00:16

:)
00:16

but the page for 1/1/2015 exists http://irc.apertus.org/index.php?day=01&month=01&year=2015

I did not expect anyone would still use my irc log viewer in 2015 :)

morning folks!

heh, 'morning'

I have a question for anyone who knows about debayering;
17:32
intracube
if you have a standard RGB sensor and are shooting a monochromatic scene, could the debayering process make use of the different positions of the RGB sensels to create a genuinely higher resolution image?
17:33
danieel
that is done always, as the debayer resolution is the resolution of the sensor. next?
17:33
intracube
assuming the scene is the correct colour temperature and fills the RGB sensels equally
17:36
intracube
danieel: can the correct layout for the sensor always be derived? as in some sensors are:
17:36
intracube
RGRGRG
17:36
intracube
BGBGBG
17:36
intracube
and others might be:
17:36
intracube
RGRGRG
17:36
danieel
there are 4 layout
17:36
intracube
GBGBGB
17:36
intracube
offset greens
17:37
danieel
greens are always offset, never next to each other
17:37
intracube
and don't Sony have some diagonal sensor design?
17:37
danieel
it is practically same
17:38
danieel
magic in the marketing :)

17:40
intracube
top design looks a bit wild :)
17:41
danieel
patents are often scifi :)
17:41
intracube
fair point

17:48
intracube
see! greens in rows
17:49
danieel
that is for HDR :)
17:50
danieel
its normal bayer, twice, offset by half-bayer pixel width

would there not be much difference in sharpness between the colour and BW alternatives of the Axiom sensors?
18:41
danieel
sharpness should be the same, sensitivity will be different
18:42
danieel
assuming the mono sensor is achromatic... lookup the QE curves
18:46
intracube
thanks danieel
18:51
danieel
in theory the bayer pattern one could be sharper (or differently unsharp)
18:52
danieel
in case of "poor" lens, which visibly separate/shift the colors (eg at edge of image)
19:23
intracube
yep
19:23
intracube
quite a few advantages of shooting in colour even if the final product is going to be BW
19:48
danieel
of course, simulation of color filters to change the distribution curve is easy if you shoot in color
