Photographic homework

1. Try to use a standard lens with a focal length of 50mm or the corresponding focal length to take group photos, because the angle of view of the standard lens is basically the same as that of the human eye, and the ratio of the angle of view of the photos taken is close to the visual impression seen by the human eye. Try to avoid using wide-angle lenses, because the proportion of portraits taken before and after is too different.

2. In order to make the front and rear figures as clear as possible in the group photo, try to use a small aperture above F8.0 (the aperture above F5.6 should also be used for portable cameras) to obtain a greater depth of field. But the smaller the aperture, the better. If the aperture is too small, the image quality will be degraded. Try not to use a small aperture above F 16.

3. Set the focus slightly in front of the middle of the front row and the back row, which can ensure the clarity of the front and back rows, because the depth of field in the back is generally longer than that in the front, which can ensure that the first row and the last row are clear. Turn off the focus switch after determining the focus, so as to prevent the camera from being inaccurate when refocusing.

4. If possible, you should use a tripod and a cable release to set the camera in a continuous shooting position, and press the shutter when you shout "Ready" ... One, two ... "When you shout" Three ... ",you have already taken several photos, avoiding the phenomenon that some people close their eyes because of nervousness.

5. For outdoor shooting, it is best to avoid using 90-degree side light that causes yin and yang faces. If the light ratio is large, turning on the top light of the camera can also play a certain role in supplementing light. Pay attention to the background when measuring light. If the background is too dark, reduce the exposure, otherwise increase the exposure.

6. For a group photo with a large number of people, make good use of the steps. Stations are generally the first row to sit on stools, the second group to stand on the ground, the third row to stand on the platform or the fourth row to stand on the table. If it is not enough, arrange to squat in the front row.

7. File storage must use the best compression ratio with the largest size, and it is best to use the RAW format, because if the exposure and white balance are not accurate during shooting, there is a lot of room for later adjustment. If it is in JPG format, it is basically difficult to remedy.

Simple shooting skills:

1, taking a long focal length lens as the main shooting lens (120 camera is about 250mm lens or 135 camera is about 135 mm lens), and taking its short depth of field function.

2. According to the principle of portrait formula composition method, close-up, half-length, seven-point or full-body composition can be taken directly, about 5-8 steps away from the subject.

3. During exposure, according to the characteristics of portrait photography, the aperture compensation of 1 ~ 2 should be turned on to make the facial texture brighter. The light on people's faces is soft and bright, which is the focus of this kind of photos.

4. In order to create bright eyes, it is best to place a reflector or whiteboard in front of the portrait to make the eyes reflect bright spots.

5. When printing, it is best to follow the post-processing skills and printing soft focus treatment to completely soften the skin, so as to achieve the soft effect of the whole photo.

6. The shapes or props of the theme characters should be changed more. Otherwise, if there are too many photos, the visual focus will remain unchanged, and the shortcomings of composition, depth of field and shooting techniques will be exposed.

7. Design the modeling style of the theme portrait, choose the scene suitable for the overall performance, and do a good job in the preliminary theme and scene design.

8. Usually, we should cultivate the ability of aesthetic composition, and draw up the overall composition plan between the theme portrait and the scene when shooting. Don't fall into the stereotype of portrait formula composition, take close-ups

9. Analyze the application of lighting on the spot, fuse the main body of the portrait to be photographed by addition and subtraction, and control the outstanding performance of lighting in the scene environment without falling into the common problems of general commemorative photos.

10, control the length of depth of field, create a touching and advanced depth of field performance, and don't fall into the messy mode of ordinary life photos.

1 1. Choose the most suitable photo opportunity to press the shutter, grasp the vitality of the portrait and the artistic sense of the scene, and take a perfect portrait with scenery.
