Sharpening Filters

These filters can increase image sharpness and provide edge enhancement. However

image noise may be enhanced as well. These filters accentuate the high-frequency details

of an image while leaving the low-frequency content intact. High frequency portions of

the image get brighter while low frequency portions become black.

Sharpen level 9 (high) has the largest effect on the image. Sharpen level 5 has an

intermediate effect. Sharpen 1 (low) has the most subtle effect on the image. 9 different

sharpening levels are available for optimization of the image.

3-D (Contour) Filters

These filters are particularly useful for visualizing faint bands. They produce a "3-D"

effect, defining edges and making details easier to see.

3-D level 9 (high) has the largest effect on the image. 3-D level 5 has an intermediate

effect 3-D level 1 (low) has the least effect on the image. 9 different 3-D levels are

available for optimization of the image.

In addition, 3-D allows the user to control the ‘direction’ of the 3-D shadowing effect.

Once the level is refined, just click on a direction arrow to visualize the shadowing

adjustment. The default shadow direction is in the lower right hand corner direction and

9 different directions are available.
