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
