  • 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 :)

2000-3200 ISO full res Helium Tiffs

No one get mad at me...

but the overall color impression is better in the top one.

can we achieve that in the bottom one by going Log3G10 and RWGRGB and transforming on the bottom one?

Better.
In the upper one as well.

people should really do tests with high lights , why all these low light tests? these are cinema cameras not really worried about low light prob never use above 1600 ISO if that

So low light capabilities of a cinema camera should be an afterthought? Lowlight should be just as important as highlight retention and every other criterion on which cameras are judged.
I for one LOVE the fact that Red finally decided to tackle the lowlight issue.

That's simple color correction. Highlights in the Hélium looks more natural and better color rendition than the Alev sensor.

Based on what ?
Drastically boosted ISO examples ?
 
It's an interesting conversation regarding ISO and low light filming.

In the film world many who have made the transition to digital have reaped the benefits of having a much more sensitive to light medium which has equated to less of a need for much more lighting on set. This is something that can be seen on the studio level as well as how it's influenced independent productions. I see entire films shot with just 1-3 lights these days (for better or worse).

Helium is indeed better at higher ISO ratings. Cleaner that is. And that's something a certain portion of shooters have been absolutely begging for. Others may not have been in such a bind with low light. There's just different types of people, shoots, and shooting methods out there.

I think you'll see a lot of Dragon and Helium productions moving forward and not as clear as a shift as moving from Mysterium-X to Dragon for instance, but that's just my opinion.

Helium will indeed have certain advantages, such as low light capabilities, but this to me is more about choosing a "digital film stock" for what you'd like capture.

RED has "done the thing". S35, VV, and whatever lays beyond the future horizon. They've gone against the grain (oooh pun) here in many ways by offering multiple sensor technologies, multiple formats, and host of other things and from my perspective mostly to give shooters choices as to which is best for their needs.
 
more than comparing alev vs helium. Im more really concerned with what images from the Helium looks like. Comparing is great of course too but at the end of the day does it look good? Yes. Also guys check out Cameron's linked tiffs. Those to me are more realistic examples of how the camera would probably be used.
It doesnt compare sensors but it does tell you that the helium looks good.
 
Yeah, Alexa looks like film in this shot with color and tonality and the Helium, while cleaner is more artificial looking.

I'll wait until the Helium sensor is out of Beta, but it's not always about "low light performance".

Skin tones and highlight retention and rolloff are traits that the Alexa excels in and Dragon in it's Weapon body are VERY close to. Resolution wise, it's no contest between Arri and Red.

Resolution wise Weapon CF is 20 years ahead of ARRI :) it is not even fair comparison lol.

Some basic slider adjustments in Photoshop. More blue and less green in the midtowns and shadows.

Oh those silky blacks.

Here is another one, helium 12800ISO vs alexa raw 3200ISO (max alexa raw iso, and then exposure + to reach the same level as helium picture.... Alexa falls flat on the floor in comparison, no joke. klick to see larger frame.

We are doing a UHD side by side comparison now, this is just a frame grab from that. But it´s quite easy to see who has the upper hand.

The Helium grab doesn't look like it's graded properly.
 
Wow! Truly night and day! I'd actually like to see a 4K low light comparison with the Sony A7S if it hasn't been done already. Practically speaking, I'm not sure 8K will be all that beneficial for regular lighting and daylight situations, albeit it will be gorgeous, but for technical and resolution strained things like ISO performance, the added resolution benefits of 8K are obvious as evident in this test. I'm surprised the color grading was even mentioned here as I'm sure it was just a quick test and color wasn't even a factor.
 
So guys, Do you think now Hellium is better then Alexa?
Because on the film sets very often (in the most cases) DP says that of course Alexe is better then Red) and the main reason of it is Dynamic range (+2-3 stops in the highlight and 2-3 stops , more clean in the shadows)

So Alexa has 4 to 6 stops more DR than Dragon? Or while mentioning Red they speak of Red One-m?
