    I have had two EpicW sent back to Red due to this matter. No matter which Olpf or firmware I used, both Release build and Beta, always green hue. I had to dial between -8 to sometimes -20 tint, depending on the scene and lighting. Red is currently looking into this. I hope they can fix soon.
    For the moment, good starting point is to white balance your scene accordingly, then dial -10 tint and adjust from there.

    However, image from EpicW with IPP2 is superb once you correct it properly in camera or post, no doubt.

    Have you tried the Truecolor RED to Alexa LUTs? It corrected out or at least lessened the green tint on my Helium Weapon. http://truecolor.us/news/red-to-alexa-lut-package/

    Would you mind uploading two images, WB 5600, 0 Tint, with and without this Lut applied?

    I can provide some examples as well (if there are specific shots you'd like to see, let me know). Here's a quick comparison using the R3D posted earlier in the thread.

    Everything is left at their default settings (5600k WB, 0 Tint, 800 ISO). Click for a larger image:

    There's also an online demo of the LUT where you can try it out on some of your own images (it's lower quality though):

    Thanks John. Was this shot on Helium? I don't see very green hue. Footage out of my EpicW is way way more greenish.

    Yes, the R3D metadata says itís the Epic-W Helium 8K S35 sensor with Standard OLPF. You can find the R3D here: http://www.reduser.net/forum/showthr...=1#post1740768

    Iíve also noticed a greener cast from Helium as well (compared to Dragon) - maybe itís stronger with other lighting scenarios (like tungsten)?

    According to Red engineers there are variations in Helium sensor. Some are more greenish than others.
    Mine is definitey on the greener side. Sometimes -20 Tint to compensate. Not sure your Lut would be much help though.
