Hello,
I believe I found a problem with demosaic algorithm auto-selection when using Fuji RAF files.
I’m using Siril 1.06 and use RAF files from Fujifilm X-T20 camera (X-trans sensor).
In Preferences, in FITS/SER debayer section, I have selected RCD interpolation (default)
When I select RAF files (Conversion tab), then check Debayer option, and click on ‘Convert’
I see following from Console output:
…
16:29:25: XTRANS Sensor detected.
16:29:25: AHD interpolation…
16:29:25: Reading RAW: file X20T0113.RAF, 3 layer(s), 6032x4028 pixels
16:29:25: Saving FITS: file lc_00096.fit, 3 layer(s), 6032x4028 pixels
16:29:29: Decoding Fujifilm X-T20 file (ISO=400, Exposure=30s)
16:29:29: Daylight multipliers: 2.293166, 1.000000, 1.612216
16:29:29: XTRANS Sensor detected.
16:29:29: AHD interpolation…
…
Why it shows AHD interpolation ?
It never selected anywhere. It generates files with wrong colors.
I guess correct would be to use Markesteijn interpolation but it cannot be selected manually ?
Thanks
Andy
Because you ask for a debayer directly from the RAW image. In this case this is LibRaw that makes the job. At least in 1.0.x branch of Siril. Markesteijn interpolation will be used only if you work on FITS as specified in Preferences.
Thanks for the response.
How I need to do it properly to enable Markesteijn interpolation ?
I only have a set of raw light frames, no calibration files. Just need to align them and stack. What is the best method ? Thanks
sorry, may be you mean debayer in Per-processing tab ? Without specifying flats, biases or darks , processing cannot be started there (button not active). Still not understand how to do it properly…
