Canon 2925B002 User Manual - Page 213

Image Settings Sayfa 213 / 302 sayfa Shadows may not be corrected properly depending on the document. If the page background is not white, shadows may not be detected correctly or may not be detected at all. While scanning, press down on the spine with the same amount of pressure you used to preview the scan. If the binding part is not even, the shadow will not be corrected properly. How to place the document depends on your model and the document to be scanned. Note Cover the document with black cloth if white spots, streaks, or colored patterns appear in scan results due to ambient light entering between the document and the Platen. If the shadow is not corrected properly, adjust the cropping frame on the preview image. Adjusting Cropping Frames Exposure/Tone Settings (Film only) Manual Exposure This function enables you to adjust the exposure data according to the film. This checkbox is not selected by default. When this checkbox is not selected, the optimal exposure data (the exposure level for each RGB channel and compensation levels) is automatically set according to the color density of the portion within the cropping area of the film. Select this checkbox if you intend to adjust the image using an application after it is scanned or to scan with an under-exposed or over-exposed effect. After you select this checkbox, you can adjust the exposure in 1% increments within the range of 50% to 200%. Selecting this checkbox sets Auto Tone to OFF. Important Manual Exposure is not available in Basic Mode. To change exposure, select the Manual Exposure checkbox in Advanced Mode, then adjust the value and scan. Note When this checkbox is not selected, the time required for scanning varies by film since the exposure is automatically optimized according to the film. Apply the tone value to all frames (crops) Apply the tone value to all frames is displayed in thumbnail view, and Apply the tone value to all crops is displayed in whole film image view. Click OK to reflect the color adjustment data of the selected film frame or the portion within the selected cropping frame into other frames. This color adjustment data will be used in subsequent scans. It will remain in effect until you click Reset. This is useful when you want to scan film of photos taken on the same day in the same place, in a consistent color tone.
