Gamma Gradation definition

Gamma Gradation. This adjusts the gener- al brightness of the image for midtone and shadow. In general, a gamma of 1.6-1.8 is recommended. For transparency, the gamma is normally higher than for reflective (transparency 1.8-2). • Show image after scan: If this option is selected, the finished file will be opened by the finder. (Applicable if “Normal (File)” and “Batch mode (File)” are selected. • Realtime correction: The normally present realtime correction can be turned off here for use with older and slower computers. Special defaults • Halftoning*: Dithering algorithms for scanning halftone images in lineart mode • Colour Filter (blind colour)*: Select the colour, which you wish the scanner to ignore during monochrome scans. You can choose between red, green or blue. • Monochrome Preview: In case there is scan- ning in greyscale or black and white only, you can speed up the prescan considerably by • Prescan Draft*: Faster prescan with reduced quality. • Scan Draft*: For scans with reduced quality. • Limit Gamma Slope: May be checked if much noise is encountered in the shadows. The slope of the gamut curve which is especially steep in the shadows, will then be reduced to an almost linear function. Einleitung Installation von SilverFast

  • Finished grade means the grade upon completion of the fill or excavation.

  • Highest adjacent grade means the highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure.

  • Highest Adjacent Grade (HAG) means the highest natural elevation of the ground surface, prior to construction, immediately next to the proposed walls of the structure.

  • Highest Rating Category means, with respect to a Permitted Investment, that the Permitted Investment is rated by S&P or Moody’s in the highest rating category given by that rating agency for that general category of security. By way of example, the Highest Rating Category for tax exempt municipal debt established by S&P is “A 1+” for debt with a term of one year or less and “AAA” for a term greater than one year, with corresponding ratings by Moody’s of “MIG 1” (for fixed rate) or “VMIG 1” (for variable rate) for three months or less and “Aaa” for greater than three months. If at any time (i) both S&P and Moody’s rate a Permitted Investment and (ii) one of those ratings is below the Highest Rating Category, then such Permitted Investment will, nevertheless, be deemed to be rated in the Highest Rating Category if the lower rating is no more than one rating category below the highest rating category of that rating agency. For example, a Permitted Investment rated “AAA” by S&P and “Aa3” by Moody’s is rated in the Highest Rating Category. If, however, the lower rating is more than one full rating category below the Highest Rating Category of that Rating Agency, then the Permitted Investment will be deemed to be rated below the Highest Rating Category. For example, a Permitted Investment rated “AAA” by S&P and “A1” by Moody’s is not rated in the Highest Rating Category.

  • Rating Category means one of the generic rating categories of any Rating Agency without regard to any refinement or gradation of such rating by a numerical modifier or otherwise.
