BEFORE YOU BEGIN Before installing the DiMAGE Viewer software, read the data-transfer section in the camera manual. This section details how to connect the camera to a computer using the supplied USB cable. The s in this manual assume the camera is connected to the computer with a USB cable as described in the camera manual. [. . . ] The light blue 45° line on the tone-curve graph represents the original contrast of the image. Making the angle of the tone curve greater than 45° will increase the contrast of the image. Making the angle less than 45° will reduce the contrast. With the RGB channel selected, click on the tone curve near the top and bottom to add two nodes. This will increase the angle of the central portion of the tone curve and increase the contrast of the image without making an overall change in image brightness. Correcting color By selecting individual color channels on the tone curve, adjustments to the overall color of an image can be made. This can be used to eliminate unnatural color casts or add warmth to a picture. If the image is too red, green, or blue, simply drag the corresponding color-channel curve down until the color appears natural. If the color cast is predominantly one of the secondary colors, cyan, magenta, or yellow, move the curve of the complementary color up. For more on color, see page 35. 51 WHITE, BLACK, AND GRAY-POINT CORRECTIONS On the tone-curve / histogram palette, corrections can be made by specifying a white, black, and gray point within the image. Locating an appropriate neutral area within the image is critical to correctly calibrate the software. When the dropper tool is selected, the RGB display is active and can be used to evaluate the image area. All changes are immediately reflected in the displayed image. Click the white-point button; the mouse pointer changes to the white dropper tool. With the dropper tool, click on the brightest neutral area of the image to define it as the white point. The default level for the white point is 255 for each RGB channel. Click the black-point button. With the dropper tool, click on the darkest neutral area of the image to define it as the black point. The default level for the black point is 0 for each RGB channel. 52 ADVANCED IMAGE PROCESSING Click the gray-point button. With the dropper tool, click a neutral area of the image to be defined as the gray point. The brightness level of the area is not important, but if the area has a definite color, the image will not be color balanced correctly. Click and hold the apply button to show the change on the histogram. Click the reset button to cancel all corrections. 53 SETTING THE WHITE AND BLACK-POINT VALUES The white and black-point values are set to 255 and 0 for each RGB level. Changing these values allow the calibration of an image with no true white or black. This is an advanced image-processing tool. Double-click on either the white-point or black-point button to activate the point-value-setting dialog box. Input the new white-point or black-point values. With the point-value-setting dialog box open, the mouse pointer can be used to measure the color of any point on the displayed image. Press the shift key (Windows) or command key (Macintosh) to display the CMY levels in the RGB display. The RGB display shows the original values for the image on the left and the current values for the image on the right. Calibrate the image following the steps in white, black, and gray point corrections section. 54 ADVANCED IMAGE PROCESSING TONE-CURVE / HISTOGRAM AUTO SETTING Click the auto-setting button. The auto-setting function automatically adjusts the tone curve and histogram to maximize image data.
