News:

On Boxing Day, two Morecambe and Wise episodes that were lost for decades were broadcast on BBC2.  The original colour was recovered from black-and-white 16mm film prints and the resulting picture quality is very good.  I had seen previous programmes that used colour recovery but this time, somewhat belatedly, I decided to find out more about the process.  Really the topic is outside the scope of bbceng, but visitors to this website might be interested in the descriptions linked below.

Here is the background to development of the colour recovery technique.  The final system is described here and you can also read about the thought processes behind its development.  I only understand it in a fairly superficial way, but I found it fascinating and I hope you do too. The linked pages give due credit to the people involved, including Richard Russell who has contributed to bbceng.  His Transform PAL Decoder work was useful preparation for his colour recovery work and it is mentioned in Part 2 of his reminiscences.
