A mass spectrometer is disclosed comprising a quadrupole rod set ion trap wherein a potential field is created at the exit of the ion trap which decreases with increasing radius in one radial direction. The method includes producing shifted error signals for each color channel, weighting the shifted error signals to determine weighted error signals for nearby pixels that have yet to be processed; producing shifted weighted error signals; and adjusting the input levels for the nearby pixels responsive to the shifted weighted error signals. Each micro-template may correspond to a particular synthesis operation and may be enabled or disabled. The information is to be sent to an entity that is different from an entity that substantially controls or owns the electronic site and different from an Internet service provider of the user, if the user is to use the Internet service provider in accessing the electronic site. The mask pattern is applied to an associated flash head so that an exposure of the composition is made with the masked flash.
