Nikon 4 user manual Scale/File Size

Image Adjustment

Keep the output size: Locks output dimensions and file size at their current values, set- ting the aspect ratio of the current crop according to the dimensions input in the Size/ Resolution palette. This height-width aspect ratio will be maintained when you adjust the size of the crop in the active window, and scale will be adjusted to reflect changes to the size of the crop (scale can not be increased beyond 200%). If the image can not be output at the current resolution using the new dimensions, resolution will automatically be adjusted to an appropriate value. This option is useful when you want to set the output dimensions and file size of the final image before selecting a crop.

Width/Height: The output dimensions for the current crop can be entered in these text boxes. The units used to describe output dimensions can be chosen from the menu to the right of the text boxes.

at: The at text box is where you enter the output resolution. This text box is not active if the unit chosen for output size is “pix- els,” when resolution is fixed at 300 ppi. The value chosen at other settings should reflect the resolution of the output device on which the final image is to be printed. The units for resolution can be selected from the resolution menu, which offers a choice of pixels per inch (ppi) or pixels per centimeter (ppcm). The default resolution is 300 ppi.

3 Confirm the final size

To view the final size of the image in pixels, select Show Image Size from the Image menu. The Image Size dialog shows the size of the original (input) image in pixels; if the output size has been changed, the dialog will also list the final (output) size of the image in pixels.

Scale/File Size

Scale (output size as a percentage of input size, maximum 200%) is displayed at the bottom of the Size/Resolution palette, together with the uncompressed file size of the image that would be created at current settings. File size depends on the color model (RGB or CMYK) and, in the case of RGB images, on the pixel bit-depth that will be used when the image is saved. Separate uncompressed file sizes are shown for CMYK and for eight-bit and sixteen-bit RGB.
