Exporting Jpeg previews in Lightroom 3

I have some image previews I need to export from a lightroom backup. (The original files are gone and unrecoverable) Does anyone know of a program or plug in that works with lightroom 3? Everything I've found does not work with LR3...

Exported JPEG differs from Lightroom image

Hi all....
When I export my photos from lightroom as JPG, the colors of the photo are dramatically changed. (image looks much colder)
As first, I thought I may be a problem wiht the colour space, but I have try changing them without any success...
Any idea??
Thanks in advance...

Sorry that I didn't answer sooner. I must have missed this thread and your questions.
I haven't started calibrating my monitor yet (I've left it at sRGB for right now), but what I really want is for what I see in Lightroom to be the same as what I (and others) see on Flickr.
The only way to get other people to see close to the same thing as you see in Lightroom is to calibrate and profile your own monitor and export to sRGB. If you have a good monitor yourself, with a gamut close to sRGB, you will get very close correspondence between Lightroom and unmanaged browsers. If your monitor is one of the wide gamut deals or a crappy laptop with a very small gamut, your display in the unmanaged browser will always be completely wrong, even if you use sRGB. Nothing you can do about that. On such displays you basically have to use a managed browser. The Lightroom display will ALWAYS correspond to your browser if the browser is color managed and you correctly calibrated the screen. Color managed browsers include Safari, Firefox (with some problems) and development versions of Chrome.
because my monitors are set to sRGB
You don't want to do that. It is an OK test for a corrupt monitor profile, but it guarantees incorrect color. LR and your unmanaged browser might look the same, but they are both wrong. Calibrate and profile.
If I properly calibrate my monitor, the colors coming out of Lightroom when exporting to sRGB should still be the same as what I see while working in Lightroom, right, or am I better off with sRGB color profiles so that they're always exactly the same?
As I explain above, the colors when you calibrate and export to sRGB will look almost the same in unmanaged browsers except when you have a display with a gamut very different from sRGB. The problem is that under no realistic circumstance can a unmanaged browser show you correct color.

Very dull color of Lightroom exported JPEG

My exported JPEG images from Lightroom turn out to be very dull in prints. My monitor is calibrated with EYE ONE (Color Management System). Used correct color space for the printing company (either sRGB or AdobeRGB) I followed instruction about Export process. But still color is not right. Is there anything I should do to get the same color quality as I see in the Lightroom? I think images in the lightroom show much brighter than they are after print (by printing company like Costco/Blurb/Shutterfly) Thank you very much for your help!

You need to have your monitor fairly dim (80-130 lumens or so) to reproduce color. I thought eyeone actually calibrates brightness but I could be wrong. Most people have their monitors set far too bright. Next, you need to look at your pictures using a good fairly bright lamp with much higher color temperature than most desk lamps. If you are getting dull prints (as opposed to just dark) the likely culprit is the wrong colorspace or bad calibration. Some calibrators simply turn out to be broken. Do the pictures look dull too after export in another managed app such as Photoshop, preview, etc? Lastly, you have to realize that it is simply not possible to reproduce every color you can see on a good screen on paper. This can lead to lower saturation. This is the reason why soft proofing is important, which unfortunately is not yet possible in Lightroom.

Imported NEF appears much different in LR than exported JPEG

Hello there, hopefully someone can help me with this issue. I am using a Nikon D200 w/ LR 2.0 on WinXP Pro. The NEF image I am editing in Lightroom appears much different than what is exported from that image into a jpeg (it does not matter whether it is sRGB, AdobeRGB, or ProPhotoRGB). In lightroom the image is darker and more yellowish than what LR exports from this image. Here is a
link to an image showing exactly what I am talking about. The image on the right is in LR, and on the left is the exported jpeg preview, which looks the same in firefox or windows picture and fax viewer. Just to note, the exported image looks to be correct with what I preview on my camera, LR is what is off. I have also tried all the camera profiles by adobe labs and none of them seem to make things correct. Any help would be awesome, this is driving me nuts because I have no idea what my outputted image is actually going to look like.

The reason why this happens is that Windows has associated an incorrect profile with your monitor. The only way to get a correct profile is to calibrate but you can also cheat and make windows assume your monitor is sRGB (which it isn't). To do this, go to your monitor's properties page, go to the color management tab and delete any profile shown there. This will make Windows assume you have a perfect sRGB monitor and will make Lightroom appear identical to sRGB exports in every other program (even unmanaged ones). They will all be slightly off colour though, even Lightroom, but will probably look like your friend's monitor. After you have done this as a first-aid measure, go out and buy a real calibrator.

Lightroom 4.1 exported JPEG files are not recognized by Apple Preview App

I just started using Lightroom 4.1 Trial version (coming from Aperture). I exported JPEG versions of some images using an ICC profile. On my iMac running Lion 10.7.5 the pictures do not show a thumbnail, the file on the desktop just shows "JPEG". I could not open the file with the Preview App, but I am able to open it with DPP (Canon software)? Also the file shows that it has 0 x 0 dimentions when I click Get Info even though it is about 25 Megs in size?
The message I get is
"The file “Edit-739820120223Canon EOS 7D.jpg” could not be opened.
It may be damaged or use a file format that Preview doesn’t recognize."
Does anyone know why this is hapening?
Is it a know issue between Adobe and Apple?
Is there a fix for this?
Thanks for help in advance.

25MB is quite a large filesize for a JPG, and this might be either quite a lot of pixels saved at a very "high" quality (not very much compressed), or it may be an extremely large number of pixels saved with medium compression.
While the technical spec of the JPG format imposes an absolute limit on maximum width and height pixel dimensions, some software employs a lower limit above which it considers the file to be invalid. Different programs, different limits, sometimes.
I have encountered this (for example) with pano stitched images using the full resolution of a large number of component shots - where JPG output could not be made, or if made, could not even be viewed as a whole by my standard image viewer (though TIFF was still OK even at still larger sizes).
If Lightroom has been set to a large printed size AND to a high ppi resolution, it is easy to get into very high numbers and very large output files. One should IMO at least question the utility and benefit of using very high ratios of upsampling from a standard digital photo - which may happen in some cases as a result of using the same output settings regardless, when spreading the same data across both small and large scales. If the file that was imported into LR really does provide an unusually high number of pixels expressing lots of detail, then that will better deserve such a capacious output file. Otherwise, each part of the file may merely show a very highly detailed representation, of a very blurry nothing-much-in-particular.
If the JPG has exceeded the viewer's size limits, a reported width and height of 0 may represent an error message, in effect - not actual reality.

Exporting jpegs with embedded previews?

For compatibility with a web application I wrote using an old workflow ending with a save-for-web in Photoshop, I need to export jpegs with embedded previews. (Not DNG or other format files with embedded jpeg previews.) This happens by default with Photoshop, but Lightroom doesn't do it and I can't find anything to change that in the settings. Am I missing something? And if this isn't included, is it on the to-do list for improvements?

Hi Andrew,

Exporting Jpegs from Lightroom - DPI question

When I export Jpegs from Lightroom, I set the dpi to 300 pixels per inch. I do not specify a max width or height. When I view these files in Adobe Bridge (CS2 or CS3) the file info says 300dpi. However, when I open the files in Photoshop and select image size, It says 72dpi and has the document size set to very large. I realize that I can enter 300 dpi and uncheck the resample box, I am just confused as to why this is happening.
My concern is, that I upload my images directly to my lab after exporting from Lightroom. Will this cause problems?
Thanks in advance!
David

the image resolution is a combination of the two parameters you mention: size and dpi. a very large size at 72 dpi is equivalent to a small size (like 3x5) at very high dpi. for printing you want at least 240 dpi at the largest size that allows you to keep that resolution. for screen presentations or your web site you want jut 72 dpi. 72 dpi and 2x3 inches will require a very small file size.
I suggest you to export images at TIFF and not JPEG as that will allow you to preserve the image quality when doing editing in PS.
In my case I export TIFF for PS (when I need PS editing) and 72 dpi JPEG for my web site (that way if somebody downloads my image illegally thy get a poor resolution copy). But since LR works very well for me 90% of the images re just kept in raw mode and I print from LR.

Lightroom 5 is not exporting my previews in the catalog, please help!

I purchased Lightroom 5 on Wednesday and had no problem exporting my images from a catalog that included previews and smart previews. Now it is having trouble exporting my previews. I'd tried restarting lightroom, trying different folder, I made sure all images were there, and still no luck. I would appreciate any help!

To be clear: Lightroom (without a plugin) can not (or should I say will not) export "plain" (lib) previews.
That said, if there is a smart preview, you should be able to export.
Are you saying there is a smart preview, but you can't export?
What about if there is NOT a smart preview - still a problem??

Exported JPEGs Distorted in Shadow Areas

I own a Nikon D7000 and I shoot 14bit RAW.
In Lightroom 3.3 the preview images were distorted, only in development mode the images were fine. I reported to Adobe on this and they seem to have fixed this issue.
In Lightroom 3.3 -- and still in 3.4 -- the exported JPEGs are distorted when the exported image is resized:
A lighter version of the same crop (for illustrative reasons):
As you can see, the gradient has serious artefacts, especially when going from green to black. It is a 90% JPEG quality exported of 1050px width. I have seen this for different image qualities (80-100%), though. This does not occur when the image is exported full size.
Can anybody confirm this?
It seems that this only happens for dark shadows.
I had a Canon G9 that I used with Lightroom and I have never seen a behaviour like this. Right now the export is useless to me.

I've had some discussions about this with Adobe folks during the LR 3 beta phase, but that is all behind a wall now. I think they did put in the dithering into Lightroom now. I still think it is your monitor profile. Also realize that the displays in laptops including the MacBook Pros are not actually full 8-bit displays and you will always see some banding in them. See for example this page: http://www.lagom.nl/lcd-test/gradient.php My guess is that that will show banding on your machine in the shadow areas. Also another issue is that you have to look at these displays at precisely the right angle because you will get raised shadows by quite a bit if you look at them just a few degrees off. One thing to do is to use a test image ( I use monitor_test_txt22.png from this page: http://www.normankoren.com/makingfineprints1A.html ). When you squint the image should be uniform. If not slant the display until it looks uniform.

How is the JPEG preview in a DNG used?

The thread at What is the use of preview JPEG embedded in DNG? says that the JPEG preview in a DNG file is not used by any Adobe program. The DNG Converter, version 8.4, says "JPEG previews speed display of rendered images." This statement is on the Preferences dialog.
Which is correct? Do Adobe programs such as Lightroom use the JPEG preview?
FWIW, I deleted the JPEG previews from my DNG files and I cannot detect any performance difference. I thought that Lightroom uses its own preview cache and that may be why I don't see any performance difference. Thanks.

You should have also included the part I said after that: "if you'll want to make "near-raw" quality prints, or have it for future insurance etc." so, actually, in context, yes - they do!
Andrew Rodney wrote:
why have it update until you're finished editing?
To be clear: I was not suggesting it should be updated before you're finished editing it. Although xmp works in just that fashion, I would never opt to have it work that way personally.
My point was that you need to (know and) remember to do it or you'll have an unedited preview, or in any case a stale one, and since there is no "preview freshness" indicator or metadata item (correct me if I'm wrong about that part, but even exiftool can not determine if preview is up2date, right?), you really have to remember, or it won't be done (or complicate workflow with additional metadata to help govern..). Me? - I use publish services to export all such copies after completion - Lightroom remembers which ones need to be exported so I don't have to.
If you use DNG, perhaps a good feature request would be a DNG preview publishing service. I mean, all Lr is really doing is exporting a jpeg but instead of storing it as a separate file, embedding it in the dng, kinda just like xmp.. - that way you just publish your DNG previews along with the rest..

ANN: LRViewer now shows ratings and 100% views; exports JPEGs; customizable

(LRViewer is a free app for the Mac and Windows that allows you to view Lightroom images and metadata without using Lightroom itself. Previously announced here.)
A major LRViewer upgrade, Version 1.1, is now available for download from ImageIngester.com. You can now:
* See ratings (1 - 5 stars) along with the image file name.
* Zoom in to see a 100% view, and then pan with the mouse.
* Export JPEGs with EXIF and XMP info.
This version also includes LRVmaker so that photographers can customize the appearance and behavior of LRViewer for their clients by:
* Placing a logo on the screen.
* Showing a button that goes to the photographer's web site.
* Opening a catalog automatically when LRViewer starts up.
* Starting with a selected collection or other outline item, and controlling which outline items show.
* Marking images with a watermark.
* Preventing clients from accessing EXIF info and metadata, from viewing images above a certain size, and from exporting JPEGs.
For more information or to download LRViewer and LRVmaker, go to ImageIngester.com.

For those of you that have been looking for a tool to 'rescue' your images when you lose your originals, this is it. If you have rendered 1:1 previews, it will even give you that preview from the database. So this is worth buying even if you are just using it as a well designed 'rescue' tool.
Imagine being able to go up to any computer, even if it does not have Lightroom installed, plug in a USB thumb drive, and view a catalog that you put on that thumbdrive. This is what the tool allows. And LRVmaker adds lots of customization if want to leave a copy of your catalog behind for someone else to review.

I have imported and processed photo's in Lightroom 2 and kept stored files on external hard drive. External hard drive crashed....how do I export photo's from Lightroom when it says 'file not found'?

Folders with photo files are lost due to external hard drive crashing. Processed photo's are still in LR. How can I export from LR to a file (any file) that no longer exists? Help!!!

Well, no backups, the technical term for that is "a problem". I think from this point forward, you need to commit yourself to making regular automated backups of all of your photos and catalog file to different physical disks, no excuses.
Your photos are not stored in Lightroom. However, Lightroom does create "previews", this is what you are seeing, but these are usually smaller and low-quality compared to the originals. There are plug-ins that can extract the previews from Lightroom. One such plug-in is here robcole.com - PreviewExporter

RAW and Exported Jpegs in same catalog

I use lightroom to import raw files from my Nikon. Then i edit them and export the good ones to jpeg on my network share for viewing. When i import jpegs from my compact camera i import them directly to my network share. Before i always had the jpegs in to the same catalog just under the other path. But now with face recognitioning i get the face from both places with the exported ones. Is there a way to stack the jpeg with the raw file so that they only show once?

Raw and Jpeg next to each other can be treated as the same file, but only if they are in the same physical folder and have the same name.
Are your exported Jpeg files then re-imported into LR in a different folder? That's a problem for what you want to do (and in general I don't recommend reimporting duplicate images).
LR could do a great job of managing your network share using a published folder, if you included the Jpegs from your compact camera on the loca folder along with the raw images. With publish services and a published folder, LR will create (and remove) Jpeg images in a managed location you choose, and you don't need to worry about reimporting duplicates.

Exporting jpegs-- why do I get 72ppi when i set resolution at 240ppi ?

Why does Lightroom export jpegs at 72ppi resolution-- when I clearly set it at 240ppi in the export window? It has done this for versions 1.0-1.2.
For exporting psd or tiff-- everything works as planned. Anyone have a solution?
Thanks.

Do not click on the minimize metadata checkbox. The resolution is meaningless anyway, but if you want the field uncheck that box.

Exporting JPEGs out of Lightroom3 to be projected on a screen

I export JPEG files via a Lightroom 3 preset to an email attachment and then to be projected on a screen.
The color space setting I use is sRBG. Is this setting the same as sRBGIEC61966-2.1 used in CS5? When projected, my images are soft while they are tack sharp in Lightroom 3 or CS5. A fellow member of my camer club thought that the export setting could be the problem and that he always used sRGBIEC61966-2.1 from Photoshop CS5. Any suggestions to resolve this problem?
rbg

That's the correct color profile for typical computer displays.
If you are using LR's built-in "email" preset for export - then that's your problem. This preset makes for small email attachments, but poor image quality. It deliberately scales your image size down to 640 x 480, which is just 0.3 mega-pixels (same resolution as bad cell-phone cams). It also compresses image quality to only 50%. No wonder they look bad when blown up large!
You should find out what resolution their projector runs at (typical sizes are 800x600, 1024x768, or 1280x1024). Export your pictures at that size or larger, and choose at least 80% quality setting or higher.
