Works great - simple yet effective. [Posted on 2007-10-05]
I got this because I wanted a good quality gray card that wasn't made of paper and would last a while. I don't really need the white or black cards, or the deluxe lanyard (it really is nice quality though), and i basically just threw the card in my bag and left the rest at home. Kind of pricey for a piece of plastic, but if you are in the field shooting in JPG mode and need to do a custom white balance, it's worth it to me, even if it fixes just one shot. The card works great. I've used it several times already and it is a simple but effective way to adjust white balance in strange lighting situations.
Gray card is on target every time. [Posted on 2007-10-06]
Before I used this product I used white paper as recommended by Canon for my 30D. I put lines on the paper for focus and set white balance as custom. The paper was difficult to use and keep with me. Since buying the gray digital card, I have found it to be more accurate than white paper and easier to use. The digital gray card produces perfect custom white balance and works every time. It has a focus spot to get the correct image for setting up in-camera custom white balance. One time I used both the gray card and the white card (on the lanyard) and found the gray card produced the correct white balance over the white card. Now I never take a shot without setting the custom white balance to the gray card. I do this in-camera so I don't have to make adjustments in post processing. The gray card also gives the correct light reflection for digital camera exposure. Most books say the gray card should reflect at 18%, but that is not correct for digital. See article on the internet by Thom Hogan [....] who says digital camera makers set exposure meters to near 12% gray reflectance, 18% is based on printing standards. This gray card is closer to 12% and is very accurate.
I like the lanyard. When I'm outdoors I keep it on my neck so I can periodically reset the custom white balance as I shoot. Inside under lights, I use it one time and I'm set for the shoot. I highly recommend this card for serious photography, and it is inexpensive as photo equipment goes.
Excellent white balancing tool [Posted on 2007-11-22]
I bought this set with risk (expensive & don't know if it work ok or not). Turn out I am SO HAPPY with this purchase.
I did the card test:
Took a picture of this set - Put this unbalanced picture to Photoshop to white balance it - Measure the balanced picture with Photshop sampler tool and find all RGB are equal; R=G=B. That's mean it neutral 100%.
I did the camera picture test:
Took serveral pictures with different light sets - white balance the pictures with this GreyKard tool. Result color in pix look very much match the real physical subject.
So 5 stars for this GreyKard.
Some notes, may be you like to read:
This little GreyKard may not too great for doing Pre-Blancing for camera internally because it is so small in size. This GreyKard set is great for Post-Blancing using camera software or Photoshop. This is what I like for convenient GreyKard for Post Processing, reason: Post Processing allow me 2 choices (2 sets of image) to pick, First is the original pix; Second is the my white balance touched pix. Sometime the my white balance touched pictures turn the color look so real that make the people in my pictures look like "Living dead in front of a warm burning fire place" so I throw out the white balanced pictures and keep the original AWB pix.
That is so good this GreyKard set. If some subjects originally look ugly, it will make it true ugly as original.
An Inferior Copy of a Great Product [Posted on 2008-06-13]
I think this is my first review in the years I've been on Amazon, but for once I feel that I need to speak out on a bad product.
I bought both the DGK and the WhiBal White Balance Reference Card - Pocket Kit (2"x3.5") and I have to say that the WhiBal just feels better and feels that it will last a lot longer(the DGK cards are only about the third of the thickness of a WhiBal). However the Digital Grey Kard has one thing going for it, it has a superior laynard.
I would recommend spending a few bucks more and get the WhiBal White Balance Reference Card - Pocket Kit (2"x3.5") instead.
Only misgiving is price [Posted on 2008-08-31]
The three credit card size pieces of plastic work as advertised - they allow instant color correction in PhotoShop. They must be angled correctly or the glare from the flash appears white on both the gray and black cards.
They are not large enough for me to use to set custom White Balance in my camera, but they are small enough to easily fit in my shirt pocket without any problems.
This product will probably become standard in my portrait photography workflow, but I was a little disappointed when I opened the package - three credit card size pieces of plastic. My guess, and I may well be wrong, is that the packaging costs more than the product.
