White Balance Grey Cards 18% Gray Cards Custom Color Calibration DSLR/SLR/Evil Camera Checker for Digital Photography Video (3.35" X 2.2")

Item is compact and fit easily into your camera bag. Necessary item to ensure proper exposure. Good value and functionality and easy to incorporate into you workflow.

Using for infrared photography and works well for camera white balance. Nice size for outdoor usage. Durable plastic. I wish it would come in a protected sleeve to keep cards clean but I did find a sleeve in the house I can use.

This is an amazing product, very handy for sports shoots when I’m in a new arena. My only gripe is that I wish it were a tad bigger as it is hard to lock focus to set my settings, but for the price it is great.

Perfect thanks

Does what it says on the listing...even includes the lanyard if you wanted to use it. And I like the cards are thick enough (credit-card thickness) they don't shine light thru to mess up the color. Good for the price.

I don't always need a grey card, but sometimes I REALLY need a grey card, and I keep forgetting my larger card. This fits in my camera bag very nicely. It's nice and durable as well so I don't have to worry about something tearing or folding up.

Exelente material se sienten resistentes no se rayan ni puerden color el coyar es de buena calidad

So part of the issues is really I did not read the size. That said the rating is more due to what I once had being a rigid plastic set of white balance cards no longer available sadly. So my new camera apparently can select a section of the card and set the white balance. I primarily run the black or grey card for contrast. Images from the air museum in a dark area with spot lots produced super good images. The hydro plane races also came out really well. If your camera can select a small spot on the card you are golden. I was running a lens initially for the boat races near 1000mm which cards were really a blur. My ribbed post card plastic white balance cards in direct light are superior but lost them. Drawback they had was size which your typical cards solve. The one star ding I would put here is lacking the ribbed feature to disperse light across the cards evenly and not being a hard plastic. Otherwise not sure they are superior to like cards you see all over Amazon. So if the price is right these will work.
