The work can be divided into two different operational criteria:

• The physical approach with the support of a paper sheet, where we both act on the same work simultaneously.
• The digital approach where, using personal iPads, we exchange interventions by taking turns.

The image formation process, which is the formal hallmark of working with four hands, blends seamlessly with digital tools.

The layering in digital painting is procedural; the image becomes substance in the temporal unfolding of creative development. The creative process reaches inertia when a kind of balance in reciprocal interventions is recognized.

Placing it in a delimited context, perceiving visual stimuli, the spatial condition within a linear temporal development, revives input from perceptual memory through shapes and tones that, thanks to the possibilities of the technical means of the digital tool, can more easily establish a direct connection with internal mnemonic processes.

The development of the work is, for the reasons already mentioned, to be understood as a union of separate moments that find unity in the support.
