36-Patch Dynamic Range Test Chart
This 36-Patch Dynamic Range Test Chart has 36 low-noise density patches
with density steps of approximately 0.1, for a density range of at
least 3.2 (density from base to base + 3.1 minimum). A nearly circular
patch arrangement ensures that vignetting has minimal effect on
results. A CSV reference file with actual densities will be
supplied. The chart has an active area of 197x235 mm
(7.75x9.25 inches) on 203x254 mm (8x10 inch) film.
It
also contains slanted edges in the center and corners with 4:1 contrast
for measuring MTF. The edges have an MTF50 >= 16 cycles/mm,
which is about 3 times better than the best inkjet charts. Registration
marks make the regions easy to select. A neutral gray background helps
ensure that the chart will be well-exposed in auto exposure cameras
(compared to charts with black backgrounds, which are sometimes
strongly overexposed).
It
is supported
by Stepchart, Multicharts, Multitest and
can be used with the Dynamic Range postprocessor if
several manual exposures are available. Dmax >= 3.4 is
sufficient for camera phones and digital cameras with small pixel
sizes, but high-end DSLRs generally have higher dynamic ranges (and
also manual exposure), which makes them well suited
for Dynamic Range.
This
chart is produced with a high-precision LVT film recording process for
the best possible density range, low noise, and fine detail.
