  • 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 :)

ill add this to the original post too

That's very generous of you to share your images and take the time to upload these.
My only request is for a few 400% blowups so we can see what's going on in there.
Much appreciated.

if there is a specific one you want to see I can upload a R3D..

Yea, the Helium sensor is an amazing piece of tech!

I really can see the *magic* happening that Jarred talked about.. even with this crazy guerilla style I shot this in. A lot of my shots are soft or semi soft even. ;)

Nice Tim! Looks like you get some of those blown out bokeh's as well, have you noticed these really hard colored bokeh that's completely gone? We did some extensive testing with Helium and found that it doesn't handle highlights all too well. I heard that's what they made Log3G for but I don't like what it does to the image, it seems like you are losing a lot of highlight details. I wonder if the new color space will fix that too

I too have noticed Helium handles highlights differently. I havent figured out what it is doing yet, but I dont think its handling them poorly or not well enough. I think it handles them differently. It seems they are quite more sensitive than before. Especially with clipping. Doesn't this correlate with the noise floor? The sensor handles the shadows so much differently than dragon. You would expect a difference in highlights right?

Log3G10 and RedWideGamutRGB are a starting point that preserve ALL of the camera information. You need to apply a transform (3x3 matrix, LUT, etc...) to get it into a proper viewing / delivery space such as 709, 2020 and / or P3.

Tim, thank you for sharing.

Would you say this is CA?

bad CA from my 24mm rokinon. Someone on FB groups said my lens might have a problem because theirs is sharp but I think I am ditching these rokinons and moving on up!

What does that frame look like in RedWideGamutRGB? (RWG for short)

however here is a frame from redcine with RWG..

Tim, approaching wide open on this one? :biggrin:

Holy shit. In the still, I can see some "Grains" but in the motion picture, I barely see the noise. It's much cleaner than i expected.

its because its much smaller noise than dragon
 
Graeme was kind enough to let me test drive what he has been working on and now the video has been updated with a render using RWG/L3G10 + his special wizardry. The first go round was DC2/RG4

Sorry, got busy, then the holiday.
If you wouldn't mind sharing a frame around the 2:52 mark, I'd like to poke around 200-400% to see how the image holds up.
R3d would be great if that's ok. Much appreciated!

Thank,
 
Tim,

Thanks again for posting yet another great frame from your Epic-W Helium. Hopefully if the sell of some of my Land goes through, I'll be able to put a deposit down for an Epic-W in the next few months.

Wow just had a look at the new version and Graeme's new color science seems to be a huge improvement in these over-saturated highlights. This looks really nice. Thanks for the tests :)

Yes I just wish I had not posted it publicly so quickly using DC2RG4
