Take a picture of Xiao Bai's new Nikon D7100

Answer 1

Here are some tips for using the Nikon D7100:

* * 1. Quickly switch shooting parameters **
The Nikon D7100 had U1 and U2 modes, which could save commonly used shooting parameters. By turning the mode picker, it could quickly switch to these two modes, making it convenient to quickly adjust the parameters in different shooting scenes.

* * 2. Usage of the lock-on, track-on, and focus function **
1. * * Setting Method **
- When using AF-C (continuous autofocus), if you want to set the lock tracking focus function, first click the menu button, find the small pencil custom settings menu, then select the A autofocus option, right click, find A3 (lock tracking focus), right click to set the options in detail.
2. * * Meaning of different settings **
- There were different options from short to long (such as one, two, three, four, five). If you choose a shorter setting, the focal point will change faster when the focal length changes. If you choose a longer setting, the focal point will change slower, which is more conducive to locking the subject you want to focus on. For example, if you were to focus on a person on one side of the street and there were cars on the street blocking the lens, if you chose the L5 long lock tracking, even if the cars were moving, the focus would still be locked on the person in focus. If you chose the short setting, the focus might be focused on the car instead of the person when the cars were moving. In addition, setting a longer delay time could better lock the focus point to a single person or scene; setting a short focus point would quickly switch between different scenes. It could be selected according to the purpose of shooting. For example, if you only shoot one person, you could choose long, and if you shoot a scene with many people such as a party, you could choose short. If you choose to turn it off, the focus point will change the fastest. Once there is an object between the lens and the focusing neck, the camera can quickly refocus on the object that is blocking it.

* * 3. Use of AE-L/AF-L keys (exposure lock and focus lock)**
1. * * Function example of AE-L/AF-L keys **
- For example, the monitor screen in the picture was very bright, and the keyboard next to it was very dark. First, aim at the small icon in the lower right corner of the monitor and keep pressing the shutter. Then, move the focus point to the keyboard area and press the shutter. Because the focus point and the measuring point are linked to re-measure the light, the monitor will be overexposed and may be blurred. If you use the AE-L/AF-L key, aim the focus point at the small icon in the lower right corner of the screen, press the AE-L/AF-L key, and then move the focus point to the keyboard area to shoot. The screen exposure is correct, but the keyboard area will be very dark because the exposure parameters are locked to the parameters of the screen brightness.
2. * * Setting of AE-L/AF-L keys **
- You can enter the menu-custom settings menu-f: control-f5: specify the AE-L/AF-L button: only the AE-lock, so that when the AE-L/AF-L button is pressed and held, only the exposure is locked but the focus is not locked. You can press the shutter to focus. In addition, the shutter button also had AE-L's function, but it was off by default.
3. * * Techniques in Shooting **
- In some special light and shadow photos, you can first measure the light and lock it (select a suitable exposure reference object, such as the sky next to the sun, water surface, green leaves, grass, etc., aim the middle focus of the viewfinder at the exposure reference object, and press the AE-L/AF-L button with your right thumb), then focus, compose, and shoot. If you feel that it is inconvenient to keep pressing the AE-L/AF-L button, you can also set the function to AE-lock (hold). In this way, you only need to press the AE-L/AF-L button when the light measurement is locked, and then press the unlock button after the shooting is completed.

* * 4. Setting for panoramic shooting **
1. * * M (Manual)**
- In full manual mode, the set aperture, shutter, and other parameters would not change with the change of view. The Nikon D7100 camera had a camera M and lens M. After setting it to M, the aperture and other parameters, as well as the focal length and focus of the lens, would not change with the change of view. It was suitable for panoramic shooting.
2. * * Storage format **
- The camera could save photos in both the raw and JPG format. The raw format stored a lot of information, and the error of the parameters could be adjusted later, but the storage file was large and the storage time was long. The JPG format was a compressed photo, which was small in size, good in compatibility, short in storage time, and the image quality could also meet the requirements. Nikon D7200 series (Nikon D7100 can be used as a reference) can choose to store photos in the format of raw + JPG or JPG. JPG is divided into JPG fine (1: 4 compression), JPG standard (1: 8 compression), and JPG basic (1: 16 compression). To ensure the image quality, you can generally choose to store photos in the JPG fine format.
3. * * Image Area **
- In the Nikon D7200 series camera (Nikon D7100 can be used as a reference), there is an image area option, which can be selected from the DV (24 × 16) and 1.3X (18 × 12). The 1.3X can obtain a telephoto effect without changing the lens and can record more images per second during continuous shooting, but it will make the angle of view of the photo smaller. Generally, the DV format is selected.
4. * * Image size **
- Common cameras had three options: L (large), M (medium), and S (small). For panoramic shooting, the L (large) option was generally selected to obtain a larger resolution.
5. * * Setting, optimization, and alignment **
- Nikon cameras had the option to set up an optimal alignment. There were options for standard, natural, bright, monotonous, portrait, landscape, and flat. In most cases, it was recommended to use the standard or natural option.

* * 5. Screen display to adjust shooting parameters **
1. * * Shooting mode and other adjustments **
- Press info first, and the shooting mode will appear (such as m, a speed priority, p, etc.), which can be adjusted by pressing the relevant points. For example, if the shooting mode was set to the M gear, one of the areas represented the shutter speed, and the aperture size could be adjusted by the dial (front dial).
2. * * Image quality and size adjustment **
- Pressing the plus sign on the magnifying glass, and then turning the wave wheel behind it to adjust the quality of the image. Fine was the highest quality, while Normal and Basic were lower quality. Press and hold the small S and then turn the front wheel to adjust the size of the image. L is the largest, m is the middle, and S is the smallest.
3. * * Focus mode adjustment **
- Press and hold the relevant button, and adjust the focus mode (such as AF-AC or S, etc.) by moving the rear wave wheel. You can adjust the point or area, or 3D, or AUTO.
4. * * Metering method, exposure value, white balance adjustment, etc. **
- Press and hold the corresponding button and turn the dial to adjust the measuring method (such as spot, center, and average). Pressing the plus and minus sign can adjust the exposure value (RV). White balance (DB) can be adjusted by pressing and holding the corresponding button. If it is adjusted to K, the value can be adjusted.
5. * * Iso-adjustment **
- By pressing and holding the button, the rear paddle wheel could adjust the value of the USB port. The front paddle wheel could be used to adjust the USB port or an automatic USB port. In addition, there were also related settings such as the reduction of noise, dynamic delighting, and optimization of settings.
