• Why color Temp does not use theory standard blackbody in lightroom?

  Hi all, I would like to ask a question. Why the temperature in Lightroom does not use theory standard blue witch bsigns black body for higher values and the red ones for lower values on the kelvin color temperature scale?

  I'm not a novice and a motion graphic designer and 3D generalist and I do not understand why the Lightrooms does not use the normal scale. You go to a 3D ap and if you are familiar with lightroom you will have some problems whit lighthning because in all the 3d points and from what I've seen other counters aps use the kelvin color temperature values, higher values are asigned to blue spectrum. For example, with a bulb (D65) of natural light has a value of 2700 Kelvin is the red color red but in lightroom is on the opposite side and 2700 you have a tint of blue. I personally find very annoing this approach and I would like to ask Adobe if they could put an option to change the color temperature scale Kelvin standard.

  Thank you

  http://en.Wikipedia.org/wiki/Color_temperature

  Cursors do not set the light black body temperature, but compensation requested the image to compensate for the temperature of the black body of light.  This is going the other way.

  If a picture is taken in tungsten (light that is yellow-ish), we always want to look white 'white' when view us on a screen (as our eyes compensate for the color temperature of the ambient lighting).  To adjust to the lighting low temp black body (i.e. yellow-ish), so we want to make the image more blue, so it does not yellow.  Until the lower part of the blackbody temp lighting (i.e. more yellow enlightenment), the more blue the compensation that we must apply.

• Why xmlindex is not used in the slow queries on xml binary table eval?

  I run a slow simple query on Oracle 11.2.0.1 database server that does not use a xmlindex. Instead, a full table scan against the table eval binary xml occurs. This is the query:
  

   select -- /*+ NO_XMLINDEX_REWRITE no_parallel(eval)*/
        defid from eval,
        XMLTable(XMLNAMESPACES(DEFAULT 'http://www.cigna.com/acme/domains/eval/2010/03',
        'http://www.cigna.com/acme/domains/derived/fact/2010/03' AS "ns7"),
        '$doc/eval/derivedFacts/ns7:derivedFact' passing eval.object_value as "doc" columns defid varchar2(100) path 'ns7:defId'
         ) eval_xml
  where eval_xml.defid in ('59543','55208'); 

  The predicate is not selective at all - the number of rows returned is the same as the number of rows in table (325 550 in the eval table xml documents). When different values are used, which brings the number of lines down to ~ 33%, the xmlindex still is not used - as is expected in a purely relational XML environment.
  
  My question is why would'nt the xmlindex be used somehow full scan compared to a sweep of full table that cross the xml for each record in paper table eval?
  FFS suspicion would apply to a field of type xmlindex index?

  Oracle XML DB 11g Release 2 Developer's Guide is not much help...
  
  Any help is appreciated.

  XMLIndex definition is not correct, for the following reasons:

  In the COLUMNS clause, the path expression is compared to the context from the main event of XQuery item (HERE "/ eval").
  If you use an initial slash as you did, this indicates that the context item is an element of "derivedFacts" (which is not correct since it is an "eval" element).
  Therefore, the path points to no existing node:

  derivedFact XMLTYPE path ''/derivedFacts/ns7:derivedFact'' virtual
  

  There is a mismatch between the statements of prefix ns7, probably a typing mistake?

  ''http://www.cigna.com/acme/domains/derived/fact/2010/03'' AS "ns7"
  ...
  ''http://www.cigna.com/acme/domains/derived/FACT/2010/03'' AS "ns7"
  

  What "eval_xml" is referring to here?

  passing eval_xml.derivedFact
  

  The path to "defId" don't go too:

  defId VARCHAR2(100) path ''/derivedFacts/ns7:derivedFact/ns7:defId''
  

  Try this one, it should help you to:

  CREATE INDEX "EVAL_XMLINDEX_IX" ON "EVAL" (OBJECT_VALUE)
  INDEXTYPE IS "XDB"."XMLINDEX" PARAMETERS (
  'XMLTable eval_idx_tab_I
    XMLNamespaces(''http://www.cigna.com/acme/domains/derived/fact/2010/03'' AS "ns7",

  Hello, brichter!

  Thank you for joining the communities Support from Apple! Looks like you're wanting to rotate the Zoom mode on your iPhone screen. It is a big question. Read this post here that talks about how make a use display Zoom on your iPhone 6 and later versions. As you can see here:

  With the Zoomed see on an iPhone 6 or 6 s, iPhone Home screen does not rotate landscapemode.

  I have NOT used and not STRUCTURED XML, but a STRUCTURED index rather XML index...

  • Index unstructured XML when introduced in 11.1 and use an ARRAY of path. Unstructured XML indexes are mainly used for research "blurred".
  • Structured XML indexes where introduced in 11.2 and make use of one or more TABLES of CONTENTS that contain, must contain content of the structured parts in the XML document

  So I have not used

  CREATE INDEX IX_FXXX_AAA_BBB_FB_FB
  ON FXXX_AAA_BBB_FB (XMLRECORD)
  INDEXTYPE IS XDB.XMLINDEX
  PARAMETERS ('  PATH TABLE IX_PATH_TABLE
                  PATHS (  INCLUDE ( /row/c2 /row/c81 ))'
              );
  

  but instead I used a XML structured, based on the function XMLTABLE index

  CREATE INDEX IX_FXXX_AAA_BBB_FB_FB
    ON FXXX_AAA_BBB_FB (XMLRECORD)
  INDEXTYPE IS XDB.XMLINDEX
    PARAMETERS (q'# GROUP SXI_GROUP
                    XMLTABLE SXI_CONTENT_TABLE
                    '/row'
                    COLUMNS
                      C2  VARCHAR2(100)     PATH 'c2'
                    , C81 VARCHAR2(100)     PATH 'c81'
                  #');
  

  On those, I also created EXTRA build secondary indexes on the columns of the TABLE CONTENT with the name 'SXI_CONTENT_TABLE '.

  create index SEC_FXXX_C2_FB on SXI_CONTENT_TABLE(C2);
  create index SEC_FXXX_C81_FB on SXI_CONTENT_TABLE(C81);
  create unique index SEC_FXXX_RIDC2C81_FB on SXI_CONTENT_TABLE(RID, C2, C81);

• Structured XMLIndex not used by the query

  Hello

  We try to use XMLIndexes structured for a query. But they are not used. A sample of similar work is as follows:

  
  -Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production

  Example of XML data on the XMLTYPE column is:

  <?xml version="1.0" encoding="UTF-8" standalone='yes'?>

  - But the query above does not use the XMLINDEX STRUCTURE and instead turns to FTS INT_PART_TABLE.  Please help here.

  Is it the wrong way I created structured Index.

  (I tried a few other ways where I got-> ORA-19279: XPTY0004 - dynamic XQuery type mismatch: expected - singleton sequence got several sequence element).

  S ' Please NOTE that I used two "VIRTUAL" during the creation of the Index as otherwise I was getting the error:
  ORA-29958: fatal error occurred in the execution of routine ODCIINDEXCREATE
  ORA-30984: the XMLType column must be declared as virtual

  Please suggest. Thank you.

• I tried to download CS4, but it will not download.  Says that I need to improve, but cannot do so unless I am owner CS1, 2 or 3.  Why don't I just use what I bought.

  I initially bought CS4 in 2009 but wiped out long and sold the computer that was on.  I tried to download CS4 on my current computer but he said setting up the version I have is the one that needs to be upgraded and to be eligible for the upgrade, that I need to have bought an eligible product (which I don't own) as CS 1, 2 or 3.  I can not just use the CS4 I bought initially?  Why should I buy something else to use what I bought?

  Hi Gina Kugler,.

  Make sure you download the suite CS4 or product that exactly matches what you had initially: Download Adobe Creative Suite 4 products. Serial numbers are for specific products.

  If you have done this, and you still receive the prompt for an eligible item, this means that your serial number CS4 is a upgrade product: error: "this serial number is not for a product calling it" | Adobe Creative Suite. If this is an upgrade and you installed before, it must have been an earlier qualifying version of CS on your old computer. Because none of the previous versions are installed on your new computer, however, a CS4 update will ask a qualifying serial number.

  If you are unsure if you already have a previous version of Creative Suite, you can check in your products & plans to sign in French - Adobe ID . You can also contact customer service. Click on the blue "Still need help?" button, and then select chat. Cat representatives are unable to provide troubleshooting techniques for older products such as CS4, but they can search for serial numbers, including under the alternate emails or phone numbers.

  Let us know if that helps.

  Best,

  Del

• Why don't we not constantly update?

  We run a business on the internet very nice and let 5 computers work hard however we continue to be updated almost every week. It became a chore to use Firefox. When we started to use Firefox, years ago, that we could get an update 2 times a year, now it seems that 2 times a month. Please let us know why and if there is something we can do to change that. Update and unnecessary changes is very costly for our business and if she continues to make us perhaps change browsers. We love Firefox but updates must stop be so frequent. We do not have the time to update or do we not want any computer update unless someone watching him. We don't want automated updates. Update was the worst when you have made all of the unnecessary changes. It took me all day to all 5 computers to look alike so everyone can use anywhere they work. Please consider yourself a browser at the top of the page and not a fly by night. It is a professional company, so please act like him, walk like and this u-turn. I wonder if someone from Microsoft has begun to help you?

  New versions are released every 6 weeks for over 3 years now. There are several versions of "chemspill" both Firefox 32 and 33, since early September, to address the issues of security or because of the accident of bugs to a small part of the base installation.

• Why VMware Player is not using AMD - V?

  I have the latest version of VMware Player (3.1.2 build-301548) and an AMD Athlon 64 X 2 Dual-Core Windsor (AMD - V compatible and active) and Windows 7 Ultimate 64-bit but VMware repeat myself that "this host does not support all hardware virtualization".

  Someone knows why?

  Thank you very much.

  Aedan says:

  So, my CPU is defective?

  Essentially.  There are some situations in which the first generation of AMD - V hardware is insufficient to completely accurate virtualization.

  It of bad, but can't I "force" VMware to use AMD - V still?

  You can not force VMware to use AMD - V.  Support for AMD - V on these chips fell.  You can use VMware Player 2.0, if you want to support AMD - V for your CPU, but I don't know why you would want it.  Without material assistance to MMU virtualization, AMD - V does not generally offer benefits of performance over binary translation.  See article ASPLOS for some comparisons.

• Why "scratch disks" are not used in PS CC 2014

  When you change a major project which include several layers of images and smart objects, I often use up all available RAM. Just as 14FR is reached, I get a RAM error output and can not save (usually the smart update objects, it is what comes in the error)

  OK, I'm out of RAM. But I have set up a 400GO disk drive scratching in the preferences. Why is that not accessed in order to complete the operation?

  AdbeOper wrote:

  a Windows message comes up saying I need to close a program due to low memory.

  I see you have just 5 GB free on drive C. Seems to me the obvious and immediate problem. Especially since you have Photoshop for the allocation of memory all the way upward (which you should never).

  Remember that the OS does its own pagination — not only for other applications, but for a lot of process system running continuously in the background.

• Why don't will not open Photoshop CS2 after installation.

  I got Creative Suite Premium installed on my laptop for years and not had any problems.  I installed it on my home office and activation has been accepted.  Other programs of the Suite work but Photoshop will only as far as the blue window and the hourglass just sits there.  I work with XP Pro and when I open the Photoshop Task Manager is presented as does not.  I tried to repair it with the installation disk and I tried to uninstall/reinstall twice but nothing seems to help.

  As I put the Suite on my laptop, the installation discs were on my book shelf.  What could possibly prevent opening Photoshop?

  Many thanks in advance,

  Jim Lynn

  What is shown in the blue like loading window when the thing freezes?

  Have you tried to reset your preferences, as described in the FAQ.

  http://forums.Adobe.com/thread/375776?TSTART=0

  You must physically delete (or rename) the preference files or, if you use the Alt, Ctrl, and shift, don't forget you get a confirmation dialog box.

  This resets all settings in Photoshop default.   A complete uninstall/reinstall will not affect preferences and a corrupted file may be the cause of the problem.

• Why don't blgs not load correctly the first time

  Why are there several "refreshes" to properly load the pages for blogs?

  DNS prefetching

  Firefox tries to speed up loading new websites using DNS Prefetching, which can cause errors in loading page with some configurations of the system. To disable DNS prefetching:

     In the Location bar, type about:config and press Enter.
         The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.
     Right-click in the list of preferences, select New, and then select Boolean.
     In the Enter the preference name window, enter network.dns.disablePrefetch and click OK.
     Select true when prompted to set the value and click OK.
  

  This work fine for me. blank page nor any stop refreshing just to get to a site.

• Why BrowserField demo does not use BrowserField?

  I had some problems getting the BrowserField object to display all images on a page. When you search the formus, it was suggested to use the BrowserFieldDemo included in JDE for example. I tried and it works, but the back button does not work and you can not click on one of the links. Then I discovered that it does not actually use a BrowserField object as in

  net.rim.device.api.browser.field2.BrowserField
  

  Does anyone know how to make the browserField to work... WITH a functional back button and no image broken?

  I'd appreciate all point in the right direction.

  In fact, I realized that BrowserField demo uses OS 4.0 components while the BrowserField object is only OS 5.

• Why some OCD is not used to generate the output?

  I use RoboHelp 11 on Windows 8.

  I use a print single source layout that uses a table of specific contents. However, when the output is generated the same set of topics are included, none of which are in the selected table of contents. I'm mystefied, and in the hope that there is something that I forgot to select Properties.

  Here's what I use.

  

  And here is the created files:

  

  The TOC file is empty. The 'Expédition' file contains the contents of a subject who is not in the table of contents.

  Help?

  AHA. Found the answer in the article by Peter Grainge (printing problems). Thank you, Peter!
