Scanning Option

Image Type

Lets you to select the color mode for your scanned images. The default color mode is Color. Other options include Gray, Gray 16 bits, BW and Color 48 bits.

Resource Type

Selects the resource type of the original.

Scan Resolution

Sets the scanning resolution.The default resolution is 600 dpi. You can also choose the following resolutions: 75, 100, 150, 200, 300, 600, 1200, 2400, 4800, 9600 and 19200.

Output Size

Sets the output size of your scanned image.

Descreen Selection

If you are scanning images from magazines, newspapers or other printed materials, the scanned image may appear to be covered by tiny screen patterns. To eliminate this pattern, choose the kind of original you want to descreen from this drop-down list. EPSON Scan Tool Light will automatically descreen the scanned image.

Output Information

This section allows you to make the following settings: Scaling, Linkage, Document Width and Document Height.

Hint

This section offers you information about each function.

Color Adjust

Click the  Color Adjust tab and a menu will appear in which you can define various items. There are five settings in this menu:  Brightness and Contrast Adjustment,  Color Balance Adjustment,  Curve Adjustment,  Level Adjustment and  Hue and Saturation Adjustment.

Adjust Brightness and Contrast

This item allows you to adjust the brightness and contrast of the scanned image.

You can enter values between -100 and 100 (the default is 0) in the text boxes. You can also drag the scroll bar left to decrease or right to increase the effect. We recommend you click the  Auto button to let the software adjust the effect automatically.

 Load

Retrieve previously saved settings.

 Save

Save settings.

 Reset

Reset either brightness or contrast to its default value.

 Reset All

Reset both brightness and contrast to their default values.

 Auto

Click the Auto button to let the software adjust the effect automatically.

Adjust Color Balance

With the Color Balance menu, you can change the mix of colors in an image and emphasize or diminish certain colors.

To adjust the color balance, first, select the channel you want to adjust, then drag the triangles under the three color bars. You can also enter the desired values directly into the three text boxes to the right of the color bars.

For example, if the color of the brighter area in the original you scan appears to be bluish, you can first choose Highlight as the channel, and then drag the triangle under the Cyan-Red bar to the right, or drag the triangle under the Yellow-Blue bar to the left to eliminate the bluish effect.

Adjust Curve

The Curve tool is used to adjust the brightness properties of midtone pixels in an image.

Use the boxes to the right of the Curve tool to select the color channel to be adjusted. This allows you to adjust the curve property of each color channel individually.

The x-axis in the Tonal Map represents the input brightness level of the pixels in an image. The y-axis represents the output brightness level of the image. By clicking and dragging the curve to change its shape, you can adjust the difference between the input and output brightness levels of an image without extensively modifying the dark and bright areas. Compare the following images and their Tonal Maps:

For the original image, the curve is straight and diagonal.

Drag the curve to the left, and the mid-tone area of the image becomes brighter.

Drag the curve to the right, and the mid-tone area of the image becomes darker.

You can also click the curve to add new points and further change the shape of the curve:

You can see the exact input and output values in the Input/Output Status Area.

Reset All

Adjust Level

The Color Level dialog box shows the distribution of brightness levels in an image. It also shows the exact brightness value for each color, or for the combined colors, in the Input Level and the Output Level boxes.

Use the boxes to the right of the histogram to select a color channel to adjust. (This allows you to adjust the histogram property of each color channel individually.)

A histogram displays the distribution of dark and bright pixels in an image. The x-axis represents the brightness level that is divided into 256 (0 to 255) equal portions. The y-axis represents the quantity of pixels in each brightness level. A comparison of two images and their histograms follows:

Brighter images have brighter pixels, so the bars to the right will be higher than those to the left.

Darker images have darker pixels, so the bars to the left will be higher than those to the right.

In the first image, there is a higher contrast between the brighter and darker parts of the image. Bright and dark pixels occupy a larger portion of the total image. Therefore, in the histogram there are higher bars in the left (darker side) and right (brighter side). In the center the bars are much lower, which means that there are only a few midtone pixels in the image.

In the second image, pixels in objects possess greater levels of brightness and darkness. The distribution is more even than in the first image, which makes the histogram for the second image appear more even.

To adjust a level, first choose the color channel. There are four radio boxes for the selection of channels. If you select Master, the levels of all three color channels (red, green and blue) will be adjusted simultaneously. If you the Red, Green, or Blue box, then only the selected color channel will be adjusted.

Next, you can adjust the level by dragging the triangles under the diagrams. The black triangle (the left one) is for the adjustment of shadow, the gray triangle (the middle one) is for mid-tone, and the white triangle (the right one) is for highlight. In addition, you can adjust the values by entering the desired values in the text boxes. You can also press the  Auto button to let EPSON Scan Tool Light automatically adjust color levels.

The images below show the results of using the Adjust Level histogram tool to adjust brightness and add detail:

Adjust Hue and Saturation

Hue describes where a color lies on the color spectrum, while Saturation is the intensity of a color.

You can use the color map to specify the hue and saturation of the color you want to use. Move the mouse cursor over the color map wheel and then click on it. Drag inside the color map wheel to select the hue of the color you want to use. The distance from the center of the wheel determines the saturation of the color: the farther you drag the mouse cursor from the center of the wheel, the higher the saturation.

You can drag the triangle under the bar to make the color you're adjusting on the color map wheel lighter or darker. To make a color lighter, drag the triangle to the right. Drag the triangle to the left to make it darker.

You can see the settings change in the Hue Angle, Saturation, and Lightness boxes when you drag within the color map wheel or adjust the sliding bar. You can also enter values directly in these boxes.
