| Thinking Photometrically II |
On May 29, 2001, byHeart Consultants CTO Ian Ashdown presented the "Thinking Photometrically II" workshop at Lightfair International in Las Vegas, NV. The objectives of this three-hour workshop were:
- An in-depth understanding of photometric reports, including IESNA LM-63, CIBSE TM-14, and EULUMDAT file formats.
- An explanation of the photometric measurement process and its relation to the accuracy and reliability of photometric reports.
- A non-technical analysis of lighting design software algorithms, with particular emphasis on understanding how they work and how to use them properly to produce photometrically accurate predictions and physically correct renderings.
The 46-page handout from this workshop is available here.
