08:44
se6astian
ok, thats fine

I watched Oscar's short film (Spring of Cesar) on the weekend with my girlfriend. It's really good! Great imagery and performances.
08:44
Sasha_C
I only wish things were a little more resolved at the end :(
08:53
se6astian
ah great, you got the dvd in geneva?
08:55
Sasha_C
yep
08:56
Sasha_C
I was surprised with how nice the footage looked, seeing that it was shot on a 5d Mk II.

yeo
11:15
mars_
yep
11:15
se6astian
great!
11:16
se6astian
Bertl, should be awake soon, he will be able to give you an update on the latest tech development progress
11:16
se6astian
I can in the meantime answer any general project questions you have
11:17
mars_
thx, i'll just lurk here for a while
11:17
se6astian
good :)
11:38
Bertl
morning everyone!
11:39

ok I am off to pick up the acryl glas for the prototype enclosure
11:48
se6astian
they replied that order is finally ready for pick up :)
11:48
Sasha_C
Sounds awesome! Good luck

mars_
pix or it didn't happen!
14:06
se6astian
I see you already fitted in perfectly ;)
14:07
se6astian
I left it in my car, doesnt look that spectacular they way it is packed
14:14
Bertl

mars_: are you subscribed to the development mailing list?
14:53

not yet

14:58
Bertl
check with se6astian, he will probably invite you to the relevant mailing lists/forums
14:59
se6astian
will do right away
14:59
mars_
thx
17:21
Bertl
mars_: so any comments on the sensor adapter yet?

Bertl: excellent job!

About that sensor, are such defects to be expected or is it because it's a particularly low-grade sample?

dmj_nova: the ones on the right I'd say can be expected, at least for lower grade
21:19
Bertl
the one on the left seems extreme
21:20
dmj_nova
yeah, the ones on the right can likely be smoothed out without much notice too
21:20
dmj_nova
the one on the left...not without severely limiting the dynamic range
21:21
Bertl
the funny thing is, when scaling down, as in the commentary picture, the effects on the right basically disappear without even removing them
21:22
Bertl
so I'd say, if you know that a particular column is bad, it's rather trivial to remove
21:23
Bertl
from the way the sensor works, I don't think that you can get any 'row' failures, only bad pixels and those column failures
21:26
dmj_nova
Yeah, you could probably even retain some of the detail observed by the row while color/brightness correcting it based on adjacent rows
21:27
dmj_nova
(to avoid aliasing issues)
21:27
dmj_nova
actually, no, not quite
21:28
dmj_nova
if an entire row is stuck, it won't observe anything
21:28
Bertl
I guess there will be different errors
21:28
Bertl
if you check the effects on the raws (right side) you already see a bunch of different effects
21:28
dmj_nova
but the adjacent rows may be part of its RGB pixel
21:29
dmj_nova
so perhaps part of the process will be to characterize the effects.
21:29
dmj_nova
and build a program for it.
21:29
Bertl
yep, and I guess we will see many different ones over time :)
21:30
dmj_nova
Will these defects change over time?
21:31
Bertl
no idea
21:32
Bertl
but I guess it would help to have some kind of calibration routine which detects changes and maybe even allows to address them
