Who defined heliography as spontaneously reproducing the image received in the camera obscura by the action of light with all the gradations from black to white?

Joseph Nicephore Niepce is the answer to this question. He is better known as Nicéphore Niépce. He is a French inventor who is best known for inventing photography. He is considered to have started the way that people started to appreciate photography. He did a lot of trials before he was able to make a photograph. There was a time when other countries were not too open about the idea of having cameras and taking photos.

They sometimes believe that this will have the ability to take their soul so this is not really something that they wanted at that time. As time went by, photographs became widely accepted. People love capturing different moments with the use of photographs at this point in time.
