I thought maybe it's time I shared some of the things in Photoshop that I'm at least competent with since everyone is sharing retouching techniques. I'm hoping this can be helpful to people in their workflow to perhaps cut down on some time spent by letting the automation within Photoshop do some of the work quicker.

Anyone is welcome to post your own.

If you're not familiar with adding/running scripts, here is a link to the help file at Adobe.com on the subject.

You can use any text editor to make these scripts or copy-paste into a text editor such as Notepad in Windows. Creative Suite editions of Photoshop were packaged with the Extendscript Toolkit which makes writing/debugging/using scripts easier.

Save to your Photoshop/Presets/Scripts folder with a .js extension. You can also use a .jsx extension. Example: myscript.js

Close Photoshop and restart so the script will appear in your File > Scripts menu. You can then point a hotkey combination to it or create an Action to run the script.

To create the Action to run the script, go to your actions palette and record a new action. Set it up as you want with the F key combination if you so desire. Once that initial record dialog is to your liking, click Record and immediately click the stop button in the actions palette. Now, go into the Actions Palette menu (upper right hand corner) and choose "Insert menu item..." You will see a dialog appear. Ignore this. Go under File > Scripts and find the script you wish to run. Click on that script in the menu. Now click on OK in that dialog you ignored earlier. Now your action should run that script.

If you have any more questions about basic writing/using scripts just ask here in the thread and I'll answer and update the second post with Q&A's

The first script that is useful to me is using a 50% gray Softlight layer to dodge/burn out shadow areas. This can also be used to darken lighter areas to match a darker area.

Edit: I forgot to mention when I originally posted this. This script will work in RGB, CMYK, or LAB modes.

This script will also take into account color casts in shadow vs light areas whereas simply using white and/or black won't always do this for you. This will set up your foreground color and background color to values that are close (in my experiments) to adjust a shadow area to look like a lighter area and vice versa if used at 100% opacity and 100% flow. It may not be perfect and may require you to make your own adjustments to the script for your own taste.

To use this, set your background color to the area you want to adjust and your foreground color to the area you want as a reference. Set up your Softlight layer with 50% gray fill. Run this script. Select the foreground color and using your brush, paint on the Softlight layer the area you want to adjust to match the reference area.

You may have to take a few samples or even use more than one Softlight layer if the adjustment is a large one.

Here is the script:

//This script will allow for dodging/burning a darker/lighter area to match a lighter/darker area by using
//a 50% gray layer in SoftLight blend mode. To use this, select the area you want to adjust as your
//background color, select the reference area as your foreground color, then run this script. Create a
//50% gray SoftLight layer above the current layer. Select the foreground color and paint the area you
//want to adjust.. The default settings will make the background color slightly lighter than the foreground
//color for a lighter (brighter) adjustment.

var shadowColor=new SolidColor;
var lightColor=new SolidColor;
var fgColor=new SolidColor;
var bgColor=new SolidColor;

shadowColor=app.backgroundColor;

cmykMult=1.2; // A multiplier in CMYK mode that I found works well. You can change this to your taste.

switch (app.activeDocument.mode) {

var bBase=134; // The base number plus a little extra. Adjust to taste.

case DocumentMode.CMYK:
var fBase=50; // The base number I found works best as a midpoint/starting point in CMYK mode. Adjust to taste.
var bBase=45; // The base number plus a little extra. Adjust to taste.
var corMult=cmykMult;

fgColor.cmyk.cyan=Math.min((corMult*(lightColor.cmyk.cyan-shadowColor.cmyk.cyan)+fBase),75);
fgColor.cmyk.magenta=Math.min((corMult*(lightColor.cmyk.magenta-shadowColor.cmyk.magenta)+fBase),68);
fgColor.cmyk.yellow=Math.min((corMult*(lightColor.cmyk.yellow-shadowColor.cmyk.yellow)+fBase),67);

bgColor.cmyk.black=Math.min((corMult*(lightColor.cmyk.black-shadowColor.cmyk.black)+bBase),90);

break;

}

app.backgroundColor=bgColor;
app.foregroundColor=fgColor;

And here is a before and after to give you an idea of what it does. This was using the brush at 100% opacity and 100% flow.

BEFORE

https://www.nunuvyer.biz/Photoshop/Shadow-Before.jpg

AFTER

When using a white brush to dodge the shadows, I would get a slightly red color cast on the wall where the shadow was. This was most likely from a light reflection off of her pants. Using this script, the brush colors were set to adjust for that color cast.

The next script was discussed here by Sean Baker. It basically does everything he outlines for output sharpening. This script will determine whether you are working in 8bit or 16bit and adjust accordingly. The image must be in RGB mode, though. A big thanks to Sean for outlining this method.

The script is located here. You can just save it to your computer and copy it to your Photoshop/Presets/Scripts folder.

To use it:

1. When you are ready to output your image for the web or wherever else you need to output, just run this script.

2. You will be presented with a dialog. This is where you choose your output size. The dimension you enter here will be the dimension you want the long side of the final output image to be. Dimensions are in pixels.

3. The script will run the proper Gaussian Blur on the image as per Sean's instructions based on the resizing you ask for. It will then go through the steps to set up the output sharpening including resizing your image.

4. You will be presented with 1 Gaussian Blur dialog and 2 Smart Sharpen dialogs. These you will have to determine the settings that work best for you.

5. When finished, you will have your original layer and a "Sharpened" layer with a mask attached. You can paint black on the mask to tone down the sharpening effect wherever you like.

6. Enjoy! smile

Very nice I was wondering if a script can be created to match colors by number in an image. My concept is open image one measure the diffused skin highlight and skin shadow on skin control point one and control point 2 and do the same on image number two then run a script that would create adjustment layers on image number 2 matching the outputs to image one. I currently do this by hand any ideas would be appreciated.

Here's a simple, and potentially useless for most, script that is just a basic timesaver for me. I do a lot of keyart development so am constantly going back 'n forth between Photoshop & Illustrator/InDesign etc. And I hate placing huge layered files in those apps, so i always save as flattened TIFFS. Basically, i hated tweaking my layered doc, and then going to File > Save As... > blah blah.

This script saves a TIFF file of your working PSD into a predesignated folder directory. In my case, all my projects have a 'Layered Files' folder, and a 'Placed Art' folder. So no matter what project folder I'm in, this script will save a flat TIF to the Placed Art folder within it. Note, it does not ask you to overwrite the old, so it will by default, REPLACE THE EXISTING FILE, if there is one. I assign the script to a key command for quick use. If you use this, I sugggested trying it out on a dummy file just to get the hang of it. It won't do anything to your PSD file, just saves a copy of it as a flat TIFF. But it will replace the old if one is existing.

Anyway, just wanted to contribute to a great thread idea. Here it is:

//This script saves a flattened TIFF file of your working layered file into a predesignated folder
//To change the folder where it saves, look at the first line and replace "/../Placed\ Art/"
//with your preferred folder hierarchy. in my example, the script will back up one directory
//from the current working file directory, then save the TIFF to a folder called "Placed Art"
//be sure to keep the "" around the folder path.

var saveFile = new File(activeDocument.path + "/../Placed\ Art/" + activeDocument.name);
SaveTIFF(saveFile);

function SaveTIFF(saveFile){
tiffSaveOptions = new TiffSaveOptions();
tiffSaveOptions.embedColorProfile = true; //this will embed your currect color profile
tiffSaveOptions.alphaChannels = false; //change to true if you want to save alpha channels in your TIFF
tiffSaveOptions.layers = false; //this simply flattens the TIFF and saves without layers. Does not affect your PSD file
tiffSaveOptions.imageCompression = TIFFEncoding.NONE; //this sets it to zero compression
app.activeDocument.saveAs(saveFile, tiffSaveOptions, true, Extension.LOWERCASE);
}

If I'm understanding you, you don't need a script to do this. Once you have a curves or any adjustment layer set on one image, you can drag it and drop it onto another image to duplicate it for that image.

If you are thinking of doing this in a batch process, I think a script might work best.

Very nice and useful. With a little tweaking you can make this so it won't overwrite the existing file. I do something similar in my workflow when I output for web and save as a jpg. If a jpg file exists, it gets renamed to filename-1.jpg unless filename-1.jpg exists then it tries filename-2.jpg and so on until it gets to a number that doesn't exist. This way my most current is always just filename.jpg and I can see if it's better or worse than the others if I'm trying new techniques.

Awesome!

definitely. In my workflow, I just didn't want to have to re-link to a new file each time I go back to InDesign. But yes, writing a new file is always a 'safer' bet. smile

Here's the code as it is for .jpg files that steps through and renames the old file to filename-1.jpg before saving the new file to filename.jpg....

var im=app.activeDocument;
var f=new String(im.fullName);
var len=f.length-4;
var plen=new String(im.path).length +1;
var ps=File(f.substring(0,len)+".psd");
var jp=File(f.substring(0,len)+".jpg");
var i=1;
if (jp.created)
{
jpg = File(f.substring(0,len)+"-"+i+".jpg");
while(jpg.created)
{
++i;
jpg = File(f.substring(0,len)+"-"+i+".jpg");
}
jp.rename(f.substring(plen,len) +"-"+i+".jpg");
jp=File(f.substring(0,len)+".jpg");
}

Not exactly copying the adj layer did not give the same effect or color shift I just tried it to be sure. Maybe a better explanation of how the process I am doing works.

Step one on the reference image skin color I set a control point with the color sampler tool in the diffused highlights using that point in my example above I get the values R 235 G 230 B 226 measures C 5 M 8 Y 8 K0. Now I repeat the process on image 2 first locating a diffused highlight on the skin I set a point and setup a adjustment curve layer the values input of red 247 I set the output to match 235 and same with green and blue to match the values of the reference image this makes the two images diffused highlights almost the same color C 6 M 7 Y 8 K 0 from C1 M31 Y43 K0 . When I move the curve the highlights in another image change to the value of C 8 M 7 Y 22 K 0 from C 2 M 32 Y 58 K 0 close but not exactly a match. Just started getting into doing colors by the numbers and trying to find a quicker way to get it done.

OK! I got you now. You want to match chosen point to chosen point between images.

Let me do some research on this to find the easiest way. I'm sure I can come up with something. smile

OK. Just so I'm clear on this before I get too far into it.

What you are doing is selecting a point in a reference image. We'll use RGB mode if that's OK. Let's say the point comes out to your example of R 235 G 230 B 226. Then you go to your working image and select a point and using your example, this point is R 247 G 240 B 222. You are making a curves adjustment layer on your working image and you go to the red channel and set a point at IN: 247 OUT: 235 then on the green channel IN: 240 OUT: 230 then on the blue channel IN: 222 OUT: 226.

If this is correct, I have one question. Are you maintaining your 0,0 and 255,255 anchor points on each channel? So for the red channel you'd have anchor points at IN/OUT values of 0/0, 247/235, 255/255.

Or am I missing something?

Yep the only moves are the Red Green Blue values the rest of the curve stays the same.

OK. I got the meat of it done now. For an interface, how do you want to do this? I can have it 2 separate scripts....one to set the reference color and the other to apply that to the active document or a single script that pops up a dialog asking if you want to apply the color the the document. If you say no to this, it will take the color selector point as a new reference. This will give you a dialog each time you want to apply the color to an image so I'm not sure you'd want this.

I hope that makes sense. I think the 2 script method would be easiest. Then you know what's going to happen.

Try these and see if they work for you.

http://www.nunuvyer.biz/Photoshop/Scrip … eColor.jsx
http://www.nunuvyer.biz/Photoshop/Scripts/SetCurves.jsx

Use the first one to set your reference color by using your color sampler tool and hold down while picking your reference point. Then run the script.

Use the second one the same way with the sampler tool and then run the script.

To delete the points after you're done, hold + and click the spot with the sampler tool. I could also have the script automatically delete the points. Or you can add the line:

docRef.colorSamplers[0].remove();

to the end of each file.

I have a feeling it's going to need more work since I'm not exactly sure what you're going for. But the main part of it is done. The rest is just tweaking.

Totally awesome but I was wrong I do need to adjust the RGB value after testing on various image guess I missed that one the numbers came across slightly off without adjusting the rgb value of the curve this is sweet as hell. Man this will make matching color in a series of photos so much easier when I get heavy handed retouching or need to steal a tan lol.

Thanks alot!!!!

So this works for you?

I forgot to mention that if you have your color sampler tool set to an average instead of a single point, the numbers may not match. When you set a sample spot using the tool, the values shown in your Info panel are the average but the script can only get from the point actually sampled. I scratched my head for awhile trying to figure out why it didn't match.

With this, it would be a simple thing to add extra points to the curve if needed. It would require a looping structure. Something for another day. smile

Cool cool IC Thanks again awesome work. Now I understand whats going on if its only one point vs an average dang ps it should allow reading the info panel as is lol.

Every now and then I get this error popping up any idea?

Thanks again this is most excellent.

Cool cool IC Thanks again awesome work. Now I understand whats going on if its only one point vs an average dang ps it should allow reading the info panel as is lol.

Every now and then I get this error popping up any idea?

Thanks again this is most excellent.

What version of Photoshop are you running? It also could be something to do with the active layer. I'll have to check it out.

Normally this error comes up when the script tries to do something on a layer or document that isn't allowed. For this, that line is in the curves settings step where it sets the points on the curve. This could happen if for some reason the wrong layer is selected (not a curves layer) or it's trying to set a point that can't exist.

Is there a way for you to duplicate this? Or is it random?

I will try to pay more attention next time on whats selected on the image excellent work again.

This has me thinking of many uses for this save a skin database of shadow and highlights and be able to pull up a list that I can select and make a adjustment curve from them for quick color matching no need to even have a second image open. With your setCurves script with a little modification and a menu added for skin selection or entering the values manually makes it very doable I think.

Ive got a similar script being written for a function like this by a company in California, started it a few months ago with a guy named Don and its nearing being completed. I have different specifications...but the concept looks somewhat close.

That is entirely possible. This can be set up with a dialog to allow you to set up your own colors and save them into a database type thing (*.ini file) and retrieve them with a dropdown menu. Also, the RGB values can be set with slider controls or direct input into a text box or grab from a point on an open document.

This can also be done in any mode, really. CMYK, Lab, etc.

What I have here is simple, really. Although it can be expanded. I'm guessing yours is quite a bit more involved.

This thread has me juiced on scripting I already have created a dialog to control curve creation and building a list of skin swatch images from xml file to set the adjustment colors if I can figure out the best way to turn the colorsampler from a point to a pixel averaging tool this would be over the top cool. I believe I maybe able to retrieve the colorsampler position then just measure the colors around its position creating my own average based on different sampling sizes. A fun project.

If you want an average of your color picker sampler as set in your settings, use the method I used in the Shadows Dodge/Burn script. This might be a bit of a pain, but it will at least give you the average.

Here is a script to multiply decompose a given image into any number of spatial frequency bands, selectable by the user. Includes options to add clipped curves adjustment layers to each intermediate band, and works on both 8 and 16bit images. Go easy on me, I'm new to this script thing.

hello guys smile

))

this thread is a bit old already, but...
hmmm... this sounds very useful but still can't get completely what author is trying to achieve. for example pick a sample and then match a batch with the first image (to apply the same skin color to all images)? but it will work only for the same type (from the same photo session images), right? because in one image R44 can be different from other R44, it maybe more like R87, for example.

To which author do are you referring here? There are a few different scripts and ideas going on in here.

Huge thank you to the valued contributors of this thread... it's fun to geek out and read about experimentation. I may not understand all of these conversations but this proves I have a lot to learn. Just when you think you have mastered PS, someone shows you that you have only just begun.

Bows to valued contributors. hopefully I can find and follow you on FB
