Dis advantage and advantage of folding roll film camera
Answers
Answer:
Advantages:
Film images can be more archival than digital ones (unless the digital ones are printed). In the case of B&W vs color, B&W images are even more archival than color ones.
If you’re shooting slide film, and you’ve got a projector, you can project the images really big. Like side of the garage big.
Film can be really high resolution, especially when you’re shooting large format or low ISO film.
If the camera is mechanical, you need no batteries or electricity to be able to take a photograph.
Disadvantages:
Unless you’re using sheet film, you cannot vary the sensitivity from shot-to-shot.
You have to finish the roll of film before you get to see any of the photographs.
Higher ISO films have bigger grain, and thus smaller resolution. The fastest film made is Delta 3200, which is around ISO 1250, but has a box speed of 3200. My 10-year-old Pentax K-x goes from ISO 200 to ISO 12800. Sure, I can take that Delta 3200 and expose it at ISO 6400, or even ISO 12800, but the DSLR images will look superior in low light at high ISO when compared to film.
Generally speaking, the results of the digital camera are viewable immediately, as opposed to having to wait until the roll is finished, and then develop them (and print, in the case where you’re not shooting slide film).
With modern infrastructure such as the Internet and Facebook, it’s easy to share digital images around the world. With film, you either have to convert it to a digital image with a scanner (or digital camera), or you have to physically transport the image from one location to another. It’s far faster to send information in the form of energy (1s and 0s) than it is to send a physical object like a slide or photographic print.
Answer:
A folding camera is an camera type. Folding camera fold into a compact and rugged packages for storage. The lens and shutter are attached to a lens-board which is connected to a body of the camera by a light-tight folding below. When the camera is fully unfolded it provide the correct focus distances from the film. The key advantage of folding cameras is that their excellent physical-size to film-size ratio when the camera is folded for the storage.
Portable folding cameras dominates camera design from the 1890s to 1930s and were significant into late 1940s. Specialized cameras such as Polaroid SX-70 Instant film camera, and the Speed Graphic press cameras used folding designs into 1970s.
The typical amateur camera of the early 20th Century made a lot various "postcard" sized negative around 4" × 5". By the 1930 6 cm × 9 cm cameras for either the 120 and 620 film size, were highly popular.
The use of folding cameras declined in late 1930s with advances in lens technology allowing superior enlarged, high quality images on smaller negative, and shorter distance between the lens and the film. 35mm film made small-sized camera practical without using bellow. Lens technology allowed 120by620 cameras to use shorter focal distances, and the twin lens reflex cameras became popular. However, some 35mm camera continued to be built as folding cameras, for e.g., the original Kodak Retina and the Ensign Midget model 22 cameras (image at lower right). Medium format folders were produced in USSR until the 1960.
