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

This a clever little product that meets my need perfectly. I used mine to perform custom white balancing in the field on my Nikon D600. It came in a small zip bag and pops open when you take it out. I mean Pop! It weighs like a feather and it's cloth over wire frame construction means it's very easy to set up against a tree or whatever in the field, set white balance, then pack it away. So it's both compact and under 4 oz., great for your gear bag in the field. The wire frame makes it less likely than a piece of gray card to blow away. The cloth means it's possibly cleanable as well. Just what I wanted for the field! Light, cheap, reliable, practical. My D600 read the grey face but not the white face.Here's how to fold it back up so it'll fit back into the pouch: Note that it is roughly rectangular with 4 corners. With both hands pinch two catty corners or opposite corners on the diagonal, doesn't matter which two as long as they're catty corner. Bring the 2 corners together so it's pinched together in the middle. You now have 2 corners together and it looks like a sort of butterfly shape. Holding the pinched corners with one hand, turn that hand inward towards you so the back of that hand faces away and the 2 "butterfly wings" face at you. Using your other hand bring the bottom wing up and into the middle so you can now pinch that lobe as well with the hand that has the middles pinched. Now holding all that with one hand, bring the other lobe over and down on top and, keeping it pinched bring it all together in the smallest size and slip it back into the pouch whilst keeping it all pinched together. A lot to write down for you, but do this once and it's a cinch forever!

works fine, is foldable

Very cheap and easy to carry in your camera bag. Its a must to help get your white balance set before you start shooting your pictures. Most modern mirrorless cameras can use this handy device to set the white balance and help improve your pictures dynamic range and colors. This will reduce the time you have to spend when editing your pictures on your computer.

It's not perfect but it's not bad either. At such an inexpensive price point, it's hard to beat this. I accidentally bought two but kept both because the price and small size are perfect. I have one in my camera bag and one in a loose ends/backup bag for when I'm traveling on-set.On my GH5, this works just fine for setting white balance. I've tried with both the white side and the gray side and both seem to produce the same results.Plus, it's pretty fun to snap it open when pulling it out of its 4" x 4" bag. The quick and easy fold-up means it's perfectly compact and will fit in a camera bag, back pocket, or whatever other small space you have available (the side pockets on a camera bag work great).Clients also love it. It's something they can quickly hold and it seems like giving them something to hold while getting the frame set helps reduce their anxiety about filming.Get one. Given its low price, you can't go wrong. It might not be 100% perfect but it's almost perfect and especially so for the price it's at.

Can't go to a photoshoot without it now. Apart from getting the correct WB, I found out you can get the right exposure as well without purchasing a lightmeter. This will suffice for now, I love it.

Simple and sweet. Grey side for exposure, white side for white balance, folds into your pocket. I love it, clients love it, it helps in post production and on set. 10/10

As a photographer, I prefer to set custom white balance settings as often as I can and this little gray card has been great for that. I love that is large enough to quickly and easily capture on camera, even when working solo but fold up so small for storage. I started out with one to try it out and found myself always going to find it and move it around between bags when I decided that it would be easier and thanks to the price, very cost effective to just order a few more to keep one permanently in every bag to just make sure I always have one with me. My original one that is a few years old now, has held up perfectly and is in as good a shape today as the day I got it. Worth every penny!
