Make a photo sharp

Make a photo sharp

Many beginners to photography have encountered this problem, the photos taken out of the fuzzy, canvas prints imaging is not sharp enough, compared with other people's photos, there is a big gap, and still think that something is wrong with their camera. But in fact, photography is not only the art of composition and shooting, but also the basis of photography. For example, photo on canvas here are 10 Tips that can tell newbies how to take sharper photos.

1. Safe shutter

The first condition for sharpening your photos is that you can't shake them! One of the most important causes of camera shake is the slow shutter speed. Keep the safe shutter key in mind when shooting handheld, and the safe shutter calculation method is very easy, that is, U safe shutter = 1 / focal length of the lens.

For example, when I shoot with a 60mm lens, the hand-held safety shutter is 1/60 of a second. When shooting with 200mm, the hand-held safety shutter is 1/200 second, try not to slow down more than 1/200 second, or it will be easy to shake and make the picture become blurred.

But there are also those who ask, "I have a 10mm fisheye lens, but why does my hand shake at 1/10 of a second?" In theory, you can shoot at a safe shutter speed with a focal length without shaking your hand, but in fact everyone has a physical limit on how long they can hold a camera. I recommend that you do not hold the shutter slower than 1/60 of a second at any time.

2. Turn on anti-shake function

Turning on the anti-shake feature also reduces the amount of shake in your photos, resulting in sharper images. Now a lot of new lens have anti - shake function, but should pay attention to the lens shock level. For example, four levels of anti-shake are built into the lens. When shooting with 200mm, it is generally 1/200 second for the safety shutter, and with anti-shake, it can be slowed down to 1/15 second for hand holding. But remember that the anti-shake function is not omnipotent; you hold instability will also lead to the photo fuzzy, hand-held photography shutter speed is best not slower than 1/60 seconds.

Anti - shake also have extension body and lens anti - shake two. Body is the camera itself has been equipped with anti-shake function, no matter what lens is installed, no matter whether the lens has anti-shake, can rely on the body anti-shake, but not many manufacturers launched this function, so the optional space is small.

3. Maximum aperture = best photo quality?

Of course not! While a wide-aperture lens can have a shallow depth of field effect, a full-open lens will have dark corners all around it. A large aperture will give the subject a clear focus, but the edges will become loose and blurry. Yes, this may be good for portrait photography, but for landscape photography or wide-angle photography there is a problem, try to use a large aperture photography of a building, the center of the building may be clear, but next to the place appears loose, and may not be able to see at the time, back home to find the "accident" is too late.

The problem can be ameliorated by properly closing the aperture. Generally, closing the aperture at one level will make the image sharp, and the depth of field effect will not vary too much. I recommend setting the aperture to f/5.6 or f/8 for landscapes or buildings. This will sharpen the lens and will not blur the rest of the scene or blur the foreground and background. Make sure everything is in focus.

4. Minimum aperture = best photo quality?

After reading the above one, the newbies will ask U again. I will adjust the aperture to f/22 or even smaller to make the photo extremely sharp. It is very easy to make the light wave overlapping or unstable, affect the light wave path, and ultimately reduce the image quality. This phenomenon is called diffraction.

Too large aperture is not necessarily the best, too small aperture is not good, landscape or building photography, it is best to maintain the aperture between f/8Cf/11, too small aperture is easy to make the picture quality. If you don't believe t, you can try to shoot in the same environment with f/8 and f/22. The picture quality must be better with f/8 than with f/22.

Another tip: some photographers who want to get the sharpest images will choose to reduce the maximum aperture by two to three levels, for example, for a lens with a maximum aperture of f/2.8, the sharpness of the image should be between f/5.6Cf/8. However, this value is different from person to person, the best is to personally take your own experience, or take a photo after the enlargement of the picture to see, to see which aperture value has the best picture quality.

5. Filter

If the filter is not kept clean, the image will not be sharp enough and may even have a direct impact on the composition. And the quality of poor filter in light transmission, coating color quality is uneven, it is easy to appear polarized light, sharpness reduction, so that the picture is not clear sharp. Everybody newbie does not worry to spend money, a good filter can accompany you 10 years 8 years to have no problem!

For example, if you want to take sharper and bluer photos under the sun and blue sky, remember to install c-pl polarizer to reduce light refraction. In places with large light differences, such as sunset and ground environment, it is necessary to make full use of ND dimmer or GND gradient grey filter. In this way, the photos will be more vibrant colors, more in line with the novice mind out of the composition of the image.

6. Face recognition

Not all cameras are equipped with this feature, but if your new camera has face recognition, it will be much easier to focus correctly. Face recognition does not need to consider the position of the person in the photo. As long as he/she appears in any part of the photo, the camera or lens will automatically recognize the face, and the focus will automatically select the face of the nearest camera. Instead of spending time moving the focus, you can spend more time on composition and adjusting the camera Settings.

In recent years, some digital cameras and even lenses have facial recognition function, can track the human eye, but also can identify the left and right eyes. This is very useful for portrait photography because many times it is easy to focus the eyes with the full aperture open. This feature ensures accurate focus.

7. Use the focusing method flexibly

Many cameras now have at least three ways to focus, but many novices may not have noticed. Nikon, for example, has four types: af-a, af-s, af-c and MF. Canon also has One Shot, AI Focus and AI Servo modes. Knowing how to use these methods in different situations can be very helpful in taking sharp pictures.

Af-s and One Shot represent single-point focus. For example, when shooting a static object or scenery, the camera will lock the focus distance when the shutter is pressed at the back of the selected subject. The resulting picture will be clear and the rest of the scene may be blurred.

As for af-c and AI Servo, this means constant focus when the shutter is half pressed. Be aware that the camera will not give you an indication that the focus is successful. This focusing method is very useful in shooting dynamic things, such as animals and racing cars. Because a single point of focusing takes too much time, there is not enough time to change the focus, so I prefer to use af-c or AI Servo in shooting dynamic things, such as racing cars and animals.

As for the af-a or AI Focus, it is actually the combination of single point and continuous Focus, but pay attention to the way the camera can turn the Focus at any time according to the situation. This will be difficult to adjust. I would suggest that you can choose the above two methods. It is better to use af-s (One Shot) or af-c (AI Servo) in different situations.

8. The Tripod

A tripod is very important for photography because it is the most effective tool to keep the picture clear, and it is not easy to find a suitable platform for the camera and have a good composition, so a tripod will be more suitable. If you want to take pictures at night, such as the car rail, light rail photos still remain clear, it is necessary to tripod.

Some cameras now support very high sensitivity, but eventually high sensitivity will get noise, so small make up is to suggest you take more tripod, don't be afraid of hard, it will make you have unexpected effect. At the same time when long exposure to remember to close the small aperture, low ISO, but also to turn off anti - shake, avoid anti - shake parts moving and making the image fuzzy, so that your photos will naturally become sharp imaging.

The heavy foot frame unloading force is stronger, will be more stable; Carbon fiber, which has become more popular in recent years, also has a good bearing capacity, but the price will be relatively expensive. If the tripod axis hook, you can hang the camera bag and other carry-on items, more uniform discharge, reduce the picture vibration.

9. Shutter release or 2 second selfie countdown

Continue just use the secret of tripod, besides taking tripod, had better take a shutter release more, can avoid because both hands is contacted so the camera makes the photograph is blurred, and shutter release supports B shutter, the picture that needs to exceed long exposure is no problem. In addition to the shutter line, many beginners in recent years will switch to 2-second selfie countdown, first in the camera to adjust the aperture shutter ISO Settings, and then use the selfie function shooting, you can avoid a moment of shooting contact camera and make the photo vibration. However, the penultimate selfie does not support B shutter, so after the experience is recommended that we buy a shutter line is better.

There are various kinds of shutter cables available in the market, generally you can choose to connect the camera with a cable, and there are also screen and no screen, even you can add 2 seconds on the shutter line selfie is no problem, so that you can "steady", to ensure that the image sharp photos.

10. Pre-rise of reflector

For long exposure and sharp images, use the mirror-lockup feature. When the shutter is pressed for the first time, the camera will only raise the reflector and will not shoot. This method helps prevent the camera from raising the reflector when the shutter is open for exposure, causing the camera to vibrate and blur the image. Be aware, however, that the viewfinder will not be able to see the scene when the reflector is raised, so the drawing and all the Settings are done before pressing the first shutter.

Novices often ignore this feature, but it is no less important than using a tripod. This is because the vibrations raised by the mirror during shooting are enough to affect the image. Because each camera's reflector has a different pre-lift function, dye sublimation printing on aluminum the higher phase will be on the top control ring. An entry-level camera may be tucked away in the menu, so you must know its location before shooting. Combined with the above tips, the sharpness of beginner photos is no worse than that of professional photographers!
