$dstimg = ($srcimg -replace "sourcefile", "targetfile") Be sure to make the following changes to the final HSB values before putting them into the command line:įinally, the convert statement can be embedded within a PowerShell script for automated batch processing of all files within a folder: It’s important to note that ImageMagick uses different values for the HSB transform than Photoshop. With the final HSB transform values, the following ImageMagick command can apply the transform to each image.Ĭonvert "SourceImage" -set option:modulate:colorspace hsb -modulate "B,S,H" "DestinationImage"

Saturation starting point: (S new/S old-1)*100.

Brightness starting point: (B new/B old-1)*100.

The Saturation and Brightness sliders will need to be adjusted manually to find the ideal conversion, however a good starting point is as follows:.

The Hue adjustment is generally H new-H old.

Starting with the old image, find the values of the HSB transform that will result in the color match to the new image:.

Create “Hue/Saturation” Adjustment Layers over each half of the image.

Using the Point-sample tool, change the Sample Size to the maximum and find the average HSB values of each half of the image.

Create a new composite image with the two images (before and after) side-by-side.

Open both the original image and the target color in Photoshop.

Since the color transformation will work on color averages, the average HSB value of both images must be computed to find the target transform. This can be done in Photoshop or most major graphics editing software. The first step to leveraging ImageMagick to change photo color is to find the HSB (Hue, Saturation, and Brightness) values that will be applied to each image.

With the ability to process over 200 file formats and perform a large variety of graphics operations, the toolset makes powerful image processing free for public use. Ported to a large variety of architectures and platforms, ImageMagick is compatible with most web frameworks and works on the majority of operating systems.

Originally developed by a DuPont computer science researcher in the late 1980’s, the software has grown in scope throughout the years to become one of the most powerful and popular graphics processing libraries. ImageMagick is one of the gems of the Open Source world. By leveraging a command-line program called ImageMagick, most batch photo operations can be scripted for automated processing. Instead of performing the operations manually in Photoshop, the computer can often be used to automatically do the work through batch scripting. In graphics applications, it is occasionally necessary to perform the same operation on a large number of files.
