A single-element camera lens is as long as its focal length; for example, 500 mm-focal-length lens requires 500 mm from the lens to the image plane. A telephoto lens is made physically shorter than its nominal focal length by pairing a front positive imaging cell with a rear magnifying negative cell.
Pictorialism is an international style and aesthetic movement that dominated photography during the later 19th and early 20th centuries. There is no standard definition of the term, but in general it refers to a style in which the photographer has somehow manipulated what would otherwise be a straightforward photograph as a means of creating an image rather than simply recording it.
Together, these announcements caused early commentators to choose 1839 as the year photography was born, or made public.

From 1910 to the early 1930s, the dominant style was East Coast Pictorialism in which objects were shot with haze and gauze to purposely blur the image for a soft focus effect. The aim was to mimic Impressionist paintings. With the emerging West Coast Movement, photography no longer imitated painting and developed as a separate art form.
The earliest known examples of compound microscopes, which combine an objective lens near the specimen with an eyepiece to view a real image, appeared in Europe around 1620. [53] The design is very similar to the telescope and, like that device, its inventor is unknown.
