Gray Card Background

In the process of developing a standard for research grade images, which are mostly covered in this video , Roy Larimer stated that the standard for digital imaging is 11-12% neutral gray.  He made a batch of powder-coated aluminum plates f.  Below is a suite of images of a plate he sent me (12in X 12 in) and a couple of shots taken with a Samsung 7 using LED lights.  I do not have a high res image with studio lights, but these plates are absolutely wonderful.  They provide a very nice smooth background and if they are cared for properly, they will last forever, you can use both sides of the plate.

I am selling the plates at cost for $60 as long as Roy makes them.   I currently have two plates, one I will not cut and the other I plan to cut into four 6 X 6 in plates.  I drill a small hole in the middle to put the pinned specimen.  You can just putty was/putty or whatever you want on top of the plate instead of the hole.

You do not have to go with 11% gray background, as long as white balance is addressed.  If you are fine with 18% gray card you can download this pdf file and make your own gray card.  The quality of paper and printer will determine the quality of the background. Gray-Card-18-percent-RGB-128

You can also purchase gray cards from Amazon and several photographic sites.
