The word „Photography” came from the Greek two words: „Phos” φῶς which translates as light and Graphis γραφις which translates as write. Writing can translate literally „drawing with light”.
Since the time of Aristotle was know how reality can be placed in a box: it is enough to make a hole in a box to appear a true reversed image inside the box. This produces a so-called “camera obscura”.
On the other hand, alchemists knew that light darkens silver chloride. A third contribution came from John Herschel, who in 1819 described the sodium hyposulfite property, which will become “fomafix” for pictures.
All photography was originally monochrome, or black-and-white, but, after cuple of years color photography also appeared. Even in our days, with all the modern technology at our fingertips, are enough photographers who like to shoot in black and white
Ted Grant says: “When you photograph people in color, you photograph their clothes. But when you photograph people in Black and white, you photograph their souls!”.
Digital era of photography
In 1991, Kodak unveiled the DCS 100, the first commercially available digital single lens reflex camera. At the time, this was a very expensive camera and few people could afford it.
Digital imaging uses an electronic image sensor to record the image as a set of electronic data. In the case of digital photography is a highly manipulative medium. Digital photography dominates the 21st century. More than 99% of photographs taken around the world are through digital cameras. Also, thanks to smartphones, photography is available to everyone now.
Currently there are three types of digital cameras:
- Compact cameras
- Bridge cameras
- DSLR cameras
Let’s talk a little about them…
- Compact cameras
Are those devices, the most common, small, light, with all sorts of features on them, and the prices is quite low. At this time, such a Nikon or Canon camera say (among the best known brands) of 12-18 MPX costs around 200-500 USD. One of the significant advantages thereof is, in addition to the price sure, is the size. You can take with you anywhere. You put the camera in a pocket and went to “hunt” for images. Battery life is somewhere between 70-200 photos (depends especially if flash is used or not, or it is used for filming).
The main disadvantages are particularly small size of the sensor that forms an actual image and another important disadvantage is that you do not have access to a lot of many settings. And a very useful setting that is absent from most of them (at least currently) is the setting that allows you to adjust the aperture.
- Bridge cameras
Are those devices that can say that is between those compact and DSLR cameras. They’re bigger, have a more powerful lens, a little bigger sensor and access to more settings. Some of them have the ability to save files in RAW format. This type of file can store more information and, after, can be make corrections / adjustments in the computer. Compact cameras do not have such options. Other advantages would be: larger LCD screen with a better resolution, lens which provides a wide focal much higher.
As disadvantages we can mention: their size, which is not so small as compact, so difficult to carry, and does not allow changing lenses, it came standard from the factory with certain characteristics.
- DSLR cameras
This range of equipment is subdivided in 3 sub-categories: entry level, those with a smaller sensor (approx. 22.2 x 14.8mm), middle level, those with may be the same or a larger sensor, more resistant casing, the possibility of more complex settings, etc. and hi end or the full frame sensor with 36 x 24 mm.
In general, the main advantages of DSLR cameras are: size of image sensor which translates into superior quality, the ability to change lens, the ability to attach an external flash for a much higher power, full control of aperture, shutter speed, ISO sensitivity, etc. The images come with a much lower noise, greater life battery (over 500 to 1000 photos ore even more).
Disadvantages I could mention their size that is much bigger than a compact camera and so becomes more difficult to carry, can cause problems during lens exchange, namely the possibility of dust gets on the sensor if not done carefully this operation, and, of course, the higher price.
Our advice is to make a sacrifice for 500-800 $ (or more) in addition to buy a DSLR (at least one second hand) for start. You’ll see that you will not regret it. The difference is very huge. You can start with a compact but have an unpleasant surprise when when you look more closely at your photos. Let the camera do what he knows best, and you use your imagination and technique to be able to reproduce good quality photos.
And another thing: no matter what camera you have, you must necessarily to read the manual! Try to control your camera, not vice versa!
