According to the invention, there is provided seed and plants of the hybrid corn variety designated CH148845. Microfeature workpieces are electrolytically processed using a first processing fluid, an anode, a second processing fluid, and an anion permeable barrier layer. The system and method corrects for roll-off in image data by determining for each pixel a roll-off contour in which the pixel resides and adjusting that pixel based upon its roll-off contour, which in turn, depends upon its location on the image plane. , network to a remote network upon authorization by a content manager process. During processing of the image, the luminance values of all of the pixels in the second illumination area are restricted from any adjustment.
