  • 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-M Monochrome

The IR filtering and OLPF are one and the same item currently? ie. the part in the rubbery frame behind the metal retaining plate? I guess personal experimentation with that is frowned upon, and you'd lose the OLPF and gain artifacts as a result...

That is correct... the OLPF has an IR filter laminated into it. You can get a feeling for an IR camera by taking that filter out... go ahead and try it. its not really the same, it doesn't let all the IR through, and you will get some nasty artifacts by loosing the low pass filter along with it, but it will give you a taste. It's pretty cool.

Why do you say personal Experimentation is frowned upon? I wouldn't have a job.. and most of our products wouldn't exist , including this camera, if personal experimentation didn't exist :)
 
Only that I don't want to be that guy suggesting everyone take their cameras apart... warranties are valuable things.

You can go ahead and guess whether I already did this though ;)

What is the market for IR cameras? It is wildlife filming (night)?

Ha. I remember asking about IR filming possibilities with Scarlet back in 2009. I think this was the first question I asked about Scarlet. My account was banned shortly after because I didn't use my real name.

Anyway, in my case I wanted to use it to shoot in a situation where alerting other people to our location would be very detrimental to the work.

I think most of the people using IR use it for documentary type shooting. I could be wrong though.
 
Back on topic - where does the increased native ISO come from? Is it removal of the colour filtering, other factors?

Is Redcode unaffected, or is it tuned specifically to this application?

Both.. loosing the color filtering and some sensor tweaks.

REDCODE is tuned to this application. There is an alpha RCX-pro being used in the field that already processes it. Rocket support however wont come for awhile since that requires a Rocket firmware change.
 
Jarred, could this camera be converted to IR, like "Infra"?

I was thinking the same thing mate. With a native ASA of 2000 that really opens the doors to some gorgeous IR motion shooting. It's time to experiment!
 
Surely, if you wanted the best b&w output from the colour sensor, you could get the sharpness advantage simply by not debayering (and you might have to make a few minor adjustments). Am I wrong? You wouldn't get the ISO advantage of course.
 
Wow! I'm deeply impressed by this.
Just shot a project in b&w and it came out beautifully.

One thing you will not be able to do with this camera though is processing the channels differently in post to get chroma dependent luminance values. So you have to go back to the classic way of adding color filters to the camera while shooting. :laugh:
 
I don't claim to understand all the technical details, but the removal of OLPF makes moire more likely, does it not?

IIRC there was a lot of discussion / drama about Nikon D 800E for this very reason when it was first announced. Have Red tested the Epic Mono by shooting in conditions which would induce moire to see if it is any worse than the Epic?

I think your confusing the discussion about a normal camera with the OLPF removed to see the effects of IR , with the discussion of the Monochrome camera. The Monochrome camera has an OLPF... to avoid Moire.

And our IR cameras that we built have a OLPF as well, they just have a different OLPF that removes the IR block.

Which reminds me.. way back 6 or 7 years ago when we brought up the very first sensor prototype in a box that could turn on it didn't have an IR filter on it. the 2nd thing we shot was a pair of Oakleys.. and it was pretty cool... it shot right through the plastic frames. I wonder if I have any of those images around.

I remember that. I think Brook posted a picture of the see-through Oakleys.
