seems those tests you posted were deliberately twisted to trick people. I chose all the contrasty shots as digital yet they turned out all to be film, i.e. seems film was deliberately made to be more contrasty and blacks crushed etc whereas we all know that's really more the look of digital or at least Red specifically with its lower dynamic range
The upper one is Epic and the lower one Alexa. Both produce great results. The pillar in the BG looks different because the shot was taken slightly later in the day and the sun had come around.
Because this isn't an Epic vs Alexa thread.
This is an "examples of natural filmic color" thread... and I have so far seen only one actual example of a guy making RED footage in the style that I like so far - Gunleik!
And it's not some wacky style that I want... just the skin tones of awesome movies
Gotta find some more examples of RED-shot stuff before shutting up
Also, why should RED be happy with only beating Alexa? The goal is to beat film in every way - and that includes capturing the color data needed to make any filmic look that we want from the raw file IMHO!

... there is a real difference in the USERS of Alexa versus those of Red cameras. Alexa users are by and large more traditionally minded shooters with more of a "classic film" aesthetic. Red users tend to be newer to the industry and more "edgy" and more willing to try new things ... for whatever reason. This includes the mindset that makes one invest in a new camera system from an untried company.
Could it simply be that you are seeing the different choices made by these two groups of users?
Actually, that doesn't really surprise me. The primary differences between the two that I've generally seen (or more accurately "felt") as a colorist have been that the Epic seems to produce a somewhat "crunchier" (i.e., a bit more black compression) and "harder" (i.e., "sharper," but not always in a specifically definable way) image. The Alexa is a bit "softer contrast" (i.e., less black compression) and "softer image" (i.e., less sharp, but once again not in a specifically definable way). Skin tones are, to some degree, a result of that, specifically the black compression, because shadows on faces often define "modeling", and when they take on a color cast - usually red - it becomes very noticeable, particularly when color grading, which is essentially a linear process, cannot cleanly control it. The only thing I find a bit surprising is the magenta cast in the highlights on the Alexa image, something I usually don't encounter (I usually see more of that with Red images, actually).
I think this all indicates that concentrating on any one specific characteristic of an image as indicative of a camera's capabilities is to not be very realistic, as all of the visual characteristics taken together are what contitutes a camera's "look" and "signature." And it also indicates that no matter what a topic starts as on RedUser, it inevitably turns into a contest between Red and anything else, which to me remains a bit of a tiresome exercise. Once in a while, it's nice just to talk about things in general rather than turning it into a contest.
I wonder if 16bit Epic material will give us more of the subtle shades Bruce seeks?
Mike, LogC on the Alexa is gamma < 0.6, so that'd lower the contrast before grading. If that's something you like, you can always do that with the linearity of the Epic data too. As for the blacks, the low contrast filter on the Alexa will reduce image contrast still further pumping extra photons into the shadow areas.
Good comment on "contest" Mike - I prefer to talk about why things look the way that they look - then people can learn from that to use the available tools to make the images they want look the way they need them to. The whole idea with the RED cameras is to be neutral to the image making process. From reading this thread I can see that is not always what is wanted, and I can take that as good feedback too. There's always going to be improvements in how we develop the raw conversion process and threads like this serve to feed the math that I get into in positive ways.

Here is an example of some 80's inspired saturated skin of various shades. This is not so much a comparison and an Alexa/Epic thing, this was shot as an A/B cam setup on a shoot I did recently. It was graded on set by my DIT Stephen Latty on a Resolve to MATCH. Can you guess which is which? Why? What are the visual cues?
Alexa was shot 60fps Prores422 and Epic 120fps 4KHD.
Download them and watch them in a proper viewer (like Photoshop) as they appear a bit desaturated in Firefox and Safari...

Both of these looks very good. The Epic is so much better at skin than RED One MX.
I'd say the Epic is still going slightly gray in the highlights (see the knee of the girl with the blue top in the upper image), but not enough to be objectionable. The Alexa appears to be going slightly gray in the bottom shot on the guy's leg. Overall, a toss up between the two, and given the superior resolution and framerates on the Epic, I'd pronounce it the winner here.
Graeme, please keep tweaking the color science! Neutral is a great goal, but 'beautiful' isn't bad either, and it's probably closer to what most of us are actually shooting for.![]()
Thanks Rivai - I do take threads like this positively and I do try to separate hype from fact. That's why I like blind testing where people don't know what they're looking at, although it's not always the easiest to arrange. We all keep learning at RED, myself included and our goals are obvious - the best image at the best price in the best form-factor. We'll keep working in that direction and keep taking feedback in the most positive ways that we can.

I also think that the film samples don't look like film. Perhaps someone shot the film tests underexposed.
When I shoot film negative I always try to overexpose it a bit, or a lot.
