Talk to your local hardwood supplier or find someone locally that builds fine furniture (not just furniture)-- the term you'll be wanting to discuss is "move" as in "how much will the wood move"? Defines how much it expands and contracts under humidity, etc. Its of concern to fine furniture makers in that gaps open up between boards (even with gluing) and warpage occurs.
Also, how the wood is sawed from the log is critical.
And you will want wood that is aged for some time, rather than "fresh wood".
While many cameras are made of walnut, it "moves" a lot but not as much as pine. If you tend to have wide swings in humidity or are headed for the tropics, you might want to choose a more appropriate wood. (Mahogony or ironwood both "move" very little). Ironwood is the wood that moves the least, but good luck machining this wood -its hard as iron (plus dust is poisonous).
