# Import image, made it smaller, then enlarged, lose quality?

I imported photoshop images to indesign.

Then I made images smaller in indesign, but I decided to enlarge images.

Are these images become lower quality?

You need to check out the Window>Info

There are two values

1) Actual

2) Effective

With Actual it refers to the amount of PPI the image has when placed at 100%

With effective - it refers to the amount of PPI the image has when scaled.

For example:

An image that is Actual 72 PPI when placed at 100% is 72 PPI

If you scale that image to 24% the Effective PPI is 300 PPI

Math:

72/24*100 =  300

Conversely

If you place an image at 100% and the Actual PPI is 300

If you scale the image up - to say 150% then the Effective PPI is 200 PPI

300/150*100

So if I made 50%, then decided to go 85%, if I don't go bigger than 100%, quality won't be lower.
