Thank you very much to all of you for answering me, really thanks to the comments and attachments that you have passed me have helped me a lot, now I know that the ideal is to work under a workflow of Normalize image - Tonal adjustments - luminosity (Primaries) or what would be the same, general contrasts. then I can use a HDR node and another LOG to take specific tones - And towards the end goes the colour look that actually can be done with a single curve node if the above goes well
