Dupont Superior 4 B&W pancromatic film UPDATE
Well the deed has been done. I coaxed myself to open the new (old) sealed can, wound a 36 exp roll and shot it outside. Developed with D76 for 8 minutes at 70 deg F and was extreemly surprised at the results. The first several inches were slightly fogged but gradually cleared up and a foot later revealed amazing beautiful negs. Very nice, clear base and great d-max. Printed on Illford mg needed just the slightest addition of magenta to make great prints. Estimated effective speed is about 150-200 using an 8 stop bracket and developing times. With old film, sometimes you win and others not. This time I got lucky.
