Portfolio Help

Hi,
I am trying to figure out what is the best way to shrink my portfolio from 150 mb without reducing the resolution too much.
Any ideas?

Firstly, when you export it choose press quality. What size is it after that?

i found that by placing each final page into a indesign doc and making a pdf like that (especially print to pdf) made v light pdfs.
you can also experiment with pdf quality as goldie said
