Yes, Flats are taken with the same optical settings as the lights i.e. same focus, camera rotation, etc. My question is, can this be accomplished in the Infinity software. The thing about flats, you can't just use any exposure. From what I've read, you need to pay attention to the histogram, which will guide you to the correct exposure length. Not sure how this could be done in Infinity. I'll need to research this more...
