Hi,
Does anyone know if this exists, negative double 8 film in either color or B&W. So far I've found only reversal type. Thanks.
Negative Double 8
Moderator: Andreas Wideroe
I have processed 'reversal' b&w film as negative, and it seems to work.
Electronic reversing is certainly easier than doing it chemically. I suspect there is an increase in grain - it is difficult to tell because it does not look much different to film I have processed and reversed in the past.
As all negative b&w films can be reversed it would seem a very expensive process to make specially make reversable film.
All the above is a guess. maybe someone knows if there is really a difference between Kodak Super8 Tri-X and the 35mm roll of Tri-X one buys for a still camera?
Agfa sell special b&w 35mm films for reversal, but are they just ordinary b&w films that are processed in a special way as the price includes processing by Agfa?
I think I am getting into conspiracy theories now :roll:

John Schwind directs how to determine exposure for B&W reversal Double 8mm shot to be processed as negative. There is a change of exposure required. I've done that, processed it as negative then printed it again on the same stock and it comes out great.
Someone once told me that the silver halide crystals in reversal stock come in different sizes. The large ones react to light more quickly than the small ones. The large ones are on top and the small ones are on the bottom. The large ones are what you get when you process as negative. The small ones are what you get after bleaching out the large ones and exposing the small ones then developing them.
This is the work being done now in my studio. My web has pictures and text about my progress. Pictures of the Morse film dryer were accidentally deleted, but I put up a new one of the larger drier machine. New pictures will be added as I go along.

yes there is. the main difference is latitude and grain, and stills have more latitude and more grain. there are also differences in how they react to pushing and pulling and a bunch of other things. there are also big differences between the b&w negative and reversal stocks as well. they simply have different response curves since negative and reversal processing produce very different gammas.wahiba wrote: All the above is a guess. maybe someone knows if there is really a difference between Kodak Super8 Tri-X and the 35mm roll of Tri-X one buys for a still camera?

If the differences are as great as people say then they are obviously different films. As film is originated on big rolls, and then cut down it is likely to become an uneconomic product to make as it could be years before a manufacture sells a roll, with all the storage costs to consider.
So long as there is 16mm film there is likely to be 8mm as they come off the same stock and dito so long as there is 35mm. But if the ciema industry goes totally digital, TV also then the market for commercial cine film dwindles to nothing.
I do not know how long this might take, but I expect it will be sooner than people might appreciate.
With my manufacturing hat on it seems there will be a market for small film makers in the context of coating the plastic rolls and punching the holes. Fortunately the same digital technology that eliminates film makes this easier. So when will the cottage industries in cine cameras, cine projectors and cine film stock start up?
