How to make the seal clear when shooting calligraphy and painting works

Because of the limitation of shooting site, ordinary photographers basically choose to shoot in natural light, and the flatness, wrinkle and exposure balance of their works can't be controlled. In addition, not paying attention to the correct use of equipment leads to serious problems in the perspective of the work, which brings difficulties to the later adjustment.

Strictly speaking, shooting paintings and calligraphy works must meet the following conditions:

1, there is a certain shooting distance, and the straight-line distance between the general photographer and the painting is not less than 3 meters; Under it, it is possible to travel in wide-angle deformation;

2, the digital camera is not less than 20 million pixels; The camera with too low pixel is inconvenient for the use of the work, and the space for later cropping is also very small;

3. There must be a large-area magnetic attraction board on the wall (or a large wooden board for fixing paintings and calligraphy works with thumbtacks) to facilitate the hanging and storage of paintings and calligraphy and keep them flat. If not, please have two people stick them on a white wall by hand.

Shooting point

1, the focal length is preferably controlled above 35 (converted to human eyes, it is about 35 focal length of a full-frame camera and 50 focal length of a common SLR), and it is generally between 50 and 85 to avoid deformation. I often see that the photos taken by friends turn straight into arcs, which is caused by the short focal length; If you can't shoot the whole picture at once, take the film method;

2. The exposure combination of the camera is generally a lower ISO, a smaller aperture, and the shutter speed depends on whether there is a tripod to ensure a clear picture;

3. Customize the white balance to keep the correct color;

4. Take multiple photos of the same work to prevent blurring;

5. The plane of painting and calligraphy works should be parallel to the plane of the lens, and the main axis of the lens should be aligned with the center of the painting and calligraphy picture, mainly to avoid perspective deformation;

6. Determine the level of exposure compensation according to the color depth of painting and calligraphy works. For example, shooting snow scenes or black-and-white calligraphy works, the exposure can be slightly reduced by one file to avoid overexposure.

Main points of flash shooting

The biggest advantage of using flash photography is that it is not limited by natural light conditions, and can correctly restore the color of calligraphy and painting and eliminate wrinkles. Through the practice of real shooting, even if the framed paintings and calligraphy are shot in the sun, there will be wrinkles on the surface, and flash photography can effectively eliminate these wrinkles.

1, the power of two or more flashlights is not less than 400W, so it is too small to flatten the wrinkles on calligraphy and painting, and a single lamp is easy to form an imbalance between central exposure and edge exposure;

2. Generally, the power of flashlights should be adjusted to the maximum, and the working power of more than two flashlights should be consistent to avoid uneven illumination, and the light angle should be perpendicular to the picture, so that some folds on the picture will not produce shadows;

Matters needing attention in shooting calligraphy and painting works:

1, 100% ensure that the calligraphy and painting are not deformed ~ the color reproduction is consistent with the original, which requires the camera to be completely parallel to the calligraphy and painting, and observe whether the four sides of the calligraphy and painting are deformed from the viewfinder. If it is big or small, the distance between the upper part of the lens and the calligraphy and painting is smaller than the lower part, and the left and right deformation is the same, so make sure that the camera lens and the calligraphy and painting are horizontal when shooting.

2. The lighting of calligraphy and painting requires a balanced overall light. Generally, a lamp lights at an angle of 45~50 degrees from the left and right sides. It is important to remember that each part of the painting receives the same amount of light.

3. Usually take more pictures of a painting, such as the overall picture, handwriting, seal, figures, flowers and birds, and places where lines are concentrated. In addition to the overall picture, you should generally turn on macro mode. In this case, the details are in place, and you can clearly see the seals, people's faces, birds and insects, handwriting and so on.

4. Shoot China's paintings and calligraphy with a flash, not through the glass frame; Because the reflection of Xuan paper works is weak, you can shoot with flash, but you can't shoot oil paintings with flash.

Late skill

Pre-shooting of calligraphy and painting works is the foundation, and post-editing is the core. Without strong post-production technology, it is difficult to make a perfect painting and calligraphy work.

The later process includes defect adjustment, exposure adjustment, lens perspective correction, tilt correction with straightening tool, and magnetic nail trimming with decontamination tool when entering PS.

abstract

Shooting calligraphy and painting works must meet three conditions: shooting site, shooting skills and post-adjustment technology, in order to shoot satisfactory works.

There are three requirements for calligraphy shooting:

First, the details should be detailed. The benefits of calligraphy lie in the details. Look at the details, the gestures, the rhythm, the rhythm. Pictures of calligraphy works without details are very painful to look at. In the process of shooting, whether it is a mobile phone or a SLR, a tripod must be used, and the focus of shooting must be re-shot.

Second, the light is even. Many people use mobile phones or SLR to shoot a work, which is often half bright and half dark. The reason is that there is a problem with running out of light or improper use of flash. If the computer post-processing highlights the dark part at the bottom of the work, the overall effect of the work will be distorted.

Third, it should not be distorted. Calligraphy works, no matter how many feet, are horizontal and vertical squares. If the lens is not perpendicular to the paper and the four corners are not parallel when shooting, the handwriting of the work will be somewhat distorted (which any calligrapher can't tolerate).

If this famous Tian Jie is well painted, the light and illumination in this direction are OK.

Calligraphy works must be mounted before shooting. Let's not shoot it. I have seen many famous works taken without mounting, and the effect is the same as that forged by Jianghu calligraphers on the street. There is no character at all, and everyone is very lost. It is not difficult to put on a painting heart. Calligraphers can do it themselves. Xiaoxian and Rong Baozhai's master studied it for a year, sprayed the painting heart like silk, and then flattened it with flat glass.

This kind of shooting is a common phenomenon, and it is impossible to completely transform it in the later stage.

A good picture taken by calligraphy should be clear, with uniform light, complete ink color and gas, and the lines of rice paper will not disappear. Looking at pictures is as impactful as looking at the original. When photographing calligraphy, many photographers mistakenly think that the rice paper is blank except for calligraphy, and then dig out all the blank rice paper in the later period, which is a special move to deceive people.

The blank space of rice paper is not pure white, but has a certain density, which sets off the black of calligraphy words. This is the case when calligraphy is white. When we look at the original with naked eyes, the light reflected by rice paper is not dazzling pure white, but soft and extremely light gray.

In the process of turning the blank into pure white, the black of calligraphy words is deepened invisibly, so it looks harsh and disharmonious. The author's personality has been changed. Historical calligraphy is not pure black, but ink is divided into five colors. Whoever makes calligraphy pure black should type.

Light is everything, and finding a good angle is the strongest magic weapon against light.

Speaking of this, the subject asked about his skills in shooting calligraphy works with his mobile phone. According to the above situation, Xiao Xuan summarized as follows:

Besides using a tripod, the most important thing is to use it. So the way to shoot is to use lights. Lamps can be all kinds of lights at home. All use, such as desk lamps, floor lamps, ceiling lamps and chandeliers, are all turned on. Try to walk around at work.

It's best not to shoot in the morning and evening, when the light is dim and the indoor lighting can't keep up. As an intelligent metering device, the mobile phone will be considered bright at this time, so the aperture is not large, and the shot will be gray and not too clear.

The shooting location, ordinary studio or study, the natural light is generally not very good, so cleaning a white wall and fixing the work on the wall is beneficial to the maximum verticality of the mobile phone and the work. Don't point this white wall at the window, because there will be photographers when shooting.

On the premise of not adding more light sources, you can find some solid colors like rice paper, KT board and foam board and put them opposite the main light source as reflectors. The effect of this lens is not stiff, but softer.

A good shot should be like this, with no place too bright or too dark, no loss of details, and nothing added.

In addition, after the shooting, we must carry out post-processing, trim the periphery of the work neatly, make the whole work bright, and remove some ink spots and dust that may exist on the work. The cleaner the work, the more obvious the taste. The red color of the seal also needs to be strengthened-it is not recommended to decorate it with mobile phone software, which is often distorted. To be responsible for the works honed for more than ten years, you can find a graphic center to watch them deal with them. In principle, the degree of treatment, the lighter the better.

Post-processing over shooting

For the authors of calligraphy from the media, if they often shoot their works, it is suggested to buy two electronic flashlights with large indexes, one on the left and the other on the right, and shoot with the flashlight on the mobile phone, which is better than natural light 100 times. Post-finishing also saves a lot of trouble.

Finally, if it is used to print calligraphy works, mobile phone shooting is completely useless. In addition to the quality factor, the picture size is too small. It is enough for us to look at hundreds of K pictures, but it is enough to print hundreds of megabytes of picture files. Calligraphy works, including seal cutting works, look black and white and red, but they are very particular when printing.

Even if the red color on the seal is wrongly matched, the effect is quite different. When printing a book album, the printing factory only knows the printing part, and the shooting department only knows the shooting part. It is impossible to separate them. Either the photographer knows printing or the printer knows painting and calligraphy. Printing the same calligraphy on different papers has different effects. )
