IPhoto book low quality warning?

I've created an iPhoto book. I'm ready to buy it but I get a warning that some of the photos are too low quality for the type of book I've chosen. Yet all photos were imported at 300dpi and there's no warning on any one photo that the quality is low. How do I determine which photo(s) are the low quality ones?
digital photos do not have a "DPI" until you select a size to print them - See The Myth of DPI for additional information.
someplace in the book you have places a photo which will not be at least 180 dpi when printed at the size frame you placed it in - if you have carefully gone through the book and do not see and low res warnings it is possible that there is a full page photo behind another full page photo - this can make it difficult to find
Before ordering your book preview it using this method - http://support.apple.com/kb/HT1040 - and save the resulting PDF for reference - the delivered book will match it.

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

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.

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.

Low quality warning

I have a calendar made in iphoto 9. When trying to save to PDF or previewing a low quality warning, which I can only partially read, appears and the rest of page is blank. I have checked the photos on the page and replaced them. I don't understand why this is happening. I have saved this same calendar before as a PDF with no problems. I recently made a few changes, but not on the page that the warning is appearing on. There is a red alert icon on one of the calendar pages and oddly it has moved. It was on one month and now it's on another month. I don't want to redo the entire calendar. Please help. Thanks.

Have you previewed this way -

IPhoto Book Paper Quality

I have ordered books before from apple and was happy with the results. I am considering ordering a large amount of books from another printing company. I was asked what kind of paper weight/gsm I would like. I have no idea, but was wonder if anyone knew what paper weight/gsm apple used in there books as at least I would have an idea from the books I have already printed and in my hands for reference.
Thanks John T

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)

Importing iPhoto books back from pdf files

I saved my book on a cd in pdf. I want to put it back into iphoto to print more books - iphoto said it couldn't read the format. How do I do this?

sjrb:
You can't back engineer a book from the pdf file. You might however do a Print to PDF and select the Send PDF to iPhoto option. That will give you jpg files for each page of the pdf. You might be able to create a book with all pages in a 1 photo per page layout and use those jpgs of each page. It won't be as good as the original but may be acceptable.
The pdf conversion process produces jpgs that are 2200 x 1700 x 200 dpi which do not give a low quality warning when put a 1 photo/page layout. You'll have trouble with the cover and will have to find the photo for it and redo it with a photo. Worth a try.
If I may offer a suggestion. In the future create a separate library for the book, add the picture you want in the book to an album in the original library. Then use iPhoto Library Manager to transfer that album to the book library and any more photos as you go along. When you're done you can burn that book library folder to a CD using the Finder to archive that book. If you want to order another book at a later day, copy that library folder back to the desktop, open it iPhoto and order another exact copy. Delete the folder when done.

I'm trying to do a book using iphoto 11 (9.4.2), but i don't get a low resolution warning. Why? and how can i get the warning., i'm trying to do a book using iphoto 11 (9.4.2), but i don't get a low resolution warning. Why? and how can i get the warning.

I'm trying to do a book using Iphoto, but it no longer gives a low resolution warning like it used to in the older versions.
I don't know why it doesn't anymore, (or maybe I have to add it on somehow??) but it makes it difficult to know how much I can
zoom in on a picture and still have it be good printable resolution.
Does anyone know how to resolve this or add the warning to the latest version of iphoto?
Thanks

With iPhoto 9 the low resolution for photos warning has been dropped. The only warning one will get now is for text that has overflowed the text box:
As Larry suggested send a feature request to Apple via http://www.apple.com/feedback/iphoto.html to get it back. That's a big omission in my opinion.
You can determine what your minimum resolution is for your images (if all taken from the same camera) by dividing the pixel dimensions by the size of the larges frame in the book which would be 8.5 x 11. If it's at or above 150 dpi you'll be above Apple's previous resolution warning limit.

How does iPhoto play a part in this? You're in the iPhoto forum. Shouldn't you be asking your question in the iPhone forum? I'll ask the powers to be to move you question to the iPhone forum.

HT1044 Low resolution warning in iPhoto 09 but on screen looks great

Hi:
I'm working with Snow Leopard and iPhoto 09. I'm building a book and have added photos. Some of the photos show a low resolution warning.
I'd like to keep them at the size shown in the book. I've increased the zoom on the pages and the photos look crisp and clean. Should I be concerned
about the low res icon then?
OR where do I find dpi info and how do I increase it?
Thanks everyone!
Terri
Here's a sample of the pic:
file://localhost/Users/terrimcreynolds/Pictures/iPhoto%20Library/Originals/2008/ R.%20Back%20to%20Venice/R_623.bmp

1 - yes you should be concerned - that is why there is a warning
2 - screens display images at 72 DPI - printing requires at least 150 DPI and 300 API is better
3 - you can not "increase DPI" since it is a mathmatical caculation - Dots Per Inch - Dots (pixels) divided by inches
4 - the solution is to use another photo or to reduce the "zoom" so that the photo does not have a warning

IPhoto Book Quality

I am interested in hearing about other peoples experiances with the print quality of thier iPhoto 6 books.
I have ordered two iPhoto books, the first about a year and half ago with iPhoto v5 came out spectacularly. The most recent I just received today ordered via iPhot v6. I am not to happy with. It has the following problems...
1. Washed out colors. Several of the photos have distinctly muddled colors. This washed out effect is not consistant and varies from photo to photo.
2. Blurry photos. The printing process has severely blurred some photos as if the print heads of the printer where misaligned.
3. Banding. Several of the photos indicate print banding such that occurs on low end inkjets.
4. Print artifacts. Several pages contain marks and blemishes in the white borders and margins.
I have emailed support asking to retun the book but beyond that does anyone have ideas of things I could do to get a better quality print out? Thanks.

Welcome to the Apple Discussions. I've had very good luck with book but others have experienced what you have to some extent or another. It's probable that your book is a on time error and you should contact Apple and ask for a refund - http://www.apple.com/support/iphoto/customerservice/orderbooks/. Apple has been very good at correcting such problems.
Regarding quality of the books and materials the following is what I received back from Apple regarding an email asking about material and print quality:
I contacted Apple and asked for information that I could pass on. Here's the reply I received from Apple:
"Thank you for contacting the Apple Print Products Customer Service.
I understand that you would like to know the printing process that is used and the color mode the files should be in, so you can better advise users in the iPhoto forum.
iPhoto version 4 or later, allows you to import and print files through the Apple Print Product service as RGB, grayscale, or CMYK color space. JPEG files with RGB color space are recommended for best results.
While iPhoto 2 can import files of various formats, including RGB color, grayscale, and CMYK, this version requires JPEG files with RGB color space when printing photos and books.
For more information regarding iPhoto 2, please visit the following article:
iPhoto: Color, Black and White Prints Appear Garbled or Distorted
For more information regarding iPhoto 5, please visit the following article:
http://docs.info.apple.com/article.html?artnum=165501
Here are some of the technical specifications for the books, cards, and calendars. I hope this gives you an idea about their quality and form.
BOOKS
All iPhoto books are printed using acid-free paper for long-lasting image quality. The photos are printed at a high resolution (300DPI if you use iPhoto 6). There is no external modification--such as sharpening or contrast adjustment--of the photos; what you see in the application is what is printed in the book.
Hardcovers Books
The cover is hard-bound and covered in linen. You select the linen color during the book-ordering process. The hardcover books have a solid, stiff binding that is glued and crimped. The internal pages, measuring 8.5 x 11 inches, are printed on McCoy 100# Text Gloss paper stock.
Softcover Books
The softcover books come in three sizes:
- Large 8.5 x 11 inches
- Medium 6 x 8 inches
- Small 2.6 x 3.5 inches
All of the softcover books have internal pages that are printed on McCoy 100# Text Gloss paper stock. The large softcover book has a white cover (Kromekoteplus Folding Cover, 16 point) with a cutout on the front that reveals the cover-page photo in the book. The covers for the medium and small softcover books have the cover image and title printed directly on the cover. All of the softcover books have a glued binding and feature a thick cover of McCoy 100# Cover Gloss paper stock.
CARDS
All cards are printed on McCoy 120# Silk Cover paper stock. The postcards measure 4 x 6 inches, and the greeting cards measure 5 x 7inches.
CALENDARS
All calendars measure 8 x 10 inches and are printed on McCoy 100# Silk Cover paper stock.
To ensure the best print quality, we have chosen to use Kodak NexPress technology. The press uses a dry toner, which is fused to the surface of the paper. Please see NexPress' site for more information:
KODAK NEXPRESS 2500 Digital Production Color Press
I hope you find this information helpful in answering questions on the iPhoto forum."

Red Triangle warning iPhoto book

Help, I have looked at the discussions but nothing seems to help.
I have save the book as pdf to see how it looks but nothing shows wrong on that either.
I am using latest iPhoto 11 to make a photo album/book to print for relatives. The format
looks good for both text and photos

The low resolution warning means, that the pixel size of the photos is too small for the size of the photo box on the page. As a test, move one of the photos to a smaller photo box, for example, from a page with one photo to a page with four photos. Does the triangle vanish? If yes, then scan the potos again with a larger pixel size or use smaller photo boxes, see:

Print quality / resolution for iPhoto books

Hi -
I am getting ready to upload my first iPhoto book for printing, and a colleague told me to beware of a potential issue. After searching these forums, and searching Google, I found that people in the past (perhaps prior to iPhoto '08?) have had print quality problems when printing 8.5 x 11 books vs. 6x10 books.
Basically, we are creating an 8.5 x 11 book and will have several books printed by Apple. At some point in the future, we will make similar books at the 6x10 size. Will the photos that are included in the books print at similar quality?
Thanks -

I have ordered books in the past that were made up of photos 1600 x 1200 pixels in dimension and they came out fine. HOWEVER, I had no pages with a photo filling the entire page as Larry warned about.

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

IPhoto low quality message

Building a book and when holding mouse over an image, I get the "This photo may print at too low a quality" message but the yield icon is not appearing. Can I ignore the warning?
Message was edited by: Warren Beach

Yes you can -- at your own risk - apple will not stand behind the print quality of a photo that has the low resolution warning - it comes on if the photo will be below 180 dpi
So depending on the exact situation you can ignore the warning, select a different photo, reduce the cropping or select a smaller photo frame.
