## What is Filter Simulation?

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!

## Key features

- Simulate optical filters for B&W
