If you have negatives, get a special negative scanner. I have an old (2001?) Canon SCSI scanner. That's your best method. Then color-correct the resulting images with GIMP or Photoshop. If you only have prints, scan them at high resolution on a flatbed scanner. Then color-correct the resulting images with GIMP or Photoshop. Both of these methods are slow. But it's a one-off job. Once it's done, it's done.
