Question

Batch process RAW exposures, please help!

Hello, I'm new to photoshop scripting for windows, and I was wondering if anyone knew how to batch process a folder of raw files, change the the raw's exposure, and save as jpg to another folder, based on a condition within the file's name, then close the opended jpg document.

My goal is to have a script that extracts the correct exposures from sets of three bracketed raw files, which I usually have seperated by 2 EV's. So for example, say I have a folder Called Batch Processing on the C drive, and I have two folders,

C:\Batch Processing\JPG

C:\Batch Processing\RAW

and in the RAW folder I have some files called,

Image_01_E01.cr2

Image_01_E02.cr2

Image_01_E03.cr2

If the file has "_E01" at the end, I want to open that raw file, change the exposure to -4, save the file with the same name, except the last 4 characters, and add some number to the end, so for example, it would end up being "Image_01" + "_E01". This would end up being saved to the JPG folder. Then open up the same file, change the exposure to -2 and save as "Image_01" + "_E02".

To make this post short, here is the conversion table I'm trying to achieve -

Image_01_E01.cr2 -> Image_01_E01.jpg Exposure = -4

Image_01_E01.cr2 -> Image_01_E02.jpg Exposure = -2

Image_01_E02.cr2 -> Image_01_E03.jpg Exposure = -2

Image_01_E02.cr2 -> Image_01_E04.jpg Exposure = 0

Image_01_E02.cr2 -> Image_01_E05.jpg Exposure = 2

Image_01_E03.cr2 -> Image_01_E06.jpg Exposure = 2

Image_01_E03.cr2 -> Image_01_E07.jpg Exposure = 4

After that, close all open files. Then, if there is another set of raws, repeat for them as well. For example -

Image_02_E01.cr2 -> Image_02_E01.jpg Exposure = -4

Image_02_E01.cr2 -> Image_02_E02.jpg Exposure = -2

Image_02_E02.cr2 -> Image_02_E03.jpg Exposure = -2

Image_02_E02.cr2 -> Image_02_E04.jpg Exposure = 0

Image_02_E02.cr2 -> Image_02_E05.jpg Exposure = 2

Image_02_E03.cr2 -> Image_02_E06.jpg Exposure = 2

Image_02_E03.cr2 -> Image_02_E07.jpg Exposure = 4

So basically this script would take 3 raws seperated by 2 EV's and extract 7 exposures, seperated by 2 EV's. I've done this manually, and merged them to hdr, and the results are actually pretty decent.

I tried doing this with actions and batch processing, but I had to have everything seperated in individual folders like E01, E02, etc. and I had to make an action for each step in the process.

I know this is probably a lot to ask, but I think it can be done, and I would of course credit the person in the script for helping.

Thanks in advance!

I think I was able to make a function to get the exposure time from the raw's xmp file. So the xmp file has to already be saved with the exposure time in the exif section.

function getEV(thumb){
    var Name = decodeURI(thumb.name).replace(/\.[^\.]+$/, '');
    var file = new File(thumb.path + "/" + Name + ".xmp");
    try{
        if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
        if(file.exists){
            file.open('r');
            file.encoding = "UTF8";
            file.lineFeed = "unix";
            file.open("r", "TEXT", "????");
            var xmpStr = file.read();
            file.close();
        }else{
            var xmpStr='';
        }
        var xmp = new XMPMeta( xmpStr );
        var exposureTime = xmp.getProperty(XMPConst.NS_EXIF, 'ExposureTime');
        if(exposureTime == undefined) exposureTime = 1;
    }catch(e){alert(e+"-"+e.line);}
    return exposureTime;
};

I was able to use the ui you put together from your hdr script, and used the functions from your cr2 script, to make the raw converter script. I've added a drop down list for the different conversion, and I added an option to either enter the exposure time for the middle exposure, or use the xmp's exposure time instead. So far I've only added a straight conversion method, where the files are converted, without any modifications, the 3 raw, and 5 raw conversion methods. Here's the script -

app.bringToFront();
main();
function main(){
    Prefs = {};
    try{
        var desc1 = app.getCustomOptions('0bafbed0-0bc7-11e1-be50-0800200c9a66');
        Prefs = eval(desc1.getString(0));
    }catch(e){
        Prefs.folder1 = Folder("~/desktop");
        Prefs.folder2 = Folder("~/desktop");

The script seems to work decent, so I plan on adding the other conversions I mentioned earlier, to it. If there is a way of getting the exposure time directly from the raw file, please let me know.

Hey Paul, I think I finally have a way of returning the corresponding exposure speeds from a middle exposure time. Which is by using a function to multiply fractions. -

function ExifEV(Input,Multiplier) {
    var EVval = Math.abs(eval(Input)*eval(Multiplier)); // Positive Decimal
    var EVvalN = 1; // Numerator
    var EVvalD = 1; // Denominator
    if (EVval < 0.5) EVvalD = Math.floor(1/EVval); else // For values less than 1/2
    // For values greater than 1/2 or values less than 1-1/2, returns 1000ths
    if (EVval < 1 || EVval > 1) {
        EVvalN = Math.floor(EVval*1000);
        EVvalD = 1000;
    } else
    if (EVval > 1.5) EVvalN = Math.floor(EVval); // For values greater than 1-1/2
    return String(EVvalN + "/" + EVvalD); // Return fraction
}

I've tested it using Extendscript and it seems to work fine. Using the function with an input value of 1/2000 -

ExifEV("1/2000","1/64"); // result = 1/128000 = 1/64x = -6EV

ExifEV("1/2000","1/16"); // result = 1/32000 = 1/16x = -4EV

ExifEV("1/2000","1/4"); // result = 1/8000 = 1/4x = -2EV

ExifEV("1/2000","1"); // result = 1/2000 = 1x = 0EV

ExifEV("1/2000","4"); // result = 1/500 = 4x = 2EV

ExifEV("1/2000","16"); // result = 1/125 = 16x = 4EV

ExifEV("1/2000","64"); // result = 1/31 = 64x = 6EV

Using an edittext to enter the value of the middle exposure to plug into the the function is the best solution I have so far. The problem with this is that the different exposure sets would probably have a different middle exposure speed, so you would want to run the script for sets that have the same middle speed, to ensure that that resulting speeds where correct. For example, say you have 4 sets of 3 exposures. 2 sets have a center exposure time (the exposure time of the E02 files) of 1/2000th, one set has a middle time of 1/500, the other set has a time of 1/1000 -

Set1_E01 - 1/500 Set2_E01 - 1/500 Set3_E01 - 1/125 Set4_E01 - 1/250

Set1_E02 - 1/2000 Set2_E02 - 1/2000 Set3_E02 - 1/500 Set4_E02 - 1/1000

Set1_E03 - 1/8000 Set2_E03 - 1/8000 Set3_E03 - 1/2000 Set4_E03 - 1/4000

You would want to run the script for the first 2 sets with 1/2000, again for the third with 1/500, and again for the last set with 1/1000. The ideal solution would be to read the exposure time from the e02 files to calculate the values for the other files., this way you wouldn't need to enter anything.

Is it possible to make a function to read the exposure time from a file?

Man, thanks again, for your help. I have so many ideas for these scripts, but hardly any programming experience to fully write them. Another idea I had was to make a script called "RAW to JPG Converter" with a drop down menu for various conversions for the EV spacing. For example, I named your script "RAW 3x2EV To JPG 7x2EV", which means 3 raws, separated by 2 EV to 7 jpegs, separated by 2 EV. I've modified your script to make a version that's called "RAW 5x2EV To JPG 9x2EV", which is 5 raws, separated by 2 EV to 9 jpegs, separated by 2 EV. It actually works just as good as the original, and since its from 5 raws, it has a very wide dynamic range. I just have to add the exif. The conversions from the bracketing chart I posted earlier which I plan on modifying are -

Straight Conversion

1 RAW to 9 Exposures x 1 EV (9 EV Range)

1 RAW to 7 Exposures x 1 EV (7 EV Range)

1 RAW to 5 Exposures x 2 EV (9 EV Range)

1 RAW to 5 Exposures x 1 EV (5 EV Range)

1 RAW to 3 Exposures x 4 EV (9 EV Range)

1 RAW to 3 Exposures x 3 EV (7 EV Range)

1 RAW to 3 Exposures x 2 EV (5 EV Range)

1 RAW to 3 Exposures x 1 EV (3 EV Range)

3 RAWs x 1 EV to 11 Exposures x 1 EV (11 EV Range)

3 RAWs x 1 EV to 6 Exposures x 2 EV (11 EV Range)

3 RAWs x 1 EV to 3 Exposures x 5 EV (11 EV Range)

3 RAWs x 2 EV to 13 Exposures x 1 EV (13 EV Range)

3 RAWs x 2 EV to 7 Exposures x 2 EV (13 EV Range)

3 RAWs x 2 EV to 5 Exposures x 3 EV (13 EV Range)

3 RAWs x 2 EV to 4 Exposures x 4 EV (13 EV Range)

3 RAWs x 2 EV to 3 Exposures x 6 EV (13 EV Range)

3 RAWs x 3 EV to 15 Exposures x 1 EV (15 EV Range)

3 RAWs x 3 EV to 8 Exposures x 2 EV (15 EV Range)

3 RAWs x 3 EV to 3 Exposures x 7 EV (15 EV Range)

3 RAWs x 4 EV to 17 Exposures x 1 EV (17 EV Range)

3 RAWs x 4 EV to 9 Exposures x 2 EV (17 EV Range)

3 RAWs x 4 EV to 5 Exposures x 4 EV (17 EV Range)

3 RAWs x 4 EV to 3 Exposures x 8 EV (17 EV Range)

5 RAWs x 1 EV to 13 Exposures x 1 EV (13 EV Range)

5 RAWs x 1 EV to 7 Exposures x 2 EV (13 EV Range)

5 RAWs x 1 EV to 5 Exposures x 3 EV (13 EV Range)

5 RAWs x 1 EV to 3 Exposures x 6 EV (13 EV Range)

5 RAWs x 2 EV to 17 Exposures x 1 EV (17 EV Range)

5 RAWs x 2 EV to 9 Exposures x 2 EV (17 EV Range)

5 RAWs x 2 EV to 5 Exposures x 4 EV (17 EV Range)

5 RAWs x 2 EV to 3 Exposures x 8 EV (17 EV Range)

5 RAWs x 3 EV to 21 Exposures x 1 EV (21 EV Range)

5 RAWs x 3 EV to 11 Exposures x 2 EV (21 EV Range)

5 RAWs x 3 EV to 6 Exposures x 4 EV (21 EV Range)

5 RAWs x 3 EV to 5 Exposures x 5 EV (21 EV Range)

5 RAWs x 3 EV to 3 Exposures x 10 EV (21 EV Range)

5 RAWs x 4 EV to 25 Exposures x 1 EV (25 EV Range)

5 RAWs x 4 EV to 13 Exposures x 2 EV (25 EV Range)

5 RAWs x 4 EV to 9 Exposures x 3 EV (25 EV Range)

5 RAWs x 4 EV to 7 Exposures x 4 EV (25 EV Range)

5 RAWs x 4 EV to 5 Exposures x 6 EV (25 EV Range)

5 RAWs x 4 EV to 3 Exposures x 12 EV (25 EV Range)

Although, if you add this option, and exif you would have to correlate with that conversion. For example, each shutter speed is seperated by 0.5 EV, so every other speed is seperated by 1 EV, and is 2x slower than the last, i.e. 1/500,1/350,1/250 - 1/250 is 2x slower than 1/500. With 1/1000,1/750,1/500,1/350,1/250 - 1/250 is 4x slower than 1/1000 and is seperated by 2 EV.

Awesome, I believe everything works great now. Commenting that section worked great for the hdr warnings, thanks a lot man.

The exif works, but I've noticed that you put explicit values for the exposure times. Is there a way of reading the cr2's exposure time as a decimal value from the middle exposure, and multiplying the next exposures by 4, 16, 64 and dividing the lower exposures by the same values? I think this would help a ton, as the exposure speeds would be different depending on the exposure speeds that were bracketed when you took the photos. The only alternate to this, that I can think of is if you set up a ui where you select from a drop down menu, the shutter speed of the middle exposure, and the other speeds are derived from that.

For example, here are the default shutter speeds you can choose from my camera -

1/4000,1/3000,1/2000,1/1500,1/1000,1/750,1/500,1/350,1/250,1/180,1/125,1/90,1/60,1/45,1/30,1/20,1/15,1/10,1/8,1/6,1/4,0.3,0.5,0.7,1,1.5,2,3,4,6,8,10,15,20,30

Say if we choose a middle speed of 1/60, the resulting 7 exposures would be 1/4000,1/1000,1/250,1/60,1/15,1/4,0. But if we choose the low end of 1/4000, the exposures should end up being 1/256000,1/64000,1/16000,1/4000,1/1000,1/250,1/60. I'm guessing that the default shutter speeds were rounded off, to keep a simplified pattern of division, so you could probably change 1/256000,1/64000,1/16000 to 1/250000,1/60000,1/15000 to keep with this pattern. If you add a ui I would also add in the same input and output directory options from the hdr script as well.

Well, it looks like your cr2 script works great. The last thing that would make it perfect is somehow saving the exif info, like with the Bridge script. The exif is important because merge to hdr uses the exposure time to compute the tone curve. You could use other software like Photomatix, where you you wouldn't need any exif, but then that would defeat the purpose of doing everything in Photoshop. I would just use bridge to batch edit the exif, but I can't get Bridge to edit any of the info in the camera section of the exif.

Also, I'm still getting the raw warnings with the hdr script. I've checked my preferences in Photoshop, but couldn't find any setting for that. I've also tried putting that displayDialogs line in the script, and it still gives a warning for each hdr set. Is there a specific place to put the line in? I've tried at the start, end, and in the HDRMergeGroups function. Anyway, thanks again for your continued help and patience.

Hi Ian, I have found where the warning is coming from, it is the CreateImageStack.jsx script in the

C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Presets\Scripts\Stack Scripts Only

folder.

If you comment out this section there will be no alerts.

 /*
 if (this.mustBeUnmodifiedRaw && hasCamRawChanges(doc))
 {
  this.giveWarning( "rawmod", "$$$/AdobePlugin/Shared/Exposuremerge/CamRawChange=: Files converted from Camera Raw format may lose dynamic range.  For best results, merge the original Camera Raw files.", false );
  this.exposureMetadataValid = false;
 }

Hmm, I was wondering how your script is converting the exposures from the cr2 files? It looks like the exposures are just taken from the cr2 files and darkened or lightened for the lower and higher exposures. They don't seem to contain any new information, or dynamic range from the Camera Raw dialogue settings. Here's a rar file with a comparison of converting with your script, and with converting them manually -

http://www.adrive.com/public/621616e2dbd233a75fb35400acba92f90a4965d6af8d9bc0e3f0a591483139e0.html

Also your hdr script works great, and it has a great ui with it. How long did it take you to write that up? It took me a couple of days for my script. The only thing with the script that I think needs to be changed is that you have to click ok on a dialogue stating that jpeg converted from raw loses dynamic range, and for doing hdr timelapse, it would be hard to have to keep clicking on that for each set. For some reason my script only asks for a confirmation once at the beginning.

As far as how my script works, it searches for if there are files in the exposure directories, then gets arrays from each folder containing files, then gets the first file element from each array, merges them together, takes the name from the first folder - the _E01, and repeat for the next element. I've fixed some inconsistencies in the script, and added dialogues for the user to choose input and output folders. You still need to have the exposure folders in the input folder. But I think its good to have them, to be organized, and its nice to be able to see the different files with the same exposure. I've also added the function to save as hdr in the output directory. Also I've added dos batch files to move files to and from the exposure folders. Here's a rar with the batch files and script -

Thanks for the info ian, I was using Image - Ajustments - Exposure to make all the alterations, seems that this is not the way forward, I thought it might save a lot of time rather than going through ACR for each exposure. I will have another go at that.

Its strange that you are getting prompts when running the HDR script and it goes through without a single prompt on my machine.

Could you try adding this one line and see if it fixs it..

app.displayDialogs = DialogModes.NO;

The script took less than an hour to write and test.

I will re-write the other script and get back to you.

Hey, Paul thanks again for your help. I will have to try this. Although it would be really nice to have this in Photoshop I really would need to have existing settings in the xmp files, not for the exposure, but for white balance and lens corrections, since I mainly use hdr for panoramas. Does this script delete the xmp files, or does it erase existing settings? Looking through your code, its hard to tell if it does either. If its possible to keep the xmp file, but overwrite the exposure setting, that would be great. Also does this save the correct exposure time in exif?

Also, I decided to have a go at an attempt at batch hdr merging. All of the testing of it so far seems to be positive. It merges exposures located in specific directories name E01, E02, E03. It merges multiple bracket sets of up to 19 exposures in each set. You don't really need much more than 15 depending on your EV spacing, to get an accurate hdr. The only thing that is stopping it from being perfect, is that I can't get the merged files to save in .hdr format, I can only get it to save as 32 bit psd, since, I guess that's the default file type. I tried looking in the javascript reference, and I can't seem to find the correct saveOptions to save as radiance hdr. Maybe I'm saveing them wrong. Although I could probably just as easily convert them with an action. Anyways let me know what you think, I figure these two scripts would go perfect together in Photoshop.

Hi, yes using xmp will be fine so long as it doesn't have the exposure set, if it has that will be taken as Zero.

Couldn't make much sence out of the script you have posted and you can't save HDR like you have it there.

You might like to try this that I've just put together, it will save 16bit as PSD and 32bit as HDR, you can select the group(s) of files to be processed.

It doesn't matter how many files per group, it will sort that out.

Hi Paul, I'm using the same setting that's in your picture, Always High Quality. I'm using Bridge CS5 4.0.5.11 if that helps.I also have Extendscript Toolkit CS5 as well as CS4 since I had to install the Premiere and After Effects CS4 32 bit support package if that helps also.

Hey thanks for all of your help Paul. The Shutter speed info seems to be perfect. I'm not sure why though, the correct exposures aren't being saved. Have you tried those files I posted, to see for your self?

Thanks for trying Paul, unfortunately the results are the same. This script gets saved as a jsx file right? Does it have to be saved from extendscript? I used a seperate text editor called PSPad which supports multi syntax highlighting including javascript.

~~Here's a link to a zip file with 3 cr2s, sorry its filedropper, I can't find any way to upload a file to this forum at all -~~

~~http://www.filedropper.com/ceilinglight~~

~~You can test the script for your self with these cr2s. Here's a zip file of the exposures converted manually -~~

~~http://www.filedropper.com/ceilinglightexposures~~

~~I also have a link for a zip file with 5 cr2s if you want to make a script with 5 raws -~~

~~http://www.filedropper.com/woodsfisheye~~

~~Also here is an excel table I made that has multiple conversions from 1, 3, and 5 cr2 brackets -~~

~~http://www.filedropper.com/rawbracketingcharts~~

The chart shows the EV range of bracketed cr2s and the conversions you can get from them. It assumes you can get +-4 EVs from each cr2. Although there is information you can get from 1 cr2 from -4 EV to +4 EV, its not recommended that you use exposures from the whole range from a middle exposure, because the results can cause high noise and contrast. The only times when you use an exposure from -4 is if the cr2 file was already underexposed or you use +4 from a cr2 that was overexposed. That's why I choose to use -4 and -2 from the E01 cr2 and +2 and +4 from the E03 file, and why I inly used the range of -2 to +2 from the E02 cr2.

I've also noticed that the script saves the jpegs without any exif camera data. Opening the cr2s manually in camera raw with photoshop, the exif seems to stay with the file. I'm normally not picky about the metadata, but I believe you need the correct shutter speeds embeded in order to here Merge to HDR work properly.

Although, even if you could keep the camera info, you would still need to change the shutter speeds to the correct ones, because the shutter speed would be the same as the cr2 file's speed. I think it would make this script perfect if you could adjust the shutter speeds to the correct ones.

~~For example, with the Ceiling_Light images I shot, converting the Ceiling_Light files manually without correcting the exif, the shutter speeds would end up being -~~

~~Ceiling_Light_E01.cr2 Shutter Speed -> Ceiling_Light_E01.jpg Shutter Speed = 1/2000 sec.~~

~~Ceiling_Light_E01.cr2 Shutter Speed -> Ceiling_Light_E02.jpg Shutter Speed = 1/2000 sec.~~

~~Ceiling_Light_E02.cr2 Shutter Speed -> Ceiling_Light_E03.jpg Shutter Speed = 1/500 sec.~~

~~Ceiling_Light_E02.cr2 Shutter Speed -> Ceiling_Light_E04.jpg Shutter Speed = 1/500 sec.~~

~~Ceiling_Light_E02.cr2 Shutter Speed -> Ceiling_Light_E05.jpg Shutter Speed = 1/500 sec.~~

~~Ceiling_Light_E03.cr2 Shutter Speed -> Ceiling_Light_E06.jpg Shutter Speed = 1/125 sec.~~

~~Ceiling_Light_E03.cr2 Shutter Speed -> Ceiling_Light_E07.jpg Shutter Speed = 1/125 sec.~~

~~Since the converted exposures should be seperated by 2 EV each, the resulting speed should be 4x the last, so I would reference the Ceiling_Light_E02.cr2's speed which would be 1/500 sec. -~~

~~Ceiling_Light_E01.cr2 Shutter Speed -> Ceiling_Light_E01.jpg Shutter Speed = 1/32000 sec. = 1/64x~~

~~Ceiling_Light_E01.cr2 Shutter Speed -> Ceiling_Light_E02.jpg Shutter Speed = 1/8000 sec. = 1/16x~~

~~Ceiling_Light_E02.cr2 Shutter Speed -> Ceiling_Light_E03.jpg Shutter Speed = 1/2000 sec. = 1/4x~~

~~Ceiling_Light_E02.cr2 Shutter Speed -> Ceiling_Light_E04.jpg Shutter Speed = 1/500 sec.~~

~~Ceiling_Light_E02.cr2 Shutter Speed -> Ceiling_Light_E05.jpg Shutter Speed = 1/125 sec. = 4x~~

~~Ceiling_Light_E03.cr2 Shutter Speed -> Ceiling_Light_E06.jpg Shutter Speed = 1/30 sec. = 16x~~

~~Ceiling_Light_E03.cr2 Shutter Speed -> Ceiling_Light_E07.jpg Shutter Speed = 1/8 sec. = 64x~~

~~However, I'm not even sure sure if this is possible, because for, me I can't manually edit the camera exif section in bridge, and I have to use a seperate metadata editor.~~
