Summary and supplement of key points of watchmaking
2. It is forbidden to use automatic color standard and automatic contrast instruction in later plate processing. Automatic programs can be used appropriately after merging layers.
3. The film shooting of the long scroll gallery should adopt the method of erecting horizontal guide rails or controlling the distance between the point and the focal plane (draw the position line, the triangular position of the tripod and the lighting in advance, and keep the camera angle fixed). The lighting lamp with adjusted lighting angle should move with the guide rail and the aircraft. If you use flash lighting, you must also pay attention to sufficient charging time after each flash to ensure the consistency of each flash.
4. The practice of film stitching proves that even if the dark corner of halo is not visible visually, there is still obvious difference between light and shade at the seam when stitching the lens, and PS freehand processing tools should be used to "fade" or "reduce talk" and rubbing tools for detailed treatment. It should be noted that sometimes the "vignetting removal" of PS automatic film stitching will go wrong, and two photos with the same exposure parameters will be miscalculated as different parameter values, resulting in great contrast between bright and white sky. In this case, the "vignetting elimination" check option of automatic film stitching should be turned off decisively.
5. Don't come to the conclusion that documentaries and dynamic photos of scenes can't be spliced by imagination. The practice of this post proves that it can be spliced completely!
6. The analysis and calculation of PS automatic splicing of large deformation film with wide-angle shooting are thoughtful and staggered. On the contrary, if all the films shot by the medium telephoto lens with small deformation are introduced and processed together, PS automatic stitching is only a rough connection shaping, and the connection of multiple films is a straight line with a little dislocation. In this case, first of all, we should do serious manual crosscutting and plastic correction for the misplaced lens. The second is to automatically splice multiple pieces, three pieces are a local combination, and finally automatically splice multiple local splicing combinations until a super giant is spliced. In this way, the software can calculate the mutual connection of multiple local mosaic photos according to the staggered path, and carry out seamless mosaic.
7. When shooting a bird's eye view of a large scene, a polarizer should be used to eliminate the influence of fog refraction on the overall resolution.
