| 06:48 | Phil_y_Ceee | Good morning dear Axiom Crew,
|
| 06:49 | BAndiT1983|away | changed nick to: BAndiT1983
|
| 06:51 | Phil_y_Ceee | thanks for the update on development in progress - great, informative article, nice layout, describes the (open) tasks on point, and outlines the obstacles ahead.
|
| 06:55 | Phil_y_Ceee | i really apreciate working with small tools, like dslr/dslm/panasonic eva1/arri mini/canon c200 - but running only a test shoot on the beta with the complete signal stream (from sensel to screen) available, open and one day delivering 240+ frames.. i start smiling on that imagination ;)
|
| 06:56 | Phil_y_Ceee | Enjoy your day!

| 10:07 | janosch_ | hey all myname is janosch simon and i got the tip from sebastian pichelhofer to ask my camera calibration question here . :)
|
| 10:10 | janosch_ | i have a smal camera which i call miniraw 2 it is based on a point grey camera grasshopper 3 with sony imx174 it writes .raw files with no header and a friend of mine and i made a converter to .dng which works but the calibratiion matrice i use are crap :( would like to know if there is a software that i can feed a .raw image and spit out the calibration matrix :D
|
| 10:12 | se6astian | alexML: is the one you want to chat with
|
| 10:13 | janosch_ | mkay :) im a irc noob HOW :D
|
| 10:19 | se6astian | by waiting for him to reply here for example
|
| 10:19 | janosch_ | easy ;) thx
|
| 10:27 | danieel | janosch_: what calibration?
|
| 10:27 | danieel | fpn/darkframe or color matrix?
|
| 10:29 | se6astian | changed nick to: se6astian|away
|
| 10:29 | se6astian|away | changed nick to: se6astian
|
| 10:30 | danieel | for the color matrix, the easiest approach is to take a shot of an xrite color checker and then use their tools to load the dng which spits out an icc profile (which is esentially a "dng" without picture), you can use both the matrix (base correction) and color equalization (advanced fine tuning) from that, and add those tags to your DNG
|
| 10:30 | danieel | the calib is of course subjective to your lighting conditions

|
| 10:33 | janosch_ | thx daniel :) this i alread did but i dont like the result :( with there you mean the adobe dng thingy?
|
| 10:35 | janosch_ | also im not shure if i need all the other forward matrix stuff and different illuminations hmm end goal is to use the dng in davinci resolve with srgb setting earlier route was to use the bmd linear profil but then the colors are totaly off :/
|
| 10:42 | danieel | i was doing fine with one matrix only
|
| 10:42 | danieel | if you use overrides like "bmd anything" then it is not using your matrix
|
| 10:43 | danieel | check in darktable/rawtherapee first, there you can see whether and how is your matrix used
|
| 10:45 | janosch_ | HMMMMMMMMM building a own diy camera is satisfying but not that easy hihi but i like the results rawtherapee is a software right? hmm hmm

|
| 10:49 | danieel | yes, its sw
|
| 10:51 | janosch_ | when i open a dng sequenz in resolve i get the "best" look so far when i leave the dng import settings to std which i believe is srgb then my matrix should be loaded?
|
| 11:01 | danieel | try to change the matrix and you will know
|
| 11:01 | danieel | i dont use resolve
|
| 11:04 | janosch_ | mkay which software you use?

|
| 12:47 | danieel | Bertl: do you have some spi waveforms (or what the interface for cmv is?) (in form of a binary stream, either capture from LA or simulation.. also VCD export would be possible to accept from ILA)
|
| 12:48 | danieel | im working on some reverse engineering tool that decodes various protocols - into a very high level interpretation - like e.g. sensor regs
|
| 12:51 | Bertl | on the CMV it is just plain old SPI, nothing special
|
| 12:52 | Bertl | i.e. you can generate those waveforms with an RPi or MicroZed with the built in peripherials
|
| 12:57 | danieel | i do not want to generate it, that defeats the principle that i want to reverse it... knowing what is there is not that much of fun
|
| 12:57 | danieel | was rather into a realworld example, with timing as in real cam
|
| 12:58 | danieel | plus you need to trigger the sensor here, config is not enough
|
| 12:58 | Bertl | sorry didn't bother to record plain old SPI yet
