JJC 4" x 5.2" PVC White Balance Card Set for Achieving Perfect Color Balance in Your Photos - Including an 18% Neutral Grey Card, a White Card and a Black Card

I tested these with no flash under a 75 watt incandescent, and with a YN560 at 1/16 bounced off the ceiling. I checked the color temperature in Photoshop's RAF import tool, and it showed 2900K for the incandescent, and 5600K for the flash. Inspecting the RGB, black and grey were neutral with respect to each other, but the white card was slightly magenta, like 161,156,160. I imported without adjustment and went into Levels in Photoshop and set the white point, black, and then grey to produce the adjusted images shown here. The black card is a little shiny though, so I used other, blacker areas in the images to set the black point.The grey card is extremely matte on both sides, it even feels matte. In fact you should be careful not to get grease on it, to preserve its matte quality. The white and black cards have a matte side and a less matte side. Not exactly shiny, but shiny enough you don't want to use the wrong side.The cards are big enough to set custom white balance in camera. My camera is a Fuji X-E2, and has a smaller rectangle inside the picture frame to set custom white balance, and the size of these cards works well with that.The lanyard is adequate, and the little popoff connector makes the cards handy to use as a set.

If you want pocket size cards, this is not for you. I need a clean color pick from a distance. These are gret. They come in an excellent protective cloth pouch. Worth every penny

I'm using a Lumix GH5 camera, and have been struggling on occasion with color casts in my photos, even when using the correct whit balance preset. These cards are the perfect size for me, makes it very easy to hold and set with the camera in one hand and the card in the other. Really changed how I'm approaching photography, especially outdoors.

get on your way to get photographs that reflect the situation and not a certain mood.Very easy to use and to get results.Google on how easy it is to use them.Just one photo on location with those cards and you know you get results in post processing that are impossible without them.

They're black, white and gray color cards. I'm not sure what there really is to rate about them. They indeed appear to be black, white, and medium gray. They're plastic or vinyl or something and appear pretty sturdy. There's not much more one can say about them.

Perfect size and easily transportable. Love that it comes with a lanyard as well.

Card size is very good. Big enough to get reading and small enough to travel.

Exactly what you expect. Make sure you read the size. Comes with a lanyard for easy use.
