Problems related to photo remake and scanning

It is recommended to do the bottom scan as much as possible, and the quality is indeed higher than that of the remake (sometimes the gap is quite large). The remake is detrimental to the original-this is * * * learning. There was a time when remake was a helpless but only way (unlike the various means of entering the digital age now). For example, there were no more valuable or meaningful photos at that time, so we had to retake them in order to save and keep records. Therefore, the real remake is actually very rigorous! There are special remake instruments, and generally it is necessary to choose high-quality lenses, mostly fixed-focus lenses, and the focal length is generally between 50~ 135 mm (to avoid distortion affecting the original), which is very important! For unnecessary macro lenses, it depends on the situation. Macro lens refers to an image that can be focused at close range in order to obtain a larger multiple on the negative. This kind of lens is professionally divided into close-up lens, close-up focusing lens and macro lens. If you don't need to get the local details of the original, then you don't need to use a macro mirror. As for the light used up, if the remake is especially for the true color, the most important thing is to faithfully restore the true color! If there is color cast, it loses its meaning and quality. Therefore, the use of light and the control of color temperature are very particular! Artificial light is generally not suitable, because it will definitely lead to color difference. It is recommended to use scattered light from natural light, such as cloudy days and under the shade of trees. If sunlight is used, the color temperature and illumination angle will also affect the color reproduction of the original film at different illumination and different time periods.

Note: If the original photo you want to retake is smooth, you should also pay attention to avoid total reflection (specular reflection).
