Saving and Opening Images Choosing a File Type The image in the active image window can be saved under a new name by selecting Save As... from the File menu. The Save As dialog for your operating system will be displayed; after navigating to the desired drive and folder, enter a name for the image, and select a file type from the options available, then save the image. Files saved in a format supported by Nikon Scan can be opened in the Nikon Scan applet using the Open... option in the File menu. Choosing a Compression Ratio JPEG and PICT images can be compressed using JPEG compression, in which images are divided into blocks eight pixels on a side and detail within each block selectively reduced. Although raising the compression ratio decreases the file size, it also makes the block pattern more visible and may result in noticeable loss of detail (the actual effect depends on the output scale and the type of subject). It is recommended that you save files at the lowest compression ratio possible; if necessary, you can always save them again at a higher compression ratio. The compression ratio can be chosen using the compression type menu in the Save As dialog. Five options are available, ranging from Excellent Quality, which offers the lowest compression and highest image quality, to High Compression, which offers the highest compression and lowest image quality. Nikon Scan supports the following file types: Format Description NEF, or Nikon Electronic image Format, allows information on curves, color balance, LCH set- tings, and Unsharp Mask to be saved separately from the image data. You can view the unmodi- fied image data at any time by opening the image in Nikon Scan and hiding changes to settings by clicking the check mark at the top left corner of the appropriate tool palette. NEF can be used to scan images at bit depths of twelve or four- teen bits, with settings in the Digital ICE Cubed NEF (Digital ICE3), Analog Gain, and Scanner Extras palettes adjusted before the image is scanned. You can then save the image in NEF format after adjusting brightness, contrast, color balance, and sharpness in the Nikon Scan applet. You can later open the image, undo the changes or make further adjustments as desired, and then save the results in a different format and in a separate file, repeating the process as often as necessary. NEF is supported only in Nikon Scan and Nikon Capture camera control software for Nikon D1 digital cameras. Reference:The Nikon Scan Applet 98
