How to make the standard lens?

Canon EF50mmF1.2LUSM

standard lens is a photographic image of the diagonal length of the close focus distance of the lens. Diagonal length of the camera 135 is 43.2 MM, so we generally close around the lens focus distance is called the standard 50MM lens. 50MM lens picture angle of 46 degrees, close to the human eye.

standard lens is characterized by a description of the pictures gives a natural feeling.

as the standard lens is going to get us to see no exaggeration, to describe the natural lens, so the pursuit of true representation of the object photography words are most appropriate to the. Of shoot flowers, landscapes and other documentary photography, the standard lens is the most suitable lens. So since we are easy to understand closeup, macro photography, rings, and so is the standard lens-based reasoning has evolved.

standard lens on the lens is relatively simple form, about virtual taste of the difference between income on the residual method of characteristics to make it easier, so we can see that the header has the unique virtual beauty.

standard lens feature is a natural sense of distance and beautiful description of the virtual taste. Blur is a clear description of the subject as by the core (central part) to the effect. Virtual open heart is the naked eye can not see, can only be seen through the lens photography world. Because of this point, the contours of the virtual object description to give the viewer a better mood stimulation, so feel the U.S. presence. So people spend on film and women in close-up photography, etc., to the header of this feature used to create a romantic atmosphere means of expression.

virtual in effect when the composition also has omitted function. When the subject emphasizing the theme of weakening prospects, after the virtual scene can reflect the performance results. Can be lifted under the nominal theme of the subject, before weakening into the screen view to highlight the fun center. When the subject behind the colorful things, there will be the theme of weakening, then the blur is the most effective.

When F1.4, F1.8 and other large-diameter lens aperture value in the open near the depth of field on a very small, it is easy to be more large blur effects.

How to make good use of wide-angle lens

for 135 systems, wide-angle lens means the lens focus 50MM distance below lens, like the 35MM, 28MM, 20MM, the shorter the focal distance of the more extensive the shooting scene. If it is not limited in space taken place, then stretched shooting distance course without any problems. But if space restrictions on the activities of the photographer when relatively large, it is necessary to use the picture angle is large wide-angle lens. Scenery from the observatory as the whole picture should shoot into the screen, in a small group of commemorative photos shot indoors, the wide-angle lens is particularly effective.

When using wide-angle lens, viewfinder magnification by the portrait small powerful, subtle part of the subject is very difficult to observe, so we must carefully observe every corner of the screen, be careful not to impede the screen shot into things, sometimes prone to photo shoot after a cigarette butt found in the picture and other debris prevent the embarrassment of the screen thing.

wide-angle lens from the description of features, the most typical when is a strong sense of near and far. Focus distance, the shorter the distance to emphasize the sense of the screen, away from the more recent show, the greater the subject. This feature can be described using a wide range of intake screen, when the theme of the subject as a close-range on the screen, the strong sense of distance will have a moving impact. But can not be overlooked is the time to emphasize a sense of distance, in-kind will be deformed, so as a subject of great importance to record the record form is not suitable for photography with this lens. Skewed picture of the seats by the camera great impact, so try not to use overhead, horizontal camera mode can reduce the occurrence of skew.

wide-angle lens is a great depth of field of a lens. Depth of field along with photographic subject the shorter the distance the greater focus. 35MM wide-angle lens aperture on the F8, focus on 2M, the depth of field at 1.5-3.3M range is clearly visible. The same shooting distance, if 20MM ultra wide-angle, then from 90CM to infinity range is clear, and further expand the focus range. Put together from close-range to long-term focus are called" Pan Focus (Pan-focus)" , or" super focus" , this feature is used when the capture can not see the viewfinder, you want the photo shoot. Distant landscape photography depth of field is a basic, wide-angle lens in this regard can be said to be very effective.

How to make good use of a telephoto lens

we generally focus distance of more than 50MM lens called a telephoto lens (no special instructions for this are 135 systems). Widely used is generally from 105MM to 300MM lens, these lenses are also known as a telephoto lens. Super telephoto lens is more than 300MM 500MM, 800MM, they are also more than 1000MM.

feature of this lens has the vision to narrow the results. Super telephoto lens is used in the field of wildlife photography, or very far away from the goal to narrow the close-up shots. Also be used in the zoo does not close due to dangerous when the photography. Moreover, the close-up shots at the flowers do very effectively. The structure of the lens do not focus all out of that type within the lens, because the shortest shooting distance is short, the flowers, insects close-up is very favorable.

binoculars can do close-ups of flowers but the public Features a, 300MM lens photography in 5M at a distance can be taken by 1/13 times the magnification of the photo.

compression is the first specific description of the telescope characteristics. Close-range and long-term effect will be enhanced through compression. With 500MM, 1000MM the binoculars to zoom in closer to the sun, so the scenery on the ground and in contrast to the picture is super-telephoto lens is entirely familiar. Taken out of the sun will be reduced to the lens focal distance of about 1/100 times the size. Although the size of the sun no matter where on Earth the same shot, but if we can handle and vision of the landscape on the ground, close-contrast distance, rate changes will also appear. In view of this, when the sun and the scenery can change the size of the combination, you can shoot good pictures.

telephoto lens depth of field depth, with the focus distance The longer and become more shallow, the greater the blur. Further step, that is to be the depth of the scene produced beautiful blur utilize close-up shot on the. 300MM/F2.8, 180MM/F2.8 and other large-diameter lens is particularly effective for close photography lens, used in the shooting after the flowers on the scene can shoot beautiful photos to blur.

How to make a special lens

micro away from the lens

macro can focus very close to the subject, although macro attention is the lens close-up shots, but not only close-up with the vision and general shooting lens can get the same effect.

macro lens with 50MM, 60MM standard micro- away from the lens, there are 105MM, 200MM telephoto macro lens type. Standard macro lens advantage is small and portable, suitable for approaching the subject can be shot. There you can type telephoto macro lens from a distance closer to the advantages of the subject, is particularly conducive to shooting like a dragonfly dragonfly, butterflies and other insects is difficult to close photography. Unique virtual telescope first large-scale and highlight the subject features will further enhance the composition effect.

as a photographer from the very short, extremely close to, the subject almost touching the lens, this time to pay special attention to protect the lens.

fisheye

Sigma 15mm Fisheye

fish-eye lens is a residual income of poor lens distortion, so that we You can see the whole barrel distortion. Distortion from the center of the screen the picture angle of 180 degrees, but can reach 220 degrees special. Diagonal screen shot is about 23MM round fish-eye lens is called the circumference, as well as footage diagonal about 43MM round of the wider called diagonal fisheye. Then there are all the intercepts of the film 24X36MM, it is also known to shoot the four corners of the fish-eye lens.

no corners, shooting pictures for the diagonal direction of 180 degrees, 140 degrees the direction of length 36MM range, we generally put this lens called ultra-wide-angle lens. In the wide-angle lens on the use of close-up ring, you can capture a great sense of distance and focus particularly deep and unique photos.

reflective lens

reflective lens (return the lens) is a concave mirror used, so shorten the length of the lens to the lens. Its taste is very unique virtual, point-like light source can produce a circle-shaped blur. Is a description of the character has a unique lens, utilizing many of its features have to shoot a masterpiece.

how to make good use of shallow depth of field

When the focus and part of the subject in focus, the focus of the surface can be photographed as a distinct subject. If continue to rotate the lens focusing ring, there will be a little blur. Deviation from the nominal depth of field when the focus is generated when is our naked eye can not see the visual pictures unique phenomenon. Blur in the following circumstances become large: open large lens aperture (refer to the smaller lens aperture value), use a long focal length lens, shooting a short distance.

as a long focal length lens aperture small depth of field is even very shallow, so when using a telephoto lens is not only can shoot with a small aperture bokeh photos. With binoculars at close range photography to blur the background as a prominent theme of the description of the effect, so people like to be used for insects, flowers and photography.

large aperture lens using a shallow depth of field aperture, can also produce the effect of scene depth. People like to use in large-diameter telephoto lens and female flowers close-up, due to scene depth, easy to head out of the atmosphere in the telescope's unique beautiful blur effect dictates.

virtual is the theme of the subject before and after visible things, the rear than the front of the subject blur even more. Because of the virtual front than the rear of the virtual big, so when intake is close-range scenes of flowers, the large imaginary description of the perianth is very soft, will bring an atmosphere overflowing effect.

depth of field depth of focus is bounded at the front of the short, long back, but when shooting at close range before and after the depth of field depth is almost the same of.

as the virtual effects of the paint can emphasize the AF part, do not omit the part. In particular, complex background scenes shot, the use of virtual background can be highlighted as the theme of the subject. Predicted depth of field button on the camera. Is to allow the photographer from the viewfinder to confirm the status of virtual functions. As the camera from AF to see the bright reflective panel of the virtual than the actual screen is small, so consider this disparity hard to set the aperture.

naturalistic description of the basic landscape photography, general shooting method is to align the screen in focus after the corner of the screen is also taken into account. Therefore, depth of field narrow aperture to darken the Pan-focus photography method is the foundation. Through the lens focal distance means the distance adjustment ring rotated to adjust the depth of field within the ring set to infinity since the position is clear. Because relatively deep depth of field wide-angle lens, so the closer to close-focus distance over the side. If the contraction of the aperture, the closer will close.

a deep wide-angle lens view of the lens, though, but with F1.4, F2 class of large-diameter lens for close-up shots, the depth of field depth very shallow. When you need to remove unnecessary things in the background, blur blur it, weakening its existence, it can be a unique performance.

telephoto lens because the depth of view, close-up shots when the background can not clearly shown, but by narrowing the aperture can faintly see the background objects exist. When faced with making flowers needed to make people see the scenario described in the background when the subject, the other for the purpose of photography to record the case, through the narrow aperture makes the background gradually clear up, so choose the right aperture is necessary.

button to use the camera's depth of field can be predicted forecast to set the aperture depth of field effects.
