See so much about Digital Camera Battery knowledge. But how to differentiate between the class of the digital camera? We know high-grade professional digital camera prices to cost tens of thousands yuan, why would so expensive?
And what is the professional digital camera, distinguish standard is what? More than 5 million pixels digital frame turbidity professional digital camera? Weight more than 1 kg is called a digital camera? More than 10000 yuan price in of professional digital camera casio np-20 battery? These could make a lot of perturbation friends puzzled and now we start to uncover professional digital camera's mysterious veil.
Generally speaking, common thousands of yuan of a digital camera all can be civil level, professional level price little criterion tens of thousands of yuan, criterion ten yuan, hundreds of thousands of dollars. So, professional and civil digital camera casio np-40 battery exactly where the difference?
First we answer about professional digital camera that a few problem:
Pixel is not professional or not sign. At present, SONY DSC-F707, Nikon COOLPIX5000 such digital camera has 5 million pixels of CCD, but they are real non-professional digital camera (i.e. amateurs digital camera casio np-60 battery), and journalists favorite Nikon DIH, its pixel number only about 2.7 million, but real professional digital camera.
Weight can be roughly as the difference between major and civil standards, but is not entirely accurate. We all know, professional digital camera must have many powerful function, the components must also many, these factors will lead to camera weight increase, so the professional digital camera the average weight more than absolute civil digital camera casio np-100 battery, but to 1 kg to delimit limits is not entirely accurate.
Basically can put 10000 yuan as a professional and civil price watershed. Anything with the professional two characters, the price is too high MeiPu, and civil digital camera is for the general public users of the design, not very high price nature.
But these are not touched article professional digital camera Casio QV-3EX battery, the essence of only stay in professional digital camera some sacrifices to the surface, to truly understand digital camera professional and civil distinction, still need to be deeply understand some internal things.

Famous photographers to teach you how to weak light make good pictures
British photographer Harry Benson in the past 50 years has been the signs of The Times of the record in 1963, the assassination of John f. Kennedy, 1964 Beatles us debut, every President since Eisenhower portrait of the... A variety of experience for Harry Benson bring rich shooting CANON NB-9L Battery experience and experience, for how in low light conditions make good pictures, he also has a unique insights.
Q: in low light environment, you met the most difficult conditions is taken?
A: Kennedy assassination, I still think of the scene, someone screaming, the whole situation in A, completely out of control, when almost no any light, but you don't have the opportunity to use CANON NB-8L Battery flash. Eventually people see the picture show was indeed chaos, crazy scene. Sometimes I want to, if there is a digital camera, if I can do it better.
Q: you used to camera Settings is?
A: aperture priority and manual, I do not use A high GanGuangDu, highest do not exceed 1000, of course, except special circumstances.
Q: do you use af or manual focus?
A: look. If it was in the low light environment, manual focus may be unreliable, because want to wait a long time for the upper energizer to. I just started taking photos, the camera CANON NB-7L Battery is not distance measuring system, so I'll have to estimate coke, I'm good at doing this. Sometimes I'll use automatic focus, but if photographs important scene or person, still can choose manual focus.
Q: for you, pat film and digital have what differentiation?
A: use filmed, the final result is uncertain. In the weak light, the photos were completed, I will first rushed out of small kind, and then forced to blunt a few files decision. Generally I rushed out of eight or so of photograph CANON NB-6L Battery, from bad judgment. Digital advantage lies in, you can more to deepen the idea, and not too much getting entangled in technical details.
Q: give us a your private advice?
A: don't be afraid, your picture will bring A surprise to you. Make sure you take the characters to a light on his face, and then let go to shoot it. Digital Camera Battery to the processing power of weak light impress me, it can even catch you can't see the field.
Harry Benson, born in 1929 in Glasgow, works in the life ", "vanity fair", "the New Yorker" and "the character of the album published the 50 Years in Pictures", "Photograhs of the Beatles", the 2006 Scottish news cinematography lifetime achievement award, in 2009, was awarded the medal of the British empire.CANON NB-5L Battery

Little skill to solve infinity focus run focal problem
Have a friend not shooting, sony np-fh70 battery careful examination didn't know because lens run by the coke, feel chagrin, he to video friends about, there are others who met this kind of situation, to his Labour.
I will he photographed all the photos by zhang repeatedly view, finally understand the problem: originally, ran the pictures are the focal cloud scenery, mountain view and cloud and run focal phenomenon is relatively serious. And other video friends after contact, I get reply is the situation. It reminds me of some time ago to filming the locale, check back photos, and found that the release of the dry ice manufacture film white mist effect the photograph also appeared to run coke.
The data access after that, some of the SONY Camcorder Battery is double $focal way, in the filming site have clouds and dry ice fog, possibly for the camera can't identify and appear focus error, appear run focal phenomenon. Therefore, in the cloud scenery or have taken stage of release of the dry ice white mist, to ensure accurate and focus take the result, suggest using manual focus.
Then tell everyone a manual focus small doohickey. Fixed-focus camera focus of infinity is easy to adjust, zoom head a little trickier. Specific operation is, first the camera zoom ring tone infinity, and then off slightly (about 2-3 degrees or so, press it probably is the length of the 3-4 mm), so it can realize accurate infinity focus. At this time the photo is the most clear, this is the characteristics of the zoom lens. In addition, in the shooting scene photo, especially at first light and the going down of the sun, had better use manual focus, and more will be to shoot a few pieces, to ensure the quality of the shooting.
The focusing ring back 2-3 degrees (the approximate length is 3-4 mm), sometimes get the best effect infinity focus.sony np-qm91d battery

T stage photography skills
How to shooting T stage show, T stage of the source of the canon camera batteries light complex, intensity of illumination, colour temperature is in at any time change; Model go fast machine, a stop time short; Shooting regional Co., LTD, which was filming a fashion show and model have brought some difficult game. Practical experience shows that want to shoot a good T stage performance, prepare for good equipment, familiar with the light, improve the shutter speed, found that beautiful modelling, capture the beautiful moments.
Prepare equipment, to ensure that clear of two best to prepare for the SLR cameras canon eos kiss x4 battery, a 8 million to 16 million pixels digital body and a film fuselage. A fuselage with 28-135 mm lens, the other with a 70-200 mm lens, such paparazzi rise compare with ease. If use black white film, can choose to iso or 800 professional SLR cameras. Filming use as far as possible big aperture, this can improve the shutter speed, avoid fuzzy.
Use two kinds of eye observation is photographed the best moment, through the observation in different style of dress model, the individual character that model, selective capture valuable moment, so that readers in the appreciation of picture, see the photographer, is a unique art wisdom and keen observation judgment. Because of shooting fashion show and model between news photography and is game art photography between the photography canon digital ixus 750 battery classes, and we need a good photographer, the artistic accomplishment will have a keen sense of the news. During the filming of observation, frequently do frequently shooting, think much, can make the out of the good works.
Due to the needs of the show, with music beat and stage design art effect, light intensity of illumination fickleness, exposure to ensure accurate, and can be the camera in advance in aperture priority, the aperture in maximum. In filming, camera shutter will with the intensity of illumination automatic adjustment, so take down images. If the light is dark, the shutter speed is low, will improve the GanGuangDu camera to iso or 800, it is necessary canon digital ixus 850 is battery to also can be raised to ISO1600 (but generally with the ISO1600 clap out images of particles is very thick, the color saturation and transparency have certain down)

Digital SLR how-to tutorials-aperture
Digital camera aperture is another very important physical parts, digital camera is still camera, again good lens if no good aperture also won't have the ideal effect, with advanced camera JVC GR-D270 Battery loaded on the lower film also won't produce good photos as is the same way.
Aperture are usually located in the central of lens, it is a ring, can control round hole opening size, control the brightness of the jvc gr-dvm70 battery light exposure. When need a lot of light for exposure, will aperture round hole up; If need only a light exposure, will round hole reducing, let a small amount of light to enter.
Aperture in a scene by installed in the leaf blade control, and the blade is moving. The greater the aperture and lens of the blade in the open. The so-called "maximum aperture", it is no action leaves, let the light can be shot through all came in the full open aperture. And the smaller aperture, leaf is JVC GR-D63 Battery the contraction of the complete harm, finally be narrowed down to a small dot.
The function of the aperture is like our human eyes Ma rainbow, is used to control the filming, unit of time into the amount of light, general with f / 5, F5 or 1:5 to mark. Based on the actual character, smaller f value the aperture of the larger said.
The calculation of aperture we call aperture unit value (f-number) or series (f-stop). First of all, let's talk about aperture value.JVC GR-D370 Battery
The aperture of the standard value (f-number) of the Numbers are as follows:
F / 1, f / 1.4, f / 2, f / 2.8, f / 4, f / 5.6, f / 8, f / 11, f / 16, f / 22, f / 32, f / 45, f / 64
Among them, the f / 1 is the largest amount into light the aperture of the serial number, aperture of the values of the denominator, the greater the amount of light into the small. Usually general lens would use the serial jvc gr-d275us battery number of the aperture for f / 2.8 ~ f / 22, the greater the value of the lens aperture and lens diameter and the relative increase its production costs with difficulty.
Series is refers to the adjacent aperture of the values of the gap between the exposure, such as f / 8 with f / 11 between the components level, the f / 2 with f / 2.8 also differs between the level. By analogy, the f / 8 with f / 16 difference between the two level, the f / 1.4 with f / 4 is the difference between the level 3.
In the professional photography circles, sometimes jvc gr-d70u battery called for "archives" series or "case", such as f / 8 with f / 11 difference between the spy, or f / 8 with f / 16 difference between the two case.
In each class (serial number aperture) between, the amount of light behind into serial number is half of the serial number of front. For example say f / 5.6 into the amount of light only f / 4, half the JVC GR-DVF21U Battery f / 16 into light energy is also only f / 11 of the half, the serial number of the back, and into the small amount of light, and the form of the way to series is degressive.
Serial number of the aperture and the amount of light into the relationship
In addition, considering the amount of light besides, aperture size but also with the depth of field. Depth of field is object imaging, the photo (image file) of the extent of the clear. The greater the aperture of the jvc gr-df550us battery depth of field will more shallow (clear the small areas), the smaller the aperture of the depth of field can grow more (clear range is very large).
On the left is large aperture, on the right is the small aperture, can clear indication of the two pictures depth of field markedly different
Large aperture lenses are very suitable for low amount of light in the environment, because it can be in WeiLiang light environment, rip more on-site light, let we can use more rapid shutter to take photos, so that keep filming the camera's stability. But front have mentioned large aperture lenses is not easy to make, must spend more cost can obtain.
Good digital photograph according to the result of chance to film the circumstance such as automatically calculate the size of the aperture and shutter speed usually the faster the greater the aperture, in order to JVC GY-HM100U Battery ensure that there is enough light through, so also is suitable for high speed movement took the objects, such as the act of automobile, of falling water, etc. Aperture is easy to use big fast fast door.
