Further technical details of the CCCH AT contest for those interested

First: Although HPS and a committee member felt that size should not matter if we state pixel dimension, it appears from Don Brown's steps that there is support for a maximum size limit for the entries. We believe, however, that his 400KB limit is too small for a sharp image. Thus we retained MCC's standard of 1 MB maximum. His steps can be used to ensure the 1 MB size and still be within pixel size dimension limits. (Let Joy know if you want her to give you his step-by-step requirements).

Second: Although the prospectus allows for a maximum size of 1024 pixels at the longest side, there is support for image sharpness fall-off due to the nature of projection such that the maximum 1024 pixel side should not be used. Don Brown recommended 924 pixel, one committee member recommended 1000 pixel.

Third: Although the prospectus does not state ppi size and Don Brown recommended a uniform 104 ppi, one committee member (who scored very high in the midyear image contest) recommended 300 ppi. Please be aware that if your image does not support a 300 ppi (such as images scanned at 72 dpi), you should not use 300 ppi because upsizing a low resolution image will degrade it.

Fourth: The standard projector's 1024x768 pixels projection favors landscape formated images. We felt that it is too late at this time to discuss whether we should require everyone to turn in a square image but are sending out this separate email as a cautionary warning.

Fifth: The specs and other details for InFocus IN26+ projector can be accessed from http://www.infocus.com/Support/Products/Projectors/IN26plus.aspx. Screen: Da-Lite Keystone Eliminator 60x60. We intend to color balance the projector prior to the final competition.
