SineZone^® – 4K Sinusoidal chart

Besides showing resolution, SineZone also serves as a visual tool, allowing user to identify chroma moire. This useful chart also identifies aliasing, which shows as circles within the pattern. Limiting resolution can be measured by calculating linear distance from center of chart along a radius to the point at which detail has lost enough contrast to be no longer visible.

Warning: This chart has been designed to be very hard for any camera to reproduce accurately.
