As a scene-painter, De Loutherbourg was decidedly an innovator and reformer. He was the first to use set-scenes, and what are technically known as 'raking pieces.' Before his time the back scene was invariably one large 'flat' of strained canvas extending the whole breadth and height of the stage. He also invented transparent scenes, introducing representations of moonlight, sunshine, fire, volcanoes, etc., and effects of colour by means of silk screens of various hues, placed before the foot and side lights. He was the first to represent mists, by suspending gauzes between the scene and the audience. He made something of a mystery of the artifices he had recourse to, was careful to leave behind him at the theatre no paper or designs likely to reveal his plans, and declined to inform any one beforehand as to the nature of the illusions he desired to produce. He secretly held small cards in his hand which he now and then consulted to refresh his recollection, as his assistants carried out his instructions. After Garrick had quitted the stage (in 1776) and sold his share in the management of Drury Lane to Sheridan and his partners, it was proposed to De Loutherbourg to continue in his office of chief scene-painter, his salary being reduced one half. This illiberal scale of remuneration the artist indignantly declined, and forthwith left the theatre. He is said, however, by Parke in his _Musical Memoirs_, to have painted the scenes for the successful burletta of _The Camp_, produced by Sheridan, at Drury Lane, in 1778.[17] But he now devoted himself more exclusively to the production of easel-pictures. He had, in 1773, become a contributor to the Exhibition of the Royal Academy. In 1780 he was elected an Associate; in the following year he arrived at the full honours of academicianship. Peter Pindar, in his 'Lyrical Odes to the Royal Academicians for 1782,' finds a place for De Loutherbourg. Having denounced the unlikeness of Mason Chamberlin's portraits, he satirizes the style of art of the landscape painter:-- 'And Loutherbourg, when Heaven so wills, To make brass skies and golden hills, With marble bullocks in glass pastures grazing: Thy reputation too will rise, And people gaping with surprise, Cry "Monsieur Loutherbourg is most amazing!"' [17] Mr. Puff in the _Critic_, giving a specimen of 'the puff direct' in regard to a new play, says: 'As to the scenery, the miraculous powers of Mr. De Loutherbourg are universally acknowledged. In short, we are at a loss which to admire most, the unrivalled genius of the author, the great attention and liberality of the managers, the wonderful abilities of the painter, or the incredible exertions of all the performers.' And in another ode he derides the artist's pictures as 'tea-boards,' 'varnished waiters,' and avows that his rocks are 'paste-board,' while his trees resemble 'brass wigs,' and his fleecy flocks 'mops.'
