morning folks!

anyone wants to discuss the crowdfunding video for Beta ?
14:31
se6astian
not a lot going on here :)
14:32
se6astian
lets just prepare everything for the "voice of the community" thing
14:32
se6astian
firefox once did something like that
14:32
philippej
yep
14:32
philippej
For me apertus° is [...]
14:32
Bertl
what do you expect, no real discussion for a few weeks now ...
14:32
philippej
kind of thing
14:33

14:33
philippej
it will return (the conversation) eu grant took all the blood
14:34
philippej
interesting
14:37
Bertl
IMHO for beta we should focus on the fact that folks (mostly developers) can run their software on axiom and extend the hardware with their own designs, etc
14:37
philippej
extendability, openess
14:37
philippej
?
14:38
Bertl
of course, it doesn't hurt to emphasize that it will also be suitable as device itself
14:38
Bertl
i.e. you do not need to hack on it, you can just use the hacks of others ....
14:39
philippej
how can we show this, instead of just saying it ?
14:39
philippej
is it visual enough the upload of the firmware, or some code or ?
14:40
Bertl
maybe the april fools joke is a good way to show that?
14:40
philippej
looks at arduino website : Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments.
14:40
Bertl
i.e. build a controller and plug it into the camera
14:41
Bertl
write some FPGA and ARM code, run it on the camera
14:43
philippej
right
14:51
se6astian
good news: the alpha colors are calibrated now to a state where I can say, good enough for now :)
14:52
Bertl
excellent!
14:54
se6astian
I also tried subtracting an averaged dark frame
14:54
se6astian
but the truth is that in most shots the FPN is so difficult to see at all that I also have trouble to see if it gets better with the subtraction or not ;)
14:55
Bertl
btw, I remember that the green mineral water bottle was really nice ...
14:56
Bertl
with a little condensed water on the outside and the bubbles on the inside, and focus change between both
14:56
Bertl
(looked very nice)
14:57
se6astian
in prague, yes
14:57
se6astian
good idea
15:18
philippej
great!
15:18
philippej
and when you push the "dynamic range" do you get more noticeable noise? (with knees)
15:23
se6astian
yes, fpn gets stronger in those regions
15:23
se6astian
but thats not compensatable at th moment
15:25
philippej
bbl see you

se6astian Bertl Greets. HDMI out is different eh?
15:54
Bertl
of course, a snapshot (raw data) will not go through the output pipeline
15:55
Bertl
i.e. neither the color matrix nor the gamma luts will be applied
15:55
troy_s_
Bertl: how to use the profile then?
15:56
Bertl
I think sebastian is using it for post processing the raw data
15:57
troy_s_
Bertl: is there a way to use it on the HDMI out?
15:57
Bertl
yes, via the matrix and the gamma luts (in the output pipeline)
15:58
troy_s_
Bertl: so what is se6astian having issues with?
15:59
Bertl
I don't think he has issues at all ... but I might be wrong
16:01
troy_s_
Bertl: did you apply the shaper before or after matrix?
16:01
Bertl
the shaper being the linearization unit?
16:01
se6astian
no issues, its all fine now :)
16:02
Bertl
troy_s_: if so, that is in the input pipeline, so it applies to both, the snapshot and the hdmi output
16:02
troy_s_
se6astian: so it worked??

as I wrote in the email I created a new ICC from the HDMI footage
16:10
se6astian
now with that one I can get good results yes
16:11
troy_s_
Did you use colprof and scanin?
16:21
troy_s_
se6astian: Just remember that your output target needs to be 709 / sRGB primaries and bt.1886 transfer curve for the HDMI
16:23
se6astian
I used lprof
16:24
troy_s_
Doesn't matter
16:25
troy_s_
se6astian: ICCs always use an intermediate space (in most cases XYZ with assumed D50)
16:26
troy_s_
se6astian: LUTs and matrix color management can use the data, but they must manually go _to_ their destinations.
16:27
troy_s_
se6astian: Bertl can probably help you go from the XYZ to the proper primaries for 709 and bt.1886
