PAR vs Compact

Recommended Posts

Compact has 96 footcandles at 45 feet on full flood


PAR has 135 footcandles at 45 feet on full flood


I found this information using the Arri Photometric calculator - and you can too: http://calc.arri.de/calculator


The reason, I think, is because the Compact has a wider beam angle (61-degrees) vs. the PAR (52-degrees).


The PAR is the more concentrated source, even at flood.


This smells like homework.

People really hate it if it’s homework. don’t they. Or perhaps they just need to point out that it’s homework. I wonder why that is? Does it bother you that much?


Doesn't really bother me, but I find learning what something is called (Photometeric Data) helps one remember it for future use.


Now chances are that I answered the specific question, the OP didn't actually learn anything - I am hoping he will follow that link and play with the program, learning about photometric data in the process.
