Tilt–Shift Photography involves various camera movements Tilt and Shift movements of the lens or the mount of lens. It has usages like for Miniature Faking. Basically, the functions ‘Tilt’ and ‘Shift’ are independent, so there are lenses that allow for example, only shift and there are professional cameras in which the function tilt and shift through is not implemented through mechanics of the lens itself, but by the camera alone.…
Lens speed means the maximum aperture diameter a particular lens can have. As the f-number is reverse, it becomes the minimum f-number of a photographic lens. As usually we mention f-number, e.g. like 1/2 or f /2.8 (2.8 is the f-number and f is the focal length); manufactures mark the lens with this digit. This diameter is named as Lens Speed as the Light intensity of incident rays through a lens with the quotient of the maximum possible diameter of the entrance pupil when focal length of a lens is constant, becomes proportional to the shutter speed. In other words, higher the aperture will be, less exposure time will be required with a faster shutter speed, which obviously is a big advantage.…

We are not going to discuss the elementary chapters on Portrait Photography taking that the reader is already used to these topics either by reading our or and standard blog or book. Today, most of the good Authors of Digital Photography tips providing blogs becomes the Author of standard printed Books from good publishers. So, practically choosing a good book and Author’s active Photography Tips blog is very important; you can directly communicate citing his/her book.…
Aspherical Lens in Digital Photography is designed to correct the aberrations produced by the usual spherical and optically differs from the spherical shape. Previously we discussed about Chromatic Aberration. If you think about the Photographic Lens Design, it will be apparent that; more complex the lens design is; more complex the spherical and other aberrations will be. Spherical aberration is not in case of lens, but for the mirror of DSLR too. The basic physics is that, due to the increased refraction of light rays like the prism; light rays when they strike a mirror near the edge, it results in an imperfection of the produced image. In case of mirror this is corrected for our eyes by using a bigger sized mirror or by using a specially coated mirror. As Lens is the set of element which will basically determine the quality of image with a given image sensor; Asperical Lens becomes an important element …
Reflector in used both in photography and cinematography, the basic idea is to lighten the subjects with indirect diffused soft light to control the appearance. Appearance of what ? Appearance of the details of the subjects. For example, when the sun is over our head, if you take a picture without using reflector / reflectors / external extra artificial light source; the shadow casting on the faces will remove the details of the face – this is the basic reason why we use Fill Flash in Digital Photography and Film Photography.…

Telephoto Lens in Digital Photography are mainly intended for DSLR and with respect to a standard lens, has long focal length and a smaller angle of view. From technical or optical aspect, telephoto lens is kind of lens which extends the light path to optically emulate a typical long-focus lens with a much small overall design.…
