Technical Question : We are asked to submit our images at 72 dpi ! Not knowing what this means, I asked an expert to convert my images to this.
He came back with the following answer : presently your images are at 96 dpi, to change them to 72 dpi does not make any difference. Perhaps they need to be set to A5 size at 72 dpi or maybe 1000 pixel long edge at 72 dpi.
please can anyone answer this question, obviously applying to any gallery or competition , I would like to do this in the right way.
