RED Addresses V-Raptor Picture Flaring Challenge with Flare Guard Repair



Shortly after RED’s new flagship cinema digicam, the RED V-Raptor hit the market, digicam operators began complaining a few sensor flare challenge, which emerged alongside the road that stitches two Raptor picture sensors collectively. Crimson has addressed this challenge by providing a flare guard, which can filter out any flaring that emerges earlier than it hits the sensor.

As cinema cameras develop into increased in decision, digicam sensor designers have begun stitching two picture sensors collectively in an effort to take in extra mild 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 difficulty crept up.

The difficulty is prompted when mild 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 situations the place the best lighting situations are coupled with sure lenses that are likely to solid flares into the picture.

Initially, RED CEO and Hearth Chief Jarred Land said that the problem wasn’t seemingly sensor-related since each Vista Imaginative and prescient sensor Crimson has launched would have had the problem if it was.

Land’s first impression was that it was most certainly an “optical challenge with the adapters used with sure lenses that may trigger uncommon stray mild to bounce at excessive angles sweeping throughout the sensor. That preliminary impression has been born out throughout RED’s investigation and testing.

Digital camera operator Phil Holland, who additionally capabilities as a moderator on the REDUser boards, echoed this analysis by stating that in his testing, this flare challenge doesn’t have an effect on simply RED cameras.

“I can say safely by my very own testing relating to this specific artifact,” Holland wrote, “this stretches throughout not simply RED cameras, (and) it seemingly is taking each time and experimentation to give you 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 digicam operators deploy finest practices equivalent to 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 digicam 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.
