| Thank you for all the suggestions. I shall have a look at lightzone - it seems pretty reasonable. I'll have a play with UFRaw too.
I have looked for an option in Picasa to get it to use the camera's WB setting, but haven't been able to find one. As for RT, there is an option to use the camera's settings, but it doesn't seem to make any difference - perhaps it can't find that info in the files the GX20 creates?
The comments about F-Spot showing the camera-generated jpeg preview make sense, but the files seem to be very large (take a while to display properly and are able to zoom in to the same size when looking 1:1).
Thank you all again. |
