Hi,

Thank you for your interest in BatchPhoto.

With BatchPhoto you can use the Auto Crop filter to crop your photos to a predefined aspect ration (ex. 16:9, 4:3, etc) in batch mode. You can try it for free by installing from here:

Let me know if there is something else.

I am taking several hundred product photos on a white backdrop. Is there a way/program that can center a batch of photos?
