Image Quality suddenly reduced

I have a Macbook 2.0 and I just purchased it about 4 weeks ago. I'm new to the Mac OS X but have used PC's all my life and consider myself an advanced user.
I took some pictures with photobooth and imported some off of my digital camera when i first got the notebook. Recently I customized the display because I didn't like the way the screen colors looked. Now in Photobooth and all my old saved files look ALOT worse. The colors look right on other things viewed on the web, and when I get the same picture from my PC it looks good. I was wondering how I can get that old picture quality back. Every image i take with photobooth now looks grainy/slightly washed out.
Is there something I am missing? Does it have to do with Colorsync profiles or something. Can I reset the laptop to how it came without a reformat? Any help would be awesome. Thanks guys and girls.

What is most noticable to me is my profile picture on facebook that is completely pixeled out, and like everything on vimeo looks weird. Especially the smiley logos, the upload a video logo and get facebook connected logo.
If you want me to upload it elsewhere, let me know.

The image quality suddenly downgraded in Photoshop

Hello guys,
today when I'm editing my file as usual, suddenly I found out that the image quality are downgraded inside photoshop
but it become smooth and normal again when I try to blow up the image. The saved image have no trouble as well.
When I'm using general preview size, it will be like this
When I blow up the detail, it become smooth again like this
I'm not sure if I accidentially clicked any button, could anyone help with this please? big thanks!!!

this is windows system and I've checked the image processor box
The text is not rendered into pixels either,
the below is the screen capture:

Image quality suddenly much worse in almost all apps (Visible pixels)

Hi everyone
Suddenly the image quality om my macbook pro started going fubar. I started noticing that everything on facebook looked so bad, and then i started to realize that it was all images/pictures and everything that was bad while browsing. I then tried loading up some HD movies that used to be totally pixel perfect, and now they look pretty bad too(quciktime)
Anyone know what this could be and how to resolve this?

How do l preserve image quality when reducing the size of my brochure for use as a pdf?

l've designed a brochure full of my work, and reduced the size so l can email the final pdf...but my test recipients are saying the images are not sharp...they are too soft.
Can anyone help me preserve image sharpness?

Don't use the resize feature as the images will be changed to 72 dpi. Resize the images BEFORE adding them to Pages. Make them about 200 dpi if they are to be printed. You can have less resolution if the pdf is only for the screen.

Media File Image Quality Suddenly Poor

Hi All,
After a few months I have returned to my FCP activities but for some reason the quality of the files in both the viewer and the canvas now look quite poor. There is some color distortion, a kind of "shimmy" to the video, and generally look like crap. This is with all my media, in all projects. As soon as the clip is stopped it seems to become focused, as a still. Yet, videos outside of FCP look fine.
Any thoughts?
Thanks in advance!

Is the footage stored on the exact same drives as before? Or on different drives? How are the drives connected?
Upgrade FCP since the projects were done?
Might just need to trash your prefs. I feel another stock answer coming out.... BAM!
#44: FCP acting weird - Trash Prefs
Shane's Stock Answer #44: FCP acting weird or unusual. Just not like is normally should
If the program was working fine, and now isn't, or just isn't working the way it should, the first things to do are:
1) Trash your FCP preferences. Download the Preference Manager from Digital Rebellion: http://www.digitalrebellion.com/pref_man.htm
http://www.kenstone.net/fcphomepage/trashing_fcpprefs.html
2) Open the Disk Utility and Repair Permissions.
3) Shut down for 10 min. Go for a quick walk around the block and get SOME exercise today. Come back, turn on the computer and see how things are.
4) (optional) Do the Hokey Pokey and turn your self about. Results may vary.

Iphoto 2 reduces image quality on iPad Air

I seems there is a significant reduction in image quality when editing images in iPhoto 2 (iOS7) on an iPad Air.
Not sure which component is the real problem ... and no, I'm not talking about file size (I know they are reduced) - I talk about dpi
So here's my old setup:
Nikon 5000 (image quality fine), iPad 3, Connection Kit for SD card, iPhoto on iOS 6
... with that setup I was able to save my edited pictures back to camera roll and the still had 300 dpi
My current setup:
Nikon 5000 (image quality fine), iPad Air, New Connection Kit for SD card (lightning), iPhoto 2.0 on iOS 7
... now my adited images only save back to the camera roll with 72 dpi!
As my DSLR and the SD cards are the same than before it seems that either
- Connection Kit
- iPhoto 2
- iOS7
- iPad Air
is the trouble maker!
While iPhoto seems the obvious source for the problem I had an experience that makes me think it could also be the iPad Air:
After creating a video with iVideo (with material from the iPhone 5) I saved this bakc to the camera roll and it was resized (resulting in cuts on the left and right edges) on the iPad.
Copying the same Video to iVideo via AirDrop on my iPhone 5 and savicg it to camera roll there resulted in a correct non-resized version.
So while I can easily live with that workaround for Video the reduction in images from 300 dpi to 72 dpi is signifikant and a real problem.
Anybody experiencing the same, any hints what I can do different to avoid thar reduction?

Just found an interesting article that may be the solution of my problem:
http://www.ilounge.com/index.php/articles/comments/icloud-photo-stream-and-image -quality/
As I brought together pictures from my DSLR and the iPhone I think I used the Shared PhotoStream folder for editing them in iPhoto 2. In the past I usually worked on the pictures separately (and directly form the Camera Roll) as I didn't mix so much DSLR and iPhone use.
That should explain it and I have to remember to edit directly in the camera roll and the next time.
So it's not a big deal ... I still have all the originals and will save them somewere in my Dropbox if I need them in higher resolution. At least I know I have to change my re-work behavior in the future.

Sudden Overlay Shift and Drop in Image Quality

I’ve been authoring DVDs for two years now, and operating out of my current authoring lab for 4 months. All of a sudden, with this one project, I’m having a frustrating menu problem.
The symptoms of the problem are:
1. Overlays no longer match up, they’re WAY off, by about %10 of screen size
2. Big drop in image quality of menus, text looks like garbage.
Here’s my workflow for the menus:
1. Create .mov files in After Effects, comp settings D1 720x486, render at lossless
2. Pull into FCP to create audio, render in FCP as 10 Bit Uncompressed, export using compressor at MPEG-2 (DVD Best 90 minutes)
3. Create overlay files in AE, render frames as PSD files
I’ve tried a lot of variations on this tonight, such as exporting .tiff’s from FCP and building the overlay in Photoshop, or using Compressor to encode the .mov’s from AE independent of FCP. The two symptoms are always there. When I pull the raw .mov from AE into DVD Studio Pro, the quality is a little better but the overlays are still off.
Please Help!
<Edited by Moderator>

I Feel your pain guys! The problem is, you are creating the comp in AE with the incorrect Size. I experienced the same problem for months and actually went back and forth between DVDSP and Photoshop until the overlays fit. After extreme headaches I decided to try something different.
Here's my process;
1. start by creating the comp in AE at NTSC D1 Square Pixels (720 X540)
2. complete the animation
3. then on rendering go to the output module and click stretch
4. Select NTSC DV (720 X 480). This will put it down to what you need it to be in DVDSP
5. Then create your overlays at the 720 X 486
6. Import and build your DVD as usual and it should work out
Somehow this seems to trick DVDSP into putting things where they are supposed to be. It may seem dumb and archaic, but it beats going back and forth! I hope it works for you!

Does Export Version reduces image quality?

Hi,
I got smaller file size when I "export version" at "original size". My master was jpeg of 5.1MB and I exported in jpeg format, I got 3.6MB. If I "export master", I do get 5.1MB. What does Aperture do to the jpeg image that reduces the file size?
Then I played around with "image quality", which is 10 by default. If I set it to 11, I got a file of 4.1 MB, still smaller than the original 5.1MB. Set it to 12 I got a file of 10.4MB. I am kind of confused. I guess the "image quality" relates to degree of jpeg compression, and a 12 setting means that Aperture compresses the jpeg image at a lower compression ratio than my camera? Does Aperture uncompress jpeg image and re-compress it when "export version"?
The bottom line is, how do I preserve image quality after adjustments? In other words, I would like to export at the same image quality as my original photo, or as close as possible (I assume Aperture reduces jpeg image quality a bit every time I apply adjustments to the image via export). Thanks much for your time.

2) When I make adjustments in Aperture I actually work on the image Aperture produces out of the master file - which should be about 73MB in my computer memory as the size of the image is 2848 x 4272 and Aperture works in 16 bit.
Internally, Core Image (which Aperture uses) actually works in 32-bit, but your basic idea is right.
3) When I export, Apertures compresses this 73MB image (assume adjustments don't make much difference to the image size) to a jpeg file.
First the image will be reduced to the bit depth of your export preset. Image adjustments will make quite a difference to the final file size because areas of high definition detail and a large tonal range will both increase the file size for a given compression setting. So any sharpening, for example, will increase the file size.
As a test, export an image with no sharpening applied, then add some edge sharpening and export it again. You should see a noticeable difference in file sizes.
Correct?
Pretty much.

Reduce image quality (and file size)

Is there a simple way to reduce the quality of all backgroung
images ? (there are all bitmap images, about 3 MB each of them)
I imagine that by reducing the image quality, the file size
will be less huge...
But I wasn't able to find a way to do that...
(the option about JPEG quality in project/preferences has no
effect, because all background images are bitmap... )
Any idea is welcome !

Hi Valerie
I have been doing some research on this -- the issue of file
size (relating to both .cp and .swf) crops up a lot on this forum,
so I wanted to find out which were the critical factors relating to
images.
My findings show that there are two critical factors:
-- Slide Properties: Quality (High, Standard, JPEG,
Optimized)
-- Format of original image file (used for slide background
or inserted image object)
To summarize the results of my testing:
Slide Quality
Changing the slide quality from High
to Standard or JPEG makes little or no difference to the size of
the .cp file but can *significantly* reduce the size of the
.swf
This is an especially useful way of
dealing with the very large .swf file sizes caused by importing PPT
slides
A .swf consisting entirely of
imported PPT slides with complex backgrounds may be reduced to less
than 10% of its original size by changing the quality setting for
each of the slides to JPEG and using a JPEG image quality setting
of 75%.
Format of original image file
For complex images such as photos,
the best image file format to use is (oddly) .bmp -- although it
results in a larger .cp file than other file formats (such as .jpg
or .png), it generates the smallest .swf output.
The benefit of using the .bmp format
is less marked if you have set slide quality to Standard instead of
High, but it can still cut the file size of the .swf output by up
to 50%
For slides using a quality setting of
JPEG, there appears to be no difference in resulting .swf file size
between .bmp or any other image file format
A final comment: it is interesting to compare the size of the
.cp and resulting .swf for different Captivate projects. There is
typically an assumption that the .swf file will be smaller due to
compression. However, this is not always the case. For example, I
tested one project that used High slide quality and images that had
been inserted from .jpg files -- the generated .swf file was over 4
times larger than the .cp file. However, when I changed the quality
setting for all slides to JPEG, the .swf file reduced to less than
50% of the size of the .cp file.
I hope this information is helpful -- please contact me if
you'd like to see the detailed test data.

PLEASE HELP! 67MG PDF file can't reduce to email without losing image quality

I have created an 88 page fashion look book for work and it needs to be emailed out pronto to our customers!
I created it using In Design (the latest version)
I saved it as a PDF for my records - Highest Quality for printing purposes.
I open it in the latest version of Adobe Acrobat Pro XI - Version 11
When I compress the file it goes form 67Mg down to 10MG which is great, however the image quality is not good enough.
Being a fashion brand we need it to look crystal clear!
Can anyone help me and tell me where I am going wrong???
Thanks you in advance, Nicky

Try working on the images themselves before you create the original document. I don't normally recommend JPeg, but if you have pictures the feature of JPegs that reduces the color sharpness may help. Once you have what you want, you might then change it to a TIFF or PNG file. You can also do an audit in the PDF (save as>PDF Optimize) to see where the bloat is located. It is likely in the images. In that case you need to see how to reduce the size of the original images (actually work on copies so your originals stay good). It may be that you are using too many pixels (300-600 should be good in most cases) or you might be able to reduce the color depth (256 colors might be adequate. When you use the photo in ID, be sure you use it at 100%. If you need to change the size, do it in a graphics package that can properly interpolate the bits. You should do physical size reduction before you reduce the resolution. It may be that what is happening when you do the compression to 10MB is that the interpolation of the pixels is getting in the way. So doing all of this on the graphic before you use it would help a lot. I may not be a graphic expert, but trying to work on the original graphic to size and quality before you use it is typically a first step to a good look. PhotoShop should be able to do the reduction, but a simple program for such is IrfanView.

Why has the image quality of my PNG sequences suddenly worsened?

I've been regularly exporting PNG sequences from Premiere Pro CS6, but suddenly the image quality of the images looks terrible.
All my export settings look correct. Any thoughts on what might be causing this?
Thanks...

...and now the results are very poor...
And in which way exactly? How do you judge on quality?
My ... settings are ... 792x582 (same size as source)... My Preview File Format is the default I-frame only MPEG.
Your frame size is not good for previewing in PrPro. MPEG 2 uses macroblocks of 8x8 pixels for compressing data. And now what you get with your frame size: 792 pix / 8 = 99; 582 pix / 8 = 72.75
My export settings are...

Re: Sudden loss of project image quality in iMovie 11

Hi
I'm an anxious technophobe looking for answers...
The image quality of my iMovie project suddenly went from crisp, to blurry and made the black areas in the film grey and pixilated/blocky (or is it considered 'noise'?). It had been perfectly fine before. The footage was shot on a 2011 Sony Handicam and I'm using a 2011 MacBook Pro. I had recently installed updates, including one that supposed fixed out of synch sound problems. I had a loss of quality with another project and optimised it to "original size" (It took hours and made absolutely no difference BTW). I should also mention my hard drive has limited space at the moment and iMovie is running very slowly.
Any suggestions/ diagnosis???
I am anxious to restore the previous sharp quality I had just hours ago.
Thanks

It sounds like the hard disk space could be the culprit.
I would recommend you get an external drive. You need to move some of your events to the external drive to free up space. This must be done within iMovie. Let us know if you need help with this. (or search the discussions for how to move events)

Does reducing image size reduce image quality?

i 'm new to AI and also to this forum.
I know that enlarging and image can reduce image quality.
I'd like to know if reducing the image size (not in pixels, but in actual size),
will reduce the quality?
i have a Ai file that's 600x300, and need to reduce it to 300x120 my websie.
Before I convert it to a web format, I want to reduce this large Ai file to 300x120.
Will i still lose quality even if it's still an Ai file, before converting to web format???
thanks!!!!!

No it is however best to use save for the web to do so for the best optimization.
keep in mind the only lose in quality will be if some one grabbed it off of the website and tried to enlarge it or view it at a larger display size.
What you want to do is the best way of reducing the size.

!! Exporting SWF file in PDF reduces image quality.

Hello,
I have a file with many multi-state picture frames and buttons for them. I export it in pieces in SWF format, then I put the SWF's back in the document as a new layer and export as interactive PDF. Finally everything worked fine, except that PDF opens in a larger then normal zoom and when zooming in on pictures the quality is very poor I am guessing 72ppi at the intended zoom. I check the SWF file and see that its image quality is good when zoomed, so the problem is with the way the PDF has exported the SWF.
notes: I made sure the settings were to export at 300ppi and high image quality. When I take a single multi-state frame with its associated button and export to SWF then PDF the image quality is maintained.... however I have over 150 image frames, so I rather not export them individually. Please, please reply... any suggestions will be gratefully excepted.

edit your image in photoshop and experiment with various settings/size. there's no magic high quality small file size setting.
it's a trade-off. the higher the quality and the greater the image dimensions, the greater the file size. you have to decide where those are acceptable.

Sudden Change in Image Quality

I recently started using my I Sight for conferencing and was quite pleased with the results / overall image quality it provided. It was fine with the daylight setting of my office almost the entire day, and in the evening with tungsten lighting in the room, it also was great. Bright in all situations and pretty well balanced. Then one day I logged in to a chat and found in the daylight setting where it once was fine... I was now very dark, and later in the evening where I had always had sufficient lighting... it again was very dark. I also noticed a green cast on the back wall and in the skin tones. What can I do to get my I Sight to go back to the way it was??? I tried to white balance with a piece of paper and the black "X" which did nothing and preferences seem to do nothing. Is there anything? Important to note: the change occured entirely on its own... I did nothing... it just happened?????

Hello Scott,
Welcome to Apple Discussions.
Thanks for the thorough explanation of your problem. Well done.
It seems you have already tried the relevant suggestions from the Improving Your iSight Picture FAQ.
If you have ever installed iChatUSBCam or iGlasses, someone may have changed your color and brightness settings. Either of these apps allow manual adjustment of the settings that iSight and iChat AV normally adjust automatically.
If iGlasses or iChatUSBCam settings are not your problem, try to remember any other hardware or software you have changed since your iSight worked correctly. Perhaps you have changed or added something that is causing your strange symptoms. Be sure to include changes in conference backgrounds, room lighting, and decor in addition to possible changes in your computer system. Can these changes be removed, adjusted, or uninstalled?
Once you have ruled out the above, you can check your iSight using the tests and trouble shooting suggestions in the How To Ensure Your iSight Is Functional FAQ. if your iSight fails ALL tests see your Apple VAR or Service Technician to have it checked. It may be damaged. If you do not have local access to qualified Apple Service Technicians, see the iSight Service info links in the Where to Find Help for iSight? FAQ,
By the way, your our system info shows that you are using Mac OS X (10.4). I suggest you apply the Mac OS X Update 10.4.2 Combo ASAP. The 10.4.2 Combo corrects several issues with previous versions of Tiger. I suggest using an update method like How I Update My Mac OS X.
