PHFX | Tools

Developer's Description

This is a collection of interactive web tools designed for motion picture and stills professionals. These can be used to plan your shoots with camera or format comparisons, framing guide generation, data footprint calculations, camera operating notes, and exposure assistance. The tools can be shared, bookmarked, and saved to help communicate these concepts to crew members who may benefit from the information and working within industry standards.

These tools are a result of my particular filmmaking career experience and research in motion picture productions, working with studios, post houses, production companies, and manufacturers around the world. I started sharing the earliest iterations of these tools in the early 2000s with bespoke designed data sheets. Those were shared globally, which inspired the move to make the information and tools interactive. What you see now is the evolution of the tools / apps along the way.

These tools are provided by myself, made publicly available, free to use, with no ads. Thank you for the tremendous support over the years.
