EX-1 colour-matrix settings, a side note

UPDATED april 10: https://marvelsfilm.wordpress.com/2010/04/24/all-new-sony-ex1-picture-profile-for-cinematic-look/

Questions have been received about the way the picture profiles were defined in the first place. Most people get the impression that my EX1 PP was assembled by trial and error. This is not the case, although i must admit that some discussions on this weblog might give you that idea. The only setting that was ever experimented with (and eventually left alone altogether) is the PP’s black setting.

The colour matrix settings i use are copied directly from Bill Raven’s “second profile” with a slight lift of the reds in the PP’s “White” section.

I use Bill’s colour matrix settings because they are derrived by sheer measurements, using expensive testcharts and -apparatus.

If you don’t want to dig through this weblog, here are the colour-related settings in our PP:

Matrix ……………on
Select…………….hisat
Level………………0
Phase……………..-5
R-G……………….75
R-B……………….0
G-R……………….-18
G-B……………….-32
B-R……………….-27
B-G……………….13

Color Correction…………..off
White………………………..on  -> both settings +2

For the complete profile and related discussions see:  my Ex1 PP for filmic look article

Cheers!  Martin.

    Why would sony market a camera with “wrong color settings”?! Does this all imply that setting the EX1 to standard, signals are “off” on the test equipment?
    I.O.W. why not leave it alone and trust Sony’s development dept.?

    Sony offers just a few colour matrices. You have to agree with me, that some of these matrices are a bit weird…
    Yes, you could set the colour matrix setting to Off – no problem – but you will get very much a “video look” with little latitude to each chroma channel; so colours over-saturate and blow-out easily. Sony has come up with the Cinema colour matrix to reduce saturation and give the picture a 60’s “Fuji film” look.
    Bill Raven’s colour matrix is a well balanced colour setting, with above-normal saturation but with respect to the vectorscope measurements (correct vector positioning). It gives nice saturated colours with enough latitude per channel.

    I just tried your PP, looks pretty good so far. I will test it,
    Thanks in the meantime.

    Hello Bill.

    Nice to meet you. I’ve switched back to EX1/DOF adapter shooting and left the DSLR hype. We’ve just published a home-brewn profile, after using your settings for almost a year; for creating a different look.
    It is published onder https://marvelsfilm.wordpress.com/2010/04/24/all-new-sony-ex1-picture-profile-for-cinematic-look/ I’d appreciate if you’d comment on it if yoo find the time.
    I’ts a tad too red maybe, not sure entirely.

    Did you, btw, ever expect your article/settings to draw that much attention? Have you ever revised your settings?

    Thanks man!

    HI Martin,
    I loaded your settings into my cam and compared images to my settings. Yours definitely look less saturated, greens don’t look nearly as “neon” as mine. All in all, I think I prefer your settings, especially for better post CC. I’m going to experiment some, will get back to you if anything comes up.

    Indeed, I was quite surprised at the acceptance my settings garnered. After all, anyone with the right equipment could have done this. No, I haven’t developed any newer settings, spending my lab efforts on calibrations for other cams.

    Best regards

    That’s cool Bill. The philosophy behind using the Fluorescent matrix in combination with a color correction towards red, is to lose the weird green hue that the EX1 exmor chips produce. The FL Light matrix seems to add a little magenta/blue. This corresponds to my findings in FCP: taking a white balance results in magenta added to blacks to compensate for the green hue.

    If the profile is now too red, as one person suggested, i get a very nice result when i correct the whitebalance in the pictureprofile by shifting it one point towards blue; but that’s not very scientific. I am sure you can come up with an in-profile CC for that (may it appear necessary).

    Because i like fine detail (but hate halos) and use a DOF adapter, i wanted to use some form of detail enhancement. While busy experimenting with that in low light, i suddenly saw that switching from the FL Light matrix to the Standard matrix meant more noise – the FL Light matrix seems to render less noise in the picture with these specific settings than any of the other matrices.
    We live and learn….

    Cheers,

    Martin

    I loaded up your pp on my ex1r and went out for the day just shooting stuff, airplanes, boats, weeds, people, animals, flowers and buildings. I can honestly say it is probably the best i have used so far. It looks awesome on a 52 inch high def. my friends were blown away with how real the results looked. A sincer thanks for your work on this pp it’s by far my favorite.

    Vern, thanks for your kind words. Did you use the PP version with the FL-Light matrix or the Standard colour matrix?

    Martin.

    Just a little addition to my last comment. a friend and i both have the ex1 and he put an allester chapman profile in his and i left yours in mine and we went out and shot the same footage with each camera at the same time and at the same angle. then we put the two vid’s up on the tube with no edit. they are both very good profiles but we both thought that in edit your profile would need less work in color correction on out of doors immages. for indoors images i guess it’s what you prefer. i expect i will stay with your profile because generally people seem to like it better and we aim to please. again thanks for your work.

    Hi Vern.

    Thanks for your kind words. We have altered Chapman’s profile on a few points after shooting a short movie in 2009, so that it indeed required less color grading of the skin tones.
    There is always the matter of personal taste and Chapman’s profile is probably calorimetric more precise, but when it comes to skin colors i think i like ours better.

    Cheers!

    Martin
