Is the following sentence grammatically correct in the sense of the usage of infinitive "to"
" To see the scene, I was shocked."
meaning, When I saw the scene, I was shocked.
I understand, usually in this type of sentence, we are supposed to use gerund ;
"Seeing the scene, I was shocked."
If the sentense above is grammatically correct, is that the same usage as
" To be frank with you, it was my fault."
Please explain out to me.
