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

This smart little product fits my needs perfectly. I used mine to do a custom white balance in the field on my Nikon D600. It was packaged in a small zip bag that opens when you take it out. I mean dad! It weighs like a feather, and the fabric-over-wire-frame construction means it's super easy to set it up against a tree or anything in the field, set the white balance, and then put it away. So it's both compact and weighs less than 4 ounces, making it a great fit for your gear bag in the field. The wire frame makes it less likely than a gray map piece. Cloth means it may also be able to be cleaned. Exactly what I wanted for the field! Light, cheap, reliable, practical. My D600 read a gray face but no white face. To fold it back up to fit back in your pocket: Note that it's roughly rectangular with 4 corners. With both hands, hold two cat corners or diagonally opposite corners, any two, as long as they are cat corners. Bring the 2 corners together so they pinch in the middle. Now you have 2 corners together and it looks like a butterfly shape. Holding the balled corners with one hand, rotate that arm inward towards you so that the back of that arm is facing to the side and the two "butterfly wings" are facing you. With the other hand, lift the bottom wing up and into the middle so you can now pinch that punch with the same hand holding the middle. Now, while holding everything with one hand, move the other lobe up and down from the top and keeping it squeezed, gather everything in the smallest size and put it back in the bag, keeping everything squeezed. Much needs to be written down for you, but do it once and it's forever!
