What do you mean, a photo copy?

There are two kinds of photo copying, one is to copy the film, so that the image obtained is clearer, and the other is to copy the old photos, which has a poor corresponding effect.

There is a kind of pirated photos called old photos (usually black and white photos), which were made by photographers in the same year or shortly after shooting. An old photo is more valuable than a modern one.

The photographic paper used to develop these photos is now gone. Old photos of famous photographers are rare, so they are more valuable, especially those with signatures. After the photographer's death, his relatives and descendants are likely to continue to make modern versions of old photos.

Specifications will be expressed in inches, which is different from the diagonal length of products such as monitors. "A few inches" in the photo refers to the length of inches on the long side of the photo.

For example, a 6-inch photo is a 6×4-inch photo. There is also a commonly used method to indicate the size of a photo in the world, which is to take the integer value of the short side of the photo and add the letter R to indicate it. For example, a 6-inch photo, the specification is 6×4 inches, which is 4R.

In addition, regardless of the number of pixels in a digital film, we only look at the number of pixels on the long side. 1200 is 5 inches, 1400 is 6 inches, 1700 is 7 inches, and so on ... 1 inch (in inches) =2.54cm.

When we say x inches, we mean the long side of the photo. For example, 5 inches means the photo is 2.54x5= 12.7cm, 12 inches means 2.54x 12=30.5cm, and 8x 12 means the long side is 2.54x12 = 30.5cm. ..
