ABOUT INFRARED

In addition to incredible resolution and frame rate options for standard color imaging, Back-Bone’s ‘Ribcage’ camera modifications allow you to shoot in infrared as well. Our cameras all feature a removable IR-Cut filter which can be replaced with one of our Cold Mirror filters for dedicated infrared imaging. You can also use special ‘NDVI’ filters and lenses to image in specific wavelengths such as blue and NIR in order to monitor crop health from drones. Leaves and vegetation typically reflect a lot of IR, so they appear bright white when imaged for a really unique look. (Typically we convert recordings to black and white in post as the color images look very pink)

Remove the IR blocking filter from your camera if you’d like to perform ‘full spectrum’ imaging, however, focus can be soft looking without special ‘IR-corrected’ or ‘Day & Night’ lenses. Infrared is typically blurry when visible light is in focus, resulting in that softness. An ‘IR-corrected’ lens has special optics to allow visible light and IR to be in focus at the same time. Those lens types are typically only available in CS & C-Mount, another great reason to use our gear!

We recommend using a Cold Mirror filter when shooting with ‘normal’ lenses i.e. without special ‘IR-corrected’ or ‘Day & Night’ lenses. Cold Mirror filters completely block visible light and only allow IR into the camera. You can also use an IR illuminator for night vision in the dark. On the Ribcage RX0 you can set up your own custom picture profiles to get exactly the look you want. Certain lenses may not be able to focus to infinity in infrared.

Pro Tip: Cold Mirror infrared filters are available in our online shop.

SHOOTING THE MOON

GoPro probably didn’t have this in mind when they designed the Hero3+ ! We finally had a chance to test out the Ribcage on our Telescope. These images and the video below were taken by attaching a c-mount to 1.25″ nosepiece adapter to our Celestron C6 750mm Newtonian Reflector telescope. No lens was used on the Ribcage. It’s great to be able to see everything through a field monitor and not have to peer through an eyepiece. We can achieve additional magnification by using a barlow, however we didn’t have one when this was shot.

RIBCAGE: NIGHT VISION

Some sample footage shot at night with the IR-Cut filter removed from our Ribcage Modified Hero3+ Black. Shot with an IR corrected 4.5-13mm CS-Mount. The default look has a purple hue, but tinting or desaturating the footage will easily give it the traditional night vision look as demonstrated in the video. Light source was a small IR LED panel powered by a nine volt battery.

RIBCAGE: INSECTS UP CLOSE

We recently had a fun evening exploring the insect exhibit at the Canadian Museum of Nature and had a chance to test out some new high-res glass from Computar. All of this footage was shot on a Ribcage modified Hero3+ Black with our new Computar 2/3″ 16mm C-Mount and 1/2″ 25-135mm C-Mount. A big thanks to the Canadian Museum of Nature for granting us access! www.nature.ca
