Implementation of color images was hindered by the restricted sensitivity of early photographic supplies, which had been largely sensitive to blue, only barely delicate to green, and just about insensitive to pink. The discovery of dye sensitization by photochemist Hermann Vogel in 1873 all of a sudden made it possible to add sensitivity to green, yellow and even purple. Improved color sensitizers and ongoing improvements within the overall sensitivity of emulsions steadily lowered the once-prohibitive long exposure times required for shade, bringing it ever closer to commercial viability. Around the year 1800, British inventor Thomas Wedgwood made the first known try and seize the image in a camera obscura by means of a light-sensitive substance. He used paper or white leather treated with silver nitrate. Leonardo da Vinci mentions pure camerae obscurae which might be fashioned by dark caves on the edge of a sunlit valley.
