Artistic collaboration
When there is visual affinity and a real exchange of value.
A collaboration can exist without monetary exchange, but never without value.
An artistic collaboration is an agreed exchange. Its value may be aesthetic, conceptual, creative, portfolio-based, reputational, communal, access-based or rooted in visual affinity.
An artistic collaboration is not open availability or a session without value. Intention, scope, credit, deliverables and image use must be agreed before production.
If an image will have promotional or commercial use, that use is discussed beforehand: where it will appear, for what purpose, for how long and with what credit.
When there is visual affinity and a real exchange of value.
Portrait, portfolio, book or personal editorial work.
Brand, product, campaign or business communication.
