[. . . ] 9224-2776-21 H-A112 E INSTRUCTION MANUAL BEFORE YOU BEGIN Before installing the DiMAGE Image Viewer Utility 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. Users with Windows 98/98SE or Mac OS 8. 6 will need to install driver software before connecting the camera to a computer. Image data can also be downloaded with an SD memory or MultiMedia card reader. [. . . ] · By placing the mouse pointer on the displayed image, the grey or color level of that point will be indicated on the tone curve by a white circle. · The reset button cancels all corrections in all channels. 32 Drawing tone curves by freehand Click the freehand-curve button (1). · The mouse pointer changes to the pencil tool when placed in the tone-curve box. Click and drag the pointer to draw a new curve. · Extreme image manipulations are possible with the freehand curve tool. 1 To smooth a rough freehand curve, click the smoothcurve button (2). · Nodes will be automatically placed on the curve and can be adjusted with the mouse. · With extreme freehand curves, the smooth curve button may significantly change the shape of the curve. Press the undo button to return to the original freehand curve. 2 33 ADVANCED IMAGE PROCESSING A short guide to tone-curve corrections Highlights The tone curve is a graphic representation of the brightness and color levels of the image. The bottom axis is the 256 levels of the original image (input data) from black to white. The vertical axis is the corrected image (output data) with the same scale from top to bottom. The bottom left portion of the graph represents the dark colors and shadow areas of the image. The middle section represents the midtones: skin, grass, blue sky. The top right section is the highlights: clouds, lights. Changing the tone curve can affect the brightness, contrast, and color of the image. Output 34 Mid-tones Shadows Input This is a simple technique to make a subject hidden in the shadows brighter. Unlike the brightness level control (page 22), this method of correction will not lose details in the highlight areas of the image. With the RGB channel selected, place the smooth-curve cursor on the center of the curve. Look at the displayed image to judge the result. The adjustment can be very small and still have a significant impact on the image. Moving the tone curve down will make the image darker. The contrast of an image can be changed. 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. [. . . ] Click the load button.
