Simulate real optical filters in black & white. This app uses custom CIColorKernel shaders to modulate grayscale luminance based on color vector similarity—accurately mimicking red, yellow, green, blue, and orange filters as used in film photography. Then, if needed, save the filtered image with filter information. Then, swipe left and find an automatic shutter speed calculator for applying various ND filters And that's not all; keep on swiping and you can simulate pinhole photographs before shooting!

Silverlog Scan

Features
Read full description

Silverlog Scan calculates the scanning resolution (DPI) needed to achieve your desired print size and quality from your film format. HOW IT WORKS Select your film format (35mm, 120, 4x5, etc.), choose a print size and output quality, and see the minimum scanning DPI required. The calculator accounts for the enlargement factor from negative to print. FEATURES • All common film formats (35mm, 6x4.5, 6x6, 6x7, 6x9, 4x5, 8x10) • 13 standard print sizes from 4×6" to 40×60" (inches) • Output quality from 150 to 400 DPI • Required DPI calculation • Output resolution in megapixels and pixel dimensions • Estimated 8-bit and 16-bit file sizes • Quality indicators • Works offline — no internet connection needed • Clean, focused interface • Dark mode support USEFUL FOR • Setting up flatbed scanner resolution • DSLR scanning resolution planning • Understanding how much detail your film format captures • Choosing the right scanner for your print size needs • Optimising scan time vs quality tradeoffs Part of the Silverlog photography toolkit.
