[. . . ] To activate the Level Adjustment or Tonal Map functions, click on the Advanced. . . button at the bottom of the Balance tab. When this button is selected, the Level Adjustment window is displayed by default. Scanning 3. 9 Level Adjustment The Level Adjustment dialog box shows the distribution of brightness levels in your image. To adjust the histogram plot, drag the triangles, located below the horizontal bar to the desired values. The left (black) triangle changes the shadow levels. The right (white) triangle changes the highlight levels. The middle (gray) triangle controls the midtone levels. Level Adjustment tab Highlight control Shadow control Midtone (Gamma) control By varying the Shadow and Highlight points you can change the relative shades and highlights of the image. The Shadow point represents the darkest value and the Highlight point is the brightest value. The Midtone point represents the Gamma setting for your particular screen. On the histogram, the Shadow and Highlight scales are divided into 255 units. Therefore, all pixels in the original that are darker than the current shadow point are now completely black in the enhanced image. Conversely, all pixels in the original that are brighter than the current highlight point are now completely white in the processed image. Setting the highlight point to 200 renders all pixels greater than or equal to 200, on the original, completely white in the processed image. Similarly setting the Shadow point to 200 renders all points less than or equal to 200, on the original, completely black in the enhanced image. Photographers often refer to these effects as high-key or low-key. High-key is an image pushed to the white end, and low-key is an image pushed to the black end of the tone curve. 3. 10 Scanning The Midtone is a relative measure of the gamma of your monitor. The scale for Midtone ranges from 0 to 255. This means that at a value of 255 it tends to infinity. The Midtone is bound by the Shadow and Highlight terms and cannot exceed them at any time. So, if the Highlight is set to 255 and the Shadow is set to 0, a gamma of 1 is equal to a Midtone of 128. Similarly, if the Shadow is set at 200 (lower boundary) and the Highlight is set at 220 (upper boundary), a gamma of 1 is equal to a Midtone of 210. Operation: 1. This will display the Level adjustment window. On the histogram, use the mouse key to click on the black, gray , or white triangles to make changes to the Shadow, Midtone and Highlight respectively. To see the changes and compare them to the original previewed image, click on Sample 1 to see the enhanced image. [. . . ] Always use the same image cartridge with the same printer. Using a cartridge that has already been used in another printer may not give satisfactory results. Character voids The paper may be too dry. Try printing with a different batch of paper.
