The LI Technical Committee published the long-awaited refresh of Photography and Photomontage guidance (01/11) on 17 September 2019

Following an extensive process, the LI Technical Committee has published Technical Guidance Note (TGN) 06/19: Visual Representation of development proposals – the long-awaited refresh of our Photography and Photomontage guidance (01/11).

Though the change in title reflects the emergence of different technologies, the focus of the guidance remains on the core photography-based methods used by most practitioners. (Detailed guidance on some emergent technologies may be the subject of a future workstream.)

The publication of the TGN follows extensive consultation with LI members and technical experts in photography, photomontage and landscape and visual impact assessment.

Your work: Adopting and adapting to the new guidance

The LI’s view is that TGN 06/19 should apply to new commissions from this point on, but that a reasonable grace period will apply. We expect that practitioners will make reasonable judgements over implications of the changeover.
