How to remake oil painting

Oil in oil paintings reflects easily. If it is inevitable, the remake photos will be rough and distorted. Pay attention to the following points when remaking oil paintings: 1. Stick the oil painting on the wall near the window and draw a line with a piece of white paper. 2. Fix the camera on a tripod with the lens center facing the oil painting center. Observe carefully whether there is reflection on the front. If there is a reflection, change the position of the oil painting again. 3. If you use lights, for small oil paintings, you can first aim the light at the reflector, and then use the reflector to illuminate the oil painting, which can reduce the reflection and obtain a soft effect. For large oil paintings, it is difficult for the reflector to achieve uniform light distribution, so it can be directly illuminated with light, but the reflection should be carefully observed from the front until there is no obvious reflection on the oil painting. However, for some oil paintings with thick strokes, a slight reflection can still be allowed when remaking. On the contrary, this treatment is allowed. , 30? , even 20? The smaller the angle, the weaker the reflection, but the more uneven the illumination. In order to make the light uniform, double lamps can be used to illuminate from both sides, or the distance between the lamps and the oil painting can be increased. 5. It is not advisable to use flash lighting, otherwise the influence of reflection cannot be observed. Silhouettes include silhouette of people and silhouette of scenery, with clear and eye-catching tone, concise picture and prominent theme. Silhouette photos should be taken in the morning or under yellow and wrong backlight. It can also be shot under general sunlight backlight conditions. The exposure time should be determined according to the background when shooting. Use bright parts as the background to set off the dark tones of people or things. When choosing the shooting angle, we should fully show the outline of people in the foreground. The background should set off the foreground. The outline of the foreground part cannot overlap with the dark tone of the background, otherwise the outline shapes of people and things cannot be distinguished. Affect the shooting effect. When using the sky and rosy clouds as the background to shoot silhouettes, you can add a medium yellow filter to darken the sky to highlight the rosy clouds. When developing, slightly extend the time and increase the contrast.
