How do I find the dpi of an iPhoto?
MacBook Pro, OS X Yosemite (10.10.4), Lion, then Mavericks, now Yosomite
The photos in iPhoto do not have dpi assigned. They are just a matrix of pixels and have a pixel width and pixel height.
When you export a photos from iPhoto it will create an image file that may have dpi assigned. You can see the dpi values when you open the exported photo in Preview and open the Inspector from the Tools menu. For example, this photo has been exported with 180 dpi. But more important than the dpi is the pixel size. It will tell you the quality of the photo.
léonie - thank you for the duck photo and explanation. I always thought photos consisted of pixels that are a square inch each. Maybe the converter will help as it seems so complicated.
As you can see I followed your suggestion of looking for the dpi info. in Preview. How can I change this to 300 dpi?
The pixel dimensions need to be 2400X2700 for a minimum 300 DPI print.
8"X300 = 2400
9"X300 = 2700.
