Dan, while I agree with you in principle I disagree somewhat on this ... as I have before. Like you, I agree that Lefkowitz is the 'horn book' of macro photography ... also doesn't hurt to add "Image Clarity." Unfortunately, IMO 9and again I know you don't agree) I find that far from all of what Lfowitz talks about is sully applicable to LF macrophotography. Beyond that there are even more very specific technical issues that apply only or more usually to LF macro work than to that in other formats.
