This 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.

FAQs About Dynamic Range Charts

Our machine is packed by standard export wooden box, it won’t be damaged. We’ve delivered many testing machines abroad by sea or by air without damage.

a. If this phenomenon occurred, it means the battery power is not enough. You need to charge the battery.

b. When charge the battery, please insert the battery to the instrument, and plug in the adapter to charge the battery. After 5 minutes, the instrument can be turned on.

c. If the instrument still cannot be turned on after charging 5 minutes, you can pull out the adapter and re-plug in to check it. Or repeat this operation.

d. If the instrument still cannot be turned on after charging 5 minutes, you can turn off the colorimeter and turn on it again to check it. Or repeat this operation.

e. If you have tried all the methods above but the colorimeter still cannot be turned on, please change the battery.

a. It’s needed to perform manual calibration for NH300 when first starting.

b. In the subsequent starting, no need to perform manual calibration.

c. Suggestion: it’s best to perform manual calibration once a week or when NH300 measured data is not accurate.

Our machine is packed by standard export wooden box, it won’t be damaged. We’ve delivered many testing machines abroad by sea or by air without damage.

After receiving NH310/NH300, you have to perform white and black calibration manually when first starting.
