Zoom effect, poor image quality

Hi,
I'm trying to zoom an image on rollover, but the quality of
the image gets really bad on zooming (even with 120% zoom). Is
there any way by which I can make the images look better on
zooming? Btw the image I'm using is of type PNG, with a transparent
background.
Thanks!

Hi,
Tried enabling smoothing for that graphic?

Aperture Light Table - Poor image quality

I am using the Light Table function in Aperture (3.4.5.) and I had an issue with the quality of the images on it, when zoomed in or scaled to fit.
The quality of the (larger spread) images looks poor. As if I zoomed in on a thumbnail.
I was looking for a discussion on this and saw some (archived) threads. None of them solved.
However, I think I have found a workaround.
If you get this situation, you can select the image(s) on the light table and regenerate the preview.
Option-click Menu => Photos => Generate Previews
(note: if you don't use the Option key, you will get Menu => Photos => Update Previews and Aperture may say (unjust) that the preview is already up-to-date).
That solves the poor image quality look.

I just remade the same book - as a test - in the extra large hardback format (ie. the one I used for the previous publication, last year).
This time, the pictures are fine. The images appear to be the same quality in the PDF as the originals - much, much better. The size of the file has increased massively too > up from just 2.6MB to 52.8MB.
So does the books production function work well only with the biggest, most expensive option?
I'd really appreciate some feedback from anyone who's tried the different sizes, and preferably some brilliant ideas to make them all work equally well.

HT201335 Airplay Mirror Poor Image Quality on CBS app - help?

Airplay mirror from iMac/iPad to HD TV w/Apple TV has a Poor Image Quality when watching network shows via for example the CBS.com site or the CBS app. The image looks dark, not HD at all. My internet speed/performance is obviously not the issue because Hulu, Netflix etc all come in great using Apple TV ~ sorry, not all that savvy in this department, is the poor picture down to it just being a mirror of the iMac or iPad or is there a setting or something I am missing?

You should use the Acrobat extra menu in word 2010: then edit Preferences and choose Conversion settings : High quality print
Hope it helps

Has anyone had issues with poor image quality when using lightroom to process raw images from Canon 7dmk2

Hi everyone..
..I have been having image quality issues when using Lightroom to process raw files from a 7d mk2... They are all soft with poor clarity.....tonight in despair I tried processing them using canon's software and they are totally different..."much better"
anyone else had similar problems....Andy

I have a 7D2 and have not had what I interpret as poor image quality that has anything to do with the camera.
Can you post a screenshot of what you’re seeing and what specifically you don’t like? Maybe there is something you can do differently or at least there may be an explanation for what you’re seeing.
And if you have a raw image that you wouldn’t mind sharing in a public forum, upload to http://www.dropbox.com/ then post a public share link to it in a reply, here.
In other words post a screenshot of what you see in LR, another of what you see using DPP, and a link to the raw file you’re processing.

Poor image quality save for web

It doesn't matter whether i'm exporting from Ai or Ps or whether it's CS6 or CC. I have changed the raster settings in Ai and i've also tried all optimization options with all different export file types (jpg, png, gif) at all different quality settings. It doesn't matter if I start with an ai, eps, pdf, png... the export result is always poor quality.
I have tried exporting at 300ppi and that does fix the quality issue and bloats the file size, but this way (the export route) is so time consuming since you have to resize your artwork each time as well as the artboard so that it doesn't cut off pixels. Save for web never used to have these quality issues and it also never used to cut off pixels around the edges. These workarounds prove very time consuming and produce file sizes that are not ideal.
When i first noticed this issue I was using Mavericks with CS6 and since am using Yosemite and Creative Cloud.
Steps to reproduce:
1. Create any bitmap or vector graphic in Ai or Ps, It doesn't matter whether you convert text to outlines or not
2. Save for web
3. View image in any application or browser to see poor quality and pixel trimming. Others running the same version and system are not having this issue, but I have checked many forums and found many others that do have this same issue but can't seem to find a solution.
Results:stair stepping, degradation, pixel trimming, general poor image quality
Expected results: Previously the save for web feature allowed for a decent quality image

First try the Cleaner. here's the link for CC but there exists one for Cs6 as well Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
Everything I have read says that you kind of have to compromise file-size for quality. Could you post a screenshot of your settings?
also, if it helps: Creative Suite * Optimizing images

I thought of that too so I tested on another machine with retina display and the file i saved on my machine looked bad on my machine and on the other comparable machine/display. So I sent them the original vector ai file and watched while they saved it the exact same way on their machine and the file looked fine on both of our machines/displays.
All of the settings they used appeared the same as what I used but with different results. I don't recall changing anything but does anyone know if there is some setting that could have been changed that is causing this issue?

Really poor image quality when watching DVDs

Hi,
I was just wondering whether anybody else has experienced really poor image quality whilst watching DVDs on their MacBook? For me, the image is really grainy or blurry. I am pretty sure it cannot be the DVDs as this problem is happening with every film I watch!
Is this a common problem? What can be done (if anything) to resolve this?
Many thanks,
John

Hi John,
open system preference>display, and check if your color depth is in millions color.
try other dvd player like VLC for mac:

Good Luck.

Poor Image Quality on Finished Project

I've seen similar questions before, but no responses. I put together a movie using still pictures, titles, and audio from iTunes using iMovie. I then export it to a .m4v format and import it into iDVD (the newest version). It looks perfect when I view it on my computer, but when I burn it (which works as it should), I get very poor image quality watching it on my TV. The images have red shadows that stretch and cover the faces. Some of the pictures are just more red than they should be, but others are just terrible. Even using the highest quality encoding, the problem persists. PLEASE HELP. Thank you.

Hi
a. make a DiskImage first and test this with Apple DVD-player.
(File menu and down "Make a DiskImage")
b. I only use streamingDV - no .m4v or like (may be it works - I don't know)

Poor image quality when sending via Mail?

This is a new problem for me, yet I'm doing the same thing I always have... Previously, I could "Email" from iPhoto, select an image quality and size, and have it appear correctly as an attachment in a new message, with appropriate quality, with a subject to the effect of "1 Great iPhoto".
Now, however, regardless of the quality/size level I select, I get a small, pixellated, poor quality image attached with a non-sensical subject like cscp_W149.
Any idea what's going on?
Thanks

you are doing it wrong and selecting the thumbnail
THere are many correct ways to email photos with iPhoto - none of them involve going into the iPhoto library and mucking around (which can corrupt your library and cause you to lose data)
The easiest way is to select the photo(s) in iPhoto and click on the mail icon in the toolbar - if it is not there go to the view window and under the shoe in toolbar command check mail
THere are other ways discussed by Terence Devlin in his post in this thread - http://discussions.apple.com/thread.jspa?threadID=1371662&tstart=15

Very Poor Image Quality In Viewer, JPEG Artifacts

I upgraded to Aperture 3 some time ago, and purchased a new Mac Pro specifically for this application. I am an amature/ sometime professional photographer and I have been using Aperture since Version 1. This weekend I finally had some time to sit down with Aperture 3 for some serious work with my scanned film images. These are large TIF masters scanned in with my Nikon CoolScan 9000. Some are medium format black & white Tri-X Pan images, others are 35mm, also black & white Tri-X Pan. Everything scanned in on the Nikon is at the maximum resolution for the master, on the theory that I can always bump it down later if that's necessary.
I am noticing vastly lower image quality in the viewer then with Aperture 2. Specifically, I am seeing massive JPEG artifacts in the viewer image then I have ever seen before. The images also render darker in the viewer then before. These artifacts do not appear when I export my images (say as JPEGS for posting to a web page), or when I print them. The quality of the exported and print images seem just fine and the exported JPEGS are completely free of the artifacts I am seeing in the viewer.
I have tried rebuilding the previews several times, experimenting with different quality settings. I have experimented with different proof profile settings. My printer is an Epson Stylus Photo R1800 and I have tried various paper settings for it as well as other proof profile settings such as the Adobe and Apple RGB settings and the generic grey profiles. Every time I change a setting I have forced a rebuild of the previews to no detectable effect. Nothing I do seems to have any effect whatsoever on the image quality in the viewer which remains relentlessly the same as it always was.
This poor viewer image quality is making it very difficult to work in Aperture 3. I suspect there is a setting somewhere like an easter egg in this new Aperture I haven't found yet but it is becoming very frustraiting and I could use a pointer because, again, nothing I have tried has changed the image quality in the viewer in any way I can detect and the photos look perfectly awful there...darker and loaded with JPEG artifacts. Things export and print just fine, but I need to see what I am going to get in the viewer or I can't do my work.

I interpret this as ... Eventually you should be looking at the Master with the Version changes applied. I'm assuming at this point, you aren't looking at the Preview. Since you don't need Previews to view and edit your images.
Yeah...that's sort of what I gleaned from that text. I was experimenting with the preview settings because I couldn't see any other way to fix the problem. What I'm hearing now is that the problem has no fix. If you scan in black & white film negatives (or anything else that's monochrome I suppose) with the color space set as gray scale you are asking for trouble. The sense I get from the text Gomez Addams referred me to is the behavior in that case is unpredictable, and furthermore film photographers aren't the customer base Apple is trying to cultivate with this product.
Aperture is designed to work with images from digital cameras which use an RGB color space...
Okay...fine. I have several digital cameras I occasionally use for professional work and I am here to tell you Aperture is an absolute blessing for that work. I do shoots every now and then for a local community newspaper and I would not want to live without this product. I remember back when I was a teenager in the 70s being up all night in the darkroom to get an assignment I'd had to cover right before deadline, and then go to my day job the next morning without any sleep. This is much better. And even with the personal art photography it is good to be able to just scan things in and make adjustments in the computer. You can do so much more. I would not want to go back.
But I reckon I need to find something I can rely on for my film work, or at least my black & white film work because as I read this Apple is not supporting film photography with this product and black & white film photography in particular and some of us still use film. No...scanning in my Tri-X negatives in the CoolScan as color produces weird results and anyway Photoshop and GIMP for goodness sakes seem to handle grayscale files just fine. Plus, I've already got thousands of those negatives scanned, I am not rescanning all that in RGB just to satisfy Aperture. The color slide film scans don't seem to be a problem, but that's now. I think I'm being told not to count on That always being the case either.
Aperture is designed to work with images from digital cameras...
Okay...fine...film is old technology after all, Nikon isn't even making their film scanners anymore...check the prices on the few still new-in-the-box ones left out there. My CoolScan 9000 is selling for twice on the second-hand market what I paid for it new and new it wasn't cheap. And yet it's not economically viable for Nikon to continue making them. Film is dying. But I still like working with film and film cameras and I reckon I'll keep doing that until I can't get any more of it and my stash of Tri-X Pan bulk rolls runs out.
Thank you all very much for your help. I think I see what I need to do now.

Poor Image Quality when Printing PDF from Office 07 using Acrobat 9 Pro Ext

Hi there,
Hoping to figure out why my images (jpegs, gifs, pngs, etc) seem to print in very poor quality when printing from Powerpoint and Word 2007?
When I actually print out the pdf onto paper, the images seem fine. The image quality is also good in Word and Excel
I did not have this problem using Office 2003 products.
Is this a common problem? I realize that the problem maybe Office related but any help or information appreciated.
Thanks

If the images' file format is PNG or TIFF you could play with the compression settings available in Acrobat's Preferences.
Edit > Preferences > select the Category "Convert to PDF".
In the"Converting To PDF" pane, select PNG or TIFF.
Then, click on the Edit Settings" button.
For either image format you could try one of the Lossless compression routines.
Be well...

Poor image quality? Why do Jpeg's look so bad?

If anyone has tips on how to improve the image quality of jpeg's in acrobat.com I'd really like to hear them. I've edited the images in Photoshop (CS4), exported them as jpeg's, and inserted them into my acrobat.com presentation. They look horrible, and there are many artifacts. If I insert the same image into Powerpoint, they look considerably better, but I'd prefer not to have to use it. Is there an image quality setting that I'm missing?
Thanks for any help,
Rob

Hi Rob,
Thanks for posting - and sorry you're having trouble. It sounds as though the image's quality is suffering because it's being down-sized upon insertion. In Presentations, any images larger than 1024 on a side are resized to fit within a 1024 bounds (we do this to optimize performance - important for a web application).
Here are some tips from one of our fine engineers:
For the best looking images, pre-scale your images to fit the size of the presentation before you upload them; for reference, the slide canvas is 720 pixels wide and 540 pixels tall. Any image larger than those dimensions is larger than it needs to be on the client so you and your audience are downloading more data than they will ever see. If you resize your images to fit the size it will appear on the screen, you will have a better looking image.
The choice of image format makes a difference at this scale as well. For image with smooth transitions like photographs of landscapes, jpeg is a good format. For computer generated diagrams like charts, or images with lots of details like text, PNG is a better format.
It is important that the image be scaled to the appropriate size before uploading because the server will recompress any image it needs to scale using JPEG compression. So if you are uploading a PNG image with transparency, you will loose any transparency effect if the image is large enough to require scaling on the server.
I hope this is helpful, Rob. Please let us know if you have any further questions.
Best regards,
Rebecca

Poor image quality using iMovie 8 or iDVD after importing DV file via FW

Hello,
i am a complete newby and asking for help. I have bought a Panasonic NV-GS320EG-S miniDV Camcorder. First i connected it via S-Video to my Pioneer Plasma which worked fine.
I have connected the camcorder via Firewire to my iMac 20/2,4 GHz, camcorder will launch import window, streaming works but in iMovie the image quality is already rather poor. I can cut files and all but after using Import film and burning it with latest Toast, picture quality is even worse, that means colors are natural but no sharpness, lots of shivering lines as soon as the angle is moving.
I've tried to import directly into iDVD with the direct transfer function for Firewire which works technically as well but the result is mainly the same, when i burn the DVD the picture quality gets far worse than via S-Video connection.
Last thing i tried is importing to iMovie, importing for media browser and reopening file in iDVD which burns the DVD later, all that works technically fine, but the image result remains absolutely poor, my wife meant inacceptable...
Any ideas what that could be??? I've always imported and exported the film with the largest picture mode possible...

I am using the Panasonic HDC-SD5 camcorder which records in AVCHD.
I also have a JVC miniDV camcorder.
The following is available in iMovie 08 help:If the larger sizes are not available, the original project media isn’t large enough to render in that size. The largest media size used in the project determines the final movie sizes you can render.
Tiny: Always 176 by 144 pixels.
Mobile: Always 480 by 272 pixels.
Medium: Varies in size from 640 by 480 pixels (standard aspect ratio) to 640 by 360 pixels (widescreen), depending on the size of the media in your project.
Large: Always 960 by 540 pixels (widescreen). No large size is rendered if your original video isn’t high definition (HD).

Poor image quality on computer

I recently completed a short film in FCE and burned it to DVD using iDVD (7.0.4) set to Professional Quality. When the DVD is played back on my TV it looks fine. However when I play it on my iMac the image quality is rather poor (very grainy, pixelated), particularly when played full-screen. Any thoughts? Thanks in advance for any replies.

Hi
Nothing wrong with that.
• There are NO HD version of iDVD up till NOW
• Your iMac screen has a at least 4 to 5 times Greater resolution
• On the DVD there is SD (old TV quality resolution) and that's what's playbacked
• One can do a few things to get as much possibly from iDVD and from FCE/P
I do - from FinalCut E/P
• Export out as a QuickTime .mov file
• Not Selfcontained - not important but saves time and space
• NO QUICKTIME CONVERSION - Important
• I use Verbatim DVD-R in iDVD
• I set down burn speed to x4 or x1
• I use Pro Encoding Quality
• I secure a minimum of 25Gb free space on internal boot/start-up hard disk
(iDVD can't use space on others - AT ALL)

Poor image quality on exported version

I am trying to export versions of my photos to a folder on my external drive. Every time I do this the resulting jpg is washed out and has poor resolution + a ton of noise. The resulting image is substantially lighter than the images in my aperture window, yet the histogram does not indicate that the images should be that light or washed out.
The images are all starting as RAW images. The export settings are for image quality 12, 300 dpi, sRGB, original jpg. I have onscreen proofing turned on and set to sRGB. My print lab said that the image quality could be 10, but when they looked so horrible I bumped them up.
I had Aperture for a long time before upgrading to Aperture 2 in March. From March to August I did not have any problems, so this is a more recent problem. I have not yet upgraded to Snow Leopard. Please help!!! Thanks!!!
