Prepositions

[maggyaf]

Hello!

My name is Maggy, I'm an English teacher from Buenos Aires, Argentina.

I would like to ask for your help.

Please, in the following sentence, which is the correct preposition?

"I was surprised at/by how much I enjoyed using the cameras"

I think the correct one is "at", but another English teacher said that I was wrong and that the proper one is "by".

I thank you in advance for your kind help.

Both are correct, but "by" is the most typical and usual.
