The digitization process is a multi-faceted approach that takes into consideration the unique characteristics of each specimen to acquire highly accurate and precise models. This process helps to reduce the level of artistic bias while working with each model.

Both photogrammetry and laser scanning methods generates a “point cloud” based on the position of the specimen relative to the cameras.
Photogrammetry methods generates a “point cloud” based on the position of the specimen relative to the camera and allows for the capability to capture fine detail that approaches the realm of microscopy in some instances. To fully capture a specimen in high detail 40+ images and a 360° degree rotation of the specimen is required  in order to create a mesh.  
Photogrammetry allows for the capability to capture fine detail through the use of macro lens and creates 3D models in detail that approaches the realm of microscopy in some instances. To fully capture a specimen in high detail 40+ images and a 360° degree rotation of the specimen is required  in order to create a mesh.  


3D imaging of biocollections in the scientific community has largely been associated with expensive microCT Scans (digimorph.org) which is created by slicing an object based on material density  measured by X-ray transmissions.  Although this can provide scientists with important measureable information about structure and morphologies they do not retain color and external texturing which is needed in taxonomy and specie identification.
