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.

How can I change the image quality of a background image on a master slide?

I can change the image quality from low to high for other images in my Captivate project, but the background image I'm using on my master slide looks pixellated. I would like to change this image to high-quality but I don't see the option in my properties panel on my master slide.
Thanks for any help!

You cannot import AI images directly. However, when I use Illustrator drawings, I'll import them as smart object in Photoshop and then you can import the PS-layer.
The quality you set in Captivate is not for individual images, but for the slides that are published as bitmap. This means that it doesn't matter if the object is on a master slide or on a regular slide IMO

Photosmart 2575 sudden change in print quality

Hi
My father has had one of these printers for over a year now as has been using it successfully to print images from PC and direct from memory card. Until a few days ago when all images started to print much darker than before. This applies to new and existing images that previously printed without a problem.
The paper is the same, the ink cartridges are the same, and no settings had been changed on the printer.
In trying to rectify the problem he has so far:
Cleaned the Print heads
Changed the paper
Printed images from the PC and direct from memory card on the printer
Reset theprinter to Factory settings.
Increasing the Brightness option has very little effect.
All have made no difference.
Any help would be gratefully appreciated.
Bob

Hi Bob,
Would you be able to answer some of the questions below?
which cartridges are you using?
When you print a test page, how are the colours on there?
When you make a copy directly on the product, are the colours then also more dark then before? (not sure whether you can compare this but what is your 'gut feeling' on this one?)
What is the ink level? (below you will find steps how to check this)
The Ink Status window is part of the printer software and appears each time the printer prints a file. The window automatically displays the approximate ink level of each print cartridge. If you turned off the Ink Status window and want to check the ink cartridge levels in between print jobs or turn the Ink Status window back on, follow these steps:
Open the Printer Toolbox . There are two ways to do this:
Select Start and the HP Solution Center select the Settings menu, then the Print Settings submenu, and finally thePrinter Toolbox .
Or in your printing application, select File , Print , and click Properties . Click the Services tab, then the Service This Device icon.
The Printer Toolbox opens. Click the Estimated Ink Levels tab. A cartridge may be running out of ink even if the graphic shows ink remaining (see the note at the start of this section). Lines or streaks always appear in printouts when the cartridges begin to run out of ink. Replace print cartridges that are out of ink or low on ink.
To turn the Ink Status window back on, select the Configuration tab and check the Display Ink Status Window option. The Ink Status window will appear each time the printer prints a file.

IPhoto is changing resolution and image quality

I am currently and for the first time using iPhoto 6 to produce a book - a feature within the application. I have edited my images in Photoshop, some have not needed to be so they have simply been saved as either high-res JPGS or TIFFS. On importing them into iPhoto selected images are downsizing and stating that they are not big enough to print - this I know is not true as they are adequatley large enough for printing to A0 minimum at 300 dpi. There are also a select few that are changing in image quality - the colours are looking either bleached out or over-exposed and they have lost their original quality. When opening the exact files in Photoshop they are correctly exposed, perfect colours, sizes etc. If I am to try and 'retouch' them within iPhoto I can resume some of their quality but it seems through the transition into importing inot the application they are being corrupted.
Can anyone assist me as its driving me mad!!!
Thanks

What is the color space of the photos in photoshop?
In iPhoto Preferences, Advanced, do you have it set to add ColorSync Profile?
BTW, the 72 ppi (pixels per inch) is irrelevant. iPhoto defaults to reporting 72 ppi because that is a typical screen resolution. What's important is the total pixel dimensions of the image, and whether that size gives you an adequate dpi (dots per inch) when printed at the designated print size. So, while the image looks great on-screen in photoshop, that doesn't mean that it will be adequate for printing in a book. But you are right - you shouldn't see a significant shift in color when importing into iPhoto.
Regards.

Safari 7 in Mavericks-Web image quality problems?

Suddenly, my browser image quality has gone south. Web page images load, but they are very poor quality, and blocky. I have made no changes to settings, nor updates. Any ideas on how to fix this?

Workaround: the video had been embedded as
<object type="video/quicktime" data="mov.mp4"
height=470 width=550>
</object>
I changed that -- using the HTML 5 video tag instead --
<video height=470 width=550 autoplay>
<source src="mov.mp4" type="video/mp4">
</video>
This works. Perhaps the prior syntax is deprecated?

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.

Image quality in ePub exports from Pages

Something changed in ePub exports of images recently, or in iBooks' rendering of them. Now they are fuzzy when double-tapped and enlarged. Originally (at beginning of iBooks) they popped up looking quite crisp.
Oddly, I can still get crisp images with double-tap if I export an ePub file from Scrivener, and import it into iBooks—using the same images I'm used in Pages.
Does this make any sense? Have others noticed this change in image quality?

Just for the sake of clearness - InDesign 5.0 = InDesign CS3
InDesign CS5 = InDesign 7.0.x
I suppose you are talking about InDesign CS5 and not something older.

Aperture image quality

I am trying to export some pictures from Aperture. When I export the picture I notice the image file size is smaller when I export it. The image goes from 2.9 mb to 2.5 mb. The image quality is set to 10. When I change the image quality setting to 12 it goes to 5mb.
What image quality size should I pick? I want the best possible to print a 8x10 picture.

What you are getting now most likely is equivalent to your original source, say a camera, minus some info imported originally, since you are seeing a file size that also is clearly a JPEG?
This is probably adequate for giving to a printer. If you were printing from Aperture yourself, that is what you would be using since the original source is roughly that size.
In the Export dialogue, click on the arrows beside the selection of Original Size, and choose Edit. What options are selected, particularly with regard to metadata?

Image quality lost through editing with Photoshop?

I find a number of professionals using Lightroom as their primary photo editor.
I did a search on Lightroom vs Photoshop. I found the following listed as the first reason for choosing Lightroom: 1. Nondestructive Editing. Nothing is actually changed (by Lightroom) in an image until it is exported. This means you can make an adjustment, change it again and again, but no quality is lost as it would be with Photoshp. This is reported in Outdoor Photographer.
My impression is there is no lost of image quality in Photoshop if you are working on a layer copy of the Background. Photoshop tries to prevent degradation of the original image by requiring it be copied or otherwise freed before the background can be changed.
Image quality can be lost in downstream layers through processes such as changing image size.
Is my statement correct about loss of image quality and the 'analyst' from Outdoor Photographer misstating things?

Hi Vince.
I am just learning my way around Photoshp. I have spent 18 months learning how to start and to stop it.
Good point. But if we peg the learning curve of Ps at 10, Lr comes in around 2 or 3. Like learning to drive a car as opposed to learning to fly a jet.
Smart Objects would make PS more re-editable.
True, but still no match for Lr or Ps RAW.
I have never before seens a comment that extensive work on an image in PS would deteriorate the quality of the image.
Extensive work will do what the user asks it to do. In the first 18 months I had Ps, I asked it to do lots of things that I now realize deteriorated my images. Forever.
Regarding LR, I have created for me a workflow that requires PS.
So did everyone before Lr came out. And yet, Ps users by the thousands, if not millions, have adopted Lr. Many if not most with a greater time investment in Ps than 18 months. I dropped my Ps centric flo the moment I realized what Lr could do. I had been using Ps pretty heavily for about 5 years by that time.
I feel LR works best for experienced photographers who are shoooting a lot of pictures.
While it's true that experienced photographers might realize more benifit, maybe not. It works great for everyone.
That person has good images, images that need little editing, to start the output process.
This is not true in the sense that the majority of Lr users are mediocre photographers at best. For the simple fact that most photographers (even "pros") are mediocre at best. And Lr was conceived with these folks in mind. It has the true "pro" stuff, but in an amateur friendly environment. Judging by the images and questions posted on photo and Lr forums, there are many, many, low level photographers using it.
I am an inexperienced photographer shooting just a few pictures. So I put a lot of effort into getting a good print from my mediocre shots.
You obviously care about your images. Care more when you are shooting them. This is boiler plate advice. Time spent mastering your camera will pay off better dividends than learning to fix bad photos. This was true before the digital age, and it's just as true now. Ultimately, no matter how hard you massage it in Ps, Lr, or any other app, the quality of your final image will be a function of the quality of the original pixels you captured with you camera.
So far as masks and all the rest, Lr has an Local Area Adjustment Brush which does just that. You paint the mask, complete with any number or combination of adjustments, with a brush. The mask and the adjustments to it can be easily changed later. A good spot removal tool. A great red eye tool.
File size isn't a huge factor these days, but it still counts. Instead of layers and the pixel data for each of them as in Ps, Lr has the pixel data once, and a sidecar file with the adjustments settings in a much smaller file. Not a big deal for storage, but when rendering, maybe a bigger deal. Lr also pre-renders previews at various sizes (you can program this, plus how long it keeps them). I could go on and on (and I have).
Bottom line, it's a great tool for anyone who takes photos. For the price, it's a no brainer for $150. If you have the $150. Not true for many of us these days.
Anyway, Vince, I hope you don't think I'm picking on you. I answered you in detail because you made such good points. And the answers might be of general interest.
Peace,
Lee

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!

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?
I'm running Mac OS X 10.5.7 on a Macbook Pro from late 2008 (Unibody)
Bendix

Here you go with a screenshot:
http://www20.zippyshare.com/v/38662055/file.html
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.

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)
