Ottocolor was designed with the user in mind. Initially, the process of color correction involved mainly the vectorscope to accomplish this task. After extensive research, we simplified the work process to a minimum and designed Ottocolor target to meet this requirement.
After testing various materials and consulting with professionals, including a top-tier restaurant menu manufacturers and a bookbinding cover manufacturers, we ultimately selected the perfect materials for their robustness and durability.
The interior of the target required a frame to protect the surface of the color targets and the delicate darkest sample.
The Ottocolor method begins with white balance and exposure. The brightest white is measured at >95 IRE, providing ample room for adjustment. Next is the middle gray, commonly referred to as the 18% gray. This is used to calibrate the shot. Once you have determined your top exposure in the REC.709 IRE scale, divide it by half to obtain the middle gray. Repeat the process for the next darker gray.
The bottom left of the color target contains the darkest material when perpendicular to the camera. This provides a baseline that can be adjusted later while correcting the shadow exposure of both LOG and Rec.709 videos.
The top row begins with red and ends with magenta, all calibrated at 25 IRE chroma. The skin tone is calibrated to narrow down to a single line with a 20 IRE chroma. The main difference with other color correcting workflows, is that Ottocolor method uses the RGB overlay and Chroma waveforms to achieve true color easier and more accurate than just using the vectorscope.
To achieve consistency, large color panels meticulously calibrated for each color are then cut to size to maintain consistent color quality across each unit. Each calibrated panel is divided to make close to 400 units.
