FOMA 200 with New55

It was bad news when we learned that EFKE was going out of business. After the long and expensive trials of that emulsion with New55 it seemed we had to start again, but since that time we have qualified at least two potential 4x5 negative materials which consist of cubic-grained single layer emulsions in the 200 to 400 speed range. Some decent results were obtained with the Shanghai 100: This gave us a result not far off the rated speed and a thin but very scannable negative. Tri-X was next, expensive as it is, and produced a sharp, high contrast result and a speed of about ISO 200. In this photograph, shot by Sam Hiser at New55 HQ in Ashland, MA, FOMA 200 was used. It works but is very sensitive to exposure seen here and on some other negatives that I have looked at, and the curve is a very strange one. Two minutes of development time at room temperature still results in a lot of solarization. FOMA 200 is a T grain emulsion with a fairly soft gelatin, and for that reason the positive print (not shown) is darker than it ought to be. It might be possible to re-balance the positive and the negative by tweaking the developing reagent. We had previously tried other T grain emulsions and found the positives to be far too dark.
