Photoshop script - 2 sequence images auto align

Edit: Oops, wrong topic!

Dear all,

thank you for all the posts. This forum is awesome.

Please allow me to be more precise about the project and the script.

We have 2 old negative film rolls shot with a camera using a primitive system of Technicolor. As I said, one roll captured the "red" colors while the other captured the "green" colors. Both film rolls are on black and white stock (one panchromatic, the other orthochromatic).

We are planning to scan the film rolls at 4K or 6K resolution using a motion picture scanner. After that, it's when things get interesting...and complicated.

As I said, the idea of the script is to load scan "green" 01.dpx and load scan "red" dpx into a file (in different layers). Perform the auto-align, then I was thinking to load an action because I need to composite the files to obtain the color. After, I would flatten the image and obtain the final "colored" file as .dpx.

This is the idea. It's a very interesting project but quite complex, specially with my limited knowledge of scripting. But, I'm learning a lot in this forum.

Thanks!

The next test you need to make is to see if Photoshop Autoalign layers will work on the two images stacked. If the can it should be quite easy to script the process.

Here I took and image layer duped it increased the canvas size lowered the opacity of the top layer and miss aligned the two layer.  I used an action to target the visible layers  and used Auto align layers to align the back. I use and action for auto align layers has a dialog that is not displayed when the action is played.  You will also need to use scriptlistener code for autoalign layers in you script for there is no DOM interface for it.

I wrote a script for someone recently that processes pairs of files the files were in a single folder and the names sorted the file so the front and back images were next to each other.   You could write a script like it the used one or two input folders and a single output folder.  You would also save out PSD file not jpeg files.  You would most likely open the first  convert to a normal layer, expand the canvas some place in the second, rasterize the placed layer, target both layer and auto align layers.

The script I wrote to help someone process pairs  of images.

var defaultFolder = "~"; // Default to desktop
var inputFolder = Folder.selectDialog("Choose a folder of images to process.", defaultFolder);

var fileList = inputFolder.getFiles(/\.(nef|cr2|crw|dcs|raf|arw|orf|dng|jpg|jpe|jpeg|tif|tiff|psd|eps|png|bmp)$/i);
if (fileList.length%2===0) { // even number of files
  for (var i = 0; i < fileList.length; i++) { // Loop through files
     app.open(fileList); // Open First of Pair

Can the image be aligned manually now?  They were shot with different cameras  from different locations.  Was there any special setup used to sync the taking of the images  at the same distance and same focal length.  Was the subject moving.   It is highly unlikely that image taken with different cameras can be aligned if the were not taken with that in mind using some specialized  setup. Perhaps have some reference and alignment points in the captured images.

Do the negatives you scanned align?
