Seeing in RCX what the sensor is seeing

[Alexey Milokost]

Hi all,
When I view R3D files in RCX straight from the SSD reader, is it possible to view them in RAW not in Preview mode or any other viewing mode? Can I turn off the metadata anywhere and see a flat RAW in RCX?
When I was shooting on EPIC, the setting in EPIC was REDGamma. After watching it in RCX everything was as a Preview color. I switched it to RedlogFilm and it became more flat/more like RAW. So, I guess, my question is if RCX can view and export real RAW without any adjustments and tweaking?
Thanks!

Hi Alexey

The sensor is CMOS with Bayer Pattern, that's what the sensor see, you cant have bayer image. You'll always end up with debayer image as starting point.

I'm not sure by what you really mean by RAW. But looking at your question, i assume you are not referring to the bayer image but a linear light footage without any gamma or metadata adjustment.

You can do that by accessing RC-X Pro preferences, turn on the "Show Advanced Control", by doing so you can have access to the Linear option in Gamma Space section. You'll have your linear light footage. You also have to reset the metadata so everything is back to default.

Thanks for a reply!
I guess, I mean when you shoot, there is viewing option OFF, RAW, Exposure and some others. So, when I choose RAW during the shoots, I'm seeing how the sensor is seeing (am I correct here?)So, after importing to RCX, I want to see that same image! So how can it be done? By resetting Metadata, clicking on a little 'm'? Can it be done automatically during import? By the way, what the little 'd' stands for?
Thanks in advance!

The closest you will se as to what the sensor actually "Sees", is if you choose linear as gamma in RCX.
That is often and for many not of much use, though, as we don't see that way. If you learn to know how to look at a liear image, it can actually be quite informative, though. Like looking at log images can be very informative. You just have to get used to what to look for in those images, and they can have tons of usefull info.

Cheers!

What gets recorded isn't actually what the sensor saw.. its gone through redcode first at a minimum. Red like us to see it only after their secret dsp / debayering processes (which are pretty darn good). If it was pure raw, and losslessly recorded, we could probably shoot a few seconds with the lens cap on at the start of a shoot and then do blackshading in post. Maybe I'm wrong. But unbayered raw = NO

You are looking for linear image which has been answered above. the RAW in camera is the linear gamma 1.0 in RX-C Pro

Here is what he means I think... If you tap the color scope on the touch screen, in the bottom left side of the screen the window drops down and gives you an option to view the image in raw format. He wants to know, how to get the raw format type to be reproduced in RCX. I don't know either. But what I have done is adjust my color, contrast and lighting temp. to get pretty close to the "raw" image type.

One minor correction in this thread, looking at linear gamma on a srgb screen is not the same as looking at the actual linear image. The entire desktop gets an inverse 2.2 gamma curve applied to it before being displayed on the monitor since it assumes every pixel on the display was pre-gamma corrected to 2.2 gamma. When you bring up a 1.0 linear image on your display without a LUT you are actually seeing with your eyes an image which is in .4545 gamma. REDGamma/RG2 is actually closer to what the sensor "sees", just set the white balance to 5,000 and you'll be pretty close. Someone on the RCX team could probably give you the closest settings for tint and iso that apply the least possible color transforms.
