My Photographic Beginnings The first camera that I owned was a Kodak Brownie that was a present given to me by my brother Jim when I was about ten years old. I used the camera for family photographs but not for "serious" photographs and very few images survive that were taken on this camera. This was replaced a few years later by another camera It also and had an accessory shoe and sync socket allowing use of a flash unit.
Lens types and effects[ edit ] Focal length[ edit ] How focal length affects perspective: Varying focal lengths at identical field size achieved by different camera-subject distances.
Notice that the shorter the focal length and the larger the angle of view, perspective distortion and size differences increase. Lenses are often referred to by terms that express their angle of view: A circular fisheye lens as opposed to a full-frame fisheye is an example of a lens where the angle of coverage is less than the angle of view.
The image projected onto the film is circular because the diameter of the image projected is narrower than that needed to cover the widest portion of the film. Characteristics[ edit ] For a given camera—subject distance, longer lenses magnify the subject more.
For a given subject magnification and thus different camera—subject distanceslonger lenses appear to compress distance; wider lenses appear to expand the distance between objects.
Another result of using a wide angle lens is a greater apparent perspective distortion when the camera is not aligned perpendicularly to the subject: For example, buildings appear to be falling backwards much more severely when the camera is pointed upward from ground level than they would if photographed with a normal lens at the same distance from the subject, because more of the subject building is visible in the wide-angle shot.
Because different lenses generally require a different camera—subject distance to preserve the size of a subject, changing the angle of view can indirectly distort perspective, changing the apparent relative size of the subject and foreground.
If the subject image size remains the same, then at any given aperture all lenses, wide angle and long lenses, will give the same depth of field.Reach the right respondents.

For nearly two and a half years, Sony had the 1"-type sensor compact camera segment all to itself with its RX series.
While Canon had its PowerShot G1 X (and the Mark II that followed), they were anything but pocketable. A. Aboriginal Rock Art Usually refers to Australian rock painting and petroglyphs. Abstract art Ill-defined and very widely used term which in its most general sense describes any art in which form and colour are stressed at the expense, or in the absence of, a representational image.
