Q: Can I “push process” my film with Sprint’s STANDARD Film Developer?
Yes, underexposed or “push processed” film can be developed with STANDARD. Our recommendation is to advance the development time by 2 chart letters for 1 stop, and 4 chart letters for 2 stops. For example, Ilford HP5+, whose normal chart letter is “O” (10 minutes), would be moved up by at least two chart letters, to “Q” (13 minutes), if it were underexposed by 1 stop.
Please note that Sprint STANDARD B & W Film Developer is designed for optimum quality at a film’s normal exposure recommendation. While underexposed film may be developed successfully in STANDARD, the film’s contrast will increase and its tonal range will be restricted. Developing film underexposed beyond two stops with STANDARD is unrealistic and not recommended.
