The width of an image should measure 8" (20.3 cm), but the height may not exceed 6" (15.24 cm). These dimensions are imposed by the measurements and proportions of computer monitors. Image files should be in jpeg (72ppi - quality 8, high) format. Borders of up to 0.5" (1.25 cm) width should generally be added, but the the maximum dimensions of final images must not exceed the limits specified above. Borders arguably improve web-page presentation but inevitably reduce the area occupied by the images themselves. It is recommended that photographers look at current website galleries before adding borders to their images.

Note that images selected for the Society's on-line exhibition may not be displayed at exactly the same size as the submitted image. Monitor resolution, software and other practical matters may influence the dimensions seen on individual computer screens. All submissions should initially be emailed to the Society's submissions office.
