referring to that certain coloring of older photos.
From the tutorials on that page, it appears to be simply a case of curves processing on each channel separately. As IM is not interactive, you will have to play some with things like -level, +level, -sigmoidal-contrast, -gamma etc on each channel to get the effect you want.
I also have a curves script, but it does not allow direct manipulation of each channel. So one would have to separate channels, process independently with the script, then recombine the modified channels.

Re: Cross process / retro settings..
If you apply a complex cross-process on a "HALD" image
You can the re-apply the same process quickly to any other image

Re: Cross process / retro settings..
Would you care to submit your HALD image and perhaps the process you used to create it?
or perhaps you have your own website with the info
