Talk:Fresnel lantern

Optically, much of this is nonsense
At the very least, it's confused and doesn't suggest that the author understands the optical principles of lenses. — Preceding unsigned comment added by 2.101.25.119 (talk) 22:10, 29 December 2016 (UTC)

Capitalization

 * Need to make capitalization consistent. Is it "Fresnel" or "fresnel"? Isopropyl 01:56, 23 May 2006 (UTC)

 * Photograph- I recomend a change of both photographs. Photo #1 is not right side up and it is hard to tell what the luminaire looks like. Photo# 2 is hardly a good desciption of the use of fresnels in theatre and concert. I also recomend that it should be mentioned that fresnels are slowly making their way to a shelf in the museum of theatre technology. Automated wash lights and Source-Four type intruments are overtaking the fresnel with better efficiancy.


 * In my theatre we use Source 4's/Lekos above the FOH and fresnels above the stage, with scoops at the back.

Agreed: the picture should at the very least show the distinctive stepped lens. Bryson430 19:31, 16 August 2006 (UTC)

Barn doors v Harris Flaps
The article says that barn doors "are colloquially known as "Harris Flaps" in the United Kingdom theatre industry".

In 50+ years in theatre lighting in the UK and Australia I have never heard this phrase. The source for it is not authoritative. I have even tried to google it. Nothing came up. Ranko strandini (talk) 04:35, 7 March 2024 (UTC)
