Greg, It might be possible to load the 100' mag, shoot what you want, then take the mag in a darkroom and cut off just the film you have exposed for processing. This works best if you're shooting B/W and can process yourself. I did this many times with 36 exp. rolls with 10 or so exposures that I had to see right away and I'd save the remaining short roll for small quick shoots. You'll lose a few exposures on the roll, but in the interest of time it all works out. As for the Novatron, I think you're splitting 500 watts between 3 heads. As for f-stops, what speed film are you using? At ISO 100 with a 3 light set-up, you should get about f8 or f11 with the lights at a reasonable distance for a portrait. If you are shooting 100' rolls of color neg, you have the problem of loaading the short roll mentioned above in a cassette, and then the non-perforated roll might be a problem for the processor. You might call your lab and find out. Hope this helps.

I would like to test the camera and lights but I don't really want to blow 100' of film to do it. Does anyone know if its possible to load a 36 exp roll of film into the 100' magazine (after removing the 36 exp roll from its casing). Well, I'm sure its possible but will the camera function properly? The Novatron power pack has a switch for 500 or 125 watt/seconds. I always equated watt/seconds to light output but my light meter gives me the same reading no matter what the switch is set at. If I have 3 heads connected to a 500 watt/second power pack, is the combined output 500 watt/seconds or 1500 watt/seconds or is watt/seconds not really a measure of light output? One thing's for sure, I'm loving having this much light at my disposal. Up until now all I've had for portrait work was a couple of ac strobes that you screw into a light socket and old Kodak Sun Gun movie lights. I used to shoot at f5.6. With the Novatron lights I had to put 5 sheets of cloth over the head and shoot through an umbrella and even then the widest I could set my aperture was f16. Perhaps a bigger studio area is needed. Maybe I can convince the wife we really don't need a dining room table. Greg Fraser
