B&W Colourisation
This is a B&W 70year old 4inch photo which I scanned and imported into Adobe Photoshop CS, tweaked the pixels, removed marks and scratches, and colourised the skin tones, eyes and lips, dress, neck lass and watch, tie, background, etc....
I also printed the final image to 2.5 times the original without any noticeable loss of quality.
The same process would only cost you $55 including a A4 print, and copy of image on floppy disk.
