I'm not sure if this can be done either with a plug-in, external code
or with Photoshop straight out of the box, but I'm sure you folks can
tell me
if I'm on the right track, or just out of my mind....

I have a folder with multiple pdf documents in it. Each document is
a combination of text and images. I almost always have to use "Edit
Image" on each image and, using Photoshop, go to "Image > Adjustments


> Shadows/Highlights", then set "shadows" to 100%, click "ok" and


save. It's time consuming to due with every image.

Is there a way to create a batch process to run this for me on each
image within each document within the designated folder?


Thanks for any input you can provide.
