2000-3200 ISO full res Helium Tiffs

[Brody_B]

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.

Did you use a longer lens on the Helium?

Am I the only one who's seeing a lens flare on Alexa but not on Helium? On Alexa I'm seeing an overexposed image with flared out/lifted blacks. Of coarse, flared out image will look different from non flared one. Also, I'm seeing a big depth of field difference. Different lenses or a different FOV with Helium camera being further away from the subject? Is that a fair comparison?

If we talk about Helium. But Dragon has the same DR as Alexa too I think.
We see Helium is more clean in the shadows and fast clipping highligts can be win by Nd filters, so we can shoot outdoors with ND ans with clean shadows in the indoors, more clean then Alexa.

Gorgeous images Cameron.

Can I ask what iso settings you used? And lenses?

2000-3200 MAINLY 3200
all were shot on a leica-r Summicron 35mm F2 (though i never opened it up fully)

THANKS!

I agree with Jake. It's a different setup. Lens and aperture appear to be different.
Though we can definitly say, Helium is a lot cleaner and have more resolution which was the point of the comparison.
On DR, it's not fair to the Alexa because of the flare, so lets not call it a test.

And is it a finger trying to remove the actual flare on the left, on Alexa's grab :emote_popcorn:?

And the person position. Which is further from the light source and closer to the truck.

 

[Owen Rennie]

Yep, not a good test at all. Looking forward to seeing something legit!

To be fair, Bjorn is out on a project and he just wanted to show a quick comparison of few picture aspects with what he had at hand.

Though it is a tendency to jump to conclusions when seeing tests online without a context so clarifying things like these helps in avoiding misconceptions.

So clearly this is just a low light sensitivity test, not a DR test since alexa is known to have 2+ stops of extra highlight DR over Helium. One should note that in this test Helium needs to be 2 stops better than Alexa in the shadows to begin to compete with Alexa. If it can, though, it might be worth noting that Helium with a motion mount might have a pretty similar sensitivity and DR to alexa but be 8k, have a global shutter and internal ND.

 

[Bérenger Brillante]

alexa is known to have 2+ stops of extra highlight DR over Helium.

Is it ? Compared to Dragon in DSMC1, Alexa does have 1/2 more stops, but to Dragon in DSMC2, it is the same, and furthermore with Helium, where did you see that ?

Anyway, I'm amazed at that 12800 iso shot's cleanliness.

 

[Jake Wilganowski]

thats pretty F-ing impressive

 

[Jake Wilganowski]

obviously if Helium is this clean you can expose lower to get your highlight retention and then lift up the lower end, So it seems like this will be a winner, Im going to test next week against my Magnesium, Thats the only way to really know, looking at other peoples stuff is always problematic

I'm very interested in seeing comparisons with your Magnesium, and not strictly as a comparison. Will mixing Dragon and Helium be a simple process? I'm anxious to see your findings.
