Batch processing of photos (black and white, digitized from film)?

Question

Adobe Photoshop

Hello!
My parents kept a lot of films from an old camera. In order not to lose this good forever, I wanted to digitize them. I assembled a small stand, from a DSLR and fasteners, for pulling the film. In general, digitizing was not the most difficult task.
There are a lot of photos on hand. Processed in Photoshop the highest quality photos. But since there is no processing experience, it turned out that all the photos have a different color scheme, some are yellow, some are bluish.
I need advice on how to fit all the photos to one color. Is there a plugin for photoshop?

Answer 1

Specify the size of the "heap" of photos :)
If it's simple, then you can make an action and convert all the photos to grayscale, i.e. in greyscale.
