  • 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 :)

Wow!

First, thank you to everyone who is posting stills and shots from their cameras. I imagine this is a question for Graeme.

This is the blue channel at 1:1. Are these blocks due to wavelet compression or something else? Do they exist in camera RAW or are they introduced in Red Alert?

edit: Well, it got compressed when I uploaded it, but you can still make out the blocks I'm talking about or have a look at the original tiff.
 
Jim confirmed on another thread that RED LCDs were shipped out with the first batch. He ran out of them and instead is using a Pani on his RED camera on some Indy (race car) location shooting. I believe he is there now. IE Live...

Thank you so much for sharing all this, guys…this is priceless.

About the first picture of this thread, I think I would have made a different choice regarding exposition, I would have tried to keep as much informations outside and let my talents in darkness and then try to bring them back in post.
I do believe that overexposing half of your picture is not a solution that will be very popular.

Comes out pretty well here..

Blue channel is getting chewed up really badly by the wavelet compression in the HDR.tif shot as well. Please tell me we'll be able to scale back the compression in the future at the cost of higher datarates.
 
So Gavin, I guess that means we can finally say that green screen is better, huh? At least for CMOS stuff...

Edit: CMOS = 2 pixels green, 1 pixel red, 1 pixel blue... or am I misunderstanding?
 
I'm seeing some patterned noise in the overexposed part. This is only adjusting Levels in photoshop. 100% crop. Jpeg quality 10. From "in_outUP.tiff"

Just like DV :(
 
Film scans get ugly in the toe and shoulder too, depending on the stock. Of interest: often the blue channel is blurier on film stocks too.

JPEG Quality 10? Doesn't your's go up to 12? ;)

That "in_out" shot started just inside and exposed properly, I was shooting handheld and saw my cousin and her boyfriend doing some cute stuff so I just turned and shot, it's really a case of Wow that looks great and I didn't even try and adjust the exposure. Even still, I might have let the concrete blow out as long as the other stuff held. I would have no problem using that shot in a scene.

Odd that the blue channel seems to suffer more than the red. I wonder if this is a compromise in the compression with the data rate or if it has to do with the debayer / demosaic approach? I think this accounts for the cyan fringe we see in the bokeh, I'm willing to bet it's not so much an issue with the glass and we would probably see similar fringing on other lenses that produce similar bokeh. I guess now I'm really anxious to see results from Nikon and Canon glass as well as other PL mount cine lens options.

...I wonder what we'll get when using lenses that have more apparent chromatic aberration? Will blue/purple CA and fringe that is normally produced with certain lenses be amplified?
