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

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 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?

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.

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.

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.

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.

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 ... )

HT1044 Will an iphoto order print with low quality warnings on it?

Will an iphoto order print with low quality warnings on it?

I think so but if you're orderikng large photos they may be a bit fuzzy depending on the pixel dimensions. What are the pixel dimensions of the image giving the warning and what size print are you ordering?
Here are the results of a print test that I ran. The pixel dimensions are the minimum that won't give a warning for the sizes shown:

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.

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.

Aperture 3: low quality preview images

I don’t know if it's just a problem with my (new) Aperture Trial library or if it's a Aperture 3 bug:
The preview images Aperture 3 (trial) creates from raw files (in my case NEFs) are different from the JPEGs exported using the same JPEG settings.
I get the impression that the preview images don’t use all the adjustments applied to the raw files. They don’t have the moire reduction applied. The preview images of high ISO images have color noise, the exported images don’t have that color noise (the moire and noise settings of raw fine tuning are applied to the exported files but not to the image previews).
As the preview images are used for the Finder media browser, iLife, iPhone/iPod touch picture sync and other things the lower quality is not acceptable for me.
The preview images of Aperture 2 are identical to the exported JPEGs from Aperture 2 (using the same settings).
I use Aperture 3 Trial with a new trial library and a few hundred raw images just to test Aperture 3.
I already erased all preview images and rebuild the previews. I deselected using the embedded JPEGs from the raw files and I let Aperture rebuild the miniatures.

It seems that Ap2 syncs the previews to the iPhone... you have to clear the previous cached previews before it will load higher quality previews... anyhow, here is what I did... and photos look better on my iphone (not feeling motivated enough to verify if it is the same quality as iphoto sync)...
1.) change Ap2 prefs for "limit preview size" to "don't limit"...
2.) select all the photos in the album(s) you are want to sync, right click (ctrl click), and select delete previews...
3.) sync your iphone again...
if that doesn't work directly, you might need to uncheck sync photos to delete all photos on the iphone, but the ultimate goal is to ensure refresh with the higher quality previews...
Hope that makes sense or gets folks in the right direction... Apple really needs to put a check box in future version of itunes to sync full quality or something...

Why are my iphoto 11 slideshow pictures distorted in idvd?

I want to create a dvd of my slideshow I created in iphoto 11. I shared it with idvd and the pictures were distorted. How can I fix this problem? Thanks for any help.

Hi
A. I don't know - I don't do it like that. Lack of KnowHow.
B. I do it by using either a video-editor or a dedicated program
• iMovie HD6 or FinalCut any version
• FotoMagico™
I do not use - iMovie'08 or 09 or 11 - as they discard every second line in export to iDVD (What evere way one take)
To get as high quality possibly - read
DVD quality
1. iDVD 08, 09 & 11 has three levels of qualities. (version 7.0.1, 7,0.4 & 7.1.1)
iDVD 6 has the two last ones
• Professional Quality (movies + menus up to 120 min.) - BEST (if movie + menu is > 60 minutes)
• Best Performances (movies + menus less than 60 min.) - High quality on final DVD
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6) (movies + menus up to 120 min.) - slightly lower quality than above
About double on DL DVDs.
2. Video from
• FCE/P - Export out as full quality QuickTime.mov (not self-containing, no conversion)
• iMovie x-6 - Don't use ”Share/Export to iDVD” = destructive even to movie project and especially so
when the movie includes photos. Instead just drop or import the iMovie movie project icon (with a Star on it) into iDVD theme window.
• iMovie’08 not meant to go to iDVD. Go via Media Browser or rather use iMovie HD 6 from start.
3. I use Roxio Toast™ to make an as slow burn as possibly e.g. x1 (in iDVD’08 or 09 this can also be set)
This can also be done with Apple’s Disk Utilities application.
4. There has to be about or more than 25Gb free space on internal (start-up) hard disk. iDVD can't
use an external one as scratch disk (if it is not start-up disc).
5. I use Verbatim ( also recommended by many - Taiyo Yuden DVDs - I can’t get hold of it to test )
6. I use DVD-R (no +R or +/-RW)
7. Keep NTSC to NTSC - or - PAL to PAL when going from iMovie to iDVD
8. Don’t burn more than three DVD at a time - but let the laser cool off for a while before next batch.
iDVD quality also depends on.
• DVD is a standard in it self. It is Standard Definition Quality = Same as on old CRT-TV sets and can not
deliver anything better that this.
HD-DVD was a short-lived standard and it was only a few Toshiba DVD-players that could playback.
These DVDs could be made in DVD-Studio Pro. But they don’t playback on any other standard DVD-Player.
Blu-Ray / BD can be coded onto DVDs but limited in time to - about 20-30 minutes and then need
_ Roxio Toast™ 10 Pro incl. BD-component
_ BD disks and burner if full length movies are to be stored
_ BD-Player or PlayStation3 - to be able to playback
The BD-encoded DVDs can be play-backed IF Mac also have Roxio DVD-player tool. Not on any standard Mac or DVD-player
Full BD-disks needs a BD-player (in Mac) as they need blue-laser to be read. No red-laser can do this.
• HOW much free space is there on Your internal (start-up) hard disk. Go for approx. 25Gb.
less than 5Gb and Your result will most probably not play.
• How it was recorded - Tripod vs Handheld Camera. A stable picture will give a much higher quality
• Audio is most often more critical than picture. Bad audio and with dropouts usually results in a non-viewed movie.
• Use of Video-editor. iMovie’08 or 09 or 11 are not the tools for DVD-production. They discard every second line resulting in a close to VHS-tape quality.
iMovie 1 to HD6 and FinalCut any version delivers same quality as Camera record in = 100% to iDVD
• What kind of movie project You drop into it. MPEG4 seems to be a bad choice.
other strange formats are .avi, .wmv, .flash etc. Convert to streamingDV first
Also audio formats matters. I use only .aiff or from miniDV tape Camera 16-bit
strange formats often problematic are .avi, .wmv, audio from iTunes, .mp3 etc
Convert to .aiff first and use this in movie project
• What kind of standard - NTSC movie and NTSC DVD or PAL to PAL - no mix.
(If You need to change to do a NTSC DVD from PAL material let JES_Deinterlacer_3.2.2 do the conversion)
(Dropping a PAL movie into a NTSC iDVD project
(US) NTSC DVDs most often are playable in EU
(EU) PAL DVDs most often needs to be converted to play in US
UNLESS. They are play-backed by a Mac - then You need not to care
• What kind of DVDs You are using. I use Verbatim DVD-R (this brand AND no +R or +/-RW)
• How You encode and burn it. Two settings prior iDVD’08 or 09
Pro Quality (only in iDVD 08 & 09)
Best / High Quality (not always - most often not)
Best / High Performances (most often my choice before Pro Quality)
1. go to iDVD pref. menu and select tab far right and set burn speed to x1 (less errors = plays better) - only in iDVD 08 & 09
(x4 by some and may be even better)
2. Project info. Select Professional Encoding - only in iDVD 08 & 09.
Region codes.
iDVD - only burn Region = 0 - meaning - DVDs are playable everywhere
DVD Studio pro can set Region codes.
1 = US
2 = EU

What it turned out to be was the "quality" settings in iDVD. The total clip time was NOT over 2 hours or 4.7GB, yet iDVD created massive visual artifacts on the "professional quality" setting.
I switched the settings to "high quality" which solved the problem. According iDVD help, "high quality" determines the best bit rate for the clips you have.
I have NEVER seen iDVD do this before, especially when I was under the 2 hour and 4.7GB limits.
For anyone else, there seem to be 2 places in iDVD to set quality settings, the first is under "preferences" and the second under "project info." They do NOT seem to be linked (i.e. if you change one, the other is NOT changed). take care, Mario
TO GET IT TO WORK SLIGHTLY FASTER
• Minimum of 25Gb free space on Start-Up hard disk
• No other programs running in BackGround e.g. Energy-Saver
• Don’t let HD spin down or be turned off (in Energy-Save)
• Move hard disks that are not to be used to Trash - To be disconnected/turned off
• Goto Spotlight and set the rest of them under Integrity (not to be scanned)
• Set screen-saver to a folder without any photo - then make an active corner (up right for me) and set
pointer to this - turns on screen saver - to show that it has nothing to show
Yours Bengt W
