canwewin Posted November 27, 2012 Share Posted November 27, 2012 <p>Hello,<br> I recently got 17 rolls of Agfa Scala, expired in 2007.<br> I'm going to develop them as negatives.<br> Since they are quite old (always cool stored,) I was wondering at which E.I. should I rate the film. <br> I would assume rating them at 100 will be fine, but maybe I'm wrong...<br> Any suggestions?<br> Thank you<br> <br />L.</p> <p> </p> Link to comment Share on other sites More sharing options...
craig_shearman1 Posted November 27, 2012 Share Posted November 27, 2012 <p>2007 is not a problem for B&W film, especially cold stored. But since Scala was intended to be exposed as a reversal film, not sure about what ISO to use. Simplest thing is to shoot a roll with a series of exposures -- assume ISO 100 but then brack three or four stops on either side of the ISO 100 exposure -- and see what exposure works best. Then shoot the rest at that ISO.</p> Link to comment Share on other sites More sharing options...
larrydressler Posted November 27, 2012 Share Posted November 27, 2012 <p>I believe they will be fine at box speed. Many shot it at 200 anyway.</p> Link to comment Share on other sites More sharing options...
c_watson1 Posted November 27, 2012 Share Posted November 27, 2012 <p>Since you've got lots(cheaply?), start with ISO200 and try +/- 1/3 to 2/3 stop. Scala was often push processed 1-2 stops with nice results. Depending on where you're located, you can still get it processed as a b&w transparency, too.</p> Link to comment Share on other sites More sharing options...

john_stockdale2 Posted November 29, 2012 Share Posted November 29, 2012 <p>I think that the emulsion is the same as APX 100. Reversal processing is different to negative processing in that overexposure can lead to serious image loss in highlights, hence the recommended rating at 200. Which leads me to suggest that when used as a negative film, Scala should probably be exposed as if it was 100.</p> <p>Please let us know how it goes</p> Link to comment Share on other sites More sharing options...
larrydressler Posted November 29, 2012 Share Posted November 29, 2012 <p>The new ADOX Silvertone is the same/based on the Scala but on a polyester base and the emulsion was based on the APX line but what they are selling as the 100 New APX by Rollei and Kentmere. is not the same... Just related.</p> Link to comment Share on other sites More sharing options...
francois_p._garnier Posted November 29, 2012 Share Posted November 29, 2012 <p>Larry, the new Adox film is <strong>Silvermax.</strong><br> And this film is coated on a conventional triacetate base, <strong>not</strong> on polyester. I've used this film, very good stuff. Very very similar to the Agfa APX 100 film.<strong><br /></strong><br> And there is <strong>no</strong> new "APX by Rollei or Kentmere". The Rollei <strong>RPX</strong> film is made by Ilford for Maco / Rollei-Film. But it is not the Kentmere emulsion, it is different.</p> Link to comment Share on other sites More sharing options...
perry_n Posted November 29, 2012 Share Posted November 29, 2012 <p>I recently discovered I have an unprocessed roll of Scala from 2006/2007. I developed it in Rodinal 100+1 for an hour and it turned out great. It also brought back some good memories. :)<br> I imagine you'd do fine shooting at box speed and processing as you would an APX 100. The one difference is that Scala's base is clear. Since you have quite a few rolls. You can experiment with one or two.</p> Link to comment Share on other sites More sharing options...
canwewin Posted December 2, 2012 Author Share Posted December 2, 2012 <p>Thanks everyone for the replies.</p> <p>here's a random shot. <br> E.I. 100, developed in Rodinal 1:25. Pleased by the results</p> <p>Next I'll try it at box speed!<br> Thanks</p><div></div> Link to comment Share on other sites More sharing options...
perry_n Posted December 3, 2012 Share Posted December 3, 2012 <p>Nice! If you ever get tired of shooting with that film, send some my way and I'll help you finish it off. ;)</p> Link to comment Share on other sites More sharing options...
