Album classification
Stylistically, album pages can be roughly divided into two categories. One is folded and the other is loose-leaf. Hard-shell covers are arranged on the upper and lower sides of the folded album, and the pages connected with the hard-shell covers are repeatedly folded back and forth, and both sides of the folded album can be painted; Loose-leaf photo albums are relatively simple. Generally speaking, a single job is to frame a single page and box it.
Formally speaking. It can be divided into two categories: integrated album and blank album. Integrated picture album is a picture album with intentional painting and calligraphy first, and then mounted; A blank album is a pre-made album. It can be inferred from the historical evolution that the integrated album should be the origin and has always occupied the mainstream in history; From the perspective of contemporary development, the blank album system has become the mainstream.
The photo album has a small frame, which is like a small axis vertically and a small roll horizontally. There are also many squares, circles, ellipses, gourd waists and various shapes of detached sectors, which are assembled into a book.
