Cheap (Very cheap S/H) flat bed photo scanners made by Epson can give good results at web size. They can offer a fun alternative of shooting with your old film cameras and bring new life to any old negatives you have.
These examples were scanned with a very cheap Epson 2480, available S/H for about £10-20. I would not recommend this option if you want good prints.
A really old one. I took this in 1969 with my Pentax SL (which I still have and it works perfectly) It is one of my oldest negatives as I lost many over the years
