Digital-Film Camera Differences

Powering the camera:

Film: Takes disposable batteries that require infrequent replacement.

Digital: Takes one or more of a variety of battery types--both disposable and rechargeable--that require frequent replacement or recharging.


Recording pictures:

Film: Uses film, which comes in various frame sizes and different sensitivities to light.

Digital: Uses a fixed, light-sensitive, silicon chip that comes in two varieties: CCD or CMOS. This chip determines the frame size and the light sensitivity of the camera. You can simulate the effects of using different types of film via settings within the camera.

Framing shots:

Film: Uses an optical viewfinder that shows 97 to 100 percent of the scene.

Digital: Uses an optical viewfinder, as well as an LCD that displays 100 percent of the scene. But an LCD can be hard to see in bright light and uses a lot of battery power. Many cameras substitute the optical viewfinder with the kind of electronic viewfinder (EVF) that is used on camcorders. Photographers who are used to optical viewfinders don't always like EVFs, so try before you buy.

Snapping shots:

Film: Instantaneous capture.

Digital: Varies wildly, depending upon image size, file format, media type, memory available for temporary storage, sensor type, and speed of autofocus

Storing pictures:

Film: Stores images directly on the capture medium (film), which is single-use and supplies a fixed number of frames per roll.

Digital: Stores images as digital files on reusable memory cards or discs, both of which come in various capacities and can hold a variable number of frames per card.


JPEG
Small and fast for capture but has file compression that may introduce artifacts that degrade image quality.

RAW
Smaller than TIFFs and more flexible for postcapture retouching. Not offered on all cameras, and special software is required to read them.

TIFF
Large files that can slow down your shooting and fill up your media but have no compression artifacts.

history of photography-Pinhole cameras

Pinhole cameras - remember them? You might have made one in science class. Punch a hole in an oatmeal cereal can, put film inside, uncover the hole momentarily, and then develop the film.


Pinholes have been in use a long time, originating as perspective viewing devices as far back as 1425 by Filippo Brunelleschi. Camera obscuras, based on the pinhole principle, were built - one example exists in Edinburgh, Scotland in a tower on the Royal Mile below the Castle. Some of the first pinhole photographs were made by Sir David Brewster in 1859. By the early 1900s, pinhole photographs were again relegated to the dustbin of history, with lensed cameras overtaking the pinhole in convenience and speed. Kodak briefly made a commercial pinhole camera in the 1940s. Pinhole photography today remains primarily an artistic medium enjoyed by a dedicated group of photographers, and several web sites provide rich information on pinhole photography techniques. It´s all nice and fine How to Make a Pinhole Camera


okay ok... come to the present


Zero Image is a Hong Kong based company, producing a range of beautifully designed and finished pinhole cameras in a variety of formats, all of which we are stocking. All the cameras are made with exceptional attention to detail in selected high-quality teak wood. More than 15 layers of coating is applied by hand to each camera, to insure maximum protection of the wood. The metal parts are hand-turned, solid brass.
A coating is applied to all of the brass parts to prevent them from oxidizing. All are gloss varnished with brass fittings, and supplied with a certificate showing edition number.Brass shim of 0.001" is used for pinhole construction, making the pinhole conform to a more accurate film stop number and yield sharper images.
