Hi, Thanks for your interest,
These ones are all slides, mostly Kodachrome, They are stored well and are now over 20 years old, there is not a great deal of dust or marks present, a puffer brush cleaned them up well, I avoid “Dust / Image cleaning” programs as they affect the whole image,
They are scanned at 2400 DPI and cleaned up manually in Photoshop.
Mark 🙂
