His "cloud" is more like "ground"

If either can pull this file I'd appreciate it. https://cloud.gerade.org/index.php/apps/files/download/public/Axiom/alpha/IT8-Daylight-Shadow-2014-23-02_14-45-35.raw16.xz

troy_s: it seems that not just apertus.org is affected from the server issues we are encountering but also sebastians own cloud
03:17
Bertl
hopefully services will be restored during the day
03:41
troy_s
Let's hope so Bertl
03:41
troy_s
I promised Se6 that I'd have the matrix done.
03:42
troy_s
But it won't be happening. :(

good morning
08:19
Bertl
is it good? :)
08:20
se6astian
could be better, could be worse
08:20
Bertl
looks like a little better would be good
08:20

Hey Se6astian, is the apertus website offline?
08:48
Bertl
yup
08:49
se6astian
it is
08:50
SashaC
Thanks Bertl and Se6astian? Any idea how long this might last for? BTW, how are you guys feeling after Berlin?
08:51
se6astian
I ll work on restoring it on another host after my c5d appointment
08:51
se6astian
Berlin was great, we should write an article about it soon :)
08:52
SashaC
Yeah, it's such an amazing place to be! Can't wait to hear more about it :)

16:25

I just tried, works fine
16:25

Would you like a screenshot?
16:26
troy_s
se6astian: I get the "ownCloud" logon.
16:26
troy_s
On the image.
16:27
se6astian
I found the problem
16:27
se6astian
pmed you
16:32

se6astian: Works. Guess as to the color temp of the sky?

troy_s
se6astian: And if you look at the profchek
17:13
troy_s
se6astian: You can see that they are pretty dismal on the DE2k side (13)
17:14
troy_s
se6astian: But the worst offenders are the darker swatches
17:14
troy_s
G03 for example
17:14
troy_s
F03 is perhaps the words
17:14
troy_s
worst
17:15
troy_s
And I see RGB values of 17.66, 17.378, 12.659
17:16
troy_s
So... exposure.
17:16
troy_s
Not clipped now, but too dark is my first guess.
17:16
troy_s
se6astian: So some points... a little brighter (Quarter to third of a stop)
17:16
troy_s
se6astian: Avoid the flare (very bad here, which is also likely completely skewing the results)
17:17
jucar
joined the channel
17:17
troy_s
(The flare off of the bright white curtains is probably grabbing glass badly)
17:17
se6astian
noted
17:18
troy_s
se6astian: That's about all I can offer at this point.
17:18
troy_s
se6astian: We need a way to figure out what the native exposure is so that you aren't blindly shooting.
17:18
troy_s
se6astian: The guessing is killing us.
17:19
troy_s
se6astian: If you take a light reading with an ambient (or a spot if you have one and a grey card) we could likely calculate it closely enough to give you a much better target.
17:19
troy_s
So I guess the results of this experiment are "Qutie a bit better, but still unacceptable."
17:20
Bertl
what is 'native' exposure?
17:24
troy_s
Bertl: Any idea as to where the native gain is on the sensor?
17:25
troy_s
Bertl: (If we know where the sweet spot is on the sensor, we can try to estimate an ISO. Most sensors just offset the latitude up and down when undergained or overgained, as opposed to adjusting a more traditional ISO sense.)
17:26
troy_s
Bertl: Is there some control over the channels? Even with that likely 6000k shot (or so?) the blue channel seems _very_ low.
17:27
troy_s
77.857 77.719 54.126
17:27
troy_s
That's an achromatic swatch.
17:27
troy_s
Seems that the sensor is pretty heavily biased toward red.
17:29
troy_s
Egads. "(Rating: 6): Zoom for focusing"
17:29
troy_s
Uh... No.
17:29
troy_s
Bertl: That reminds me... on the subject of framelines and overscan marks etc...
17:30
troy_s
Bertl: It would be great if there were a buffer for say, three still images with associated alpha (like a TIFF)
17:30
troy_s
Bertl: Such that you could cache mask settings. That would allow you to toggle between a couple to three differents for different needs. Variable opacity.
17:31
troy_s
(and it indeed solves all of the issues regarding custom frame lines etc. Just generate an associated alpha TIFF of what you need and away you go.)
17:31
troy_s
(Solves everything from simple frame line needs (standard mattes) to offset frame line needs (standard mattes offset to upper third (often used when the shooter _knows_ they are delivering to different formats to solve compositional problems)) etc.
17:32
Bertl
okay, slow down, I have no idea what you're talking about :)
17:32
Bertl
a buffer where? what do you want to buffer?
17:33
Bertl
where does the alpha come from?
17:33
Bertl
and is that regarding 'feature list' or more related to the matrix calibration?
17:38
troy_s
Bertl: Sorry was reading list and forgot about something I was going to chat about.
17:38
troy_s
Bertl: On the subject of frame lines and mattes for shooting:
17:39
Bertl
so this is basically a feature idea/request then yes?
17:39
troy_s
Bertl: When chatting with a playback fellow, we were discussing a newer vendor's display and he was wondering how to deal with framelines and such as he wanted a method to show the director the framelines. The problem is that he needed to show two variants.
17:39
troy_s
Bertl: Not really a request... sort of mandatory. You need to know what you are shooting.
17:39
Bertl
okay, so please put it together in an email to the list then
17:39
troy_s
Bertl: I don't like that list.
17:40
Bertl
how so?
17:40
troy_s
Bertl: Just not into lists. Random noise.
17:40
Bertl
well, otherwise the chance is good that the information gets lost somewhere
17:40
troy_s
(Probably the crusty bugger that has been around dismal design in free / libre software for about 15 years.)
17:41
Bertl
the only alternative I can think of right now is that you can add it to the wiki
17:41
troy_s
I will stuff it into the philippej document.
17:41
Bertl
i.e. create a feature collection on the wiki and add the features there
17:42
troy_s
Bertl: Link me?
17:43

https://wiki.apertus.org/index.php?title=Main_Page
17:43
Bertl
but give it an hour, we are currently moving the site
18:04

Bertl / se6astian: Bumped main page to begin to include onboard hardware / software interface discussions.
19:03

https://wiki.apertus.org/index.php?title=Main_Page
19:03
troy_s
Added immediate thoughts, order obviously still subject to change.
19:04
troy_s
The default view is that top list of higher priority things that assists or shooters would probalby require at-a-glance
19:04
troy_s
rexbron_: Have a peek and see if anything pops into mind.
19:05
Bertl
can we do white balance/color correct? is it possible? :)
19:13
troy_s
LOL
19:13
troy_s
Bertl: I have high hopes if we can actually deduce the EI / ISO of the sensor at the native gain.
19:13
troy_s
Bertl: Right now it's a lot like playing lawn darts in the dark on Mars.
19:13
troy_s
Bertl: Where we only get to actually figure out the score once every year for about a month.
19:14
troy_s
Bertl: Refreshed it. Also included some of the discussion on file format breakdown for filenames.
19:14
troy_s
Bertl: Obviously it is subject to how to dump to the filesystem, but I suspect that you were leaning toward a single blob with the raw frames inside, and the format listed is in line with that.
19:16
Bertl
okay
19:20

On Focus: No. No. No.
21:16
troy_s
Focus is the person who is focusing the damn camera, and unless the design has shifted to a fscking newsie camera, it is a moot point. Offer the SDI out and let the peaking and magnification to the display of the focus puller.
