Forum members at www.pentaxforums.com plan to shoot locally on that day and submit images to a central website. Named “PENTAX WORLD DAY,” the global shoot is not intended as a competition (there are no prizes), and it is organized just for the satisfaction of shooting and sharing images with other forum members.
Images must be captured on PENTAX Day (April 5, 2008) between midnight and midnight. Photographers may submit up to three photos. Photos must be taken with a PENTAX camera and should be between 800 and 850 pixels wide or tall, depending on orientation. Photos may be no larger than one megabyte in size. Please leave all EXIF information intact. Images may be submitted from 4/5/2008 to 4/19/2008. After this period, only viewing will be allowed for this category.
