What it is
{"overview":"The Thornton-Pickard Imperial Triple Extension is a British-made wooden plate field camera, notable for bellows that extend to roughly three times the normal focal length to allow close-focus and long-lens work. Buyers researching what one is worth should note these are saleroom wholesale levels rather than retail asking prices.","buying_guide":"Inspect the bellows carefully for pinholes and corner splits, as replacement is the single most expensive repair on a camera of this age. Check that the triple-extension rack-and-pinion movement runs smoothly front and rear, that the ground glass is intact, and that the lens board, focusing screen and any dark slides are present — missing plate holders sharply reduce usable value.

Questions
What affects the price and value of this camera the most?
Bellows condition, completeness of plate holders and lens, and the state of the wood and brass fittings drive most of the price variation; a camera with light-tight bellows and its original shutter commands a clear premium.
Is the Imperial Triple Extension still usable?
Yes, provided the bellows are sound and plate holders are present, it can still be used with sheet film adapters, which is part of why clean examples hold value rather than trading as pure decoration.
