Changing resolution to 72 dpi using iPhoto
My daughter is in a photography club and she's entering a photo contest. One of the requirements is that all photos must be 72 dpi. Her teacher uses Photoshop and isn't familiar with iPhoto, so he doesn't know how to tell her/us what to do. Any help?
Hi, Bearcat Annie. There are two problems here: 1) iPhoto 4.0.3 and earlier versions don't offer any direct way to change the dpi specification of an image, and 2) the teacher's dpi requirement has no meaning unless it's accompanied by an overall resolution limit, such as 640 x 480 pixels, 1024 x 768 pixels, etc. Has the teacher specified an upper resolution limit?

Change resolution based on dpi in flex
Hi All ,
In my Flex Application , i am getting image for chart / process from java. Its working fine.
Now my new requirement is :
1) For the first time when getting image the default dpi should be : 72dpi
2) And i should have 2 more options to select 90dpi and 150dpi in flex
and when selecting these dpis , my chart/process resolution should change based on selected dpi in Flex.
Please helpp.....SkR Pasha,
If I understand what you mean, there are two approaches you can take:
1) The easiest way is to just define 3 paths to images, each one being a different resolution:
var img1:String = lowResImage.gif;
var img2:String = medResImage.gif;
var img3:String = highResImage.gif;
Then load the one that is appropriate when the DPI changes.
2) Flex 4.5 includes support for multiple DPIs. First you get the current DPI:
FlexGlobals.topLevelApplication.applicationDP
Then you use the MultiDPIBitmapSource class to specify which image to use based on the DPI.
Here's an example that you can apply to a standard application (you don't need to write a mobile app to do it):

Mac Mini and LCD TV, changed resolution and now cannot use the screen anymo
hello,
I have a Mac Mini and and LCD TV which is connected via HDMI cable. I was playing around with the resolution settings (not very smart in hindsight) and managed to select a resolution that my TV does not support. I do not have another monitor or Macbook. Is there anything I can do to reset the resolution settings? I tried to reset the PRAM, but that didnt seem to solve the problem. I also tried starting in Safe mode but that didnt do the trick either.
Appreciate your help!Arie, it may be possible to get to System Preferences via the keyboard. But you have to be sure the Finder is the foreground application. Is your Mac set to boot straight into your account or does it pause waiting for a password? If it boots straight into a user account, you can try the following procedure:
\- Restart the Mac (It should be hooked up to the misbehaving display in case that's not clear)
\- When it is done booting, type Cmd-Tab and then Cmd-Q. Do this several times. (Cmd-tab will step the Mac through all the programs that might be running. Cmd-Q quits them. Doing this several times ensures that only the Finder is running since the Finder can't be quit. This is important for the next step)
\- Type Shift-Cmd-a (This should open the Applications folder)
\- Type "sys" quickly (System Preferences within the Applications folder should now be highlighted)
\- Type Cmd-o (This should open System Preferences)
\- Type out the word "screen settings" completely (This should cause Displays to be highlighted in the System Preferences main panel)
\- Hit the Return key (This should open Display Preferences)
\- Hit the Return key again (This will clear any alert box that may have popped up)
\- Hit the Tab key once (This will shift the keyboard focus to the resolutions list)
\- Now start using the up (or down) arrow on the keyboard one press at a time. Each press of the arrow key moves to the next resolution in the list. Wait at least five seconds between arrow key presses for the resolution change to take effect. Hopefully, at some point, the monitor will light up with a stable image and you are back in business. -
IPhoto resolution at 72 DPI after editing
Hi,
Can anyone help me keep my high-resolution jpegs at 300 DPI, as imported from my Nikon D80? Whenever I apply any editing changes to the photos, the resolution changes to 72. I've already changed the Photo Book Order export resolution to 300 DPI using PrefSetter. Can I change a setting somewhere in iPhoto to keep my resolution high? Help! Thanks!istratmusicom:
Welcome to the Apple Discussions. Not to worry. It's just a numbers game. A 1600 x 1200 photo at 72 dpi will print a 22" x 16.6" print. If that same file is set to 300 dpi the print size will be 5.33 x 4 inches. iPhoto just chooses to reset the dpi to the screen resolution. That will not affect the printing of the photo in the book. The dpi of any file will vary according to the size of the frame on the page that it's placed in. See this site for a better description:The Myth of DPI.
What was the setting of the export resolution before you changed it to 300 with PrefSetter? The default dpi for iPhoto 7 is 300 for all sizes of books and 170 dpi for the low res warning flag.
Happy Holidays
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. -
How do I resize/change resolution of photos from iPhoto when used in iWeb
I am shooting with a 7.1 Mega Pixel Canon to get enough quality to crop and print high quality pictures of my baby daughter and her adventures in the world.
I have a website up made with iWeb, but when I select the photos in iPhoto and go Share / Sent to iWeb / photo page - I get a nice layout of the photos but at full resolution when the thumbnails are selected or the slide show is run. Although nice and sharp, this is a pain for anyone looking at the site even with high speed access.
There must be some way to resize photos, but I have yet to figure that out with iPhoto, let alone iWeb. And as one photo at a time is a pain, there must also be a way to rescale a whole selection of photos that I want to use for a page - say her Disneyworld trip. I can't be the first person to run into this, but I have not found anything out there to point me in the right direction.
Ideally I wold like to create a resized set from the originals - so I can still print and crop in high qulity. I also am not really sure what resolution would be best or easy viewing and download - that's probably subjective. 1200x800 comes to mind but I am open to suggestions.
Perhaps resize is not the right term - changing resolution is probably more accurate, but there too I have not found an answer.
Appreciate the help and suggestions.dan28088,
Tried your site on two different browsers, using highspeed broadband; the site is, indeed, extaordinarily slow. We can dissect the thing down to the last file, but it won't change anything, as far as I can see. If it were me, I would host the site on another server. The .Mac servers are just plain slow, period. I think that is the primary problem here. Just my opinion, others may disagree.
I created a new site this past weekend for a new project, and published it to .Mac. It contains a lot of jpeg files in slideshows (along with the usual png suspects!) . After reviewing it a few times, and not being satisfied with page-load speeds, I published to a folder and uploaded the site to space on 1&1 WebHosting.
The page-load speeds TRIPLED. That's right...3X as fast page-load speeds. Even large, linked to files, 3MB+, load within a reasonable amount of time. (seconds)
I still will keep a .Mac subscription, as I like and use all of the other features of the iDisk. But for serious website hosting, I think you will be better 'served' with a remote host. Your money with .Mac is certainly not wasted; the syncing services and other features of iDisk space that integrate with your local files are well worth the yearly fee. Again, only one user's opinion, based on experience.

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!!!
ThanksWhat 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.

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?
ThanksWith 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.

Using Thunderbird 31.4.0 on Win7 Professional with full Admin rights. It seems that all jpeg files larger than 50 KB (or maybe even smaller) are automatically altered from their original resolution of 300 dpi (or higher) to 72 dpi, both outgoing as well as incoming. I have tried unchecking and checking the "Display Attachments Inline" checkbox in the View menu but this does not change the behavior.
In the Config Editor, the setting 'browser.enable_automatic_image_resizing' is set to False. In addition, the setting 'image.high_quality_downscaling.enabled' is also set to False. Please help!
Thank you!Yes, fortunately, I am a Windows user, but I don't want to start a religious war here And it is also possible to run multiple versions of Adobe products simultaneously under Windows - why shouldn't that be possible? Currently I have CS3 and CS4 and somtimes use CS3 when CS4 is just too buggy to get the job done. Before that I had CS and CS2 on the same machine.
But I wouldn't keep all versions back to PS 6.0 or CS, that would be a bit too chaotic and I'd had to spend days of installing if I get a new computer. I expect those programs to be a little bit backwards-compatible, so I don't have to use many different versions. And for Photoshop, this is mostly the case. It's just very tiny details like Smart Object resizing that seems to work differently.
Otherwise I'm really happy that in CS4 I can finally link Masks to smart objects and apply warp and perspective on them, that's a big plus! -
I would appreciate it if someone could advise me as to the optimum resolution, dimensions and dpi for actual photographic slides that I am scanning for use in a Keynote Presentation, that will be projected in a large auditorium. I realize that most projectors in auditoriums that I will be using have 1024 x 1200 pixels, and possibly 1600 x 1200. There is no reference to this issue in the Keynote Tutorial supplied by Apple, and I have never found a definitive answer to this issue online (although there may be one).
Here’s my question: When scanning my photographic slides, what setting, from 72 dpi to 300 dpi, would result in the best image quality and use up the most efficient amount of space?
Here’s what two different photo slide scanning service suppliers have told me:
Supplier No. 1 tells me that they can scan slides to a size of 1544 x 1024 pixels, at 72 dpi, which will be 763 KB, and they refer to this as low resolution (a JPEG). However, I noticed when I looked at these scanned slides, the size of the slides varied, with a maximum of 1.8 MB. This supplier says that the dpi doesn’t matter when it comes to the quality of the final digital image, that it is the dimensions that matter. They say that if they scanned a slide to a higher resolution (2048 x 3072), they would still scan it at 72 dpi.
Supplier No. 2: They tell me that in order to have a high quality image made from a photographic slide (starting with a 35 mm slide, in all cases), I need to have a “1280 pixel dimension slide, a JPEG, at 300 dpi, that is 8 MB per image.” However, this supplier also offers, on its list of services, a “Standard Resolution JPEG (4MB file/image – 3088 x 2048), as well as a “High Resolution JPEG (8 MB file/image – 3088x2048).
I will be presenting my Keynotes with my MacBook Pro, and will not have a chance to try out the presentations in advance, since the lecture location is far from my home, so that is not an option.
I do not want to use up more memory than necessary on my laptop. I also want to have the best quality image.
One more question: When scanning images myself, on my own scanner, for my Keynote presentations, would I be better off scanning them as JPEGs or TIFFs? I have been told that a TIFF is better because it is less compressed.
Any enlightenment on this subject would be appreciated.
Thank you.When it comes to Keynote, I try and start with a presentation that's 1680 x 1050 preset or something in that range. Most projectors that you'll get at a conference won't project much higher than that and if they run at a lower resolution, it's better to have the device downsize your Keynote. Anything is better than having the projector try and upsize your presentation... you work hard to make it look good, and it's mangled by some tired Epson projector.
As far as slides go, scan them in at 150 dpi or better, and make them at least the dimensions of your presentation. Keynote is really only wanting 72dpi, but I do them at 150, just in case I need to print out the presentation as a handout later, and having the pix at 150 dpi gives me a little help with their quality on a printer.
You'd probably have to drop in the 150 versions again if you output the Keynote to .pdf or Word or something, but at least you have the option.
And Gary's right (above) go ahead and scan them as TIFFs. Sooner or later you'll want to do something else with these slides (like make something for an iPad or the like) and having them as TIFFs keeps your presentation looking good.
Finally, and this is a big one, get to the location for your presentation ahead of time if you can, and plug the laptop in and see what you get. There's always connection problems. Don't let the AV bonehead tell you everything will work just fine ('... I don't have any adapters for a Mac...') . See it for yourself... you're the one that's standing up there. Unless it's your boss, then you better be really sure it works. -
I try to open iphoto and it comes up with You have made changes to your photo library using a newer version of iPhoto. Please quit and use the latest version of iPhoto. I have downloaded photo manager and it's telling me to update but it wont update...
iPhoto is Apple's included program to manage your photo's and pictures.
It receives updates over time with Software updates and new machine or iLife purchases.
When iPhoto gets updated or a newer version is used, it may alter iPhoto support files, but newer iPhoto versions usually always compatible with older files which it then updates.
If you used a newer iPhoto on your iPhoto support files, then they got altered to the newer format, older iPhoto versions can't read the older format.
Somewhere along the line you somehow got a older version of iPhoto on your computer, you need to fine the newer version of iPhoto (not this photo manager, sounds like another program)
Or somewhere along the line you used a newer iPhoto version (like on another Mac) and it altered the iPhoto support files on your older version of iPhoto.
So the key here is to find the newest version of iPhoto and use that to access your iPhoto support files.
If you didn't access your iPhoto support files from another Mac, then you should have the newer iPhoto version on your computer.
Once you find it, and get it in the Dock, you should remove the older iPhoto version from your computer to prevent this from happening again.
Lastly, if the newer version of iPhoto is somehow gone off your computer, you should be able to get a copy off the latest OS X install disk or iLife using a free program called Pacifist.

Then you need to check for updates for iPhoto in the program itself, the current version is 9.1.2 -

When opening the version of Iphoto i have an error message appears that says; You can't open your current iphoto library using this version of Iphoto. You have made changes to your photo library using a newer version of iphoto. Please quit and use the latest version of iphoto. What? If I can't open the current library using the latest version of iphoto, and I am asked to make changes the the newest version!!! I'm asked to run in circles chasing my tail...I had a new hard drive installed about 6 weeks ago. I am running MAC OS 10.5.8
What version of iPhoto do you have? If you're on 10.5 then you're not running the latest iPhoto
Any chance that the library was opened with another version?
Simplest solution will be to just restore from your back up. -
you can't open photo library using this version of iphoto. you have made changes to your photo library using a newer version of iphoto. please quit and use latest version of iphoto. iphoto 11 is installed.
This is a message you got?
If so, as your post isn't clear, it may be a bogus message caused by a corrupt database.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

Opening iphoto I get an error message that says "you can't open your current photo library using this version of iphoto. You have made changes to your photo library using a newer version of iphoto. Please quit and use the latest version of iphoto." I wouldn't have a clue as to how to change to a new version of iphoto even if I wanted to.
If you don't have a backup you can resort to give this a try:
Starting over from scratch with new library
Start over with a new library and import the Originals (iPhoto 09 and earlier) or the Masters (iPhoto 11) folder from your original library as follows:
1. Open the library package like this.
2. Launch iPhoto with the Option key held down and, when asked, select the option to create a new library.
3. Drag the subfolders of the Originals (iPhoto 09 and earlier) or the Masters (iPhoto 11) folder from the open iPhoto Library package into the open iPhoto window a few at a time.
This will create a new library with the same Events (but not necessarily the same Event names) as the original library but will not keep the metadata, albums, books slideshows and other projects.
Note: your current library will be left untouched for further attempts at a fix if so desired.
