What??? A question about FILM in a cinematography forum???
You will probably have to flash in camera– it is hard to find a lab that will flash a neg anymore, either pre or post shoot. I suppose they didn’t want to bear the responsibility if the results were not as expected, as well as the risks involved with the extra handling of the stock.
I always thought it would be cool if you could buy pre-flashed stock– like maybe a 10% flash. I guess the manufacturers would not want to keep the latent flash on an undeveloped neg for an indeterminent length of time– results might be unpredictible. I myself have had better luck flashing Fuji stocks but I cannot really say why I prefer them– have flashed Eastman as well.
I like the Varicon a little better if only because you can fairly reliably see in the viewfinder or VA what is really happening. It is however somewhat a more cumbersome rig than the Panaflasher– but I guess that is not an issue since you are probably not shooting Panavision.
I have not seen a Varicon in a while. You would think most Arri rental houses would stock them but I think they are actually a bit hard to come by now– so I would track one down and book it well in advance. Be prepared for at least one actor or crew member to say “Something is wrong with the camera!” when they see the glowing lens– it always happens.
