How do I properly use the HDR function in Photoshop CS4?

It appears that I must be doing something wrong when attempting to use the HDR capability in Photoshop CS4. I follow the tutorials. I go to File>Automate>Merge to HDR. Then I select the bracketed photos to merge. I have used RAW file combinations of "normal" with +1 and -1 exposures, and "normal" with +2 and -2 exposures. Inevitably the result comes out looking like the most overexposed shot...or even more washed out. Since CS4 normally works for me as intended, I feel that I must be doing something wrong with the HDR function. Can anyone offer any helpful suggestions? Thanks!

Don't feel bad. While I haven't seen just what you're describing, the Merge to HDR function seems, in my opinion, kind of a bust. I can't say I've seen any "magic" at all in the way it combines the exposures.
I've tried to use it several times and I just don't see results that make me feel it's worth using. I have in every case been able to make better images out of a single well-exposed raw file than with the Merge to HDR function and several bracketed exposures (even with CS5's Merge to HDR Pro).
If people offer suggestions here, I'll be trying them too.

Unable to change reference point location while using the Transform Functions in Photoshop Elements 6.0.

Which operating system are you using?
In photoshop elements 6, as far as i know, you can only change the Reference Point Location for transforms using the small grid in the left hand corner of the tool options bar with Transform enabled.

How to use the Table Function defined in package in OWB?

Hi,
I defined a table function in a package. I am trying to use that in owb using Table function operator. But I came to know that, owb R1 supports only standalone table functions.
Is there any other way to use the table function defined in a package. As like we create synonyms for functions, is there any other way to do this.
I tryed to create synonyms, it is created. But it is showing compilation error. Finally I found that, we can't create synonyms for functions which are defined in packages.
Any one can explain it, how to resolve this problem.
Thank you,
Regards
Gowtham Sen.

Hi Marcos,
Thank you for reply.
OWB R1 supports stand alone table functions. Here what I mean is, the table fucntion which is not inculded in any package is a stand alone table function.
for example say sample_tbl_fn is a table function. It is defined as a function.It is a stand alone function. We call this fucntion as "samp_tbl_fn()";
For exampe say sample_pkg is a package. say a function is defined in a package.
then we call that function as sample_pkg.functionname(); This is not a stand alone function.
I hope you understand it.
owb supports stand alone functions.
Here I would like to know, is there any other way to use the functions which are defined in package. While I am trying to use those functions (which are defined in package -- giving the name as packagename.functionname) it is throwing an error "Invalid object name."
Here I would like know, is there any other way to use the table functions which are defined in a package.
Thank you,

Thanks
Arnab

Hi Arnab,
The expression is checked only for the current MDM session.
If u login with the ABC language it will always show the ABC language no matter how many times u execute it.
Try connecting to the DM with the XYZ language.
It should go to the if part rather than else.
Hope it helps.

How to use the CMS functionality in Sun Portal Server 7.2

Hi All,
How to use the CMS functionality using the ccd.war(Portlet) which is available in the library as i could add it to my channel but not able to show the functionality as it is showing the error msg "You are currently not logged in. Please login." should I create userid and there respective roles inorder to use the CMS functionality.
Has any one used this as I could this in glass fish server.
Any Input is appreciated.
Thanks & regards
Srikanth

Have a look at the "*Roles*" section of the portal server 7.2 content management system guide
http://docs.sun.com/source/820-4275/index.html . You can also look at [project mirage|https://mirage.dev.java.net] for some screencasts
Alternatively,
1. ccd.war has 3 portlets in it:
(a) custom content definition portlet
(b) custom content portlet
(c) workflow portlet
2. Inorder to work with these portlets, user needs to be in anyone of the below roles:
(a)Consumer (b) Editor (c) Approver (d) Administrator (e) Submitter (f) Contributor (g) Publisher
3. By default ccd.war gets deployed using a default roles file (/var/opt/SUNWportal/tmp/ccd.roles.properties)
Note: In windows, you may not find this file
4. Access the portlets as a user in any of the role mentioned in the ccd.roles.properties
(OR)
you can use a new roles file which has mapping to your custom roles. For this , undeploy existing ccd.war and deploy again with a new roles.properties file
Hope this helps!

How to use the pps function from JCOP?

Hi
I'm trying to use the pps function from JCTerminal (JCOP API: [url http://www.cs.ru.nl/~woj/jcopapi/com/ibm/jc/JCTerminal.html#pps(int, int)]pps function ) to connect my client to a virtual card with a specific protocol (T=0).
But I always got the error: "Protocol and parameter selection not supported by this terminal!"
I've tried to make an ATR that support both protocol : [url http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc]3B 90 95 80 81 1F C7 DC.
I really don't know what value to put in the second parameter (baud rate), I've tried with 150000, which is in the range of the ATR but I'm not sure this is correct. And I could't find any example of it.
I'm also not sure where to put the pps command, the specification say directly after a reset, so I tried this implementation:
System.out.print("Start");
 readers = TerminalFactory.getDefault().terminals().list(State.CARD_PRESENT);
 //If no readers has a card it ends the process
 if(readers.isEmpty()){
 System.out.println("\nNo card in the reader...");
 return;
 System.out.println("\nReader Type: "+readers.get(0).toString());
 term = (PCSCJCTerminal)JCTerminal.getInstance("PCSC", readers.get(0).toString().substring(15));
 term.open();
 System.out.println("\nTerminal opened");
 //Getting the ATR
 atr = new ATR(term.waitForCard(2000));
 try {
 term.pps(JCTerminal.PROTOCOL_T0, (int)150000);
 } catch (Exception e) {
 e.printStackTrace();
 System.out.println("ATR: "+toHex(atr.getBytes()));
 //sending a data 11223344
 System.out.println("\nsending data: 11223344");
 byte[] responsesend = term.send(0,cmdsend,0,cmdsend.length);
 System.out.println("Response data is:" + toHex(responsesend));
 //close terminal
 term.close();
 System.out.println("\nTerminal closed");I've got this output on the console:
StartReader Type: PC/SC terminal Virtual CAD Reader 0
Terminal opened
ATR: 3b 90 95 90 00 81 1f c7 cc
sending data: 11223344
Protocol and parameter selection not supported by this terminal!
 at com.ibm.jc.JCTerminal.pps(Unknown Source)
 at com.test.essai.main(essai.java:46)

And If I take a look at the data exchanged with the card:

I'm using a virtual terminal (windows driver), and I don't see how I could turn off the Auto-pps. I've also tried with a real reader and a card and I have the same error.
-2
I've tried value in the range of the atr (based on this analysis: [url http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc]http://smartcard-atr.appspot.com/parse?ATR=3b909580811fc7dc ). But I don't know if only I value of baud-rate is possible in the range. Anyway I just would like to change the protocol, not the baud-rate.

I've already tried to call pps function before, after the first reset, or with another reset later and I always got the same thing.
 term = (PCSCJCTerminal)JCTerminal.getInstance("PCSC", readers.get(0).toString().substring(15));
 term.open();
 System.out.println("\nTerminal opened");
 //Getting the ATR
 atr = new ATR(term.waitForCard(2000));
 System.out.println("ATR: "+toHex(atr.getBytes()));
 jcard = new JCard(term,atr,0);
 jcard.reset();
 try {
 term.pps(JCTerminal.PROTOCOL_T0, (int)312500);
 } catch (Exception e) {

 }The same pps is always send after each reset...

How do I reorganize my photos on iPad 2? I need to move (not copy) photos from one album to another. When I use the copy function to another album, and then try to delete an image from the original album, the system wants to delete the photos from all albums. Please help.

You can't do it directly on the iPad - the new album functionality basically only allows you to copy photos into those new albums, you can't move them. The way that I think of it as working is that you are just creating pointers to the photos in those new albums, so if you then delete the original photo on the iPad you therefore automatically delete all the pointers to it.
If you want to re-organise your albums then you will need to do it on your computer and then sync those albums over to the iPad

How to use the set functions effectively in webi ,please let me know with detail

how to use the set functions effectively in webi ,please let me know with detail

Hi,
we use use set functions on heirarchies with aggregate functions mostly .
If you include member_set, Min returns the minimum value of the aggregated data for all members in the member set.
Member_set can include multiple sets separated by semicolons (;).
The list of member sets must be enclosed in {}.
If the member set expression does not specify a precise member or node, the hierarchy referenced must be present in the table, then the member set expression references the current member in the hierarchy in the table. If the hierarchy is not in the table, the function returns the message #MULTIVALUE.
Eg .
1)     Ancestor
=Sum([YTD] ; {Ancestor([Test Hierarchy];2)})
2)     IsLeaf
=[Test Hierarchy].IsLeaf
You can use this function when you want to show your Measure only at lower level .
3)     .Depth
=[Test Hierarchy].Depth
This is also function used with hierarchy to find Level of Members .

How to use the RV_EXPORT_CONTROL function (via 2LIS_11_VAITM extractor)

Hi guys,
I use the 2LIS_11_VAITM extractor to load R/3 data to BW.
On this extractor, there is an user exit which filled many fields.
I have to add the export control status of items, the value we can find in VA03 (Extras -> Export Licence -> Log -> Status green or Red).
I added a specific fields ZZEEXPCTRL (CHAR(1)) in my extraction structure as a field only know in Customer exit.
This flag will be empty if status is green or 'X' if status is red.
I'll try to use the RV_EXPORT_CONTROL function in my exit but it doesn't work.
When I execute in debug the 2LIS_11_VAITM extractor in RSA3, I can display the screen we have in VA03 (Extras -> Export Licence -> Log -> Status green or Red).
Maybe I use the bad parameters ?? But I tried many option, without result
Could you please help me and explain me how to use this function to have my result or if there is another way to do this ?
Thanks
Joris

Hi Namrata and Debjani,
Thank you for your suggestion. We are considering those options as well.
However, we are trying to aim for consistency between the "old" and the upgraded system. Therefore we are trying to find whether it is all possible to remove those two fields. If it is not possible at all to remove them, then we will do what you both suggested.
Best regards,
Fen

How to use the scan function on a 4215i all in one printer

How do I use the scan function on this printer with windows 8. I did the installation but the scan function does not seem to wwork
This question was solved.
View Solution.

Do you have the Officejet 4215 series All-in-One printer?
If so, then there is no full feature driver for the printer. The printer is installed using the Windows Update menu of the print drivers. For information about using the Windows Update driver click here.
Do you have this printer connected via USB? If so, then there are workaround methods to get the printer to scan, as the old software package is not available on Windows 8. In the document linked above, scroll down to the section on how to scan with the Update driver to find information on how to perform these types of scans. Hope this helps.
