What if the old photo turns yellow?

If you want to get rid of the yellow of the old photo, it is impossible to get rid of the yellow of the original photo.

Photos can be finely scanned by a photo scanner and converted into digital image files, then processed into monochrome black-and-white images by post-processing software, and then re-printed or printed for renovation. But the picture information will be lost when scanning photos. You can also transfer to an expansion store, which generally has the business of renovating old photos.

The yellowing of black-and-white photos is mostly caused by insufficient development/fixing solution washing and liquid medicine remaining on the film base. This yellow photo has a sense of vicissitudes, so don't deal with it. The common reason why color photos turn yellow is that long-term exposure to strong light leads to the fading of pigments.
