Does make any sense to use Adobe RGB to process a photo taken in sRGB?

On the one hand, it seems that color for any photo post-processing would be limited to information of color captured by the sensor.  You cannot work with information that isn't here.  For example, if the camera were to sRGB, sRGB information don't that would capture all the sensor.  Post processing in a larger color space like Adobe RGB, would be foolish.  On the other hand, I suppose it is possible that PS, during any process of development of color, could present me with ARGB options (i.e., options a wider color space) and map of smaller space (sRGB) to the largest (ARGB).

As far as I know, most DSLRs offer sRGB or ARGB option.  However, I know there are those who value their color space ProPhoto in PS; so, there may be a post processing value in a color space that is larger than the space used by the camera to capture color information.   In case it is not obvious, I'm confused.  Any help would be appreciated.  Thank you.

If you capture images JPEG in sRGB then files are limited to smaller color space and cannot be extended to a larger range such as Adobe 1998 or ProPhoto color space.  If your RAW capture files then it's not what your profile settings of cameras are because the Raw files are just text information of your sensor which has not been made to the pixels even serious.  It's an essential difference.  If you open a RAW file in ACR you can render pixels in any color space.

  • It will make any sense to create a view, materialized on the top one cube MOLAP?

    Hello
    We have developed a few MOLAP cubes for our environment considered.
    Now, we plan to create materialized with rewrite motion activated to speed up performance?
    Is this a good approach? It will make any sense? I want to say I get a performance improvement if I create MV at the top of a MOLAP cube?

    Thank you and best regards,
    Douglas

    Adding a MV rewrite does not alter the raw performance of a cube. The only reason to add - it is if you want to write your SQL queries against relational base tables and the database have rewrite your queries on the cube. If you are able to query the views of cube directly, so there is no particular advantage to a rewrite MV.

    Adding a refresh only MV has benefits even if your queries using views of cube. A refresh only MV following the lapse of the cube and allows you to run updates of 'fast', which can be useful if you are only changing a handful of lines in your fact table.

  • Recently no matter what I do, Firefox does not allow me to use Adobe Reader rather than his own

    I used to be able to display pdf documents using Adobe Reader instead of Firefox built in. I tried everything that you suggest and what Adobe suggest. I uninstalled and reinstalled Firefox. I uninstalled and reinstalled Adobe Reader (11.0.09). I went to the options of Mozilla, but when I try to change the settings of Document Portable, I don't get the option "Use Adobe Acrobat (in Firefox)". I get the Adobe forms but not for PDF documents. If I change to use Adobe Reader, it downloads and then open drive which is not I want. I want to use the plugin installed (I go to modules and it is installed and "always enable").

    Help? This only started happening in the last month or two. I use the latest version of Firefox (33.0.2), Windows 7 (updated with all the updates, etc.).

    I did a Reset Firefox. Then reactivated the plugins. Now he works with the Adobe Acrobat plugin, even if Firefox think (at least according to the Options-> Applications) that he uses the Foxit plugin. It does not give me the option to select the Macromedia software. But which loads when I access a PDF file!

    As long as there is the work, I don't care on this issue.

    Before that I started posting here, I already tried to uninstall and reinstall Firefox, uninstall and reinstall Adobe Reader, by removing the file pluginreg.dat, etc. and everything that I could find on the Mozilla site, the Adobe site and the rest of the web.

    Thank you for all your help.

  • Adobe RGB 1998 Workspace vs Image with embedded sRGB profile

    I worked through countless published on the Web about various aspects of the profile settings of colors from all different angles. Obviously a difficult topic depending on how much you must understand.  For now, I have a question of several party who I would appreciate any feedback on of those in the know.  I'll try to summarize it briefly - it is simply in the default RGB color space setting in CS6 against opening an image that has a different embedded color profile.

    Question

    (1) is it interesting 'potential' to work in color space Adobe RGB 1998 if I open an image with an embedded sRGB profile and "preserve embedded profile?  I realize that any potential benefit could depend on the range of colors in the image itself - that is, where an image with color dull or limited range could not affected by any color profile or workspace is applicable.

    (2) if my color default RGB in CS6 space is Adobe RGB 1998 and I open an image with an embedded sRGB profile, can I convert to Adobe RGB to take advantage of the widest range when working with the image.

    (3) if I don't need to convert an Adobe RGB sRGB image to enjoy the widest range when changes but must register the image with an sRGB profile for purposes of production (out of print or Web presentation service):

    3.1 should I make a copy of the image final and Convert to sRGB or I can just save as Jpeg and select sRGB for the profile to be integrated?

    3.2 irrespective of how I save the final image with an sRGB profile, I would lose some advantage I might have seen while working in the Adobe RGB workspace?

    I am not questioning if there is a good reason to work in sRGB vs. Adobe RGB (or ProPhoto) or under what circumstances it can matter - just trying to figure out a couple of mechanics I would work in Adobe RGB, but have a lot of things (slide previous scans etc.) than sRGB or some other built-in profile.

    Also not to query the best camera settings as I am completely convinced the only way to go is to capture in RAW if the goal is a flexibility to work with the picture (I'm still shooting Fujifilm Provia 100F in my Nikon F6 but eventually will go with a good FX digital SLR when I can rotate - point being that all of the images that I work with is roughly slides scanned on my Nikon Super) COOLSCAN 5000 ED Scanner).

    I understand that it is a topical subject (sRGB vs RGB etc.) and not trying to stimulate a wide debate on the issues.

    Thanks for any thoughts you may have on this topic.

    Jerry Keenehan

    p.s. Here is a comparison of an image of the test case of 14 CS6 Adobe class-in-a-book.  "Rev00" on the left is the original image to sRGB included with the tutorial; "Rev01' on the right is the picture where I have first of all"affected"the Adobe RGB profile, and then (through ignorance, maybe, converted - profile Adobe RGB). I did that because I noticed that I simply convert RGB perceptual colors remain the same, so that if I have 'assign' RGB profile, I certainly get a slight pop at this image - may not be noticeable in this screenshot, but I can definitely see an improvement that I love watching them side by side on my Apple LED Cinema display 27 ".

    Screen Shot 2016-05-21 at 3.43.30 PM.png

    That is right. If the file has embedded sRGB, Adobe RGB workspace is unnecessary and irrelevant. He never comes into play.

    You can, however, convert the file in Adobe RGB if you plan to make a big change on that, and you think you might need the extra margin of a larger color space.

    If you assign a profile (for an untagged document), there is not need to convert to the same.

  • PS 7 Why does not Adobe RGB files?

    I have an Olympus E-620 DSLR. When I put the color space in the camera into sRGB, after downloading the images, when I click to open in Photoshop 7, the images are correctly identified as sRGB files. When I put in the camera to Adobe RGB color space, Photoshop does not recognize the format. Please see the picture below.

    Question 1: Why does Photoshop not recognize Adobe RGB files?

    Question 2: What can I do to make Photoshop recognizes the Adobe RGB files?

    Question 3: If I assign the Adobe RGB profile in Photoshop to Adobe RGB file unrecognized, that even make any sense? Are 'additional data' Adobe RGB offers compared to sRB there again even if the profile is not recognized in the first place?

    I am very grateful for all the comments and tips!

    http://i30.tinypic.com/zv8qk8.jpg

    Assuming these are JPEG images, JPEG format use integrated EXIF metadata to indicate that the files are sRGB. In the EXIF specification, there are only two possible in the metadata, either sRGB or unspecified flags. He doesn't are not of type ICC profiles full files, just tags. When a camera is set to Adobe RGB, it cannot set the Adobe RGB color space in the EXIF metadata. The camera makers have circumvented this limitation is often include underscore in the beginning of the name such as _IMG12345, JPG. Photoshop 7, which is very old, does not understand the importance of underscore in regards to an indication of the different RGB color space. Currently versions do... might be time for an update eh?

    And, as Chris said, you need to avoid warning of profile and assign Adobe RGB images.

  • Adobe lightroom does not update when I use the application manager to download upgrades.

    I have problems with adobe lightroom.  It is not updated when I use the application manager to download the new updates.  I tried to uninstall the application and re-download it, however the application manager will not allow that to happen because it shows that it is already installed and up to date. I think that the problem may have started when I installed lightroom using a link which you offered when creative cloud first started offering of lightroom.  This version of the program does not appear to work with the application manager.  Please let me know what I should do to fix the problem.

  • Adobe Premiere Elements 10. Does make sense to upgrade my 32 GB memory?

    I have the following Setup (purchased in September 2011).

    • ASUS P8Z68 DELUXE, chipset Z68
    • Intel Core i7 2600 K 3.4 Ghz, 8 MB
    • Kingston
    • M4 128 GB crucial SSD
    • ASUS GeForce Ti DirectCU TOP 1 GB 2xDVI II GTX560
    • WD 2 TB sata 600 (black edition).
    • Windows 7 prof 64 bit.
    • Adobe Premiere Elements 10 + Photoshop Elements 10

    On the 128 GB SSD, I installed Windows 7, office 2010, Adobe software, and the SSD is used to swap/temp-drive for Adobe elements and Windows 7.

    The second WD SATA 600 black 2 TB drive is used for all my equipment photo and video.

    When searching on the internet and on this forum, I understand that until the first elements Adobe 9 unused RAM memory beyond 3 GB because of the 32-bit adobe core of the series of elements.

    Can you and first Elements 10 (or higher) will use memory beyond 3 GB?

    When I install 32 (4 x 8 GB) GB of DRAM memory, the recommended windows pagefile will be around (2 x 32 =) 64 GB. With windows 7 and some software installed there are not a lot of space on the SSD to the first elements temp adobe reader. I probably set the temp on the WD 2 to 600 sata drive because there is more free space left.

    I don't know if it makes sense to upgrade my memory.

    1 does make sense to upgrade my 32 GB memory? And it will probably increase the rendering speed of the first 10 elements (or a version later first)?

    2 it is sensible to upgrade my memory up to 16 GB (4 x 4 GB)?

    3 the 32 GB memory-implementation to date costs about 300 euro/dollar. Is there a better way to improve the rendering speed (I'm not comfortable with overclocking the system)?

    Hope you can help me with this question.

    Thank you!

    You have a lot more power to edit AVCHD and other high-def video.

    You certainly won't hurt anything by adding more RAM - but you won't see better performance with first Elements 10 from 8-16 GB of RAM.

    If so, I'll be able to continue to use this intro for these purposes, if I decide to leave the subscription?

    I looked this info on the EULA for Adobe fonts and the font itself, but the information was not conclusive.

    Thank you!

    Licensing - in particular for fonts - is always a big pain - and even if you have a lawyer paid handsomely on the case, it is always a challenge to navigate in all licenses of the difference and the different situations.

    In reality, the chances of trouble to use a font Adobe provides as part of the suite Creative Cloud is little or none - even if it's TECHNICALLY in a kind of fine print.

    However if you are doing a project where you must provide tangible evidence that everything is legally more High Council (which you have to do a lot of time for projects that are funded for example the Government), then things can become difficult.

    In the case of Myriad Pro - even though the creative cloud agreement specifically lists the fonts in the list of the restricted fonts - you can always register Myriad Pro through Adobe's Typekit service (see: Myriad Pro |) Typekit) so that circumvents this problem.

    My advice - if you need evidence that the fonts of your use of any good - then I would contact Adobe directly, in order to have their response in writing. See: https://helpx.adobe.com/contact.html

    If you are just doing a personal project, and you put the work on YouTube (even if you get advertising revenue as part of the YouTube partner program), and then the case to get into any kind of trouble because of policies is VERY thin - but if you want to play it is really safe, it is best to do your research , and make sure you have something in writing say that everything is perfect.

    If in doubt - talk to a lawyer, because they will be able to do a risk assessment appropriate - even if it is somewhat a grey area.

    We had similar issues trying to license of Adobe Stock content - a few clauses in the agreement that is very unfortunate entertainment lawyers.

    I downloaded a copy of XP Pro SP3 file you need on my SkyDrive (everyone has a SkyDrive for file sharing).

    You can download it and when you do, place a copy of the file in these two folders (assuming that Windows is installed on your C drive):

    c:\Windows\System32
    c:\Windows\System32\dllcache (this is where XP keeps backups of important files).

    Here is the link to my SkyDrive and you can get the file you need here:

    When you see the files available for download, you can not see the file extension (.exe, .dll, .cpl, .sys, .zip, etc.), but when download you them they will have the right extension.

    When you download the file (especially if you use Internet Explorer), when you get a chance to save the file, your browser is unable to save the file with an extension (by example, .exe, .dll, .cpl, .sys, .zip, etc) then you will need to manually add the extension appropriate to the file when you download the file before you save it.

    You can download the file without the extension, and then rename the file to add the appropriate extension.  You do not want to use a file called winhttp when the name of the file should really be called winhttp.dll (if the downloaded file has no extension, you will need to change the name of the file to add the appropriate extension to make it work.

    You then put the downloaded files in the correct folders on your system.

    Hello experts,

    I use Adobe Forms in SAP.

    My question is, is there a any restriction for additem keyword in JavaScript?

    I mean, even if I use the keyword additem to add the name and value of a drop-down list, it adds up to 10000 files only.

    Please sugest

    A drop-down list is the bad INTERFACE design where an element can contain more than 100 entries. It is very good in tests, but absolutely unacceptable if the form must be used by a person busy doing their work. The choice of Acrobat forms are limited, but consider a list box. Despite this, there may be limits imposed by the system or the implementation.

    Better would be

    (a) stop filling after awhile the list and add an entry saying several elements not shown, running report or use better filter

    (b) be available for all filtering of course lists

Note that none of the other newspaper, the files are updated either (Plugin Loading.log, Database.txt Trace and Debug Database.txt). All these get updated when I run the desktop/start. It would appear that SG is not yet known.

    I uninstalled the SG and the PP and re-installed (all in the directories by default) and everything seemed to go OK but no change.

    I also added 2 political profile the NVIDIA Control Panel, just display a message when loading SpeedGrade.exe and another for a slightly different message when loading SpeedGradeCmd.exe. SG invoking the desktop/start causes the SpeedGrade.exe message to display.
