It's all about the light.

New Field of View Tool

Field of View Tool

We've added a new free tool to our website - think of it as a slightly delayed holiday gift!

The new Field of View tool allows you to visualize the effective field of view of different camera and lens combinations. It's a little like The Photographer's Transit, but for the web.

There are many field of view tools out there already, so why add another?

We've tried to tweak the usual formula a little to make it more relevant for Photo Ephemeris users:

  • There's a 3D visualization, which makes things much more intuitive than looking at pages of numbers or labelled diagrams
  • You can relate the field of view to a range of azimuths or altitudes - particularly useful if you want to check quickly whether a given lens will accommodate the full moon at a certain altitude, while still allowing you to compose your shot with the horizon in view (to give just one example)

The tool is free to use and works on both desktop and mobile devices. It'll automatically save your settings in your local browser. In addition, there's a useful guide available showing you how to use it.

We'll be expanding this in the future and also incorporating some of this capability directly into Photo Ephemeris Web. If you have any comments or suggestions, please let us know.

In the meantime, Happy New Year!
