The Thornton-Pickard Amber (half plate) is a British wood-and-brass field camera taking half-plate glass negatives, a format common in late-Victorian and Edwardian large-format photography. It was sold as a general-purpose plate camera for studio and outdoor use rather than as a top-tier specialist instrument.

Sales evidence for the half-plate Amber is thin: a single UK auction record from February 2025 shows a hammer price of £138 at saleroom level, which is wholesale rather than retail and excludes commissions. With only one data point available in 2026, today's value for a comparable example is best treated as broadly in line with that figure, though condition, completeness of the bellows, and the presence of original lens and plate holders will move what one sells for in either direction.
