JPG export,  what am I losing?

Hello,
I have noticed that Lightroom exports as JPG are significantly smaller that with other RAW image processors (namely DPP, Lightzone, Capture One 4). Should I be concerned? (quality is set to 100 in Lightroom).
Thanks.

Thanks, everyone.
Opening the image in ProPhoto colorspace completely eliminates the blue clipping. When I compare two instances of an image in PS after assigning ProPhoto in ACR for one and Adobe RGB in ACR for the other, I see much more detail in the blue channel of the image in PS.
Yes, then this is a good lesson on gamut clipping and colorspace.
I tried the workaround but it's much easier to just work in a larger colorspace.

  • JPG export preset in InDesign?

    Hi all,
    Is there a way to save my JPG export selections as a preset? I have to export JPGs of the same document for two different purposes and they have different export requirements. Is there a way to save my selections as a preset the same way I can save my PDF export selections as presets?

    Cheers,
    Trish

    I'm pretty sure it won't be your fault, but I don't seem to be able to fix it. Try this one but it exports the number of pages squared!  For example a 4 page document gives you 16 jpegs, 5 = 25 and so on.
    What am I doing wrong John?  I added in this line: app.jpegExportPreferences.jpegExportRange = ExportRangeOrAllPages.EXPORT_ALL;
    //Display a "choose folder" dialog box.
    if(app.documents.length != 0){
    var myFolder = Folder.selectDialog ("Choose a Folder");

    myExportPages(myFolder);
    else{
    alert("Please open a document and try again.");
    function myExportPages(myFolder){
    var myFilePath, myPageName, myFile;

    var myResult = myDialog.show();
    if(myResult == true){
    //The name of the exported files will be the base name +
    //the page name + ".jpeg".
    var myBaseName = myBaseNameField.editContents;
    //Remove the dialog box from memory.
    myDialog.destroy();
    //Generate a file path from the folder name, the base document name,
    //page name.

  • Extremely large jpg exported files - help!

    I was previously loving LR3 - used the trial for a month, decided to buy it - had really no problems.  The big issue for me is now the jpg export file sizes that are being created.  I run all my photos through the develop module to adjust the basics as well as draw in masks, and previously I had no trouble exporting the files as jpg, with the limit of size at 600kb and resized to 960x640 (original photos from 5Dmk2 RAW). 
    Then I bought the license.  From then on it seems that now whenever I do the same exact export it doesn't work!  I also used to use the output quality slider and set that at 100% and would get around the same file sizes, but now I'm getting files 2-3x the size of the previous exports.  All of the photos have minimal metadata (10 keywords or so, that's it) and the same metadata was present in the exports in the trial version.
    Playing around with more export parameters and reading around on this forum led me to try and minimize exif data - this didn't even work - files could not meet the requirements or they still ended up 2-3x the size they used to be. 
    The interesting part is that when I would delete all development history and set the file back to the original pre-edited RAW and export there would be no problems!
    Could it be possible that LR is adding the development data into the metadata that it is attaching to the photo??
    This has completely shut down my photo workflow and really is making me regret buying this otherwise wonderful tool.

    This data results from heavy use of the local adjustment brush. Choosing "Minimize Embedded Metadata" upon export really should solve this problem for you. Please try again specifying this option.
    But then, by doing so, you lose any other metadata (keywords etc.) also. To have complete control on what metadata gets written into the JPEG upon export, you could use Jeffrey’s “Metadata Wrangler” Lightroom Plugin.
    I noticed one strange thing within the XMP data in your JPEG:
    The data seems to be formatted differently than what I see with JPEGs I export ("HasExtendedXMP"), which I don't know where it comes from.
    For further investigation, would it be possible for you to upload the Raw file and the XMP file belonging to it to somewhere (e.g. www.yousendit.com) and post a link to it here?

  • Keywords missing in LR2.3 jpg exports.

    My jpg exports do not contain the keywords and captions that I entered in LR2.3. What am I doing wrong?

  • JPGs exported from Lightroom 5.6 will not open in other applications

    Recently I have noticed that jpgs exported from Lightroom 5.6 can not be opened in Canon DPP 3.14 and can not be resized using Image Resizer plugin. Both of these I use frequently.
    I have seen mention of this issue re other applications also. Does anyone know if there is a solution?
    I am using Windows 8.1 64bit. 5D Mark ii

    This was an issue with 5.5 (the placement of some of the internal headers of the jpgs was changed and some other applications, including DPP, could not open them), but was corrected in 5.6. I just checked on it by exporting a jpg and opening it with no problem in DPP 3.14.15, Windows 7 x64. Are your jpgs old ones from LR 5.5?

  • Multi-threaded JPG export

    The slowest portion of my application is the conversion from a generated INDD file to JPEG. More CPU power seems to be the only solution at this point, but because IDS is single threaded, 3 of the cores on the server sit idle during this.
    Is it possible to implement a plugin or Javascript script that exports each page in a separate thread, or similar, thus using all available cores during the export process?

    Hi,
    I think it is possible in InDesign 5 via "asynchronousExportFile".  You can also create multiple server instances and let each instance generate a jpg export.

  • When exporting what does kind mean?

    hey guys
    just curious when exporting what does kind mean? also if its a video from iphoto should i use original? All the other times i did  JPEG. is that why my videos turned into JPEGS?

    see this user tip for details (user tips are accessable under the uper tips tab in each forum)
    And yes to export a video you use kind = original
    All the other times i did  JPEG. is that why my videos turned into JPEGS?
    Yes - the reason you got a JPEG is because you told iPhoto to export a JPEG

  • Palette for JPG export

    Hi!
    When I export BMPs with the "Layers to files" command, I can
    control the number of colors by creating a palette.
    Can I do the same thing when exporting JPGs "Layers to
    files"?
    I have not found a way to do this in Fireworks and the
    work-around conversion program I use changes the ppi of the image
    so it is useless.
    I need JPGs because it is the only format my hardware device
    (simulation platform) can read and I need it in 256 colors to
    simulate what it will look like on the final product. Please help
    me!
    Great forum by the way!
    Kind regards

    export it as a gif and choose your palette there, then open
    the gif and
    export as a jpeg at 100% ?

  • Why is Aperture2iLife so fast on jpg export when compared to Aperture?

    I shoot youth sports.
    On most days I can shoot 1000+ images for 3-4 games. I shoot 70-200mm VR on a D2X in high-speed crop mode to get eight frames/sec so the shots add up fast. Occasionally I switch back to full res but for the most part I am shooting eight frames/sec every time a ball is in motion near kids.
    I carry a D200 with a 12-24 for wide and close shots.
    All jpg of course, and have found that it is good enough for even 16x20s.
    Most games get culled down to 100-200 images. Those keepers are then cropped, white balanced, exposure adjusted, and sharpened. Lift and stamp make that work go very fast.
    I then export preview images to post on my photo ecommerce site. This is a killer... sharpening, highlight and shadow adjustments can triple the output times. For a project of 200 images, it can take 30+ minutes for output. If I have 3 games per night I am looking at 1.5-2 hours just for outputting preview images! No I don't want to use automator running my DP G5 into the night...
    HOWEVER, I have just tried added something new into my workflow. Aperture2iLife.
    After I am done with culling, cropping, correcting a project, I exit Aperture and launch Aperture2iLife, select "create jpgs" which outputs images that are 1024 pixels on the long side, select the project I just finished in Aperture and two minutes later I launch iWeb.
    In iWeb I pull up the media browser and select photos. I select all and drag them to a empty directory in finder.
    30+ minutes versus 2 minutes. WHY?
    Granted, Aperture2iLife is a quirky app, and does have some issues, but for what I need it to do, it SMOKES Aperture.
    Why do I edit the preview images? Better preview images sell more.

    That's because under teh covers, Aperture is making three different sizes of preview thumbnails - including images that are 1024 pixels on one side.
    Aperture2iLife is cleverly just pulling out the JPG files Aperture has already made.
    Aperture has a few features that make use of these larger thumbnails - in Slideshow you can elect to use these images for faster loading, and if you delete a master image it uses the thumbnails since it can no longer generate an image from the master file.
    I agree it would be kind of handy to havea feature to let you simply export those largest thumbnails directly since for web use, that's generally large enough. But then again Aperture2iLife does that pretty well already.

  • White frame in JPG export

    If I choose at AI, the export, to jpg option, and tick the use artboards option, the exported jpg will get a rather thick white frame.
    The document has no stroke, if i export without the use artboard option there is no problem.... any suggestion?

    What are the contents of your artwork? Is there a background with stroke applied? Please explain a bit more about the artwork so that I can suggest something.

  • Exporting RAW to JPEG, losing EXIF data

    Hi,
    When I am exporting a RAW image from Aperture to a JPEG image I'm losing metadata. Specifically: Lens, Serial #, Flash exposure and focus data. I always select 100% JPEG with the "include metadata" checked.
    Any suggestions or is this a bug?

    I know this is an old thread, but I have the same problem and am hoping perhaps to get some new feedback.  I also have used all the same settings,
    the best quality settings that I can do on export, but the quality I get when I convert to JPG is very poor. I do save at 100% because I want to send some of my images to stock agencies that want JPGs but at the very best possible quality.  I have experimented in changing the resolution to 300, resizing to 18MP (which is the native size from my camera (Canon 7D), leaving the resizing box unchecked, and tried all all levels and types of sharpening, and none of these settings makes any improvement.  I honestly do not think this is an issue of color calibration.  The images that I get when I convert from RAW to JPG are are very poor quality, but not so much noise as they appear pixelated.  I am going to try to attach a screen capture of a RAW image and a JPG that has been converted.  Realize there is a bit of loss of quality in both of these images as they were done by the print screen function, then saved as BMP and then JPG..But doing it this way actually produced a much better quality image than exporting the RAW file to JPG in LR3. Both of these images were saved at 100%
    The image at the top is a small segment of the RAW capture at 100% and the bottom one is a segment of the same area of the exported JPG at 100% Note the writing and how it is very pixelated. I think you would agree that it is quite a deterioration in quality.  Any suggestions you have would be greatly appreciated.
    Thank you.

  • Original size Raw to JPG export not exporting correct size

    I'm having a problem with the export of RAW to JPG at original size. I have raw images of 4941 × 3295 (125mb), when I export selecting "JPEG-origional" size I get resulting jpg's of 800 x 533 (95kb) 
    If I select JPEG-50% of original size I get correctly exported images of 2471 × 1648 (589kb)
    Why would the original size export not work?

    Have you checked the "JPEG original size" preset? Select the preset on export, then switch to "Edit" and see, what is selected. Sometimes this preset is redefined to a smaller size.
    When you edit the preset, the "Size To" pop-up should be set to "Original size". If it is not, set it back.

  • Issue with JPG export

    Hi at all,
    i have a problem when i try to export a jpg image.
    I must do a small image for a Exchange signature.
    When i exported the file in jpg with save for web and i insert it in exchange, the dimensions (width and height) are ok, but less quality.
    However if i save normaly in jpg the quality is the top but when i insert the image in exchange, the dimension are strange, there isn't width and height correct.
    The file is a 72 dpi.
    What's mean?
    Where i'm wrong?
    Thanks a lot!

    What size is the file?  Believe the web changes to 72 dpi, but if size too big perhaps they are downsizing?
