The DSC Labs OneShot chart is designed to capture as much camera and scene lighting information in one shot as possible so that dailies look as close to the DP's intent as possible. Matte Finish - unlike most other DSC Labs charts, the OneShot is printed with a matte surface to reduce obvious reflections. Glossy charts offer improved dynamic range as blacks can be made deeper and whites brighter, but film-style production schedules don't generally allow the time necessary to shoot a glossy chart and eliminate reflections. A matte chart will still show some glare if held at an improper angle to a light, and the contrast range of the chart is not as high, but it is overall much faster to shoot accurately in a high pressure and timesensitive shooting environment.
The Grey Scale
The left column on one side of the One-Shot chart contains black, grey and white chips. The grey chip is the most important as it is calibrated for 18% reflectance—the same as most spot meters. Placing this grey chip at your preferred middle grey waveform reference point (usually around 40 IRE, but can vary based on taste, camera manufacturer or DP preference), helps to ensure that mid-tones, such as flesh tones, are rendered accurately. DSC’s 90% CamWhite and Acuflect black chips provide optimum white and black balancing.
(An improper black balance can throw off the entire color balance of a scene and result in some very ugly looks.) Additional larger 18% grey and white patches are included on the back of this chart.
The Flesh Tone Row
The first thing a colorist does in a grading session is to look for flesh tone. Improperly rendered flesh tones are more distracting than any other color problem: we innately know what flesh tone looks like, and if it's wrong, nothing else in the scene will appear right. The OneShot's flesh tone row shows the colourist four common flesh tones, all of which fall along the I-Q line on a standard vectorscope.
The Colour Rows
The ITU-709 high definition broadcast standard defines three standard primary colours--red, green and blue--out of which are created three standard secondary colors--cyan, magenta and yellow. These hues are reproduced on the OneShot chart and, when properly white balanced in a grading session, these colours should line up with the red, green, blue, cyan, magenta and yellow target boxes on a standard ITU-709 vectorscope.
