If I have a set (30) of portrait photos of a person (head and shoulders), what is the best way to resize & crop them such that the subject will be the same size and in the same position on each photo? Is there a way to create a 'wire-frame' or similar to use as a template for each? Some other technique so it's not trial and error?
In Editor, go to File>process multiple files.You can batch resize. However, this process does not provide the ability to crop. Moreover, the position of each subject will remain as is, e.g. if one subject is off center, there is no provision to move automatically towards the center.
Suggest that you try it out with a few dummy files. Make the destination folder different from the source folder. Also, aggregate portrait and landscape oriented files into different batches for processing.
