Nikon d7000 Usage Skills _ Kony Portrait Photography Photometry Skills

Backlight is often used to shoot portraits. In order not to overexpose the highlights, spot metering is adopted, and the metering point is in the middle of the face. Because it is in the transition area between the brightest point and the darkest point (usually called the gray area), I always press the shutter half-way when focusing to ensure the clarity, and I never use the flash to fill the light when taking portraits, because I think that if I use the flash to fill the light under the backlight condition, the figure will be leveled and there will be no three-dimensional effect! When shooting, increase or decrease the exposure compensation according to the light condition to achieve the best shooting effect!

Most digital cameras have a little metering mode, and the measuring range is small. It's not easy to master it directly, so I only use it for photometric operation.

Photometric operation

1. Starting the metering system is consistent with starting the viewfinder. Just press the shutter (that is, half of the shutter position, just press it once, no need to hold it. If you keep it, you will start the focusing system, but you don't need to focus for metering). At this time, the shutter, aperture, viewfinder can take photos and other indicators appear, and the metering system has been started. The metering is turned off for 6 seconds by default (I can set it to 6 seconds). Similarly, we can judge whether the metering system is on or not from the viewfinder indication.

2. When the metering system is turned on (a period of time after half pressing), the exposure can be locked at any time through ae; You can also directly perform other operations while the metering system is turned on (note that it is not necessary to press the shutter half-way before locking the exposure, as most people say). Is there a sign of locking exposure in the viewfinder display? *? Sign. However, it should be noted that when the mode dial is in the gear position, all gears can be locked except B and X gears (guess what happens after M gears are locked? Hehe, the M file has become the P file. To put it bluntly, after you measure light, when the shooting mode is set to M file during the period when the metering system is turned on (6 seconds), the data of M file is only measured data (convenient). Then increase or decrease the exposure (moving the aperture value or moving the shutter value) within the range of m to change the EV value of the exposure. You can select multi-division, center focus and spot metering modes through the metering mode lever, and whichever metering mode is based on the center point of the viewfinder.

3. Spot metering is a good way to ensure the correct exposure of the main part, such as portrait face exposure. To correct what a friend said, it is not necessary to be close to the face when measuring, only for machines without measuring mode. Just aim the center point at the portrait face and lock the exposure, which is the advantage of spot measurement. Of course, if the photometry target is too small, we can consider close lock exposure to obtain the correct exposure value.

4. After locking the exposure (M file), you can concentrate on composition shooting. Usually, I prefer to focus on people's eyes (keep the shutter half pressed to ensure clarity) and take pictures of composition (keep the shutter half pressed), because I often only use the single-point central focus mode, and you can't know where it is in the multi-point focus mode.

5. A careful friend can see that when you take a portrait, you seem to use the M file. By the way, the metering point for taking portraits must be the point you want. What I just introduced above is the method of measuring light (spot measuring) with digital camera, and how to switch to M quickly after measuring. It's much more convenient than described in the textbook (record the data after the exam, go to M and put the measured data ...)!

6. If you don't do this, shoot directly with spot metering and measure the spot (center) at the focus (center). It's dark to the eyes (Han people), and the exposure is about to pass! Now, let's turn the metering (surface) to the M file first. Photometry has been locked in M position, and it has nothing to do with photometry when focusing and recomposing. Therefore, we use the photometry of the face and the focusing of the eyes to get what we need, and it is easy to take good photos.

Note: The above methods are applicable to Nikon cameras. When the Canon camera switches to M gear, only the last manual gear setting data is kept. But Canon cameras have the function of locking exposure. Just press it? *? Exposure lock, you can focus on shooting composition.

Nikon's product controversy

The Nikon D600 camera with a price of 10,000 yuan was actually discovered by users, and the photos taken had many black spots. After repeated repairs, the black spots still follow. Lawyers question that this is simply a product defect! However, Nikon refused to return the goods many times, blaming the smog and even asking users not to face up when taking pictures. But in the United States, consumers can directly replace the new model for free.

201April March 15, one hour after the Nikon D600 problem was exposed, the product was quickly removed from the shelves in JD.COM Mall and Tmall Mall overnight, and Suning.cn was out of stock.

Not only in China, but also in Europe and America, many Nikon D600 users have encountered the same black spot problem. However, some American consumers got the service of replacing D600 with D6 10 for free. However, Nikon did not give a clear standard for consumers to enjoy this upgrade service.

Subsequent development

20 14 CCTV 3 15 what was exposed at the party? Black spot door? Nikon China 2014 On the afternoon of March, 2004 16, he told Xinmin. At present, it is impossible to determine whether this camera has quality problems. However, the Shanghai Municipal Administration of Industry and Commerce has asked Nikon to remove D600 SLR cameras nationwide.

In Nikon Imaging Instrument Sales (China) Co., Ltd. in Tibet Middle Road, the employees of the company have returned to work after the weekend, and the telephone at the front desk of the company has been ringing.

Hu, senior manager of Nikon's China market headquarters, said that this was caused by the structure and individual differences of SLR cameras. He has contacted the Tokyo headquarters, and it is not yet possible to simply determine whether it is a quality problem.

Previously, when the staff of some special maintenance stations of Nikon explained black spots to consumers, they attributed them to? Hazy weather? In this regard, Hu said that these remarks cannot represent the company's point of view, and there is no causal relationship between black spots and the environment.

Shanghai Industrial and Commercial Bureau, right? Black spot door? Further investigation has been made, and Nikon China has been asked to take measures to remove the D600 sold nationwide. The reporter also confirmed this information from Nikon China. The reporter learned from the industrial and commercial department that after preliminary understanding, Nikon D600 cameras have sold 48,000 sets in Chinese mainland, ranging from 20 13 to 10, and 300 cameras will be received nationwide every month. 400 Nikon D600 maintenance list, of which 70%? 80% involves parts maintenance and replacement.

For the existing D600 users in China, Hu said that the problem of black spots can be solved by cleaning and replacing shutter parts. If it can't be solved completely, it will be solved according to the country? Three packs? It is stipulated that users can replace the same camera for free, and similar problems will not occur.
