CINESTILL CS-LITEBRITE+ 130% 增光片

Finally got these under my 4x5 enlarger and the difference in brightness is immediately noticeable. My test prints came out with much better shadow detail than before.

Set the sheets under my enlarger for a test roll and the difference in shadow detail was immediate. They really do boost that 130% light gain without washing out highlights, which is exactly what I needed for pushing film. These are staying in my kit for good.

I was skeptical about how much difference a sheet could make, but the 130% light boost genuinely helped me nail exposure in a dimly lit studio. The physical handling is straightforward too—it lays flat and didn't introduce any unwanted glare or color cast into my shots.
