Bertl: good news - i wrapped my head around the basic process in freecad-pcb now after some initial struggling and i think i'll be having a lot more components on the board real soon (most might in fact be in the default library already, but let's see) :) http://fdpl.foundation/pcbs.png

general photography for the sensor gurus. does the native iso explanation in this article make sense: https://www.slrlounge.com/workshop/optimal-iso-settings/
17:28
intracube
*general photography question
17:28
intracube
I was under the impression that there is only one native ISO setting
17:29
intracube
and all other ISO settings either change the analog gain on the sensor hardware
17:30
intracube
or do an equivalent digital gain
17:31
niemand
intracube, the article suggests that the cameras can do multiple levels of analog gain (equivalent to the 1x, 2x 3x gain of the beta)

niemand: or might it mean that for the Canons, ISO values of 100, 200, 400, 800 control the analog hardware gain, and the inbetween values happen further down the chain as digital processing?
17:34
niemand
intracube, yeah, i think so
17:36
intracube
the next part doesn't make much sense whichever way it's read
17:36
intracube
"ISO 250 will actually yield more grain than if you were to shoot at ISO 400 and pull it down in post production."
17:37
niemand
because 250 is analog+digital in camera and 400 is analog only
17:37
intracube
right, but analog gain will increase noise. no such thing as a free lunch :)
17:37
intracube
maybe the appearance of the gain would look slightly different
17:37
niemand
but less than digital
17:38
niemand
but if you want to know it quantitatively, measure it
17:38
intracube
yep, I've been shooting sets of images this evening
17:41
niemand
and computed snr?
17:44
intracube
I don't know how to do that, so just a visual check for now

swym_staff
looking for some help on documenting stuff
21:06
swym_staff
looking for 3 main things
21:06
swym_staff
1. list of all the boards (modules, plugins, main board, power board, etc)
21:07
swym_staff
2. PCB CAD locations of all those boards
21:07
swym_staff
3. Github locations of all those boards
21:08
swym_staff
#3 being the software locations for the boards (stuff like the lattice FPGA code, the zynq code, etc)

having a hard time tracking everything down in its current state at https://github.com/apertus-open-source-cinema
21:10
swym_staff
any pointers would be great

starting point at least...
21:47
swym_staff
grabbed the eagle cad files from an update post from 12 of 2014
21:47
swym_staff
so.... probably pretty old
