It is a male. You would probably have to dissect the abdomen, macerate it and photo it from various angles. In other words what I do to make a line drawing. Recently in Zootaxa there are some anthomyiid taxonomy papers, where the usual line drawings are now replaced with photographs taken with some complicated equipment and software probably similar to yours. If you send me your email address by private message and I will send you as an attachment an example of this technique.

I would add that a photo of the apical half of the abdomen of a male anthomyiid taken from below (ventral view) would enable a lot of photos to be identified to genera. Unfortunately one can't do this with live flies.
