How to Find Out Who Photographed a Campaign

Q:

Is there a way to know who photographed a campaign? For example, if you see an inspiring campaign and you want to connect or follow the photographer who worked on it, how can you do that? 

A:

I used to use this website: https://www.adsoftheworld.com, but these days, Google Image Search may be the quickest way. 

-Does anyone else have ideas/suggestions for this?
