Trouble changing Camera RAW settings in Javascript (worked in CS5, but not CS6)

i upgraded master collection cs6 production premium cs5, , camerarawopenoptions settings in scripts had working in photoshop cs5 (64-bit) using extendscript cs5 no longer working photoshop cs6.  no error messages, settings specify in scripts (for example, camerarawopenoptions.exposure=2.00) not take effect when image opened.  other photoshop properties , actions within script working correctly.

 

note issue in photoshop cs6.  can use extendscript cs5 or cs6, , result same.

 

here way changing settings in script:

 

var rawoptions = new camerarawopenoptions;

//rawoptions.settings=camerarawsettingstype.custom;

//rawoptions.settings=camerarawsettingstype.selectedimage;

rawoptions.settings=camerarawsettingstype.camera;

rawoptions.exposure=+2.00;

rawoptions.vignettingamount = 0;

rawoptions.vignettingmidpoint = 0;

rawoptions.contrast = 50;

rawoptions.saturation = 0;

rawoptions.shadows = 0;

rawoptions.luminancesmoothing = 0;

 

var jpgopts = new jpegsaveoptions;

jpgopts.quality = jpegquality;

 

//perform loop through files

app.open(testlisting[0], rawoptions, false);

app.activedocument.close(saveoptions.donotsavechanges);

for (var nfile = nstart; nfile < nstop; nfile++)

  {

    app.open(testlisting[nfile], rawoptions, false);

    fnamesave = new file(savepath+"/"+testlisting[nfile].name);

    app.activedocument.saveas(fnamesave, jpgopts, false, extension.uppercase);

    app.activedocument.close(saveoptions.donotsavechanges);

}

i found few of them work.

 

camerarawopenoptions.tint=0; // works (-150 150)

camerarawopenoptions.temperature=5500; // works (2000 50000)

camerarawopenoptions.luminancesmoothing = 0; // works 0 100

camerarawopenoptions.saturation=50; // works =100 100

camerarawopenoptions.vignettingamount=0; //works -100 100

camerarawopenoptions.vignettingmidpoint=0; //works -100 100

 

 

these ones not work:

 

camerarawopenoptions.brightness=0; // not work (0 150)

camerarawopenoptions.contrast=0; // not work (-50 100)

camerarawopenoptions.exposure = 0; // not work (-4.0 +4.0)

camerarawopenoptions.shadows=0; // (0 100) not work

camerarawopenoptions.whitebalance=whitebalancetype.shade; // not work

 

i noticed that, doing file-->file info--> "advanced" tab-->expand "camera raw properties" ones not work have either been removed (brightness) or had "2012" added names in xmp in conversion cs5 cs6.

 

it appears mapping javascript objects/properties how photoshop knows them broken new version.  there way fix this?

 

is there alternate way going through xmp?

 

unfortunately, i'm wanting use "exposure", 1 of ones broken.  main script sets custom exposure each image (trying smooth out ev jumps between successive images in sunset time lapse).
