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

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
