Thats a little harsh.
FoxTalbot was working on his own discoveries from 1835 a sheet of fine writing paper, coated with salt and brushed with a solution of silver nitrate. He found it darkened in the sun, and that a second coating of salt impeded further darkening or fading. Talbot used this discovery to make precise tracings of botanical specimens: he set a pressed leaf or plant on a piece of sensitized paper, covered it with a sheet of glass, and set it in the sun. Wherever the light struck, the paper darkened, but wherever the plant blocked the light, it remained white. He called his new discovery “the art of photogenic drawing.”.
So he experimented with this until in 1839 when the daguerreotype was revealed, at which point he presented his work to the royal society, before Daguerre presented his process.
Can you tell I'm a frequent visitor to Lacock? Usually to the exhibition space to be fair.
