Technology of Photography

1) What are some photographic effects that can be achieved using digital or analog (darkroom, film, light etc) technology?

Both digital and analog technology can change the colour, texture, luminosity and image size. They can also change the content of the photo like the shape of the object.


2) What are some photographic techniques that can only be done using digital technology?

(a) Analog technology cannot provide a immediate accomodation for photo effects. Photographers can only assume the effects in virtue of their professional and experience. The result is always seen when the image processing is finished. Digital technology allows an immediate preview and delete in order to anticipate and achieve the most delightful effects.

(b) Certain amendment of analog technology on the photo cannot be restored while digital can.


3) What is the difference between analog photography and digital photography?

(a) The limitation of alteration of the two technology is different. Analog technology can just alter on a primary level. For instance, it can partly or totally change the colour or the texture in a very rough manner. It cannot go deep into minute amendment. The individual using digital technology can arbitrarily fuse parts of the images together, add abundant effects onto the photo, and therefore generailize a fresh new image.

(b) Various equipments and tools are necessary to implement analog technology. However, digital technology just needs a digital camera, a computer and a proper software to make photographic effects.
