Great deal!!! This is a mid-gray board that I used when shooting with a film camera. It's very useful when shooting with a built-in light meter. When measuring with a simple reflected light meter built into the camera, bright subjects tend to be underexposed and dark subjects tend to be overexposed, which can lead to exposure failures. In such cases, by first holding this board in front of the subject and measuring the exposure, you can get a value close to incident light metering, eliminating exposure failures. There are two sizes: large and small. Feel free to take either one! Here are the prices: Large size (20 x 25.5 cm) 700 yen each Small size (10 x 12.5 cm) 300 yen each I don't think there are any stains, but there are some scuffs on the corners from being stored at home, so please understand. For those who understand long-term home storage. We will ship safely and securely. Please understand that we will use simple packaging. #Tamago's Camera
