PhotoView - what does it do?

There are many photometric viewers out there, but one of the most flexible and advanced is PhotoView, which is what I'll show you here. Not only does the program show you luiminaire photometry data, but you can edit the data as well.

(Other advanced functions are batch file conversions and creation of high quality images for catalogs.)

The collection of images below show just a few of the diagrams which PhotoView photometry viewer can produce from your IESNA or Eulumdat files:

Some Photometric Viewer Images and Diagrams

The images shown above are covered in more detail here, but I'd like to show you the shading images you can get when you are in the isolux tab of PhotoView:

You can see some check boxes at the above right of the screenshot, if you switch off Text and switch on Shading you can get illumination lux images (for the floor) like the one shown below:

Photometry as shading (floor)

This Photometric Viewer also allows you to see the walls of the room, like for example the West wall:

Taking a different luminaire photometry as an example you can change angle, and position of the light to see what three very narrow spotlights might give you:

Of course this is only a direct light calculation. And of course you can return to a numerical diagram, this time of the floor:

PhotoView also reads and save files in the new OXL photometric file format.
