What is freemask?

freemask is the quickest and most exact solution to produce accurate and homogeneous cut-out masks in studio routine. Even smallest structures, details and transparencies are perfectly reproduced.

The mask is created during the picture taking process which reduces the amount of cut-out work after production to a minimum and allows for workflow of highest quality at a most efficient level. freemask was developed in cooperation with the schoepe GmbH.

All info about freemask can also be found in our flyer. (PDF, 215 KB)

How does freemask work?

With the help of the continuous exposure setting of your camera and the freemask transmitter, two exposures are automatically made per shutter release: during the first exposure the motif is lit (1), and during the second exposure only the background is lit (2).
This backlit shot is used to create a pixel-exact mask (3) at postproduction.

What do I need to use freemask?

You need Hensel flash units with a freemask receiver (integrated or external), the freemask radio transmitter, and a digital camera with continuous exposure setting (min. 3 exposures per second).

These flash units feature integrated freemask:
Expert D
Integra Plus
Cito 500
Nova D / Nova DL
Porty L
Tria 24 SF

The freemask transmitter is available for triggering of the units. Furthermore, you can use the freemask radio set (1 transmitter and 2 receivers) to turn older Hensel flash units into freemask-ready units.

You can use the freemask flash equipment for normal applications, if no cut-outs are necessary.
