Firstly - you shouldn't copy and paste from photoshop. You should save your image as a psd/tiff and then use File>Place to bring the image to InDesign.
Secondly - how images look in InDesign is neither here nor there
Check the Window>Info panel
Select the image and there are two readings
The former gives the actual reading of PPI from the original file.
The latter gives the reading of the PPI of the image after it's placed, at the percentage it's placed at - basically giving you the accurate PPI for output.
What's the image PPI in Photoshop?
I'd like to qualify my first point "Firstly - ... "
You should save as a PSD or TIFF is purely only Raster elements.
If you have live text layers, vector shapes or vector masks - then save as Photoshop PDF.
First of all, thank you for your reply. I just checked an example image and both are 72 dpi, in InDesign as well as in Photoshop. I even created a document for web in InDesign, using the 'web' & digital publishing option (which is 72 dpi) and placed the same image. At 100% pixelated, when resizing to 75% crisp. I don't know what to do..
The thing is.. I've never had this problem for years.. with importing images. Did I change settings or?
First one is Photoshop, second in InDesign (top left is import at 100%, bottom right is import resized to 75%). In case images are too small to see, full size: http://justinwust.com/photoshop.jpg & http://justinwust.com/indesign.jpg
So what are the effective ppi readings in ID?
Keep in mind, too, that in ID even with High Quality display performace you are looking at a compressed jpeg screen preview, not the actual pixels as you are in Photoshop. How does it look in a PDF?
