Early cameras of the sixteenth and 17th century had been capable of undertaking pictures onto paper or glass but the study of capturing, processing and printing the images took many more years. The know-how in these cameras has come to date that they will outperform some of the digital single lens reflex cameras of years previous. The invention made in 1851 by Frederick Scott Archer was a blessing for the reason that new methodology termed the Collodion course of called for simply 2-three seconds of light exposure to seize an image.
