I know there is a site that does this. Unfortunately, I don't have an iPhone and there is no wifi hot spots where I shoot most of the time. Anybody know if a standalone version exists for the iPhone/iPod Touch ?
If you take a look at the iPhone page (http://dofmaster.com/iphone.html) it says: Open http://iphone.dofmaster.com on your iPhone or iPod Touch to use the web app.dofmaster.com claims to have one for ipod/itouch.
Lining up the infinity symbol with the aperture markings on my lenses works pretty good, too, by the way.
Both of these are widgets and only work on "real" Mac OS computers. I knew and used the first one and just installed the second one. Funny thing, I don't get the same results on both of them !!!
Someone may beat me to it, but it is in the works.Charles, you're the man !
Let me know if you want me to beta test it !
