14:55 | polyrhythm | anuejn: ...are we looking at the same DNG?
| |
14:55 | polyrhythm | when I open it in darktable I get a black image and "Unsupported profile replaced with linear Rec 709"
| |
14:56 | polyrhythm | other programs just refuse to open it at all
| |
14:57 | polyrhythm | darktable does kind of open it in the sense that you'll see some purple-y weird thing in the "light table" view, but if you go to develop the image in the darkroom, it's just nonsense data
| |
14:58 | polyrhythm | just to double check i re-downloaded the DNG above and confirmed this behavior
| |
14:58 | anuejn | waaaaaat
| |
14:58 | polyrhythm | so there's definitely something screwy with the metadata, and some apps just can kind of roll with it and at least sort of load it
| |
14:59 | anuejn | jup that is true
| |
14:59 | polyrhythm | profile software (lumariver) straight up refuses to load it. as does adobe DNG converter
| |
14:59 | anuejn | it is also more screwed than my dngs
| |
14:59 | polyrhythm | well your DNGs just load garbled noise for me haha
| |
14:59 | anuejn | since this one I cannot convert with the adobe DNG convertar
| |
14:59 | polyrhythm | right
| |
15:00 | anuejn | do mine load in adobe dng converter for you?
| |
15:00 | polyrhythm | yeah they do
| |
15:00 | polyrhythm | the data is just nonsensical because of the float thing or whatever, but structurally it seems ok
| |
15:02 | anuejn | okay
| |
15:02 | anuejn | I see what is wrong with your dng
| |
15:02 | anuejn | it is lacking the color profile
| |
15:03 | polyrhythm | yeah that appears to be it given the darktable complaint
| |
15:03 | anuejn | did you just bake the dngs with an empty color profile
| |
15:03 | polyrhythm | i guess, I used the base_idf or whatever yml file
| |
15:03 | polyrhythm | i believe with the other yml file, I remember getting the garbled data? i don't remember why i used base
| |
15:03 | anuejn | (this is the metadata diff: https://www.diffchecker.com/tpjOcNT2/)
| |
15:04 | anuejn | ah base_ifd is the wrong one
| |
15:04 | polyrhythm | okay
| |
15:04 | polyrhythm | I'll try this flow again with either the included yml or at least hand-make one that has some pass-through matrices
| |
15:04 | anuejn | as it contains the tags that are written anyway
| |
15:04 | anuejn | sounds good
| |
15:05 | anuejn | it should contain the tags from default_dcp.yml
| |
15:05 | polyrhythm | got it
| |
15:07 | polyrhythm | maybe random question for se6astian but what's the deal with the e-mount lens decision?
| |
15:07 | polyrhythm | it's a completely whack idea from a cinema perspective since it's got a screwy flange distance for adapting any legitimate glass.
| |
15:07 | polyrhythm | standard should be PL...
| |
15:08 | polyrhythm | assuming our target audience includes film people, anyway
| |
15:09 | polyrhythm | I have a P+S Technik lens mount on one of my cinema cameras which is really nice. it is modular and can take PL, C, EF, and others
| |
15:12 | se6astian | we chose emount because we need a short FFD bayonet so any other mount standard can be easily adapted mechanically, MFT was too small for APSC projection circle
| |
15:13 | se6astian | we also considered P+S but since that always requires an adapter did not seem practical to us
| |
15:13 | polyrhythm | in practice for film people, the adapter is a trivial thing practically-speaking, but i see your reasoning regarding the bayonet
| |
15:14 | polyrhythm | i guess i am just myopically am considering the film case. i would want a straightforward plug and play for PL
| |
15:14 | se6astian | what do you mean with " screwy flange distance" ? no locking part like PL mount?
| |
15:15 | polyrhythm | i guess I am not being technically correct, but look at the nonsense involved for adapting a PL-mount properly: https://woodencamera.com/products/e-mount-to-pl-mount-pro-sony-alpha-fs7mkii-fx9
| |
15:15 | polyrhythm | you need like little spacer shims and a support bracket and all this crap
| |
15:15 | se6astian | we are open to design any mechanical native PL mount or other standard but since there are so many adapters out there already the demand has been low to non existance from the community side so far
| |
15:16 | polyrhythm | yeah i guess you would need more high end productions weighing in before you'd see demand for the high-end glass standard like PL
| |
15:18 | se6astian | possibly, from a manufacturing side PL would likely mean steel elements where we currently have aluminum and the question if our current manufacturer can meet the required accuracy, we are also designing shims currently, its unlikely any lens mount that has a defined FFD will be manufactureable without them, just the question if its hidden inside the camera by te manufacturer already
| |
15:19 | polyrhythm | yeah sure. I think my perspective is probably not ideal for a first run of a prototype camera, just trying to provide the perspective of somebody who has invested in a lot of nice cinema glass and would want to use the camera practically on-set
| |
15:20 | polyrhythm | rather than in a lab or in my bedroom, haha
| |
15:24 | se6astian | sure :D
| |
15:24 | se6astian | its still some way to get it out of the bedroom :P
