Regarding the custom white balance usage of Pringles lid, it seems that everyone has a bit of misunderstanding!

What the original poster said is probably right. I used Pringles cover before using S602. I did cover the whole lens before using it. The cover is not 18 shades of gray, but transparent. The light is close to eighteen shades of gray.

When you cover the lens with a cover and point it at the scene you want to shoot, the light reflected from the scene is filtered by the Pringles cover, leaving only about 18 shades of gray light entering the lens. Then the manual white level can be set correctly. Come on! Another note: This potato chip lid seems to be the most used by FZ10 users, because the diameter of the lid is exactly the same as the diameter of the original adapter barrel of FZ10. It will not fall off after being put on directly, which is convenient~~~ Is the diameter of the lid 72 or 75mm...
