About a year ago I tested Dixactol vesus Pyro Rollo, both with Efke 25, 35mm film, both of the same subject matter = glass.

There was no contest! The Dixactol negs were grainy; the Pyro negs looked like they were etched in terms of sharpness; when printed to the same size the Pyro negs were far superior, no grain in the highlights, extremely sharp and with an incredible scale.

I shot another scene thereafter on Efke 25, processed the film in Pyro Rollo and made an 8X10 print. At the same time I shot a 5X7 neg on Bergger 200, processed the film in Pyro Rollo and made an 8X10 print. To the untrained eye there was no difference... I have never touched Dixactol again!
