How to shoot pear flowers

1, lens selection. Friends who use a SLR camera, it is best to use a medium telephoto lens with a macro of 100MM or more, which is conducive to shooting long-distance flowers, and the relative aperture is as large as possible, which can effectively blur the background and make the main flower get a good performance, such as F 1.4.

F2.8, etc. Budweiser works well. Macro lenses are quite useful. For most movie friends who use small digital, as long as they know your camera and hate using it, they can also shoot satisfactory PP. Now many movie photographers are trying to explore the more magical visual space in the field of flower photography with macro lenses, and many ordinary household DC products also have good close-up ability. First of all, macro brings us richer details and stronger texture. Secondly, the microscopic world that ordinary vision can't touch is also unobstructed in front of the macro lens. It can be said that the current macro image capture method has brought flower photography into a brand-new field.

Macro photographic lens usually has a small depth of field, which is the initial result of optical design, so the choice of focus and focusing accuracy are very important. The close-up function of small DC products is often completed by locking the lens group and using the nearest convergence point derived by light, so sometimes the light distribution in the picture is uneven. It can be said that in macro photography, the effect of adjusting the aperture on controlling the depth of field may not be obvious, but it is more effective in adjusting the photosensitive uniformity of the picture, which is very important.

When shooting, you must use macro mode and focus with telephoto end as much as possible. If there is manual mode, you can adjust the aperture to the maximum (the aperture number is the smallest, such as F3.3). ).

Shooting data: focal length 105 mm aperture: 5.6 sensitivity: automatic light; Natural light (noon, top light, strong light)

The use of medium focal length blurs the background better, and the subject can be separated, achieving the expected goal.

2. Selection of measurement methods. There are many metering methods for general cameras, such as spot measurement, center average measurement and evaluation measurement. When taking close-ups of flowers, it is better to use spot metering to measure the flowers, which is more accurate. When shooting a large scene and the light is not complicated, it is best to use evaluation photometry.

3. Increase the exposure appropriately.

Shooting pear flowers should not only show the details of flowers and the texture of leaves, but also show pear flowers as white as snow. As we know, the camera's metering is based on 18 degree gray board. When shooting a large area of white objects, if you shoot white objects without compensation, you will get gray scale. Therefore, it is necessary to appropriately increase exposure compensation. Exposure compensation is also an exposure control method, generally around 2-3 ev. If the ambient light source is dark, you can increase the exposure value (such as+1EV and +2EV) to highlight the clarity of the picture.

In the process of digital camera shooting, if you press the half shutter, a picture similar to the final effect will be displayed on the LCD screen, and all focusing and exposure will start. The exposure at this time is the exposure of the final picture. If the picture is obviously bright or dark, it means that the automatic metering accuracy of the camera has a big deviation, and exposure compensation should be forced, but sometimes the brightness displayed during shooting is different from the actual shooting result. Digital camera can browse the picture immediately after shooting, and at this time, you can see the brightness of the shot picture more accurately, and there will be no discrepancy. If the shooting result is obviously bright or dark, it is necessary to shoot again and force exposure compensation.

When the shooting environment is dark and it is necessary to increase the brightness, and the flash can't work, exposure compensation can be carried out to increase the exposure appropriately. When making exposure compensation, if the photo is too dark, the EV value should be increased. Every time the EV value increases, it is 1.0, which is equivalent to doubling the light input. If the photo is too bright, the EV value should be reduced. Every time the EV value is reduced, it is equivalent to doubling the amount of light entering. According to different cameras, the compensation interval can be adjusted in units of 1/2(0.5) or 1/3(0.3).

When the photographed white object looks gray or not white enough in the photo, it is necessary to increase the exposure, which simply means "the whiter the more". This seems to run counter to the basic principles and habits of exposure, but it is not. This is because the camera's photometry often focuses on the central subject, and the white subject will make the camera mistakenly think that the environment is very bright, so it is underexposed, which is also a common problem that most beginners are prone to make.

Step 4 use light. Generally, the photographic light used to shoot pear flowers is mainly natural light. Natural light includes front light, back light, side light (side back light and side front light), top light and scattered light. The PP taken by the front light is relatively flat and has a small contrast, which is not conducive to the performance of details. The use of side light can solve the problem of small contrast. The method of backlight and flash compensation is often used in flower shooting, which can make the petals crystal clear, but sometimes it is necessary to use flash to compensate, or directly use reflector to reflect the light to the main body. Scattered light on cloudy days is very suitable for taking pictures of flowers.

Shooting data; The light direction of the aperture F4.5 with a focal length of 200 mm is the top light for the main flower, and the contrast of the flower is large and the texture is clear.

Data; The focal length is 180mm, the aperture is F5.6, and the leaves of the backlight on the light direction side have clear texture and perform well.
