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.

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.

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.

Does what it should do. Pretty simple and great tool for the beginners.

gray good

These are nice rigid quality materials, the lanyard is a nice touch. I bought them to use with my cell phone for product photos for our porcelain jewelry store in Handmade Amazon. I thought they would work to help me get a true-to-life color, unfortunately, the phone camera doesn't work properly with them. The quality is great, they just are not right for my use.

Have used twice in difficult lighting set-ups. It gets you pretty close. With mixed lighting (tungsten, led, fluorescent with a tad of daylight ) it’s hard to know where to start. I lose gray cards. It’s what I do. This works fine for everything except product shots.
