sRGB vs ProPhoto

I have a question about the color space that has been bothering me for some time that I can't find an answer.  Basically, with respect to the sRGB, ProPhoto, AdobeRGB and my editing in ACR, Lightroom, Photoshop, etc.  I don't know if this is important to any passage to ProPhoto when 95% of the instructors there are representative the sRGB gamut and include the AdobeRGB?

If my assumption is wrong, then I'm happy for someone to explain and to help me understand how it is important to have my value ProPhoto software and work with a monitor that is at best AdobeRGB.  Of course, I do not use sRGB for nothing but export, so the importance of the issue is for editing.  As a side note, I recently bought a new 4K display during my research, I read about the sRGB vs. AdobeRGB display space, and so ended up buying an LG which has space AdobeRGB.  I have traditionally used space ProPhoto with the EDITION of Photoshop.  I spent from 'down' for AdobeRGB, for editing I thought that maybe it's better if everything is set for the same space.

I understand also printing can come into play, so that my photos published are either exported through jpeg online and then printed by this host via their sRGB/jpeg, or print a TIFF directly from Lr or PS file.

Thank you for your time and attention.

The main advantage of ProPhoto is that it gives you the margin in the editing process. You can work without running to the break from which you cannot recover from the range. Once a channel is cut, this information is lost.

For final output, ProPhoto is illogical since no output device cannot reproduce the range. You will have to remap anyway and the necessary remapping can be very broad.

I said in another thread that the ProPhoto range is essentially artificial, which means that these very saturated colors are rarely in real life. There is actually an interesting concept called for "Gamut of the pointer", which represents all real colours reflected by a solid object, as seen by the human eye. It happens to fit quite comfortably in Adobe RGB:

With respect to the monitor, a unit of the range ("Adobe RGB") is very useful for proofing, because it can reproduce virtually all printable color - inkjet or offset. This means that you can test with confidence. A standard unit is much less useful in this regard. Everything you see on the screen is already flexible soundproof in sRGB and lots of printable colors are out of gamut of the display.

  • Strange things happening to the sepia images in Lr 4.3

    I am at my wits end and hope someone can help out me! I spent hours and hours with tech support Adobe to have a hard time to understand thick accents and not enough knowledge to understand the question. And my case was dropped because of schedules; I was busy with Thanksgiving that seemed to make no difference for the one who is not celebrating! But I digress...

    I don't really remember what happens in Lr 3.5, but it's in Lr 4.1 - 3 and the only effects Sepia toned images that I modify most of the time. Just finished about 200 images of an event where I'll put them on a DVD to music for the purchase. They all was going well when I'm done with them. I exported to JPEG, the side long 1024, quality 74. The rest of the short iMovie, long history made looks terrible, co-opted to iDVD. First time visualizing everything was good, but after several viewings after reorganization/add/remove images of the project, they look crap. For some very strange reason, many takes a pink/reddish color and often introduce artifacts that were simply not there in Lr I watched my images edited on 2 different Mac and the question remains, so not my computer.

    I have an iMac 27 ", OS 10.6.8 (completed to date), 3.3 GHz core duo, 12 GB RAM, 960 GB of free space on a 1 TB HARD drive. Warranty the display and the recalled hard drive have been replaced, so my 4.3 Lr is completely fresh; not from a backup. With the new recent HARD disk, I have not calibrated my computer at the moment. My images are on a WD 3TO with 1.25 TB of free space (a bit on the low side, but should not do anything). My camera is a Sony A33 and strictly I shoot in RAW to sRGB; using ProPhoto in Lr and for a while now that in the manual.

    I would be grateful if someone can explain why it is a problem. I need to finish with this DVD for the event, and if I can't understand this point, he has lost time and money! It is true that I did not this very long, so if this is something I am doing wrong, I would really like to know what that is...

    The trick is to select the pictures (or its VCs) work and export a new catalog of this (file-> export of catalog). Be sure to deselect "export negative files ' and"(Inclure aperçus disponibles) '. " Then load the new catalog (you can just double click on it.) Previews will be re-created in this new catalogue.

  • 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.

  • Conversion of ProPhoto RGB profile sRGB. Major SHIFT of color

    Hello
    Just had a nightmare experience with print lab. Picture a) with Lightroom ProPhoto RGB profile completely different color image duplicated b) from Photoshop in the sRGB profile. When you open the Lightroom file in Photoshop, it keeps the ProPhoto profile. With Lightroom Preferences dialog box indicates that the profile should be ProPhoto not sRGB. If I convert profile after the opening image upward in photoshop for the worse color changes. However, if I change the profile in Lightroom preferences all is fine.

    So what am I supposed to do? Y at - it somewhere where it is explained in easy to understand English and no tec?

    Oh my. I thought you said convert?

    No, never give up. This will change the colors. Entitlement is used if you get images without any embedded profile - or, very rarely, if you think that the file has the wrong embedded profile. Entitlement is really an option expertise - leave it alone unless you know what you're doing.

    Convert to profile is what you normally do.

    Oh, and it's always a bad idea to 'play' with the Photoshop color settings. That will lead you inevitably more and deeper problems. Yet once unless you know what you're doing, always keep the color to the default settings. That "works".

  • Should images in Bridge are different from each other? sRGB vs ARGB vs ProPhoto?

    I am looking for some clarification on this because I'm at a standstill and going bonkers.  First of all, it's a long story how I got here, but to shorten, I had to buy a new screen, my old one crapped out.  I bought a screen wide range NEC and then need a new graphics card so bought a new HP workstation and then because of the external drive connection problems had to reluctantly upgrade to windows 8.1.  So I'm not sure where the conflict lies from the new to the foregoing.


    My old set up worked fine, I managed ARGB color.  Prints from my printer and laboratories corresponding Photo on my monitor calibrated.  I sold a lot of pictures and everything was good.   I've always used Bridge and PS, I found import into Lightroom bulky... .so it has not been used much.


    Now, I love Lightroom, but all my images are not importing, so I always use with bridge for display. I like to see images in Bridge for comparison and approval.


    My dilemma is here... Many of my images look different in Bridge and change before my eyes, never had that happen before.  Sometimes images differently Tags are sometimes similar, they are different and they change.   Why not compatible?  and what if they look like?  For example, to be clear.  I have 2 different images and each of them is duplicated and labeled in each color space.  sRGb, ProPhoto and ARGB.  A single image they all look the same, the other images, they all look different.   Why?

    If I change the settings of ARGB color for general use they will not always vary all over and over again.  I have conflicts somewhere... but it cannot narrow down.


    My goal would be to bridge to show me pictures sRGB as tagged tagged ARGB and sRGB images to resemble ARGB and Pro Photo images to look like pictures of ProP.  It is naïve to me who?

    The first thing you need to know about the bridge, it is that it stores all the previews JPEG sRGB, regardless of the original color of the file space. IOW they should all be the same under any circumstances.

    However, the preview properly on screen rendering often takes a bit of time. Usually there is a brief initial moment where you see the file without color management, before bridge has the time to convert the preview in the monitor profile.

    It should quickly snap into the correct view. But sometimes it hangs and stays in the State 'without color managed", on the one hand, several or all the previews. When this happens, the quick solution is to right-click and 'Purging the Cache for Selection'. It will then refresh correctly.

    You haven't noticed this with the standard range, old screen - it would have been anyway sRGB to sRGB (ish). But with a range wide screen, it becomes obviously oversaturated.

    Changing the color settings makes no difference. Profile embedded which - replace and like I said the bridge previews are sRGB in all cases.

  • Should I convert Prophoto RGB to sRGB in the Lightroom print module?

    My question is about my image sending over for my Epson printer via the Lightroom print Module: when I'm ready to print from Lightroom (after the back and forth-Photoshop and back) I have a final image in Prophoto RGB ready to print. Lightroom manages print colors (not the printer). I'm supposed to do a final conversion of ProPhoto RGB to sRGB in the Lightroom-print module, before sending it to my printer Epson R3000? If yes I can't find how do in the print module.  I just sent the Prophoto RGB image for the printer Epson R3000 via printing from Lightroom module being (Lightroom manages color, not the printer). Am I missing a final in sRGB conversion and all simply not seen how via the print module?

    PLEASE READ:

    (1) I KNOW do Lightroom and the paper profile, manage the color and not to let the printer manage. It all works very well.

    (2) I KNOW not if I export a jpg on the web (do not print) convert to sRGB in the export dialog box.

    (3) I correctly my color spaces selected as ProPhoto RGB in my preferences of Lightroom and Photoshop, everything works fine.

    (4) my EIZO monitor is calibrated, I use appropriate document profiles.

    Forgive me if listing these things seems obnoxious, it is not my intention. I find that give lots of information is useful to those who might respond.

    Thanks in advance.

    Jim

    I've never felt the need to convert. I have mild in using the profile paper appropriate to the evidence and then let Lightroom it's thing. Is there something wrong with the prints you do what makes you think that you need to convert?

  • My color, setting for LR and PS is ProPhoto RGB. If I want to export my photos and place them on OneDrive or watch on TV of the photo, can I change the color setting in sRGB?

    My color, setting for LR and PS is ProPhoto RGB. If I want to export my photos and place them on OneDrive or watch on TV of the photo, can I change the color setting in sRGB?

    In general, I would recommend sRGB, if images must be consulted on the screens of TV or PC monitors. sRGB is usually the universal profile for sharing photos on the web. If you want to share your images on a single disc, most of the people will see their best, without changes in color, with an sRGB profile.

    So it really depends on your goal. You use a player for sharing and viewing on backup and storage devices.

  • Why "Saved for Web" ProPhoto RGB files with "Convert to sRGB" show picked up as "no label" after registration?

    For years, I managed my entire workflow to sRGB, thinking if I can make a picture look in sRGB, it is gold in another color space.  Lately, however, I started shooting in Adobe RGB and control my image in ProPhoto RGB.  When I save an image for the web, using the menu item "save for Web", then check the box that says "Convert to sRGB", the images are fine, but when I check the color profile in Bridge, it says "Untagged", not sRGB IEC61966 - 2.1, as I'm used to.  I'm doing something wrong, or is this normal?

    Thank you!

    Which version of photoshop and the operating system are you using?

    In the Save dialog box for web you have embed color profile verified in addition to convert to sRGB?

  • Confused about ProPhoto vs. sRGB

    I realized that by default LR4 will export to sRGB when I save a file out of it.  I'm confused, this is what I get using the ProPhoto recommended for space when I send to ch instead for more editing?  PS I updated the same space so to match, I am not sure of what I earn.  I guess I won't have to worry about conversion after that I did because I'd just edit in PS back to LR4 to export or print the finished .psd file?

    The idea is to keep the same colorspace LR uses so that all the editing - life photography, in this way, that you keep the range from the photo, and have more space to change, even if you can't really visualize this space of color on a normal screen (or even a fancy). It's as if we were working on 16-bit vs. 8-bit. Most monitors cannot handle even 12 or more, but you know that the data is there and the software can work better and produce better results on a larger workspace.

    If you were to convert to other space and edit later on Photoshop, you will be put to scrap some (or many) of the info. It can be visible or not, depends on the type of photos you are working with.

  • 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.

    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 ".

    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.

  • Should what color settings I choose for photoshop ProPhoto RGB, Adobe RGB 1998 or other?

    Please tell me what color settings should I use to apply on Photoshop and Lightroom. ProPhoto RGB, Adobe 1998 or another? Thank you.

    If you work mainly for printing AdobeRGB seems a good choice, if you work primarily for the web, I would recommend to use sRGB.

  • 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.
