The characteristics of vice factory lens

Besides casio np-100 battery vice factory lens, a lot of people choose this kind of reason is the price shot relative cheap, such as your price is the latter nikon ley lens has nearly doubled, to measure is cost-effective want purchaser. Although generally cheaper vice factory lens, but this does not mean that the imaging quality vice factory lens are not high, Most of the optical performance lens vice is quite good, even beyond the ley lens, such as tenglong SP AF 90mm f / 2.8 Di MACRO lens performance, this one, and a reputation for a lot cheaper than original to; Optimum horse 50 f / 1.4 EX DG HSM lens is a market reaction good lens, arguably, the production technology has standard lens quite mature, but comfortable not only developed horse again, and such a lens than reality show its original still expensive, have outstanding place optical quality.Casio QV-3EX battery

The famous manufacturer mainly vice factory lens optimal horses, tenglong and FIG. Beautiful. Three major brands each have special, suitable price is outstanding, horse lens cover of focal length is complete, but in lens coating has been being reviled. Tenglong lens although using plastic material design, but the imaging quality. Figure li lens work very good, can and original, but the product of comparable camera update at a slower speed.Casio QV-EX3 battery

Photography is looking for from the light and shade

According to the camera sony np-bg1 charger, be taken body and light source position relations, light can be divided into several basic direction: frontlighting, side light, backlight and top light, different radial direction will build a completely different shooting effect.

The light from the back of the camera sony dsc-s980 charger to illuminate the direction can be adjusted, the light of the body is light (or says the positive light). The characteristics of the light that can be adjusted by light, light body even smaller than and contrast. The photograph is a two-dimensional image, it's depth, outline and stereo feeling all depend on the interaction between light and shadow to performance. The subject of frontlighting filming smile, lack contrast, appear more associated and level, the lack of a "flat" stereo feeling, so frontlighting also called classification includs glass.

At noon, the sun from people head upper part illuminate down such light is called "top light". You can actually understand the light from overhead shot over 90 ° side light (try to put pictures of 90 ° side light to the left or right turn 90 °, can have pictures of the light effect). So it shadows and 90 ° side light some similar, is just a left, right, the contrast of a.

Photography is the art of light and shadow, the light can paint ", the "photographer for the photographers can spill negatives usual

Ink. Photography Battery Charger process also a photographer to create? Actually, are suitable. The skill, the photographer, will view the original flexible use of light, create the different style, pleasing pictures.

Teach you to build the coarse particle image effects

The photos sony bp-65h battery taken by coarse not produced by the body, but the photographer subjective a special expressional gimmick, can produce in photography course and photos of post-production process. Usually, the thick, required granular pictures of the more sophisticated production process. Below, just black and white photos and color pictures to produce the method of making coarse effect respectively to talk.

Black and white film showing mode and particle effect is proportional to the slower particle photographic, more exquisite; Photographic faster, more bulky, filming particles should choose when high-speed photographic film. In addition, still can by changing the exposure and film to obtain coarse enhancement conditions effect. Filming intended for insufficient, then in photographic film for developer heating, enhancement and prolongs the time, strengthen the enhancement, can make the film developed particle coarsen. sony bp-l90 battery

However, even use the above methods, if in the last photo, photo size made such large and film or older, coarse particle effect also don't reflect. Photos of the higher magnification, particles, the greater the effect became more bulky. If want to enlarge, undertake local adjust composition, coarse particle effects will be more apparent.

On the color photographs sony bp-l40 battery of particles, but not metallic silver color piece. Coarse particle effects often make photographs became like impressionist point color works. Color film and black and white film, same photographic faster, particle effect of the more notable. However, due to the color film color particles with general method, very subtle, to make its realization coarse particles. To achieve the expected effect, can use the following two methods:

(1) amplifier reversioning method. Use first color original bottom with a large portrait (take a local effect negative better) and nearly perturbation put reversioning photographs of the picture, part renewable negative again, the picture and put system can present a very rough particles.

(2) microscopic shooting method. If want to put the negatives of the local bigger, can use a microscope. Of course also need a SLRS and answering cone, from microscope to directly screened magnified dozens of times even hundreds of local image. The original film The negatives of the images will get many times than the original film amplification, color patch and trenchant.

Of course, both black and white photos or color photograph, can pass another kind of mechanical means to obtain coarse particle effects. Enlarge photo, put a piece in film coarse anilox (or the film clips on the frosted glass amplification), so the achieved result often pretty good also. sony bp-l60s battery

What is light? Talk about aperture function and representation

In order to facilitate in real photography jvc gr-d30u charger calculation with unified exposure and to measure different lens aperture aperture, the actual role adopt "relative aperture" concept.

Aperture say again aperture aperture, is the important mechanical device, shot by changing its role is the effective optical lens aperture, control the light through a lens, thus make the ability of photographic jvc gr-d93us charger components or film get accurate exposure, and can control of the depth of field, or adjust the imaging quality lenses. Aperture are in lens aperture, usually by more pieces inside the metal blades can be activities (called the aperture of blade), can undertake no series of adjustment. Aperture institutions by mechanical or electric, can electromagnetic device driver, also can manual adjustment.

Aperture position

Due to the different lens aperture from different locations, focal length, diameter of different incident pupil with aperture is not identical also, described the light ability, general lens cannot achieve different lens comparison. In order to facilitate in real photography calculation with unified exposure and to measure different lens aperture aperture, the actual role adopt "relative aperture" concept.

Relative aperture = [focal length of the lens] / [incident pupil diameter] = f/d

Usually indicate relative aperture method is in relative aperture front join [f /] or f, such as f / 1.4, f / 2, f / 2.8 etc, f/or f numerical smaller, behind the transmittance level; Digital is larger, the smaller the transmittance level. With such standardized way, for different lens, shutter speed, under the condition of invariable, same as f numerical exposure is the same.jvc gr-d395us charger
