Optek Premium Reference White Balance Card Set- 3 Card Set- 3 Card Digital Color Correction Tool

These 3 cards are precisely the size of a credit card, so they will fit in your wallet or a cc holder. The surface of each card is matte black, white, or gray...which reduces color casts from reflections. Each card colors is solid through the plastic; the finish won't scratch off. To my eyes, the three shades appear perfectly neutral, but since plastic often yellows with age, I'll keep these away from sunlight and open air. For the price, they look very durable; the lanyard them secure on outdoor shoots. If there's any downside to these cards, it's that the size is a bit too small for getting a positive reading off wider angle lenses. So far in use, these cards have helped me accurately set white balance; I'm a very satisfied buyer. Made in USA.

I ordered this item to help me improve my photo taking, more specifically, my to help with my post-processing workflow. The cards are plastic and not laminated paper stock like some and they are waterproof and easily cleaned with water or household cleaner. They are compact and fit easily in either a pocket or your camera bag. The included lanyard is a nice convenience feature also.I've always had trouble finding the correct white balance in post processing and this tool has helped immensely. I'm sure I have not used it to its potential yet, but I got it just before Christmas and used it on Christmas Eve during setup at my parents' house for Photos of the grandkids. It did a fantastic job of helping me correct the color balance of the pictures during post processing.It's very simple to use: just take a photo of one (or all - one each) of the cards under the lighting conditions that you will be shooting under. When you go to post process you correct the color balance in your photo editing program for the test photos and copy the settings to the entire shoot. I personally use Lightroom and it was a very simple process to complete that took under 5 minutes total to correct all of the pictures I took that night.I would highly recommend this product for any photographer who is starting to take their craft more seriously. For under $10 you can't go wrong with this product.

It's a nice set of gray card with lanyard and three set of cards. The gray card is supposedly at 18% gray to provide neutral gray for luminescence. The white card and black card provides the two ends of the exposure scale so you can use them to set the two ends of scale when adjusting exposure of photos later on. However I found that the neutral gray doesn't always generate a correct white balance. Most of the time it is a little bit too warm or too cold on the color. But with some adjustments usually I can get it pretty close to a pleasant white balance. There's the limitation but overall it's an okay product for this price.******** Edited on Apr 28, 2016I have eventually decided to return the product. I found that on multiple occasions when the lighting gets complex, the gray could not generate the correct white balance and I have issue with determining the correct white balance after all.

I come from the old school when 18% gray cards and MacBeth color checkers were de riguer. Gray cards were cardboard, unwieldy, and subject to damage. This is a handy idea, though I haven't had the chance to put it through paces yet. It's compact enough to throw in a camera bag, and durably made of a tough plastic. An exposure with these cards in the corner of a frame is plenty for Photoshop or another high quality photo program to take readings from for color balance and brightness. This isn't the type of card that one would use to take reflective meter readings from, though I think that most photographers who have the need to meter separately from the camera's usually built-in meter will probably be using incident metering anyway. In all, this seems like a useful and durable product.

What more is there to say about a couple of colored cards? They work well, hold up well, have a great finish, and seem like they'll last. The color correction they provide is excellent. They're small, but plenty large enough to do their job. My only challenge is remembering to get a shot of them every time my lighting changes (I do a lot of even photography)

Bought this set to use with food photography. Having accurate colors is incredibly important when doing food photography.This set works like a charm. Fairly accurate, the cards are a thick plastic that seems quite durable, you can wipe dirt and such off the cards with a wet rag to clean them, the lanyard clips off at the bottom making it easy to hand these to a client quickly!, they hang around your neck which helps keep them constantly at hand! I usually get quite flustered on shoots and tend to stuff everything in my bag but with this lanyard I finally KNOW where I put it! lolGreat buy and well worth the $8 that I paid! I have recommended this item to friends and strongly think that it is a must for people who shot a lot! (WORKS GREAT WITH MULTIPLE SPEEDLITE AND STUDIO LIGHT SETUPS EVEN OUTDOORS!)
