Most of the recent cookery books I have bought have very much been of the real food photography, not faked type. Nigel Slater's latest for example (everything he ate for a year, photos tajken before eating), and Dan lepard's baking books. Fashions have changed, though packaging versus cookbooks are rather different. I slightly know a food photographer, who finally went digital recently, but with an MF back - you cant really do food photography without camera movements I dont think, at least for smaller foods.
