UPGRADE YOUR IMAGE QUALITY

It’s not often that you get something for nothing, but now you can benefit from higher PWM bit depth output thanks to a free firmware update – no additional hardware required. 

Extended Bit Depth is available for all existing and new panels containing the Brompton R2 or R2+ receiver cards and offers several impressive benefits:

Reproduces HDR content up to 10 times darker than previously possible, without compromising peak brightness for HDR highlights

Offers two to three stops of additional dynamic range on camera

Fully compatible with our Dark Magic and ShutterSync®  features 

UNLOCK HIGHER BIT DEPTHS

With Extended Bit Depth you can unlock up to 3.3 additional bits of precision depending on panel capabilities, video framerate and camera shutter angle being used, for example, a panel running at 24 fps with a 180° camera shutter angle could offer: 

2.3 additional bits of PWM precision

5 times the number of low-end brightness levels
125 times the number of colours

ACHIEVE PEAK IMAGE QUALITY

The benefits of Extended Bit Depth are most obvious at low and ultra-low brightness levels – it brings out additional detail and nuances in dark areas of the image while also reducing visual artefacts. 

In comparison with panels not using the feature, panels with Extended Bit Depth enabled are noticeably smoother and show more detail.

A DYNAMIC ADVANTAGE

Extended Bit Depth is fully compatible with ShutterSync®  and typically offers two to three stops of additional dynamic range on camera, a massive advantage when filming an LED screen displaying dark, shadowy content.  

The additional range can also be used to achieve brighter, more realistic lighting – the camera exposure can be increased substantially when using Extended Bit Depth, making the panels, and any lighting from them, appear much brighter on camera.

“Brompton’s Extended Bit Depth capabilities were also a huge benefit on the Polestar project, as we had a lot of ambient light and reflections that all needed to be accurate. The added precision you get with Extended Bit Depth, especially on the low-end brightness levels, makes a significant difference compared to what we’ve seen previously.”
