Why Photographs Work is now out and orderable from the major online booksellers and instore at real ones too. It's gathering excellent reviews so apparently we're not the only ones who think it's a beautiful book. We're scrambling to arrange a reprint asap.
Mark Dubovoy had written an article for Luminous Landscape promoting the use of medium format. I don't disagree with what Mark says, but I do think there are some points that are important to make.
Pros use medium format because:
1) they often are asked to make huge prints
2) paying customers like to get noseprints on detailed lanscape pictures
3) the equipment is tax deductable
4) the equipment differentiates them from the masses - an important marketing tool (as opposed to an ego boost - pros are too busy for that nonsense)
And there are other reasons. Those of us who do photography for the love of it instead of putting food on the table can afford the time to stitch and blend our way to good photographs, and if the images look better at 13X19 than 40X60, who cares. That said, more than a few serious amateurs are going to be looking at the Pentax 645D.
One of the most useful and powerful tools for doing landscape and industrial photography is live view - totally absent from medium format. Mark talks of the problems of camera misalignment, yet he has to squint into a tiny ground glass if he wants to focus and tilt - while I simply move the magnified view to the corner and check the focus on the sensor, not a substitute - using live view. I think in a few years people will find it hard to believe people ever struggled with substitutes.
We live in interesting times - DPReview has rated the Pentax K5 as the top medium priced dSLR, topping both Nikon and Canon - we live in interesting times.
It's holiday season, Christmas for some of us. May you all thrive and find the images you want.
