Description
Substrates
These charts are produced on either photographic film with a high-precision LVT film recording process for the best possible density range, low noise, and fine detail, or on a translucent inkjet film.
LVT Film Resolution
The edges have an MTF50 >= 10 cycles/mm, which is about 2 to 3 times better than the best inkjet charts. The large patterns are fine enough to produce good results with up to 30 megapixel cameras.
Inkjet Film
The edges have an MTF50 >= 4 cycles/mm. The large patterns are fine enough to produce good results with up to 10 megapixel cameras.

Documentation and software support
SFRplus can be run either through the highly-interactive Rescharts interface or as a batch-capable fixed module. The key documentation for getting started is Using SFRplus Part 1, found in the SFRplus section of the Documentation page. We recommend framing the chart with a small amount of white space above and below the top and bottom bars. Badly-framed charts can be analyzed with SFR using manual ROI selection.
