There isn’t a truly quick fully automatic method that gives high-quality restoration. For old prints, heavy automation tends to soften detail and leave images looking blurry, so the best results still come from some manual retouching.

A practical fast workflow in Photoshop is:

• adjust overall contrast first if needed
• use Dust & Scratches sparingly for minor surface defects
• clean remaining dust, scratches, and small damage with the Healing Brush
• use the Clone tool where healing doesn’t work well, especially around edges or repeated texture
• repair tears manually as needed

The Healing Brush is often the biggest time-saver once you get comfortable with it. Filters can help reduce repetitive cleanup, but they usually can’t handle every defect well on their own.

If you have a very large batch and don’t want to do the work yourself, a photo restoration/scanning service may be worth considering.
