We have designed the BERSPEED developer to achieve both high sharpness, a wide grey scale and to give the ability to push film.
When film is used at its rated sensitivity, BERSPEED provides images with full shadows and highlights that are not burned, even in high contrast situations.
BERSPEED is a powder developer. It is recommended to dissolve it in demineralized water for best results. The prepared solution has a shelf life of 6 months.

Push processing +1
Pancro400 @ 800 iso
We recommend increasing the development time by about 30% for films that are pushed by one stop and developed in BERGGER Berspeed. For example, for a Bergger Pancro 400 film exposed to 800iso, the recommended development time is 10'50 at 24°C. In this example on a Bergger Pancro 400 film in 35mm the grain remains fine and the contrast is contained.

Contained grain at very high sensitivity
Delta 3200 processed in Berspeed
The BERGGER Berspeed developer makes it possible to obtain a contained grain and a wide range of greys in high sensitivity, as here with this example of the combination between Ilford Delta 3200 film (in medium format) and Bergger Berspeed.
