Digital camera in various focus the lens of the application

If focus speed is very important for you,FUJIFILM Digital Camera Battery in buying a af camera before, must to af function test of patience.

The fujifilm np-30 battery conventional lens is depends on the move the whole lens system or before moving to realize the focus lens groups, and the focus lens in the focus group lens will not happen before the displacement.

Some of the biggest zoom lens aperture depends on the focal length setting. This system is used to reduce the size and weight of the camera fujifilm np-40n battery, but the restrictions on the exposure setting choice. If possible, must choose the maximum aperture fixed the zoom lens.

Macro lens normally used for filming close objects, used to reflect the true size or enlarge effect. Usethe zoom range for 50-200-mm zoom lens, can avoid image deformation.

Dazzle by sunshine point-blank light is bright object lens fujifilm np-40 battery or other directly on the cause of the lens. The light from the lens front point-blank come in, make lens internal light intensity increases, it will appear in the image polygon glare, glare of composition and artistic effect too much no good, in front of a camera lens hood help to stop the direct light to reduce glare. Suggest using manufacturer's recommended hood, especially in the use of the wide Angle lens, it can avoid the lens hood greatly and reduce produce dizzy light perspective.

Dark parts of metering of light of the detail of the lost exposure photography skill

When the subject subject and the FUJIFILM Digital Camera Battery background picture of a contrast of large, for example we in photography stage actors of the above. The stage is the picture of the dark background, but an actor in a chase light under, lighting is enough, we frame, scope and relatively large. Then the dark background on metering table up a major impact, if we according to the data for exposure photography, will lead to excessive exposure main characters.

Against the dark department for fujifilm np-40 battery metering shooting, so bright department will lose the details should be excessive exposure. At this time may choose to use the camera local metering or for center-weighted average metering or spot metering mode for exposure condition, also can choose close to the main body characters metering, according to the ministry of light and dark picture of a rebound in the analysis, as appropriate, to reduce exposure to shoot.

The actual shooting, due to the needs of the composition, the main body of the perturbation is often not arrange in the picture. In addition, the whole picture objects on the brightness of the light reflected may have very big difference, especially under the condition of light shooting, light than will be larger, so, in fujifilm np-70 battery light of the complex, the central focus on average metering way also can't fully satisfy need.

Take the main body figure for metering area, and referring to the given data properly reduce exposure.

Digital camera P program to be automatic exposure mode

Program mode is a digital camera FUJIFILM Digital Camera Battery the product of the era, microelectronics integrated chips in the camera, the application of automation function that camera more perfect and provide a lot of convenience for the photographer. Through the digital camera built-in metering system to collect and be taken body brightness data, by electronic integration chip calculated accurate exposure and shutter speed. The modern digital camera to provide us with a lot of shooting model.

Main introduction on common mode, such as AUTO automatic shooting model, P program to be automatic exposure mode, A/AV aperture priority to be automatic exposure mode, S/T shutter priority to be automatic mode and manual shooting Digital Camera Battery model function characteristics, use method and the matters needing attention.

P program to be automatic exposure mode is refers to the digital camera according to the light, automatic shutter speed and aperture setting, the photographer can be set to other parameters. And AUTO ae shooting model is very similar, but different is the constant exposure, the photographers choose a most with filming the intentions of the aperture and shutter speed combination, and at the same time the photographer can also set GanGuangDu, and white balance parameters.

In the night USES program fujifilm np-40 battery to be automatic exposure mode to shoot, phase chance to open the flashing light, if do not use a flash it needs to ISO raise, also can prevent the shortage of exposure.

Article 12 classic photography skills

Photography is an art, need more of is technology,casio np-20 battery is also the accumulation of experience. Below is the experience of countless photographers gathering a article 12 most classic, practical photography Tips, hope that you will its knew by heart, this will help you cope with a lot of difficult to access the shooting scene.

1. Sunny 16 Rule

"Sunny 16 Rule" is on the list, so no correct estimation of the casio np-40 battery sun exposure numerical method, so this Rule only in the Sunny cases suitable for use. Will the aperture set to F / 16, the shutter and ISO synchronization, or slightly faster. Such as, ISO set to 100, when the shutter should establish for 1/100 SEC (1/125 seconds). So, according to this law, on the beach when photography, should use F / 22 aperture in the cloudy, should be used when the F / 11 aperture.

2. Moony 11, 8 reflected 5.6 Rules

If you want to shoot the moon, so here casio np-60 battery are a very good law. The shutter and ISO synchronization of the time, the shooting full moon in F / 11 aperture, string month in F / 8 aperture, crescent USES F / 5.6 aperture.

3. Camera Shake Rule

When armed with a camera casio np-100 battery shutter speed filming, not less than the bottom of the focal length of the lens. If the slower shutter speed, so when shooting the jitter may lower the sharpness. If with 50 mm focal length of words, the shutter will achieve more than 1/60 of a second, it is advisable that only when the environment is dark, with the flash, feet frame or put the camera on hard surface prevent wobble.

4. Anatomical Gray Card

Carry 18% of the medium gray plate is Casio QV-3EX battery shot of the tool. But if no gray on board? Can your palm spread out your face to the sunshine, palm, and then on to add a exposure metering.

5. Depth of Field Rules

When the subject is deep eight-line, Casio QV-EX3 battery should choose to focus in depth of field, because such a third place before, the focus is the depth of field after before 2 times. All kinds of aperture and combination can be used focal length this law. Remember, the smaller the aperture, the shorter the focal length, range was taken object more far, the greater the of the depth of field.

6. Largest Digital Print Rule

If you want to put your work printed into Casio QV3000-PROPACK battery large size photo, photo size is not greater than digital images of the breadth of pixels each divided by 200. If you work requirements of high, then at least divided by 250.

7. Exposure Rules

In the treatment of the digital photo, the most Casio XV-3 battery common law is to guarantee the accuracy, low exposure specular area light area with his. But the negative, especially when dealing with the color of the negative, you'd better add a aeration.

8. Quick Flash-fill Rule

When your camera can't automatic output control flash Casio NP-130 Battery, flash will be set as the autoflash film by two. If the main body, the user-selected aperture the metering block, set to the same flash aperture. So, photo the area will than the subject brightness low gear.

9. Flash Range Rule

This law is very simple: distance multiplied by 2, 4 times mode. For example, your flash in the ISO 100, the effective distance to 20 feet. If you want to make flash distance to 40 feet, need to ISO 400.

10. Megapixel Multiplier Rule

If you want to make a digital camera resolution increases times, so very simple, is to quadruple the pixels.

11. Action-stopping Rule

This law is based on the experience of the Angle and speed formula. If the body of the lens axis motion you can use 1/125 of the shutter capture,Casio NP-L7 battery it after as to the lens axis movement can use 1/500 capture down. That is, if the object along the lens axis says 45 degrees of sports, only need to 1/250 of the shutter speed.

12. Sunset Rule

Shooting the setting sun, to the upside, but can't let the sun metering appear in your viewfinder. If want to let the sunset looks better than the actual one hour later, can reduce 1 in exposure compensation.

The above 12 law you to remember it, but this is countless photographers accumulated experience it.Digital Camera Battery

The landscape photography four skills

1. Find the best place

In order to save the Digital Camera Battery destination wander around in time, prior to do a little work.

You can through the Internet, books or the local tourism information gathering will shoot destination of relevant information, see the local what was taken photos, think about how you can do better.

You appreciate the reference of the photographers is not a fujifilm np-70 battery shame, from their works of learning how to make composition, how to use the light, it is very necessary.

You can also look at those outdoor activities, such as fujifilm np-40 battery hiking, camping information, mountain climbing, bicycle and drift, the information will often mentioned in some scenic sites.

Can also and other photographer's exchange, through the fujifilm np-80 battery network asked for their advice, where is worth to and where should give up.

Once you get a "will to place" list, you can take the package set off.

2. Waiting for the right light

Because the light and protean landscape.

Consider in outdoor shooting scene, most cases are only a FUJIFILM NP-50 Battery light source can use: natural light.

Many believe that the best landscape photographers light from the early hours of the morning sun-before and after sunrise one hour of time.

Others think that sunset is more vivid color of light.FUJIFILM NP-60 Battery But the winter sun at noon in the most suitable for taking pictures.

Whether you have any preferences, also the arrival time in advance, so the position of the find shooting, set up the camera and then wait for the sun performance start.

Remember, to bring a comfortable chair, a bottle of hot drinks and a thick clothes.

3. Composition

Lack of composition elements of the scene is very dull, so to use FUJIFILM NP-95 Battery other object to arrange your picture composition, think about what will attract someone the eye.

In filming locations around around move around, found you interested in landscape or items, and the use of a composition guidelines to set up the picture, such as the rule of thirds, symmetrical or golden section, etc.

Pay attention to your eyes those elements of the terrain, and they are how to cooperate with each other effects. For example: the horizon, the trend of the mountains or a piece of the lake. Consider the space between you and them, and how to composition can form the most interesting picture. Shadow and reflective would be the most FUJIFILM NP-120 Battery interesting element?

Arranging some lead of the view of the future of the elements, or some guide line. Such as road, river or tracks, these lines can be introduced into the line of sight of the picture.

In you before the shooting, ask yourself "in the picture makes me feel that the most interesting where?" "This composition enough to attract me?" And "the most interesting places in where? I will be their best to show out?" To these questions, you feel as objective interesting places, people will soon found to.

Remember, although you are filming the scene photographs, but this does not mean that you are limited to the narrow range-scenery to do more to try!

4. Pursue the perfection

Adjust the tripod height, find the best photography Angle: if the feet too low, seems to be a scenery is flat; Too high, the prospect may appear skewed.

Give a tripod hang stone bag (the axis backpack too), sudden wind effects stability. If you have a tripod and use it to ensure leveling composition is level. Remember camera wants as far as possible some fixed tightly.

Close shot the FangDou switch on camera ISO set low to 100 or 200. If your opponent move have confidence, consider using exposure long exposure, especially at dawn and dusk light to compare weak. Long exposure can will seawater and clouds grammaticalization movement, build a fantastic result.

If during the day, or light shooting more intense, and consider using the FUJIFILM NP-140 Battery ash filter weakened in the light of entering the lens, also can achieve long exposure.

Use aperture priority mode, and the opportunity to create different depth of field effect. Want to get a wide coke, can use in imaging f / 11-f / 22 or so aperture.

Use check, make sure the image playback details and colour lively, learn to sharp see histogram to control exposure.

If the camera allowed and memory card capacity, it is FUJIFILM Digital Camera Battery recommended to use enough RAW format to shoot. In the post production, you can contrast, colour and exposure to full control, in order to achieve perfect level.

You should know about sports photography Tips

"What kind of equipment to?"

Generally speaking, you need to prepare two sets of SLR fujifilm np-40 battery, a first match on 70-200/2.8 such large aperture telephoto lenses, with a standard zoom lens, can also according to individual circumstance with a header or to record the entire site wide-angle lens of the atmosphere;

"How to set up your camera?"

Indoor and outdoor sports have very different lighting conditions, so you first need to judge you will face light conditions, light good sports include tennis, baseball, athletics, football, poor light sports including basketball, table tennis, volleyball, and so on project (ready to show the students must pay attention to yao Ming oh).

The shutter: whatever you in indoor or outdoor should at least ensure you shutter speed at 1/250 SEC above

Aperture: light environment good outdoor case, use fujifilm np-80 battery ISO200 mode, match with F8-F11 aperture will bring you preview very ideal photos, if can the shutter improve to 1/500 s above, will be enough to capture the fastest speed instant, the athletes In indoor sports photography, you often need to use F2.8 F4 aperture, and matches-with high ISO values to gain higher shutter speed;

Save format: sports often use even shoot mode, so you need to weigh the storage RAW or JPEG, the former will soon fill your machines cache;

"Focus" most SLRS has three focus mode (AF-A/AF-S/AF-C), and shooting sports generally use AF-C continuous focus mode, of course, and, in some cases, in advance of the lock focus "trap type" focus also easier.

"Finding the best shooting position" Angle composition, and a favorable decision in shooting fujifilm np-70 battery position more likely to capture the natural key of the screen, for example in the basketball game, on the left side of the basket more easily catch to dunk the complete picture of;

"Don't focus only on action" the most wonderful moment not only the action of athletes, wait for the results the tension, the joy of the victory and defeat the lonely will reflect the athlete's expressions, grasp of human nature is often the images can move more in the hearts of the people; Digital Camera Battery

Lithium ion battery capacity loss reason analysis

Capacity loss analysis of the causes of charging is charging so-called charging more than the prescribed termination voltage (usually 4.2 V) and continue to charging process. In the case the overcharge causes battery casio np-20 battery capacity attenuation, basically has the following factors: (1) the graphite of negative overcharge response; (2) positive overcharge response; (3) when electrolyte oxidation reaction in overcharge. The battery in the overcharge, lithium ion easy reductive deposition in Li++ e > anode surface: Li (s) deposition of lithium wrapped in negative surface, blocked the lithium embedded. Lead to discharge low efficiency and capacity loss, reasons are: (1) the circulating lithium decreases; (2) the metal lithium and sedimentary solvents or supporting electrolyte Li2CO3, LiF reaction formation or other products; (3) metal lithium usually forms in between anode and diaphragm, may increase the porosity of the obstruction diaphragm internal battery. Fast charging excessive, current density, negative serious polarization, lithium deposits will be more apparent. Positive overcharge cause capacity loss is mainly because electrochemical inert substance (such as Co3O4, etc) Mn2O3 produced, destroyed the capacity balance between electrode, its capacity loss is irreversible.

> (1 - y) / 3 [Co3O4 + O2 (g)] + and positive materials in seal of lithium-ion battery casio np-100 battery to break the oxygen produced don't exist again due to combined reaction (such as generating H2O) and electrolyte decomposition inflammable gas engendered and accumulation, consequence will be unimaginable. Overcharge also lead to electrolytes, the oxidation rate oxidation reaction with positive material surface area size, set electricity body material and add conductive agent (such as carbon black) has the very big relations, meanwhile, the type and size of carbon surface of electrolytic liquid oxygen is also affect one of the important factors, the surface area is larger, more easily in solvent surface oxidation. When the pressure when than 4.5 V electrolyte will oxidation generating insoluble, (such as Li2Co3) and gas, these insoluble, can jam the microporous inside the electrode block lithium ion migration and cause circulation process capacity loss.

Electrolyte decomposition by solvent and electrolyte supporting electrolyte component in the positive decomposition usually forms of insoluble products such as Li2Co3 and LiF electrode, through the obstruction of the pore and reduce battery capacity, electrolyte reduction reactions battery capacity and circle life will produce the bad influence, and because the reductive produced gas will make a battery inner pressure increases, leading to security issues. Electrolyte in graphite and other intercalated-li anode carbon on stability is not high, easy to the reaction that produces the irreversible capacity. When first charging and discharging electrolyte decomposition form in the electrode surface passivation membrane, passivating film electrolyte and carbon can be separated stop electrolyte anode further decomposition. Thus maintaining the structure of carbon cathode stability. The ideal conditions electrolyte reduction in the formation of limited passivation membrane, when circulation stabilization stage after this process is no longer occur. Electrolyte salt reduction in the formation of passivating film, to the stabilization of passivating film, but reduction of insoluble, produced using solvents recovery detrimental effects, and electrolyte salt reductive when the concentration of electrolyte, reduced, eventually lead to battery capacity loss (LiF, LixPF5 LiPF6 reductive generation x, PF3O and - PF3), meanwhile, the formation of passivating film consumes lithium ion, that leads to the poles caused by the unbalance between capacity battery BiRongLiang reduced. The type of process using carbon, electrolyte ingredients and electrode or electrolyte of additives are influence factors of film capacity loss. Electrolyte middling often contains oxygen, water and carbon dioxide and other substances. Trace amounts of water on the graphite electrode performance didn't influence, but water content is exorbitant generates Li2O LiOH (s) and, to the detriment of sedimentary lithium ion embedded, causes irreversible capacity loss: H2O + e - OH - + 1/2H222 OH - + Li + - LiOH (s) Li++ e LiOH + Li2O (s) and the CO2 in negative + solvent can generate CO and LiCO3 reduction (s) : 2CO2 + 2e + 2Li + - Li2CO3 + will make a battery inner pressure increases, and Li2CO3 (s) make a battery resistance increases affect battery performance.

Self-discharge self-discharge refers to the battery casio np-60 battery in unused natural condition, the phenomenon of electric capacity loss. Lithium ion battery self-discharge cause capacity loss divide kind of case: one is reversible capacity loss; 2 it is not reversible capacity loss. Reversible capacity loss means loss of capacity can recover in charge, but not reversible capacity loss, by contrast, such as lithium manganese oxide anode and solvent will occur microcells effects self-discharge causes irreversible capacity loss. By approximately 400mah life.low self-discharge degree, battery manufacturing process, electrolyte properties, temperature and such factors. If self-discharge rate by solvent oxidation rate control mainly, so the stability of the solvent storage life affects the battery anode in enough electricity, if the state and positive happen, battery capacity balance within life.low self-discharge are destroyed, will lead to permanent capacity loss. Long time or often self-discharge, lithium likely increase in carbon deposition on two levels, imbalance between capacity levels. Pistoia life.low self-discharge oxidation product that such as electrode material of the blockage, lithium microporous embedding and emerge difficulties and make resistance increases and discharge low efficiency, thus cause irreversible capacity loss. casio np-40 battery

The background light still life photography

In still life photography fujifilm np-70 battery in Taiwan usually still life or still life in the latter part of placing a box background cloth, the color can be black, white, red, blue, etc., to act as a still life in the background. Simple background can be more prominent subject. But this film out of still life will inevitably become dull and monotonous. If, like indoor portrait photography, layout set in the background light, the screen can create a certain atmosphere, make the subject better results.

There are two ways to layout the background light. One is the upward projection of small lights in the background fabric, so that in the background to generate a lighter area, the atmosphere of the picture contrast. Another method is to the rear of the cloth in the background with the lights directly, if the light is too strong, can be installed in front of a white paper or light cloth, cloth by the light in the background so the site will produce a circular light areas.fujifilm np-80 battery

Background light can make the photos have a more refined, mysterious effect. Under the guidance of light in the background, the viewer can soon put the focus on the still life subject. This method is widely used among commercial advertising photography.fujifilm np-40 battery
