G7 Certified Neutral White Balance Studio Card - Reference Gray Card (3.5" x 6")

I'm very happy with this WhiBal card. It's extremely easy to use, portable enough to take anywhere my camera goes, and has made a big difference in color balancing. I used to spend lots of time tweaking in-camera and in post editing to try and match the colors I was seeing before they were shot with my camera. Now, I can honestly say, the time spent doing the above is minimal. There are so many products, from very cheap (from coffee filters to playing "I spy something white") to very expensive contraptions claiming a white balance experience so incredible you'll feel like a York Peppermint Patty from the clean, clear cooling effect. I figured I'd meet somewhere in the middle and invested in a professionally designed device with clear instructions, a professionally presented website, and a lot of positive reviews from people who have actually purchased and used this item. After using the WhiBal card, I am glad I did not over-buy a more sophisticated product that may be excellent, but would be overkill for what I needed. I'm also glad I didn't just settle for utilizing a vagrant white target I could try and balance my colors on. I plan on buying the smaller card I can keep in my wallet for those spontaneous shots my studio card isn't invited to. I haven't been in the dslr arena very long, and I don't profess to know everything about digital photography, but when I do drink beer....I prefer Dos.....Oops....I'll just close by saying this white balance card is excellent, and I couldn't be happier.

Digital cameras are marvelous devices in that the newer versions often have an automatic white balance feature built in. This is great, until you find that the fantastic photo that you took of someone comes out with a greenish skin cast or make their face look like they had a mild sunburn. Then you have to fiddle with your photo editing software to hopefully correct it, spending valuable time when you could have been doing better things. The WhiBal G7 Certified Neutral White Balance Card is the perfect field tool for this. It's a small keychain card, measuring 1" x 2.2", and is attached to a stainless steel Nite Ize S-Biner #1 that's about 1½ long. It came in a small zip-lock style bag with an explanation card, and listed the Michael Tapes Design site where support information can be found. Though they show it attached to a key ring, I chose to keep it in my camera bag so that I can clip it to a zipper pull when in the field. This simple little product gives the photographer an easy, fast and cost effective way to get accurate color results when shooting with digital cameras. Whether you shoot RAW or JPEG, the WhiBal card is an excellent tool for reproducing accurate color in any shooting situation. This G7 card is waterproof and won't absorb dirt. It can be rinsed off in the sink, and can be cleaned with a non-abrasive glass cleaner if it's gets scruffy in use. If this version is too small, there's also the larger WhiBal G7 Certified Neutral White Balance Card , a pocket card which measures 2.1" x 3.35" which is about the size of a credit card. There are other larger sizes as well. This WhiBal G7 Certified Neutral White Balance Card lives up to the product description, and the Michael Tapes Design support site has excellent info. It's a good asset to have with newer digital cameras, but it's excellent with older ones which may have white balance issues. It's an excellent way of getting white balance right with a digital camera. 4/17/2013

This product should be illegal. I thought I took decent pictures until I started reading about white balance. This item came up in my query, and I thought it was one of those "buy one get one free at $19.99 2 A.M." deals. However, I took a gamble and realized that it made my older photos look like I took them with a beer filter. How this item works is that it has a neutral gray, a spectrometrically (may not be a word but they used Science and Stuff) measured white, and black. What you do is have your model or subject hold this card with the three values facing the camera, take the pic, then take the pic normally in proper lighting and exposure. In post-pro, you open the reference image with the subject holding the card via photoshop and add a levels adjustment layer. You'll see the three eyedroppers (gray, black, and white). Use each eyedropper on its respective value on the card, and you will see your photo drastically transform in seconds. Now, move the image window outside of the frame and drag the adjustment layer on the photo you shot with the subject without holding the card, and BAM! The levels from the reference photo are transferred to the final picture, taking all guess work out of the process. BUY THIS NOW! It's cheap, portsble, and effective. I'm just starting to get serious about photography, and I feel this will turn into a a better photographer. You'll like the way your photos look, guaranteed!

All in all this product will help your photography. It fits into larger pockets easily. It is a great help in setting post production white balance and levels. When shooting candids or fast changing scenes such as children, I find it helpful to come behind and take a quick shot of the WhiBal card in the location of the now finished action. While that may not be a textbook move it gives me a much better stating point reference for post processing. I have been satisfied enough with this card that I am thinking of getting a smaller WhiBal card for my compact camera. For further details read on: The WhiBal G7 is a good tool for post production, software editing. The white and black reference help for adjusting Levels. The neutral color of the card itself is a good enough reference for adjusting midtones. I say "good enough", because midtone adjustment can be very subjective. As for RAW editing of white balance I have found that the eye dropper picks on the card in the same file image will yield different results with each pick. The variance of picks is not huge, but it is something to keep in mind when editing. I don't blame this variance on the card. However, this does make a good lesson for demonstrating the subtle differences in light and the stacking of tolerances between lens, sensor, software, and everything else before, after, and in between. While 3.5" X 6" is a decent size, I usually find it to be too small to fill the frame when attempting to set in-camera, custom white balance without casting a shadow from me or the camera lens. Obviously, this is partly due to the choice of lenses that I use, shooting distance, and light source location. That being said, when I have been in tough lighting situations such as snow, I do my best to get a custom white balance set using the WhiBal, because even though the setting is only good for that one spot at that one time, I believe that I get a closer setting to reality than the camera can get. Also, that custom setting coupled with some WhiBal card shots really speed up post processing.

This is an ABSOLUTE MUST OWN for photographers and even more so for filmmakers. The quality is excellent. I wish it was double sided but unfortunately it's not. However, it is on textured plastic so it is matte. Therefore, you will not get glare or smears on it which can become an issue when trying to white balance in post. The card itself is credit card sized. If you need a bigger one, which you shouldn't--look for the studio version. It is certified neutral. This is very important especially for film makers because when comparing this to other "18% grey" cards you can instantly tell the other ones are not. If you've ever shot video, especially log or RAW, you'd know using something as a reference for white balance that claims to be grey or neutral will leave your footage either with a slight magenta tint, or everything will look like it is fine but skin tones may look a little red adding more time in post to correct. This is what actually led me to purchase this card. A lot of great cinema cameras do not come with auto white balance (which you shouldn't use anyway) and when shooting in a good codec, log or RAW; most of your white balancing is going to come from post production. If you use Dvinci Resolve as I do (you should be for color correcting if you don't), using the qualifier to select this card as your neutral key will result in excellent balancing every time. Do yourself a favor and skip the ones that are $10 less and get something that's certified. Or else you'll be spending extra time trying to figure out whether your balance or tint is messing up those fine details with an awful hue.

Hard to fill the frame in the same lighting conditions as the subject as it is quite small. The next larger size (about the same as a credit card) works fine and is kept in my wallet. The latter works quite well, and better than a white card or camera’s AWB.

I've been using Michael Tapes' WhiBal cards for a dozen years. They have allowed me to consistently achieve accurate white balance in my images. While digital camera auto white balance has improved markedly in the last dozen years, there are still too many situations where it fails and leaves a color cast in your images. To achieve accurate color representation in your digital images, you must shoot RAW and you must have test images with a known neutral target in them, in the same light as your subject. Only then can you accurately adjust white balance in post processing to remove unwanted color casts. The pocket size WhiBal is ideal for use in the field. It's small enough that you actually carry it with you all the time (I keep mine on a lanyard around my neck when I'm in the field shooting). If it's convenient to carry, it gets used. There are larger cards; I have them and use them in the studio. But the pocket version is what travels with me 100% of the time when I'm out in the field.

I already have the credit card-sized WhiBal card that I always carry around in my wallet, but sometimes that's a bit too small a target. That's when this thing comes in. At 7.5"x10", you've got a sizable target even from far away with a wide angle lens. The color accuracy of all WhiBal cards is fantastic and as far as I'm concerned, they're the GOLD STANDARD for white balance targets. If you read some comments about WhiBal cards in general, you'll discover that they have changed over time. While this latest generation certainly isn't as "robust" as some older iterations, it's more than durable enough for any sensible use. I would highly encourage photographers to pick up one of these cards as well as one of the credit card sized ones that they can keep int heir wallet. It's just a quality product that will do wonders for your white balance.

A pesar de su tamaño la tarjeta cumple con el objetivo perfectamente, permitiendo ajustar la cámara para que capte los colores correctos en distintos escenarios y tipos de luz, es de gran utilidad, lo recomiendo ampliamente. Cuesta un poco hacer el enfoque por el tamaño de la tarjeta, sin embargo, nada extraordinario.

Compact, solid and handy

Sturdy and compact, should last a long while. Pretty pricey for a card though!

Great simple product, fits in my wallet for easy access. Does a great job assigning the right colour temperature in awkward lighting.
