Adorama QpCard 101, 3 Cards with Black / Gray / White Colors used for the White Balance System of Digital Cameras.

I'm a product photographer for a leading brand and I use these at work pretty much everyday. GREAT INVESTMENT! Good for indoor, outdoor or studio lighting. Also worked great for video editing purposes. Keep one at home and one in my personal camera bag. Won't ever be without one of these again.

Just don't buy it. Three coloured small papers for $12 is just rediculus. Its too small when framed with your subject while shooting. It's paper and not durable at all. Cannot be used for monitor calibration as some ppl may think, you would need a proper calibration equipment if you wish to do so, because the idea of the caliboration is not to depend on your eye evaluation for colour matching. For $25 you could get a much better folding plastic cards.

I was disappointed with these - you can't tell how light and thin they are from the photos. They are made out of light paper. I would have gotten something more durable and not wasted money on these if I had known. When they are in the camera bag they get crumpled and damaged easily, and if they get wet (I should have known!) they turn into a soggy mess. For a paper card printed with black, grey and white paint, these are too expensive.

I use these cards to take a raw digital image that I can then use to get an initial color and exposure adjustment on my following images. It is small enough for my small camera bag.I would prefer a more rugged coating, but the price is right!

The QP101 card enables me to convert RAW images to perfectly colour and contrast balanced images using Adobe Photoshop. Excellent.

I thought that I was getting 2 tablets of cards-- not 2 cards! There is nothing wrong with the product but the price is highway robbery!

The grey card was made of a thin, piece of paper. What happens when you have a small piece of paper in your pocket,or in your bag? The paper is easily bended, scratched, scrambled... that's what will happen to the card shortly after you take it out.

You might be confused (as I was) by the description referring to "a pad of 15 QPcards" but it's actually only 3 cards. That said, the cards are a good size for carrying in the camera bag, and come in a resealable envelope.
