3in1 Photo Reference Tool Gray Card Target White Balance Exposure Temperature Color Calibration Chart Perfect for Photography & Video Test to Calibrate Canon Nikon Sony Olympus FujiFilm Camera Photo

Great tool! I do product photography and the light changes constantly due to a window that faces south. Since the room cannot be dedicated just to photography, I can't block the window. So each hour I incorporate this card into my shots and I am able to keep my white balance and exposure in line with my work flow. I use Adobe Lightroom to do minor corrections for multiple photos. This card is the key ingredient to making Lightroom able to do this for me and saves me hours in the end. The low cost and matte finish were key in me selecting this as opposed to others.

I went to J.Cristina.com to find out more and was able to come up with the directions. After that, it was fairly straightforward. I've provided below so you won't even have to google! ;)__________________________________________________Beautiful portraits, gorgeous landscapes and perfect exposures are only seconds away!The 3in1 Photo Reference Tool is super simple to use.

Exactly what I wanted. It works well.

• Card is thinner than a credit card.• It allows light to pass through from the back.• No protective case is included.• The surface has a pearl finish, not completely matte.• The focus registration reticle line weight is too thick for macro photography.

Printed on thick card stock. I keep mine in a ziplock bag taped to the back of my slate (clapper) for quick and easy setting of the white balance on my two DSLRs prior to video recording interviews. This prevents different color appearance between the cameras once the footage is edited together.

This is the perfectly sized gray card to carry around in your camera bag!It does the job and is very sturdy also.

It is the cheapest color checker out there. I mean it is just a color printed card and everybody sell it so expensive. I think this has a reasonable price. I must say that it is not made with great quality materials but it can use some case to protect it and it will last enough. Very useful tool, especially for a Sony camera owner.

I ordered this PRT card through Amazon and it was supposed to ship from jcristina. All I know is it came from San Bernadino in a plastic Amazon envelope.The product I received deserves 1 star. Take a look at the photos I included - fronts and backs of the plastic PRT card and its instruction sheet. Clearly the product I received doesn't match the description or the product photo. I'll summarize.1 - There is NO white patch anywhere on this card. NONE. You get a pale violet instead. So there is no easy way to adjust your white balance.2 - The "exposure gradient" - all the gray steps between white and black - it doesn't exist. Half of it was completely replaced by blue and pinkish patches which resemble - but are NOT the same colors as on the back of the card.3 - That big gray patch with the focus fine tuner - it's not gray - it's greenish. So you won't be using that for exposure or white balance either.4 - There's supposed to be cyan, magenta, and yellow patches to the left. There's no yellow. You get a dirty green yellow instead.5 - The back of the card is another miss. It supposed to start with pale tints that get more saturated as you go down. But the patches here are so colorful they're useless.I don't understand why the card is SO different than what is shown and described. I even saw a video of this jcristina product. I can't believe this card was produced by the same people. I don't think a photographer of any kind made this. The free coffee ring and subtle stain on the instuction card was just a bonus.
