Primary Source Processing

Hello,

I'm working on a primary source research project with thousands of images of letters, photos, musical scores, and more (some are PDFs already, though many still need to be compiled into PDFs), and I got the Adobe Pro subscription in order to manage and process these. However, I'm finding that many of the tools that I need (such as batch-crop/fast-cropping tools and the ability to transition from a color document into a b+w document) aren't available, or the work is rather painstaking to do in Adobe. I'm curious if anyone else has run into a similar issue -- do you use Adobe to do this work? Do you have any tips/tricks?

Additionally, my free trial runs out tomorrow, and I'm wondering if anyone knows if Acrobat Studio would be more helpful for this. I've seen that Lightroom has the capacity to Batch Crop, but I'm not sure if that's the right option for me. Any ideas?

Thank you so much!
