Actual & Effective PPI in InDesign


Embarrassed to ask this question, I am not an expert at any software packages, just taught myself InDesign to do my CV and portfolio for a job vacancy. Anyway I have completed adding photos to my portfolio. Now I am trying to understand the Pixels Per Inch (PPI) of the images so when I email it across as a PDF the recipient can see it clearly. The PPI of my photos all vary as I have increased and decreased their sizes. What do I do?

The effective PPI of each image in an InDesign document is located in the Link Info section of the Links Panel.

The panel will show both the actual PPI and the effective PPI once the image is scaled.

In this example the original image was 300 PPI and was scaled to 75%, thereby increasing the effective PPI to 400.
