The ways to improve the quality of photos

As the saying goes, if you want to do a good job, first you must sharpen your device. Also, to shoot out high quality, canvas prints online pictures, choose to use high quality photographic equipment and film is the primary. Now, camera and lens is extremely wide range, to choose a suitable camera and lens is not an easy thing, but one thing is no doubt about it, that is according to the subject, as far as possible choose picture of a big camera and form a complete set of high quality lens, it's good to get high quality image extremely. As for the film, due to the sensitivity of film and film contrast, tolerance, granularity, resolving power, such as fog degree and save the performance in the inner link, low sensitivity of the film in colour saturation, granularity, like force, fog degree has great superiority in aspects, therefore, selection principle of the film is as far as possible choose low sensitivity of the film.

Accurate exposure: set the shutter speed and aperture size, press the shutter, the light at the instant of the shutter release through the lens and film, which is exposed. Exposure looks be like simple, actually is a very important technical control, not only directly affect the density of the piece, but also to the image color, clarity, particles and hierarchy, etc. Accurate exposure depends on accurate metering, mastering all kinds of metering principle of the meter, and can be taken in a variety of conditions and requirements to make a reasonable metering numerical correction is indispensable to accurately exposure.

Accurate focus: sometimes will meet such embarrassing phenomenon: a film made in small picture, main body quite clear; when magnified into a big canvas art prints pictures in the photo is clear parts fell outside body, the main body is fuzzy. The phenomenon of tend to be caused by inaccurate when shooting focus. In the use of such as 135 small pieces of camera with accurate focus is particularly important. Generally, to achieve accurate focus must pay attention to the following two points: (1) as far as possible use high focusing eyepiece, magnification of images for accurate focus was of great help. (2) When using wide Angle lens to focus carefully, don't think the depth of field of wide-angle lens is great and so. Accurate focusing in the use of telephoto lens, in fact, when it is very easy to do, but it is difficult when using wide Angle lens.

Strictly control the depth of field. Understanding the depth of field control, both of which are necessary to: (1) according to the calculation formula of depth of field, before and after the depth of field is unequal, the depth of field is always greater than the prospect of deep, therefore, in the depth of field control, can't take it for granted to focus on in the middle of the depth of field, in this way, outlook will often not enough. (2) The depth of field in addition to the size of the aperture size, the lens focal length and the distance outside, also related to image allowed by the fuzzy circle diameter, and fuzzy circle diameter with magnification of film and see photos of the size of the distance. In fact, the lens depth of field measure is the magnification of manufacturer set by you and marks, therefore, in the film giant pictures, we want to than with depth of field lens scale more strictly controlled, otherwise, it's easy to have a depth of shallow phenomenon.

Creative light: the light is very important in photography, there are two: one is to make the film; the second is to make the foreground objects produce different shape, color and texture effect, and can control the tone of the image. Creative lighting can make the ordinary extraordinary effect.

New composition of a picture, there is no doubt that the new composition of a picture can make the canvas prints picture fascinating! But in fact, the composition is a personal thing, it is difficult to have good and bad standards, grasp the good composition, need the photographer has the good quality, a famous American photographer Edward weston well said: "good composition is a kind of effective way to observe the subject, can not teach people, like creativity, is a kind of gradually formed the individual qualities."

Ensure exposure when the camera is stable. When the vibration and shaking of the camera will be a fatal impact on image clarity, therefore, to ensure the stability of the camera is very important. Using solid tripod can, through the shutter release the shutter and mirror camera, in the process of the rising pre litre mirror first, then press the shutter and so on all is a very effective way to guarantee the stability of exposure when the camera.

Selects high quality filters. In order to truly reflect and performance have been the object of the original color and level, or to be the object of color, tone and atmosphere of rendering for creative expression, the use of the filter is indispensable. For the selection of filter, the first thing to do is chosen high quality filters. Because, filter like camera, directly related to the image quality. Inferior filter with high quality lenses with is a waste of expensive high-quality lens! Second, does not use filter too much overlap. Much of the overlapping filter can produce diffuse light through the filter, which affects the image sharpness, contrast and color.

Frequently with hood: hood is a small attachment, but has a very important role, can eliminate or weaken the glare, make the image has good clarity, color and contrast, especially when the backlight photography. Therefore, must form the good habit of frequently with hood.
