I certainly used a “cellulose” filter on this Sun-slit Twilight. Yup that tree is all cellulose and it filtered the light that made it through to my photon capture box. Hundreds of miles of atmosphere for light to travel through to make it into this twilight image before the sunrises above the horizon and illuminate the cloud deck. This is a night sky technically. The sun has not risen here and won’t for about 9 minutes in this timeline. It’s still 3 sun diameters below the horizon or so. Dead calm, 2 second exposure, f22, ISO 200.
This image is all about the use of negative space. 36×24.
