Developed around Hasselblad's patented virtual drum design and flexible magnetic holder and incorporating a 3x8000 optic CCD sensor and a Linos (Rodenstock) lens, both scanners are fast, easy-to-use and offer unparalleled image quality. They also feature a new time-saving facility ­ an `Auto Scan' button, which with one press automatically delivers a superb, high resolution scan. The Flextight X1 scans 35mm originals at a maximum non-interpolated optical resolution of 6300 dpi at a maximum speed of 60MB per minute while the Flextight X5 scans 35mm originals at up to 8000 dpi and at 300MB per minute, making it the world's fastest, high-end scanner. [. . . ] Look for areas that are burned-out (showing values of 255) and also check the shadow areas to be sure you have not hidden any details in these areas. You can undo your settings by selecting Edit -> Undo or pressing cmd-z on your keyboard. · 92 93 The Gradations Window Introduction The functions described in this section will not always be needed during normal operation. They enable you to make fine adjustments to your output images that will affect brightness and contrast and will compensate for printing conditions. As with the advanced highlight and shadow controls, take care when using the Gradations settings. Take notes on the kind of settings you use and make a comparative proof print. To open the Gradations window, type cmd-2 or click on the Gradation button in the Correction area of the main FlexColor window, or select Gradations from the Windows menu. The Gradations window includes sliders for Contrast, Brightness, Gamma and Shadow depth. It also includes a gradation curve, which is a plot of input brightness (on the horizontal-axis) versus output brightness (on the vertical-axis). You can hide or show the curve by clicking on the 94 small triangle beneath the Shadow depth slider. All of the settings you make using the curves and sliders in the Gradations window are saved with the current setup. The contrast, brightness, gamma and shadow depth settings can also be adjusted using the Contrast tab of the Setup window. Using the Sliders The sliders provide a quick and easy way to adjust the contrast, brightness, gamma, and/or shadow depth of your images. These adjustments affect the image, but are not reflected on the gradation graph that appears at the bottom of the window if you click on the triangle. The sliders behave as follows: · Contrast: This control affects the contrast in the image. Positive values increase contrast in the overall image by compressing the contrast in the highlight and shadow areas. Negative values reduce contrast in the midtones, but improve visibility at the extremes of the tonal range. This control is easy to use, but is less precise than using the curve. · Brightness: This control affects the brightness of all points in the image. This control is easy to use, but is less precise than using the curve. · Gamma: The gamma setting applies a predefined gradation curve. However, unlike the standard gradation curve, the gamma setting is strictly controlled, so it enables you to use a color management program that is calibrated to the scanner at a given gamma setting. If you raise the gamma setting, then the image will become lighter and more details will be visible in the dark areas. · Shadow depth: This setting controls a complex algorithm that affects the level of detail visible in the shadow areas of your image. [. . . ] Scanning Resolution: To scan to a fixed fraction of the full resolution for each format, enter a percentage value here. Adapt to format: As an alternative to the controls above, you can instead set your scans to fit to a specific output size. To use this option, mark this check box and then specify your output size using the height and width fields provided next to the check box. Output PPI: Set this to the output resolution you would like to define for the file. [. . . ]
