I've tried 3 ways to take a picture and convert it into black and white, camera black and white filter, and chroma zero, but I think it's slightly different!
It's not an absolute method, such as machine and printing quality, but I think I can understand a little bit of clarity.
Is it correct that it becomes famous in the order of garnish - 65-66-69-64-68-67?! Two of the three methods look like this!
