STEARMAN PRESS SP-645 is a accessory for analogue photography and film handling. The card is based on the current manufacturer and supplier specifications, without unverified review claims. The daylight balance suits outdoor work and flash.
Best uses
It is intended for a controlled analogue workflow at home or in a small lab. Match its dimensions and working range to your film format and processing setup before ordering.
Practical notes
I recommend checking the item immediately after delivery and keeping it clean and dry between sessions. For precision tools, compare the reading with a known reference before critical processing.
