I have this old diapositive slide of a tram taken at dusk by my father. I have later scanned the slide (the image is reduced in resolution for this upload).
As I still have the slide, I can scan it again.
What can I do to improve the quality of the resulting image?
Not only during scanning but also in post-production. Can I do something to clean the slide without damaging it before scanning?
I would like it to appear lighter (but still dusky) and the colours should be fuller.
I have a HP Photosmart C7180 and a Brother MFC-J4620DW to work with for scanning.
The plan is to have it blown up to around A4 and give my dad a print for his 85th later this year.
