How get info fields when Override template on Drupal 8

Dear drupaler,
I've a problem that don't understand how solve, I've search it in all the web but really nothing to help me found,
I'll try to explain it.

PRE: I've a Mac and MAMP and Installed Druapl 8 via composer.

I made a view with personalized fields like title, image, and more information (this works fine), now I would to override the output of
fields for example I use core/modules/views/templates/views-view-field.html.twig and override it as views-view-field---[view machine name]--[view display id]--[field].html.twig (workaround works),
now would like combine to build a HTML code and TWIG code in a TWIG file, the file that contains {{ output -}}.

I've installed DEVEL with KINT submodules and when I use kint(output) the system getting to me HTML rendered result,
Into the head of file I reading:
* Available variables:
* - view: The view that the field belongs to.
* - field: The field handler that can process the input.
* - row: The raw result of the database query that generated this field.
* - output: The processed output that will normally be used.

If I try to kint(field) the system getting to me ERROR 500, I found the solution to set Kint::$maxLevels = 6;
and upgrade maximum_memory_limit to 1024MB (now kint() works).

Good!! when launch kint(field) a lot of information show to me , but I don't found the basic infos to build HTML and TWIG combined code
to manage this field...

For example if the field of view is an image I think thant into the "field" variable (launched with kint(field))
I could to found info to build html like:
-img src
-alt text
-height img
-width img
-title img

then I could override {{ output -}} to

<div>
<a href={{ link_to_href }}
<img src="{{scr_img }}" alt="{{ alt_img_text }}"/>
</a>
<div> Text example 1 </div>
<div> Text example 2 </div>
<div>

But nothing works beacause this info is not here in field or row variables!!!!

Where there infos are?
Correct is override views-view-field.html.twig?
How can getting this infos and how can access to it (I'm getting that the best practice is use "dot notation"
but what rules for it and what is the differece by protected and public infos showed by kint?)
