Re: Fred's ImageMagick Curves script to duplicate PS curves

Fred, so that last point is the 250,255. I set this as the max, but I also tried setting a max of 255,255 and then adding the plot point 250,255. There wasn't much of a difference when making this change though. Other then that it should match up in terms of breakpoints. Want me to post the PS prese...

Re: Fred's ImageMagick Curves script to duplicate PS curves

Hi Fred, sure below is the screenshot of the preset I was using in PS. Does this help? I didn't know enough about the options panel to make changes within PS. Regarding the plot points I was using the combined curve of all RGB. I tried including 255 but I wasn't sure it was necessary when you note t...

Re: Fred's ImageMagick Curves script to duplicate PS curves

I checked in PS within the color settings it is set to sRBG for the image I'm testing with. Also on save it retains sRGB. The -hald-clut method you mentioned totally solves my problem! The resulting image is just about spot on the same as when I process it within photoshop using the curves preset. I...

Re: Fred's ImageMagick Curves script to duplicate PS curves

Thanks for the fast response and for the useful scripts! I'm working through all of the items you listed. It seems to work better using 0-255 then when I attempted 0-100. I also attempted to add those endpoints in PS but it doesn't make a significant change since it allows the ends to not be at 0,0 ...

Fred's ImageMagick Curves script to duplicate PS curves

Hi all, I'm trying to use Fred's ImageMagick Curves Script to duplicate Photoshop Curves filter settings. I loaded the preset into Photoshop and wrote down the x/y pairs of the light (0-255) settings of the RGB combined curve. I've attempt it on the image below. It doesn't seem to match exactly. Is ...
