Preservation of colours and space data going in and out of L.A.B for improving colors

There was a similar post 2 years ago, who not quite answered that very question.

I use a technique to improve the colors by converting in the LABORATORY and in application of the image in a mixture of overlay or softlight. My RGB images are all stored in the ProPhoto color space. They are all in RAW format (specifically about Nikon. (NEF). When I get in the LAB and then in RGB, it seems that ProPhoto are replaced by space color sRGB.

I then convert from sRGB to ProPhoto.

In this process, am I losing data of color as the range is pressed in sRGB which is not returned after going back to ProPhoto?

Hey Stan,

My first instinct is to ask how you go from lab to RGB.

Your settings Color PS maybe sRGB as the default value.  If you simply select mode / RGB, it will convert your lab color space sRGB profile. Certainly not what you're looking for.

You have two options, if this is the case.  You can open your color settings window by choosing the Edit menu.  Stand ProPhoto in your RGB setting by default if that's what you prefer to use most of the time.  You can save multiple custom configurations and choose them when they agree to the task at hand.

In addition, instead of select mode / RGB, you can choose "convert to profile" in the main menu to modify and configure your conversion it.  I usually use prefer to use this approach, since I can experiment with different settings.  It also ensures that I am converting my planned profile.

  • Artifacts when zoomed in and out

    Hello

    I have a new MBP for a few days. I can not complain. Great machine to work with design/photography. However, I think the experience of this kind of problem, I'm not able to solve so far.

    When you zoom in and out, I get these blocks of solid color. Sometimes, it is white and it is sometimes black.

    I have Intel Iris Pro graphics.

    Here is a link to see what it looks like: Microsoft OneDrive - access to files anywhere. Create docs with Office free online.

    Does anyone know how to fix it or will there be an update to fix it?

    I'm lucky I've got Photoshop on a PC, but also a Mac and the problem is not present on the PC. I really like MACs, but I think the Achilles heel is not being able to easily add third-party hardware. I think a third graphics card might just solve the problem of the mysterious black squares but Apple likes to keep manufacturing in the House. Also, it does not help that Yosemite is such a new OS.

    Have you tried pressing cmd 3 followed by cmd 2 when this happens because some people report it clears. All you do is put in the Red layer and RGB so you don't make any changes to the image.

  • 2d24DX HP 2000: screen goes in and out

    I have a HP 2000 2d24DX (Energy Star) last week the screen went black.  As I really saw what I could just came out the homepage.  After some research, it seemed that the inverter - to discover this laptop isn't an inverter and needed to replace the entire screen.   Ordered a new screen and replaced it. All seemed well, had a good display and a web cam worked.  Last night when I started towards the top of the screen came, and then I moved, he's out. If I picked up and it sitting on my knees down the screen would flicker on just a second and go back black.  I thought that perhaps I did not well related things, so today I took everything back out and made sure, it has been connected well.  Turned on and the screen came great.  The as soon as I moved the laptop, the screen disappeared again.  I can move to the screen and it signal inside and out.  At one point I got back in and sitting on the left.  The screen stayed for a few minutes, then he came out again without any movement.  Help, please.

    @lrshotton ,

    Hello and thanks for the display on the HP support forums.  What you have going on is a problem with the connecting cable to the display.  There is a short in it or who has never replaced the screen did not leave enough room for the cable travel when the screen moves.

    It may be that the connector was not well connected.

  • How to access the Non-space data of the object using the API of the HTML5

    Using the Oracle cards HTML5 API, is it possible to access the data an excerpt when generating a map?

    For example, my database has a table named ITEMS:

    Table: ELEMENTS

    COL_A

    COL_B

    COL_C

    COL_D

    COL_E

    COL_F

    GEOMETRY

    This table contains a number of objects point.  With the help of Mapviewer, I can successfully create a map by using the HTML5 API.  Here is an example of how I used the constructor 'OM.layer.VectorLayer.TYPE_JDBC' to retrieve the objects point of my database.

    pointLayer = new OM.layer.VectorLayer ("PointLayer",

    {

    infoWindow: true,

    def:

    {

    type: OM.layer.VectorLayer.TYPE_JDBC,.

    dataSource: "myDatabase",.

    SQL: "SELECT * FROM POINT."

    geometryColumn: "GEOMETRY."

    labelColumn: "COL_A."

    loadOnDemand: false,

    URL: baseURL

    },

    renderingStyle: circleMarker

    });

    How can I use the HTML5 API to access the data in the other columns (COL_A, COL_B, etc.) of my table?

    I know that the methods DisplayInfoWindow() and displayTabbedInfoWindow of the Map class to view this information by clicking on a specific point on the map.  But I would like to have access to all the points to create a table below my map showing all points (and their data) shown on the map.

    Hello

    You can try this code:

    functions var = pointLayer.getAllFeatures ();

    for (var i = 0; i)

    {

    Features [i]. GetAttributes() ["COL_A"];

    Features [i]. GetAttributes() ["COL_B"];

  • Windows 7 SP1 w/IE 11 freezes, slow performance with switching webpages, downloads, games run very slowly and when to play simple games (for example, CandyCrush Saga) it ignores the graphics and music.

    I have an older Toshiba Satellite laptop I found that, after buying new laptops, I return to my only older because of its speed of travel from site to site, download and never had any problems with games.  I was running Windows 7 Home Edition, IE 9.

    About a year ago, I decided to upgrade my Windows 7 Home Edition to Windows 7 Professional and updated my browser IE 11.  Laptop still has a large.

    Then about 6 months ago I started to receive messages when you enter a Web site that I need to install Flash Player to view the page.  I checked my modules and Shockwave or Flash Player have been activated and would download it again to display the Web site (which I had already visited several times without any problems).  This has happened on several different sites.  Then I started to receive messages that I needed to upgrade my IE8 browser to a newer version.  I checked HELP to make sure that I still installed IE11 and I did it, I started getting these messages more often then I went to the aid of Microsoft Office on what to do if your Web pages telling you to upgrade.  Basically, IE11 is reset or uninstall IE11.  Reset is not good so I tried the method of reinstallment.  I uninstalled IE11, went to the download page for Microsoft IE11 and proceeds to download IE11.

    I saw a message that I couldn't download IE11 because I need to Windows 7 SP1 or later or Windows server 2008.  Then, I went to Microsoft requirements for the installation of Service Pack 1 for Windows 7 and follow-up procedures one (i.e., uninstall Adobe Acrobet, disabling Microsoft Security Essentials and Windows Defender and firewall, etc.) and after the installation of SP1 for Windows 7, followed all procedures to know what to do after the installation of SP1.  Downloaded all the updates (which were more than 120) restarted and was satisfied with fluent how my laptop worked once more.

    After a week, I noticed my phone to talk more and more to load pages and would begin to get Windows Explorer "unresponsive".  It started with almost everything I opened and I tried to edit Web pages or click icon to redirect me to another window, I kept receiving "not responding".  Rose (Microsoft), what to do and monitoring tools to try to fix the problem.  Initially, the problem was to find for a few hours, then starting upwards.  After a few days, my laptop almost took 30-45 seconds to switch between the tabs or windows.  After a search through questions and answers in the Microsoft community and Microsoft Web pages, the bottom line was reinstall Windows 7 SP1.

    Yet once, uninstalled and reinstalled Windows 7 SP1 and again ran perfect for a few days.  I turned on computer laptop yesterday and noticed that it took a long time for the upcoming Windows logo and has a black screen for a few seconds before the logo appears.  Of course, out of nowhere, I went to IE clicked icon and took forever to get to Yahoo (which is my predefined Web page).  Each page, I'm going to again is freezing, "not responding" and very slow operation.

    It is so frustrating because I added not all programs at all.  I am running IE11, Microsoft Security Essentials, and that's all. Outside of Windows Defender, firewall, Explorer, Media player, etc..  Microsoft Security Essentials (I did a full scan) has detected no viruses whatsoever and I 264 GB 285 GB free on my C: drive.  Therefore, there is no problem with the free space.  I have deleted the old files, temp files, analyzed and defragmented my hard drive and am just lost as to what is the cause.  All my drives are underway and have no conflict with all devices.  If I go down my Windows Professional so I will not be able to download anything higher than IE9.  I love IE11 and am happy with Win 7 SP1 if only he would stay longer than 3 or 4 working days.

  • Captivate 8 Drag and Drop several legends of text for your comments

    Hello

    I am creating an interaction with an element with which the learner can drag for four different images representing the different categories of data classification.  The idea of the interaction is for the learner to discover each of the four different categories, by trial and error.    I want them to provide comments through text captions that the answer is right or wrong, but each piece of comments will be different and the user should be able to drag the item several times until they found the right answer.  I can't fwork how to do this.

    I just upgraded to Captivate 8 week last, after having previously used Captivate 5.   Therefore, I've never used the installation drag - d├⌐poser and I don't know if he's going to do what I'm trying to achieve or if it's something I could achieve with shares advanced instead, or if it is not possible to do. I tried searching for similar topics, but either did not understand the answer or scenarios seemed different.  I don't really know where everything is still 8 Captivate, and while I have used certain actions in Captivate 5 tip, I'm not that comfortable with them, so simple is good.  The interaction doesn't have to be reported on.

    Is anyone able to help me please?

    Thanks in advance for your help.

    Hello

    According to my understanding, you have a source element that can drag and drop on 4 different targets (different images). For every drop of a sort of legend should appear on stage the feedback to the corresponding user from the target source. (Correct me if I'm wrong)

    This can be achieved with Drag and drop interaction.

    1. Insert the source 4times and overlap each other (since you can drag and drop 1 number 4 times, you must have this element to work as a source of slippage 4 up to 4 items).

    2. make the 4 elements as drag source and group them into a single type. (With the help of add option)

    3. you have your 4 images on stage and Mark as targets of drag.

    4. Insert the rear power legends and put them near their targets. Disable their 'Visible output' flag on Bill pro forma.

    5. now match the Correct ANS on stage.i.e of one of the source type to a target correct years.

    6. Select each target and open their box "Actions of the object". (from Panel drag / move)

    7. uncheck the ' accept all the ' option and the value of count 1. Add the action of 'travel' to show their legends of Feedback now under Drag source Type. (which were hidden). This should be through "Advanced Actions.

    8. now after for each target open the dialog box 'Good years' drag and drop the Panel. (it will be under options and so visible from the source or target is selected)

    9. here under the table, you can see that the value of count is 4. This is to reduce the value to 1. (double-click to change)

    Interaction is now ready. Please don't answer if that's what you wanted to achieve and if you do all the steps above.

    The best thing you can do is to test it with the external monitor. If the external monitor shows your desktop well probably the LCD is faulty. By the same result on the external monitor, the problem may be caused by a faulty graphics card.

    Looks like you may have recently changes your Apple ID you use iTunes on your iPhone.  When you change this ID, you are locked for 90 days.  You can change to another code, but you can download past purchases or save the content on your device until the expiry of this original lock.  When you change IDs the first time it is a nice warning that appears and asks if you are sure that you'll be locked in this ID for 90 days.  There is no way around the lock, other only of waiting.  I think that this prevents you form jittering in all your Apple ID friends and just download all, but that's probably what you're going through right now.  Good luck!
