Can't help with photek, but I've assisted on several Cinematic Orchestra sessions - mainly drum recording. The drums we did were done near the end of the track's production - the talented Luke Flowers on kit - tracked to PT through Neve VR (no fancy outboard plugins, the usual 87s/414s/421s etc as mics) in a nice wood room, and then mixed to stereo against the backing track.
One of the tracks was then mixed on the VR, the other Jason took away stereo drum parts to integrate into the track.
The other parts of the tracks...well I don't think there was much that was done unconventionally! I think it was all multi tracked though - not a lot of playing together in a room. Mainly down to great arrangements.
