Bad image quality

Hello,
Since i have upgrade my iphone 3GS from IOS 3 to IOS 5, all my small format images are very pixeliszed (wrong pixels displayed).
Any ideas ?
Thanks a lot.

Yeah the camera isn't that good and, from my experience, Sony isn't going to do anything about it.

10.6.2: Bad image quality with SIPS

I used to convert my PDF documents with SIPS like this:
/usr/bin/sips --setProperty format jpeg --setProperty formatOptions high -z 400 200 sourcefilename.pdf --out targetfilename.jpg
This results in a very bad image quality after updating to 10.6.2 (the text contained in the source pdf file is nearly unreadable in the resulting image, especially when using the -z attribute for downsizing).
I could reconstruct this behaviour with several machines today: when using 10.6.1 the quality is fine, but after the update to 10.6.2 the resulting image quality is unacceptable.
Any ideas? Or could this be a bug? The man page for sips does not contain any information about new parameters and the image quality for other target formats (tif, png, ...) seems to be ok.

That picture looks like it was taken in a dimly lit room.
You could try using night mode but you will need a very steady hand.
Most basic phone cameras just cannot produce good pictures indoors when not in brightly lit areas. LED flashes just cannot do a good enough job when compared to real cameras.
Megapixels don't equal quality, it's the lens and flash that make the biggest difference.

Brand new E7-00, wity *very* bad image quality

Yes I did remove the protective film from the camera cover.
And Yes, I deed clean the glass in front of the camera.
But the 8M camera produces images worse than a 0.1 megapixel webcam!
Is this normal? Anything I can do?
See for a sample:

I haven't touched any of the settings so they all are default values, but I'll list the current setting here anyway:
(my phone switched to Dutch language, and I don't know how to revert it to EN, so I'll try to translate the entries here)
ColorTone: Normal
WhiteBalance: Automatic
Lightening: 0
ISO_A: Automatic
Contrast: shows slider in the middle of range
Sharpness: Normal
Settings:
Imagequality: 6M - 16:9
Record Location: Yes
Show recorded images: Yes
ImageTone (??): Camera1 (I now tried camera1..Camera4, they all look similar)
Use memory: E:MassStorage
And when the camera is active, the information bar on the bottom of the screen shows the flash is set to "A", to the right of that is again an "A" (I suppose the picture type setting).
So as far as I know, everything is set to "Automatic", "normal", or "middle of range".
Also, I don't see a "**bleep** up image quality really bad" option, so whatever the other settings, I wouldn't expect images to be this vague...
Any recommendations?

Really bad image quality when burning

Hi, i am very new at this discussion thing and am a french speaker so hope i do this ansking question ok.
I'm having problems with image quality of my 1h46 min movie imported from imovie (initially from quicktime made from final cut pro). I am having pixelly images when camera is moving... Although have read some things about this on the forum none of the answers seem to resolve my problem.
I have selected best quality in my prefs but with no success. I figure it's a compression / codec problem but i do not have a clue about all this technical stuff. I don't know what next move i should make.
Thanks for any help...

Hi ! Thanx for responding...
In FCP i did choose export DV/NTSC and imported from camera with apple firewire NTSC (720x480). Should i have imported material in (640x480/30fps/interlaced...) ?
I have had this problem with smaller projects of 20 min of video also so i don't think it has to do with size... At the moment i am making a disc image of my dvd on my desktop hoping to burn through Toast. Otherwise i am also thinking about exporting movie from FCP to tape then importing back to iMov through camera...
I'm kind of desperate and don't really know what to do... I'm also gonna start reading compressor 2 and maybe forget about iDVD an d just burn it through toast. Wich is kind of dissapointing cause without interface, menu and all...

Bad image quality of slideshows

I am a new Mac user. I am having difficulty making slideshows from the iLife version 6 software with the features that I want and decent image quality.
I've been trying with iPhoto, iMovieHD and iDVD. I want to be able to put captions or title screens in my slideshows, so I must use either iDVD or iMovieHD. If I do not want my photos to pan and zoom, I can use iDVD. I've done this and burned the result to a DVD. When I play the DVD on my 65" wide screen high definition television, the image quality of the slideshow is not satisfactory. Diagonal lines have visible stepping. Just before a photo transitions to the next photo, there is a noticeable increase in the number of digital artifacts for about one second.
For some slideshows, I wanted to have the pan and zoom effects, and title screens, so I used iMovieHD. When I started the project, I chose the format 1080i because that is what my high definition television can do. I realize, however, that my DVD player cannot do that resolution, so I am not sure that was the correct format to choose. I "shared" the completed slideshow movie to iDVD. When I play that slideshow, I see many digital artifacts in the images as the zoom happens. The images are not as good as looking at the original digital photos on the computer.
Is there a way to make a slideshow on a DVD that has an image quality that matches the original digital photograph? Is it possible to use the pan and zoom effect when I wish to play a DVD slideshow on a television?
Any help is appreciated.
MacBook Pro Mac OS X (10.4.4) 2MB memory, 15"

I realize that I did not ask exactly the right question.
I've made slideshows using U-lead software on my windows XP desktop machine. The image quality of those slideshows on a standard TV is better than what I can do with iDVD and iMovie. So I'm wondering is there something I need to do in iDVD that might be automatically happening in the U-lead software. Obviously, I do not expect people here to know anything about that software, but you might know of something in the iDVD software that will prevent the digital artifacts that I see when I use iDVD to make a slideshow. So far, the slideshows I've made are bordering on not watchable.

Really bad image quality on iPhone 6

I took a photo using my iPhone 6 of some kit that I needed to be able to identify later on. I was looking at the photo today and the fine detail is unreadable, it looks like some kind of pixelating filter has been applied to the image. Does the attached seem right? I'm viewing in Photoshop at 100%

Bad image quality when importing from word

When importing from MS Word 2003 to RH X5.0.2, embedded
images are converted to jpg whith an obviously quite moderate
compression qulity. This is particularly evident for screenshots.
Is there a way to improve the image quality?

Peter , these images were copied and pasted directly in to
the Word-document (using the Print Screen button) but I did find
out something. RoboHelp generates two image files of the types PNG
and JPG for each Word image (named, e.g., image102.png and
image103.jpg). Regretably, the lesser quality JPG is always
referenced in the topics instead of the much better PNG. Sometimes
the two images greately differ in size (pixel size), but most of
the time they are about the same size.
So the task might be to change the references in all topics
using a script and then manually checking the images for their
size.
An observation: Any GIF images in the Word file (i.e., real
*.gif files that were inserted over the Insert menue) remain GIF
files after the import, they are not converted and maintain a good
quality.

Bad image quality on stills

I apologize if this has already been addressed somewhere, but I have searched the forums quite a bit and found nothing about this.
I am creating a DVD for an advertising agency. One of the things they want on the disc is a section displaying print ads.
I have created a menu with thumbnails and when you select an ad it takes you to a menu with that ad blown up to full screen.
The problem I'm having is that the ads, even blown up to full screen, look really bad. There are jagged lines on all the edges of text and pictures and the copy just looks garbled and impossible to read.
The ads are very large, very high resolution pdf or psd files. They look great when I view them outside of DVDSP, so the problem is not with the source files.
On top of this, I am having the same problem with the agency's logo on the main menu. The psd file looks great in photoshop and is a very high resolution file, but in DVDSP it has jagged edges and loses color quality.
So my question is, what do I need to do to prepare my pdf or psd images so that I can bring them into DVDSP and retain the quality of the image? Also, I have been adding them to a menu as a drop zone...is that the best way to do it?
By the way, the problem is not with the encoding of the disc...all the menus and videos look great. It's just the still images that look bad.
Any help would be a lifesaver.
Thanks!

Bad image quality when connecting an external Dell 30" monitor. Why?

I recently bought the latest Mac Book Pro Retina 15. It's running the nVidia M750 2gb card I believe.
I'm trying to hook it up to my Dell 30" desktop monitor which runs my desktop computer perfectly well. I'm using a cheap Mini Displayport to Displayport cable which to do this. It's working except the image is slightly fuzzy, as though the resolution is just a couple pixels off native res. Could it be the cable being cheap? (I couldn't find proper ones when I bought this one) Or should I be connecting the screen via a different method? I obviously need the full 2560 x 1600 resolution.
Thanks,
Simon

Sure.
Here are the specs on a Moshi Mini DP to HDMI Adapter
You can see Supports full HD display at 1080p (1920 x 1080).
So no go there...
Altaz Mini DisplayPort to DisplayPort Adapter for Apple MacBook
So that would work for you. Review on link:
I recently bought one of these to try out with an Apple unibody (late 2008) MacBook Pro and a Dell 3008WFP 30" display.
Dell's web site advertised the 3008WFP as requiring Dual Link DVI to work at full resolution (which is certainly partly true, as normal DVI can't drive 2560x1600 displays). Given that DisplayPort is rated up to 2560x1600 I was hoping that this adapter would allow my MBP to drive the display at full resolution without requiring Apple's MiniDisplayPort to Dual Link DVI converter.
It works flawlessly for me.
So make sure you look for a cable that is rated above 1920 x 1200.
There are some examples here: http://daggle.com/macbook-run-2560-1440-monitor-2324

MBP Retina: Poor image quality from hdmi output

I just had to return a Macbook Pro 13" because of this problem. I was using a HP 2311 HDMI monitor. At first, the screen would only show the upper half of the dock. I was on the phone with Apple Care and they suggested I use underscan. It worked, in that it corrected the screen size problem, but the image quality, especially rating to text was ridiculously poor. There was no suggestion available as to how to fix this. Yet, in display it says that the display is optimized for the HP 2011.
I must say I was really surprised about this defect. I was even more surprised that the problem has been around so long without a resolution. There is no doubt that this shakes my confidence in Apple products. Thankfully, my iPad, iPod and Apple TV have always been reliable.

I've now tested with the following cables/adapters between my rMBP -> Dell U2410:
mDP -> VGA
mDP -> DVI
mDP -> HDMI
HDMI -> HDMI
HDMI -> DP
None of them work. Some people are reporting *minor* differences when switching from HDMI to DVI, but I think that's mainly psychological persuasion. In my experience nothing helps - fonts are still blurry, bad image quality. I've taken still photos with a Cannon DSLR to compare the pixels - no difference.
Someone also reported on other threads that lowering the Dell U2410's sharpness "solves" the problem, I find this to be untrue and a "fool's solution". Fonts do look sharper, but everything else looks horrible.
My understanding is that this is related to rMBP and/or Mountain Lion external display drivers. Hopefully this can be addressed with a software update. I really hope Apple is aware of this issue (many have filed bug reports).

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.

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

Image quality poor when using "fit in window" view

Hello,
i´m getting familiar with PS CS3 Demo and what buffles me is the poor quality of the downsized view of large images. I loaded a 8 MP JPEG image from a digital camera and it looks good in 100%, but when i choose to view the whole image to fit the window (33,33% in my case), the resulting "downsampled" image is very jaggy and pixelated. I use a freeware image viewer called Xnview that gives me a far superior view when viewing large images downsized - i can even choose to select a "HQ" mode so those images get resampled to look better. It it normal that PS does not offer such a thing (or did i not see it?) and delivers such poor visual quality or is there something wrong with my PC?
Thanks for your help.

Though 6.735, 12.5, 25 and 50% views usually are OK too. "Image quality" is great, though sometimes deceivingly so. I guess I don't understand sampling enough to tell you why 33% looks bad (rounding errors, I suppose). But 66% makes sense. You're trying to stuff 3 pixels into the space of 2.
Dave, what are the advantages to these nearest neighbor views instead of bicubic (or even bi-linear). Just speed?

Bad video quality of final product when viewing on computer in full screen

It looks like a picture does when you blow it up and it's a low quality image. Everything I'm reading says the problem would be with the video capture...but I have the same bad quality when I'm viewing the menu! Around all the text on the menu, it's fuzzy and same with my video on the menu. So are my video clips in the movie itself.
I have tried playing it on Windows Media Player, the apple DVD program, and WinDVD and I get the same problem when I view it on full screen.
I assume my family will mostly be playing it on a TV. Do you think it will play properly or worse on a TV? I don't actually have a DVD player myself to test it out. Any suggestions on why this could be happening?
Thanks!

when I started using iDVD, one of the hardest adjustments for me to make was video quality on TV screen vs on computer screen. (I am used to satellite to S-Video TV and HD screens on my computer.)
My camera it a miniDV, and playback via SVideo to an Svideo TV screen is awesome.
I was sorely disappointed when I played the same tape back on the computer. It was grainy/fuzzy, etc. Same with the DVD I made.
But when I played the DVD back on the TV, the image quality was the same as when I connected the camera to the TV - crisp, sharp, video and text.
I've since burned numerous DVDs, and the result is always the same - blah on the computer, sharp on the TV.
As someone else in this thread stated, the average TV is low-res compared to the computer screen.
If I recall the spec correctly, standard NTSC is 240 line, SVideo is up to 500 line. HD is 720 line and higher...ergo an NTSC source is roughly 1/2 the resolution of the typical CPU screen, or 1/3 the resolution of low end HD screens. So yes, NTSC output on your computer screen will always be fuzzy compared to your TV screen.
I think you will likely be very pleased with the DVD when you playback on your TV.

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
