I have a few photos open in Preview, and they have a slight blur to them. Then I open the same files in photoshop, and they are crisp.

Anyone else notice this?

And I am a professional photographer, so no, the images are not out of focus

Quad 8-Core 3.0, Mac OS X (10.5), MacBook pro, iMac

    Yes. If you view a picture scaled in Preview, it is blurry on my system as well.

    Same for me here. The image is fine at full size but when i scale it down the image gets very blurry.
    Thought it was supposed to get sharper the smaller images get.
    Hope they fix this fast.

    It was the first thing I noticed. I went back to Tiger, took a screen shot of my jpg, looked at it in Leopard and the Tiger screen shot (tiff) looks much sharper than the Leopard view at the same size.

    Yuck -- I use Preview extensively to view scanned documents and faxes (usually both in TIF format) and this new version makes them almost too blurry to read!

    How can we fix this? Please tell me there's some magic "defaults write ... " that will get the old scaling algorithm back!

    I copied over an older version of Preview from my 10.4 machine, and when I use it to open files, they open as before and are not blurry. So I suppose I can just use it for now, until this gets fixed. I renamed it to "Preview_Old" to avoid confusion.

    No only is scanned in text almost entirely unreadable in preview, but the "copy and paste" ability has seemingly gone away.

    I used to scan in Latin text for the class that I teach, and often copy and paste selections in Pages documents as I needed them. Now the only way to do this is to do a screen grab, then copy and paste that screen grab in.... and the result is a blurry mess.

    Does anyone know if it is possible to download the old version of preview from somewhere? This has really become a huge problem for me.

    I saw the same blurriness too. I thought I was imagining it, because the difference is subtle, but I knew it was there. I did as one of the above posts suggest -- I went to my macbook pro and copied the older version of preview onto my mac pro, and it's back to being sharp again.

    Hopefully Apple will address this in a future update.

    Oops -- bad news.

    The 10.5.1 update to MacOSX no longer allows the old version of Preview to run.

    Thanks, Apple! Now we're stuck with blurry images until .. ?

    I am experiencing the same problems with Preview. Not only do the pdfs appear blurry, but the redraw is maddeningly slow during scroll or page jumping.

    Agreed, Preview from 10.4 was much smoother. Trying to run it after the 10.5.1 update results in the "cannot use the application..." error message. As per other threads, I've tried moving the old app around and repairing permissions. No change.

    I know this isn't a top priority, but it would be nice to have Preview on the working side.

    Please Apple? We'd like to be able to read documents without resorting to another pdf viewer.

    I too have this blurriness. Sadly, this problem is still present in the new update (10.5.1). The difference is very clear if you compare some (same) picture between Preview and QuickLook - at the same size. Preview is very important for me too and hope it will be repaired soon.

    Yep, I noticed this straight away too. Strange considering Preview is the primary way of viewing images on a computer system designed for creative/arty people.

    I've downloaded the press release screenshot for the new Final Cut Express 4, which is a 2400 x 1621 image. If I open it in Preview and Zoom To Fit, all the text looks as if it has a slight vertical motion blur on it. However, as I zoom into the image, I can see that there is a tremendous amount of detail and clarity in the image. It's clearly Previews fault as Photoshop would have no problem at all resampling this image but maintaining the clarity.

    Also, I don't know if anyone else noticed this, but if you click the + or - buttons in Preview 4.0 to zoom in or out of the image, it zooms and then JUMPS up as the scroll bars appear! This is rubbish. I want to zoom IN, not zoom in THEN shift up.

    Apple really needs this feedback. Since they don't monitor these discussions for technical issues I hope someone (or everyone) has sent feedback to Apple.

    Here's an example showing what Preview 4.0 does to scaled images:

    Here's a trick to keep the version of Preview from 10.4 running after the 10.5.1 update. Works for me, but you're on your own with it:

    use the 'show package contents' command to open the old version of preview and the new version of preview. Copy the 'info.plist' file from the new version of preview to the old version of preview.

    Then 'compress' the new version of preview and delete the app to avoid confusion.

    If none of this makes sense to you, you probably shouldn't do it. I'd suggest replacing the modified Preview with the 10.5.1 version prior to any system updates, in case Apple fixes this someday.
