Drupal 8 views-view-field.html.twig - twig

Question

this is going to be quick and direct. I'm trying to access different content results from a view related with a content type. I'm pretty much a newbie with twig, but I did make it work to access fields.
Example:
Content Type: Books
Fields: Name, Portrait(Image). Machine Name: field_name - field_image
Let's say I upload 2 contents called Book 1 and Book 2 based on the content type.
What I want is to display all fields from Book 1 for the moment or Book 2 but not all of the content at the same time.
My effort:
First attempt: tried this line of code
<h2>{{view.field.field_name.getvalue(view.result[0])}}</h2>
Works perfectly, it prints index 0 but not working printing the image, because instead it gives me the id.
Second attempt: tried this line of code:
{{fields.field_image.content}}
This one seems to be the most practical, it works showing the actual picture from the field image, but I dont know how to access only the image for one index(Book 1).
Third attempt: tried this line of code
{{content.field_image.0}}
This one doesnt work for me at all.
Hopefully somebody would help me with this. I've been struggling one week with this.

You can turn on Twig debugging, then do a dump to see how things are structured.
https://www.drupal.org/docs/8/theming/twig/discovering-and-inspecting-variables-in-twig-templates
Or perhaps look at the Twig Tweak module that gives a lot of great functions that might suite your needs:
https://www.drupal.org/docs/8/modules/twig-tweak/cheat-sheet-8x-2x
This one in particular might be good since you have the ID in your first example:
{# The argument can be FID, UUID or URI. #}
<dt>Image:</dt>
<dd>{{ drupal_image('public://ocean.jpg') }}</dd>
