Why the size of the tif file is different in photoshop workspace compare to the Preview in Finder?

1. Why the size of the tif file is different in photoshop's workspace compare to the Preview in Finder?
Please look at the screen captures.
Bottom left panel of Photoshop's workspace.
Finder's Preview.
2. I have an imac with 8gb ram, and assigned 6gb ram to photoshop use. But when I worked on a 24mb tif file, photoshop was lagging. And at the bottom left panel of Photoshop's workspace, the doc size is something/1gb. The tif file is only 24mb, why is it slow in photoshop? I have a lot of ram.
Let me know, please.

Thank you MIchelPM for giving me a very detailed explanation.
So I understood why the photoshop doc size is bigger when working in photoshop.
Regarding to your questions:
1. How full is your Mac's hard drive?
    Not even 30% full, I even have a 1TB backup hard drive connected.
2. How many applications do you run simultaneously in the background while working in another application?
    I usually only have photoshop or illustrator opened. Sometimes I ran 3-4 tif files at the same time, but when a big file (ex. 24mb tif) gets very slow, I closed all other files and programs, and "purged all" in photoshop, yet that 24mb tif file was still slow.
   I checked photoshop's ram and cpu usage in the activity monitor. Rarely photoshop's cpu usage would hit 100. But when I worked with the 24mb tif file, it would used all the ram that I've allocated to photoshop.
But the myth is, my coworker who worked with the same file in CS4 with only 4gb ram in their imac don't have photoshop slowed down, when I have double the ram and CS6.
3. What year, screen size, CPU speed of your Mac?
   I have 27" imac,
   • 2.9GHz  2.9GHz quad-core Intel Core i5 processor (Turbo Boost up to 3.6GHz) with 6MB L3 cache,
   • 1TB (7200-rpm) hard drive
   • NVIDIA GeForce GTX 660M graphics processor with 512MB of GDDR5 memory
4. What version of OS X is your Mac using?
    Mountain Lion with the latest updates.
5. What version of Photoshop are you using?
   • Photoshop CS6

  • Why is my word and pdf files so large? How can I reduce the size?

    My document contains mostly photos from a database via a path to the actual jpeg photos on disk.
    There are 39 jpeg photos + a small amount of text with each photo.
    The 39 jpeg photos on the disk add up to be 5.79 mb.
    If I export the crystal reports document as [Microsoft Word (97-2003) Non Editable] the, the file size is 36.8 mb.
    If I export the same data as a [Microsoft Word (97-2003) Editable] the file size is only 3.1 mb.
    That is a difference of 33.7 mb! Why?
    Also, when I export the same data to a PDF file it is much larger than I think it should be; 12.7 mb.
    Why is my word and PDF files so large?
    How can I reduce the size of the word and PDF files? (without reducing the photo quality).
    Are there any tools to post process the Word or PDF files to reduce the file size?

    You can't, extra size is to hold the details

  • How do I reduce the size of a Keynote file beyond the reduction of zip?

    Kindly advise.

    How do I reduce the size of a Keynote file beyond the reduction of zip?
    Why do you need it smaller, what size is the file, what's in the file that you think is making it large.
    If your trying to reduce file size to send by e-mail, use a file transfer service instead:  Dropbox.

  • I need to reduce the size of several pdf files before transferring them onto a research database. Each file is made up of 100 images (pages of diaries)

    I need to reduce the size of several pdf files before transferring them onto a research database. Each file is made up of 100 images (pages of diaries) & is up to 1.36 GB in size. I have tried reducing file size in preview but the images are unreadable. Any ideas? 

    WHen I want to reduce the file size, I either use "Optimize Scanned PDF", or more often use "Reduce File Size". Both are on the Document menu. The Reduce File Size selection has some limited customization that is used, when selected.

  • How to increase the size of Redo log files?

    Hi All,
    I have 10g R2 RAC on RHEL. As of now, i have 3 redo log files of 50MB size. i have used redo log size advisor by setting fast_start_mttr_target=1800 to check the optimal size of the redologs, it is showing 400MB. Now, i want to increase the size of redo log files. how to increase it?
    If we are supposed to do it on production, how to do?
    I found the following in one of the article....
    "The size of the redo log files can influence performance, because the behavior of the database writer and archiver processes depend on the redo log sizes. Generally, larger redo log files provide better performance, however it must balanced out with the expected recovery time.Undersized log files increase checkpoint activity and increase CPU usage."
    I did not understand the the point however it must balanced out with the expected recovery time in the above given paragraph.
    Can anybody help me?
    Thanks,
    Praveen.

    You dont have to shutdown the database before dropping redo log group but make sure you have atleast two other redo log groups. Also note that you cannot drop active redo log group.
    Here is nice link,
    http://www.idevelopment.info/data/Oracle/DBA_tips/Database_Administration/DBA_34.shtml
    And make sure you test this in test database first. Production should be touched only after you are really comfortable with this procedure.

    pdf file is too big (7MB). Need a pdf file with max size 4MB. How to minimize the size of a pdf file?

    The other alternative is the Save As Other>Reduce File Size. The PDF Optimizer gives you more control. You might also use the audit feature in the PDF Optimizer to see where the size problem is coming from. You might find that in the WORD file you can select and image and then go to the FORMAT (pictures) menu and select compress for all of the bitmaps in the file. That will typically use 150 dpi by default that is adequate for most needs.

    No one here can help you with this, nor can/will Apple. You need to take this up with whoever you purchased this phone from.

  • TS3510 I have 3 different apple devices using the same Apple ID and would like to use FaceTime to call from one device to the other.  Do I need a different Apple ID for one of the devices in order to do that?

    I have 3 different apple devices (iPod Touch, iPad and MacBook Pro) using the same Apple ID and would like to use FaceTime to call from one device to the other.  Do I need a different Apple ID for one of the devices in order to do that?

    I found this on a related question in the Community:
    Yes you can do it. I do it with 4 different devices all using the same Apple ID.
    You need to associate different email addresses for each device in order to use those email addresses as the "contact at" email address. The reason the calls are dropping on you now is that what you are trying to do is like calling yourself on your own phone.
    You can also create new iCloud accounts on each device simply to use for FaceTime, but I'm guessing that the users of the other two devices have their own email addresses which will make this work for you quite easily.
    Take a look at this for more information.
    The seems to go against what Gail said and the issue you raised about buying dup apps was my first concern.  If this other post is correct, how to I set a different "contact at" in the iPod Touch?

  • Why is the size of my pdf file so large

    In the templet,I use a font type "Simsun" for Chinese in the subform.
    This font type is added in the output desginer by "font setup" .
    And this font has been existing in my os.
    When I generate a pdf file, the size reaches >6M.

    Even if you specify Helvetica, Acrobat and Reader substitute a private version of Arial anyway, so all you're doing by specifying Arial is needlessly adding space. The problem is you can't go back and the fields to use Helvetica and see the file size reduction you might expect. This is due to what I consider to be a bug that I'm hoping will get fixed. So you have to start with a fresh PDF, but you can copy the old fields to the new if you first change them to Helvetica. Or if you know how to hack the PDF you can salvage it after changing the fields to Helvetica.
    I was JUST about to type this. I went into my revised pdf and changed the form text boxes to Helvetica and it didnt change the file size. However  I re-created the file from scratch and it is now keeping the file size at the original size. Thanks to both of you for the help!

  • How do I find the size of a video file in iTunes store?

    Is there any way to find out how big a video file is before I download it to my computer? I see that movies show the file size in the product description, but what about episodes of a TV show? Or a complete season? Or a video in iTunes U?
    I tried "right clicking" (or whatever that's referred to on a Mac, sorry, I just recently got my Mac) to get info on a few files, but it says the size is unavailable. I have an iPod Touch I'd like to get videos for, but I don't have a ton of space after putting all my music on it, so that's why I'd like to know the file sizes in advance.

    You can figure for a 1 hour TV show - about 40-45 minutes of video - you will have a file size of about 450-550 meg.
    A movie such as Pirates of the Carri..... will weigh in around 1.6-1.8 gig.

  • How to determine the size of a flat file attachment in a mail sender cc?

    Hi
    I use PI 7.11
    I have a scenario where a flat file attachment is being picked up by a MailSender adapter and if the size of the attached flat file is larger that 500 bytes the receiver is A and if the attachment is less that 500 bytes the receiver is B.
    I have checked the Context Object list in the Conditions section of Receiver Determination, and it seems, that only the file adapter allows for validation on the file size.
    I contemplated an extended receiver determination but the attachment is a flat file which just needs to be passed thru without being converted to an XML document, so my source document is not of XML format.
    An other but not very nice way would be to use an intermediate folder to drop the attachment in and from there use a file sender adapter and thus get access to the filesize attribute in my receiver determination, but I would like to avoid this.
    Any suggestions?
    BR MIkael

    Hi
    I have decided to make a module, where I plan to place the size of the attachment in the Dynamic Configuration variable "ProcessStep", but to my surprise, it seems that all the context objects in the receiver determination condition section are of type String and hence it is not possible to make a condition where I test for whether the value is smaller than say 500!? Only equal, NOT equal and LIKE are available (EX seems to be disabled as this probably only works in an xpath.
    Would one way be to use the xpath expression like this ns1:Main\ProcessStep < 500 where ns1: http://sap.com/xi/XI/System?
