I recently upgraded from a D50 to a D90, and want to use it for some photomicroscopy. Unfortunately my microscope is an old professional model and an awkward design - fairly high with a vertical camera tube - which would make it very difficult to use live view and a pain to use the viewfinder. This was easy with my film SLR, an old Canon F1 which had a rotating 90-degree sports finder, but a pain with a body that only has an eye-level viewfinder and a screen on the back. When I've tried it in the past it's taken a long time to set up each shot using an angled periscope thingy and get a good result.
What I was hoping to use was some sort of tethering software so that I could do it with liveview, one of the reasons I went for a D90. Unfortunately it would have to be with my laptop, a MacBook Pro running the current release of OS-X, since the microscope is in another room to my Windows PC and I don't have room to set it up nearby. I say unfortunately because I have a good freeware tethering program for the PC, DigiCamControl, but can't find something that works properly for the mac. So far the closest is Sofortbild, but for some reason liveview isn't working, I have no idea why.
I really don't want to spend money on the Nikon software for this, it isn't really a very important project, just a favour for someone.
Any suggestions?
