 Gray Card [8in x 10in]   Price: $6.25
 

A gray card allows you to get the perfect exposure & white balance. It's the perfect low-tech solution to a complex problem! 

Perfect Exposure!
The exposure meter in your camera measures the amount of light that is reflected back to it from your subject. The meter is calibrated to EXPECT that your subject is always has a reflectiveness of "medium gray", but it often does not! So, what your camera does is  try to make
everything look as if it has a reflective value of medium gray.

Don't believe it??  Try this: Photograph a piece of white paper, with nothing else in the viewfinder. (You'll probably have to use manual focus, as the AF system won't be able to focus on the white paper.) What you'll get is a solid gray image - NOT WHITE. Likewise, photograph a piece of black paper or cardboard. Same result - both will come out looking medium gray.

Now that we're past that, here's why you need a gray card and how you use it. 

  1. Put your camera in P (program), A/Av (aperture priority), or S/Tv (Shutter priority) mode and set your Aperture when in A/Av mode or Shutter when in S/Tv mode..
  2. Put the gray card in the same light as your subject, fill your frame with the gray card and press your shutter half-way. Read the f-stop and aperture shown in your viewfinder. This f-stop and aperture is what you should use to expose your subject.
  3. Now, put your camera in MANUAL exposure mode and set your aperture and shutter to the settings your read when using the gray card. This will yield the correct exposure for your subject.
It's incredibly easy to use and it produces predictable, repeatable results.


Perfect White Balance!
You can also use the gray card to determine accurate white balance using the "custom white balance" feature built into most digital cameras. Because the gray card contains no color other than gray, it's the perfect target for determining the white balance of any light source. It's a MUCH less expensive way to get the correct white balance than most products designed to do this, and it's just as accurate!



We know of no other product that can be of more use to a digital photographer.


Here's the difference between letting the camera decide the exposure and using a gray card.
These pictures were taken with our Shooting Tent with a black background with one incandescent light bulb for light. You can see how the dark background color "fooled" the camera into thinking there was less light than there was, so the camera over-exposed the image. The camera tried to make the background gray, as that's what it's programmed to do. The Gray Card told us what the CORRECT exposure was!

As you can see in this first image, all of the detail in the necklace has been lost and the background is way too bright.
Gray Card Difference
In this second image, we used the gray card to determine the correct exposure - as you can see, the necklace retains all of it's detail and the background is it's proper black color.

One side of this card is the 18% gray card, and the other are instructions for using the gray card for exposure, white balance and determining lighting ratios (when main and fill lights are used). We also include our own instructions for using the Gray Card.
