Brady Hall Posted January 23, 2012 Share Posted January 23, 2012 Hello everyone, I am shooting a short film on 16mm B&W KODAK TRI-X Reversal Film 7266, I was curious on how to use my Dslr as a light meter. With the film speed at 200, shooting at 24fps, what would I set my Canon Rebel t1i's shutter speed at to expose correctly? Thanks, Brady Link to comment Share on other sites More sharing options...
Premium Member Adrian Sierkowski Posted January 23, 2012 Premium Member Share Posted January 23, 2012 1/48th (or 1 50th or 1 60th all relatively close) assuming a 180 degree shutter... But, of course you should know a DSLR's exposure is in no way a comparison to film, least of all reversal film.... and you would be much better off spending the $200 or so on a real light meter, or finding someone's to borrow.

Ari Davidson Posted January 23, 2012 Share Posted January 23, 2012 ^ What Adrian said. An entry level light meter is worth it's weight in gold. Seriously. I used a Sekonic L-398 throughout school, and almost a year after I got out. Plus, any camera just gives you reflected readings, to some degree. Separate yourself from the crowded DSLR pack, and get a light meter Link to comment Share on other sites More sharing options...
M Joel W Posted January 23, 2012 Share Posted January 23, 2012 (edited) Tri-X is notoriously hard to expose and a third stop slower under tungsten than under daylight. In theory the above (1/50) will work (although some 16mm cameras have 1/60 shutter speeds or finders that eat 1/3 stop of light), but I agree--just borrow a meter. Edit: Re: the above answer, there are lots of us in the dSLR crowd who use meters, I'd like to think most serious dSLR shooters use meters.

Brady Hall Posted January 23, 2012 Author Share Posted January 23, 2012 I am trying to get a hold of a light meter, as I have used them on my other 16mm films. I am just making a 5 minute short for class, so I needed a way to measure exposure with a tool I had. Thank you all for your help, I hope to afford a light meter soon.

Kip Kubin Posted January 24, 2012 Share Posted January 24, 2012 Grab a Gossen Luna-Pro off ebay Got this tip from Roger Deakin's forum. Great Cine meter..however, it will be used...so check it's accuracy...local cam shop or friend with a Sekonic. But mine is spot on and is way faster and easier to use than a newer digital model.... you can adjust for filters and quickly calculate over and under for any speed of filming @ 180 shutter. I tried to use my DSLR for a film light meter...the readings were really off compared to my Gossen and the internal meter in my Aaton.... so I just trusted the meter and the results were and have been perfect.

Brady Hall Posted January 24, 2012 Author Share Posted January 24, 2012 I bid on some light meters on eBay, specifically the Gossen Luna Pro as Kip mentioned. However, I do not know if I will get one in time. You guys convinced me to use a light meter, so I saw a SEKONIC FOOT-CANDLE LIGHT METER for rent (8 dollars a weekend, which is the length of my production.). This should be sufficient, yes?
