Many thanks for the kind words...really appreciated.
Bob, we sold these shops but I have my own business which is purely property/real estate....I buy and let.
Doug...for the colours I used a new layer set to colour mode for each but I wanted to do, hand painted and then applied a hue/saturation adjustment layer to each coloured layer to change/adjust colours etc.
Hope that helps.
Thanks, Ray. Just to be clear, you used a separate layer for each color you added? That is (potentially) a lot of layers. I have done some (more modest than your example) colorizing of some old photos. I followed a similar path but used selections to isolate areas for painting and HSL adjustments.
When I have done this I have always used multiple layers, with each layer having a mask for the area it deals with. This gives enormous flexibility and allows one to change the effect for each layer as one sees the result with other adjacent layers. One can sample the colours from other photographs, to improve authentiticy. I have certainly had 20 or 30 layers, with names like "under chin", "nose", and so on. Having lots of layers works perfectly. Of course the machine must have plenty of memory.
yes Doug...a seperate layer for each bit. I did one the other day and realised the image I was working on was a very large original and noticed my pc slowing a little (quad core and 8GB ram) and realised the file was 700MB plus!!! Stacks of layers and adjustment layers etc...So I had to reduce the image size....
Anyway, as Richard says, it does give total control and flexibility...
