Beginner question: retaining color on a portion of a photo

I know this is a reletively easy function in Photoshop, but I wondered if it is possible in Lightroom to reduce color saturation to zero in only selected portions of a photo. For example, to have a black and white portrait with blue eyes.
Is this possible? Thanks in advance for any assistance.

Excellent tip ...
Alan.
PS - Message for the OP ... stick around, even after using LR for a while and regardless of how many posts you make here, there is always something to learn / pick up.

Using Color From One portion of a Photo to Correct Color in a Faded Area

I'm a complete noob with photoshop elements 10. The more I look on this forum and in help the more confuesd I get. Here's my problem.
I have an old photograph that has faded from expoesure to sunlight. After removing the photo from the frame there is about a 1/2" portion around the entire picture that isn't faded and has correct color. How do I tell Elements to use that area with the correct color as the basis for fixing the faded portion of the photo?

There's one trick you can try to automate the process somewhat:
Make a duplicate of your original photo, and do all the remaining stuff on that duplicate photo so your original photo is safe.
Open the duplicate photo in PSE.
Use the Rectangular Marquee tool to select the faded area.
Use Edit...Cut to place the faded area on the Clipboard.
Save the image with the remaining "frame" area.
Use File...New...Image from Clipboard to create a new image with only the faded portion, and save it.
Use File...New...PhotoMerge Style Match.
At the bottom of the StyleMatch editing screen, click on the "Project Bin" tab so you can select your opened file to use.
Adjust the settings to suit.
The Help has more info about Style Merge:

You'll probably still need to do quite a bit of hand work, but that might give you a good starting point.

How to color correct a portion of a photo?

I am new to photoshop. I have version cs5. I have several photos that were taken through a Blue tinted plexiglass window.
Some or all of the photo has acquired the tint. Also parts may have a reflection minor of people standing around.
How do I remove the tint?
Please be as specific as possible.
Thanks for the help.

One comment, when shooting through any window/transparent object is to shield the area, that you are shooting through, so that there are no reflections. This technique is used, when shooting through "the glass" in a hockey arena. There are even special lens shades, that look sort of like a small lightbox, that fit up to the plex, but still allows one to alter the angle (a very flexible connection near the lens' outside mount). Now, that will not affect the "tine," unless that is coming from behind the plex, like a reflection of the sky.
Good luck,
Hunt
I carry a rubber lens hood that fits up against the glass. An almost essential accessorie when visiting places like zoos. You can even get away with using flash!
ibuster, your image is not an easy fix being quite so blue as it is, and with it being local to only some of the image, you are going to need to understand Layer Masks.
A good first step is to go Image > Adjustments > Match color and click on Neutralise.
It is probably going to be easier to use Levels adjustment layers rather Curves, so
Open a Levels adjustment layer
select the Lasso tool, and click on one of the corners of the blue tint.
Hold down the Alt/Opt key, and click on the next corner, and so on until your selection surrounds that segment of blue tint.
Now do the same for the next blue segment, but hold down the Shift key for the whole time you work round the segment. This will add this segment to your previous selection
Repeat for the other blue segments.
Now click on 'd' to make Black your forground colour, make sure the Levels adjustment layer is selected, and go Alt backspace (Opt backspace if using a Mac)
This is actually the opposite of what you need to so go Ctrl/Cmd d to turn off the selection, and Ctrl/Cmd i to invert the selection. Your adjustments will only affect the blue segments now.
Right. It is not easy to give you a step by step here, but a good first step would be to drag the end points of the Levels adjustment layer in a wee bit from both ends to restore the contrast to the blue segments.
Now make a decision on which of the Red, Green, Blue channels is out of sync, and use the drop down to select that channel. Place your cursor over the 1.0 in the center of the Levels, and using the cursor keys, nudge its value up or down.
I am afraid it is not an easy fix, and you will be messing around for a while, and probably never get a perfect result, so good luck to you. As you can see from my quick fix, the problem is not uniform across the segments, and would take multiple adjustment layers and careful masking to get a really good result. I am not a Retouch expert either, so there may be easier ways to fix it - www.retouchpro.com would be a good place to ask for specialist expertise.

How to fix gray background on images without checking "retain color depth"

I have a cover page on my report where the user can insert a logo image. The problem is that if the logo image has a white background it will turn the white background gray. I have figured out how to resolve this by checking "retain original image color depth.u201D The problem with this is that all the images in my report are larger so the report pdf file size goes from 3mb to 30mb. Is there a way to make the logo image appear as normal without having to check the retain color depth? I have tried adjusting the image in photoshop several different ways but havenu2019t figured it out yet.

That is exactly why the option is there. And why it is unchecked. Most people prefer to have smaller report size. The choice is small reports with the option unchecked and the loss of picture quality, or bigger reports with the option checked, retaining the picture quality. THis a by design and is not consiered to be a "bug". If you post the issue into the [idea place|https://ideas.sap.com/community/products_and_solutions/crystalreports] perhaps it will get picked up as an enhancement, but that it the best I can suggest.

Converting MS Office Suite products to PDF - not retaining color

I am using MS Office suite (2003) specifically MS Word & Visio. When I convert to PDF (using Professional 8) it is changing my color documents to black and white. I have tried all different settings and have marked the selection to retain color scheme. Nothing seems to work. I checked my settings against another colleague and they are the same, but for some reason my version will not convert in color. Please HELP..

It's happening the same way on several different computers here.
Everyone logs in with their own userid on each machine. We are all working with the same MS WORD documents. These documents are non-standard sizes -- 6 x 9, or 5.5 x 8.5.
Everyone uses the same version of Acrobat Professional, and selects "Convert to PDF from file".
For some people, the PDF is created from the Word doc, and the original page size is retained. This is what we want.
However, for others, the PDF is created as 8.5 x 11, no matter what the original size of the document was. No amount of fiddling with the default page size, in either Acrobat or Word, changes this.
It is driving me crazy, and I was hoping that at least one other person on the planet has come across this problem. Is this an Adobe or a Microsoft problem? Could it be a Windows registry setting?
Advice is appreciated!

Question About Color's and Gradients

Hi all,
I have a question about color swatches and gradients.
I am curious to know, if I have 2 color swatches that I make into a gradient color, is it posible to change the tint of each indivdual color in that gradient and have that applied to the gradient without having to adjust the gradients opacity.
The reason that I'm asking this is because in creating a project I found that the colors that I chose for to make my gradient from my swatches were to dark, and while I can adjust each one's tint to my liking (if the object they were applied to was going to be a solid color) but that doesn't seem to apply to the overall gradient.
I hope that makes sense, I know that this was something that was able to be accomplished in quark and was wondering if I can do something similar.

If you double click your gradient swatch (after adding it to the swatches)
Then click a colour stop in the gradient, and then change the drop down menu to CMYK (or rgb)
And you can alter the percentages there. It's not much use for spot colours but it's a start.
But making tint swatches would be a good start anyway.
At least then when you double click the gradient (in the swatches) to edit it you can choose from CMYK, RGB, LAB, or Swatches and adjust each colour stop to your liking.

Beginner Question

Hello all, hopefully I have posted this to the correct LiveCycle board!
I'm new to Acrobat and LiveCycle in general. I'm working out of windows LiveCycle Designer 8.x and my question is as follows....
I'm working off of the "Quote" Form Template and what I am looking for is a way to make the rows of the Table expand as needed. I will be converting this Template into a "Purchase Order" form, and there will be many occassions where I will need to increase the table rows - perhaps onto a second or even third page - due to the volume of different items I will be seeking prices on at a given time.
Long story short I would like to take this "QUOTE" form template and make it such that if needed, I can expand the table size one row at a time, pushing the content beneath (Comments, subtotal, etc) onto the next page....
Hoping I have explained my query well enough, Could anyone provide me a solution or point me in the correct direction?
Many thanks!

As a followup, so as not to clog the board with numerous threads I have another beginner question
For the sake of hypotheticals I am creating a dynamic PDF form. This pdf is a Purchase Order Form, with a table in the Body that will expand/contract as the form user needs. (EXA- Default table size is 5 items, however user is creating an order for 12 items, he/she can increase the table rows to desired capactiy.) It will be a very simple layout. All data for the form will come from manual entry, no XML data binding going on.
My new question is as follows:    Is there a way I can have this user's Adobe reader or Adobe acrobat software remember previous data entries, so that if 4 weeks after ordering widget X he/she needs to place another order for widget X, the software will autofill the table as he/she types into the table cell?
This would be similar to how Excel will start to autofill if it recognizes a previously entered value from some other cell in the worksheet (workbook?)
EXA-
[NAME]   [MODEL]   [QTY]   [PRICE]
Widget           A            433        $30.00
Would it be possible for the software to notice that I'm typing the word "widget" somewhere after typing "wid" ???
Many thanks for any and all followups, I'm a teenager trying to help out in my father's small business. They are in the darkages here and I'm doing my best to self teach.
Thanks.

Beginner question: Can I apply one formula to all cells in a column?

Hi,
I'm new to spreadsheets, so apologies for asking what is probably a very simple question.
I want to apply a formula that divides the values in one column (W) by values in another (AX) for a table containing 3000 rows, and outputs the result for each row into the appropriate cell in the new column I've created.

Besides Numbers '09 Help there are two other useful resources available in the Help menu: the Numbers '09 User Guide and iWork Formulas and Functions Help.
For "Beginner questions," my first choice would be the User Guide. For the specific question you asked, a quick scan of the chapter on "Using Formulas and Functions" (pp 83-96) will provide some useful information. Start in the neighborhood of page 93.

Retain color to foreground in binary image

hi
i need some help in the java.
I have binary image whose foreground is white nad background is black by the following code
BufferedImage image = ImageIO.read(new File("f:/123.JPG"));
BufferedImage bwImage = new BufferedImage(image.getWidth(), image.getHeight(), BufferedImage.TYPE_BYTE_GRAY);
BufferedImage fgImage = //foreground image
new BufferedImage(bwImage.getWidth(),bwImage.getHeight(),
BufferedImage.TYPE_BINARY_IMAGE);
now i want to retain color to the foreground only..
can anyone help me..pleaseeeeeee

Here is my idea to display the pic on the webpage:
The pic is stored in DB as binary, after retrieving it, the binary data will be converted to JPEG pic. Then, the pic will be saved to the local machine automaticly. After that, I get the pic's SRC, and use html display it.
My code is as follow (not completed), some errors in it.     public static String getPayoffSRC(Services serv, long fileId)
                                                                throws FileNotFoundException,

        FileOutputStream out = new FileOutputStream(serv.getFileManager().getFileDb(fileId).getFileName());
        JPEGImageEncoder jencoder = JPEGCodec.createJPEGEncoder(out);
        JPEGEncodeParam enParam = jencoder.getDefaultJPEGEncodeParam(buffy);
        enParam.setQuality(1.0F, true);
        jencoder.setJPEGEncodeParam(enParam);

Beginner question regarding 32-bit mixing and mixdown workflow

Hello
I have a beginner question regarding 32-bit mixing and mixdown.
If I edit some 16Bit, 44.1kHz Stereo WAV Files and put them into multi-track view to do crossfades, how should I do the mixdown?
Audition shows me in multi-track view, that it is doing 32-Bit mixing.
Can I just mixdown to 16Bit, 44.1kHz Stereo without any dithering (as the files are 16Bit, 44.1kHz Stereo to begin with), or will I lose quality that way?
I will be performing a normalization to 96% to the mixdown and then split to tracks in Audition, as in the end I want to to have an audio CD.
I guess I could mixdown to 32Bit, then normalize and in the end save back to 16Bit, 44.1kHz Stereo WAV (with dithering, I suppose?), but I want to avoid any unnecessary converting steps.
Greetings

Any time you do any processing on a 16bit file in 16 bit only it will degrade the audio slightly due to rounding of the calculations. Working in 32 bit floating point (Audition's default) takes account of all bits generated due to processing.
So it is always best to work in 32 bit, even if your originals were 16, all the way through until the last stage of saving the files for CD burning. Any losses due to conversion will be insignificant against those due to working 16 bit.

Beginner question - how to efficiently check if a photo is part of the selection

Dear all,
Sorry for this beginner question, however I don't know how to solve it and I'm sure that there is a quick and easy answer to this:
My target is to get all the "heads of stack" (photos with Position 1 in stacks) of the selection ("photos" below).
for i, photo in ipairs( photos ) do
local photoName = photo:getFormattedMetadata('fileName')
   if photo:getRawMetadata( 'isInStackInFolder' ) then
   --Photo is in a stack
        local photoHeadOfStack = photo:getRawMetadata('topOfStackInFolderContainingPhoto')
        local stackPos = photo:getRawMetadata( 'stackPositionInFolder' ) -- get the position in the stack
        local photoHeadName = photoHeadOfStack:getFormattedMetadata('fileName')
        app:logVerbose("Photo nb ^1, name ^2 is in a stack with the position ^3", i, photoName, stackPos)
        if stackPos == 1 then
        -- photo is master of the stack
             stackTop[#stackTop+1]=photo
             app:logVerbose("Photo ^1 is top of the stack ^2", photoName, #stackTop)
             -- check if couple if correct
        elseif photos.photoHeadOfStack then
             app:logVerbose("Photo ^1 is in a stack, but not on top. Top of the stack already selected", photoName)
        else
             stackTop[#stackTop+1]=photoHeadOfStack
             app:logVerbose("Photo ^1 is in a stack, but not on top. Top of the stack ^2 - ^3 ", photoName, #stackTop, photoHeadName)
        end
end
end
In the if structure in the middle checking the Position in the stack, if the Position is not 1, I would like to check if the photo heading the stack ('photoHeadOfStack') is part of 'photos'. I tried 'elseif photos.photoHeadOfStack then' and 'elseif photos[photoHeadOfStack] then' but it doesn't work ->this elseif is never true even if 'photoHeadOfStack' is part of 'photos'.
Is there anyway to have this check done without checking "manually" photos ?(via for example a for Loop)
I'm sure that Lua proposes this, but I don't know how...
I thank you for your Support!

    --[[ This code creates "stackTops", an array of LrPhotos that are the
    tops of all the stacks containing photos in the array
    "photos". ]]
stackTopSet = {}
for _, photo in ipairs (photos) do
    local stackTop = photo:getRawMetadata ("topOfStackInFolderContainingPhoto")
    if stackTop ~= nil then stackTopSet [stackTop] = true end
    end
stackTops = {}
for photo, _ in pairs (stackTopSet) do table.insert (stackTops, photo) end

Beginner Question: SA520 Admin access through WAN port

Dear all,
I've a beginner question regarding my brand new SA520: How can I configure the box so that I'm able to access the admin GUI not only through the LAN ports but also from the WAN ports?
I tried already to allow inbound traffic to the firewall's internal IP address (not sure if done right, so) and granted the admin user access profile from WAN and LAN: I can access the box from the LAN but not from the WAN. Any ideas?
Thanks,
Eric
PS: Yupp, I know that it's not a good idea to expose a FW admin GUI to the WAN - but this is only a lab environment

Go to Administration -> Users.
click on the 'Edit User Policies' 'Login' button. It's there you can enable WAN access.

Beginner question - using pre for flexibility in text?

Hi,
Apologies for the beginner question, but I am struggling to work out whether it is more sensible to use <pre> in all my texts, as it seems more flexible.
It seems that when I use <p> - paragraph - I can't use multiple space bars to align certain bits of text, but more disruptively I have gaps between text when I press Enter (I guess this defines the paragraph, but isn't always wanted).
Well, basically, <pre> seems more flexible, but it behaves strangely sometimes. What do other people use?
Many thanks!
Ivan Reshetilov
http://www.ivanreshetilov.co.uk

Hi Ireshe, just a beginner like you. Have never heard of <pre> tags, use <p> tags. If you hit SHIFT enter after a sentence this puts in a <br> tag or line break which basically leaves a blank line between text.
If you add     &nsbp;    or lots of them between words this gives you an extra space between letters. How all your paragraphs sit on the page is defined by CSS. E.g.
p {
     margin:0;
     padding: 5px 0 0 10px;}
This would place all text within <p> tags on your page, with a 5px gap at the top, no space to the right or bottom and 10px space to the left. Hope this helps, good luck!

Beginner question: Configure Tomcat for JAAS?

Hi,
This is a beginner question :-(. I'm trying to get JAAS to work on my Tomcat (6.0.12) installation. I used code from a Javaworld article (http://www.javaworld.com/javaworld/jw-09-2002/jw-0913-jaas.html)
Of course I had to configure my Tomcat to work together with JAAS. The document I used is: http://tomcat.apache.org/tomcat-6.0-doc/printer/realm-howto.html
According to the Tomcat doc I have to do the following steps before I can use JAAS to authenticate a user:
1. Develop your code. Place the compiled classes in Tomcat's classpath
2. Setup a login.config file for Java, and tell Tomcat where to find it (set JAVA_OPTS)
3. Configure the JAASRealm in your server.xml
1 Develop code: I use the following classes:
PassiveCallbackHandler.java
RdbmsCredential.java
RdbmsLoginModule.java
RdbmsPrincipal.java
These classes I put in the package rdbmsjaas.
In the %CATALINA_HOME%/webapps/Javaworld_Jaas/WEB-INF/lib directory I created the rdbmsjaas.jar file.
The jsp is called jaas.jsp, and is stored in %CATALINA_HOME%/webapps/Javaworld_Jaas
2. Setup login.config
In %CATALINA_HOME%\conf I saved the file Javaworld_all_that_Jaas.config, containing:
Example {
   RdbmsLoginModule required
   debug="true"
   url="jdbc:mysql://localhost/jaasdb?user=javauser&password=javadude"
   driver="com.mysql.jdbc.Driver";
};I created an XP Environment Variable JAVA_OPTS with the value <-DJAVA_OPTS=-Djava.security.auth.login.config==C:/Program Files/Apache Software Foundation/Tomcat 6.0/conf/JavaWorld_All_That_Jaas.config> (excluding < and >)
I used the fully qualified address, instead of $CATALINA_HOME/conf/JavaWorld_All_That_Jaas.config. I think XP balks when it sees $CATALINA_HOME).
3 Configure JAASRealm in server.xml
In %CATALINA_HOME%\conf\ I changed web.xml. I added the following lines:
      <Realm className="org.apache.catalina.realm.JAASRealm"
             appName="jaas"
             userClassName="rdbmsjaas.RdbmsPrincipal"
             debug="99"
       />If I run the jsp from http://localhost:8080/JavaWorld_Jaas/jaas.jsp, I can enter my username/password, but when I click the Submit button, I get:
Caught Exception: java.lang.SecurityException: Unable to locate a login configurationWhere did my configuration go wrong?
Abel

You will need a JSP/servlet engine such as Tomcat - Apache alone won't do it.
I haven't seen any tutorials on set-up but the Tomcat documentation includes info on how to link to Apache. There are also books you can buy - check out the online book stores such as Amazon.
There's also a lot of info on this forum.

Beginner question: creating my own virtual instruments from samples

Hi, I have a beginner question. I'd like to make a click-track, but I want to use my own sounds, either recorded or from the internet. Can I do this with Logic Express 7, or do I need Logic Pro 7 and the EXS24?
Thanks,
Ryan

I think you can do it, but it might be a pain.
You could import a sample of a single click and just paste it into every beat on the Arrange Page.
Other than that, you might need the sampler included with Logic Pro
