Color Correction and the Sony F5
Recently, Digital Zoetrope Productions worked with filmmaker Daphne Stacey to produce an independent film entitled In A Moment. The film was shot exclusively with our Sony F5 Cinealta Digital Cinema camera and utilized that camera’s S-Log2 gamma curve setting. What the Sony F5’s S-Log2 gamma setting allows you to do, is to record a scene with a “flat” picture profile that keeps most of the original information from the camera’s sensor. Essentially, this profile is as close as the camera can record to a RAW setting without actually using the AXS-R5 RAW Recorder with the Sony F5.
Shooting in S-Log2’s flat profile allows us to color correct the final image immensely without sacrificing image quality. S-Log2 preserves the dynamic range of a shot, meaning that information from both the highlights and shadows are recorded for use by your editing/color correction system. In the case of In A Moment, color correction was done exclusively in Adobe Premiere Pro CC 2014 utilizing a combination of built-in color correction filters and Look Up Tables (LUT) from James Miller’s excellent Deluts collection.
Here is a sample of the difference in the S-Log2 footage and the color corrected footage: (Click to enlarge to their original 4K size)
The above sample was color corrected using Miller’s Liverpool LUT at 20% opacity and Adobe Premiere Pro’s RGB Curves and Fast Color Correction effects. This helped us achieve a dark, somber mood look to the footage.
This sample utilized Miller’s Lichfield LUT at 100% opacity and Adobe Premiere Pro’s RGB Curves and Fast Color Correction effects.
Lastly, this scene was color corrected using Miller’s Lichfield LUT at 100% opacity and RGB Curves and Fast Color Corrector. The saturation was also increased to about 120% since the mood of this scene is more hopeful than the previous two scenes.
