Windows software used a "sharpen" filter

| I've sort of got proof that the Windows software used a "Sharpen" filter...
The picture below is the linux generated picture above, ran through the gimp's "sharpen" filter, and finely adjusted to match the Windows scan above.
You'll notice, only the colors are off now.
I believe that scan manufacturers are more concerned with making the scanner "Look better" than "Look correct". This is similar to how TV manufacturers turn on "Red push" and crank the sharpness control up on the default settings in order to make reds more vibrant and make the low resolution of TV look sharper. |
