写真で見たのと同じ風景だったって英語でなんて言うの？

It looked the same as in the brochure/tourist guide etc would be another way of saying this

If the place looks like the photos you have seen before, then you can say 'it was just like the photos' or 'it was exactly like the photos'. You can also say 'it was exactly how I imagined' - meaning you had seen pictures so you built up an image in your head and when you finally saw it, it was what you had pictured.

Sometimes when you see a photo of something it doesn't always look the same in real life or when you actually go there so to say that it looked like the photos you can say 'it look exactly like the photos', or 'it looked just like the photos' when you see a photo you imagine what it will look like so can also say 'it was just as I imagined it would be'

A picture perfect situation is when something has no flaws and is exactly as expected, desired, hoped for or imagined....(just like a perfect picture ;-D) The vistas were picture-perfect it was totally amazing to see...

If you went on vacation to a place you had only seen in photos before,and want to explain that it was very beautiful just like the photos, then one of the above suggestions may suffice.

When you want to explain that a place that a person had only seen in pictures is just as beautiful as it is in the pictures, then you may express it in the following ways: -It's as beautiful as it is in the photos -It was as beautiful as you have seen in the pictures

You could say something along the lines of 'It was so beautiful, it looked just like the photos I have seen' - This is a good way to express joy and happiness that you feel when you are in the place you dreamed about going to.
