Preview and EXR images - linear light

Everytime I Quicklook or open an openEXR image in Preview, it looks very milky. Like Preview is using Linear color space.
I have to open my image in After Effects or Photoshop to look right. Is there any way to get Preview to use a gamma curve?

Hi, Network:
This a serious flaw as I see it. Apple claims OS X to a superior system and to have numerous graphics routines built into the OS to make it a superior platform for those who work with graphics.
DNG is a great format proposed by Adobe that should be fully supported by Apple and OS X. The most interesting thing is that there are some DNG images that Preview will open. I currently have one in my hard drive that Preview can open (shot with a Canon Rebel digital camera and converted to DNG - don't know what software was used for the conversion).
However, I have tried to convert numerous TIFF and JPEG files to DNG using Adobe's Lightroom and the newer Adobe Bridge CS3 with Camera Raw v 4.1 using various different settings but none of the files produced can be opened by Preview.
How can I escalate this technical issue to a higher level technical support consultant at Apple ? I consider this to be serious enough to warrant this type of action. I am sure Apple could easily write an update to its software that would provide support for DNG files. There are numerous professionals out there experiencing the same problems and running into this same obstacle.
Any ideas ?
Thank you again for your help,
Joseph

Preview and Actual Image

When I am adjusting or filtering an image I get a preview box and the actual image changes behind the box to however I put the settings to, so I use it to see what its going to look like. But when I press "ok" it turns out completely different than it was in the previews. Why is this?

If you have other than 100% view you can get a view that is not true. Try this with 100% view and see if it preview and actual image.

Preview and Thumb image in MXP Upload

I've noticed that other content types allow users to upload a
Preview and a Thumbnail image when uploading their extensions. It
seems that this option is only unavailable to MXP extensions.
Is there any reason why we cannot upload these images with
MXPs also? It would be beneficial from a marketing standpoint, but
also from the perspective of understanding the extensions before
downloading.
I'm interested in learning why this feature has been removed.

If you are using a Container you just leave your image files in the home directory of your web application. And forget this idea about database. It´s not necessary in this case.
To display the images just use HTML, <img src="url">.

What happened to my previews and images?

Calling all Wizards,
Was working in Lightroom 3.3 (64bit) on Windows 7 yesterday when all my previews and the Images went missing. The files and the catalogue entries are all still there (i.e. Metadata, keywords etc).
The thumbnails are grey and when you click on the image or try working in the developer module or any other for that matter, the image is grey. Zip, Zilch nudder.... or in polite english, no image.
I tried loading other catalogues, same issue.
I tried repairing Lightroom (i.e. re-install option), no change.
The only time I can see a thumbnail is in the import screen during a new import and there after, once the image is imported. No preview or image.
No luck at all trying everything I know to fix it.
Any help is really welcome.

Your monitor calibration profile may be corrupt.
For testing, please reset the profile to the systems default sRGB. If this helps, recalibrate your display.

Lightroom CC and GPU previews and exports

Hi,
Does Lightroom CC uses the GPU for creating the previews and exporting images, or just for interactive adjustments in Develop?
thanks,
Misho

GPU is only used in the Develop module and not in any of the other modules. There is a new Auto setting for previews in LR6 preferences which is the default if using LR6 for the first time. If upgrading it's recommended that you change to the auto setting and standard previews will be optimized for your monitor.

Preview and print does not match image in LR

I tweaked an image in Develop and printed some 5x7s until I got it right and then went to 13x19 (first time ever using that size with my R3000). The print preview and the print were way too red. I went back to a 5x7 and it was way red as well in print preview, so I didn't print. I replaced a light magenta cart that I think ran out during the 13x19 print, and then some others that were low, and did a nozzle check and that was okay. I have spent hours looking around all of the settings (sRGB) and can find nothing that would explain what changed between my last good 5x7 print and the red 13x19. I went back to earlier versions and had the same problem. Monitor is due for recalibration, but that probably has nothing to do with it since it changed so suddenly. Any ideas of what to do? R3000, LR 4.3, Win 7, NEC PA 271w, beginner level

A print that is too red / magenta is an indication for double color management, i.e. by Lr and by the printer.
Color management must be done only by one: either by the application (Lr or Photoshop) or by the printer but never by both.
When you select a printing profile in Lr that means that now Lr is doing the color management. Consequently you have to switch off colo rmanagement in the printer dialog (printer driver).
See screen shot:
Or, you can do it the other way round: Let the printer do the color management and select <Managed by Printer> in Lr.

Big Colour and detail changes between Original Nikon RAW files and the images created on the Preview page!

Big Colour and detail changes between Original Nikon RAW files and the images created on the Preview page! Yes there are distinct visual changes when I preview my Nikon NEF RAW Files.Please note I do not use iPhoto at all.
If you view it as a contact sheet straight from the original folder there are no alterations but the moment you double click and want to 'Preview' it, this new preview page introduces very noticeable distortions : lighter shading goes missing and colour goes darker e.g orange turns red and mid blue goes deep blue! Alarmingly the little column on the left of the preview page showing the collection shows the original file colours and then after a few seconds show the new distorted image...you can see this visible change and it takes place after a few seconds once you double click! Also if you use Apple's 'Cover Flow' to preview, this function will replace your original RAW file with the new 'altered preview' image!
I have raised this with Apple but they have yet to reply...has anyone ever experienced this? I have used my Mac book for 18months only noticed it about 5 days ago!
I went to Apple store and we tried it in other laptops and Macs and it happened to all of them so we think this is a software issue and not down to the laptop.
Any help is much appreciated!

Preview and safari do not display images in a pdf, where as chrome will. How do I fix this?

I'm on the newest OS X Yosemite and I have an issue with viewing pdfs in both preview and safari. The figures show up fine from Chrome. This also leads to the issue of when I try to print off the pdf. The images do not appear in the printed version.
Safari/ Preview:
Chrome:

Back up all data before making any changes. Please take each of the following steps until the problem is resolved.
Step 1
If Adobe Reader or Acrobat is installed, and the problem is just that you can't print or save PDF's displayed in Safari, you may be able to do so by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar should appear under the cursor. Click the printer or disk icon.
Step 2
There should be a setting in its preferences of the Adobe application such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected.
Step 3
If you get a message such as ""Adobe Reader blocked for this website," then from the Safari menu bar, select
          Safari ▹ Preferences... ▹ Security
and check the box marked
          Allow Plug-ins
Then click
          Manage Website Settings...
and make any required changes to the security settings for the Adobe PDF plugin.
Step 4
Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
/Library/Internet Plug-ins
In the Finder, select
          Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens by pressing command-V, then press return.
From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari.
Step 5
The "Silverlight" web plugin distributed by Microsoft can interfere with PDF display in Safari, so you may need to remove it, if it's present. The same goes for a plugin called "iGetter," and perhaps others—I don't have a complete list. Don't remove Silverlight if you use the "Netflix" video-streaming service.
Step 6
Do as in Step 4 with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari.

Preview and image capture don't save imported scanned image

Hi. Both preview and image capture aquire the scanner and displays the image overview. But when proceeding
to scan, the application simply hangs and no image is saved.
Maybe some prefs file is corrupted. Tried removing the com.apple.Preview from ~/Library/Containers, but didn't help....
What to do???

Not sure if this is relevant:
1) TWAIN-BRIDGE is installed otherwise mavericks won't talk to the scanner.
2) recently added an HP printer (no scanner). Shouldn't conflict with the scanner driver, but then again.....

Preview and Image Capture Not Recognising Scanner

Preview and Image capture have stopped recognising my networked Canon MX350 scanner. It seemed to occur after I used PhotoScore to scan some sheet music but that could be coincidence. I deleted the scanner driver and reinstalled it from the Canon website together with the MP Navigator software, and I am now able to scan from MP Navigator but not Image Capture or Preview. I have run Software Update but no updates are available.

Apple's official documentation only provides an information about printing by using this device - scanner is not listed. I would suggest to look for specific drivers on Canon's official webpage.

I am not able to import photos into Lightroom 5.7. When I select a folder, it doesn't show a preview of the images and the import button is greyed out. ??

I have been using Lightroom 5 for 2-3 months now and all worked well, up until today's effort to import a new set of photos. I am working on a Mac with Yosemite 10.10.1.

Go to the bibliothec module, select the folder, right click on the folder and hit synchronize
Sorry I have only a german version , so don't know what your menu will show.

Losing links of images on Preview and Publish.

Some images are not linking on Preview and Publish (Beta7). I have relinked (even going back to the original in Photoshop) and re-published again, those link up but then other images stop linking and do not load. Ones that were working fine just minutes ago.

Hi COLBY,
Here is the link to a recently published site. On the Publish I did about 30 min. before all the images were loading. Now on this page two are not. When I wrote the question yesterday 6-7 images were missing, randomly. One than publish again three, than more. Since yesterday I went back to a earlier saved version and made some minor type changes and links, not involving any of these images. The first time I published today, all the images were linked. It seems the longer I work with the file the more images seem to disappear. I have only had this problem since I updated to the Beta 7, on Friday. http://amberart.businesscatalyst.com/cockroaches.html
Thanks.

Aperture not working to get import previews and thus import images

I cannot seem to get images to appear int eh Import Window's preview pane, and thus cannot import them. I have some 1600 images from a recent shoot in a sub-folder on an external drive (in two locations actually) and Aperture is not hunting them down. I have tried importing files on the desktop as a test and the same problem, no previews and no chance to import. All my OS and Aperture updates are installed and I did a restart to no avail.
I know that this version of Aperture, along with the user manually select to not import into a New Project (grip for Apple dev if they are reading), that previews take long to load and freeze the Import process on my setup. So, it could be that it is taking forever to get 1600 previews, but viewing them in a finder window shows no problems getting previews.
Any pointers as to what the problem might be?

I have occasionally had this problem and found either waiting a while or cancelling the Import and then retrying the Import (and being patient) works.
The workflow I use includes giving a custom master/version name to the appropriate images from the camera, such as "Judy in the Garden", importing those pics of Judy, and then supplying another master/version name, such as "Punch Drunk" for the appropriate images of Punch, importing those, and so on. So it can take many iterations to pull all the images in. Often the imports work as you would expect but then suddenly, nothing appears to happen and cancel and I redo it. My suspicion is Aperture is busy doing some housekeeping or other (or hung) but since a retry or two does the trick, I don't worry about it.

LR 4 - image does not appear in Preview and will not print`

The selected image appears on the main/center panel but not in the preview screen. Printing results in a white sheet of paper with no image at all. The image has been updated to LR 4 - but made no difference. I've served help and the forums (where i saw mention of similar problems, but no comments or guidance on the problem). What am I doing wrong?

The problem began with the installation of LR4. I print directly from LR4 to my HPZ3100. I routinely select "print preview" in the print dialogue box. Now the first print I see the preview and then it prints. If I select a second print job and use the "print preview" the print preview screen comes up blank and never loads. If I try to delete the print job, it just never responds (resolves) so I have to turn off the computer and the printer and restart to clear the print job. if I don't use the print preview, it prints just fine (except that I'm not able to check what's about to be printed). Thanks for any thoughts you have on this.

Bill, if this is only happening some of the time, then we are probably looking at a resource issue. Any pattern in when things won't print? e.g. Certain file type won't but others will? Or is it more of a timing/order thing? e.g. First file prints fine, second does not? VStromee, do no files print for you? Or is it like Bill and sometimes the print and other times they do not? Did you install any new software recently or have any updates to the OS or any application that has printing capabilities?

Why are some jpg images scrambled when they appear in my screen saver? The same images look fine in Preview and Finder. Some images appear scrambled in the screen saver 'preview' window and the actual screen saver. Other jpg images look fine.

Why are some jpg images scrambled when they appear in my screen saver? The same images look fine in Preview and Finder. Some images appear scrambled in the screen saver 'preview' window and the actual screen saver. Other jpg images look fine.

The desktop image is fine, taken from the exact same pool of jpg photos. However, as soon as the slide show screen saver comes on, the images are scrambled. What is it about the apple screen saver algorithm that scrambles the pics?
