dsh-depth-of-field

Figuring out depth of field by hand means juggling aperture, focal length, subject distance, and sensor format all at once—slow and error-prone. dsh-depth-of-field collapses that workflow into a single structured call: pass in your shooting parameters and get back a precise, fully detailed DoF result without flipping through formula tables. At its core, the depth_of_field tool applies standard optical equations to solve for near and far focus limits, returning structured numeric values that are ready for downstream use. The implementation is pure Node.js with zero network dependencies, so every call resolves instantly and works completely offline. It is a good fit for photographers and videographers who regularly estimate bokeh ranges—whether dialing in front-and-back blur for landscapes, finding the macro sweet spot, or feeding precise DoF numbers into an AI-assisted pipeline as a reliable computation step.
