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

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.

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

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.

Poor image quality with 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

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?

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)

*Not knowing the origin to Your problem - General approach when in trouble is as follows.*
• Free space on internal (start-up) hard disk if it is less than 10Gb should rather have 25Gb
• Hard disk is untidy. Repair Permissions, Repair Hard disk (Apple Disc Util tool)
• Delete iDVD pref file - *or rather start a new user/account* - log into this and re-try
iDVD pref file resides. Mac Hard Disk (start-up HD)/Users/"Your account"/Library/Preferences and is named.
com.apple.iDVD.plist
While iDVD is NOT RUNNING - move this file out to desk-top.
Now restart iDVD.
• Program miss-match. iDVD 5.0.2, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK - DON’T work under Leopard
• Program miss-match. iDVD 6.0.4, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK (might work under Leopard)
• Program miss-match. iDVD’08 v. 7.0.1, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK (might work under Leopard)
• iDVD (08) v7 Locate theme folder. Move out iDVD1, iDVD 2 and eventually iDVD4 folders to desktop - re-try
• Try a Cleaning CD/DVD that cleans the laser lens on the DVD burner/player
iDVD 6.0.4 and iDVD 7.0.1 are compatible with Mac OS X 10.5 Leopard
Last resort. from Craig. Solved the problem!! Finally!!
I deleted every iDVD application and folder from my boot drive,
emptied the trash and then installed iDVD 08 using the customize option
and I am up and running.
If You do a re-install be sure to get rid of all iDVD old parts AND then EMPTY the Trash-basket !

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.

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?

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.

Why am I getting poor image quality on PowerPoint notes pages?

Hi,
I am using Acrobat Pro version 9, pre-Lion. I have upgraded to Lion, but have this problem before Lion.
When printing slides from a PowerPoint presentation, and choosing the standard "Save as Adobe PDF" option, the image quality on the output is perfect. If, however, I do the same thing but try to print the notes pages, the image gets pixelated.
I searched the Microsoft site for help, and all I could find is a recommendation to use PNG images in my PowerPoint, which I am indeed using.
Any ideas? Thanks....

Lion should not cause the blacks to print faded. The printer drivers used by Snow Leopard and Leopard are the same version as that used by Lion.
For starters I suggest you check that you have the latest version installed. This Apple KB article shows the MG6100 series has v10.51.2.0 as the latest version.
I also recommend you do a Nozzle test print. This can be executed from the MG6120 control panel or via the Printer Utilties window (via Print & Scan, select the printer and then open Options & Supplies and then select the Utilties tab).
If the nozzle test print is okay but the blacks still look faded when printing photos (note the printer has two black ink tanks - one for photos and one for text) then try a reset of the printing system. This will remove the MG6120 from the Print & Scan pane but not the supporting drivers. So you will only have to add the printer again.

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...

Aperture 1.5.3 and iWeb - poor image quality and shuffled Media browser

Hi, I have two questions:
1. I used to use iPhoto 6 together with iWeb 1.1.2, but have since upgraded to Aperture. My Aperture library previews show up nicely in iWeb's media browser, but the quality of the thumbs on the photopage I create, and fullsize images in iWeb's slideshow look really bad and pixelated compared to when I used the exact same images from my iPhoto 6 Library. How can this be? I have set the preview size in Aperture to 1280 x 1280 and quality to 5. Does that have something to do with the poor quality?
2. The Media browser in iWeb completely ignores the dates on the images from the Aperture library, resulting in the images being shuffled completely, making it hard to find the images I want to use. How can that be? Why doesn't it work like when I used iWeb with my iPhoto library?

Poor image quality when importing SWF

I maintain a site for a photographer and as he added more
images the SWF got to be very large, so I split up the site and
used a main page to import the smaller SWF files into a target.
However, I found that all my clean crisp images become dull when
imported but still look sharp in the SWF itself. I tied to find all
the JPEG settings and push them up but still with no luck. Does
anybody have any insight to why this is happening?

Hello micsaint111111111111,
The reason they look more blurry than in the original swf is
that you are
dealing with dual compression from the original swf AND the
swf you are loading
the images into.
The easiest/best way to import your jpgs would be using
LoadMovie to load
the actual jpg files. That keeps all the jpgs separate so
your swf file will
be tiny. Plus the quality will be the same as the original
jpg.
That said- have you gone into your swfs and changed the
default image quality
on each of the images to 90 or 100? You do that in your
library by right-clicking
on the actual images and then going to Properties and
unchecking "Use document
default quality". That is one issue that a lot of people seem
to miss and
it might help if you don't want to recode your Flash with the
LoadMovie method.

Poor image quality -slideshow iDVD-need help asap

Hello
does anybody know how to create a better quality slideshow???? It sim,ply does look totally unprofessional .. when the dvd is burned.
We have supersharp images .. but once the DVD is burned and you pop it back in the unit .. the images look fuzzy .. and not as crisp as when you actually run them in iPhoto, or iDVD...
this is really urgent .. I'd appreciate if somebody give us a hint ... what to do .. or is there an alternative to created 100% quality slideshows on a dvd.
We need to play the burned DVD's on a computer (to show to clients) as well as on a TV .. in case the client wants to view the DVD at home.
please respond to
[email protected]
Thank you!
I understand that it might look fuzzy on a TV screen .. but why does it look so bad on a computer screen? That is not a good way to present work/images .. please help!

Don't count on FCE or DVD Studio Pro to be better. I think your issue is with MPEG-2 compression.
I build my slideshows within iDVD, not iPhoto or iMovie HD. Here's an example:
Ireland 2004 iDVD Project
Nearly 800 images dragged into iDVD as organized folders from the hard drive. Transitions on each image, and menus, sub-menus, and sub-sub menus. The sub-menus are created by clicking on the Folder icon on the iDVD interface.
Main Menu has 6 buttons: Downpatrick, Antrim Coast, Letterkenny, Sligo, Trim, and Extras. Behind each button are additional buttons ranging from 3 to 6 buttons. The Extras button goes fairly deep. When you click on Extras, it gives you 3 choices on a new menu. The "B&Bs" button opens a new menu with 5 buttons. The "Movies" button opens a new menu with 4 buttons. If you click on the "Irish Music" button, you open a new menu with 2 buttons. At that point, you are at a "sub-sub-sub menu."
Music was on 95% of the slideshows. Some movies converted to QT DV from Canon S400 digicam .AVI files (iDVD 4). Now convert to H.264 with QuickTime 7. Images are original 4MP (2MB) JPEG images from the same digicam. This DVD project is around 4GB with all pictures as DVD-ROM content.

Poor Image Quality Transfered To iPhone

Hey guys,
I'm pretty new to aperture after switching from iPhoto and have run into the following problem.
I have iTunes set up to sync certain projects in my library over to my iPhone. The problem is the image quality being transferred is rather low and alot of pictures on my iPhone look grainy/pixelated. If I go into Aperture I can see the file just fine in full quality.
Any tips on how to get the quality transferred to the iPhone better? Thanks

Aperture mainly uses previews for sharing with other applications (so you can use them in iLife/iWork, see them in Finder, easily upload albums to Apple TV via iTunes, etc.). None of these functions work if you don't have previews generated for them.
Given there's a fair bit of space overhead to Previews, and given I found after a year+ of use that I had to manually create previews for what I wanted to see, I found it was easier for me to just do this fully manually and export JPEGs.
But have a read of the Previews section of the Aperture documentation. See how they're described, and see if it's functionality you want. If not, there's no reason you have to use previews at all. I don't.
