CINESTILL CS-LITEBRITE+ 130% 增光片

Finally got around to testing these with some pushed Portra 800 and the difference in shadow detail was immediate. The sheets cut to size easily and fit perfectly in my film holder.

Popped one of these sheets behind my enlarger and the difference in brightness is immediately noticeable—prints now expose in about half the time. The 130% enhancement claim feels accurate, and the sheet cut easily to fit my setup.

I was skeptical at first, but these sheets really do punch up the exposure without blowing out the highlights—my last roll came out with noticeably richer shadows. The 130% enhancement claim actually holds up in practice.
