Quartz halogen lighting v tungsten

[Paramount bokeh]

Thanks Bruce.

Interestingly, I found this in the Mole archives – I managed to identify at least one of the lights Hurrell was using in a shot (type 410) and from the specification provided by Mole, it appears the colour temperature to be around the same as tungsten quartz, which I guess means they too were using lights at that temperature (from what I can gather they just used whichever lights they could lay their hands on when required to get the shot they wanted)...

Anyone agree?

I could shoot like George if I had his models! (At least I would have fun trying...)

you will never get any decent focusing from quartz lights.
their main use is bounced or through a frost filter,
meaning you can light large surfaces, and/or bring the shadows up to
control your contrast ratio.

if you are looking for 40-50s type of light (main source of illumination), you will need something
focusable like a par or fresnel. and those will never be quartzes.

... and those will never be quartzes.

Why not?

Tungsten is a metal used for filaments. Quartz identifies a type of glass that resists heat.

Roger Hicks wrote a book a few years ago (out of print but available used) where he and a colleague "reverse engineered" shots by Hurrell and other Hollywood greats, and then duplicated them with strobes. Hot lights were used in a very few cases. He pointed out in the book that when you're trying to go for the '30s look, you need to remember -- as has been said above -- that film was different (ex., a lot of ortho was used) and lenses were different.

Good luck.

Why not?

we might have a misunderstanding here.

The term of quartz usually refers to
open face lights (at least here in europe) like blondes for example, which are not well focusable.
these would be tungsten light sources

technically speaking, pars as well as open face lights may use what are called: tungsten halogen quartz bulbs.
they are balanced to 3200K. their high temperature
operation requires quartz glass.

Tungsten generally refers to 3200K lights, as opposed to fluorescent or HMI lights.

OK. It's just a terminology issue. Thanks.

What did you think blue filters are for?
