Colour B&W pics with AI
Unmesh Dinda (he's from India) over at PIXimperfect has just posted this interesting piece about an online B&W colouring website http://palette.fm/ http://youtu.be/PO9nv2f0oEw Although you pay for the full resolution coloured image Unmesh shows the very easy Photoshop way to get the final image without cost. I tried it out on a shot that you have all seen before of me and my doggy, Rags. The top image is the original, followed by the de-saturated version and then the image as seen by Pallette. The results are not as good as doing an entire colourisation by hand in Photoshop and some of the colours are not accurate but it has made a reasonable job of it.

Re: Colour B&W pics with AI
Many of the colours which are less accurate are colours which no intelligence, artificial or otherwise, could know and can only blind guess. Such as your trouser and shirt colour, the housecoat or towel hanging over the bush in the background. Personally I am not very interested in colouring B/W as it has a character of it's own. However I do think that using this kind of treatment to re-colour old colour photos that have faded and colour shifted badly, either directly or by desaturating and starting fresh, is interesting. I believe that Vibeke has tried this with some success. _________________ The subtlety and conviction of any Photoshop effect is invariably inversely proportional to the number of knobs on it ....... |

Re: Colour B&W pics with AI
As David said it is impossibel for the software to know what the original colours were but accurate realism is not what this is all about. I wondered whta the result would be if I used one of my infrared images so I ran this shot of Half Dome in Yosemite through the process for your thoughts  _________________ If at first you don't succeed then skydiving is not for you. |

Re: Colour B&W pics with AI
Having tried Pallette.fm with an infrared image I wondered what a marble statue might look like so I sourceddd this image of Michaelangelo's David. I ran the B&W image through Pallette and chose the 'Ambient Historic' preset. I opened both the B&W image and the Pallette image and processed them. It looked pretty good but I copied the Pallette image and changed the blend mode to Multiply and rreduced opacity to 35% to get the final result.  _________________ If at first you don't succeed then skydiving is not for you. |

Re: Colour B&W pics with AI
The image has turned out slightly too dark but that can be adjusted in Photoshop and, of course, you can mask out the background on the multiply layer to lighten that up..

Interesting that the Ai didn't try to force the leaves to some shade of green... |

Presuming that it's smart enough to know that they are leaves it is odd. I agree. _________________ The subtlety and conviction of any Photoshop effect is invariably inversely proportional to the number of knobs on it ....... |
