Hello Ton, when you say the 'linear' RGB images look OK on your monitors,
are there any lookups being applied (ie. gamma correction)?

Regardless, you should probably avoid cineon since it requires you to
go through a printing density (log) pipeline.  Your images already look
good on your monitor and your monitor is essentially video, so the images
should stay in video.  That leaves you with DPX.  But if you are viewing
the images with a lookup table to do gamma correction, then you might need
to bake that lookup into the DPX pixel values.

Good luck.  I look forward to seeing your film.
