What color space are the Color Lookup presets meant for?

I've noticed that if I convert the same image to multiple color spaces and apply a 3D LUT with the new Color Lookup adjustment, the result is noticeably different.  From experimenting, it seems that the lookup tables operate on whatever RGB value is given to them no matter what color space.  Is there a certain color space these were optimized for?  For instance, would a certain color space give me a more authentic 2-strip look than another because of the space they were sampled in?  And if I create my own 3D LUTs, would I have to create a separate one for each color space in order to get a consistent look in all spaces?

So do you know what color space was used to create the presets that are there, such as 2-strip and 3-strip?  Even though they don't know about color spaces, the different gammas on the input cause the look to come out different in all colorspaces, so it stands to reason that whatever color space the calculations and/or sampling was done in is closest to what was intended while the others are rough approximations.  For things like "warming" it doesn't matter, but for ones that simulate actual films I'm curious to know, especially since the 2-strip ones looks a little different than when you just copy the green channel into the blue and green channels as described on all the websites.

  • How to set PS for the most reliable image previews and how to make sure the color spaces are the same across plateforms

    I've been having an ongoing problem with some of my images changing color/luminance values after merging or flattening an image. This seems to most often happen if I use one of the filters (like crosshatch or notepaper, not sharpen or blur). I can make a copy using command/option/shift + E which most often will look exactly like what's on screen.
    Some people have suggested that it's to do with resolution, PS showing me a low resolution image but I don't think so because the histogram changes -- sometimes in a big way, but most often those spikes in the luminance levels are shaved off. Also, when I have the image open at 100% and effect a merge/flatten, the color changes.
    I'd like to know if there's a way to have PS show me one for one what I'm working on while I'm working on it, or if there is a way to control the color profiles when I'm saving. My best guess at this point is that there is a color profile mismatch going on somewhere. I just don't know where to look for it.
    Typically I work in 16 bit, so my color space is set to ProPhoto RGB; my camera is set to the Adobe color space;
    color management policies are set to preserve color profiles;
    conversion options --> intent is set to relative colorimetric.

    But it is calibrated. I use Xrite 1 and update it every month (on the first).
    The colors can be really off. Here's an example.
    https://flic.kr/p/r6A1Zd (what I want) https://flic.kr/p/qc5QTD (not what I want)
    Also, I can't see how the bit depth will have any effect since the change in color happens in PS when I merge or flatten. It's 8 bit through the editing and 8 bit when I flatten it.
    Have you any suggestions on what I can do on the computer side?

  • Why are the colors in Illustrator and Photoshop so off?

    Hi,
    Let me just start off by saying I have the color mode in both Illustrator and Photoshop set to RGB. Yet, there is a noticeable color difference between a picture on the internet and when I paste it in for example Photoshop.
    Picture from the internet:
    Picture when pasted in Photoshop:
    It's the same thing in Illustrator. And this is not just with pictures by the way, it's affects all the colors I use, which is a major pain in the rear.
    Anyone know a fix?

    Well, my suggestion in post #13, was to help me find out what the cause of your problem is. It doesn’t solve your problem permanently but temporarily, only for the current session of Photoshop or Illustrator by making these programs show your image without applying any color management conversions.  So, you have to do this every time you open such files in these programs.
    If you want to understand what is going on and be in control, you have to go through a lot of walls of text unfortunately .
    I’ll try to explain it roughly but if you don’t understand it you need to read more about color management.
    You are using Safari and this is how its color management  works:
    https://developer.apple.com/library/safari/technotes/tn2220/_index.html
    on that page it says:
    "Important: For images that are not tagged with a color profile, their color values will be displayed on the screen by Safari with no optimization or adjustment for differences between devices in how they render colors. This may result in the colors not being displayed as originally intended"
    This made me think that like most images on the web, the image you are using doesn’t have a color profile. In that case, assuming a certain scenario based on your input, the reason it is displayed differently from Photoshop and Illustrator is because you have a color profile of your monitor used by your system that is different than the color space used for the display of the image. By default RGB Images without a color profile are displayed using  the color space set for the working space in the Color Settings of Photoshop and Illustrator. Also by default this color space is sRGB.  If your monitor was also with an sRGB profile assigned in the system, which is the case with all monitors that come without a color profile provided from the manufacturer, you should have not experienced this problem because Photoshop and Illustrator will see that the color space you want to display your image is sRGB and your monitor is sRGB, and there will be no color conversions because both color spaces, source and destination are the same.  Unless someone else has setup your system ,color management, and installed a monitor profile,  my guess is that the manufacturer of your monitor has provided a color profile installed in your system that is not sRGB.
    When you choose View > Proof Setup > Monitor RGB, this in effect turns off the color management because you are displaying the image in the same color space as the one assigned to your monitor.
    If you want to turn off the color management permanently which will be valid only when displaying images in the sRGB color space, you can assign the sRGB color profile to your monitor. This will show the images on your monitor with the same colors as those displayed without color management in the other applications and choosing View > Proof Setup > Monitor RGB will make no difference.
    Non color managed programs can display the color only in the way your monitor displays it. Color managed programs simulate other outputs on your monitor. The only way to match the display in color managed and non color managed software is to turn off the color managed software. This will display the same color values with the same color in all programs on your monitor.
    The purpose of the color management is to allow the viewer  see the colors as intended (the way the creator sees them when creating the image). Different devices and media output the same color values differently resulting in different color. Therefore, when the viewer uses different device or media the colors if not color managed properly will look different or not as close as possible.
    When you turn off the color management, or even when it is on but not properly applied, which I suspect is the case in your situation, you can’t be sure that the colors you see are as intended. In other words, you can’t tell if an image is supposed to look the way you see it, and you can’t create images providing means that will allow others to see them the way you see them. 
    So, for whatever reasons you want to make colors look the same in all your programs, have in mind that this is valid only on the current state of your monitor, and this also cuts the possibility to see and send to others colors as intended.

  • TS4337 Why are the colors for my calendar reseting to a color I never chose?

    Why are the colors for my calendar in iCal reseting to a color I never chose?  It won't stay blue when I choose that color and keeps changing to a custom lavendar color on its own....  Incredibly annoying...

    There doesn't seem to be a one-size-fits-all answer, because what works for one printer doesn't necessarily work for another, and I don't have your printer so I can't advise on specifics...
    However, perhaps we can discover a set of settings that will work...
    If you File - Print, choose Photoshop Manages Colors, in the Printer Profile section do you see profiles specific to your printer (e.g., with the name Kodak in them)?
    If so, choose one of them that seems appropriate given the paper you're using.
    If not, try choosing sRGB IEC61966-2.1.
    Now, before you continue, press the [Print Settings...] button.  This brings up the printer driver dialog.  You may have to go through [Advanced] buttons or whatever, but what you're looking to do here is to disable the printer driver's color management logic.  In other words, if you can find a color-management / ICC profile handling section, set it to "no color management" or equivalent.  OK back out to Photoshop's print dialog, then press [Print].
    The key here is that if Photoshop manages the color transforms, the printer driver should not be set to do so - or vice versa.
    If you're presented with the printer driver's dialog again, double check that the settings you chose above are still set, for good measure, and try a test print.

  • How to organize the sample color grid in the Color box?

    Do you have any tips/tricks to keep the small squares of color in the Color menu organized? These are the color samples that you pull from the color bar at the top of the box and that you drag onto the grid for future reference. I have been willy nilly dragging squares of color onto that grid and it works fine for short term work but I cannot remember what square was for what if I have left that page and need to return to fix or change something. The only thing I can think of is to make a paper graph and notate on that hardcopy.
    One thing that I have been doing is, for colors that are hard to distinguish, I load the tiny squares onto FOUR grid squares to make one bigger square of the sample color.
    But..... does anyone have another way?

  • Why are the adobe pdf presets grayed out in photoshop?

    Why are the adobe pdf presets grayed out in photoshop? I'm trying to save an image to "Press Quality" as a pdf and the settings are grayed out.

    Maybe a screenshot of your Photoshop working area with the image opened, image tab and the layer panels showing might give us an idea. I can't guarantee that I can help, but someone might be familiar with the situation.
    Also a screenshot of the Save as Adobe PDF and the PDF settings dialog as separate shots would also help as well. That way we see what you see.

  • What are the Corresponding fields in CRM for sales order in ECC

    HI! Experts,
    While creating a standard sales order in CRM I want to poulate these fields in ECC Sales order, these fields are
    VBKD-BSARK - Purchase order type
    VBAK-BNAME - Name: user ordered
    VBKD-IHREZ - Web Confirmation Number
    VBAK-TELF1 - Telephone number
    Or the other way round I want to know what are the corresponding fields in CRM for these fields so that when I pass the data in crmd_order in those fields it gets populated in the above mentioned fields.
    Thanks and Regards
    Mayank

    Mayank,
    May I suggest you to create an Order in R/3 with these fields and check that back in CRM. This is not as easy as it may sound. It is possible that some of these fields are "determined" by the system - for example the "Sold-To"'s first telephone number maintained in VBAK-TELF1. So, though it becomes a part of the Order header in R/3, CRM, generally doesn't duplicate them in the transaction but allows to refer back to the master data from the transaction!
    Check the following fields in CRM and see if you find the data you require.
    VBKD-BSARK - Purchase order type There is a field in CRM that "holds" this value. ACTIVITY CATEGORY. This can be found in the ACTIVITY_H set of the transaction. Filed name CATEGORY. Problem with this is, - "Category Type" of a CRM Activity to be mapped to PO type? Didn't workout good for us since the master data for both vary widely. So, we used custom Header Extension data for this (EEWB). So, you have to work
    VBAK-BNAME - Name: user ordered Is usually CREATED_BY in the CRM Order Header (CRMD_ORDERADM_H). But this fills up the VBAK_ERNAM bit not the BNAME.See the next item, that may give a clue if this is related to the next item.
    VBAK-TELF1 - Telephone number is usually "determined". Usually the Sold-To's first telephone number maintained in the Business Partner "Communication" section for that Sold-To.
    VBKD-IHREZ - Web Confirmation Number Actually it is Customer's or vendor's internal reference as per standard use. Looks like your customer is using it for custom purposes. Well, if you maintain the relationship  "Is Correwspondence Recipient for" with the Sold-To partner in CRM, and maintain the details of this Person, then this will be transferred to R/3.
    Hint: Once you have the R/3 order in CRM, try using the Report program (SE38)  CRM_ORDER_READ in CRM. This is a good tool to "dissect and see" and order in CRM. The program needs only the Transaction Number as the input.

  • What are the best settings to use for the newest AirPort Extreme (AC wifi) with my optimum online service provider?

    I have the current generation of the AirPort Extreme and a handful of devices that utilize the new 5Ghz A/C frequency. My internet speeds were blazing fast when I had first set it up but lately it has been lagging terribly. I was told that changing my dhcp did help, which it did it seems like it might be back to its normal speeds but I just want to know what are the best settings to configure for the airport so that I can get the most out of my service on all my devices? I'm using a CAT 6 cable which does help, I have a guest wifi setup with a wifi password which I understand will slow it down a little. Can anyone just point me in the right direction or just give me a step by step guide on what settings to configure? Should I really consider turning off the guest network?

    I am assuming that you are looking to configure your network to provide the highest level of bandwidth possible for your network clients. If that is the case, the following are a few things to consider:
    The Internet modem should support Gigabit Ethernet. That is the Ethernet connection between the modem and your 802.11ac AirPort Extreme should be Gigabit Ethernet.
    Use CAT-5e or CAT-6 Ethernet cables between all wired connections.
    Only expect 802.11ac performance with 802.11ac clients in the same room as the base station.
    Eliminate or significantly reduce any forms of Wi-Fi interference on both the 2.4 & 5 GHz bands.
    When streaming, especially HD video on your local network, use wired connections between the host and player devices when possible.
    Other than the above suggestions there are no "magic" settings that you can make on your AirPort. Note: The Guest network shares the same bandwidth as the "main" network. Unless you have a network goal to provide this type of network, it is best left disabled.

  • What are the 3-bit field choices for Hw_Arm_Sel in PCI-6601

    Hi,
    I am programming our own driver to operate the PCI-6601. For our application we need hardware arm option. I know it is possible to use 2 counters for that, but NI-TIO should support also hw_arm. Although it is not explained in the registry document at all, after some tedious check in the DDK examples I found that this bits are located in the Gi counting mode register. I know the position of the HW_enable as well as the position of the 3 bits for pin sellect options. What I do not know is What are the 3-bit field choices for Hw_Arm_Sel . I contacted NI support but got no support. How can NI sell boards and when a customer who is not using LAbview or Measurement Studio or DDK, but is implementing his own driver is then so arrogantly turned down from NI? Also, how can NI publish just part of the registers the board support, and when a customer contacs and asks for some registers get not at all support? I can not foretell the missing registers, and it is pretty unprofessional to document just partly the registers of 660x devices. And on request you got nothing.
    I hope someone from the community know about this Hw_Arm_Sel 3 pin options. Otherwise, there is just an option of error and trial. Or simply throw the board in the garbage.
    Dr. Kirco Arsov
    Solved!
    Go to Solution.

    Hi Kirco,
    I have some more information for you :-)
    I haven't been able to speak to the developer who is the most familiar with TIO programming since he's out of the office, but I have come across his notes from when he was writing support for the DAQmx driver.
    As I described earlier, the HW_Arm_Sel bits don't select a connector I/O pin, but an internal trigger signal. There are seven internal trigger lines, and the HW_Arm_Sel bits map directly to the internal trigger signal: 0b000 - 0b111 map to 0d0 - 0d7. In order to route an I/O pin to an internal trigger, you must also write to a few more registers.
    From what I've read, there are two more register families that need to be programmed: TG_x_LevelEdgeReg and TG_x_CombinationReg, where x is the internal trigger number. In your case, you only need one pin from the I/O connector to be your arm start trigger, so TG_0_LevelEdgeReg and TB_0_CombinationReg will suffice for your application.
    TB_0_LevelEdgeReg :: Offset 0x660
    TG_0_LevelEdgeReg is only 8 bits wide, and maps as follows:
    7..6: EdgeMode
    5..0: LESel
    LESel selects the I/O connector pin to use as the source for the internal trigger signal. 0d0 - 0d39 will select the I/O pin of the same number. NB: behavior for TG_x_LevelEdgeReg is more limited for triggers 1-7, and only a small subset of the I/O pins can be selected for those trigger signals. Trigger 0 can use any I/O pin. Setting these bits to 0d63 forces the trigger source low, and can be used as a way to 'unroute' it when you're finished with your program.
    EdgeMode determines whether the TIO will detect an edge of the incoming signal, or just pass the signal level straight through. When detecting edges, it will latch the signal and generate a single TIMEBASE3 pulse instead. 0b00 sets level mode; 0b01 sets rising edge; 0b10 sets falling edge; 0b11 sets either edge.
    TG_0_CombinationReg :: Offset 0x6A0
    TG_0_CombinationReg is 32 bits wide, and has three fields of interest:
    19..16: CombFunction
    5..4: CombTypeB
    1..0: CombTypeA
    CombTypeA controls which trigger subsystem to use as the source for the trigger signal. Since you're coming from an I/O pin and using the edge/level subsystem, you must set these bits to 0b01.
    CombTypeB is similar to CombTypeA, and although you won't be using trigger B, set it to 0b01 to be safe.
    CombFunction performs a simple logic function on A and B. Since you're only using a single I/O connector, you only need the A output, so set these bits to 0b1100.
    All of the other bits should be set to 0b0.
    Unfortunately, I'm unable to test these statements since my test machine is currently being used for another research project. Please let me know what happens if you decide to test.
