If you are able to work in either Windows 10 Unix or Windows w/Cygwin, I have a bash unix shell script for which I tried to emulate Photoshop function of the same name. The results are similar but I do not claim it works perfectly to replicate Photoshop. Here I just adjust the shadow amount. Input: ...

Have you considered using MIFF format, which only ImageMagick uses. Or INLINE: format, which is base64 text. See https://imagemagick.org/Usage/files/#special_formats

Create a HALD image (in PNG output). Take it to your Photoshop and apply the same shadow highlight processing to it. Save as PNG. Bring it back to ImageMagick and apply that to your image using -hald-clut. See https://imagemagick.org/Usage/color_mods/#hald-clut

ImageMagick does not have a direct equivalent command to Photoshop shadows and highlights. So what user snibgo gave was one approach from what you asked originally. Did you try that? It seems to bring out the details in the hair as you asked. Also you said TIFF files, but the file you provided is JP...

add -verbose to your command line or -debug all and post the results here for the ImageMagick developers to see what might be wrong.

I do not think it is that simple. With PSD files, the first layer is the flattened layer from all the rest. Does the PSD files in this case have multiple layers?. Even if only one layer each, one would need to generate the flattened layer from the two images to add to the two individual layers. Can ...

MIFF can only be viewed using ImageMagick display command. How did you try to open it? It has a header that can be viewed if you open the file in a text editor. The pixel data will be gibberish in the text editor, however.

OK, you do have jpeg listed. Does this work?
If so, then everything is fine with regard to your jpg delegate and I would suggest you review your code.

What do you get from
does it list jpg or jpeg in the line for Delegates. If not, then you either have not installed libjpg where ImageMagick can find it or the llibjpg was installed faulty.

The width and height do not change. That define will tell imagemagick the size you want and it will iterate changing the quality value (compression) until it reaches that image size. But it is limited to JPG output only.

That is possible with JPG output. See -define jpeg:extent={size} at https://imagemagick.org/Usage/formats/#jpg_write

DPI only affects print size, not raster image size unless you change width and height accordingly.

My scripts only run on Unix platforms. So you would have to be using Windows 10 Unix or Windows w/Cygwin installed. Once you do that, then see my home page at my link below for installation instructions and the link to the multicrop example page. I recommend using multicrop2. There is no .Net versio...

Your image fails to convert for me on IM 6.9.10.36, IM 6.9.10.64 and IM 7.0.8.64 (and other IM 6 versions) Q16 Mac OSX Sierra. I get convert -quiet 101872_127179.TIF 101872_127179.JPG convert: 101872_127179.TIF: Null count for "Tag 34022" (type 1, writecount -3, passcount 1). `_TIFFVSetFi...

If all the files are PNG, which distinguishes between RGB and Gray, you can read the colorspace and/or type from the headers, I think. So the raster data would not need to be read, only the headers. This would be quicker. Other tools such as EXIFTOOL, might be faster. Snibgo would know more about al...

Comment out line 260: echo "shape=$shape; gain=$gain;" and try again. It is that echo that is causing the issue.
