Infrared with Raptor or try to source Kippertie OLPF and use DSMC2

[Jeffrey Wright]

Hey guys, trying to figure out options for a possible Infrared conceptual art project. Still trying to figure out the directors vision but was asked to research Infrared and am a little confused.

We've been shooting primarily on Raptor VV and s35's. Part of the project has been shot with HAL 250 deg (I think it's the 250 as it's not my part of the project) super wide angle lenses so I'm assuming it will be impossible to source rear IR filters for it. The other lenses are EZ zooms and Fuji MK zooms.

It seems the easiest option (if it's without the HAL lens) seems to shoot on a DSMC2 and try to source the Kippertie color science IR OLPF with IR filtration in front of the lens.

Does just shooting with the IR OLPF and no external IR lens filtration work or do you need both?

Does shooting with no IR OLPF and just external IR lens filtration (we could use the Raptors we own) work or do you need both?

Really, really appreciate any help on this!

Here my tests. Start @ 19sec.

If you use a regular olpf and cut light you would have to cut a lot of light (probably beeing at 25600 iso in sunlight) to get a bit of effect.

I still have my Monstro (to sell) and the IR OLPF ;-)

Just to clarify terms, if you want to shoot in IR spectrum (rather than visible) you're after IR Bandpass, not filtration.

Most modern lenses have varying degrees of UV and IR filtration, but it will depend on the lens. Generally older and "worse" lenses will be better for UV/IR shooting.

In your case - I would focus efforts on finding a DSMC2 IR Bandpass filter to use.

I have not used the kipper tie one https://store.kippertie.com/product/false-colour-olpf/

I had Kolari Vision do a custom full-spectrum conversion on a Monstro body and they made some custom IR and UV bandpass OLPFs for varying wavelengths. If you crave more creative control over the IR in the image that may be a way to go.

Just incase.
The regular OPLF filter cuts out IR and UV and cleans up some of the other light striking the sensor.
You can add a IR only filter in front of the lens with the regular OPLF filter still in but it will not give you the best results.. As the OPLF FILTER will be doing its job and still cutting most of the IR light.
You need to remover the OPLF filter and replace it with ether a full spectrum... (all light including IR ) OR a IR filter which would allow only IR to reach the sensor.
Cheek Kippertie.
I have both of the full spectrum and the IR only and love each for different reasons. They work as advertised.


Just as a not here. When ever I have used the Full spectrum or only IR from Kippertie on my Monster.
When shooting people it is possible to see their blood veins pretty visible on some people with fair or very light skin, Also be aware that some clothing or articles of clothing you may actually be able to see through when using IR. You should always test before the production as you would not want to get to post on a commercial shoot only to notice that your main cast is almost not wearing clothes...
If you use a full spectrum you can buy a 720 cut filter to get rid of all the other light so the filter will only allow light close to IR to hit the sensor... OR you can in post make some of the adjustments AKA desaturation and it will take on a more B&W appearance .

Or get an EVA1 for this purpose

This was from a shoot that I had to scrap original concept because we got clouds and rain instead of blue sky but still wanted to test the IR Chrome filter from Kolari. This is EVA1 in IR Mode. Also including version that doesn't have grain just in case you need to see fidelity vs stylized. Really the blue sky was what would make this effect pop, buy alas the model was a good sport and we filmed this for fun.

This is using the 720 on EVA1

I forgot Eva 1 could do this. Very nice images.
I'm actually scheduled to film with one for a couple of days next week.
Intrigued to try this out.

Hit me up if you need any info. I had the camera for a while before I finally messed around with it. Kind of breathed new life into the camera for me. Not that I will use IR mode much but it's there if I do need it.

Thanks for the offer Steve.
A client of mine has one that I have shot with a few times but I admittedly overlooked some of it’s features particularly the IR.

The shoot I was going to use it on is going Varicam LT instead but I might still try to further test out the EVA soon enough.

Panasonic might still consider getting back into the cinema market.
Their cameras had their issues (like anyone else) but they still made some very good cameras.
