check cards takes guessing out of setting perfect exposure and color balance, that can only be archived with high quality Mennon Gray Cards with the uniform spectral reflectance, regardless of wavelength, color or intensity of the illumination. Each card has two sides: one side white and other is gray. The gray side used as a reference area for exposure metering while the white side enables correct white balance that is so important in digital photography.
