Low Quality Pictures

Hi,
I have spent several hours working on an iPhoto book. Several of my pictures are pictures I scanned into iPhoto from a traditional photo. Anytime I use these pictures, a yellow trianlge with an exclamation mark comes up. It says the quality of these pictures is low. Will it look okay if i print the book anyway?
Removing all the pictures isn't really an option since they make up more than 50% of my book.
Thanks for any and all responses!!!!

Looking OK is a personal opinion - no one other that you can make that judgement
What we can say is that if you have the low quality warning the photo quality will not be as good as if you had a higher resolution photo that did not get the warning
In cases where I wanted a photo and had no ability to get a higher resolution photo I have used them
Your best bet would be scan the photos again using a high enough resolution to have at least 200 DPI for the final print (the warning comes on at either 150 dpi or 180 dpi - there is some confusion about that)

Rear Camera taking grainy low-quality pictures -- help?!

I just bought an Iphone 4 3 days ago. I've started using the camera but all of the pictures seem to come out really low quality, grainy and blurry and when I upload them to flickr they have 765 x 1024 resolution. I've seen lots of pictures other people have taken with iphone 4s and they look really sharp and crisp and have much higher resolutions (2592 x 1936). Is there a way to adjust settings? Do I have a defective camera? Here is a link to the pictures I have taken with the rear camera: http://www.flickr.com/photos/scmarvelli/

Have you taken the protective film off the back?
There is no adjustment regarding the size of the photo. How are you getting them off the phone? If you drag them off using Camera/Scanner Wizard they will be full res

Iphoto low quality pictures

I'm making a photobook and it says a few of my pictures may print at a lower quality. I'm just wondering what lower quality means: its a little pixelated or completely blurry. Any suggestions?

You can create a PDF of the book according to this Apple Document and check it to see if the image will meed your expectations: iPhoto, Aperture: Previewing an order in iPhoto or Aperture
Not actually a good test as a 72 DPI image looks perfect on a display screen but prints terrible - best to go by actual printed DPI rather than screen display since a screen is a totally different anminal and both colors and resolution work completely differently for screens
Apple's suggested minimum pixel dimensions for disserent size prints are in the link I provided
doing the calulation I recommended is the best idea
the basic rule is that photo smust be 150 DPI or more for good prints - so you divide the pixels in each dimension by the inches being printed in that difection - if the answer is 149 then things should be fine - it is is 25 then things will be very bad

I want to run Photoshop and Light room on my mac, but I'm worried that osx only running eight bits of color will lead to lower quality picture results. Should I stick with Windows?

The headline sums it up. Will running the programs in Windows result in better pictures? Do professionals do touch ups on Mac? Thanks for your responses! I'm new to this.

"Deep colour" - meaning a 10bit colour driven display - can only be achieved in hardware with a screen and a graphics card that support both. The average Windows system does not support this - few do. Only Windows workstation level graphics cards from AMD and Nvidia support this option. These are generally more expensive than consumer cards of the same caliber.
Many screens with so-called 10bit support often fake the extra colours by introducing dithering - true 10bit displays are only manufactured by companies such as Eizo - and they are expensive: prices range to around almost $2000 for a 24" 10-bit screen from Eizo. You also need a special HDMI cable, I believe.
Also, the software must support a 10bit workflow. These are far and between. I believe even Lightroom still does not support this - Photoshop does from version CS5 and up.
If you have a hard time understanding all this: no worries. The reason why you are confused and worried is because you lack the know-how, and, subsequently, reading all that "10bit colour is unsupported on Macs" made you anxious.
In reality, while Windows does support this (and Macs do not), almost no-one uses it currently (beyond high-end film/FX work, cad/cam, and a couple of high end Photographers). Any generic consumer and even most workstation level Windows machines will not support it unless all the hardware and software is properly set up. And it is very costly. Colour management becomes even more intricate with 10bit displays.
In a nutshell: much ado about nothing. A Mac is great for design work, as are well equipped Windows machines. By far the majority of professionals in Photography, Graphic design, Video and Effects editing, and so on, currently work without 10bit hardware, and produce outstanding work.
Unless you are spending at least around $2000 on screen hardware, and limit yourself to a very small group of applications that also cost an arm and a leg, you are not going to be able to use 10bit on Windows either.
You can forget what you have read - it is of no consequence to you. (or if you are interested, learn the technical backgrounds.) Perhaps in 10~20 years the situation will have changed.

Showing lower quality photos in slideshows

I'm trying to create a slideshow that has a mix of high-quality pictures that look good full-screen and others where the quality is much less and shouldn't be viewed at full screen. I cannot figure out a way to show the low-quality pictures in a slideshow at less than full screen. Is there a way to restrict their size to the optimal viewing size rather than spreading them to full screen where they become grainy and blurry?

Welcome to the Apple Discussions. There is no way to create a slideshow with a smaller image on the screen than the options in the Setting pane.
There's a 3rd party slideshow application, PhotoPresenter, that has some wonderful themes that do not require the photo to fill the screen that might work for you. You can try it in demo mode before deciding to purchase. This is one of their fancier themes.
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.

Ken Burn pictures look really low quality

Putting high quality pictures into movie and when I ad ken Burns affect they look very low quality as the effect is in process. Do I need to add a lower quality pic? Any suggestions would be very much appreciated.
Keith

they look very low quality as the effect is in process.
usual advice:
never judge pic quality within iM (lowered preview quality) nor on a computer either.. (iM is for TV delivery.. iM≤6 ... )

After import from Iphoto some pictures are of very low quality. The original file in Iphoto is very good.

Final cut Express
I imported several pictures by using Iphoto. Some of them, not all, are of very low quality even if the original file is of a very good quality.

It sounds as though you may have imported the thumbnails but I can't imagine how.
It all depends on what you mean by very low quality.
Your iPhoto pictures will be around 4,000x3,000 pixels but when they are imported into a standard def timeline they will be around 720x540 which is a tremendous reduction.
They should still look OK but not as good as the brilliant hi-res originals.

Why is it that when I connect my iPhone 5S to my Windows Vista computer, the photos made with my iPhone are all of very low quality and most of them are turned upside down?

Why is it that when I connect my iPhone 5S to my Windows Vista computer, the photos made with my iPhone are all of very low quality and most of them are turned upside down?
On another note, the iPhone tells me that it's ''busy'' when opening a photo on the computer.
(I tried restarting my PC, connecting via another USB port, importing using PhotoStream, etc...)

Are you using the front or rear camera? When you say they are low quality, are you referring to file/pixel size, or how the picture looks? As far as upside down, how are you holding the phone? Older versions of Windows have issues reading the Metadata from the pictures and will not display the same.

Photoshop Elements 11 Organizer: Full screen view of lower quality than with PSE 10 and before?!

Upgrading from PSE 10 to 11, I noticed that when I watch my images with the organizer in PSE 11 in full screen view mode (F11), while the images load faster, they are shown in a lower quality than in PSE 10 or any other version of PSE that I owned before. In PSE 11, after the initial viewing in full screen (in the "fit screen" mode), when I click with the mouse on an image to display the "100%" view, there is a delay and the program says "Loading...", after which the 100% view in the full screen mode appears. When I then click another time with the mouse on the image to get back to "fit screen" mode, I get an image of better quality than during the initial view!
So it seems like the program first gives a faster, but lower quality view of the image in full screen mode, and only after the user requests a 100% view, it actually loads the image with full detail, which is then preserved when going back to the "fit screen" view. This is a serious issue for me, because I also use PSE organizer to present my pictures to other people, and I don't want to show them some lower quality versions of my images, but the full quality ones, without having to first choose "100% view" and then go back to "fit screen".
How can I make the PSE 11 organizer give me a full-quality full screen image right away, as this used to be the case in PSE10 and before?
(I have both versions, PSE 11 and PSE 10, now on the same computer and tested this to confirm that the PSE 11 initial full screen view is of lower quality than the PSE 10 one. Also in PSE 10, there is practically no delay for displaying the "100%" view afterwards, indicating that the image was loaded with full detail right away.)

- Update:
* Adobe's senior support level has replied to me about this issue as follows:
"Thank you for contacting Adobe.
When you press the F11 button, Organizer 11 uses the Bicubic
interpolation mainly because it is less processor intensive compared to
Bicubic Sharper, and it helps to create the preview on the fly, rather
than based on the thumbnail cache.
When you zoom out from the 100% view, Elements Organizer uses Bicubic
Sharper. This is because Bicubic Sharper is used for image reduction, so
if the 100% view is larger than the available screen space, it will need
to shrink. The Bicubic Sharper images may look more crisp however, Like
any sharpening algorithm, Bicubic Sharper introduces halos and
edge-enhancement artifacts. Those halos are typically slight, but any
further sharpening (which you'll need when preparing an image for print,
for example) will exaggerate them.This is expected behavior. The
Organizer isn't great for determining exact quality, I recommend you to
use Elements Editor for this purpose.
Thank you,
Bobby Johnson,
Adobe Technical Support."
* My reply on this to Adobe is:
"Hello Bobby,
thank you for your reply. Now at least we are talking about the same thing.
Why I am wondering about the choice to use the "Bicubic" algorithm when pressing F11 in PSE 11 is that all previous versions of PSE that I owned (which spans from PSE 6 to PSE 10) did use the "Bicubic Sharper" algorithm right away when pressing F11. So apparently Adobe didn't worry about processor intensity of this algorithm then, and computers are getting all the time more powerful.
It is true that in some situations, the "Bicubic Sharper" algorithm may introduce halos and edge-enhancement artifacts, as you write. On the other hand, especially on smaller resolution screens, the results of the "Bicubic Sharper" algorithm may look more crisp and lively, while the ones of the "Bicubic" algorithm may look more flat and lack fine detail. This is not only my personal opinion, but as I have brought up this topic in several forums, I can see that I am not alone here.
So assuming that the question about preferring "Bicubic Sharper" or "Bicubic" as a default algorithm when pressing F11 is partly a matter of taste, and partly a matter of the hardware the user has available, why can Abobe not give the user an option to choose which one he/she would prefer? For instance, F11 gives full screen view with "Bicubic" applied, and CTRL+F11 with "Bicubic sharper"? Or make this an option in the preferences?
As I am using the PSE organizer also to present pictures to other people (and I know many people who use it that way too), I would like to show them my pictures as sharp and detail-rich as possible. Therefore, I would highly appreciate an option as described above to be implemented in the PSE 11 organizer via an update. It should be fairly easy from a programming point of view, since both algorithms are already contained in the program anyway."
* If you support this suggestion of mine as stated above, please also contact Adobe accordingly! The more support requests they get for this, the more likely it is that they will implement this update! You may mention my case number 0184046323 for reference.

Just upgraded, low quality warning on all photos?

Hi All,
Hoping someone can assist me here. Just upgraded to iPhoto 6 and was experimenting with the greeting card function. Apparently, all of my photos (unretouched & uncropped) which are 1704 x 2272 at 180 dpi are too low quality to print reliably. I'm trying to print the images at 5x7 or smaller, and as far as I understand 1704 x 2272 should be adequate, but I get the low quality warning on every picture in my library. I use a Canon Digital Elph S400 at maximum resolution/quality, am I going to need a higher megapixel camera to produce images of sufficient quality for the online printing services? Any advice appreciated.
Thanks in advance,
Jennifer

Jennifer:
Welcome to the Apple Discussions. Sound like somethings broken in iPhoto. First run Disk Utility and repair disk permissions. Then, if needed, go to your User/Library/Caches folder and delete the iPhoto folder there.
Next, log into another account on your Mac and see if you can create a card and not get the warnings. If so then your primary account has some incompatibility with iPhoto. If you get the warning then it's probably iPhoto and you'll need to reinstall iPhoto. If you do have to reinstall iPhoto you'll have to delete the current application and all files with "iPhoto" in the file name that reside in the HD/Library/Receipts folder. Be sure to repair disk permissions after the installation and updates.
Do you Twango?

Low quality images in web gallery from Output Module

So when I create a web gallery slideshow using the output module I get SUPER-low quality images, like big jagged, pixellated lines in place of any diagonal line in the pictures. However, only photos in the portrait orientation are affected by this problem. Landscape-oriented photos look perfectly normal, just smaller.
My first thought was that maybe the images were low quality in the web gallery preview but wouldn't be in the actual saved file, but alas I saved the index.html file and when I preview it in my web browser I get the same result with the portrait-oriented photos.
Any idea how to fix this? Other than only using landscape photos in my gallery of course!
Thanks!

The same problem here. I've noticed it just yesterday, but my Safari rendering is affected the same way.
I don't think it has anything to do with the recent updates. I reinstalled my MacOS X Leopard day ago and all the images (jpg, gif) have been somehow in lower quality ever since that moment. Even before I installed all new updates today.
The strangest think is, that it wasn't like this before the reinstallation. I used the same media, and I have, indeed, the same machine.
I'm hopeless. Have you already found some solution? Or anybody? Would be great...

Bad quality pictures in dim light

When I'm in dim light situations, (Bar) my pictures are grainy and really dark. When I used several of my friends iPhones to take additional pics, I noticed 1) the image on the screen before taking the picture is brighter. 2) the picture is is better quaility, more vibrant. My comparison was against 2 other iPhone 4S'. Also, when using my flash, the pics have a blue tint. I always assumed that this is because of the use of an LED as the flash. Compared to both my friends iPhones, theirs is more normal looking.
Should I just take it into the Apple Store and let them deal with this?

You answered your own question. It's the low light.
What is the solution to this issue?
Are you using the flash?
You might also want to try out an app called King Camera. It allows a bit of control over exposure that might help.

Upgraded to CS5.5. Images in Indesign are displayed in lower quality after being saved in PS

Hello,
i upgraded to the Creative Suite 5.5 today and detected a strange behaviour. I work on a document which has been generated on another system with an older version of the Creative Suite. Everything is
fine until i open and save one of the images which are used in an Indesign-Layout in Photoshop. After doing this the saved image is displayed with lower quality than before while all other pictures
remain at the same preview quality level. Of course i can change to »Überdruckenvorschau – maybe overprint preview« (Sorry - i do not know how this is named in the english version) or change to the high quality view but
this is a little bit too much for working.
Do you have any ideas?
thank you so much,
tm

I suspect the old High Quality preview was retained (like the text layout will be retained on a converted file until you touch the story in some way, at which point it will be recomposed using the new text engine) and when you replaced the image a new prview as drawn using the current view settings.
Enable High Quality Display if that's the view you want.

The Time Machine backup of my photos is a lower quality than the originals?

I recently had some problems with my mac and ended up deleting my iPhoto library. Fortunately, I had a Time Machine backup that was only missing a few months. When I recovered the iPhoto Library from my Time Machine and loaded it into iPhoto, I realized that the pictures are in a lower quality (almost like thumbnails of the originals). Is there something I may have done wrong, or is there anything I can do to get my original photos back?
Any help is greatly appreciated...

Try right clicking on the iPhoto Library and "show package contents" it's really a folder and inside should be a folder called Originals.
Copy this folder out onto the desktop and then delete the iPhoto Library, then restart iPhoto and reimport the Originals.
