File size changes after color adjustments

Anytime I adjust/edit a photo in iPhoto it results in a saved image that's half the size of my original. I wanted to bump the contrast and print a photo, but the image goes from 4MB to 2MB after a simple color adjustment. Does anyone know how to stop this?

Is there anyway to save the copy without a loss in file size
No. Like I said, it's in the nature of jpegs. Jpeg is a lossy format.
It seems to be an iphoto issue rather then a jpeg issue.
Don't think so.
When I make adjustments to a jpeg in photoshop and save it, the file size is not effected.
Where are you seeing that reported? I just auto-coloured a jpeg with CS4 and saved it at 9 on Photoshops scale of 12 and the file size reported in the FInder went from 4.5MB to 1.1.

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.

XML File size changed

Hi, All:
I wondering why the XML file size changed after go through DB using CLOB. The original size is 1KB, but after I use the PUT and GET method, the size changed to 8KB. There is a lot of space appened to the content.
Thanks a lot!

Can you provide an example of the code you are using for the put / get method. In SQL*PLUS I do not see what you are talking about

After copying a file from NTFS to HFS volume, file size changed when viewing in Windows

Hi guys,
I have a Mac Air running Mavericks on a HFS partition and Windows 7 on a BOOTCAMP NTFS partition. I have some files that I want to read/write from/to both systems. Since OS X can't write NTFS and Windows can't write HFS either, and I don't want to use any 3rd-party tools/drivers, I have to adopt a "stupid" way: in OS X, I copy those files from NTFS to its HFS partition, make changes, then switch to Windows and sync them back to NTFS.
The problem is, after I copied a file from NTFS to HFS in OS X, it seemed ok. But when I switched to Windows, the very copied file in HFS partition had its size changed (bigger) although I didn't make any changes to it in OS X yet. This happens to almost every file I copied, text and binary. For those text files, I tried to open it with EditPlus in Windows and EditPlus reports the correct size on the status bar.
How could this happen?

I am not sure if this is what your seeing but...
The same unaltered file on two different volumes might use different amounts of disk space. This is because a 'disk' is divided in to 'blocks' and a block (also historically known as a 'sector') is a certain minimum size. So if disk-1 has a block size of 512 bytes and disk-2 has a block size of 1024 bytes then a file containing just 10 bytes will use up twice as much space on disk-2 as disk-1 even though it is the exact same file.
Beyond that, Macs can add additional information like Spotlight tags, labels, icons, etc. which make a file bigger. If you are modifying a file then presumably that also implies adding additional content e.g. for a Word document more text and this will make it bigger. Also depending on some programs are configured or designed 'deleting' text may only mark it as deleted and not really delete. This can apply to older versions of Word which has a 'Fast Save' feature, new versions have removed this and do a proper delete.
You would have to give more details like what you are doing to the document, what kind of document, and what the two sizes are.
Finally, there is one other potential difference, some systems and manufacturers use 1024 as a unit for measuring file and disk sizes, some use 1000. It will be the same number of bytes in each case but 1000 bytes in one case would exactly equal 1MB, and in the other it would be 0.9765MB.

File size changing when pass through after effects (180Mb file goes in and comes out 33GB on export)

im processing a video recorded of an interview where the lighting was not very good on the interviewee
im brightening up the light on the interviewees face
the file was a 180Mb H.264 file on import
when i export the file its coming out at 33GB in size.... im not sure why this is
i have chosen the default setting "lossless" as the format for export
i just want the file to export the same size and quality as it was when i imported it
what options should i choose for this? AE does not seem to tell me how big the end file will be and it takes 1 hour and half to process this 2 minute interview so it will take me an awfull long time to get to the bottom of this if i try by myself
thanks

It doesn't "increase" the file size. You're making a brand new file.
What you put into After Effects has nothing to do with the resulting file. You can have an AE composition with no footage whatsoever and the resulting file will be much larger than 0!
After Effects works internally with completely uncompressed pixel data, so no matter what you toss into it, it produces whatever you tell it to produce. As Mylenium points out, you made an uncompressed final file.
Your original video file is VERY compressed. So, of COURSE uncompressed video is going to look massive by comparison.
Read Mylenium's link to understand a bit more and go here to learn AE: Getting started with After Effects There are lots of "gotchas" like this that'll bit your butt if you skip this basic training stuff.

Why do file sizes change when I use "Process Multiple Images" to add watermarks?

Hi,
I'm using Elements 11. In order to add watermarks to many JPG pics at once, I use the function "Process Multiple Files".
I select a source folder and a destination folder, and adds a three digit serial number to each file. I do NOT tick the checkbox marked "Change picture size". After that I define the watermark I want printed on my pics and hits OK. All the files in the source folder are processed and saved, with a new name in the destination folder. Fair and square.
But. The file size of the new file is heavily reduced, compared to the original. It goes from 10 MB down to 500 KB (in general). Why is that? Is there any way I can prevent it?
Regards,
/Mikael Lindgren

Or you can uncheck the convert files box to save them in their original format, or select one of the lossless formats PSD, BMP, TIF. What is most appropriate depends on what you intend to do with the watermarked versions.
Cheers,
Neale

Render file size bigger After Effects CC 2014

Hello, this seems like a silly question, but ever since the 'After Effects CC 2014' update my rendered files seem to be enormous in comparison to the files I rendered before the update!
I don't see why the update would have adjusted my render preferences, but it must have done as a 2min clip that rendered at 140mb before is now 10GB!!!
My knowledge of codecs and compression is limited but I had a good preset before the update which now seems to have changed (although I have always been rendering h.264/full quality/no audio so I don't understand how the file size can change so drastically).
Has anyone else experienced anything similar?
If not could you please advise me on how to render these files to a suitable size. Like I said they need to be h.264, 1920 x 1080 with no audio.
Thanks.

After Effects CC 2014 no longer supports the output of many delivery codecs, such as Mpeg4 and H264, through the Render Queue.
You can output far more formats, and in greater quality, using Adobe Media Encoder. You can send AE renders directly to AME from After Effects. You can import AE projects directly into AME. And you can also render high quality and/or lossless formats from the AE Render Queue and then re-encode them from AME.

CS5 indd files occasionally change after saving and reopening

Occasionally the contents of my InDesign document will change after saving and re-opening. No errors reported during the save however when the file is opened a text box may be out of place or leading may be messed-up on a few random pages or some of the recent changes may not have been saved. Any ideas?

There was no direct indication that you created the code in a standard module. I asked because you reported that the code works in the sample workbook that you downloaded but not in your own workbook.
I don't know what else to suggest at the moment.
Could you create a stripped-down copy of the workbook (without sensitive information) and make it available through one of the websites that let you upload and share a file, such as Windows Live SkyDrive (https://skydrive.live.com),
FileDropper (http://filedropper.com) or DropBox (http://www.dropbox.com). Then post a link to the uploaded and shared file here.
Or register at www.eileenslounge.com (it's free) and post a message in the Excel forum. You can attach files up to 250 KB to a post there (zipped if necessary).

Alac file size changes when added to iTunes

Hello,
I've converted some FLAC files to ALAC using dbPowerAmp. The file bit rate remains unchanged. However, when I add the ALAC files to iTunes, the bit rate shown in iTunes is reduced.
Example - Alice Cooper, Hello Hurray
FLAC Bit Rate - 4608 kbs
Converted ALAC Bit Rate - 4608 kbs
iTunes ALAC Bit Rate - 3012 kbs
Any ideas what's going on?
I'm using iTunes 10.7.0.21
Thanks.

Nothing has been changed.
Sounds like iTunes & dbPowerAmp figure the bit rate differently.
dbPowerAmp uses the uncompressed file sizeand iTunes figures the compressed file size.
Since the file is smaller, the bit rate will have to be lower.

PDF File Size changes

I have just upgraded from CS3 to CS5. I set my documents up for print and when saving to pdf small file size the file size have increased dramatically. A typical previous size would have been about 600 to 700k now the files are comming out at about 1.7 mb. I am getting complaints about this from clients. I have tried the save as reduced file size pdf, but it really doesn't make that much difference. Can anyone help?

Try creating your own job options file in Distiller. You can change the job options setting to reduce the file size as you see fit. You may want to make sure you font subset or you can turn off font embedding entirely. You can make sure your graphics are as small as you feel appropriate.

File sizes explodes after removing hidden information

After removing hidden content in Acrobat Pro X (Tools/remove hidden content or Tools/sanitize) the file size increases, up to 10x (2 MB -> 20 MB). Save as optimized PDF only partly reduces the problem, file is still 3-4x the initial size. Document was created with Adobe PDF writer, but this problem occurs in principle also with other PDFs. Bug? Necessary? Workaround? Any help is appreciated. Thanks in advance!

Any one found a solution to this problem?
I'm having it too, acrobat xi pro 11.0.10...
Original file size before cropping ~27MB
Same file saved as optimized PDF before cropping ~12MB
Original file size after cropping ~27MB
Same file saved as optimized PDF after cropping ~12MB
Original file saved as some other file name after removing hidden information ~60MB
Same file saved as optimized PDF after cropping AND after removing hidden information ~60MB
What on earth is going on?

Why do file sizes change between Windows to Mac drive?

I'm moving a large number of files from a 3TB Windows NTFS external drive to a 3TB Mac OS Extended Journaled external drive.
Now, comparing the original file to the copy, I'm finding that the file sizes in the Get-Info window are different on many of the files. (I would say the majority of them.)
Did something go wrong and do I now have corrupted data across thousands of files? Or does a NTFS drive calculate size differently as a Mac-formatted drive, even though the files are identical?

Does it happen on all kind of files, or just txt files?
Usually, it comes from the fact that Unix (from which OS X closely derives) and Windows don't have the same way of "recording" changing lines in txt files: in DOS and Windows, going to the next line, whether manually when typing or because you imported a txt file made by someone else (or another machine) means using a "carriage return" (yeah, I know, sounds old), where Unix uses a "line feed".
A carriage return will first send the carret back to the beginning of the last line you typed in, before switching to the next line so you can resume typing, whereas a line feed will jump to the next line directly. This leads to some invisible extra characters being typed, and since each digit or key press brings its own byte or octet in the balance, your files might end up being heavier under one platform than they were in another.
The Notepad application in Windows is known for its poor text wrapping (which it makes up for by being a good tool for coding, for the same reason), with the user/writer needing to feed its own carriage returns in the text, when Wordpad is more user-friendly, with better text wrapping, but doesn't show the same flexibility that Notepad has.
The same principle applies to all txt-based files, hence to .log files too. And log files tend to be created by applications for this purpose or that, without you knowing it.

Why does the file size change when put into an iDVD project? And problems with dual layer discs...

I exported a short video of mine from Final Cut Express and the size of the file came out to 7.3 GB. When I put it into an iDVD project, it says that the file is only 800 MB. I tried just burning it onto a dual layer disc anyway to see if it might still burn at the original file size, but the disc came out unusable for some reason, and obviously hadn't been burned anywhere near full-capacity. So, I tried it again, and the exact same thing happened.
I guess my first question is: why is iDVD changing the size of the file? I want the quality to be the best it can be, so keeping it at 7.3 GB as opposed to 800 MB is rather important.
Secondly, why did the dual layer discs come out unusable? I've burned single layer discs before and they haven't been an issue. Also, I know for a fact that the drive can burn dual layer discs, so that isn't the issue.
Thanks in advance to anyone who can provide me with help on this issue.

Guessing here but it looks like you edited/exported an SD/DV sequence of about 30 min in FCE. DVD needs to be MPEG-2 so iDVD compresses the original file down to the size that you report.

The quality will be what the MPEG-2 compression and the software allow for. MPEG-2 is DVD standard .... there's no way around that.

Guessing again but it would seem that you burned a Data DVD instead of a Video DVD which would be unusable by a set-top player. As I said above you can't get around DVD standards.
If by any chance your video was HD originally you can try to go the Blu-Ray route using Roxio Toast or FCS 3 (discontinued) or FCP X. You will also need a Blu-Ray burner.

Word file ownership changes after edit/save.

This may be a server issue more than Office, but I've come across some articles relating to this problem in Samba, and thought it might be similar.
I'm the Network Admin for a school district. We have a file server that is setup with a file and folder structure that allows students and teachers to access and share documents. One teacher came to me with a problem. Students are able
to create and save Word documents to an assignment folder. The teacher then goes into the document, makes changes and enters notes, then saves the document back to the folder, overwriting the original. The problem is that once she has done so,
the student can no longer access the document.
After investigation and testing, I've found that ownership of the file is changing from the student to the teacher. This is a problem based on the way that the ACL is set on the folder. The students' access is based in the creator/owner attribute.
The fact that the ownership is changing once the teacher opens and edits the document is causing the student to no longer have access to the file.
My question is, is there a setting or other change that can be made to Office so that ownership is not transferred to the teacher? Giving each user explicit rights to each file and/or folder isn't really an option when I have 3000 students to
deal with. Again, this may be a server side issue, but I've not seen this problem with other programs.

I'm picking this up because I have the exact same problem.
Students are given Write access to a folder (So they can save their work)
Teachers are given Modify acccess to a folder (so they can add comments, etc)
CREATOR/OWNER is given Read/Execute so students could read teacher comments, but not make changes to the document once it has been saved.
When I test it with my admin account, it works great. I can update the document and the student can open it to see my comments, but not change the document anymore without saving to a different location.
When I test it with a teacher account, the document changes ownership as soon as the teacher saves. Once the ownership changes, the student no longer has permissions through CREATOR/OWNER and they can't open the document to see the comments anymore.
I can't see why this works when my account makes the changes, but not when a teacher account does. We are doing the exact same things in Word.
Here is an example of the permsions as they exist on a sample document. In the example, my admin account (which works fine) gets it's permissions through BUILTIN\Administrators:
PS H:\> $acl = get-acl "L:\TeacherShare\S2 3(A) Study Hall - Half Year\Submissions\StudentWork.docx
PS H:\> $acl.access
