Batch HDR creator for Photoshop JavaScript

psbatchhdr.js

// Batch Creation of HDR files
// -----------------------------------------------------------------------------------
// Opens a dialog box, asking for the container folder.
// The container folder must have separate sub folders for each of the HDR image series
// The output can be saved in a subfolder with an arbitrary name by
// changing the options below.
//
// example: to save hdr files as 
// C:\container\hdrseries1\myhdrfolder\myhdr.psd
// change the options HDROutputFolder to "myhdrfolder" 
// and option HDRFileName to "myhdr"
// 

// Extensions of source image files
var pictureExtensions = "*.jpg";
// Sub-folder to save the resulting HDR file. This folder will be created if it does not exist.
//var HDROutputFolder = "";  // disable subfolder like this
var HDROutputFolder = "HDR"
// Filename for saved HDR file. Do not set the extension here, extension is set automatically according to saveResultAsEXR option.
var HDRFileName = "HDR";
// Save EXR file (requires EXR plugin) If set to "false" saves the HDR as a  .PSD file
var saveResultAsEXR = false;
// Overwrite existing HDR output files? If set to "false" skips creating HDR files for already created image sets.
// This is useful for adding some new HDR sets into the container folder, and running the script again 
// to crate HDR files only for the newly added series.
var overwriteExistingHDR = false;
// --------------- End of settings ------------------- //
