  • 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 :)

RED 8K Sensor Test 2017

Dam dude do you ever sleep.. This is just what I was looking for to give me some confidence about where I will go with my RED in the future.
Thank you +1000 Phil.
I don't know how you do all this and keep working and then find time on the road to do more.

Im not worthy....
 
Phil - So when reading the DR chart, do you start from the 0 patch at the clip point, or do you take it from the second square? Thanks again.

Heh. Thanks man. I like to think I'm very "Doctor Strange-ish" and do the whole aural sleep thing.

It says on each chart if the first patch is clipping or not. If I've marked the patch as 0, that's full clip. If it's 1, that's an exposed stop.

The other bit there is if the chart is at full clip there is the weird minutia in there where each channel eventually clips, which is different depending on the light source and OLPF.

When clipping the chart would be a full RGB channel clip. So in practical use there's even more in there if you aren't looking to "hold" that highlight fully.
 
Thank You Phil...........You always rocking..............

Phil how come Helium sensor comes out way sharper than VV? itsnt that bigger sensor is more detail? Maybe you can add sharpness test in soon ?

The lens is stopped down to make up the exposure differences between ISO 400, 800, and 1600. Which is significant.
 
Awesome info, Phil.

:)
 
Thank you Phil, you're amazing!

If I'm filming with Helium 8K & Dragon 6K, what changes do we have to do in color grading to make them match?
I wish if we had a LUT for Dragon, so it's easy to match to Ipp2 Helium, or the opposite. (would be good for 2 camera shoots Helium & Dragon).
 
Thanks Phil, this is such a super helpful comparison test. Is there anyway you can post the last segment--the skintone tests--just as LOG 3G10/RWG? I just want to see how they'd look with a manual correction.
 
Great work Phil, hats off...
 
Thanks again for the meticulous research and clearly presented findings Phil.

I thought the ISO Rating Range and Personal ISO Rating Advice table in particular was a nice concise way of explaining where things are at in regards to ISO/OLPF/exposure combinations.

Looking forward to seeing more Helium and VV output from yourself and others.
 
Hey Phil, any thoughts on why the shadows have such a hard green shift on the Helium? It's very clear in the ISO test. The black areas of the color checker are super green in the Helium footage.
 
Very impressed by the dynamic range of the VV sensor, I did not expect it to surpass Helium but I guess the larger pixels help.

This really shows the difference between OLPFs and skin tones. The aptly named skin tone OLPF is much better, the LLO and STD skew too much toward orange/magenta.
