Will iPhoto recognize duplicate image files on import?

I was wondering if when importing image files into iPhoto 09 there are 2 files with the same name and EXIF data will iPhoto not import the dupe or at least warn that there is a file by the same name already in the catalog?

It will warn you and ask you what you want to do.

When I try to import video, Lightroom-4 will not recognize the video files. How do I fix that?

Lightroom 4 will not recognize the video files. It will only import the photo files. How do I import the video files?

You might provide some additional information, such as what types of videos, from what cameras, and what version of LR4 you are using.

Frustration - Iphoto corrupting image files during import (?)

To begin with, I'm a recent convert from Windows to the Mac. I'm running a mac mini at home, and a Macbook with Boot Camp at work (in addition to my desktop pc). All of my software is up to date...
I take alot of pictures with my digital camera (canon powershot). Saturday I took about 300 pictures, took the SD card out of the camera, put it into my Sandisk card reader, imported the pictures into iphoto and everything worked great. I chose to not delete the pictures after the import as I wanted to bring the card into work and upload the pictures on my pc.
The next day (Sunday) I took another 70 or so pictures. I was able to view all of the pictures on my camera that I had taken over the past two days.
I go to do an import , taking the exact same procedures that I took on Saturday (and that I always do). The first thing it does is identifies that there are duplicate pictures. I choose the option of "don't import duplicates" and apply this to all of the other duplicate pictures.
At the end of the import, I got an error message saying that some of the files were corrupt. Now, there were pictures from Saturday that were still on there (and readable/viewable). However, every picture that I took on Sunday was "unreadable" and did not show up in iphoto. I put the card back into the camera, and now I can't view the pictures (they show as "corrupted data".
I then pulled the SD card details up in Finder, and the "corrupt" files still show sizes of 2.4mb to 2.8mb, consistant with the good pictures. It shows the file's "Kind" as JPG Image... I double clicked on them and Preview comes up saying something to the extent that the file is corrupt,
I've taken the Sandisk card reader, plugged it into my Macbook (using iphoto in osx) and was able to view one or two of the pictures from Sunday.
Once I got to work this morning, I plugged the sd card into my Windows machine and it too says the files are corrupt. It shows them being on the card, it shows the file sizes, but I can't open the pictures in anything...
If this was a one time deal, I'd be thinking it may be something I've done to cause the problem. However, this is the third instance I've "lost" all of my photos because of them becoming corrupt during an import into iphoto. There definately appears to be a pattern.
I have somewhere around 8,000 pictures inside iphoto that I've taken and had no problems with. I mention this to illustrate that I'm not doing anything differently than I've done before. I have another 14,000 on my old Dell that I need to move over, but I'm questioning if I should do that now.
Does anyone have any ideas on what the problem might be? Is anyone else experiencing (present or past tense) this problem? Where I'm new to the mac, I understand that I might be doing something wrong. However, I've imported photos to the software (what seems like) hundreds of times, the same way each time. This makes me want to rule out user error...
One other question, I'm saving the "corrupt files" with the hope that there's a software program which will "fix" the files. Do you happen to know of such a piece of software? I'm hoping that I can get them fixed at some point.
Where I'm taking pictures of my kids, its extremely frustrating to find out that the pictures (memories) I was hoping to make prints of are now "gone". Its almost like rolling the dice when doing a photo import any more. Most all of the time it takes, but every now and then the pics are lost...
I'm hoping to identify the problem (either user error, procedure or software issue) and fix it as I really like the mac.
Any help/suggestions you might have for me would greatly be appreciated!

Welcome to the Apple Discussions.
First: the corrupt files: download Graphic Coverter, a shareware which is often successful where other software isn't. But first, if the Mac will let you, copy the files off the card to the Mac.
I'm in this board a while now, and I can't recall an issue of iPhoto corrupting images on import. After all, it's just a simple file copy, at heart. I would be more inclined to suspect the card. DO you have more than one? Does the problem also occur with the other cards?
Try use Image Capture to download the pics to the Mac first, then import them, see does that help. Image Capture is in your Applications folder.

Import does not recognize old image files that have no extension

Just discovered that the import facility does not see (or accept) old Mac image files that have no extension -- even if these files have a Mac "kind" that is an image such as "Adobe Photoshop file".
You can manually add an extension to the file (and respond to an "are you sure?" dialog). Then the file will be seen and accepted.
This is extremely dangerous (and painful to manually correct) since you think you are seeing all images in the import box, but you are not.
In fact, I deleted huge image directories after having satisfactorally (I thought) imported them into Aperture many months ago. Most of the old extension-less files had been updated and did have extensions in later versions. However, I missed one important image and looked everywhere for it.
By a miracle I had a backup of my image directories on a Power Book that I am retiring and finally noticed that the missing image was there just before deleting that directory too! I then figured out why this image (and many others) had not been imported. So, now I am going through manually and adding extensions.
Does anyone know a better way -- to get Aperture to recognize extension-less images? If not, this needs to fixed in the next version as it is a disaster waiting to happen.

Well there's an idea...probably would need to go into Bridge <g> to do that most efficiently .. or Automator.
It turns out that I already had added extension to most (but not all) images in my main image directory and so they got into Aperture alright. I just have to go through all the images in the backup I just found (where many did not get extensions) to find the ones that Aperture missed. So far, there have been just a couple more...
The real problem is that Aperture should not be missing these, even if they are archaic. At the very least, Aperture's import should give a warning that there are files in a folder that it is not going to import AND is not even showing. Otherwise this is a serious gotcha!

How does iPhoto recognize duplicates?

I recently imported a folder (including several sub-folders) of photos into iPhoto. It asked me if I wanted to import duplicates, and showed me a side-by-side of the two pictures in question. Since they we're clearly the same, I said no. After doing that for several photos, I finally said no for all duplicates, and the import rapidly completed.
But then I got to thinking. How does iPhoto actually recognize a duplicate? Is it solely by the external characteristics (name, date, size), or does it have a method to actually analyize the content of the two photos to see if one is actually a copy of the other? I really hope it is not just by name, as I have a number of photos that have the same name but complelely different topics.

Duplicate files are detected by comparing file name and the EXIF Capture Date.
There is one photo duplicate detection app that detects duplicate images by comparing the bit map or histogram of the image.
PhotoSweeper - $9.95 - This app can search by comparing the image's bitmaps or histograms thus finding duplicates with different file names and dates.

Make iphoto NOT duplicate images?

Hi,
I like almost everything about iPhoto, except that it duplicates your images when you import them into your library (at least that's my understanding of what happens). With thousands of images (most of which are about 2 Mb each), that can get to be a very large chunk of any hard drive (internal or external). I understand the reasoning behind the duplication (lossy jpg files), but is there a way to turn that feature OFF in iPhoto? I simply want to organize and batch rename photos when they're downloaded from my camera. I can handle file duplication myself, when I edit photos in Photoshop.
If iPhoto can't turn duplication off, can anyone recommend other software that's good at organizing and batch renaming? I don't want anything fancy (no slide shows, no web posting, no photo albums); just reliability.
Thanks!
Barbara

iPhoto does not duplicate your images when you import them - unless you already have them on the HD. (and if so, why not delete those copies?).
When you import a photo iPhoto creates a tiny thumbnail of the photo for display in the iPhoto Window.
If you edit a photo iPhoto preserves the Original - and now you have a modifed and an original - different versions of the pic, not duplicates.
And no, there is no way to stop iPhoto doing this.
You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.
I simply want to organize and batch rename photos when they're downloaded from my camera.
Then why do you need another app at all?
Use Image Capture to move the files from your camera to the Finder. Set up a basic folder structure for yourself. As for batch renaming, there are any number of renaming utilities, myself I use Name Mangler.
What else do you need? It's the Finder, how much more reliable can you get?

Why can't iPhoto recognize duplicate pictures?

My dad recently reinstalled OSX on his computer. He regularly backs up his photos on discs and hard drives, so there's a lot of overlap. While importing the files back into iPhoto 6, duplicates of two, three, and sometimes four keep popping up. Why can't iPhoto not import duplicates like the camera import? We can't possibly sort through 10,000 photos manually!

Check out
Duplicate Annihilator
You might also like to research how to back up and restore iPhoto to avoid the problem occurring in the first place. For instance, if you've backed up the entire iPhoto Library Folder, then all you need to do is copy it back to the Pictures Folder and launch iPhoto - there's no importing. Something similar is the case if you've backed up using the Share -> Burn command. The specifics will vary depending on how you back up.

Mac osx 10.6 will not recognize disk image of HP driver download

Wanted to scan from my HP officejet pro 8600 and send to my Mac desktop. Message said that I had to download a driver first, so I did, but now the computer will not recognize the disk imag. I don't know what to do so that the Mac will recognize the disk and allow me to install the download.

Hi @dabeck
I would like to help you install the software for your 8600 onto your Mac. Since the Mac is unable to recognize the disk image file, I would first suggest we repair the disk permissions. Please use the steps below to troubleshoot the issue;
Repair Disk Permissions
On the Dock, click Applications, and then click Utilities.
Double-click Disk Utility.
Highlight your hard drive/partition on the left (by default this is "Macintosh HD").
Click the Repair Disk Permissions button at the bottom of the window.
Once the repair is complete, restart the computer.
Restart the printer. Now you can download and install the printer software and install it. > Officejet-Pro-8600_v12.23.0.dmg
Please let me know the outcome of these efforts. I hope to see this resolved quickly for you.
Please click the Thumbs up icon below to thank me for responding.

Does iPhoto change a RAW file upon import or export?

Hi! New Mac user here. Trying to get my workflows and backups going.
I created an iPhoto library from multiple sources: migration from PC, folders from backup HD, new photos from iPhone and camera memory card.
So I have one consolidated library that is almost 300Gb but I want to go through and remove and archive many of these, leaving only a much smaller working library with the archive copies of some originals stored somewhere else. These archive copies will not be referenced files, my plan is to export them from iPhoto, back them up to an external HD, and then delete them from the iPhoto library. If I ever decided to look at them again, I would import them from the archive HD.
Ideally, I should have imported all the files to my iMac desktop and then imported only what I wanted into iPhoto, but because everything is now consolidated (and the photos from the iPhone and camera memory card are erased), I don't want to wipe out my iPhoto library and start over. So I'm starting with this huge managed library and want to export a good part of it to what I will call "the archive" to cull it down.
My questions: Upon import, did iPhoto change the RAW master files, or will those be the same when I export them (assuming I made no edits)? Did iPhoto change the JPEGs or will those also be the same when I export them?
How do I export the files I want to save to the archive before deleting them from the iPhoto library?
Alternatively, I think I will use Aperture going forward for editing. Should I use that instead for trying to export these files?
Thank you for any assistance you can provide.
LCA
iMac 4 GB, 2.7 GHz, Intel Core i5
OS X 10.7.4
iPhoto 9.3.1
Aperture 3.3.1

File -> Export and in the resulting dialogue set the Kind to Original
That will export a byte by byte copy of the file you imported, unchanged in any way.
Can I suggest another way of working. Why not have two Libraries? An archive and a working one?
The principle advantage is that you won't have to import pics to review them again later, just open the other library.
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
Now you have two full versions of the Library.
3. On the Internal library, trash the Events you don't want there
Now you have a full copy of the Library on the External and a smaller subset on the Internal
Some Notes:
As a general rule: when deleting photos do them in batches of about 100 at a time. iPhoto can baulk at trashing large numbers at one go.
You can choose which Library to open: Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
You can keep the Library on the external updated with new imports using iPhoto Library Manager

Does iTunes duplicate mp3 files I import, thus doubling space used on mac?

Hello.
May be a silly question, but here goes:
When I import mp3's onto my mac (from my old computer), i put them all into one folder..
when i double click to play, they automatically play through itunes.. now i've noticed that itunes NOW ALSO creates a duplicate folder/file of those tunes that I have now played through iTunes, (in "user" > Music > iTunes > iTunes Music)...
does this mean that there are now 2 copies of the mp3 on my hardrive, therefore taking up space?? I'm not entirely sure - but would not be happy if every song actually takes up twice the amount of space...
Any help??
Thanks everyone!
Johnny

I'm having a similar problem. Just installed iTunes, first iPod product, and my file usage has dwindled by the size of the music files. They've all been doubled, it looks like. Where is this located, and how can I be sure not to move/delete the wrong ones?
Or, where is the setting to stop this, and if I change the setting do I need to re-install iTunes to get rid of the wasted file space?
Thanks.

Newly installed CS2 will not recognize raw images

I have installed my Photoshop CS2 on my new computer. It will not recognize my raw images. I get a message that says "could not complete your request because it is not the right kind of document". I uninstalled the program and reinstalled it again but I am still getting the same message. I have also registered it with my serial number, but every time I get into the program I get a prompt telling me I need to register.

Many events and photos are missing from my iphoto. I have time machine and would like to restore without creating duplicates. The issue is although my photos are presently blank time machine/iphoto does see the file so importing them will create duplicat

For some unknown reason, events and photos in my Iphoto are appearing blank. The photos have a title / placeholder but no picture. I use time machine and have back ups, my goal is to restore the photos without creating duplicates. Unfortunately iphoto sees the blank photos as if the picture exists? Help

If you want to use your back up you need to restore then entire Library from Time Machine, and then replace the damaged Library with it.

"unsupported image file" when importing RAW images from Olympus E-PL1

When I try to import images save in RAW format on the camera, the images import but they can't be displayed (all I get is a warning triangle with the words "unsupported image format" below it, though in the import preview the images are displayed properly.
EDIT: just noticed that the E-PL1 isn't listed as being supported, just the E-P1 & 2

Apple have just included RAW support for the Olympus E-PL1 with the Digital Camera Raw Compatibility Update 3.3 - iPhoto can now import RAW files from the E-PL1.

Iphoto export makes image files disappear

I export 200 Jpg and mp4 files from iphoto to a network disk folder. After export, finder only shows the 20 mp4 files. When I try to export one or more of the jpg files a second time, I'm told the files already exist. I just want to make sure my files are safe and can be accessed by other computers and photo software.

from iphoto to a network disk folder.
Try export to a Folder on the Desktop and then drag that to your Network Disk. I'm pretty sure this issue is caused by the format of your NAS.

Won't recognize ISO image file

I'm trying to burn a Ubuntu image on a disk. After I use disk utility and burn the disk, it ejects like normal. Then, when I put the disk into my drive, it doesn't recognize the format. Any suggestions?

I had the same problem with the ISO of Ubuntu server 64 bit 12.04.2 Precise Pangolin.
Once burned it doesn't recognize the disk. But the CD works fine anyway. I used it to install the OS on virtual machines and PCs as well.
