    Just a basic IR OLPF test with my Red Scarlet Dragon when I visited south of France late last year.
    This was with KipperTie's IR-OLPF.
    Got around to getting something finished.
    No hard curves or anything added to the grade. Left it quite natural apart from desaturating it all.
    I did add some post grain to help aid towards reducing nasty banding. This was a test also.

    I was testing:
    • How the light reflects off certain materials and objects
    • Lens flare
    • Choice of lens
    • Filteration
    • Timelapse
    • Conditions of sunlight for IR capture

    Here is the Vimeo link:

    Let me know what you think on Vimeo, share, like, love if you enjoyed it.

    4K update: Here is the link on youtube:
    Untitled IR 4K

    Very awesome Phil.

    was this the full spretrum IR, or the IR only olpf?

    This was just the IR only version. I have both but for ease of use and for what I wanted to test I just used the IR Only.
    The full spectrum is handy if you wanna film a bit of IR and then a bit of normal visible light tho.

    I haven't tested the difference between Red's IR and KipperTie's sadly.

    Lovely images, well done.
    You had mentioned, that you added some grain to deal with banding in the images. Unfortunately, banding is a fact of life with B/W images and some use grain as a way of dealing with this problem. So, instead of adding grain/noise, I suggest you look at the Debanding tool, offered by Sapphire. It is available on number of platforms, including OFX variety for all grading platforms. It is a bit of work, but the result can be very good.

    Hi Jake,

    thats really helpful. I did try and search if there was something out there that could help with it.
    I will certainly check Sapphire out.
    I appreciate the tip.

    The Tiffen DFX OFX plugin has a deband tool.
    And offers 16bit/channel processing.


    Do on-lens diffusion filters help (black pro-mist/etc)?

    Unfortunately it's the nature of low image precision, which contributes to visual banding. Usually, color images have enough precision to hide most of banding, but removing color will display it in full. So, unfortunately, there is no optical substitution for high bit depth. Uploading Prores may also help. Uploading H264 and letting Vimeo do another transcode from 8 bit image is also problematic, especially for B/W image with skies.
