  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Gate shadow - On OLPF1 & 2?

Some lenses exhibit this worse than others... good thing is that the new OLPF system has a new piece to help correct this for the most part.

That should be front page news! :)
 
This is killing shots for me on constantly when I am opping the movi. Really frustrating. I am wondering how people are making out with the new OLPF system. Any better?
 
Hey Jack, two posts above yours Jake quoted Jarred saying that the swappable OLPF system reduces this issue (although it doesn't get rid of it entirely.) You have the camera now, so you may as well switch to the swappable OLPF system anyway and see how it does.

I had upgraded my Scarlet-X to Dragon recently (included the new swappable OLPF system), and this was still an issue with backlights / hair lights that were gracing the edge of frame on a low-budget feature. Nothing an eyebrow couldn't fix quickly, but still kind of annoying.

Nikon mount as well, so it seems like it's still there under certain circumstances.
 
NOOoooooo... And something tells me it'd be more predominant at 6k/1.2x crop...

Thanks for the heads up Anthony.
 
Today I swapped out the Nikon mount and put the Optitek back on the Dragon. I was not specifically looking for the gate shadow, I've kind of accepted it at this point, but I didn't see it at all. This is totally anecdotal and I wasn't trying to get into situations that create the shadow, just shooting as I normally do. Now as I watch the footage I am not noticing it, even in situations where I would expect to. Again just anecdotal, but I thought it might be interesting to somebody.

BTW- I have the fixed OLPF
 
What is the "fixed" OLPF? Is that the whole interchangable system as a whole? Or the Low Light Filter ver. 2? Or Skin Tone?

I just got my Dragon yesterday with the Interchangable Low Light 2 filter, and I get this awful thing when lights are just out of frame.

What mount do you have? Nikon mount is the worst for gate flaring. I use some flocking paper for telescope to lower the ugly flair effect.
I'm going to test the new OLPF gate to see if the flaring artefact is "for the most part" corrected as told by Jarred.

Doesn't seem to make much of a difference which OLPF you use, I had the issue sometimes on the skintone one and now on the low light OLPF under certain circumstances. these are some stills from a run and gun shoot yesterday when we took my brothers new puppy for a walk, as you can see....gate shadow quite clearly visible with the low light OLPF, lens was a canon 24-70mm:

here's the corresponding video to the above shots:


I dont really find the gate shadow issue a problem, as its quite apparent on the LCD screen while you're shooting and it really only ever occurs when you are shooting straight into the sun at weird angles.
 
I thought I saw a gate shadow in the film "A Most Wanted Man" which incidentally people should take the trouble to see. John LeCarre and Philip Seymour Hoffman at their respective bests. I saw the shadow and got all excited and said to myself "Ahhh -- Shot on Dragon." then I find it was shot on the Alexa.

For myself, I think I could learn to avoid or live with such limitations when the rest of the camera systems are so good. I wonder if I should disharmonise two SI2Ks in SI3D and splice two adjacent frames together for faux 4K cinemascope?

I don't think that flagging is the solution here, because most of us love lens flares, and every other commercial I shoot needs lens flares :) And I love those, which are created right outside the frame, which fog the picture a little bit.

I have the Canon Titanium mount. Tried with several Canon EF lenses.

But what is the "new" or "fixed" OLPF gate? I got my camera yesterday from the upgrade, so I guess I have the new one? Or is there yet another fix coming for this in 2015?

I hope it's just the edges of the filter container or something, which need to be beveled or something in a future fix, but who knows.

No need to post still frames from me. I have exactly the same flare as everyone else, who's posted frames here.

I have never noticed this on any of my Nikon DSLRs. How do you replicate this?

The problem with the Nikon mount from RED is that it's much more prone to flair than the PL for example. There are more shiny surfaces than on other mounts.
Half cut flairs is for me really disturbing. Not the kind of welcomed milky lens flair.



Dragon OLPF v2 (non swappable).
 
I must take some of my critique back, as I tried with my matte box and it's flags. It completely goes away when you use the flags, and you can still shoot lens flares to your hearts content, because the issue only happens with the rays which are hitting the lens from outside the frame. Essentially it seems, that you can shoot as much lens flares as you want... except you can't get that milky flare, which lifts the black-levels (I love that one, but I can live without it).
 
is tweaking the mount design a possibility?
