Skills of using Samsung nx3000
1. Exposure: What are aperture, shutter speed and ISO? How to control exposure parameters?
Aperture controls the amount of light entering, and the formats are F 1/2.8 and F 1/8. The smaller the number, the greater the amount of light and the brighter the picture. The amount of light entering is inversely proportional to the square of the aperture value. For example, the amount of light entering F4 is four times that of F8.
Because in photography, every time you increase exposure, the amount of light you enter will double, so the standard aperture level is:
F 1.4，F2，F2.8，F4，F5.6，F8，F 1，F 16
Every two are one gear apart, and the maximum aperture is on the far left.
Aperture not only affects the amount of light, but also affects the depth of field. The larger the aperture, the shallower the depth of field, that is, the shallower the clear part of the picture and the more blurred the background. We often see photos with empty background and clear subject on the Internet, all of which are taken with large aperture.
Generally speaking, we use a large aperture to shoot portraits and still lives, so as to achieve the effect of highlighting the subject. At the same time, shoot the scenery with a relatively small aperture, such as F8, so that all parts of the photo are clear. Moreover, the general lens reaches the best aperture at the position of two to three times the maximum aperture value, with the highest definition and the clearest picture. For example, a shot of 18-55/3.5-5.6 is usually shot at around F8-F 1 1. The shutter controls the exposure time, and the formats are 1/2000s, 1/50s, and 0.5s, so that the first exposure time is the shortest and the last exposure time is the longest. When the shutter time doubles, the amount of light entering doubles. The standard shutter level is:
1/4000， 1/2000， 1/ 1000， 1/500， 1/250， 1/ 120， 1/60， 1/30， 1/30， 1/ 15，65438
On the far left is the smallest shutter.
The faster the shutter speed, the shorter the capture moment. Then the less the subject moves in this short period of time, the more difficult it is to record the jitter of the person holding the camera. There is a so-called safety shutter in photography, that is, as long as the shutter speed is higher than this value, the picture will not paste. This value is the reciprocal of the equivalent focal length. For example, if the focal length of the lens on d5 100 is adjusted to 35mm and the equivalent focal length is 52mm, then the value of the safety shutter is 1/50s. If it is higher than this value, such as 1/30s, it is easy to burn out. If the camera or lens has anti-shake function, it can be downgraded by 2-5 levels. For example, the anti-shake of a 55-200VR lens is almost 4 gears, so when the focal length is 200mm, the equivalent focal length is 300mm, and the anti-shake safety shutter is 1/250s does not open. This shutter speed is usually too dark when shooting indoors or at night. However, if the lens is turned on for anti-shake, the shutter speed can be lowered to115s, which can meet the needs of most dark shooting.
If you shoot a child, because the child is always moving, the shutter often has to be lowered below11000 s before you can shoot a child with stickers. If it is a high-speed movement, such as hurdles, or if you want to shoot the feeling of splashing water, the shutter speed should be reduced to1/8000 s.
Sometimes a slow shutter is used, such as shooting waterfalls, clouds or night scenes. In order to shoot a dreamy feeling, you can set the shutter to about 30 seconds to shoot, so that the actions within 30 seconds are superimposed.
2, clever use of white balance and color temperature settings
There is a white balance setting in the camera, and some even have a color temperature K setting. The lower the color temperature value is set, the higher the actual color temperature after white balance compensation, and the bluer and colder it feels. On the contrary, it is yellow and warm. Generally, shooting snow scenes and snow-capped mountains is usually set at a low K value (such as 2500k). When shooting a sunset, autumn scenery usually uses a high K setting (such as 7000k).
If the entry camera does not have the function of setting the color temperature K value, you can use cloudy shadows instead of the high K value setting, and use incandescent lamp mode to lower the K value setting.
1. What is the ratio of Samsung nx3000 to entry-level SLR?
It is definitely better than the entry-level SLR in image quality, but it is excellent in ease of use.
NX3000 seems to have changed its design style and looks more retro, similar to the NX300 released before. From the point of view of color matching, Samsung has arranged three body colors for it this time, black, white and brown, with more choices.
In terms of performance configuration, it uses a 3-inch 460,000-point reversible LCD screen on the back of the fuselage, with a maximum flip angle of 1.80 degrees, which is convenient for taking multiple selfies. The core image shooting system includes an APS-C CMOS sensor with 20.3 million pixels, the sensitivity range is ISO 100-25600, and the maximum continuous shooting speed is 5fps. The fuselage design can support Wi-Fi and NFC functions.
Second, how about taking blurred photos with Samsung nx3000(20-50)?
The blur effect of this lens is actually enough, and the maximum aperture is 3.5. It depends not only on the maximum aperture of your lens, but also on your shooting method. You can try to put the subject closer, adjust the focal length to the nearest end, that is, 20mm, and then open the aperture to the maximum, that is, 3.5, and put the background farther away, so that the blur effect is obvious.
Third, Samsung NX3000 evaluation trial
Recently, many designs of mirrorless cameras will more or less incorporate a trace of retro charm, and Samsung NX3000 is no exception. NX3000 maintains its original fashion features, and the whole body is wrapped in leather, which is more retro. Moreover, this machine * * * has three colors, such as white, black and brown, which can provide users with a variety of choices.
The upgrade of this camera lies in the use of 180 reversible screen, which provides more convenience for users to take selfies. In addition, there are two different shooting recognition functions, smile shooting and blink shooting, which are very popular among female users. The fly in the ointment is that the flip screen has no touch function.
Samsung NX3000 is equipped with CMOS sensor, and the effective pixel is about 20.3 million. With 16-50mm electric zoom biscuit mirror, the lightest use effect can be achieved. And 16-50mm lens is equipped with i-Function control button, through which the corresponding parameters can be adjusted.
The battery of this camera is a B740 lithium battery with a capacity of 2330mAh, which looks quite similar to the battery of Samsung mobile phone. And in order to achieve the effect of slimming, this camera uses a microSD memory card.
When the aperture of the 50mm focal section is F8, the resolution of this lens is relatively high at 50mm; Also in F22, its resolution is relatively weak. Overall, the resolution of this lens 16mm and 50mm is between 3000LW/PH and 2700LW/PH, and the focal length of 15mm and 50mm is relatively balanced.
Self-portrait has become the most popular shooting behavior of young women, and you can often see all kinds of self-portraits of friends, Weibo and friends in space. Sunbathing, taking photos and sending photos to Weibo ... Modern people like this kind of reportage entertainment. This fashion trend has sold all kinds of selfie artifacts. The upgrade of Samsung's latest entry-level mirrorless camera is to add a flip screen, which can help us achieve the perfect selfie.
It is common for girlfriends to go shopping and attend parties, and taking photos is even more essential. The advantage of 180 flip screen is that it can realize various self-portraits, and more importantly, it can leave a perfect photo for your girlfriend. The following self-portrait proofs all belong to the beauty mode in smart shooting mode.
Although Samsung nx3000 seems to be inferior to other SLR products in image quality, according to the portability of the machine and the actual user experience, the advantages of Samsung nx3000 are still very obvious. It not only has fashionable and beautiful appearance design, but also has simple function and convenient operation. For example, the use of Samsung nx3000 introduced above reflects the humanized design of the product, which also makes it win the success of both word of mouth and sales in the market.
