Best Photographic Light Meter Grey Cards in 2020



Lightdow 12 x 12 Inch (30 x 30 cm) White Balance 18% Gray Reference Reflector Grey Card with Carry Bag [Folded Version] Review:


First, functionality. It’s a gray card, so I expect it to give me 18% neutral gray upon reflectance. And it did ever so easily. I included a couple of test pictures with Bambi. The first picture is indoor, with LED ceiling light on the soft toy. The second picture is when the white balance of the picture is corrected with the gray card. Not bad, isn’t it? I shoot all my pictures in RAW format, and if you happen to use a Mac like I do, you can just load the photos into the Photos app on Mac, go to Edit, then Adjust, and the White Balance menu. Make sure that you select Temperature/Tint in the dropdown box, then click on the little dropper-like icon right beside the dropdown box, and then click on the gray card. It corrects the white balance using the gray card as a reference for neutral gray. Then you can simply copy and paste adjustments and correct the other pictures taken under the same lighting. Simple enough.

The Lightdow graycard arrived in a round black polyester bag (about 4 inch in diameter), with a small hoop at the top of the bag for easy attachment to camera bag or backpack by a clip or a caribena. Though the graycard bag material does not convey any feeling of luxury (not that I care anyway), the zipper works very smoothly without any glitch I would typically expect of a poorly constructed bag.

The gray card in itself measures about 12 inch by 12 inch when fully extended from its collapsed state in the bag. It is essentially a very soft, velvet like fabric wrapped around some rather flexible plastic scaffold (along the edges of the gray card). So to collapse it back into the bag, you just hold on to the opposite edges of the gray card, twist in opposite directions. Fairly easy, no surprises.

Overall, I feel this is a better choice than the credit card sized gray cards, simply because it allows me to take a picture of the gray card without having to stick my lens right onto the smaller gray cards.



Anwenk Grey Card White Balance Card 18% Exposure Photography Card 5X4 Custom Calibration Camera Checker Video, DSLR and Film  Review:


I was worried these cards would be flimsy or maybe just a bit too big. But honestly, they're perfect. They're reasonably durable plastic, very lightly matte textured. They fit in your back pocket, or just about any pocket. Big enough so that if you hold it at arms length you can get your white balance shot. Some of the credit card sized ones are just too small. These are perfect.

White Balance -- very important if you want to have your colors reproduced correctly when you take digital photographs. It is truly amazing how many times the digital camera gets white balance totally wrong and your colors look weird when you review the pictures at a later date. My example is snow on a cloudy day -- digital cameras see blue, not white.

I shoot photos in RAW format and do all my final JPEG processing (post processing) on a computer. The very first thing I do is set white balance. The second thing I do is exposure correction. Here is where these cards come into play.

* White card -- to set white balance for the scene you are shooting.
* Place the white card into the scene and take a picture, than take the card out and reshoot the keeper picture
* In post processing, use the eyedropper tool to click on the white card and see the difference
* Make note of the color temperature and use that number for subsequent photos taken in the same light

* Gray card -- what is known as an 18% gray card -- half way between black and white
* This color is what the camera strives for in exposure setting -- making everything fit 18% gray
* You use this card in a scene to set your exposure properly -- converting your camera meter to an incident light meter
* No need to photo the gray card, but you have to set your exposure using this card prior to taking the picture - exposure lock feature

I have never used the black card.

The color accuracy of these cards is good. They are small enough to keep in your shirt pocket and use in the field. They are made of plastic and clean easy.

If you are having problems with reproducing accurate colors from your digital camera, these cards will help tremendously once you get the hang of their use. It makes color correction and exposure values as close to spot on as you can get.



Movo Photo Color, White Balance Card Set for Digital Photography (Index Card Sized, 5 X 4) Review:


Perfect size and the lanyard is icing on the cake! The cards are white plastic PVC looking stuff with the proper color coating bonded to both sides. The color film isn't paper but some type of coating. Water won't hurt these cards.
I like the size because you can just get a shot of the card and use it in Custom White Balance on your camera and don't have to spend time with fiddly software to change anything. Plus, if the white balance isn't to your liking you may be able to adjust the numbers right then and there if you have a tablet or laptop or something to check your results.
If you don't use white or black you can only carry the grey card when removed from the sturdy loop. All three may be carried in a cargo pocket of your clothes or hung around your neck or over your shoulder etc. Exactly what I had in mind when I started shopping and the price can't be beat.

Sedremm Gray/White Balance Card,12x12 Inch (30x30cm) Portable Focus Board Two Sides Double Face 18% Grey/White Balance Reference Card with Carry Pouch for Canon Nikon Sony Review:


Good little pop'n go white balance target. Folds up nice and small. Scared the hell out of me when I opened it for the first time though. I have reflectors and green screen pop screens - bigger than this- its quite tightly folded and fun to watch you kid freak when they open it for you. The gray is very good and large enough for me to snap without having to zoom in to a small gray credit card which I also own. So this ends my search for a portable gray/white pop open gray card target. Good quality, and easy to pack at a great price.



Neewer Large Size 2 Card Set 8" x 10" -White Balance / Exposure Card 18% Gray Card Set for Digital and Film Photography Review:


These work well. Great for getting exposure right when you don't have an incident meter. Only thing that annoyed me was the ziploc bag they came i was so tight, I practically damaged them trying to get them out. Very tedious. These are relatively thick and do not flex which is really best for having consistent reflectivity.
