ISO, ISO...

Hey Pawel, have you ever considered "frame averaging" or "frame compounding" on motion picture footage to achieve super clean, noise free images for stills? This is much more powerful than long exposures because it removes any temporal sensor noise or temporal compression noise. (You'll need a compositing system like flame, shake or after effects.)

Hey now that I think of it, frame compounding would be a kick ass tool to offer in Redcine-X for super clean, full resolution stills use.

I used to do some crazy timelapse boxes about 10 years ago and I'm super
excited about what we'll be able to do in the new cameras.

Now I'm drooling wildly at the possibilities that Epic is going to give us. As long as you guys have a 15-20 second exposure setting in that new timelapse mode I will be really happy.

that's a very good idea.

i've used frame averaging a lot just by taking multiple stills (works for scenes with extremely little or no motion). it's been around for awhile. this is what the sweet space telescopes like the hubble use. seriously reduces noise. highly recommended.

*for stills output you don't need flame or shake or anything. you can do it in photoshop pretty easily with layers (but each layer opacity for each layer needs to be equally balanced)

for example, layer opacity should be (starting at the bottom) 1/1, 1/2, 1/3, 1/4... (100%, 50%, 33.33%, 25%...) and on it goes 1/(n+1) where n = previous layer

So with a bit of light in the shadows and noise reduction we'll have ISO4000 for 2k projection?!?!!

Could we PLHEASE see some motion???? PLS!!

No, screw it!! Just start upgrading! Please!

Congratulations Jim!

Very impressive!

Is this the new sensor in your Red One camera?

I'm available to beta test that new sensor in my Red One if you need another opinion!

OMG, Wow. T2.8 Candle light.

I'm pretty sure Jim's shooting at 1/48sec.

I hope it was a 1/24 or 1/48sec Exposure.

Thanks

Shi... now I get this "I want the new toy!" feeling :)

David Mullen asked for tungsten... since I don't have a tungsten light here, I grabbed a candle. It white balances out to under 2000K, less than tungsten. I turned off all the lights in the garage and lit the candle. Best I can tell is this is ISO 4000.

The boys are going to yell at me again for posting this because they still aren't done. It won't be the last time...

Hi Jim,

Any idea where the 'purple' flame comes from?

Best

Fearless. Don't you have 'purple' flame jokes in the UK?

No Idea, it's 15 years since I lived in the UK, I don't remember any so if there were any they weren't that funny.
