Frame Grabs From Tests On ...

Ilford SFX200 Near Infra Red Film

They were shot in Devon UK at the end of my garden, around 9:30 am.


They're the centre exposure of runs that go from -2 to +2 stops at half stop increments.
The unfiltered shot was rated at 100 ISO which is the recommended rating and it seems to be spot on.


The red filter was a 2 stop loss so film rated at 25 ISO for those tests.


The SFX was shot as a 4 stop loss as recommended, it may have been marginally less maybe 3 2/3 film rated at 6 ISO.


Base T stop was 11 unfiltered with a 45 degree shutter to allow for exposure variation with shutter.


So 5.6 with red and 2.8 with IR which was a gel in the gate of my 435.


The tests were shot on a Cooke 32mm and NO compensation was made for focus shift.


Unfortunately rain clouds moving in killed the black sky/white clouds effect, the weather is perfect for more tests at the moment but my kit is in transit to my next shoot.

Sponsorship of CML

CML is maintained mainly by sponsorship, this sponsorship enables us to continue to grow and provide a continually expanding information service to all those involved in cinematography.

JPB of Aaton came up with the original suggestion of basing sponsorship on $1 per member per year. We have now outgrown this as we are too big now to justify this level of support and it's been fixed at $2,400 per year for the last 5 years.

For this a sponsor gets a logo on the web-site header which appears on all 3,000+ pages and a tag on every message posted via CML.

We sent out 33.4 million email messages in the last 12 months. They also get access to private mailing lists that we can set up for their specific requirements.

Our current sponsors are listed below please mail me if you want more info.
