There is a picture of mesquite wood (native to mexico, south america, the southwest united states) used in a 4x5 camera I built in the non-gallery pictures section. It is on the second page of photos now. This is a dense wood which finishes easily, is stable and takes fasteners well.
I would avoid poplar, as it is rather soft and does not hold fasteners as well as some other hard woods. On the plus side, it does finish well and takes a stain to look like many other woods with proper finishing.
Cherry, south american mahogany (not asian or phillipine mahogany), ebony, black walnut, ash, hickory, pecan. There are plenty to choose from, but none of them take pictures very well.
