Trouble making parts of image transparent in Photoshop CS3

I have an image which is currently surrounded by a white background that I want to get rid of.
So far I have selected all of the background and hit delete, which appears to have deleted all of the white background as it shows up transparent.
However when I save the image as a TIFF an then open it up in Illustrator, the image still contains the white background.
What am I doing wrong?

This can't be done on a Background Layer. Promote it to a real layer by double clicking it in the Layers Palette. It suggests "Layer 0", which is fine.
Then you can successfully delete the B/G colour. Did you see the chess board pattern?
Maybe export as PSD or PNG before opening it in another application?

White Lines appear on Images in Adobe Photoshop CS3

White Lines appear on Images in Adobe Photoshop CS3
Recently discover that on three different computers, while editing images in Adobe Photoshop CS3, white lines would appear on some of the images.
For example changing a image from a .jpg to a .psd or size, or enchantment features, the white lines would appear on the image.
The lines did not appear on any of the printed images, any suggestions.
Monitor: Sony Trintron Multiscan G4110
Computer: Mac G5

>The lines did not appear on any of the printed images,
Although it is odd that three computers exhibit the same problem, and unless you can provide other coincidences (same files, same monitor, etc.), I agree. The video card is typically the culprit IF the image anomalies don't print and if they move about with each image resizing or opening of a specific image. Check to see if it's properly seated and connected. Same for monitor cable. Try swapping in another card.
One other thought: as this is a CRT monitor, what happens if you change the resolution and refresh rate? Are you using a recommended combination for that monitor?

Is there a way to make images transparent in Photoshop Elements 12?

I just purchased the new software and don't have any experience with this program. I'm trying to find out if I can make the background of images transparent.
Does anyone know?

Yes. First you must double-click the background layer to convert it to a regular layer. Then use whatever selection tools are appropriate to select your background and press delete. Unless you've you've changed default settings you should see a grey & white checker pattern - this denotes transparency.
When saving you must save it to a format that supports transparency. For GIF and PNG use the File> Save for Web and make sure the transparency checkbox is ticked. For TIF use File> Save As and select the TIF format. On the same dialog that offers compression options, there is a transparency checkbox.
Cheers,
Neale

Colours change badly when LR2.5 image sent to Photoshop CS3

When I right click in LR on an image and "edit in CS3" the image opens in CS3 with a horrible magenta and/or blue colour cast that is difficult to remove.
I have set LR to export in AdobeRGB, and CS3 edits in AdobeRGB.
This is new behaviour, since I got a Canon 50D but I assume this is coincidence.
The effect is variable, worse on some images than others, so I can use no automatic workaround to fix the shift.
It is ruining my workflow. I've searched on everything I can think of in forums and help.
- Win XP SP3
- both screens calibrated with GretaMacbeth Eye-one
I observe that:
a) even the dialog boxes in the two programs have completely different colours, not sure if that is supposed to be so.
b) CS3 says that my CS apps are not sync'd for consistent color. I don't know what other apps I may have, or why this is so.
Attached -
- my external edit prefs and CS3 colour settings
- sample image screen capture in LR
- same image screen captured in CS3
Thanks

This seems to have died. I've answered a few questions but no responses to those reqested infos, and no answer forthcoming.Some responses suggest that my post has not even been read properly and the only suggestions made have been inappropriate to my posted info.
Can anyone tell me how I get effective help for Adobe products? I am more than jaded with the facts that:
- Adobe software in general and Lightroom especially has almost useless help files/website. Adobe seems to rely on a) 3rd parties and b) a collection of informal only sometimes professional often independent (uncoordinated) resources that are as disparate as they are confused to provide help and usage training. The help available from "Help" menu item is incomplete and often, if not mostly, missing the point for which you are seeking info.
- Adobe software including Acrobat reader (inside Firefox), CS3 and Lightroom are the ONLY softwares that crash my system or do not work reliably.
- Adobe phone and email support is entirely, completely and fully useless for anything beyond certain standard problems. The only offered solution to anything I've ever rung or emailed about has been "uninstall and re-install" after demanding enormous amounts of information that was probably irrelevant or ignored but consumed considerable effort and time to provide.
- when you DO uninstall and reinstall Photoshop, you find it is the only software I know of that routinely loses all your settings and actions in the process.
- and so far, uninstall and reinstall has never resolved any Adobe problem on my machine.
- Adobe more than any other provider seem to rely on new PAID upgrades as the suggested means of resolving bugs and other problems that are intrinsic to the software, and Adobe don't continue to maintain older versions.
So - here I am with what is to me a serious problem, and I have no visible means of useful tech support.
People like me are always being criticised on these forums for being cross and frustrated, with smooth talking smug folk saying that you'd get better results if you were polite. The trouble is it is difficult to remain polite when you see no available solution, a lot of time taken up and no APPARENT determination by Adobe to provide support that actually meets people's needs, or at least people with non-standard problems.
I don't believe I've been rude here, but it's now 4 days and I'm no nearer to solving the problem.
Could someone suggest how to get effective help with this problem, or other problems from Adobe?
Thanks

Preserving Transparency from Photoshop CS3 to Illustrator CS3

Hello all,
I'm trying to figure out how to preserve an image's transparency between Photoshop and Illustrator. Both apps are CS3.
In the broader design context, I'm trying to move an isolated wine bottle from Photoshop into an Illustrator document. I'd like the neck of the bottle to overhang a series of dotted lines in the Illustrator document.
Any help would be much appreciated.
Thanks

double-click the background layer, so that it becomes Layer 0, or whatever you want to name it. Background layers are not capable of transparency, so you have to make the layer into a non-background layer.
A more flexible way to do this; instead of *deleting* the area you want to be transparent, while the selection is active, click the "make layer mask" button at the bottom of the layers panel. This is non-destructive to your original image, and can easily be edited or tweaked in the future.
I highly recommend learning to use layer masks while you are learning to use layer transparency. I'll bet Doug would recommend this as well.

Need help in quantizing an image(using adobe photoshop CS3)

Hi All,
I am using window and adobe photoshop CS3 extended. I had an image whereby i had already perform histogram equalization. I would like to quantize the image obtained into 2 bits per pixel, per channel. Can anyone advise me? The image is a 24 bit colour BMP file whereby the bit depth is 24 bits. Pls advise.

Hi, I managed to find the refresh cached option. However there is still one thing which i need some clarification on.
The problem for me is to quantize the image into 2 bits per pixel per channel. I understand from the previous post that i need to use posterize and set it to 4. My questions are as follow.
1) why must the value be 4? if the value is 4 then there should be 8 bits, but my question require a total of 6 bits only
2) After saving my quantized image, the properties of the image still show me the bit depth being 24, thus is there any where whereby i can check that each color pixel is exactly represented by 2 pixels?
Hope you can advise. Tks

What's the right format to make part of image transparent in LiveType?

Does anyone know what format an image needs to be in to make the white in a logo transparent? Do I have to create an alpha channel in Photoshop or a transparent GIF or something like that? Thanks!

I've never tried it in LiveType but Targa (.tga) files are your best bet. I think PNGs will do it as well (or at least support transparancy)

JPEGs Created In Photoshop CS3 Import As Black Images

Is anyone else having problems bringing images from Adobe Photoshop CS3 into iPhoto? I am creating grayscale and color (RGB) images in Photoshop and then dragging them into my iPhoto library for import. Some come in just fine. Others have black thumbnails and when you open them to view them, they are like negatives.
Any ideas?
wncmacs

David
iPhoto does not support greyscale and they will display "like negatives". Convert them to RGB and they will display fine.

Trouble saving Photoshop CS3 files to server

I've recently upgraded to Leopard v. 10.5.2, and now I'm having trouble saving any sort of file through Photoshop CS3 to my company's server. Even after opening the file from the server, when I try to save it, I get an error message saying I do not have the privileges to save the file. And I've saved the file to my desktop, and tried dragging it to the server folder, and I get a slightly different message, but with the same problem.
I can save jpegs that weren't created with Photoshop, but not vice versa. My other CS3 programs save files like normal. It's just Photoshop.
One way I've found to get around the problem is to email the file to myself, and then transfer them to the server. But this is an annoyance. Thanks for any help.

I would like to know how Adobe can make their uses download the OS X 10.5.3 update without sorting out the photoshop bug. Why should we not be able to save our files directly onto reliable servers. You would think that by now the concept of saving a file to a network disk would have been solved. Saving directly on servers worked flawlessly for me - why not now? I have never had this problem before until this OS X 10.5.3 update. This is appalling as designers save their photoshop files onto a server so that other designers may access their files. Yeah I will now work locally and transfer the files across. Last night I realised that I could not open many files that I had worked on during the weekend - I have lost hours of work and am feeling pretty devastated. How can Adobe not even warn their customers about this problem!!!! Don't fob your customers off. This is HUGE BUG - I've paid for my software so fix it!
I wonder how many designers have this problem and don't even know. Abode should be letting their customers know about this BUG before they have to find out themselves after having lost irreplaceable work.

Photoshop CS3 Won't Open Files in Windows 7 64-bit

Hi All,
I'm running Windows 7 64-bit on my desktop. When I try to open an image file in Photoshop CS3, the program hangs and never opens it. I have attemped PSD's, JPG's, GIF's and PNG's.
I have right-clicked on the program and selected to run it as an administrator. I have set up a compatibility profile as Windows XP SP3. I have tried both at the same time and there's been no change.
Any thoughts how I can conquer this beast??
Thanks!

Change the default printer to something local, and that you know is available (either a PDF print, or an attached printer).
The most common cause of this is a remote printer that isn't available, and the driver takes it's sweet time returning.

Lightroom 2 - Photoshop CS3 - Lightroom 2

Here's my scenario.
All RAW files have been converted to DNG.
I would like to catalog all DNG files in Lightroom (thus, starting my workflow there). If I shoot an ISO 1600/3200 shot, I would first like to run it through Noise Ninja in Photoshop CS3. So I right click on the Image, Edit in Photoshop CS3 (I have both Edit and Open as Smart Object as choices - unsure which is the right one to use). I can want to run Noise Ninja over the image to remove some noise, and then return back to Lightroom (WITH that change) for further editing. Creating new files (like a PSD) to accomplish this isn't a big deal.
I just don't know how to do it! The image in Lightroom after running Noise Ninja still shows noise.
I've tried the above, saved the PSD, but Lightroom appears to ignore it. Does it matter what the file is called? Does it matter where it's located? How do I tell Lightroom to acknowledge the change?
Any help (step by step) is appreciated.

I figured out how to create an action, make it a droplet, which creates an exe, and reference it via Lightroom. Now I can Export in Lightroom, run the "noiseninja.exe" droplet (needed to make it "run as administrator" in Vista), and have a .psd auto-imported into Lightroom's catalog. Works pretty well (and fast).
I end up with two versions of the same image - one the original .dng, the other a .psd. Which I understand the reasoning for.
Here is what I don't understand:
When I use Export, the .psd is named the same as the .dng file (CRW_2593.dng is imported as CRW_2593.png for example). If I then go ahead and "Delete from Disk" the CRW_2593.png file, both the .png AND.dng files get deleted! These files are not stacked, one only was selected, etc. This doesn't seem right (as I lose the .dng file by deleting the newly generated .png).
Here's something a bit interesting. If I go ahead and "Edit in" the .dng file (after restoring it from a backup), and use the same droplet (set up via Preferences/External Editing), I will also get a .png automatically added to the Lightroom catalog, though it's name is a little different (CRW_2495-Edit.png in this example). I'm presented with a dialog box before conversion which forces me to "Edit a Copy with Lightroom Adjustments". If I go ahead and "Delete from Disk" the CRW_2493-Edit.png, the original .dng stays! I assume that the "Edit a Copy..." above makes it this way.
Is there a way to make the "Export" function behave the same (with regards to the "Delete from Disk" feature) as the "Edit in" function? I've been through the screens for Droplet and Export a dozen times and don't see any setting that refers to the .dng and .png being linked.
Thanks,
-Craig

Making certain parts of an image transparent laying it on top of another

I am currently doing an MSc project, where I am simulating the behaviour of ants in Java, however I have hit a stumbling block. Currently, I have an AntTerrain class that contains a paintComponent method. Every time this is called it draws a BufferedImage of the terrain which consists of all the obstacles and food, over which the ants are drawn by iterating through a 2D array. I have been trying to implement pheromones into the simulation, and although I am able to do it I want to have the functionality to be able view or not view them. Initially I had two Buffered images, one containing all the terrain information and the pheromones, and one not containing the pheromones. This became rather costly as the simulation progressed and more pheromones were laid, so recently I have been trying to create a buffered image of just the pheromones which I can overlay onto the terrain as and when the user wants to.
This has been causing me immense problems. I have had limited success with using the alpha channels of the terrain image, by making it almost completely transparent, then drawing it on top of the terrain image, by setting the compositing to SRC_OVER, however, this muddys the terrain image below.
I have been looking up various books and documentation on line to try and work out how to do it in a more elegant fashion without success. Peter has come up with the idea of using either Regions of Interest, Bitmasking or a combination of both. Neither of these techniques have been particularly well explained in the documentation I have found and I am more confused than when I started. Any help you could give me in this matter would be greatly appreciated.

If the pheromones can be drawn independent of the array of ants then I would use a single BufferedImage and make a new one for each user change of pheromone visibility. If this is to unwieldy of if the pheromones require the ant array then I would try an OverlayLayout with the BufferedImage of obstacles/food/etc on the bottom and the pheromones on top. The ants could go on either one; maybe they would look better drawn above the pheromones on the top layer (guessing...). If you want to draw the pheromones with an AlphaComposite and they would look okay drawn above the ants you could draw the ants below and the pheromones above. This would be easy and fast.
Here's an example of the OverlayLayout option:

How do I remove white jagged edges after making image transparent?

How do I remove white jagged edges after making image transparent? Is there a feature to help out with this?

It's a file format limitation. GIF supports 1 bit of transparency. That is 2^1 (which equals 2 total) levels of transparency. This equates to either NO transparency at all, or specifying 1 single color of the 256 total possible values to being fully transparent.
This will leave a very ugly fringe around the edge no matter what; it will only not be visible in color that match or are close to the fringe color; and then, that's a perception issue.
Try creating an alpha channel and saving the image as a PNG. That supports 8 bits of transparency, which equals 2^8 or 256 total different levels of transparency. This will let your image have very smooth edges with no jagged transitions.

PhotoShop CS3 Transparent Image Export

In Adobe PhotoShop CS3 Windows version where is the "export as transparent image" feature which was there in the Help Menu earlier? Or is there some other of achieving the same result?

That's baloney, Ed, "IMHO."
Most of us don't fully understand how Photoshop goes about applying JPEG compression algorithms. By your reasoning it would be "improper" for us to save files as JPEGs. I'm just glad that this functionality is built in so that I easily take advantage of the functionality.
Of course there's added value in knowing how to save an image in the format best suited to one's purpose. But the people who miss the wizard are just looking for functionality that has suited them well in the past. What authority do you have to deem this "improper"?
