FILMOMAT F-stop Darkroom Timer


The Filmomat f-stop darkroom timer is designed to provide the best possible user experience in the darkroom. With a minimalist design, it offers a streamlined and straightforward workflow that is easy to use. We believe in focusing on the essentials and avoiding unnecessary complexity. This darkroom timer features an intuitive interface that is easy to navigate, without any fancy or distracting features.

The premium rotary switches offer exceptional haptic feedback that complements the analog setting of the darkroom perfectly. The darkroom timer is built to last, with a housing made from CNC-milled black powder-coated aluminum. This high-quality material not only provides excellent durability but also adds a sleek and modern look to the design. All labeling on the timer is CNC-engraved as well.

This darkroom timer is an f-stop timer. This means that the exposure time is not changed in second intervals (1, 2, 3, 4 sec) but in f-stop intervals (1, 2, 4, 8 sec). The exposure time can be changed in 1/2, 1/3, 1/6, and 1/12 f-stop intervals. In test strip mode, a test strip with 7 segments (-3 to +3) can be generated automatically. Again, the interval between the segments can be selected between 1/2 and 1/12 f-stops. While the test strip is made, a LED bar conveniently indicates the current position of the exposure.

Test strips can be generated in two ways: Incremental or single test strips. In incremental mode, a base exposure is followed by 6 additive exposures. After each exposure, a segment of the test strip has to be covered up. This usually is the standard procedure for making test strips.

In single mode, 7 individual test strips are exposed after another, with each receiving the full exposure time of a final print. This is particularly useful for challenging prints, which require test strips of detail areas of the image.

The safelight and the enlarger (for focusing) can be switched on/off via individual switches. The test strip mode (incremental/single) is selected via a switch as well. During exposure, the safelight is automatically switched off to avoid influence on the print.

The brightness of the display and LEDs can be adjusted stepwise from 1-15.

A large 7-segment display is used to show the exposure time.

The timer has two connections for the enlarger and safe light. An optional foot switch can be connected to enable hands-free operation.
