AVRs AND PHOTOMONTAGES
Accurate Visual Representations (AVRs)
Accurate Visual Representations / Verified Views are the most accurate form of photomontage. They offer confidence to the client, planning authority and consultees that the visualisation is accurate to location and scale within an existing photograph and if required all of the data can be passed to a 3rd party to verify the accuracy.
In order to class a photomontage as an AVR the following steps are taken:
-
Accurate 3d Model - Supplied by the architects or created by Snapshot Visuals;
-
On-Site Photography. This is carried out in-house by Snapshot Visuals and conforms to all current guidance;
-
On-Site Survey - Snapshot Visuals are able to conduct an on-site 3d survey using equipment with an accuracy of +/-2cm. We are able to conduct the survey at the same time as the photography saving time and money for our clients;
-
Visualisation - Our in house team of skilled visualisers combine all of the information above to create a real-world 3d model using the survey to align the model to the existing features in the view, creating a virtual camera in our industry recognised software to mimic the camera used in the existing photography. This is then rendered out at the level of detail required by our clients.
Snapshot Visuals carry out all AVR and Photomontage work to the guidance required by the Local Authority, including:
-
Landscape Institute TGN 06/19 Visual Representation of development proposals
-
-
London View Management Framework Supplementary Planning Guidance (March 2012)
-
-
Scottish Natural Heritage (SNH) Visual Representation of Wind Farms
-
-
The Highland Council Visualisation Standards for Wind Energy Developments
London View Management AVRs
Levels of Detail
The London Management View Framework Supplementary Planning Guidance (March 2012) separates AVR production into 4 types, ranging from AVR Level 0 to AVR Level 4:
-
Level 0 - Location and Size of Proposal;
-
Level 1 - Location, size and degree of visibility of proposal;
-
Level 2 - As level 1 + description of architectural form;
-
Level 3 - As level 2 + use of materials
LMVF AVRs are produced as single frame images using either a 50mm or 24mm lens on a full frame dslr camera.
Snapshot Visuals can produce AVRs to any of the levels required.
In addition Snapshot Visuals can produce cumulative AVRs showing how your development will sit within any other local development proposals.

Photomontages
Levels of Accuracy and Panoramic Detail
The Landscape Institute TGN 06/19 Visual Representation of Development Proposals categorise 4 types of Visual Representations:
-
Type 1 - Annotated Viewpoint Photography;
-
Type 2 - 3d Wireline / Model;
-
Type 3 - Photomontage / Photowire;
-
Type 4 - Photomontage / Photowire (survey / scale verifiable)
The main difference between a Type 3 and Type 4 representation is that a Type 3 photomontage is aligned using only desk-based assessment tools including Google Earth, site topographical surveys and OS Maps.
A Type 4 photomontage is site-surveyed to give the most accuracy and is the most akin to a London Management View AVR.
The LI guidance also gives the flexibility to produce panoramic visualisations.
