Preview Blurry

Hi
I've noticed that this has been discussed almost 2 years ago - has anything been done about it?
http://discussions.apple.com/thread.jspa?messageID=5889735
I'm finding the reading of scanned images a real pain on preview because the images become so blurry when they are resized - this was never a problem on older versions of preview.
Anyone know what i can do?

I know exactly what you mean. The difference is subtle, but it is there, and for things that have text, it can be just enough to make the text too difficult to read. Not sure if everyone will be able to tell the difference with this example or not (it may depend on how well your eyes or glasses work):
Actually, PSElements doesn't do a very good job at the 33% size either.
As discussed in the previous thread you cited, I did the hack to be able to run the Tiger version of Preview in Leopard. Most of the time I don't bother because the issue isn't critical for the sorts of things I use Preview for. But it is definitely still there and still noticeable under certain circumstances. There is no solution, except to up the size or use a different program, including the Tiger version of Preview, if you still have it somewhere and want to do the hack to get it to work.

Font in Preview blurry

In Yosemite, when I look at a pdf file in Preview the fonts are blurry compared to Mavericks. The upper image below is a screenshot using Mavericks, and the lower one is from Yosemite.
I tried fiddling with LCD font smoothing in preferences, and restarting, but nothing changed. Anyone else having this issue, and maybe found a solutions?

Dear Stuart Field and concerned Apple staff,
Apparently it is because the anti-aliasing algorithm used by Preview.app in Yosemite is incorrect.
The same problem has been raised and discussed recently on other sites including Reddit and StackExchange.
A comparison of the same PDF viewed in 10.9 and 10.10 can be seen below (images taken from this post).
10.9 (correct and beautiful with colorful shadow):
and on 10.10 (weird, grey shadow):
Presumably this bug is coming from the incorrect adjustment for Mac family with retina display.
Note that this bug does NOT happen in Safari, which is quite amusing.
Sincerely,
Leo

Full screen preview - blurry?

Can anyone tell me why my full screen previews are slightly blurry? They are nice a crisp when I view at 100%, but a bit blurry full screen.
Updated CS5
Thanks.

Have you selected "Generate Monitor-Size Previews" in Preferences>Advanced?

Preview blurry images?

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

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.

Camera App Photo Preview Blurry

Heres an interesting issue i found on my iPhone 5. If i use the camera app to take a photo, then swipe left to view the photo. The last taken photo is extemely blurry. Most camera preiews do this then load the clear photo, but thisone stays blurry. Ifi go into the photos app and view the photo its ok, also if i rotate the screen on the blurry photo it will be clear again. Anyone else having this issue? It is bothersome asi always swipe left to check the photo i just took. Have tried restarting camera app and hard reset. I imagine Apple could release a software fix for this?

Wow I'm surprised no one is talking about this yet. My brother found this happening in his iphone 5 within a matter days of use. He told me about it and now that i just got my iphone 5, i discovered it to be true myself.
This occurs regardless whether the camera app is launched from the lock screen or home screen. It seems to happen only when you swipe right from the camera view to get a quick glance at your photos. The last photo will appear blurry when viewed through the swipe method rather than the traditional method of doing so through tapping the box on the lower left . Like Egibbys21 described, rotating the photo will clear it up. However I found that this problem repeatedly happens when a newer photo is taken in the opposite orientation of the last. Also, so long as the blurry view isn't cleared up through rotating the photo like how Egibbys21 described, all last taken photos, regardless of orientation, will appear blurry when viewed through swipe method.
It is somewhat unfortunate and seems either users don't use the swipe function like they do in windows phone, or those photos have been largely mistaken as truly blurry. I hope others will be able to duplicate this issue and bring this up.

Previews are Blurry in Bridge CS6

On several occasions I have seen that some images are previewed blurry in Bridge CS6.
I have set the preview to full resolution/quality, so this is not the issue.
When it happens, it happens like this:
1. I have a layered file, and the preview is good and sharp.
2. Then I sharpen, and the preview is blurry.
This has occurred numerous times. I thought the preview was corrupted, so I deleted the file, and hauled it back from the trash, so a new preview would be built.
Again, this new preview would again be blurry. (Out of 20 files, two had a blurry preview - and the files themselves were NOT blurry).
Flattening such a file does not help. While the flattened file is also sharp in Photoshop, its preview remains blurry. A copied file also has the blurry preview.
I don't see any correlation with image dimensions, file sizes. Some images just randomely are previewed blurry in Bridge CS6.
The only correlation I see is that it is ALWAYS SHARPENED IMAGES that are previewed blurry (the unsharpened versions always look much sharper in Bridge CS6)
What can I do to have Bridge CS6 preview ALL images correctly?
edit: I purged the cache for this folder, and the rebuilt preview is again blurry.
Even worse, now 50 out of 100 images have blurry previews.
How can I get previews that I can work with?

I have a latest generation MacBook Pro retina, so that should be fine.
It actually worked when I purged the cache for this folder a second time. The blur went away.
The first time I had done a "select all" images to show Bridge which previews I needed rebuilt - not necessary, maybe that was an overload for Bridge.

Landscape after portrait: preview is blurry

I noticed a weird preview bug in Lightroom 4.3 under Windows 7.
In Library mode, preview window set for single large preview:
1. Hit a portrait-oriented photo in the filmstrip below. The photo is previewed properly (sharply)
2. Hit a landscape-oriented photo in the filmstrip below. The photo preview is blurry
3. Hit another landscape-oriented photo in the filmstrip below. The photo is previewed sharply
4. Hit the landscape-oriented photo from step 2 again. The photo is previewed sharply
Every time I hit a landscape-oriented photo immediately after a portrait-oriented photo, the photo is previewed blurry. But if the same landscape-oriented photo is previewed immediately after another landscape-oriented photo, then everything is fine.
In other words, previewing a portrait-oriented photo screws up the preview for the next landscape-oriented photo. It looks like not every portrait-oriented photo has this effect. But the ones that do have this effect consistently in 100% cases.
I read the list of fixes in the upcoming 4.4 version and they mention the fix for blurry previews on Mac only. I wonder if this is somehow related. Hopefully they'll fix this one as well.

Here's a sequence of screenshots that demonstrate the problem. (I hope they will come throigh well enough to demonstrate the effect)
1. This is the first preview of a portrait-oriented image. Preview mode is set to FIT. The preview is sharp. (In all screenshots I will use three images which can be seen here selected in the filmstrip.)
2. Now I switch to a landscape-oriented image. The preview is blurry. This is the problem in question.
3. Now I switch to another landscape-oriented image. The preview is sharp
4. And now I shitch back to the image from step 2. The preview is now sharp
So, the issue here is demonstrated by the difference between previews in steps 2 and 4, even though the same image is being previewed in both cases. In order to see the difference one needs to open full-resolution screenshots.
P.S. I see that the forum engine resized my images (originally 1920 x 1200), but the difference in the detail in the piece of wood is still noticeable. Here's 100% crops from 2nd and 4th screenshots

Full screen preview and slideshow are blurry / fuzzy

Hi folks-
I just upgraded from CS2 to CS4, in part to improve efficiency of selecting photos - I wanted the zoom and loupe features. Unfortunately a very basic function has been compromised and I'm hoping there's a solution: In both full-screen preview and slideshow the full-screen image is notably blurry. This is a problem for two reasons: 1. I can't judge pictures accurately by just flipping through them in full-screen mode (without zooming to 100% to see if they are well-focused). 2. I can't use Slideshow for, well, slideshows. I've had to resort to keeping another app (like Windows Picture Viewer) open just to be able to quickly flip through and evaluate images full-screen or to show slideshows.
I've tried setting all the options related to image quality (they mostly have to do with caching thumbnails and speeding 100% viewing); I've tried purging the cache files. Nothing helps.
Any ideas? Thanks!

It seems to me that there is something wrong with it.
I am trying Bridge CS4 as a viewer for my JPEG files.
I also noticed that the previews were fuzzy. I activated the high-quality previews as well as the option to generate the previews at screen size.
Here's what I noticed. I went to check out a specific photo that is quite sharp with a number of straight lines, angles, details, where it's very easy to detect a lack of sharpness. That photo immediately looked fuzzy to me, which didn't jive with my memory of it. I quickly opened it in other viewers, which displayed it as intended with all the expected sharpness.
So, I went through the settings to see where the problem could be and I immediately thought of checking the box to get software previews instead of hardware, restarted the app, purged the cache, tried again. There my photo had recovered its sharpness, or at least most of it. I thought I found the culprit, but not quite.
I went to browse other photos and found one in particular with a lot of fine detail (hair) and that photo also didn't display all the sharpness that it should have (I was still using software mode). The difference was very slight and to make sure of it it required A/B comparison between Bridge and PS, but there was a difference.
Now I tried the opposite. I went back to hardware rendering mode, restarted, purged the cache, tried again. That second photo looked alright in preview, but the previous photo looked fuzzy again.
So, it doesn't work the same way for each photo...
What's the main difference between the first photo, obviously fuzzy in hardware mode, and the second one, alright in hardware mode but slightly fuzzier in software? The ratio. The first one is a vertical photo, the second one is horizontal (close to square).
I quickly checked other vertical photos and they showed the same behavior...
Now staying in hardware mode, I noticed something else. When I preview the vertical photo and click on it, or double click, it quickly jumps, switching between 2 versions of the photo: the one displayed originally (fuzzy) and another one, with a very slightly different size, which is sharp. During that manipulation it also briefly displays "100%" at the top of the screen. It doesn't stick when you click and immediately switches back, so it looks like a glitch.
Now in software mode, I tried the same, this time you can click once on the photo (which is originally displayed *almost* sharp). When you click once, it displays "100%" but also displays a very slightly smaller version that is clearly fuzzy. Clicking again goes back to the other, less fuzzy one, but doesn't display "100%" this time.
Doing the same test on horizontal photos shows no change that I can see.
So, it seems to me that in the preview mode, Bridge has trouble displaying some photos (vertical ones?) in their actual resolution (100%)
and since there is a slight resizing going on, it brings fuzziness. This doesn't explain the very slight fuzziness seen on horizontal photos in software mode.
Now I'll mention, for those still awake, that I saw no fuzziness on the same vertical photos when I go to Review Mode with *hardware* rendering. Photos there are sharp. Now if I go to the review mode with software rendering enabled, vertical photos are not 100% sharp (akin to the small difference I mentioned earlier while in software mode), while they are sharper in preview.
To sum up, it seems that the only configuration that gives me consistently 100% sharp (=as they were meant to be after post-processing) photos no matter what their orientation, is when I stay in hardware rendering mode and use the Review Mode, instead of preview.
This all really smells like a bug.
For info, I am using Windows 7 and an ATI HD4850 card, and this only about processed JPEG files, not RAW files.
Perhaps the preview is really meant as a quick preview and not a tool to view final photos at 100% accuracy...

Photos Blurry in iPhoto vs Photoshop Elements or Preview

I've noticed in iPhoto 5.0.4 my photos don't appear to be presented as sharp as they do when I open the same photo in Photoshop Elments 2 or in Preview. I double click the photo to go to edit mode. I have the same photo open in the other applications. iPhoto is a tad blurry.
Has then been fixed in iPhoto 6?
Thanks for any advice
Kelvin

Also take a look at PhotoPresenter. It has some terrific animated themes and allows putting both slides and video files in the same slideshow. It will integrate with iPhoto also.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto 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 written an Automator workflow application, 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. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

When I preview a song in iTunes, the album art preview shows up blurry

So anytime I preview a song in iTunes store, whenever I click on the small album art icon (at the top) to bring up the smaller player, the album art shows up blurry.
Has been happening for the past three or four iTunes releases. How can I fix it?
When I purchase the song, the album art downloads just fine though. Funny thing is, if I preview a different song from the same album, the album art loads fine. Not sure whats going on.

Make sure that these two options in Edit > Preferences > Store are turned off:
Then exit iTunes and open it up again. Your metadata entries should then be persistent - with these options checked iTunes will be comparing what you have with the information held in the iTunes Store, and will overwrite with the latter for Store purchases (and if you have iTunes Match). If you have any iOS devices you should also turn off Show All Music under Settings > Music.

Poor quality in preview - image is blurry

To date, I have not had any issues with the preview quality matching the actual image quality.
I have not made any hardware por software changes. Image files are in raw, jpg and tiff formats.
This issue appears to be only with raw files. The image in preview is extremely blurry, yet when the
file is opened it is tack sharp. I have checked all my preference settings and cannot figure out what is goin on.
I have tried purging and refreshing the cache and nothing seems to work.
I am running PS CS4
Windows Vist 64 Ultimate
Please help!
Update: I have changed raw preferences to apply to preview images only. The image qulaity only seems to improve when I
purge the cache for the slected images. I have the cache option for export to folder when possible checked. I have tried to purge the cache for
all images but the preview does not imprevoce unless I purge selected only.

This may be dumb but when it recently happened to me, I opened one image in adobe camera raw and increased the clarity by an inpercievable 1%. Then I hit done. Preview looked crisp again. I copied settings of that image. Then I highlighted all other blurry previews and pasted settings and they all became crisp again. Probabley just a quick fix that doesn't solve the problem but my knowledge is limited.

Preview opens up blurry..

I noticed this a few months back but since it's not a "crucial" issue I didn't bother posting but I'm just wondering if anyone knows or if anyone else is experiencing Preview opening up images blurry at first & then you have to manually resize the image in order for it to become sharp again.

Does this happen with all images?
I have noticed that Preview opens images blurry on my computer but they go sharp in a couple of seconds after opening. Have you tried deleting the com.apple.preview.plist file in /Users/<<UserName>>/Library/Preferences?
If you don't feel comfortable deleting the file just move it to the desktop. Then log out and back in and see if you are still getting the same effect.
Hope this helps

Blurry iPhone 4 Previews for managed photos

There have been some previous posts on related blurry preview topics, but I have some very specific observations which may help, and I'm wondering if anyone
a) has seen this before
b) believes this should be filed as a bug report to Apple.
c) has better suggestions.
I'm using Aperture 3.1.2 currently (though most of the below was observed with 3.1.1) on an iMac i3, running 10.6.6.
I have three cameras from which I import photos into Aperture: iPhone 4, iPhone 3GS, and Canon 5D.
- iPhone 3GS and Canon 5D: no matter whether I import directly into Aperture library (managed) or leave the photo somewhere else (referenced), the previews are sharp (when the original is sharp).
- iPhone 4: when the JPEGs are managed, then they appear blurry. When they are imported as referenced, then they are fine and sharp. This is really obvious if I import the same photo directly into the library first, then copy the JPG somewhere else (say with a different filename), and import that photo again into the same project.... the blurry preview and sharp preview show up side by side.
My import workflow for iPhone's, by the way, is to first use Image Capture to download them to a folder on the local HD, then import from directory using Aperture. The reason why I do this is because, unlike Aperture, Image Capture allows you to delete the original photos after import. For my 5D, I import directly from CF card using Aperture itself.
I have tried the various suggestions posted on the forums for the blurry previews:
o Regenerate Previews - this does nothing
o Rebuild library - this doesn't change anything, and has the added disadvantage of adding a whole bunch of previously deleted folders (or that was in the Trash) into my library.
o Delete Previews, restart Aperture - again nothing.
I also tried to Relocate Masters for those iPhone 4 JPEGs that were imported directly into Aperture library (managed). This doesn't update the preview either.
The only thing that seems to work is to relocate the masters, delete the versions, then to reimport the relocated masters back into Aperture as referenced. However, this deletes all of one's tags, edits, etc....
Blurry previews are extremely frustrating, as it makes it really difficult to quickly triage through lots of photos. Later on, my wife may look at that photo in Browser mode and say, why did you tag that with four stars? Only by displaying in single photo or three-up view can one realize that it was a good sharp photo.
I'm quite annoyed that Apple's own products won't integrate... I like Aperture overall too much to go back to Lightroom, but at the end of the day productivity is what matters.
Thanks very much.

So, I had to reboot my iMac since Aperture was hanging when opening the library. After the reboot, no matter if I try importing by drag and drop to the folder, or by checking and clicking on "Import Checked", the previews are now sharp from the iPhone 4 images.
- In most projects, though, the previews that were not sharp before did not automatically become sharp.
- What is weird is that in one particular project, the iPhone 4 previews did seem to become sharp, but my 5D shots in that project the previews became blurry.
It's getting weirder and weirder, folks!
