The DSC Labs DX-1 102-Db 18 Step Grayscale Test Chart is a rear-lit test chart designed for calibrating the resolution on your video camera. It features an 18 step true log pattern and a 17 f/stop dynamic range. The test chart can determine camera performance from the deepest white to jet black.
You can use the DX-1 102-Db 18 Step Grayscale Test Chart as a precision optical signal generator that produces waveform and vectorscope displays similar to standard electronic test signals. In addition, it can be used to align multiple cameras using the color patches. The chart can be used for aligning different types of lighting such as quartz, HMI and fluorescent. It also features a maximum tolerance level of 5 CIE LxUxV units and an RMS maximum of 2 units.
