I am about to have some pictures taken with my A300 included into a local photographic competition. As per rule, the printed size must be 40 x 30cm edge to edge. The problem i am encountering is that the photo size i got out from my camera are 40.96cm x 27.37cm. I have also added a surrounding border, and then the size is 43.88cm x 30.33cm.
What can i do in order to produce a 40x30cm printed picture? I do not wish to crop the picture as it is nicely composed in my opinion.
