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

Note the reflection shooting

Specifically, the shooting should note the following:

(1) to clarify the FUJIFILM NP-50 Battery characteristics of a variety of reflection to grasp moderate exposure data (correct choice of shutter, aperture combinations and viewing angle)
Mostly produced by the reflection on the water, bright reflective light to deceive the photographers and the table, resulting in light intensity higher than the actual state of illusion. Then open the aperture should be compensated, to ensure accurate exposure, the best classification of the exposure to take some pictures, pick and choose the most satisfactory. Often reflective surface, to prevent lens flare, plus the best polarized lens when shooting.

(2) the FUJIFILM NP-60 Battery composition should be of better and real reflection of the distance ratio is almost so big; closer reflection, due to the difference in elevation view to show the number of points; reflection of the number and height is inversely proportional to the viewpoint, in addition to special needs, it is generally not appropriate to the formation of reflection on the water screen is symmetrical, one side should be a bit more, so that a balanced composition, and there were changes in the uniform to avoid stiff.

(3) reflection in the wind tend to be divided into strips or deformation illusory, bump on the road there will be intermittent due to stagnant water or partial reflection, then often get unexpected results, so the photographer can not be easily missed opportunities.

(4) reflection and the entity should not have perfection, the amount of the performance of site conditions should be considered or intended to take less from real reflection, or reflection, taking less and get real, real do not even take the full amount of reflection. Some deformation of the distorted reflection of the film well, there will be a special charm.

(5) reflections drawn Location: wonderful reflection can be seen everywhere, river fishing, Wu Tong, pools, rain water, clean the floor, ice, etc., almost can see a variety of reflection. Regardless of direct light, scattered light, even under the lights at night also have a reflection of the photographer as long as you pay close attention, is not difficult to shoot attractive masterpiece.FUJIFILM NP-95 Battery
