How can I maintain resolution of 300 dpi when I enhance a an image file in Iphoto? Whenever I modify an image and burn to a cd my dpi drops to 72 dpi. Help!

Chuck Wehner - Dec 11, 2005 - 7:30 pm

First off, I would like to ask you where are you getting a read out of your dpi on your images. Is it in iPhoto or in some other application?

Photos are usually not described as having a particular dpi but rather a resolution such as 640 x 480. DPI is usually something that relates to a printer or scanner.

chuck: thanks for taking my question. I am a photographer with limited computer skills, however my typical situation calls for shooting a job and putting the images in iphoto under a given file name. Then I select a particular photo and highlight the image and go to the share box. Under that heading you can pick "burn cd" of that image. After the image is burned, I take it to be printed. All of of my images so far have read 300 dpi when viewed in iphoto. The other day I tied to have a Christmas card printed of a photo which I enhanced with the "adjust" tool and when I took it to the lab, the image read as to low on resolution at 72 dpi and not printable. I got the dpi reading under the tools box heading.

Bill,

I'm a computer user with advanced photographic skills so between the two of us we should be able to figure this out.

My version of iPhoto 4 doesn't have a Tools Box heading, what information do you get on a photo when you do a "Command-I" or Show Info from the menu bar? (when I do that on one of my photos I get 1280 x 960 pixels)

I also do not have a Share Box in my iPhoto but that may be your problem, usually when you share it means you are sharing over the internet which typically means 75 dpi in order to make the image small enough that it doesn't take all day to load.

Can you just click on your image and instead of going to the share box go to the burn image icon and burn you image to a CD?

Chuck: It sounds like our iphoto software is a little different. The only way I can burn a CD from iphoto is using the share box or I can use toast 6 titanium program. It has been so long since I used the "toast" program I find it it little more difficult. The thing that baffles me is that if I don't adjust the photo any I can maintain the 300dpi with no problem. I even went to the e-mail setting and changed the resolution to its highest setting to see if that affected the outcome. It didn't change anything. Oh well!

Bill,

What version of iPhoto do you have? You can find out by going to one of the menu bars and selecting "About iPhoto" also what version of OS X do you have? You can find that out by going to the Apple menu and selecting "About this Mac".

You can also burn directly from the finder without using toast. Oh and another thing try going to the Help menu in iPhoto to see if you can find any information on how to burn your photos.

Chuck: I have iphoto 5 version 5.0.4(263). My system is OXS 10.4.2. I went to finder and I need some help navigating from there. I haven't tried the help box in iphoto yet, but I will. Bill

Chuck Wehner - Dec 12, 2005 - 8:22 pm

Bill,

OK, that explains our problem. My version is actually older than yours so I can't recreate or test your problem of lower dpi after editing your photos.

I'm going to put you back in the question pool to see if someone else with your version of iPhoto can help.

In the future when asking for help please give more information such as your OS and application version.

Bill,
Not sure why they are going at 72DPI, but try this.

Create a new folder on your desktop.

Now, in iPhoto, select the pictures you want to burn, and then go to Share->Export.
When the new window pops up make sure the 'Format' is set to Original,
Size = Full Size Images
and then you choose how you want them named (filename, album names), etc.
I always click on 'use extensions' as well, then it will append the .jpeg or whatever the case may be.
Now click on Export, and then select the new folder you created on your desktop.
I had you create the new folder because, if you don't put them in a folder.. they will just be all over your desktop.. and that would clutter the desktop if you had exported a bunch of them.

These will be the full size original images.

Let me know if this helps!
Thanks,
-Jonathan

Jonathan: I tried your directions but still no change in solving the dpi resolution problem. What is interesting is that I can take an image that has been enhanced and make large prints on my computer printer(HP 7350) and get decent quality on 81/2x11 paper.However it becomes a problem after burning to a CD and getting it printed at a commercial lab.

one1step1 - Dec 16, 2005 - 1:24 pm

Maybe we are confused about resolution and DPI.
Are you images the correct resolution (example: if your camera took them at 1429x258, that would be the resolution, not the DPI.

let me know what you think.

bill mahan - Dec 16, 2005 - 4:37 pm

Jonathan: Currently my images are averaging 3000x2000 pixels, and are running 1.5 to 3.0 MB size files.I shoot mainly large file pictures in the normal to fine setting on the camera(Nikon D100). I have made large 16x20 size prints at labs when I didn't enhance contrast, color etc. without losing detail. To be perfectly honest I still have trouble understanding resolution verses dpi, when labs tell me that a photo won't print at 72 dpi and should be at 300dpi. I guess I need to start reading some books on the subject.
