Batch saving layers as individual jpegs

I have searched the forums and haven't quite found what I was looking for. I have assembled a wholel lot of scanned pages from my sketch pad into one psd file. That file has guides which I use to register and align every page (each page is therefore its own layer). Is there a way I can make an action and save off each individual layer as its own jpeg? I set up an action but I don't know how to get photoshop to save it with a distinct namespace. The first action I set up basically prompted me to re-name each layer as I saved it, which isn't really saving time. What I want is for the action to start at the bottom layer and turn off the visiblity of all the layers above it, save the visible layer as a jpeg with a name based on the layer and then turn on the next layer's visibitlity and repeat, until all layers have been saved. Is that doable?
Any help would be appreciated.
Thanks

I gave this a shot and it did create multiple files for each layer but there is a problem.
If I manually "Save for web" as jpeg at 80, my jpeg weighs about 8KB.
If I use the script to export the jpegs at "Quality" of 8, I end up with the same image at 55KB.
Thats a big difference, is there something I am not doing in order to get the same compression?
When you save for web at 80% are you saving at 100% size or are you also reducing the images pixel size?

Saving layers as individual files all at once

Since I am creating files to use in PrEl I need multiple layers to become multiple tracks. Is there any way to simply save all the layers of my files as individual files without unhiding each layer and then saving each file one by one.

Have you also asked on the PremEl forum? I do not believe that PSE has any means of doing this - except in this special context, I cannot imagine why anyone would want to. I was wondering if PremEl has an import facility to deal with it for you.

How can I switch from photos saved as MPEG4 in a slideshow to individual JPEG photos?

When I imported pictures from my camera, I inadvertantly saved them as a slideshow. In order to be able to burn these to a CD that will play on a DVD player or Windows computer, it seems the pictures need to be saved as individual JPEGs, not MPEG4. How can I change the format, or switch the view?

An mpg4 is a movie, you can't break that apart to individual frames, I'm afriad. However, I do not believe this is correct:
In order to be able to burn these to a CD that will play on a DVD player or Windows computer, it seems the pictures need to be saved as individual JPEGs
To play on a DVD player you need to use an application that can author such a disk. iDVD if you have it, or Toast. Search on MacUpdate

Photoshop CS6 program error saving layered files

I recently updated my adobe software and I am still getting issues with saving layered files. I keep gettting program error - only occasionally. Sometimes saving to my desktop works and other times it doesnt. Other coworkers are experiencing same thing ever since they updated. It happens when working on a layered file for any length of time and need to save it out as a layered photoshop file. We are forced to flatten and save as a tif and loose our layers. I think it has something to do with background task but not sure...

Drag the file to your desktop, open the file there, do your edits, save, and then drag back.
Let us know what you are working off. If server, what server software are you using. System preferences >> spotlight, uncheck all items.

Batch Saving jpg from Camera Raw PSE 6 for Mac

I'm running PSE 6 for Mac. I'm shooting in RAW to retain all data from sensor. My work flow is straight forward.
Review photos on CF card and do initial throw away of bad photos.
Download from CF card to Backup drive to preserve original photos.
I upload photos to Bridge, keyword, grade, and copywrite, etc. then open in Camera Raw and process as necessary; exposure, recovery, sharpen, fill-in, crop, fill-in etc.
Select all and do a save (default is .png) to save my changes. Since Camera Raw will not save to jpg format I open in PSE6
My workflow can change here depending on what my end product will be but usually I'll send some photos out to share which is the subject of another post. I can't make the program resize more than one photo for email even though I have all of the photos I want to email selected in the film strip.
Anyway my process for batch saving to jpg is as follows:
Select all of the photos (I will select only those that have been cropped to the same size such as 4x6) in the film strip.
Open File > Process Multiple Files
Fill out the dialogue box (see attachment) and press OK
The next thing that happens completely negates the automated process, I get the Save As Dialogue box for every photo (see attached)
I delete the "copy" text and save
   6. Some of the photos turn out black under preview in finder
   7. When I try to reopen the jpg in PSE6 I get an error message (see attachment)
Any help is appreciated.

Review photos on CF card
Stop right there! That's a very bad idea.   You should not be viewing images that are still on the card. Download them to your local hard drive first. Otherwise you run the risk of the software writing to the card and destroying the format.
This excerpt is from a long-gone post by author Bruce Fraser:
Bruce Fraser - 4:17pm Jun 14, 04 PST (#5 of 21)
Opening files directly from the camera is a bad idea for a variety of reasons*, and it most certainly isn't faster than using a FireWire or USB2 card reader.
         • Drains the camera battery
         • Runs the risk of the software you're using to open the images writing to the card and destroying the format
         • Runs a small but significant risk of USB power frying the camera
         • Slowest method known to mankind of getting images off a CF or SD card

Why can't I see the individual .jpegs in iphoto library?

First off, I would like to apologize to the group in advance if these question have been asked 1000 times!!! I didn't see an answer when I searched the forum!!
#1
Can someone tell me why I can't see all of the individual .jpegs in the Iphoto Library when I navigate to the directory in Finder??
#2
What is the best way to back up all of the pictures in the libray to use the .jpegs elsewhere, have them printed etc.??
Thank you

#1
Can someone tell me why I can't see all of the individual .jpegs in the Iphoto Library when I navigate to the directory in Finder??
Since iPhoto 7 (iLife 08) the old iPhoto Library Folder is now a Package File. This is simply a folder that looks like a file in the Finder. The change was made to the format of the iPhoto library because many users were inadvertently corrupting their library by browsing through it with other software or making changes in it themselves.
Accessing the files via the Finder has never been supported in iPhoto.
#2
What is the best way to back up all of the pictures in the libray to use the .jpegs elsewhere, have them printed etc.??
WHy would you want to "back up all of the pictures in the libray to use the .jpegs elsewhere" ? Why not use them via iPhoto?
There are many, many ways to access your files in iPhoto:
*For Users of 10.5 and later*
You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
Uploaded with plasq's Skitch!
(Note the above illustration is not a Finder Window. It's the dialogue you get when you go File -> Open)
You can access the Library from the New Message Window in Mail:
Uploaded with plasq's Skitch!
*For users of 10.4 and later* ...
Many internet sites such as Flickr and SmugMug have plug-ins for accessing the iPhoto Library. If the site you want to use doesn’t then some, one or any of these will also work:
To upload to a site that does not have an iPhoto Export Plug-in the recommended way is to Select the Pic in the iPhoto Window and go File -> Export and export the pic to the desktop, then upload from there. After the upload you can trash the pic on the desktop. It's only a copy and your original is safe in iPhoto.
This is also true for emailing with Web-based services. However, if you're using Gmail you can use iPhoto2GMail
If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
*If you want to access the files with iPhoto not running*:
For users of 10.6 and later:
You can download a free Services component from MacOSXAutomation which will give you access to the iPhoto Library from your Services Menu. Using the Services Preference Pane you can even create a keyboard shortcut for it.
For Users of 10.4 and later:
Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
Other options include:
1. *Drag and Drop*: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2. *File -> Export*: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
3. *Show File*: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
Of course you should have a back up of your Photos too.

Saving RAW edits as JPEG - is it okay if...?

Just wanted to get some expert opinion on whether saving RAW edits as JPEG is advisable.
I understand that every time you save a JPEG, there is some loss/degradation, whereas TIFF is loss less. However, given the huge size of TIFF tiles, my thinking is that saving them as JPEG is okay as long as if I want to make subsequent edits, I revert to the original (RAW) and re-do the edits.
Is there any downside to this logic?

iPhoto does not keep resaving the same JPG over and over. Instead it applies the new edits to the original file and recreates a new JPG. So no matter how many times you edit the file, you are only one generation removed from the RAW file.
iPhoto keeps tracks of your edits in a list and reapplies them when you open the file to view.

Convert Firework layers to individual powerpoint graphics

Hi,
Is there a quick way to convert a fireworks png document that has multiple layers into individual graphic files in powerpoint?
I'm looking to make the powerpoint interactive by linking each graphic with a separate slide when you click on the graphic.
Thanks.

Interesting idea. I'm not very familiar with PowerPoint but I suspect it's like Word in that it mixes vector-based type with bitmap graphics, whereas Fireworks' output is purely bitmap (unless you're converting to HTML output). Therefore, any text elements might appear more smoothly rendered if created directly within PowerPoint rather than Fireworks. (This is just a guess.)
Fireworks' output options are available under File > Export and File > Save As. This is what you have to choose from:
Based on your description, it sounds like "Layers to Files" (in the Export command menu) may be the best option. Before you export, you might want to select an appropriate image file format using the File > Image Preview command. PNG32 is a good all-purpose choice. (Click "OK" to save your settings without actually exporting.)

How do I export Layers to individual Files?

In Photoshop CS, there is a script that exports Layers to individual Files.
Go to File>Scripts>Export Layers to Files.

Hi Arien,
If your animation program supports paste open it and select each layer,
Select>All, Edit>Copy and paste that layer into that program.
If your animation program doesn't support paste you can paste each layer
into a New file and save it as a *.png image.

How batch export layers to files in CS5

Hi,
I am a newbie in CS5 , I tried to batch export layer to files in CS5 , because I have thousands PSD files that I need to export layers in separated png files..
In each script I made I have the following error.." reference error: dlgMain is not found" ( in french: erreur de reference: dlgMain n'est pas definie)
How can I batch export layers to files in CS5??
Thankyou all by advance for your help.

I am humbled to be of any help. I truly believe you are one of the unsung heroes of the Photoshop community!
I lost track of how many custom and ingenious scripts you created for countless other users, in so many online places...
As a scripts Illiterate, I bow in front of your knowledge and generosity!
(But Learning After Effects Expressions might in fact made me begin to make tiny steps towards wrapping my head around scripting)

All my saved layers disappeared. Shows only one locked black layer.with red sripes

All my saved layers disappeared. Shows only one locked black layer.with red sripes

Apple changed the save behaviour several times in the past few versions of MacOsX - there is a good article about this:
http://www.macobserver.com/tmo/article/os-x-mountain-lion-how-apple-rescued-save-as
The trouble is, you should (I know, not much of a help to you at this point) always create backups AND work with versions. So save many versions (x1, x1a, x2, x2a, etc), because when you work within one master file you run the risk of these type of accidents and there is always a tiny change your file becomes corrupt for some external reason. You never know. Disk space is cheap, losing your work is often a real hassle, and can become very problematic when dealing with clients.
So, save many versions, and make backups of your work. And never NEVER open your original files in any other software - always use a duplicate. You never know what that software might do to your files.
Anyway, have you tried searching for the file name on your mac? Maybe, just maybe there is a duplicate lying around somewhere with the layers intact.

I have put the like var exportPath = "~/Desktop/Backdrops/png/"; and have removed the exportPath = exportPath + '/layers';
but when i run the script it still comes up with the error
could not complete action since the destination folder does not exist
if you are using the extendedscript toolkit would be able to run the script and see if you know were the problem is coming from i cant seem to understand why its not seeing the destination.
thanks for all your help

Saving out .tiff to .jpeg using "Save As"

Hi peoples,
I hope you can help me with this saving out issue i have,
If i open a .tiff from lightroom into photoshop cs6 with LR adjustments, I click "save as" .JPEG in a new location, I am now editing the .jpeg and not the tiff.
Yet if I open the same .tiff from file explorer and not LR and "save as" .jpeg in a new location, I am still editing the .tiff (This is what i want because i want to create an action which will save multi jpegs into different locations, with various color profiles, i want to ensure these jpegs are the best quality possible, therefore i want them saved from the .tiff as the source and not another .jpeg!)
Hope you understand
Thanks for your help

No in both cases your editing a Photoshop Document. Photoshop is not a file editor. It open files into a document and it save files from documents. When you save a file the document you were exiting is still open in Photoshop. The document may have layers Tiff file camnalso have layers however if a tiff file is layered LR can not handle these layers it does not support layers. I have no use for lightroom one reason is it lack of layers support.

Again Photoshop Open files into documents and works on documents. If you use save as and save a Jpeg fron a document you opened from a Tiff. The Save As would not delete the Tiff file there would be two image file on you disk for the image, The original Tiff file and the new saved jpeg. The image may or may not look the same it depends on what you did in Photoshop before saving the jpeg and wither or not you also save out an updated tiff after you saved the jpeg.

Saved layered .psd files display text in preview column

Hi,
I have layered files that I have saved. When I view my files in column format, in the preview area, text appears, not the image. I can't read the text as it is so tiny. Even when I magnified it I couldn't red it. It just seems to happen to files saved as .psd, not to jpegs.
Has this happened to other people? If you have a solution, other than flattening the file, as I wish to save the layers, please help me. Thank you in advance.

>When I view my files in column format, in the preview area, text appears, not the image. I can't read the text as it is so tiny.
Meaning you are previewing in the Finder?
That is possibly because you have an Alpha channel in the file.
If you learn to use Bridge CS4, instead of using the Finder, you won't have this problem.

Saving edited photos in jpeg

I use Element 9. I am not alowed the option on the drop down list to select jpeg when saving edited photos. Please help!

Make sure the image is not 16 bits/channel and not bitmap or indexed color.
Image>Mode
Usually RGB Color and 8 bits/channel is the norm for saving as a jpeg.
Also if your document has layers (jpeg doesn't support layers) you would need to flatten the photo before being able to save as a jpeg.
If you want to keep the layers use a format such as psd or tif.
