Increasing image resolution in iphoto

How do I increase the resolution of my images in iphoto? I want them to be at 300 dpi instead of 72 dpi. I shoot in jpeg. I don't have a "tools" icon at the top of my screen.

Welcome to the Apple Discussions. 300 dpi only comes into play when you want to print the photo. What are the pixel dimensions of your image? Divide them by 300 and you'll get the print size you can achieve at 300 dpi. iPhoto just reports the display resolution which is 72 ppi, pixels per inch.
If you print the same picture at 8 x 10 and 3x5 you'll get two widely different resolutions.
You can find out more about that in The Myth of DPI.

Change the image resolution through iPhoto

Does anyone know how to change the image resolution through iPhoto? I know it can be done in other image editing software, but I have yet to find it as an option in iPhoto.

Hi Rachel,
There is no option within iPhoto.

Where do I find the image resolution in iPhoto '09

Where do I look in iPhoto '09 to find the resolution of a photo?

Are you referring to the "dpi" setting for the image? That's not relevant until you set a print size. DPI is dots per inch so you need to divide the width of the image in pixels (dots) by the width of the print (inches) to get the resolution of that print.
This will give you more info on that: The Myth of DPI.
Many cameras will set the dpi in the metadata at 180 dpi. iPhoto changes it to 72 dpi as that's generally the screen resolution of many monitors. But as described above it's meaningless until you go to print the image.

How do I increase image resolution?

Not sure what the reason is but when I add photos to a group chat they're the size of the average stamp making the subject of the photo completely unreadable. Is there any way to increase this?
Bandwidth is definitely not an issue for me or anyone involved in the group chat.

Hi,
You may change the Resolution using the HP Scan application as following:
Click HP Scan at the top and then click Preferences.
Within the launched windows select the required Resolution.
close the Preferences window and perform the scan.

How to increase the image size without losing resolution in iPhoto?

Dear All
I have pics i took with my phone which is not an iphone, just little sony ericsson phone.
Is there a way to increase the image size without losing resolution in iPhoto please? Or cheap 3rd party software or shareware perhaps?
thank you very much.

iPhoto has no way to do that. You'll need an external editor for the job. Not all have the capability. I know Photoshop has.
You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.

Iphoto says that my image resolution is to low?

Iphoto says that my image resolution is to low, but my resolution is fine at 800 x 800 at 300 dpi... is this still to low....?

Welcome to the Apple Discussions. Too low for what? Is this for a print, book, calendar?
The resolution iPhoto is requiring is shown in iPhoto: Minimum Picture Resolution For Ordering Quality Prints. Basically the important number is the number of pixels in the length and width, dpi aside.
So your image is 800 x 800 pixels. A 4" x 4" picture would give you 200 dpi. For a 6 x 6" picture that would drop down to 150 dpi, etc.

Image resolution after cropping

When I zoom in on a 4 megapixel image the screen shows an image with acceptable resolution. If I crop to an image the size of the one showing in the unconstrained mode the image resolution drops dramatically. How can I crop and not loose so much resolution? I've been able to do much better with editing in Elements and then importing the image back into iphoto.

Welcome to the Apple Discussions. Even though the dpi has changed from what it came out of the camera to 72, the resolution has not changed. It's just a different way of expressing the total number of pixels and the size to be printed. It's just math.
A 1600 x 1200 image at 300 dpi will print a 1600/300" x 1200/300" print (you do the math). That same image at 72 dpi will produce a print that is 300/72 times larger. The number of pixels, 1600 x 1200 hasn't changed, just the size to be printed. iPhoto changes it to 72. I've checked files with Photoshop, imported to iPhoto, exported and rechecked and the dpi has dropped whereas the print size has increased.

I imported 635 images into an iPhoto album so that I can share them via a photo-stream. However, iPhoto says there are only 600. When I try to add the missing images it says they are already there. Why can i not see these images in iPhoto?

Generally I would not use Facebook for sharing any photos, it compresses the photos substantially, and when you have shadows and dark colours you get visible "bands" where there should be subtle gradients, ie at sunsets and sunrises.
It sounds like you are using two methods to upload to Facebook:
1. Sharing from within Aperture, which basically syncs Facebook with your Aperture album, so any changes made at either end gets synced, hence the deletions from Albums, although the original file should still be in your library, just removed rom the album. It is like a playlist in iTunes.
2. Exporting pics and uploading to Facebook from the browser.
I am not sure how method 1 gets compressed, but I know that uploading hi-res jpegs to Facebook using method 2 results in poor quality images.
I wouldn't even bother comparing option 1 or 2, and they will both be poor images once you view them on Facebook, as opposed to viewing uploaded images on proper image sharing / hosting sites.
Your problem is not with Aperture, it is using Facebook for showing your work.
If you export pics form Aperture at high res jpegs or TIFFs your images will be fine.
If you insist to use Facebook as your way to share your work, then your workflow should be this:
1. Right click images you want to share.
2. Select Export version.
3. Export as 100% size and ensure the export settings are set at 100% quality.
4. Upload this pic into Facebook.
This will get you the best image size and resolution on Facebook.
See how you go.

Importing raw images (.CR2) into iPhoto'08

I am trying to import 17Gb worth of raw (.CR2) images from an external hard drive as JPEGs, but in iPhoto I find I have to import them first before I convert them to JPEGs. Does anyone know how I can import them into iPhoto as JPEGs or tell me of a software that can convert them without importing the photos first? (Keep in mind that this software needs to be *leopard friendly*.)
Thanks, Supernova329

Supernova329:
There is a way to batch convert the cr2 raw files to jpgs with the demo version of iView MediaPro. Launch iVMP and import your folder(s) of raw files. Then select a folders worth of file and use the Action->Convert Image files menu option. In the settings select JPG as the format, Size=use image size, Settings=color =best, and Resolution=use image resolution. Then hit the Convert button and pick or create a new folder to put them in.

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.

Can I increase the resolution in a jpg created from an imovie clip?

Can I increase the resolution in a jpg created from an imovie clip? I've done the steps to create/extract a "still" from an iMovie clip (which started as a small clip in iphoto). I did the steps of creating the freeze frame, and then doing a "screen shot", but the resolution is only 97 kb, so it won't be good to print. Help!

Poor resolution on iPhoto book

I just ordered the large softbound iPhoto Book from Apple and am very disappointed with the poor resolution of the photos. My original files were 1280x960. Is there any way to find out if my photos are being uploaded at the highest possible res? I've read other posts about changing preferences, but haven't been able to figure out how to do that at my end.
Thanks!

Emily:
The easiest way I've found to modify preference files is with Pref Setter. Once you've located and opened the iPhoto preference file do a search for "dpi". Then change the values for the Keys BookTargetImageDIP, BookTargetSmallImageDIP and BookTargetMediumImageDIP to 300. Save and close Pref Setter. That's it.
It's interesting that you found the large book images to be poor. There was another user that received large books from both the east and west coasts. He found the east coast book to be of lower image resolution (greater halftone pattern) than that from the west coast. All of my large size books have come from the west coast and have been very good, with or without the resolution change in the preference file. Not so with the medium size books. There were patterned no matter what resolution was set in the preferences.
Good luck.

How to increase image size?

I am trying to put a collection of images onto a photo library and I need the image to be higher than 24mb. how do I increase the size of my images?

Do you really need to increase the file size and not the resolution (in pixelsize)? Increasing the file size will not increase the resolution or quality of your image. If you want to change the file size of an image, export it and pick one of the export presets that generate a high resolution image, for example "Tiff, original size, 16bit"" will waste a lot of disk storage. If that is still not large enough, edit the preset -duplicate it and set the size to " xx bx yyy inches"; then pick a very high dpi value, for example 1000dpi.
But if you meant: high pixelsize - pick an export preset with "fits within ... pixels"

Merge to HDR Pro from Lightroom changing image resolution

Image resolution in PS from a RAW LR transfer is 300ppi but I notice today the final HDR image from a LR transfer of three files is 240ppi. My preference in PS is set to 300ppi and I don't find a way to set a HDR resolution preference. I want my final HDR image to be 300ppi - how do I get this?

Does turning off »Use Graphics Processor« in the Performance Preferences and restarting Photoshop have any bearing on the issue?
Have you tried both reducing and increasing the Memory Usage in the Performance Prefences?
I tried to work on the exposition of the three photos, but that didn't work.
What does this mean?
Are you using actual bracketed shots?
