I just had this thought. In the film days many professionals didn't use high end scanning. Some were also using medium format instead. So with a 6x6 or 6x7 medium format film camera using a Epson scanner or just the usual lab's Photo CD how does A3 prints (12x16) compare to say what we have now with digital SLRs or mirrorless ie the 16-25MP range. In regards to 35mm how does it stack up by comparison? I know that when I got my graduation photos done 15yrs ago my photographer who also does weddings, he was still using a 6x7 but now he has gone to dSLR. Cheers.
