I've been waiting to see Natural History subjects. Do have any longer glass for close work. Would love to see some very close macro work. Like full frame on the lizards head etc.
Thanks for posting. What do you have for Zebra option percentages to protect highlights?
Cheers,
Mark.

I used false color metering on the RED-LCD for these. I know they could be better, but great fun in the garden today in any case.
There are two Zebras, measured in IRE. Zebra 1 (highlight) indicator range defaults to 94 to 108. Zebra 2 (shadow) range is 0 to 8, or 44 to 47 when used as 18% grey indicator. In reality these can be put wherever you want. Just call up SMPTE bars or Luma Ramp to set them up.
False Color writes a preset range of colors over a monochrome version of the image. Image below shows how the colors fall relative to stops and IRE.

Stuart, nice images giving a good idea of the potential of the camera. Appreciate the natural tone of colors as well as your effort in controlling the highlights so well.

Nice test shots Stuart, and accompanying information as well. Caused me to wonder if Marty Stouffer is a reservation holder?

Thanks Stuart! I've been wanting to see some indication of how the false color works. Finally! Any chance of seeing it supered on the image?

see page 25 and 26. Also unless they changed it, Stuart's false color scale is different fromt he accuscene one (entirely possible).

I also did a quick version in photoshop (assuming that Stuart's numbers/colors are right.)

seeing as I've never actually seen RED's implementation I can't say for certain if that's an accurate representation. Also... that image is of a graded image so that you can see the full range. With red's 11+ stops of lattitude I'm sure you'd see far more data falling into the blue/gray/green range on a linear raw image.

But would you be seeing 11 stops in the EVF or LCD?

I would assume the false color display is a false color of the full 11+ stops before any LUT is applied to make the image look pretty.
Otherwise the false-color would lose its efficacy in my opinion.

Sorry Gavin,
I meant. Can the EVF or LCD display that full 11 stop range?

I don't think it can, which is why the false colors are necessary? I mean, if we could see all 11 stops we would know exactly what was being dropped off and what was clipping without the colors, no?

I'm just not sure. Is there a great thread on this or a sticky or a link?

I would be 100% confident in saying you view the linear output from the sensor without an LUT (aka the full 11+stops). The false color just helps you see what is really black and what is really white.

Thats pretty close. The EVF and LCD are viewing false colors generated in 10 bit REC709 color space. The red in that example says back off the exposure a bit.
Here's a view of an unretouched image capture and the corresponding false color LCD view.

Thanks for sharing, Stuart. Looks great. BTW, what's the vertical 1234 on the bottom of the LCD image, to the right of the power source indicator?
Stuart English
09-17-2007, 07:11 PM
Thats a placeholder for the audio channel metering Jeff

In cinematography (like in photography) everything is about a light.
To achieve the best results is about to shoot in certain parts of a day.
The problem with daylight is the color temperature of light..
The natural and neutral lighting conditions are the most accurate to shoot.
The main goal in CC is to achieve that accurate temperature of the picture.
If you have over or under light exposure then is not so much help in post.
Also we have to see how is to work in REDCINE to do 1st light correction or how 4K REDCODE RAW behaving.

Stuart you are an amazing man. I really love your work. I will be down at the red offices on the 25th, I have a meeting with Jarred and your designer to discuss my wheelchair mounting system. I would love to meet you and get your input as well. Great images!

Then why CC something to look like this? If I had to watch a whole film with that amount of saturation my head might explode.
Unless you were just trying to show how the picture holds up...but ouch.

Stuart -- this chart is extremely helpful, and the images are fantastic. Not sure what I'll get what I kick over the rocks in Central Park.
I think I may have missed it, are you referencing the colors off the EVF or LCD?

Just to show the saturation edge.
