Cross process / retro settings..

[dognose]

I'm looking for what settings would be good to create cross process style pics..

please define "cross process"! do you mean a montage? if so, see http://www.imagemagick.org/Usage/montage/

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.

If you apply a complex cross-process on a "HALD" image
You can the re-apply the same process quickly to any other image

Thanks, the HALD works great!

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

[dognose]

Sure

Code: Select all

convert original.jpg retro_colors.png -hald-clut out.jpg

I need to make some more though for different types of old film

Please continue to submit different HALD effects
