Software darktable

Darktable currently does not support the Hasselblad H4D-50 .FFF files. after checking LibRAW they do support the H4D-50 since 0.19. digikam 7 support it. what would the developers need to support this I can submit the .fff files if needed

thanks

Hey,

I guess a good starting point to see what would be needed for new camera support (as for lots of other questions :wink: ) would be the darktable website:

→ camera support | darktable

I have manage to get darktable to decode the hasselblad h4d-50 files by adding these line to the cameras.xml in the rawspeed folder

    <Camera make="Hasselblad" model="Hasselblad H4D-50">
		<ID make="Hasselblad" model="H4D-50">Hasselblad 50-Coated</ID>
		<CFA width="2" height="2">
			<Color x="0" y="0">RED</Color>
			<Color x="1" y="0">GREEN</Color>
			<Color x="0" y="1">GREEN</Color>
			<Color x="1" y="1">BLUE</Color>
		</CFA>
		<Crop x="48" y="6" width="-42" height="-82"/>
		<Sensor black="256" white="65535"/>
	</Camera>

the problem now is that now the input color profile is throwing an error 'Hasselblad H4D-50" color matrix not found!. any one here knows whether the entry I added above is incorrect. the sensor black and white is correct. I check it in the exif. the only thing is the crop x,y, width and height I am not sure what values are those

hope someone can shed some light
