  • 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 :)

Epic flare issue solution

Some adhesives dry up and leave a nasty powdery mess after a few years. The adhesive in gaff tape is one of the worst. It happens with masking tape and electrical tape adhesive tends to turn to goo. Foam also deteriorates with time. In camera heat is likely to accelerate the deteriorization. I am concerned about just how "permanent" either of these fixes will be and how big of a mess the deteriorated adhesive or foam could make around the OLPF in a year or so. It might be best to remove and replace every few months.

I would like to see RED offer a solution that combines the benefits of Adam's and Douglas' solution. It would be great to have a little insert that is lined with Adam's telescope material but slips into the sensor throat and is pinned into place by the lens mount. I've attached a rough drawing of what I mean. The red represents the camera sensor.

Hey Julio.. You can make that exact thing out of a whole piece of flock.

You dont have to remove the backing of the sticky stuff on the flock and just cut that out with a scalpel.

The flock is quite solid and slides down the side of the metal along side the OLPF.

Someone just needs to make a stencil!

Interesting.
 
FYI, y'all: the telescope flock material is of very high quality and unaffected by (reasonable) cold, based on my experience. I have applied the flocking to parts of several open truss telescopes that are in remote observatories at 5-8,000 foot elevations. The telescopes are regularly exposed to cold nighttime conditions during the winter and get somewhat cooked during the summer (the observatory buildings are not air conditioned). No problems after over five years. No guarantees here, YMMV.

Thanks to Adam Lubkin for sending me one of his Epic cams for this research.

If you need to rent an Epic, you might try him - he's tops.
 
Just wondering if shooting HDRx is a solution to the flare? That is, if we check footage on set and see the flare and then switch to HDRx, will the flare still be there in a more benign way or will it dissappear when the A and X track are combined? Anyone know?

It will still be there, when it's there it's there!
 
Has RED come back with any solutions or answers to this issue? Just curious?

I'm happy with the flare, I liked it on my 435 and 235... I like it on the RED.. (but when doing clean flare free plates I'd like it gone)

aaaaaaaaaaaanyway.. sounds like you guys have a soltuion for it anyway. :)

Who says so?
The last thing we heard directly from RED about this issue was:



I know that Doug's solution is approved by RED but this doesn't make it the official RED solution.

OK.

You win.

I deduced this by having watched this thread and Doug's video, and waiting for Doug to post only after having spoken to Jarred. But I am probably wrong.

I may be interested Rick. At minimum I'd love to see how you do it.

Rick or Dave,

If you end up doing this, can you walk this into RED and have them tell you it's OK as an option to Doug's option?

Doug Underdahls solution is the official RED solution.

I hope that is not the case. Although it may eliminate the flare, I don't like the idea of a loose piece of foam floating around my sensor, especially during moving camera work. It also looks like it could complicate keeping the sensor clean.
An official, semi-permanent solution direct from Red would be ideal so producers don't need to put a strip of foam on their equipment checklist.
 
The only person who can say it is the official solution is someone from RED. I can not claim that. From what I understand Dougs solution is approved. That's it. If it's good for them it's good for me.

If you have a better idea, you should contact RED and propose it to them.

If I come up with something I think is better that is what I would do.

Sorry, I just reread my last post and it sounded very rude. I typed it quickly on my iphone during a quick lunch break on set. I very much appreciate Doug and Adam taking the time to explain their solutions. They both seem to solve the problem and it was very generous of them to share it with the community. Especially considering Doug doesn't even own an Epic.
While these are perfectly acceptable solutions in the interim, in my experience AC's complain about anything and everything that they haven't seen before, such as mini-BNC, mini-XLR, Red Shoulder Dovetail, IR contamination, etc. Once "flare flockers" start coming loose as AC's try and clean the sensor, they will start complaining, and producers will listen.
I only say this after years of defending the RED ONE as if it were my flesh and blood. I'd rather not deal with that again over such a minor issue.
 
Ok...here's one for ya...ANYONE ever see this ? This is what i think might be a reflection of OPLF--but i don't even know what i'm talking about when i say that....but i heard enough talk about it to be dangerous...Anyway, i see this on images where the light is just right...on this image i'm using Tungsten LED lights....but i also see the same image on some shots where i have HI contrast...dark on lower half of image and then looking up to sun underwater...It's ALWAYS the same image...to me it looks like a big ladder hanging down in the middle and then there is some kind of box to far right.....

R1mx; Shooting 4k 30fps.....and I have NEVER seen this before...only recently (this last shoot).
