Undoubtedly, out of the numerous iPhone applications, the camera icon/button/application is the most interesting of all. Since the time mobile phones were invented, the ability to photograph real world moments and storing it for eternity has always captured the imagination of humans. This resulted in the iPhone developers creating various special applications for taking photos, the Camera.
Evolution
The iPhone and iPhone3G were the initial versions of iPhone. These consisted of two megapixel camera which is a really good resolution. But these two versions had no capability to record videos. Then came along, the iPhone3GS that has a camera resolution of three megapixels to help you store finer memories to last a lifetime. Videos can be recorded at a resolution of 30 frames per second (VGA). It is not a great resolution, but considering the memory constraints, it is reasonable.
Current Features
Then iPhone enters the market that has a specialized mobile operating system, the iOS4. The iPhone has two cameras, one on the back and one on the front. This is called the facetime feature of iPhone4. One can toggle between these two camera modes with the use of a single touch. The camera at the back has a resolution of five megapixels and the front has a VGA resolution (0.3 megapixel). Also included is an LED flash that helps in the times of bad lighting. The incredible feature of this iPhone application version is the 5x zoom option. The recording of videos is also done in High Definition (HD) with a resolution of 720 pixels and the same 30 frames per second. The front side camera has a lesser VGA resolution of the same frame frequency. It probably sounds like the ultimate gadget to have but there is more to it with the introduction of iOS5, an advanced mobile operating system. This OS has the camera application with enhanced features like photo composition with grid lines, autofocus and auto exposure. It may be just a phone, but Apple does not like to leave any stone unturned even in its camera application.
Usage
This iPhone application opens when clicked on the camera icon in the unlocked screen. In iOS5, this icon appears on the locked screen itself, for faster access to this application. Once inside, instantly we come to the camera mode. On the bottom-left corner is the icon to go to the photo-mode and on the top-left is the button to come back to the camera mode. While in the photo mode, we have numerous options for the currently selected photo, like email, delete, MMS, use as wallpaper or save it up for one of the contacts. These options don't end here since iPhone developers are constantly reinventing and developing newer and better versions all the time.
Review
This feature of the iPhone is indeed commendable for its futuristic technology and ease of use. It is notably easy to handle, even by a layman who knows nothing about technology. Such is the extent of the people-understanding of the iPhone developers that they have designed this wonderful camera application and is complete unique to the iPhone.
