Dynamic photography is the focus of the FUJIFILM Digital Camera Battery movement for performance photography theme, sports photography shown by artistic conception and picture effect with other subjects photography very different, it by showing the state of motion activists conveys strength and beauty, which show competition, healthy and upward thoughts, the images infectious and visual impact. Usually, the photographer to telephoto lenses, proper shutter speed, and follow through to the foreground subject shooting performance state of motion.
Use the FUJIFILM FinePix F810 Battery tripod photographer to fixed camera, and use a little slower shutter speeds to display the dancers move feeling. Use the tripod to jump shot photographer of the characters, but, the photograph also is to display dynamic fuzzy and the use of a low speed shutter, through the main characters of the image is behind the characters of clear, show that the stability of the camera on a tripod effect is obvious.
Filming on the FUJIFILM FinePix F100fd Battery basketball court, for example, the shooting global game better position is in the midfield higher position, such already to film the global game and can capture close-up, taking the best location shooting the ball near box way.......
The photographer to telephoto lenses and use the shutter capture game players battling for the goalkeeper and the picture. Because the photographer to hockey very understanding, foresaw the upcoming battling for the Digital Camera Battery screen, so the "artificial intelligence servo autofocus" model caught this wonderful scene.

How to select the metering environment obtain satisfactory exposure
By bobo anthony on Tuesday, February 28 2012, 02:04 - Digital Camera Battery
In photography FUJIFILM Digital Camera Battery to think of when the correct exposure, you have to press the door quickly through evaluating to determine how much exposure to the, light conditions, the object from densest to the most bright dark place has the many levels of gray-scale transition, the camera to be automatic metering principle is to glance rate is 18% reduction scenery in the grey as the basis, according to the reading of exposure to get accurate exposure.
When the subject body two relatively even distribution, in all metering mode can be used for flight, but in the backlight mode or is main body and the background of brightness is very wide filming, not in the central focus for too much for the seat area mode metering. In the spot metering, local metering mode, must on the subject for area glance rate at about 18%. The part of the
Metering makes the Digital Camera Battery picture light and shade configuration and light and shade contrast bright clear, scenery rich administrative levels, the space is clearly perspective, in portrait photo taken by metering, attention shall be paid to be smooth and shadow face on the picture of proportion of, like, for example, by smooth and general taboo shadow face evenly split.
The fujifilm np-40 battery general to the side of the body was taken 45 ° Angle above the before and after that the daylighting of the best light is Angle, equivalent to about 10 o 'clock in the morning and afternoon at about 2 of the light from the sun, is for the same film, high Angle of the main body of the shadow when a short, low Angle of the main body of the shadow when a long, get exposure effect is not perfect.
Whether manual exposure, or fujifilm np-70 battery automatic exposure, is dependent on film, if not for accurate, the shooting results you must not beautiful, so necessary to improve the shooting in the accuracy of the film.

The chemical composition and photographic film performance
By bobo anthony on Thursday, June 9 2011, 02:02 - Digital Camera Battery
Although use electronic image sensor photosensitive digital camera FUJIFILM NP-50 Battery has become the mainstream of the current market, but many photography enthusiast still clung to film cameras; For today's most introductory lovers, the film has gradually become a "mysterious legend". Perhaps we have seen it, but would not necessarily know the basic working principle and film chemical compositions. Therefore we invite senior photography enthusiasts rice meal for everyone to do detailed introduction.
After who see the light, can follow the light intensity happen to produce "latent-image different after a certain" and then the chemical or physical treatments can produce visible image photography materials, namely called "photosensitive material"; The film, a CCD, CMOS are. Now digital camera image sensor adopts photoelectric transformation of energy to produce images, and traditional film is mainly USES the chemical changes to achieve the same purpose. The film light-sensitive materials can be divided into silver films and the silver film two kinds, the first kind is introduced as silver film (below - the main film) chemical composition and performance.
Film enhancement
First of all we want to know, the film consists mainly of "photographic emulsions" and "emulsions FUJIFILM NP-60 Battery support the body" composition. The main components of the emulsion is gelatin and granular halogenating silver and silver evenly dispersed halogenating YuMingJiao; And support to use a different body because paper-based, tablet and glass, they and emulsion products for the combination of corresponding ZhaoXiangZhi, film and YingPian (GanBan). Next we detailed halogenating silver, gelatin talk the specific chemical composition and the enhancement of influence of performance.
Second-ranking halogenating FUJIFILM NP-95 Battery silver
The so-called "silver" means halogen and metallic silver form the floorboard of the compounds, here we mainly discuss silver chloride, XiuHuaYin and silver iodide. Soluble in water, silver chloride higher molecular weight of silver, solubility lower; It is very short purple of wavelength area and ultraviolet photosensitive; XiuHuaYin photosensitive area light to blue; The role of light-sensitive silver iodide focuses on increasing range. If XiuHuaYin mix of silver iodide and adding range, photosensitive emulsions HaoWeiMi reached 500.
The photographic FUJIFILM NP-120 Battery emulsions different halogenating silver composition, photosensitive sensitivity is different, press photosensitive machine speed permutation order is adding trace of silver iodide - XiuHuaYin of photographic emulsions XiuHuaYin second, the quickest and most slow silver chloride. According to these characteristics, generally negative emulsions contain XiuHuaYin and small amounts of silver iodide, and silver chloride applies only to low-speed positives emulsions. Halogenating silver crystal grain diameter scope for 20 to 50 microns to 50 nano, most in the diameter size between 0.1 ~ 4 microns. According to its type, shape, size and distribution, largely determines the photosensitive material characteristics, such as photographic speed, solutions like force, contrast, etc. As commonly used silver chloride to get fine particles, high contrast or makes images to palm black tonal.
Second-ranking gelatin
Gelatin from the FUJIFILM NP-140 Battery skins of animals, bone extract a high-level glue, gelatin is sensitive material in the film was the biggest, the most complex dosage of the raw material, performance with many functions, basically has the following three points:
1, decentralized and suspended halogenating silver, prevent its sedimentary - gelatin sticky properties that make emulsions in piece foundation to coating film, forming the emulsion unifor thickness, prevent fall off. Layer Gelatin can be adsorbed on silver crystal surface, achieve halogenating uniform separation crystals, prevent gathered and sedimentary role, this is silver light-sensitive materials can form clear accurate imaging important reasons. Gelatin concentration have certain influence on photosensitive properties, such as increasing concentration can form the more fine halogenating silver grains, increase contrast to reduce mode and the results.
2, development, has gelatin silver grains, is wrapped halogenating photographic difference of parallel to the imaging difference - halogenating silver necessary conditions in a light-sensitive chemical properties of lively will immediately be restored after. Gelatin chemical inert package of silver, discussed the spontaneous reductive resistance in the developing process, make halogenating reaction that produces the lag between the silver reduction, begin from photosensitive strong section begins, restore the fujifilm np-40 battery image.
3, the increase feeling and inhibition of gelatin substance, can improve HuiWu mode and inhibition of emulsion according to the impurity in - gelatin role for sulfur classification can fee increase feeling agent (sulfide impurities), reduction increase feeling agent (aldehydes and ketones) and inhibitor reduction (close to gelatin molecular weight of sulfur protein). Sulfide impurities can cause silver-contained atomic bomb photosensitive nuclear generated halogenating silver crystal, increase the quantity and improve photographic nuclear photographic speed. In addition, gelatin silver reduction in halogenating reaction with off halogen ion, prevent and reduce halogen ion and silver again, thereby improving emulsion layer with photographic efficiency. Different materials gelatin contains three kinds of material of different proportion, produce different characteristics, such as small cowhide can make give inhibitory supreme gelatin, whale skin less, but HuiWu gelatin liquor mode is not high.

Beginners photography common errors
By bobo anthony on Wednesday, April 20 2011, 05:42 - Digital Camera Battery
In photography FUJIFILM NP-95 Battery practice, inexperienced beginners, often appear a few mistakes. The author put beginners common fault separately, and briefly analyzes the reason and gives the prevent mistakes method for beginners reference. 1, with pictures of clap a wide-angle lens dark corners Is mainly due to flash with wide-angle lens coverage does not match the view Angle. Older flash design flash coverage of 35mm mostly only small wide-angle lens kit, the view Angle rounded on the wide-angle lens than 35mm lens big 12 degrees, thus making the pictures by less than the light and dark around. Prevent way has two, one is in the lamplight to add astigmatism mask, scattering, flash become to expand coverage; 2 it is covered with white gauze lamp, let the light scattering, make whole picture by light can be evenly. 2, the pictures associated fuzzy In ruled out camera trouble-free and hand earthquake, etc, will check lens causes by dust covered or whether by besmirch dye coating. If encounter this kind of situation, avoid by all means blow with the mouth or a towel. Application blows balloons blown away the dust of the lens, reoccupy lens brush brushed sundry, finally, with lens paper wipe lens bright as new. If still have sweat be soiled, fingerprints and oil dirties, will send camera repair shops with lens cleaner liquid carefully remove. Three main characters fuzzy, background, legible There are two possible manual focus, one is the focus, focus the camera to the subject or subject without in composition focusing, and moved location, not to focus, make the main body is not within the scope of depth; Second is the use of af camera, did not press the shutter "locked" composition, and again to focus elsewhere in composition to focus will shift. 4, group photo photo after a few clear, before a few fuzzy According to multiple rows, who took to ensure that every person, will do three images clear: one is selective focus. Five rows photos, choose the second row focus; Seven rows photos, choose the third row person focus. 2 it is aperture don't set up too big, general with f4-8 advisable, to ensure that there is enough of the depth of field. Three is a shutter speed never less than 1/60 seconds, lest someone head turn make images FaXu. 5, film no exposure There are two main reasons: one is the paraxial point cameras jie lens cap, when forget in clear, but the viewfinder scenery without entering the lens, the imaging light no photographic film. 2 it is manual volume slice of 135 SLRS pack piece does not reach the designated position, roll a little did not look whether in the corresponding slice Windows axial rotation. Because picking slippage, move coil slice handle, although the shutter on the string, counter usual count, but the film in grain silk in Windows still, no counter after 36 pictures though shows, in fact, not a photographic film. 6, photographs FUJIFILM NP-120 Battery to be dark corners There are two main reasons: one is the focal length of the lens hood and do not match. Of the 50 standard lens hood used the wide-angle lens rounded on the focal length will block the light entering the lens. The view Angle for header for 47 degrees, and the view Angle rounded on the wide-angle lens for 75 degrees. The second is with rounded on the wide-angle lens photography, the original already on camera wearing a UV lens, if be wearing a polarisers words, because polarisers is two pieces of glass composite and become, frame is very thick, plus the border in UV mirror, will keep out into the light, make the photo lens dark corners. Filming as needed with wide-angle lens, must first polarisers discharged after UV mirror, polarisers reload makes images by light can be evenly. 7, white or black death associated data, the lack of shadow grain level Whatever is black and white or color photos, only exposure accurate, can obtain the lively associated and rich administrative levels. Photos die white is exposure excessive; Hi black is underexposed pictures. According to the metering inside machine is 18% of mid grey reflective rate designed, it can make the most exposure accurate, colour reduction scenery, but encountered some special light or scenery, when need is conducted on the basis of metering modified. Such as shooting FUJIFILM NP-140 Battery without increasing 1.5 - snow like exposure, grade 2 snow will become gray; Such as shooting of coal, if not reduce 1.5-2 levels of exposure, black coal will become a dark grey. Because no matter how advanced camera, no thinking function, will only put all scenery in machine-made glance rate of 18% grey adjustable processing. 8, with electronic flash perturbation photos still under exposed Two reasons: one is the aperture setting is too small. Speed of flash lamp are commonly 1/10 seconds above, shutter has lost control light effect, depend mainly on aperture size control exposure. No auto flash pictures, first calculation aperture coefficient. 2 it is flash power shortage. The new flash to pass the charger, more than ten times, let light inside capacitance discharge before officially use after active. Old flash charging lights lit only about 70%, filling in lighting can truly after 10 seconds, charging full for normal use.Digital Camera Battery
