I will try that workflow, though i dont see why its different than adjusting white balance in RCX with the dropper. Or you could look at the RGB waveforms and make them even.
Hi
There are many approaches to this, and they can all work if you know what you do.
Look at Michael Cionis examples.
Basically it is the
"WB and go for it" approach - which works really well!
The second is more like:
"preserve all data and do not introduce extra noise or risk channelclipping (especially in the red channel under tungsten) in the development of the files"
Which would translate into something like developing at cameranative settings into EXRs or 16-bit DPXs for CC and VFX.
I have come to take a rather practical approach to this.
1st - depending on production and budget...
I teach a lot of photographers and post people to use the R1/Epic a lot like a video-cam on steroids these days, with quick turnaraounds and excellent results.
You get 90% of the potential for 10% of the effort...
Simple. Quick turnaround. Great results.
Enjoy the extreme latitude (not DR) of the cam, as to how wide in the exposure of essential stuff like skintones, actually work very well.
Expose so that it looks good. Then it probably is...
Then there are the productions that really want to push it, where I work with the DP and post people to recognize and familiarize themself with the sensor and its quirks and treat it like a filmstock.
Most of these productions have ended up shooting the camera "flat" allmost totally independent of light conditions, and the post process have taken off from there. With really amazing results.
This is a more knowledge/testing/time/workflow-heavy approach, but the results can be really surprisingly stunning.
Being a pragmatic, I often use elements from both approaches, when I am personally in charge of the productions. Not all shots gain from the "take no hostages" approach. Only those that are either dynamically or noisewise challenged. If there is enough light for the exposure, and there is nothing challenging the image in the top, why not play it simple.
I rarely (but as allways, the significant word here is "rarely" not "never") set WB bellow 4400 or above 6400 kelvin, as I see that beyond those points noise is introduced/accentuated differently/more significantly, and channels risk getting too squeezed in the top for my liking for further grade.
OTOH
If it works well. I like it. You can finnish many projects off just in RCX, if all you need is primarygrading, and the conformtools in RCX have matured immensly in a very short while. It does surprise me a bit that the Adobe guys haven't used this approach a lot, while waiting for "proper color tools" in PP.
Simply put. There are many approaches and considerations, and there is not one religiously "best" way to approach color and DR on the RED cameras.
But simplicity offered is a good thing to get through, as the voodoo-tricks often are based on hearsay, lack of knowledge and give funny results.
As to this test, I like it, but I havge some comments...
As I have run a bit of tests on the F3 and the RED cams as well...
1st off, the F3 became a camera and not a toy with the LOG option.
Good!
Still the exposure latitude for the Epic/Scarlet is incredible. You can expose all the way untill clipping, without killing off tonality and messing up channels. I have seen this on no other camera so far. How low you can expose skin, is more a matter of taste... Clipping is a very true and hard reference... But to my taste, the lower exposure of skintones on the Epic by far "overniced" the F3.
The F3's two upper stops before clip, did not look very nice to me, and was not a place we felt like putting critical "good looking" information.
As long as you don't really challenge the sensor/technology, and expose a bit fat and narrow, the cameras probably will be able to give you very good and similar results.
And that's the good thing these days. Finally videocameras are becomming basically "ok and useable", rather than "ouch, thread carefully or the image will break" able tools to use.
Me likes.
But simply put:
The variables are many and often uncontrollable.
Find what works well for you with a given camera
Stick to that
