He had studied biology and physiology while at Oxford, but after a short experience at St. Thomas's Hospital he gave up medicine for the law.
He was called to the Bar by Lincoln's Inn in 1882, and joined the Northern Circuit where he acquired a good practice as a junior both on circuit and in London He was junior to Sir Henry James, afterwards Lord James of Hereford, in the case of Ebrard v.

Ferguson had long taken an interest in the scientific side of photography, and in 1900 was elected to a Fellowship of the Royal Photographic Society, in which year he brought out his paper on copper toning, Having made the acquaintance of V. C. Driffield, he was naturally much interested in the work of that scientist and his partner, Hurter, and during his residence abroad he did much research worth with Mr. B. E. Howard, F.R.P.S., on their lines, and as a result thereof his and Mr. Howard's first published work was a paper on "Control of the Development Factor at Various Temperatures," read before the the Royal Photographic Society in 1905. The next year followed a paper on "A New Method of Calculating the Times of Development at Various Temperatures," which was the foundation of the system of time and temperature development now so widely known and used. Kodak, Limited, were the first to take it up, and other manufacturers followed in due course. Among his many inventions for the measurement of photographic densities, the F.R.B. photometer is now used by Ilford, Limited, a she standard instrument.
