Review on 📷 Kiorafoto 3x3 Easy Carry Professional Camera White Balance Card: Grey Card Film Filter & Color Checker for Temperature Calibration by John Bailey

I have the original ExpoImage, JJC WB-F1 and now Kiorafoto. I'll be blunt: THEY ALL DO THE SAME JOB. JJC makes it cheaper than Expo and Kiorafoto makes it cheaper than everyone else! I loved my JJC because of the size and the nice grip. The lens diameter is slightly larger than the Kiorafoto, and because the lens is round rather than enclosed in a protruding side frame like the Kiorafoto, it's super fast and easy to hit with any lens, especially a 70-inch lens. 200mm and lock the white-on-white exposure. I really liked the JJC (I still do) but I had a bad habit of putting it in my back pocket. I knew that one day I would sit on it. Aha! I watched the event from the front row of the auditorium, backed away and banged my back on the armrest of the row of seats, hearing and feeling an uncomfortable crunch. Needless to say, I flinched and said a few angry words to myself. I pulled it out and one side of the lens assembly was pretty badly damaged. They all consist of two identical plastic lens surfaces that restrict light with a refraction of 18%. Anyway, I grabbed some duct tape and put the little broken puzzle back together, save for a decent sized piece. I'll tell you what...even if there isn't a fragment...it still nails the BB perfectly, and the tape won't affect it. Boy Scout Honor. I know because I tested it on Expodisk in many situations. These tools are not as important as they would have us believe, which is why fakes are getting cheaper and cheaper. It's like comparing Walmart's version of Tylenol to real Tylenol. We all know it's the same product! A little rabbit trail for those who don't understand what happens when you adjust the white balance: you can verify that the in-camera white balance is correct if you know how to access and change the in-camera settings. Histogram for display in RGB mode. Read the camera manual if not. Instead of a single white bar graph in RGB mode, you'll see three (or four) graphs: one in red, one in green, one in blue, and then possibly a fourth in just white or grayscale. After adjusting the white balance using any method (gray card, expodisk, etc.), take your first shot. Look at the RGB histogram...look at all three color charts...their shapes and positions should be nearly identical. If the blue color is shifted slightly to the right, look at your image on the monitor screen... it will prefer a colder tone. If the red is shifted to the right or, for example, the blue is shifted to the left, check your photo... you should find a warmer picture, or maybe red is saturated. It is so easy. This is how you can determine if your white balance is "balanced". You simply "balance" the red, green, and blue aspects of your photo so that white is white, black is black, gray is gray, red is red, blue is blue, etc. Your whites and blacks are most important. If they are good, then everything else is fine. When it comes to color reproduction, some cameras may display colors differently than others. That's it. A quick comment: don't worry about exact perfection of the R to G to B plot curves. Actual curves may vary slightly. Compared to the film days when we only had a few color filters for tungsten films or daylight films. Trust me... your in-camera white balance calibration is now more accurate than film ever was. However, if the curves of, say, blue are flattened or have a much higher peak than red and green, then you've done something wrong. Try again. OR...that's what you get for custom white balance. Or maybe it's really okay. Just look at the picture. So back to the Kiorafoto review. That's great. I love the concept of the strap (but I could do the same with my JJC I think) and I love the smaller size. Again, it's square and the outer edges protrude on one side. When aligning with the lens, you have to move a little more slowly. And it barely fits 70-200mm. So I'm just a little on the hose. It looks like the extensions on the edges are for attaching color correction filters, which you'll have to buy separately and cut and paste to fit. The instructions for this tool are painfully vague. Even the instructions with JJC are much more intuitive to understand how to use the device properly. The concept of adding color correction filters is not far-fetched. Expodisk now offers versions with slightly warmer white balance for skin tones. You can do it yourself by experimenting with CCO filters, and Kiorafoto provides the tools to do just that. Absolutely brilliant! But again, the very short and concise guide doesn't mention this. All in all it's an impressive package with a cute little cover, but the lack of a detailed instruction manual can be blamed I guess...it's only $8! One last thing: I like this method WAY more than shooting white or gray cards or shooting an X-rite card. It just works a lot easier and makes it completely painless. This makes the same thing a lot easier, IMHO. I hope that was helpful.
