Dear fellow mono-ers, A recent trip to Prague during which I visited several very interesting photographic exhibitions left me thinking that the only way to capture the mood of this fine city is to shoot it in B&W/mono, on film. The visit to the Kafka exhibition was the deciding factor.. So now I have a dilemma: I'm hauling my Bronica ETRSi over there at Xmas to do exactly that, but as I also visit several times a year with a digital camera, is it best to shoot in colour and convert to mono on the desktop, or use the camera's (Nikon D200) own in-built mono mode? What do I gain or lose by not doing so? FYI I use Irfanview to post-process my images: it does almost everything I need and is free, so no PhotoShop answers please TIA!
