Projector problems using Lightroom

I am a photography teacher in Germany. The school recently purchased a new high-end (HDMI) projector (40,000 Euros) The quality is incredible. The projector works perfectly when using PowerPoint and Windows Photo Viewer. When I open Lightroom, the projector periodically flashes on and off. The projector works perfectly for all the other teachers in a wide variety of applications. I need to find a solution to this problem as Lightroom represents my tool of choice for post processing. Below are my system details.
Computer and OS:
HP EliteBook 2760p
HP Docking station using a DisplayPort to HDMI cable to the projector
Windows 7
Lightroom 5.3
The IT staff at the school are very good and they do not know what is happening. I have tried several different cables and nothing appears to fix the problem.
I look forward to hearing from you,
Jim

To clarify, PowerPoint and Windows Photo Viewer work with YOUR laptop connected and only LR has an issue, correct? Does LR work at all and if so in what modules, how soon do you see the flashing, what color is the projector screen, is it displaying a message? It sounds like the HDMI handshake is getting dropped for some reason. My first suggestion is to refer to the user manual, online troubleshooting on the manufacturer's website, or contact the projector manufacturer's tech support. Also make sure you are using a "Certified" HDMI 1.3 cable form a name-brand manufacturer of no more than 3 meter length.
Other things to try:
Set the projector in Lightroom as the 2nd display (1 and 2 icons in lower left-hand corner). You may need to use Windows display setup Guided Help: Dual monitor setup is easy in Windows 7!
You might also try installing Lightroom on another laptop or desktop and see if the same issue occurs.

Problems using Lightroom wtih external Hard Disks

I having some problems with the latest Lightroom 1.2.
I import images (NEF+JPEG) onto my internal hard drive and everything is fine. Images look good and thumbnails display NEF+JPEG at the top right.
However , as soon as I move them onto an external drive (using lightroom) I start to have problems. First the thumbnails display JPEG+JPEG. Then all the images become wildly oversaturated and contrasty without me doing anything. Moving the images back to the internal HD (using lightroom again) causes only the JPEG files to be moved back. Of course the wild colour stays the same.
FYI I am using a Macbook Pro, 2GB RAM, OSX 10.4.10. External HD is 500GB with 150GB free

mmm, I have a similar problem - I bought a hard drive as my i-tunes library was eating up space on my laptop. It was fine at first, but now when I add cds it updates my i-pod no problem, but if I try to create playlists it says it can't find the tracks. I've tried consolidating my library but it didn't work. I'd be interested to know if any of the helpful suggestions you get work.
Good luck and sorry I can't do anything other than sympathise.

Problems using Lightroom and Bridge/PS

I use both lightroom 3.6 and bridge/ps how do i manage my files because i have all of them working fine in bridge/ps but not working at all in lightroom , all it says is "file missing" when i open an image
thank you

If you move or rename photos or folders outside Lightroom, then you get the ? icon indicating that Lightroom cannot find the photos any more. You can fix the problem via the instructions here: http://www.computer-darkroom.com/lr2_find_folder/find-folder-old.htm
Hint: don't move or rename photos or folders outside of Lightroom from now on
Hint 2: I think one of the problems you are having is that there really is no benefit, and perhaps significant drawbacks, to using two different "organizing" software at the same time, Bridge and Lightroom. You might want to stop using Bridge, as you can do all of the organizing in Lightroom from now on

Problems using Lightroom 4

I have been using Lighroom4.3 for nearly a year now with no problems. All of a sudden, it refuses to import any of my NEF files from my SD card. I have tried all my SD cards to no avail. In the import window the files appear as thumbnails, but when I ask to import I get the message 'Files were not imported because they could not be read (3)'
Any one know what the problem is? My camera is a Nikon D3000.

I'm importing into a new folder so permission has not been revoked.
That doesn't make sense. Each folder can be set to different permissions - at least on Windows it can.
Please check the permissions for the folder and/or the drive you are importing to carefully. In Windows it should be set to <Full Control>, on Mac its <Read and Write>.
Also, check if there is enough space left on the drive you are importing to.
The error message that you are getting includes the reading that Lr does of the imported file on the drive (so-called "backreading"). Backreading is done to make sure that the file on drive is correct.
This message points strongly that the drive or folder does not have sufficient permission. If it is set to <Read only> the import won't be possible.

Problems using Lightroom 3.2 in new pc laptop

Hi ,
I just installed lightroom 3.2 in a new laptop.
In my old laptop ,I had my photos and catalogue on external 500gig hard drives.
When I plug the Hard drive into the new laptop and click on the catalogue to open it ,not all of my setting have come across to the new machine.
For Example ,User presets in "Develop Module" and Metadata presets,copyright info etc are missing.
Can i someway export these settings so that Lightroom has the same presets etc on my new laptop without entering the information again?
Also , a second question.
If i was to use the internal 500gig hard drive in my new laptop to work on photos on location/in the car etc(im a press photographer).
What is my best way of taking them and backing them up to external hard drive later? Can i just drag and drop folders of photos to an external desktop hard drive or should i use some program and if so any recomendations?
Many thanks for any suggestions.

Problems with Lightroom 5.2 and Olympus EM-1 RAW files?

There have been reports on DPREVIEW of color problems using Lightroom 5.2 with RAW files from the Olympus OM-D EM-1 camera. This causes difficulty creating camera profiles, and creates a red shift in Images. JPG images are unaffected.
Anyone else seeing this?
When may we look forward to LR 5.3, hopefully with a fix?
Thanks............... Jack Winberg

The read me file from Adobe indicate that LR 5.2 has "preliminary" support for the Olympus EM-1 raw files.
I would make sure you keep your original raw files so they can be converted when the support is finalized. i.e. I would not convert to dng on import if that is your normal workflow.

Hi, I am having a little trouble with exporting images to another drive and Catalogue and need some help if anyone can give me some advice
I am currently using Lightroom 5.6 and operating on a Mac with OSX Ver 10.9.5.
I am receiving an error problem when doing the following -
I am exporting selected photos from a particular Catalogue saved on Drive 1 to a folder created on another Drive where a Lightroom Catalogue has been created. In this Catalogue I have arranged for the images once exported to be moved to a different folder - I used the Auto Import process under the File dialogue box.
When processing the Export I receive an error message for each of the images being exported indicating the following -
Heading Import Results
Some import operations were not performed
Could not move a file to requested location. (1)
then a description of the image with file name
Box Save As Box OK
If I click the OK button to each image I can then go to the other Catalogue and all images are then transferred to the file as required.
To click the OK button each time is time consuming, possibly I have missed an action or maybe you can advise an alternative method to save the time in actioning this process.
Thanks if you can can help out.

Thank You, but this is a gong show. Why is something that is so important to us all so very, very difficult to do?

You have SCADS of extensions and the things running. McAfee, Intego, Orbicule, CleanMyMac, and others I've not ever even heard of. My first recommendation would be to remove all of these and see if things improve.

Have been using Lightroom on my Apple computer for years. Now, ever since upgrading to Apple's Yosemite operating system I get an error message (150:30) every time I try to open a lightroom file. Has anyone else experienced this problem? Also how do I subscribe to Adobe's Premium Support? Every time I've tried (through contact support) I just get taken on an unending loop.

I think we need a lot more information.
Exactly what does the message say?
Exactly what files are you trying to open?
Exactly how are you trying to open them (what menu command or button or mouse action or keyboard shortcut)?
And lastly, what version of Lightroom are you using?

I am using Lightroom 5 and am hapy about it, but recently I hav encountered a problem when trying to edit an image in another program, i.e. Elements. I used the clone tool, saved the result and went back to Lightroom to open the image there. I did find a second copy, but this is identic with the one I already had in Lightroom, and I can see noe result of the clone process.

At the moment I would say it is uncertain whether Acrobat is completely ignoring the change, or whether the changes you are making aren't affecting the ink density. I have a suggestion for a test you could make to see which is the case.
When editing in Photoshop just add a box or mark on the image, for your tests.
- If this box does not appear in Acrobat, you know Acrobat is not seeing the edit
- If this box does appear in Acrobat, you know the problem is that your tool for changing ink densities is not taking effect.

I had never problems wih installation of lightroom. suddenly lightroom refuses to start when I try to from a picture i have taken with my nikon D500 and transferred to WINDOWS 8.1. i have tried to re-install lightroom : the procedure asks for the serieal number , but refuses to accept the number that always worked. PLEASE help!! jan

If you are certain you have the right serial number, there really isn't much we can help you with here. You might try downloading and installing the last version of Lightroom 2. It will be the trial version, but when the trial screen appears there is an option to indicate that you have a serial number. Incidentally, Lightroom serial numbers start with the first four digits being 1160.

Problem with Lightroom and Infrared Photography

This problem is specifically related to using LR & PS to process Infrared images. I apologize if this forum may not be the correct place to ask this question. I am having problems processing Infrared Images when using LR & PS. I take my IR images with a 530 IR conversion to a Canon G12 camera. I learned early on Adobe products don't play well with IR images (they come in magenta when importing ) so I bring IR images shot withmy G12 into my computer with Canon Digital Photo Professional and then work in LR & PS from there.
If I then directly open this imported image from my hard drive into Photoshop and try and do adjustments such as blue sky adjustments with a red/blue channel swap, it works fine, just as I would expect.
(If you are not familiar with IR processing, I understand this introduction and question will not make sense)
But when using Lightroom, I sometimes have issues. I always import all my images into LR. Even with IR images, after using DPP to bring them to my computer, I import them into LR for cataloging purposes and to make other potential adjustments. Then my usual workflow is to move photos from LR to Photoshop via the "edit in" command. This opens a dialog box giving a choice of "edit a copy with LR adjustments" which is the default option and the one I always use, or "edit original".
Here's the interesting thing I finally discovered.
If I send the photo from LR to PS using the "edit a copy with Lightroom adjustments" option, I get a bad blue sky effect, where the sky is green and the foliage is pink instead of the sky being blue and the foliage yellow. But if I send it to PS using the "edit original" option, the blue sky effect works fine.
So there appears to be an issue when tring to send IR images from Lightroom to Photoshop. Any thoughts?
Thanks,
Matthew Kraus

Thanks so much for working on this.
I fear the behavior you noticed was just due to the fact I cheanged the
file from 16 bit to 8 bit so the size was smaller and I could easily email
it. When I open any of my regular 16 bit files, whether I send them to PS
as "edit original" or "edit copy with lightroom adjustments", they both end
up as 16 bit and as far as I can see, seem the same, though obviously they
are not.
I don't really have a preset, but I'll walk you through the process.
1. Choose Channel Mixer from the Adjustment Pannel
2. Make sure the output channel is red, change the red channel slider from
100% to 0% and increase the blue channel slider from 0% to 100%. You can
type in the values.
3. Change the output channel to blue. Increase the red channel from 0% to
100% and the blue channel from 100% to 0%.
This is supposed to change the sky from brown to blue and the foliage from
blue to yellow and is what happens when you use the "edit original"
option. When you use the "edit copy with lightroom adjustments", the sky
turns green and the foliage pink. So you get 2 different behaviors,
depending on which option you use to bring the image from LR to PS.
That's my question, why do you get 2 different behaviors?
Thanks,
Matthew Kraus

Could not complete the command because of a problem using the Adobe Color Engine

Hi all
This bizarrely started this morning - completely out of the blue - and I've no idea why.
Setup: Mac 10.8.2 / Creative Suite Premium PhotoShop CS5 extended (patched to 12.04)
Am working on images exported from LightRoom 4 (16bit A3 Pro Photo RGB PSDs) in PhotoShop CS5.
As part of my image grading process I have a PhotoShop Action that does the following: copy layer to new document (document respects all of copied layer settings) > Image > Adjustments > HDR toning > apply a certain HDR preset > copy to resultant image back to original doc > set opacity as 40%.
Totally out of the blue, after having this action for about 2 months, this morning I start getting a warning dialog of "Could not complete the command because of a problem using the Adobe Color Engine" and the action fails. The failure seems to take place at the 'make document' part of the action and seems to somehow be related to the contents of the clipboard.
I've tried trashing and re-creating the action. It works first time out fine and then - on the next image - errors again.
At present I can only safely carry out the work 'manually' by completing all the actions myself.
I can think of no settings that have changed and the OS hasn't been updated in a while.
I have found one other thread on a similar problem in PhotoShop Elements, but no definitive solution.
Any help appreciated as I have a shedload of stuff to process.
Best wishes
TP

OK: trash of prefs didn't work. Tried thrice. Re-created orig action. same problem.
BUT!
Your 'Image > Duplicate' suggestion does seem to work. If I use that in a new action as the method for creating the HDR version doc (instead of 'Select > Copy > New > Paste), it seems to work.
Will try that out this afternoon, but for now: WIN!
Many thanks for the suggestion!

I am using Lightroom 5.7, 64 bit with Windows 7 Professional. For no apparent reason, I now get an error message when I export a photo, say a raw image to a JPG. However, the exported image seems to be OK. But now I notice that my LR directory of folders in Library view does not show images correctly: If there is a folder with sub-folder(s), the folder will indicate 0 images, but the sub-folders show the proper number of images. What happened and is there a fix? I tried uninstalling Lightroom and re-installing, but problem persists.
