Points to note when shooting splices

1. Make a plan in advance

Make a shooting plan for the scenery to be photographed: use several pictures to connect them, and where each picture starts and ends. Pay attention to selecting a landmark scene with obvious characteristics on the edges of both sides of each piece. This scene should not be very far away and have clear outline features for easy identification when PS overlaps;

2. Pay attention to the overlapping parts

Since the edge of each element photo is inevitably slightly deformed, and generally the lens has a higher resolution in the central part, and the imaging distance is more accurate in the central part, and the distance between the edge parts is slightly It is large and the image sharpness is slightly inferior, so the higher the picture requirements, the more overlapping and overlapping parts of each element photo should be. For 6X6 frames, the overlap can be less, about 1/4, and if you are confident, you can only leave 1/5; for cameras with a length of less than 135, the overlap should generally be 1/3 to 1/4, not too little to avoid splicing later. Hard to identify;

3. Use a mid-focal-length fixed-focus lens

Because the mid-focal-length fixed-focus lens has the highest resolution and smallest distortion among all types of lenses. The minimum focal length of the lens used to shoot the film should not be shorter than 35mm. Practice has proven that the effect of using a fixed-focus lens to connect the lens is better than that of a zoom lens. When it is necessary to use a zoom lens, try to use the focal length position with the highest imaging quality. The front and rear shooting positions must be subject to the use of the focal length, and do not zoom in for convenience; because wide-angle and ultra-wide-angle perspective distortions are large, which is not conducive to subsequent film editing. The connection between;

4. When using a tripod, it is best to use a pan/tilt that can rotate horizontally

In this way, the element photos taken are at the same horizontal height. In addition, the pan/tilt has an angle scale, which makes it easy to rotate evenly at equal angles to grasp the overlap value. (Under special circumstances, it is not necessary for each picture to be taken at the same angle); and every time you turn to an angle, remember to lock the gimbal before shooting;

5. Use mirror lock-up and shutter release cable

This is also a must for landscape photography and is not a special requirement;

6. Do not zoom during the shooting process

When stitching together photos of elements with different focal lengths, a more complex size transformation is required, which is difficult to master;

7. You can manually control the focus during the shooting process

Because in a wide field of view, the visual subjects of each element are not necessarily at the same focus distance, and some may have scenes that need to be represented in the middle and near distances. If you change the angle, it will only be a distant view, and the middle and close shots will be empty, so each element piece does not have to be fixed at the same focusing distance;

8. Pay attention to the consistency of the exposure of each element piece.

This is also to make the color and contrast of each piece consistent when splicing the pieces afterwards, so as to facilitate the elimination of splicing marks. Traditional teaching materials and experience all say, "First meter the elements at all angles, take the average, and change to manual exposure." However, after repeated practice and verification, this statement needs to change. Because in a wide scene, some elements may need to change the aperture to adjust the depth of field, and the long shooting practice may cause the sunlight to change or clouds to appear. At this time, if you still hold on to the fixed exposure value, it will actually May cause splicing to fail. It's better to accurately meter the light one by one to ensure the success of each shot.

9. Pay attention to the connection time of each element piece to be the same

For splicing shooting that takes more than one day, pay attention to the connection time not to change. If the first shot is shot at 6 o'clock in the morning, the fourth shot will be taken at 2 p.m. There's something very strange about being together.

10. Pay attention to deleting scenes in a planned manner

Film lovers with certain experience can use the characteristics of splicing to delete scenes that are not conducive to composition with careful consideration. For example, if there is a very out-of-place telegraph pole in a wide mountainous landscape, you can "jump over" it after finding a connection with similar scenery nearby. Of course, you can also use PS technology to eliminate it by cropping afterwards.

In short, splicing is a technology that is easier said than done and is mainly mastered through practice. The above is just a summary of experience and lessons. You can make bold breakthroughs and innovations based on the actual situation when shooting. I would like to remind everyone that every time you are filming, it is best to "write the script" beforehand, "keep files" during the shooting, and "make summaries" afterwards. As long as you have the courage to practice and are diligent in observing other people's successful experiences, you can improve yourself in actual combat.
