What is the full frame digital SLR camera?

Full-Frame DSLR camera, is a very popular word recently in the Digital Camera Marketing. So how do you understand the full frame concept? Full-frame digital SLR camera, It means that the size of D-SLR Camera’s sensor is same size with the traditional 35mm film (36x24mm) camera. Yet, No-full-frame digital SLR’s sensor is smaller than traditional 35mm film camera , such as the common APS-C size camera, its image sensor size is about 22x15mm.

What good the Full-frame digital SLR has?

First, Because the full frame digital SLR’s sensor size is large , that means the same pixel, pixel area is large in a single sensor, the large pixel area will bring a better photographic performance, showing less the noise, wider dynamic range and so on. Let us look at an example: Nikon D3 and Nikon D300 were released, They are both with EXPEED image processing engine, But the D3 with full frame CMOS sensor its sensitivity up to ISO 25600, D300 with the APS-C size CMOS sensor , Its highest sensitivity is ISO 6400. Secondly, the digital SLR Camera with full frame sensor is as large as the traditional 35mm film camera, that means there is no focal length conversion factor. the full frame digital SLR mount a A 24-70mm lens, the focal length is still 24-70mm, covering wide-angle and telephoto-angle, and if a normal digital SLR mount a A 24-70mm lens, the focal length becomes 38-112mm, and its wide-angle is reduced.

However, full frame digital SLR Camera have some inevitable drawbacks. One is the high price. such as Canon EOS 5D that was release before three years, But Now its price still above $2500. Second, full-frame digital SLR camera also need a better quality requirements of lens. for example,Canon EOS 5D and 1D, only the high prices or the fixed focal Lens can give full play to the strength of full-frame digital SLR, otherwise, full frame digital SLR camera will expose some weaknesses of lens, such as vignetting, chromatic dispersion and the fall in the edge of resolution. Therefore, if consumers buy a full frame digital SLR Camera, the lens will spend a lot of money.

photography composition tips for Digital Camera

Composition mean modelling art, in drawing theory, also called the “layout, the composition is all of the plastic arts important modelling meanses.

For a long time, and painters after serious research to find some art is universally useful composition rules. The digital camera after the invention, these composition rules were also photographers to use. Photographic composition generally speaking, it is to show the theme, and photographs to screen people or things and other things, foil environment make appropriate arrangements, and use artistic means to strengthen or weaken some parts of the picture, finally, to make the subject is prominent, the subject and foil between body of layout unification, picture density have diversiform, and structural balance of artistic effect, make the theme thought fully, perfect performance.

Photographers are sometimes will graphics or object is put in particular position again after the photography, this is the so-called put filming. But in most cases was filmed things cannot allow you to display the, at this moment need to change the camera Angle to change composition, but the camera on subtle move, can produce strong in composition of change.
