Trials and Tribble-ations [SEP] Directing, cinematography, and music
A number of directors were considered for the episode, with Jonathan West being given the job. West had previously been the cinematographer on staff for both "Deep Space Nine" and "The Next Generation", as well as directing several episodes of the franchise. He had nine days of preparation time before shooting began. He sought to match the same production values as "The Original Series" but found that lighting style and color saturation to film had changed in the intervening years. Visual effects supervisor Dan Curry directed some of the second-unit sequences, and together with West and cinematographer Kris Krossgrove worked to rectify these issues.
