Shortly after RED’s new flagship cinema digital camera, the RED V-Raptor hit the market, digital camera operators began complaining a couple of sensor flare concern, which emerged alongside the road that stitches two Raptor picture sensors collectively. Crimson has addressed this concern by providing a flare guard, which can filter out any flaring that emerges earlier than it hits the sensor.
As cinema cameras turn into larger in decision, digital camera sensor designers have begun stitching two picture sensors collectively with the intention to take up extra gentle and enhance picture efficiency. That is true with the Vista Imaginative and prescient Crimson Raptor, which takes benefit of the twin picture sensor setup. However final December, a problem crept up.
The difficulty is triggered when gentle coming onto the twin picture sensor would illuminate the sew line between them. This causes an annoying flare to seem within the picture, highlighting the sew line.
The difficulty doesn’t occur on a regular basis, simply in sure circumstances the place the best lighting circumstances are coupled with sure lenses that are inclined to forged flares into the picture.
Initially, RED CEO and Hearth Chief Jarred Land acknowledged that the difficulty wasn’t seemingly sensor-related since each Vista Imaginative and prescient sensor Crimson has launched would have had the difficulty if it was.
Land’s first impression was that it was probably an “optical concern with the adapters used with sure lenses that may trigger uncommon stray gentle to bounce at excessive angles sweeping throughout the sensor. That preliminary impression has been born out throughout RED’s investigation and testing.

Digicam operator Phil Holland, who additionally capabilities as a moderator on the REDUser boards, echoed this analysis by stating that in his testing, this flare concern doesn’t have an effect on simply RED cameras.
“I can say safely by my very own testing concerning this explicit artifact,” Holland wrote, “this stretches throughout not simply RED cameras, (and) it seemingly is taking each time and experimentation to provide you with the suitable design that may be mass-produced and fairly put in on the body-side.”
4 months later, RED has designed what it calls a “flare guard,” which sits between the lens and the picture sensor. The flare guard should be put in by RED, so Raptor house owners must contact RED to rearrange for set up.

Within the meantime, RED recommends digital camera operators deploy greatest practices reminiscent of putting in a matte field or lens hood, and when obligatory, an RF to PL lens adapter which is designed with correct flocking and unreflective inside surfaces.
As soon as the flare guard has been put in, RED says that the stitching flare is totally mitigated, with out affecting any deliberate lens flare that the director or digital camera operator needs to make use of to have an effect on the general picture. Shifting ahead, RED plans to ship new V-Raptor cameras with the flare guard preinstalled.
