Problems with Photoshop Alpha Channels
Hi all
Got a job where I want to use alpha channels to cut-out some images in Photoshop and then put them into an ID frame with a black background. Want to use alpha channels rather than a clipping path as I need the edges to be feathered (have applied 2 pixels of feathering to the selection in Photoshop before saving it).
When I do this and drop it into Quark it looks good but when these images are dropped into ID and then the alpha channel is turned on, with the default Threshold and Tolerance settings, it doesn't look good. It looks like a rough approximation of my alpha channel, all the fiddly bits and bezier curves in the selection have been smoothed out and the feathering has gone. Playing with the settings doesn't really seems to help either. If I turn on the alpha channel in the import options when importing then it comes in as expected but I have quite a few images already in the document that I need to turn on the alpha channels for.
Both PS and ID are CS3. I've tried saving the images both as PSD and tif. Anyone got any ideas? Seems odd that when I import an image with the channel on I can't go to the clipping options and tweak the settings.
thanks,
Iain
Thanks for your reply Bob. I've confused things with my terminology I think. We're drawing a path round the image, using bezier curves where appropriate, making that work path a selection (feathering the edge in the process) and then saving the selection (as an alpha channel) and then using the feathered alpha channel in Quark/ID to knock-out the background. Not keen on using a PSD with a transparent background at the moment as these are just test files while we show the customer what it will look like if we do cut-outs. We are making a couple of different alpha channels per image, with different settings, which would mean multiple files if we used your method I think. Maybe once we get the approval from the customer we could use PSDs as you describe but I was just wondering why the options for affecting alpha channels after importing the image aren't working as I expected.

How do I save a PNG file with an alpha channel in Photoshop CS5?
I have a PNG file created in Photoshop and I need to save it with an alpha channel for web purposes. I tried 'Save for Web & Devices' and selecting the Transparent box. Then, after saving, when I select 'get info' for the file it says there is no alpha channel. I'm stumped I can't seem to create an alpha channel from within Photoshop while I'm editing. Help!
If you save as a 24bit png with transparent checked photoshop will save the png with transparent background (ie alpha transparency). The png will appear transparent in a web browser.

Exporting SpeedGrade Project with Embedded Alpha Channel
Hello! I am currently writing with a problem I can't seem to find a solution for in SpeedGrade. My problem is that I imported footage with embedded alpha channel enabling me to chroma-key out a green screen. I would like to export this file now with the alpha channel still embeded to be delivered to Premiere. Is this possible?
Your help is greatly appreciated!
PhilipThanks Fran,
I'm using uncopressed QT, animation.
I did the color correction on a grading track and I think that's what killed the alpha, because when I selected the track with the footage the alpha was being read properly. So what I did instead is I saved a .look file and imported it in After Effects, I rendered from there.
Can you have the grading track read the alpha from the original footage or if not can you copy the attributes from one track to another, as if I was moving all the grading from the grading track to the footage tiself instead of having to do it again from scratch?
Thanks again,
David. -
Encoding with an Alpha Channel Using Quicktime Pro
I am pulling my hair out trying to encode a green screen video that will play on a website so the website shows through the transparent alpha channel. Problem is when I encode to .flv or .mp4 the alpha channel is never retained even when I check "encode alpha channel" in the .flv export setting window. I have downloaded a trial version of Sorenson Squeeze and even that couldn't retain the alpha channel.
The video I am using was exported out of Final Cut Pro 7 using Quicktime Conversion using the Animation Million of Colors PLUS codec and when I test that it does indeed have a transparent alpha channel so something is happening when Quicktime Pro is encoding it.
Can anyone recommend a way to export a .mp4 or .flv with the alpha channel?
Thanks in advance for any help you may be able to give.
Benjamin JonesYou can also export a RGB video (without alfa) with any codec, and a second pass with obly alpha - it depends if you need that as a final export (then use codec than can export alfa) or intermediate format (then you can use image sequence or 2 pass video).

Problem with Photoshop CS4 after migration to new Mac
I just migrated from an old Mac to a new Macbook Pro running Mavericks. I'm having a problem with Photoshop CS4. Specifically, two things:
1) When I open an image in Camera Raw, I get this error:
Fatal error - missing component
/Library/Application Support/Adobe/Adobe Version Cue CS4/Client/4.0.0/VersionCue.framework
2) When I try to save anything, it tells me it can't because of a program error.
I've looked around for a solution. Apparently I had to install Java, but that hasn't solved the issue. A couple of people mentioned that reinstalling would work for a similar problem. My problem with that is that my disk is on the other side of the world and my new macbook doesn't have a disk drive anyway. So I logged into my Adobe account hoping to see a download link for software I have licences for, but there isn't one.
So my question is firstly, whether there is a simpler solution to the errors I am getting and, if not, if there's a solution to reinstalling Photoshop CS4 without the disk.
Thanks!Did you use Apple's migration tool? It misses a lot of support files, especially in the Application Support directories.
You'll have to copy those files manually, or reinstall the app. -
Problem with Photoshop CS6. If I open a file using Camera RAW
I have a new problem with Photoshop CS6. If I open a file using Camera RAW, and process it as usual, CS6 doesn't want to save it the way it used to. I don't know if I changed something by accident or not.
Here's what happens now: After opening from ACR to CS6 and completinhg all of my work, I choose "Save as..." The save as window opens showing the file name and format. The default format seems to be .PSD. I use the drop down to select .jpg. The file saves normally as a .jpg. When I go to close the image from, I get a new prompt asking, "Save changes to Adobe Photoshop document DSC_xxxx.NEF before closing?
I looked up at the file name in the bar above the work space and noticed that it does NOT change from "DSC_xxxx.NEF" to "DSC_xxxx.jpg" after I have saved the file as a .jpg,in my webesite but it always used to do that. This adds a few extra steps when closing a document and it really slows me down.
In fact, I wouldn't swear to this, but I think it used to save to .jpg by default, without me specifying this.
I don't see a setting in the preferences for what to use as the default file format for saving, so I don't know where to change it back.
Any ideas?

Problems with Photoshop CS2
I originally purchased this software several years ago. At time I was running Microsoft Windows XP.
This computer recently was replaced with a Dell running Windows 8.I reloaded my CS2 on this computer & it ran fine with a few exceptions as follows;
when the software comes up initially I get a message that says “could not complete your request because of program error”. Hitting OK allows me to continue using the software .
When I try to activate a function using CTLR or ALT keys I get this message “required application failed to load and the product cannot continue. Please reinstall the application”. This causes the application to abort.
Reloading my CS2 continues to generate the same messages when I depress the CTLR or ALT keys.Your original copy is obsolete and Adobe is offering a free replacement you are entitled to. Download and use that and that should clear it up for you.

Help with add file name problem with Photoshop CS4
Frustrating problem: Help with add file name problem with Photoshop CS4. What happens is this. When I am in PS CS4 or CS3 and run the following script it runs fine. When I am in Bridge and go to tools/photoshop/batch and run the same script it runs until it wants interaction with preference.rulerunits.

You can turn that off in photoshop cs6 under Window>Application Frame.
If that's not it, could you post a screenshot? -

We have version 10.5.8 photoshop CS3 for Mac. How do we fix a problem with photoshop not resizing dpi? For example we resized a 72 dpi image to 200 dpi, when we do a pdf analysis it read as 344 dpi.
Sounds like it's a problem with the Acrobat settings. Did you set them to the same resolution?

Problem with Photoshop Elements Printing
I have been using Photoshop Elements for a couple of years now and know it pretty well. Today while attempting to print, a strange problem came up: After going through the protocol to make a print, just before the image prints PE does a very fast auto correction that basically ruins all the color correction I have made on the image. How do I disable this function?
Hi and thanks for your reply. I checked the settings under "Print", "More Options", then "Color Management" and it only has "Print Space", none of the three options that you said I should have. Am I looking in the wrong place?

Check your color management by clicking More Options in the print dialog There are basically three options:1) Printer Manages Color2) Elements Manages color3) No color Management Make sure everything is consistent e.g. if you choose Elements manages color make sure color management is switched off in the print driver.

Problems with Photoshop CS5.1
Hello everyone, I'm having some problems with Photoshop, it simply doesn't work as it should. When trying to resize the brush, the cursor changes shape and if I click, it won't, for example, paint where the cursor is pointing at, but about two inches diagonally. Then, the liquify tool freezes and I have to zoom in/out in order to make it work again, the brush disappears when changing the size, and again the cursor changes into something else and doesn't make any adjustment to where it's pointing at, but to a lower section. It's annoying to keep working like this! According to the update manager, everything is up to date. My current OS is Lion 10.7.2. Does anybody know how to fix this or at least why it is happening? I asked in the Adobe forums and I was told that it was Apple's fault (obvious response haha), and that a software update should come up to fix this driver problem or something. I'm not sure of what this is but I can't work like this. Thank you in advance.
What it means is Adobe is feverishly working on a solution. Apple has no control over Adobe's products. They may make spec changes to allow for better support of other data formats, and the GUI, and security of the operating system, and Adobe is always in the loop on http://developer.apple.com/ If they can't make Lion work with their software, it is partly due to the immense size of their software and not being able to modify such software without significant error checking, and partly due to possible changes that Apple may have made. One should never upgrade a production environment until one knows all one's software is compatible for all one's needs. Having a test machine, or a test hard drive to see if an upgrade works is probably best until migrating an entire environment to a new system. And always backup your data prior to upgrading. A clone backup offers the quickest recovery time. Carbon Copy Cloner is a great solution for external hard drives, and so is Superduper.
