  • 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 :)

ISO 500-4000 comparison...

Not sure why it isn't marked on ISO 4000. That was shot with gain... I'm sure of it. Everything shot today had gain.

Wait, I'm confused. I thought the higher ISO was gain.
Could someone explain to me?

Come now Jim, be fair :-)

If you like what you get, you ask for more. This is life fundamentals 101.

If I have a great time one night and approach my wife the next night, I doubt she would sigh "never enough..."

Now if you posted these pictures and the board responded with...crickets...then that'd be sad!

:-)

Lesson 1 : So why did you decide to use gain if the lighting was sufficient to lock down @ 0dB with the ISO500 shot that is?

Cheers,

Right now, gain up takes an upload. So we just shot everything with gain today. Tomorrow we shoot normal.

Hey Now... all this new information is great for all of us on many levels. But I would like to say that it is also great to see you excited on a level that is nearing NAB eve. This also inspires us to ask you for just a little more... Jim, you and your Team have created more than one monster here...

I gotta say, it's great to analyze the images, look at all of the stats, compare this to that... truely amazing in it's own right, but I've also been getting excited by all of the creative doors that are opening.

The RED ONE may be able to shoot at midnight by pure starlight, but I'm sure there will be images it is capable of capturing in completely new ways we haven't even thought of yet. I've always been an advocate for improvisation and the idea of creating new looks for shots while on set... now THAT is really exciting to me as a Director.
 
dead pixels?

dead pixels?

No panik please. I am more than impressed by this camera and sensor. But I just pushed that chart image and in the 4000 ISO one there is a horizontal line, some "dead pixels". This is not realy a problem for me, just don't think not telling is any good either.

You can see that line without pushing. I wondered the same.
What is it?
 
These tests are awesome, thank you Jim, seems that RED has a 24 hours party, playing arround. If these sensor has arround 300 ASA without pushing, then we really need a lot of ND Filters. Hope there will be a possibility to have a knob for -gain so that we might go down to 50 ASA.

The "dead pixels" don't realy concern me - god, at 4000Iso - any HDCam I've ever used usualy showed up with dead pixels in low light at 9db. Only the horizontal line could be an issue. I had a HDCam 750 show up with a "net" over the entire image in a low light 9db gain situation - nearly useless.

Hi Daniel,

I have a feeling that wont work, as the s/n ratio would be rather high. 'Expose to the left' is not a good idea IMHO.

I used to have a ND 3.0 (10 stops) filter for timelapse, It could come in useful!

Hi Stephen
I know you're right, but I hate to have to many filters in front of a 35 (dark image and danger of lens mirroring). At least we don't have a mechanical shutter and I hope the EVF will be then clear enough (easier to pull focus).

Hi Daniel,

Some Cooke Zooms have a slot for a gelatine filter between the elements, that eliminates the 'mirroring' issue, Would be good if Red lenses did this too.

If that line is a "resident defect" or byproduct of the CMOS in each camera then everything upwards iso 2000 is quite useless. (at least to me)

Unless you're willing to do post work:construction:
I think any shot higher than 2000 ISO is a "last resort" thing to do anyway, and will require post work anyway to get a nice image - so then need for fixing a pixel or two, or such a line-thing isn't going to happen in everyday normal shooting conditions - I want my RED!!!!
 
I see it the same way as my other swiss brothers. Please try to put some realy low Iso funktions in it. Kinda like in the Canon 1DS Mk2. It goes down to 50 ASA and that's very good to work with.

The best thing would be somme ND Filter built in to the cam, like in normel ENG Cams. So we don't have to carry a box around and clean the filters every time we want to put them on the mattebox. This will slow us down in a big way when you do some ENG work.

I know it's a "filmstyle" camera. But that would be super handy. Maybe in red two?

So keep on rocking. You guys make my kay.

As was warned in the other threads... NDs should be a part of everybody's kit [regardless of the camera].

Hi Brook,

Whilst that's true, historically digital (video) cameras have had build in ND filters of 2, 4 & 6 stops. I am sure companies such as P+S technic will be able to add the option if it's not available from the factory.
