Black thumbnails and inconsistent previews

This has long been an issue with Aperture for me, I use Aperture 3.5.1, OSX 10.9.4 . Editing photos sometimes has the previews stuck on a few places, sometimes when exporting photos to jpeg or just simple editing I get a black photo. To fix it I had to disable some of the editing blocks and renable them, this is very annoying and sometimes I had to restart aperture.
Seeing that Aperture stopped development I wonder if bugs like this will ever be fixed?

ARRRGGG, this is stupid. Apple leaves Aperture with all it's bugs and leaves everyone behind. No updates, no fixes. I want my money and time back!! >:(((

Black thumbnails and negative images after import

I'm experiencing a problem with iPhoto 6 and some images importing with black thumbnails and negative main images.
I've tried replacing the sRGB Profile.icc (it wasn't missing for me), but that didn't work.
Any suggestions?
1.83 GHz Intel Core Duo Mac OS X (10.4.5)

Are those negative images B/W photos? If so they may be Grayscale mode. Download the "Embed sRGB Profile" Automator application form Toad's Cellar and drop the original files for those photos onto it. If it's a grayscale mode file it will correct the situation. iPhoto 6 does not play well with Grayscale images.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Black thumbnails and pictures in Media Center in PE8

Hi,
I've had this issue for years (in PE6, 7 and now 8) and on various Windows versions (XP MCE, Vista and now on W7 x86 and x64) but I've finally decided to try and do something about it as I'd really like to be able to use the MC plugin.
As the title says, some of my pictures appear black (both the thumbnail and the picture itself) in Media Center. All my pictures are fine in the desktop version of PE8. It seems to happen exclusively with pictures that are taken vertically (portrait orientation), those in landscape are fine. But some portrait pictures (though very few) appear fine too. I've also found out that if I open a "black" picture in the Editor and save it (without changing anything), then it will appear fine in MC. And I've noticed that it's only happening with my camera (Canon Ixus 860 IS) although I had the same problem with my 2 previous cameras (both Canon PowerShots). The memory cards were different too.
I'm pretty baffled by all this and I really don't know what I could do to sort this out. If anybody has had the same problem or if anyone can think of a solution, any helps would be greatly appreciated!
Here's a picture to illustrate what I'm talking about:

My suspicion is that your problem correlates to a photo orientation indicator set by your camera in the photo file.
some ideas
--Choose one photo which displays black in Media Center
-- In the PSE Organizer thumbnail area, select that photo and display the Organizer Properties panel/window for that photo. within the Camera Data of that Properties window you are looking for an Orientation field - what does it say ?
-- Now in the Organizer, rotate the thumbnail of that same photo 90 degrees to the right or to the left and then rotate it back in the other direction
-- Do whatever you may need to do to refresh your display through Media Center and check if this photo displays OK.
After you post back with your results, we can discuss in more detail the what and the why. If my theory is correct the solution should be easy.
FYI - I suspect that your identifying that the problem was specific to portrait photos which had not been edited will be very significant in identifying what is happening. Good analysis.

Black Thumbnail and Picture

When I import some photos that I scanned (doesn't happen to all) into iPhoto some of them show up as black as the thumbnail and when I click on them they show up when expanded. Also, some of them stay black...even when I've imported a perfectly fine jpeg file it sometimes shows up as black. What do I do?? How can I fix this??

Thank you for your reply. No, they are full color pictures.
I think I found a workaround.
The pictures were in JPEG format. I opened them up and saved them in JPEG-2000 and that seemed to work fine. The pictures don't seem to be as vibrant, but that's ok.
Any other ideas as to what the heck's going on? There are some .tif images that are screwy as well.
Thanks!

IPhoto 9.3 shows black thumbnail and preview

When I import picture in portrait orientation iPhoto 9.3 creates black previews and thumbnails.
Is this a problem of iPhoto 9.3?

People have been reporting this for a while now, with no fix at this time.
Many folks find that rotating the image and then rotate it back will get them a thumbnail.
iPhoto menu -> Provide iPhoto Feedback and report it.

Black thumbnails and pictures

Hi all,
I've been having this problem lately with my iPhoto, when I try to import photos into my iPhoto from only one particular camera (my other camera when importing photos does not have this problem). All the vertical photos come up as black, also the thumbnails. I have also been referring to this previous thread for help as it's the same problem - https://discussions.apple.com/thread/3413585 - but none of the suggestions have been of any help. My camera is not on auto rotate, and i know that iPhoto does not do this itself, but I know that the camera's auto rotate function has already been disabled. I know that the files are not corrupted because the 'original file' is there and looks fine when I look for it manually in the finder, but I don't know how to change iPhoto so that it doesn't automatically modify the vertical photos and replace them with the modified photo. I am also trying to rebuild the library now, but it's taking hours.
Any thoughts? Any help would be greatly appreciated!
Cheers

Lightroom 4 video black thumbnails and playback

On loading I see thumbnails for avi videos for about a second and then they go black. On playing in Lightroom the screen is black but the sound is fine. The videos play correctly in Quicktime and other programs.
Any suggestions on how to fix this?
LR4 Windows 7, Core i7, ATI Mobile Radeon HD5850, 8Gb RAM

I used a video conversion program to convert to a different codec. It probably does not need a full codec pack installed, just the coded changed. Google 'codec changer software'. I have not tried any of the free ones so make sure that you make a copy of any file before converting it if the program overwrites the original file.

Black Thumbnails & Previews

I've had a problem pop up recently, a number of my pictures are now showing up with black thumbnails and previews. I have tried everything, deleting and re-generating both, repairing permissions, rebuilding database, even working on another computer and nothing works. Aperture just keeps creating the same **** BLACK jpegs. I can see/open the original jpg in preview/photoshop, etc and it is ok. Dunno where to go from here.....

Lion with the latest Aperture.
Yes, the original images (JPGs taken on the camera) are ok. I can see them tucked away in my Apeture Library folder. When i delete and regenerate previews and thumbnails Aperture creates jpgs that are black. I tried using the same library on a different computer by booting my laptop into target disk mode and got the same result.
I finally gave up trying to fix this, and instead deleted all those photos. I have a 'master' library i import all my photos into before moving them to my 'live' library (that doesn't include the RAWs) so i just reimported for that library.

Thumbnails and Previews have a green tinge

The thumbnails and previews in my library have suddenly developed a green tinge.
I have tried Update Previews, Generate Thumbnails, and Generate Previews with no success. I have also used Repair database and Rebuild database, again with no positive result.
I am at a loss to know what to do next.
Jerry

I have a similar issue, but it doesn't seem to affect all thumbnails.
Thumbnails have thos unprocessed raw look (bluish, greenish tint):
But they look fine once you open the real pictiure:
What could possibly cause this problem? I have re-generated prebviews and thumbnails but can't seem to solve the problem.

Bridge jpeg thumbnails and previews get RAW settings

On jpeg files without any RAW setting applied, Bridge still applies RAW settings to the thumbnails and the preview are thus display incorrectly. Opening the file shows the jpeg as it should be, without RAW settings applied.
I have RAW preferences set to apply auto settings to RAW files without any current settings.
I have my RAW settings to open jpegs in RAW *only* when they already have settings. If I set this to disable jpeg support, then the RAW settings are not automatically applied to jpegs without existing settings. aka, Bridge redoes the thumbnails without the auto setting.
While it is correct to apply this to RAW files without settings, jpeg files are already "developed/printed" and should not get additional auto develop settings automatically applied.
My Bridge is 4.0.4.2
Raw is 6.3

Thanks, I did, since it is affected by a RAW preference I figured a double post was acceptable.

Lightroom Slideshow black thumbnail

Greetings -
I have been searching the forums to see if anyone else has posted this concern.
I have created a slideshow using LR5 - even added music - works great! ... However, after upload it creates a black thumbnail and people perceive this as an issue with the video.
Is there a way to alter the slideshow not to do this?
Jae

How many images for the slideshow. How long before selecting slideshow and hitting play is? G4 is real slow for LR, and it takes time for the Slideshow to render. Have you first rendered standard previews?
Also, just to be sure, check your monitor profile.

Thumbnail and image issues iPhoto 'o8 & Leopard

I installed iLife '08 a few weeks ago and then installed Leopard on the day it was released. I have recently imported a few high-res images (adjusted in Photoshop CS2) and some of them are listed in my iPhoto library but I can not see the photos. I simply get a black thumbnail and when I double click the image it does not appear in the separate window. I can see the image when I go to make a slideshow, but I can see the image when viewing it in the folder or event. Any idea what the issues are?
Thanks,
Mark

Back Up and try rebuild the library: hold down the apple and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.

Imported and created "optimized media" but thumbnails and video is missing!!

Hi guys,
My i7 MacBook Pro just spent the last 12 hours importing a selection of h.264 .mov's from my Canon DSLR. I had selected "creat optimized media" to convert it all into ProRes at the start like I have for my other projects in FCPX. But this time, once it had completed, only a couple of the clips have thumbnails/ play video when scrubbed over, and the vast majority of the clips have black thumbnails and only play audio. I tried restarting FCPX without any luck... any thoughts on what's going on? If I have to spend another 12 hours doing it over again, I'm going to have one unhappy client.
Between random bugs like this, freezes, crashes and the lack of ProRes LT (I'm bloating all my Canon video files by converting them into regular ProRes and hogging up hard drive space at an alarming rate), FCPX is really starting to get on my nerves. I've been really patient with the software and wanted to like it so much - I even gave it a positive review on the App Store, but Adobe Premiere is looking better and better every day.
Thanks in advance for any help guys.

Just out of curiosity- what happens when you click 'Create optimized media' off in preferences? Also- are the original clips still visible and working on your hard drive- i.e. the H.264 clips from the camera?

THUMBNAILS and PREVIEW Pane

I have "Windows 7 Home Premium 64bit. I had set up my Windows system to view many formats over the last couple of years and consequently was able to view image icons and image previews for psd files in Windows Explorer without problem. At some point that all changed---
Now some (not all!) psd files have a generic icon and no preview in the Explorer Preview pane, while others have an image icon and an image preview in the Preview pane---sometimes within the very same folder!
I usually use my Elements 1.0, but some files are from my Elements 8 (which I only used briefly because it was extremely difficult to see because of the dark gray/light gray/black interface of both of the two options). Have not found the viewing problem to be connected to version (as far as I can see).
Any help would be appreciated!
Janet

>No, the PSE10 interface can only be the default (excellent, as far as I'm concerned ) dark interface.
I find the white text on black bkgrnd fine (although harder on the eyes because not as crisp as black text on light gray bkgrnd.). What completely screws it up for me, is where they have black on dark gray—sometimes it completely blends in. Examples are all the little black triangles on drop-down and pop-up menus, and the outlines of buttons. I can see it would be fine if you already know what and where things are, but I found things you could click on from reading posts that were completely invisible on my screen! I guess it’s time to do a new gamma setting and other monitor calibrations..:-)... I also just discovered that even though my monitor has two settings (one for text, and a brighter one for graphics), the screen apparently dims after being on for a long time (I have it set on high contrast for graphics). If I change it to text and then back to graphics, the ‘new’ graphics setting is much brighter than it was---and those triangles and buttons show up much better! Also ambient lighting makes a big difference. Those black-on-dark-gray bits show up better in a totally black room—but I am a lover of daylight...:-)....I just find that if I then open up PSE 1, everything looks so clean and clear, and with no strain......
>if the PSD files have at least one saved selection, then the current version of Sage Thumbs will not display the correct version of the image...
I was surprised to find that duplicating, flattening, and saving as a tif showed ONLY the saved selection as the thumbnail (as for the psd file)! I thought flattening would merge everything together into a regular tiff....

I like and use Top Sites but it has become unsuable with this constant blacking out and reloading the thumbnails. My MBP has not seen a problem at all.
I have been searching every other day for over a month trying to find a fix in Windows Safari with no joy. I want to resolve, not switch browsers. Please offer up a solution that only refreshes the Top Site thumbnails once a day or as some controlable interval. Started about two versions ago, now on ver 5.1.5. Windows 7 64bit.
Safari 5.1.5 for Win64 bit, Windows 7!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I think I solved the wifi connection problem, just by switching off completely the router! sounds trivial, but in this case it worked!!!
the funny behaviour of the trackpad/cursor still persists. any suggestion???
thanks again
