# Track photographs with Piel Viva

> Document tattoo-session photographs across checkpoints, annotate regions and write artist observations without medical claims.

Piel Viva helps you document **visible differences** between real photos associated with one tattoo session. It is a photographic record and comparison tool, not a medical assessment.

## Timeline and checkpoints

The **Evolución** view supports the initial reference and session moments, together with follow-up checkpoints **D3, D7, D14, D30, and D90**. Missing photographs stay pending; LIMINAL does not fill them with simulated real results.

**1. Choose the session**

Open Piel Viva and select the correct session in the header.

**2. Set an initial skin reference**

In **Referencia de piel**, upload a photo before the stencil when appropriate. Select and confirm a representative region.

**3. Upload checkpoint photographs**

Under **Evolución**, choose the relevant checkpoint and select **Añadir foto**. Supported files are **JPG, PNG, or WebP**, up to **15 MB**.

**4. Mark an area**

On a checkpoint with an image, select **Marcar zona** and choose the relevant area. Use **Zonas** to adjust its label, note, and boundaries.

**5. Write your observations**

In **Notas**, select the checkpoint, describe what you see and what you decide, and select **Guardar nota**.

## Capture tips

Use consistent framing, soft light, a similar viewing angle, and unfiltered photographs whenever possible. If captures are too different, record the limitation rather than forcing a comparison.

> [!WARNING]
>
> Piel Viva does not diagnose infection, illness, healing state, inflammation, hydration, or pigment retention percentages. Medical questions require a qualified healthcare professional.
