Photo samples can be kept permanently.

Different papers and different ways of preservation are all related to the length of time the photos are kept. Kodak's photographic paper is said to be 100 years colorfast (under normal temperature and humidity conditions), which means it can be preserved for more than a century. Be careful not to let strong light shine on the photos. In addition, it should not be placed in a humid place. There will be no problem with photographic paper for a century now.

Under normal circumstances, it can be stored for 8- 10 years, and it will fade after 8 years. Pay attention to avoid light, keep the photos for a longer time or in a sealed way to avoid contact with air, which can be kept for more than 70-80 years.

In addition, it takes longer to save photos on computers and other networks.
