Tech Post #4: DSLR Summary and Analysis

Cameras have come a long way ever since they were invented. The first camera to ever exist was the Pinhole Camera (also known as the camera obscura) which was invented in 1827 (Balihar, 2011, para. 1). Soon after, the daguerreotype emerged in the 1839 which was the first camera to be able to maintain an image without having the image disappearing (Lidsay, 2011, para. 4). In 1975, digital cameras were invented and to this day people still use them (Bose, 2011, para. 2). Even though digital cameras are constantly being used these days, in 2005 DSLRs were becoming more popular (Roberts, 2011, para. 7).

The different generations of cameras draw on ideas of its precedent’s aspects. The first Pinhole Camera absorbed light in order to take a certain photograph. Although the image didn’t last long, the image was still taken (Balihar, 2011, para. 1). The daguerreotype also drew light in in order to produce a picture. The difference between the pinhole camera and the daguerreotype is that the daguerreotype can store the pictures permanently (Zhang, 2011, para.2). The digital camera contains everything that the daguerreotype has. However, the digital camera is portable, light, and stores images quickly in a digital way. Also, the images are in colour and there are basic options such as changing white balance and ISO settings (Roberts, 2011, para. 8). Also, digital cameras can film which is the next stage for cameras. The previous generations of cameras were not capable of doing this. The DSLR contains everything that the digital camera has. However, it is faster and better in all ways (besides the lighter aspect). Like all of its precedents, it draws in light in order to capture an image. In other words, the technologies of cameras draw on principles of its precedents and improve them. For example, the DSLR captures photos like all the other cameras, but it can do it in less than a second. Moreover, the image is saved and would not disappear unless your delete it.

I believe that the next thing that will be incorporated into cameras would be that that live view screen would be touch screen. Also, for more advanced users, the camera parts (such as the body, viewfinder, etc.) would be customizable rather than just the lens. The reason I believe this will happen because more and more electronic devices are beginning to use touch screen (monitors, phones, compters, etc.). Thus, it would make sense if a camera would end up with that function because precision is quite important in photography and possibly film. The reason why I believe that the whole camera might be customizable is because people generally like customizing the parts of their electronic devices. If companies introduced this, it would mean they can possibly make more money.

I believe that the people would love these new camera functions. More and more consumers are beginning to like touch screen rather than a physical item with buttons. For example, many people prefer the Apple products because they are mostly (if not all) touch screen devices. As for the customizable aspect, consumers would also love this feature because they would probably prefer the freedom of changing the pieces of their camera. If they decide not to change the pieces, they can just keep the pieces they already have. In other words, they can just treat it like a modern DSLR camera so there is really nothing that they can get mad about.
