Portraits Cropping Automation

Jazz-z posted a script not too long ago where he basically used  a liquify mesh he had  that he use with liquify  to select  the head in a portrait image.    You should be able to modify that script to be able to set a 4:5 aspect ration portrait selection. To crop your portrait images to approximately the same size 8" x 10"  Portrait where all heads will be about the same size and located in the same image area.  I would use the modified script in an action that would resize the 4:5 crop image to be 8" x 10" at the ppi you want.  The action could also be made interactive where  you could reposition the position of the Crop selection the modified script sets so you can tweak  portrait  selected before the action crop the image and resizes to 8" x 10".   

Something like:

You show all your original portraits are near the sane size and all seem to be shot by the sane camera and setup.  You would need to modify the script to sett and appropriate 4:5 selection for your original image.    I downloaded some random portrait from the web.  They all were croped 8"x10" however the portrait composition varies  because the camera set up and  portrait compositions varied greatly as did the image sizes.

I did find the script. It's customized for our standards, but you can get an idea. What it does is create a set of shape layers in which you size and position over a face. Then if you select "Add permanent guides, it creates cropping guides. If you leave that uncheck, it crops, but it will do it to our specs DPI, etc.

Hi Stephen.

As with most things in photography – if you wish to save work in post-production, you have to get it right at capture.

Yes, I do agree with you. But I have not captured those images. I generally do the post-production only. And I have to be faster than the others :-) and I believe in automation. I know there will be manual work required but It saves a few percents of manual work. Maybe 50% or more than that. :-)

If you know any other plugins for automated cropping. Please suggest.

As Bojan and Stephen said before it's difficult proces. But you can try this:

use File > Scripts > Load Files into stack option and load as many pictures you want

Crop your document

Exort > Layers to files option allows you to save independent files

But it works if your photos are almost the same
