I recently bought a 60mm macro and spent a little time shooting some spiders and small flowers. I've been finding the shallow DOF, makes it difficult to get things in focus. I'd like to introduce flash and shoot with a smaller aperture, giving me more DOF. I've briefly seen some home-job softboxes and I'd like to create something myself. I have the attach-on flash that comes with the EM5 and a fl-600r. Any suggestions on what to do?
