Constraining file-sizes in iPhoto 6

Is it possible to export a file under iPhoto 6 such that it is constrained to a specific file-size? Such as, if I import a 1 MB file and I want to export a copy that is only 500K in size, does iPhoto have this ability? I see where I can constrain the dimensions of the image, but not the size of the file itself.
Any ideas?

HI Chris,
If you have no other image editing software, you can try this on PREVIEW.
Open images in PREVIEW and use the SAVE AS option > you'll see a dialog box, use jpg format, and you will also see a "Quality" slide, move more to left to make file smaller... and save to desktop with a NEW NAME. You will need to practice to get the correct file size you desire. After saving as, image will auto open again in PREVIEW, use the 'Get Info' for final file size, you can determine how much more or less you need...
This is you only option if you need orginal resolution size but smaller file size and you do not have additional image edting software... practice makes perfect...:-)

Btach reduce file size within iPhoto interface

Fellow iPhotorers
Is it possible to bulk or batch reduce file size within iPhoto - i.e. without having to export then re-import the pics THEN delete the originals?
For example - if I have shot a bunch of pics at high res which I decide or worth keeping as small (low KB) jpegs and not 3MB camera originals.
Cheers
Russell

Russell:
Welcome to the Apple Discussions. Depends on what you mean by resize. Do you want to reduce the pixel dimensions, say from 2272 1704 to 800 x 600 keeping the same ratio of dimensions, and, thus, reduce the file size? Or do you want to keep the original pixel dimensions and reduce the file size, which requires a reduction in quality thru greater compression?

Reducing file size in iphoto

I needed to free up disc space (I have over 6000 photos stored in iphoto). I couldn't find a solution in this forum, but have hit on a way that works.
1. Move photos to a CD to preserve original file size. 2. Export photos at reduced file size to a folder on the desk top. 3. Trash original photos. 4. Import reduced size photos. 5. Trash folder.
Reduced size photos are fine for viewing and 4x6 prints. Larger prints can be made from the CD.
Perhaps there's an easier way, but this works.

File -> Export
Note the Jpeg Quality setting. That has the most impact on file size.

How do I reduce file size of iPhoto library that's had photos deleted?

I created a calendar in my iPhoto library (which contains thousands of photos). I want to save the calendar now as a separate library with just the calendar in it. I duplicated my iPhoto library and deleted everything except for the dozen or so images used in the calendar. However my iPhoto library is still over 10GB! I've checked the trash is empty and I've rebuilt the database. Is there anything I can do to reduce the file size of the library?
Thanks

Empty the system trash. If that doesn't help:
Go to your Pictures Folder and find the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed.
Is there an iPod Photo Cache? You can delete that too...

Export constrain file size

The lab my client uses doesn't like to handle jpegs larger than about 2MB. OK, that's their rule and I have to make it work.
In PhotoShop, when I converted to jpeg I could see how large a file it was going to produce. In LightRoom I don't know how to do that. I can choose a quality, which isn't measured in anything. And I can enter a dpi, which shouldn't make any difference if the pixel count is unchanged. There's no way to sort by size. So I guess and export them all, then check the sizes and go back again and re-export the files that are too large. Very Clumsy.
Can anyone advise me how to get these Canon 5D files to convert to jpegs at around 2MB?
-wick

Through trial and error (no help from LightRoom), I decided to contrain the file size to within a 2K by 2K pixel rectangle. This gives me roughly the right file size. thanks to all for your suggestions. In the end, of course, I either have to downsize the image or raise the compression to around 60 (as Ian suggested). In the end, assuming a print size no larger than 8 x 10, do you think the better solution is to downsize or upcompress?
-wick
PS: Has anyone else come across the bug mentioned in my second post, where exporting the same file over and over leads to the wrong file getting exported? Maybe LightRoom just got bored?

Am i able to adjust the file size with iPhoto?

or the pixel size?

You can change the file size by exporting (and reimporting) with smaller pixel dimensions. You could also change the preference so a double click opens in an external editing program such as Graphic-Converter or Photoshop with which you can reduce file size.
If you are running out of space I'd recommend getting an external drive and putting stuff on that.

Aperture File Size vs iPhoto

Hi folks, this issue has probably been handled before but I searched and couldn't find it in the first few pages.
I import all my pictures with iPhoto. Then when I export the pictures I wanna fix and import them into Aperture. The problem is, I noticed that a file that is 1.8mb in iPhoto ends up as about double the size in Aperture. Is there any reason for this?
And what I mean is, when I choose "export version" the file coming out of Aperture is about twice as big.
Any help would be appreciated.

Can anyone give me advice or point me in the right direction? I shoot RAW and the files are approx 15mb- when I export them to jpeg original size they are only about 2mb. I am worried as I am told I need at least 4-5 mb for a quality 8X10 print?
Any ideas on how to make the mb size (jpeg) larger? I have the quality at 12, the dpi at 300 and the setting for jpeg original size.
Thanks so much,

Can you sort images by file size?

Is there any way to sort pictures by file size in iPhoto '08? I couldn't figure it out, but maybe I'm just an idiot. Thanks in advance for your help.

No - there is no way to sort by size
the only current sort options in iPhoto are under view menu ==> sort photo ==> by date, by keyword, by rating, by title, manually (only works in Photos display mode with event titles off as of now)
Suggestions for new features o iPhoto menu ==> Provide iPhoto Feedback
You can see the sizes by right clicking on the iPhoto library in the Pictures folder and selecting show package contents -- you should not modify the contents - this might cause iPhoto to get confused and cause problems uncluding losing photos (or at least not being able to see them in iPhoto)

File size changes after importing photos

Quick question here. I've been using iphoto (now using iphoto 8)for a couple years and just noticed that after importing photos (I use a variety of original formats, usually jpeg or raw) the file size in iphoto is a lot smaller than the original (roughly half). First of all, why is this? Is there any way for iphoto to retain the original size? If I try copying a photo out of iphoto, say onto my desktop, the file size remains the same as it was in iphoto. In other words, it doesn't revert back to the original.
Any idea as to why it would do this?
Some help would be much appreciated.

Welcome to the Apple Discussions. When a raw file is imported iPhoto creates a jpg version so if you're looking at that and comparing to the size of the raw file, yes it will be smaller.
If you edit a photo the resulting file will be slightly smaller since there will be one level of jpeg compression added to the file. All subsequent edits will not cause any more compression because the edit instructions are saved in the database file and applied to the file for viewing, printing and exporting. That's why iPhoto calls it nondestructive editing.
If the photo is portrait oriented and comes from a camera which has the auto-rotate feature iPhoto will create a rotated version and that will contain some jpeg compression.
Dragging the photo to the desktop will bring the edited version which will be smaller. To get the original file export using the Format=Original setting as Larry has already pointed out.
If you're worried about image quality unless you will be printing a very large photo you'll be hard pressed to see any degradation in the image.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier versions) 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 created an Automator workflow application (requires Tiger or later), 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. There are versions that are compatible with iPhoto 5, 6, 7 and 8 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
NOTE: iPhoto 8's new option in it's rebuild library window, "Rebuild the iPhoto Library Database from automatic backup" may make this tip obsolete. We'll know when users have occasion to use it and see if that's the case.

Pixel dimensions / file size

I am trying to publish a photo to a website with specific limits for pictures. How can I adjust pixel dimensions and file size using iphoto?

Hi wrigjef: Try this: iPhoto open, select the picture(s) you wish to work with, from the "File" menu, select Export. The resultant dialog box will give you several options for pixel dimension, file size etc. After files have been saved to the specified location they can be then up-loaded to the website.
Hope this helps

How can I find the file size of an image within an iPhoto event or album?

In order to see the file size of any particular photo, I've been dragging a copy onto my desktop and using "get info." Is there a better way?
I'm using 10.7.4 and iPhoto 11 v 9.3.2

1. That's only getting the file size of the Preview.
2. Click on a photo to select it. Then click on the info button. You can get the dimensions and the file size in the top of the pane
Note that the final size of any image will depend on the export settings you choose.

In iphoto, how do i save a photo after editing, in the same or higher file size, it's saves in a lower size

in iphoto, how do i save a photo after editing, in the same or higher file size, it's saves in a lower size

It's rather more complicated that this.
iPhoto is a lossless editor. You don't lose any quality on your shot in iPhoto.
The file size you see reported is the size of your iPhoto Preview: this is what gets used if you access the data via a media browser. It's a "good-enough-for-most-uses" version of the shot. Email it, upload to websites, use it in Presentation, Word processing file etc
If you want to set the quality yourself then Export the photo using the File -> Export command.
You can choose to export to Jpeg, Tiff or png. Tiff is lossless but the file sizes are up to 10 times larger. Jpeg allows you to choose different qualities: High, Medium or low. The difference is the amount of compression involved. High quality means very little compression. It's not unusual for photos exported at this setting to have a larger file size than the original.
Which setting you choose depends on the use you intend. Further editing, printing then high is important. Sending to Facebook? Well low will do just fine there as they're going to trash the file anyway.
But the key point: the file size only becomes an issue when you export.

I have a few hundred duplicates in my iPhoto library, but the file sizes are different. So one is 1.3mb and one is 567kb. I want to delete the smaller ones, but short of comparing each duplicate, is there a way to do this?

I have a few hundred duplicates in my iPhoto library, but the file sizes are different. So one is 1.3mb and one is 567kb. I want to delete the smaller ones, but short of comparing each duplicate, is there a way to do this? I've been looking at Duplicate Annhilator but I don't think it can do it.
Thanks!

I just ran a test with iPhoto Library Manager, Duplicate Annihilator, iPhoto Duplicate Cleaner, Duplifinder and Photodedupo. I imported a folder of 5 photos into a test library 3 times, allowing iPhoto to import duplicates. I then ran the 5 photos thru resizer to reduce their jpeg compression but all other aspects of the file the same.
None of the duplicate removal apps found set that was reduced in the file resizer. That's probably due to the fact that the file creation date was being used as a criteria and the resized photo would have a different file creation date even though the Image Capture date was the same.
They all found the 3 regular duplicates and some of them would mark two and leave the 3rd unmarked. iPhoto Duplicate Cleaner can sort the found duplicates by file size but if the file was edited to get the reduced file size it might not be found as it would have a different file creation/modification date.
iPhoto Library Manage was able to find all duplicates and mark them as such if the file names were the same the the filename option was selected. Otherwise it also missed the modified, resized version. It allowed one to select the one photo to save before going to work on the library.
So if a photo has been reduced in image quality or pixel size it will not be considered a duplicate.

When making a photo book, my iPhoto freezes during uploading the book to the store after assembly. I have attempted this 4 times now and I don't know what to do! I know the file size is massive due quantity of large images. How can I get past this?

When making a photo book, my iPhoto freezes during uploading the book to the storey. I have attempted this 4 times now and I don't know what to do! I know the file size is massive due quantity of large image files, but I don't want to reduce the image file size and compromise quality in the book. How can I get past this?
My macbook air is os x 10.9, using iPhoto 11 9.5 (902.7).

Try Old Toad's solution here: See Re: iphoto : upload impossible to print a book
Try to boot into Safe Mode and order this way, or sign into a different user account and try to order as a different user.

Is it best to upload HD movies from a camcorder to iMovie or iPhoto. iMovie gives the option for very large file sizes - presumably it is best to use this file size because the HD movie is then at its best quality?

Is it best to upload hd movie to iPhoto or iMovie? iMovie seems to store the movie in much larger files - presumably this is preferable as a larger file is better quality?

Generally it is if you're comparing identical compressors & resolutions but there's something else happening here. If you're worried about quality degrading; check the original file details on the camera (or card) either with Get Info or by opening in QuickTime and showing info. You should find the iPhoto version (reveal in a Finder) is a straight copy. You can't really increase image quality of a movie (barring a few tricks) by increasing file size but Apple editing products create a more "scrub-able" intermediate file which is quite large.
Good luck and happy editing.
