What do you set your foundation with?

I'm obsessed with the ambient lighting powders, I've been using them since they came out and haven't been satisfied with anything else ever since. They're pretty amazing and I could use them for the rest of my life but I also like switching it up sometimes however I feel like other powders just sit on my skin and you can obviously see them and that tends to make me look cakey. 
Do you have any favourites? Preferably ones that give you that photoshopped skin look.
