IPhoto DB file size discrepancy

I had my macbook pro stolen, but a week before I backed up my iPhoto DB 15.7GB file using Finder to copy/paste the file to an external drive. I copied the backed up iPhoto DB file to my new Macbook Air, but now iPhoto is missing a large amount of pictures. When I launch iPhoto now, it says I have 923x pictures using 4.3GB. I am lost as to how I can recover the remaining 11.4GB and why they're not being displayed. What's interesting is that I used iPhoto Library Manager Rebuild option and it rebuilt my DB to a new file and that DB is only 5.04GB. This makes more sense and proves I'm missing 11GB+ of photos. Any assistance and guidance is greatly appreciated!

Depress teh option key and launch iPhoto - use the select library option to select the library on the EHD and see if iPhoto will open it
You can go to the EHD and reight click on the iPhoto library there and show package contents - are the photos in the masters folder (look - do NOT change anything) - if they are not then you need to have another source for them
For the future copy and paste is NOT a good way to work with the iPhoto library - it is best to drag it to the new location to be sure that an exact copy is made

Incredibly strange file size discrepancy only appears in image files (jpg, gif, png)!

I'm creating a bunch of banners for google ads, yahoo ads, ...etc in Photoshop on my Mac OS!
The .gif files of these banners appear to TRIPLE in size when on the MAC (>150KB), but when transferred to windows; the real file size shows correctly! (<50KB)
It is not a result of the base2 vs base10 discrepancy since the difference in size is simply too big, and it only happens with files created on Photoshop on my Mac.
The reason I know that windows is showing the correct size while my Mac OS is displaying the wrong size, is that the file gets approved by google and yahoo ads, even though Mac OS shows that it surpasses the size limit (50KB) three times over!
This isn't an isolated incident either, all image files created in Photoshop on the MAC continue this weird behaviour! However, files downloaded from the net appear to be consistent on both operating systems!
One example is the attached screenshot:
Explanation, please??

Geez, sorry I offended you Mr. Jobs (incarnate)!
You came in here with a three ton chip on your shoulders. Did you really expect sunshine and puppies in return?
No, I expected useful help, and I got it from Jeffrey Jones. Thanks again Jeffrey!
I mean, when you move or upload it, it loses this data association anyways!
To a drive which doesn't support Apple's AB tree structure (NTFS, FAT, FAT32, exFAT), yes. To another HFS+ drive, no.
What about uploading the file to the cloud?? Does it lose this association or not?? And does anyone really care about the data in the Resource fork?
This "Resource Fork" means nothing to the file owner, only to the OS and the Drive. Therefore, it shouldn't be added to the total. Period. Because its not part of the file, its part of Apple's tree structure! This is really a simple concept, not sure why you are bending over backwords to defend a clearly stupid oversight from apple!
There's no reason to force me to use the command line to get the real file size of a GIF! There's just no excuse for that!
If an OS is saying it is fetching file size information for a single file, it should do exactly that! Not add hidden Resource Forks that are part of the OS's internal workings
OS X is fetching the file size. It's file size, not the way a different OS would report it.
There is no such thing as it's file size. A file size is a file size, accross all platforms, on the cloud, wherever!
A GIF file should have the same file size whether its on windows, linux, unix, darwin, freeBSD, or anything else. The only time its weight should vary is in outer space!
That is why I'm surprised that they are breaking simple UI Design rules.
The User Interface has nothing to do with the file structure of a drive.
I don't care about the structure of the drive!! Neither should you, neither should the average user!
A good UI should NOT concern the user with this! The average user doesn't care about these Resource Forks, and will never try to view them, therefore, there is no logical reason to add up their file sizes to the total size of each file, and then to make things worse, hide that fact! That only creates confusion, and it makes it so much harder for a designer like myself to view the REAL file sizes of my image files! Now, whenever I'm on my MAC, I will have to run command line scripts to be able to see if my GIF files (that I work on EVERYDAY) meet the file size quota, because Mac OS adds up hidden files that I have no use for and gives me the WRONG file size!
Let's say this again: when you select a file and click get info, you should get the info for the file you selcted. Nothing more, nothing less! I don't care if the file structure creates an entire colony of hidden files, they should be completely hidden to me, and if not, the Get Info dialog box should at least give me two sizes, one is the REAL file size, and the other is the added up file size for the Resource Fork as well (although I can't think of any good reason why it should add up the Resource Fork size anyways)!
do you think it is at all logical, that when you select 300 or so files, and click Get Info, that it open 300 windows at once each showing separate information for each file? Or does it make a lot more sense, intuitively, to get the total tally of all the files selected added up, without having to hold down shortcut keys when clicking them to do so?
Yes, it is logical because that's what you, the user, told the OS to do. You wanted the Get Info data on 300 individual items. I don't know about you, but I avoid the menu bar as much as possible (your reference to avoiding shortcut keys). Command+I will always give you singular Get Info dialogue boxes.
No, that's not what I told the OS to do. I selected 300 files cumulatively, therefore, I should get the cumulative info for all the selected files. That's just common sense. Every other OS seems to get this!
And I'm hard pressed to find anyone who has found a use for having 300 get info boxes open at the same time. Therefore, that shouldn't be the default.
Will you start defending apple's decision to stick with the one button mouse for all these years depriving us from the all important context menu as well?? There was absolutely no good reason to do that, just as there is absolutely no good reason to do this!

Compressing photo size in iphoto - want file size small but pic big? how?

Hello
I hope this is the right section for this post.
I am building a website and I want photos on it, I am building it in iWeb.
in iPhoto is there any way of making my photos a smaller file size?
I have cropped them a bit, but some are still about 400kb.
I want my site to load quickly.
I want a gallery page with thumbnails to click on to enlarge them, but on my home page I want 1 big picture. What is compression and can i do it in iPhoto? Can I still have a picture the same size (to look at) but the file size is smaller. I have heard photos should be about 30-70kb and mine are 400kb jpegs!?
Macbook Mac OS X (10.4.8) using iphoto and iweb, not hosting on .mac

Betsy
I believe that iWeb optimises the pics when you publish the site, but you could confirm that on the iWeb forum.
If you want to reduce the size of pics using iPhoto, you do that on export: Select the pics you want and go File -> Export. Use the dialogue to specify the size of the pics you require and export them to a folder on the desktop.

File Size Discrepancy Between Photoshop & the Finder

I'm trying to be as brief as I can, so here goes. The specific application (PS) is irrelevant, I think. This is about why an app shows one file size & the Finder shows a different file size. In this case, it's a huge difference, due to the file being an image.
I imported into PS CS, from a CD, an original image, which the Finder shows as 269.4 MB. The file format is TIFF, and the bit-depth is 16, not 8. The Finder shows it as a "TIFF Document." Now. I did a Save As and edited that as a master image file. So, I have two files: the original and the master.
I substantially cropped (deleted) pixels in the master file. So, at the same 16-bit depth, the master file should be smaller in size than the original. Right? However, the Finder shows the file to be 433.6 MB in size! Photoshop shows the file to be a more realistic 185.8 MB in size. Why is the Finder showing such a huge file size? Why is the Finder storing 247.8 MB more than I need? The Finder shows this file as an "Adobe Photoshop TIFF file," so there has been a change in format. The file is flattened; no layers, etc., are involved.
One clue could be that the Finder is storing the larger file size to accommodate Photoshop. If one multiplies 185.8 MB by 3, the result is close to the 433.6 MB figure. The 3 stands for the three color channels (red, green, blue) of each pixel (data element) in the image.
The original image, however, is stored correctly by the Finder. Photoshop and the Finder agree on the 269.4 MB file size. If the above scenario were true, the Finder would be storing the original file at three times the size as shown in Photoshop. In other words, there would be consistency in what the Finder is doing.
I suppose I could just ignore the discrepancy, but I have hundreds of images to process, and I don't want to have to go into PS every time to get a true reading of file sizes. The Finder should be accurate in doing that.
I may be in the wrong forum re: Photoshop, but here I think I can find some expertise re: the Finder, since the Finder's storing procedures are in question, to my mind. It's definitely an app/OS interface problem, as I see it. Simply, I edit a file downward in data, save it, yet the Finder saves it at a larger size.

...do you think a lot of cloning & healing brush might have added to the file size, even though I cropped the image?
Yes, depending on your History settings. The more you work on an image, the more history it accumulates. The more different states and sanpshots you save in the History palette, the bigger the file gets as you work on it, because you're storing (within the file) complete information about the file's state before and after every individual change you make to it. What I don't recall is whether that all gets saved to the file in a Save As, or whether the history is flushed each time the file is Saved.
I should warn you that I am by NO stretch of the imagination a PS expert. I was still using PS 5.0.2 until last February, when I upgraded to CS2 (knowing it will be years before I have enough hardware horsepower to run CS3). I'm a rank beginner with CS2, and if someone else wants to jump in here and point out that I'm all wrong, it will be no surprise to me. And because I never used CS, I don't know whether what I'm describing in CS2 is even relevant here.

File Size Discrepancy

I hope somebody can help me! I have a Quicktime self-contained movie which in the "Get Info" option says that it's 2.26 GB, but in the Quicktime "Show Movie Info" option it says it's data size is 55MB. Why the discrepancy?
Power Mac G5 Dual 2.3 GHz Mac OS X (10.4.7)

I don't understand. Do you mean the higher figure is it's actual file size?
If I assume both of the above readings were in fact taken using the same file as the source (i.e., you did not use the original source file for the first measurement and a final converted file for the second), then yes, that is exactly what I mean. I don't know how you measure the size of a file, but I take it to be the amount of space required to store the file on a hard drive. Now it is possible that a file can be corrupted and contain many "empty" or "unused" data blocks. So I cannot rule out this possibility here. If you have reason to doubt the "file size," simply try copying it from one hard drive to another and see if both copies require the same amount of space for storage.

Screen Capture File Size Discrepancy

Can someone please explain to me why the screen capture (cmd-shift-4) generates such huge files?
I made a screen capture which was saved to my desktop as picture-1.png. Examining the file's properties showed that the file size was 1.03MB.
Next I opened the file in Photoshop, used Save For Web, and set the file type to PNG-24. This file, which in every way is identical to the original except for file size is only 11kb.
Why is the OSX screen capture larger by a factor of nearly 100?

Just by way of illustration, when I take a PNG screenshot of my 23 inch LCD I get a 4.4 MB file. But only if the desktop picture is all that is showing.
By contrast, a PNG screenshot of the same screen with OSX windows covering the desktop is only 360KB. Why the discrepancy?
PNG compresses using a raster notation that works at its best when continuous identical pixels cover some horizontal stretch. Just like Mac OSX windows. Noncontinuous colored pixels are very hard for PNG to compress, since there are very few identical colors. This is why photographs should be compressed with JPG (which uses a color averaging scheme) and web animations with PNG.
The OSX screenshot format uses 32 bit PNG, which is 16.7 million colors. So if you are reducing the bit depth to 24 bits, that is a huge reduction in filesize. Especially if the 24 bit format converts colors to identical runs, which compress better in PNG. I am talking about color variation you can't even see. That would explain the "factor of nearly 100" you noticed.

Vault (external) file size Versus Aperture Library (internal) file size discrepancy?

Using Aperture 3.3.1 (all my images are Referenced). I created my first vault on an external hard drive. The Vault.apvault file size is 32.8 GB. My Aperture Library.aplibrary file size on my iMac hard drive is 81.6 GB. So I am wondering if I have a full back-up in Vault or not. Seems like a large discrepency in file size. Any thoughts or help would be appreciated.

Do any Images that you don't expect show up when you filter "Photos" using the Rule "File Status" with the argument "Managed"?
If not, then close Aperture and repair your database. Instructions are on the Apple Aperture trouble-shooting page.
Does that make any difference?

IPhoto changing file size to 0 kb after only a few edits

I am uploading approx 5mb sized files directly from my camera into iPhoto. after just a few edits ( rotate, crop, color boost - nothing but presets) the file size is reduced to 0 kb and I cannot access the photo from any other program ( upload to facebook, email, slideshow). I can still see the thumbnail with the edits I made but can only do any thing with it if I revert to original. When it changes back to the original file size as well as the original photo. I am using version 8.1.2

Then that suggests the original Library is corrupt.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

Photoshop file size Discrepancy

Hey Guys.
I have a photoshop file which while editing states what I believe is the flat/layered file sizes down the bottom left of the screen of 116.7M/255.4M.
But when I save the file Finder shows the file size as being 1.53GB.
Is this normal? What am I missing? See below screen grab

The size in Photoshop is pretty accurate.
But it has nothing to do with file size.
Please read the documentation again.
Files are compressed, and different file formats will compress differently, and the amount of compression is very much related to the image content.
That's why Photoshop never displays file sizes except for estimates in the JPEG and the Save For Web dialogs.
The sizes displayed in Photoshop's status bar and info palette are the size of the document in memory, or the flattened size of the image (uncompressed).

Slight file size discrepencies between identical photos?

While looking at the metadata of photos I am working with, I have noticed that identical photos in every single aspect of pertinent metadata (lense, focal, other various exif data) happens to have a slight file size discrepency. For instance, a dscf2001 has a file size of 752kbs and the duplicate dscf2001 has the file size of 732kbs. These photos have not been altered in any manner.
This situation happens with a large portion of my duplicate photos. One photo's file size is slightly bigger or smaller than the other photo that is the identical version in every single aspect minus the slight file size difference. Is this a math situation? If I open with another program will these photos appear as the same file size?
Thanks

They have been copied between drives with different filesystems (iphoto and aperture and old macbook to new macbook). Maybe this is the issue?
How did you transit your images from iPhoto? Did you export them from iPhoto or import the iPhoto library? Have the images you are comparing been imported from iPhoto at the same time, from the same iPhoto versions?
If you compare the original master image files of the images in question in the Finder, do the originals have the same size?

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.
