How can ability clap a sharp clear pics
Play a period of time for photography, along with the appreciation ability and a photo to demand more and more, usually will ask a question: what can make sharp clear pics? His pictures out 1:00 also not clear, look like paintings as…
In fact the human eye is through the edge of the resolution object to determine its sharp or not. So many people will mistake the high sharpness of photograph, mistakenly think that is high resolution. This is actually caused by human visual cells of illusion. In fact, digital photography is to belong to high sharpness, low resolution photos. While the traditional film is high resolution, low sharpness photos. Generally speaking, sharp clear involves three main factors, it is respectively lens, film (or sensitive components) and personal technology. Lens and a photographic component part here we don’t talk about, say first artificial hypothesis to influence the photos of sharp clarity. Here are a few tips.
1. Use a tripod
Many people think the camera to take up with a steady hand, photo in the computer see all are hazy. Don’t be confused by the sun and despise hand shake! Even if is the heart of every time beating, the blood in the body will lead to shock the flow of the hand. Do not think that is talking and laughing, according to the calculated pulse can lead to about 0.2 mm of displacement, if shutter speeds slower than 1/10 seconds, you’ll have a chance to shake hands. To use the tripod words, must use high quality on a tripod. The so-called high quality tripod, it is every foot can be independent, use light quality of his alloys and easy to carry feet frame. In the wind when shooting location, the height of the tripod as low as possible, or you can use weights reinforcement on a tripod.
2. The shutter release
Do not think that the camera on the tripod with it once and for all! No matter you press the shutter action how to light, can also cause shock, use the shutter release can reduce vibration. If not the shutter release, at the very least, also use timing self-time function, let the camera decided to start the shutter ah!
3. The shutter speed/safety shutter
That is the use of feet frame, you can’t be taken that the object to be not moved. Even if you were filming the scenery as, for example, is mountains, will also happens. Once this mobile plus your hand earthquake, clap out photos will become a painting. Especially with zoom lens filming, a slight shaking sharpness will cause tremendous effect, then remember to speed up the shutter.
The focal length of the photos to you with the hand camera sony cyber-shot dsc-m2 battery photo has a direct impact on the clarity of the. In a long-focal-length, in order to make photographs don’t hand blurred by shock effect, the photographer’s exposure in a short time. That how to calculate the safety of the hand not shock range? General photographer would “1 divided by the focal length” to calculate. For example is 35 mm camera, the shutter speed should be at 1/35 SEC above, the 200 mm? That at least 1/200 of a second, it’s not your picture will have a great chance fuzzy. To remember that these was only about the guidelines, of course, hand shake level is different from person to person!
4. Focus accurately
A very important but often neglected problems. Some wear glasses photographers have found that wear don’t wear glasses of focusing accuracy are very different. Don’t be too quick to press the shutter.
5. Use the best aperture
A lens aperture all the resolution of the gap is great, have time 12 aperture, sharpness as big difference! Generally speaking f8 and f11 is “best aperture”, its resolution and sharpness is very close. Sometimes, with us f16 and f22 such aperture shooting, depth of field large but may make the resolution down, this is because the diffraction phenomenon ACTS.
6. Diffraction
The so-called diffraction, is when the light through the aperture, close to the edge of the aperture leaves light, can produce migration; And close to the optical axis light, then go straight to converge on focus. If the sony cyber-shot dsc-l1 battery aperture is very small, so the diffraction phenomenon will become very serious. Many scenes on the f22 to f32, the resolution will drop as many us f16 than.
7. The camera lens
The author also knows that this is bullshit…… This is an old story, and price is 10000 yuan or a lens, and the price is 600 yuan a lens: what’s the difference? But now many scenes with super computer manufacturer has deduced the advanced optical formula, won the excellent optical design, and these lens of imaging sharpness is very high, but cheaper helps!
