Saved Image Quality

Hello all,
I was just wondering if other people have noticed a drop in quality for saved images. Anything I save from Safari or Mail looks terrible once it gets to Photos - blurry and pixelated.
Not sure if there's a fix or not yet.

Update: Oct.5th
For those of you still in the dark about this issue, I discovered it's not a hardware issue as much as an OS one.
I noticed a problem with saving JPG images from either an e-mail attachment or via Safari from my iPod Touch 2nd Gen. The image in the Saved Images folder will render as a pixelated image when you preview it. BUT, when you download the image to your desktop, it appears in its original full size and also sharp in quality. (My example was approximately 1024 x 768 w/ a 300kb size).
I took mine into an Apple store and the Genius Bar tech assistant and I were able to determine that it's because the Touch cannot preview/optimize a downloaded hi-res image with anything that exceeds the 320 x 240 resolution of the iPod. You can test this by saving an image from the web that is around that scale. When you preview it, you should see the image load up very crisp.
He said it's a relatively new problem and that he was hopeful the next firmware update would fix the issue. He was stumped though as to how come the iPhone was able to save images from the web and preview in crisp detail. This apparently is unique to the new iPod Touches.
Either way, since mine was still under warranty I asked for an exchange and he gladly did the transaction.
When I got home and opened up my new one (which had 2.1.1 firmware already installed) I tried saving a hi-res image and unfortunately, encountered the same issue. So it's definitely an OS issue.
Hope this helps clear up any worries or confusion.

Saving images with quality 12 increases size. Why?

A minutely modifyed image saved with quality of 10 maintained its original size (more or less), but saving with a quality of 12 increases size.
I would like to know why?
I'd appreciate your comments.

Because that's how .jpg works. Sizes of less than 10 usually compress your files somewhat, lower numbers resulting in smaller file sizes and more compression, with a corresponding loss of quality. Sizes greater than 10 also use the .jpg compression algorithm, but they choose less compression, and so two pixels that may have been compressed together at compression 10 may now be separated at compression 11 or 12, resulting in a larger file. (But that doesn't imply an increase in the quality, even at 12 there is still a slight decrease in quality in that the .jpg saved version still doesn't exactly represent what you saw on the screen)
The amount of modification to the photo doesn't really matter in how much the space the .jpg compression takes up.

Re-saving a report deteriorates image quality

Hi, when my colleague is saving his report in Report Builder 6i many times, the image on it (a company logo) keeps deteriotating. For example, the white part keeps getting a shade of gray after saving. Currently the temp solution is to reimport the image after everything else is ready and no further changes needed.
Is there a proper way to deal with images in Report 6i so the image quality stays? Many thanks.

If your colleage is using Oracle 11i ERP:
Instead of importing the logo to the report, store the logo as a Document with Data Type = File. You can get to the Documents form in several responsibilities. Once the document is saved to the server, you can add an SQL query to your Data Model to call it.
SELECT flobs.file_data Logo
FROM fnd_lobs flobs,
fnd_documents_vl fdoc
WHERE fdoc.document_id = <your document id>
AND fdoc.media_id = flobs.file_id
AND upper(flobs.file_content_type) like '%IMAGE/%'
In the Layout Model, add a field with Source = Logo.

Does flattening (or saving without layers) compromise the image QUALITY?

I'm saving a large .tiff image with multiple layers, but have no need to access the different layers later on, so my question is simply if I can save the image without layers in order to reduce size, or would that also reduce the image QUALITY?

Flattening merges all the layers and gives it a white background, the layer is then named background and is locked. Whereas merge keeps a transparent background if there is one, the remaining layer is not locked.
A flattened image will crop any image data that falls outside the document area. So technically it does effect the quality. The same as what a crop would do.
However it does not adjust the documents image size.
A merged document leaves the image data outside the document area untouched.
That said, some formats like jpg flatten the file not merge it. As it does not support transparency nor layers. Png does not support layers therefore outer data is cropped. But tiff and psd will keep outer data as both of these formats support transparency and layers. Transparency is required to stop the file from being flattened and layers is required to keep any image data that falls outside the document area from being cropped.

FM9: terrible image quality when saving a .fm page as .htm page...

Hello,
I have several framemaker pages I want to save as html pages.
The problem I have concerns the quality of images...
The images I import have a good quality but once I save the page as .htm, Framemaker automatically resizes it and duplicates the image under another name..
Framemaker may not be the best tool to produce html pages but I also need to produce a PDF version of these pages...:-/
I have tried to import .png files, .jpeg files but everytime the result is as bad as before in the .html version..
So far the only solution I have found is to use Dreamweaver to resize the images by hand but it may become a tedious work since I have a lot of images....
Do you have an idea how to obtain a good image quality result in .html?
Do you think I am not using the appropriate tool to do this?
Thank you very much in advance
Anna

Anna,
FM's html export is quite simplistic and lacks many controls.
If you need to get good html from FM, then consider using Omni Systems mif2go (see: http://www.omsys.com/dcl/mif2gopg.htm ). It can be set to use the original import files so no unintended conversions take place. Once you've configured the settings to your liking, it's a simple click and convert for production use. The evaluation version is fully functional and doesn't time out - it just does some random word shuffling so the output wouldn't be usable as a reliable reference.

Losing Image quality when saving to JPeg and posting on line! Please Help.

Hi,
I recently got a new computer. I use CS3 to edit. For some reason, whenever I resize the image, save it as a Jpeg and post it to the web, it loses image quality. Severely. I've never had this problem before....until this new computer.
I usually resize the image to 800, then simply click on Save as Jpeg. Once I resize, it looks fine CS3, but NOT online.
Just a picture of my kid. No critiques please! : )

For blog software, you will have to look under Manage under your admin account. There's an option to define the maximum image size for previews (inline images) and medium image sizes. if they are set to samll, the software will resize them, yet the theme you use may scale them up again to full column width, so they look mooshy. Make sure the image size in the settings panel matches the images you upload. For Facebook it may be similar, but I won't rule out that eitehr of the two services frcibly will change your images to save bandwidth. This should be stated in their terms of use somewhere. If you're merely referring to color shifts, you may wish to check your default color settings and the Embed color profile and Preserve RGB options in the Save for web and Devices dialog.

MIssing image quality warning!? (yellow triangle !)

so in photo 10, when adding low quality / low resolution images to my books or calendars, i used to get a yellow triangle warning me that the quality is not good enough. i also got the warning when enlarging a photo beyond a certain point.
since upgrading to iphoto 11, i can NEVER get this warning to show up?
even when i place obviously low quality / low resolution images, and i enlarge them, I don't see that icon?! no matter what i do, the icon doesn't come up!
has Apple removed this warning? does everyone have it except me? is it an option to turn on and off? this is driving me crazy!

I just spent a week creating my annual family calendar in iPhoto '11, didn't see the yellow low-quality image warning triangles from past iPhoto versions and assumed all the photos were decent enough to publish. Boy was I wrong. When I went to order the calendars, during the assembly process I kept getting low-quality image messages, but it only gave the name of the photo file and stopped processing at that page. It didn't show me what photo it was, so I had to figure out which image it was by using "spotlight" and entering the file name. What a pain in the ***.
Once I fixed the offending image, I had to start the entire order process over again, reconfirm payment and shipment information, only to keep getting a low-quality image error message again, and again, and again. It couldn't have saved all the poor-quality images messages for 1 message, so I could fix all the problematic images at once and only have to resubmit the order once. No, it only told me image by image, page by page, if there was a problem, causing me to have to resubmit my order 7 times. It took me 45 minutes to finally order my calendar. I am not happy. I've been ordering my calendars through iPhoto since 2008 and have never had this much difficulty with image-quality messages and order processing.
The photos that caused the error messages were those that other people had sent me that weren't very good quality, and that I had edited once placed in the calendar. Once I deleted the edited version and replaced with the original version, I didn't get an error message. If the image was just too poor quality to begin with and I couldn't use the edited version, then I replaced it altogether.
I just don't know if anyone else has had this much trouble with uploading and ordering their calendars. I hope Apple reinstates the low-quality image warning system that tells us BEFORE we try to place an order which images may have problems. Or at least just give us ONE error message after assembling the calendar that includes ALL the offending images (including the thumbnails, not just the file names), so we don't have to go back over and over and over again and have the ordering process be so incredibly frustrating.

How to export a fireworks file to flash while retaining image quality?

I created a banner for our website using fireworks cs3. Part of the banner has aimation (basically a slide show of 6 photos). I've tried to export the files by saving the frams to files, but when I do this, the image quality really gets bad. When I try to change the export settings and change the dither, everything but the last frame looks better and the last frame looks like a yellow color is splattered all over it....I've tried just saving the file as an .swf file but when I do so, the file doesn't work when I insert it into my web page, it doesn't work. Is there a better way to do this? Can I export as something else then import into flash and still retain my image quality? Thanks for any input and help!

How are you inserting the file?
Flash objects need to be placed in an object tag...as described here: http://kb2.adobe.com/cps/415/tn_4150.html

Image quality bad in Web Gallery

I used the .Mac web gallery feature for the first time yesterday with images that I had edited in Lightroom and then exported to iPhoto for upload, I chose the jpeg compression at highest quality (they were RAW files taken with my Canon 40D) and saved as sRGB optimized for the web. The thumbnails look fine, but the images look absolutely horrible full screen...focus looks blurry and artifacts in some of the shots. Granted, I'm viewing on my 24" screen and it does look better on my other half's 13" MacBook, but still...the image quality should not suffer like this. I can't believe Apple would release a product the renders such poor quality photos.
Is there something that I'm missing here? Is anyone else noticing this with their web galleries?

Dave:
You can replace the 800 x 600 files with your full sized image files. But it would be a manual operation. Each photo in an web gallery has it's own folder with several versions of the file in it. They are located in the iDisk/Sites/Web/_gallery folder. The file titled web.jpg is used for the slideshow. If you replace it with the original file that's been renamed web.jpg, it will be the one used to display in the slideshow.
HOWEVER, the full sized image file takes a very long time to load when playing the slideshow. If you do that you should use an image resizing application like Resize! to reduce the file size by selecting a higher jpeg compression ( lower quality level) while keeping the pixel dimensions the same. With a 60% quality level and keeping the pixel dimensions the same I reduced a 2816 x 2112 pixel, 2.11 MB image file to 695 KB. The 2.1 MB file took 6 seconds to load, the 695 took 2 seconds and the iPhoto produced file were nearly instantaneous. Resizing down wot 1200 x 900 at 60% reduced the size down to 132 KB, much more manageable for loading and rendering online.
So you would have to test to see what pixel dimension and quality level would work best for you. But keep in mind that you'd have to manually change each file, rename it to web.jpg and copy up to the iDisk.
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 created an Automator workflow application (requires Tiger), 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. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Image quality in iMovie

Hi guys,
I am trying to use iMovie to put together a slide show (I am a wildlife photographer) and it seems great for the job
There are a couple of bugs within iMovie itself but mostly no big deal, except for one that is bugging me.
The images I have generated are perfect quality when viewed in Adobe Lightroom, iPhoto or any other app, but in iMovie there appear to be far fewer colours so that (for example) the sky in an image is heavily pixelated. I can only guess there are fewer colours in the image.
I am confused because in one of the articles I read it claimed that iMovie was directly accessing the file on disk.
I simply dragged and dropped the hi-res images (they are all between 5 and 15 meg size) into iMovie.
Has anyone else come across this? How can I make the images in iMovie look proper so that I can export the

Are our events all co-mingled? Since ownership is ignored I assume we can see each other's video clips? This seems pretty messy to me and prevents any sort of privacy. In fact this basically breaks the whole user model.
Since still images are not stored as an event in iMovie '08, adding an image from iPhoto, your desktop, etc. adds a copy of the file to you project to serve as the "source" for later export of your project. In addition, since there is a maximum size associated with your project, this "stored" image may be scaled if the original height is greater than 1080 pixels. Therefore, my recommendation was to actually look at the "stored, scaled" file in your project so as to compare it with your original files to see there there was any loss in image quality. You can manually open the project "package" using the "contextual" menu option "Show Package Contents" at the Finder level.
I opened it in iMovie but can't see that option nor an option for setting colours to millions (which would probably solve my problem).
The ideal here is to open the file stored in your project and look at it in the QT Player for comparison with the original file. When I said "color depth should be millions," I was referring to the color depth you should find in the inspector window when you open the files in the QT player. Both should normally read "millions" unless you saved them otherwise.

Quicktime image quality problems in FCP

I'm trying to do a basic video tutorial on how to use a tool on my website. I captured the movie from my screen with a product called SnapZpro which saved the movie as a QuickTime movie. However when I import it into FCP to do some mixing with other graphical elements, add some transitions, edit the audio and add some other screen shots, the image quality is awful. I have rendered the file & also exported with no compression and still no luck. The original QT movie capture is crystal clear. Any ideas on how to get the original quality or other ideas on good ways to create a tutorial where a fair amount of editing needs to be done?
Thanks,
Ed

You can spend several productive hours using the search function. We see this topic and variations often. Try searching for SnapzPro, tutorial, screen capture, stuff like that.
We don't know what your movie settings were for your captures using SnapZ nor do we know your sequence settings within FCP. The most likely explanation is that there are some dramatic changes between the two. Your SnapZ clip is being scaled to fit the timeline and this can have a severe resolution compromise.

Trouble drawing on saved images in whiteboard, please help!

I use the Image.IO.write(image,"png",file) method to save my whiteboard drawings onto a file and it displays fine when I import it. But when I draw on it it seems some of my whiteboard buttons are "blending in" with the drawing area where the image is. I guess a way to imagine is there is a row of buttons then a panel containing the image. When I draw on the image area the image of the bottons above are mixed in and everything looks bad. Any idea what I am doing wrong in saving the image? thanks!

Yes, I see the big ugly squares. They are what appears whenever extremely heavy JPEG compression is applied to a low-resolution image tht has relatively large areas of similar colors. Something somewhere is applying such compression to the pages, or portions of them, that you are viewing in your browser(s). Your MBP is not doing that: it can't. Either the page images (or parts of them) are being compressed by the website owners or, if every web page is affected, they are being compressed by your ISP in the process of being transmitted to you, as Gordito suggests. That would greatly increase the speed of page loading, but at the expense of image quality. You wouldn't see the image degradation on an iPhone or cell phone — the screen is too small — but on the MBP's high-resolution display it would be much more apparent, IF the MBP were receiving the signal in the same highly compressed form as the phone. If the MBP receives the same web pages through an ISP that doesn't over-compress them, they'll look the way they ought to look. So if you are receiving these web pages through a cellular ISP rather than through a broadband connection, take the MBP to a wifi hotspot and connect through wifi instead. I bet things will look different then.
Compressing images is something a web browser can't do: a browser just displays the signal that comes to it.

How to prevent PDF presets to alter image quality

In experimenting with various PDF presets, I noticed that with grayscale images in Photoshop, saving as PDFs using different presets, alters image quality, specifically the contrast.
Therefore, it seems like saving an image in the "wrong" PDF preset could undo a lot of prepress work. Is there a better way/format?
To get a crude idea: there is an 8.7% decrease in the percent black between 10% and 50% values (the range) on a step wedge between the original in Photoshop and the HighQuality PDF, which showed the same values, and the PDF/X-1a, which compressed the range by 4 percentage points (approximately a 8.7% decrease).
A visual, and idiosyncratic, assessment of four versions of the same image (Photoshop grayscale, High Qualtiy PDF, PDF/X-1a, and PDF/X-3), which included a step wedge and color ramp, would rank the fidelity to the original from best, HighQuality, to worst, PDF/X-1a.
The same grayscale image in Photoshop CS6 was distilled (File > Print > Adobe PDF) to PDFs using unmodified PDF presets in Acrobat XI distiller.
The following composit screen shot (all four images on the screen, screen print, reorganizing them, then reducing the image to a 120 dpi at 4.2" wide (including text) gives some idea of the differences, but a lot got lost getting it here.

I do a lot of work with print-on-demand books (design and formatting), and I am active on the CreateSpace (the p-o-d division of Amazon.com). Although CS will accept work in virtually any PDF preset or origin (doPDF, cutePDF, etc.), PDF/X-1a is the recommended format, and for other companies it is the only accepted preset.
Here is the dumb question:
On the monitor (as the screen shot shows) the four images (PS, HQ PDF, PDF/X-1a, PDF/X-4) appear quite different: i.e. my video/monitor system is representing the images differently.
A screen shot of all four images on the screen at the same time, then with the info window open in Photoshop, I assessed their CMYK values in the exact same places on each image (lining the images up, using the measure tool and guidelines, measuring at high magnification); here (the color original followed by the original grayscalse conversion) are the black values (C00 M00 Y00 K1-100):
The images display differently, and those displays measure differently.
When I view the PDF images, they appear differently, but if i measure them (Output Preview set to Dot Gain 20%) the K values are the same.
When the same image is prepared using different PDF presets (a previous set of test using different images and looking for something different) they will print (printed in a black & white book by CreateSpace) differently.
How can one predict how a grayscale image will print? How can one prepare it and safely convert it to PDF?

Poor image quality for uncompressed .jpg files

Hello,
I am importing in uncompressed .jpg files that I have made
smaller in Photoshop, but didn't modify compression. This is the
original format at they are stock photos. My project preferences
for jpg files are set to 100. When I import them and publish my
project, the image quality is sub- standard where areas of the
picture are blurry and fadded.
Since the images started as jpg files, recompressing them or
saving them as bmp files which Captivate likes, is not an option.
Any help is greatly appreciated.
Lisa Forman

Hi Rick,
I didn't notice the slide property dialog that is set to
default to Standard. This should help. thanks.
By the way, I am still having major problems with the issue I
emailed you directly last week with all the attachment files. I
know you are busy, but if you have time to revisit, I'd appreciate
it. I don' t have a solution and need to deliver next week.

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?
