Introduction This is a guide to teach you how to do photographic documentation for artefacts of the Catholic Church in Hong Kong. It covers the whole workflow from the preparation of equipment to the inventory of the photographs. You shall follow the following workflow: Set the Prepare the Take environment equipment photographs up Photoshop Create 360° Publish your the photos images 360° image Inventory the photogrpahs and images Figure 1.1 Workflow for photographic documentation of artefacts. 3 Artefact Photographic Documentation Guide 2. Types of photographic documentation There are 2 types of photography required for the documentation of artefacts. 2.1. Basic documentation All artefacts inventoried shall be accompanied with a basic photographic documentation set of 3 photos: one from the front, one from the side, and one from the top (Figure 2.1). If the back or the opposite side are very distinctive, they might also require an extra shot. If there are special details on the artefact, e.g. an inscription, a relief of the Saints, or major traces of damage, they should also receive extra close-up shots. Figure 2.1 Basic photographic documentation (created by the study). Figure 2.2 Close-up shot to show the inscriptions on the artefact. 4 Artefact Photographic Documentation Guide 2.2. 360° rotational images Apart from normal photographs, 360° rotating images might also be required for documentation and exhibition. The range of church artefacts which might require a 360° rotating image is broad. There are thus 2 approaches you may choose to make 360° rotating images. Figure 2.3 360° rotating object photograph. (https://www.pressrelease.com/files/3e/03/e22e7518f4df09a3c35b3a92081c.jpg) 2.2.1. Turntable 360° – Small Movable Objects For movable artefacts with width and length smaller than 18cm, you should adopt the Turntable 360° approach (Figure 2.2). All you will need to do is to put the artefact on an automatic turntable and take photographs at regular time intervals. Figure 2.4 Turntable 360 approacch (created by the study). 2.2.2. Compass 360° – Large Movable Objects or Immovable Objects For movable artefacts with width or length exceeding 18cm, you should adopt the Compass 360° approach (Figure 2.3). This is a bit more complicated, requiring you to mark a compass or part of a compass on the ground to determine the angular intervals before taking the photographs. Figure 2.5 Compass 360° approach (created by the study). 5 Artefact Photographic Documentation Guide 3. Equipment and Software As there are 2 approaches for taking 360° rotating object photographs, there are also 2 sets of equipment required correspondingly, as well as some common equipment. 3.1. General Equipment Equipment required for both approaches are as follows: • Computer with at least the following configuration: o Windows (Windows 7 (SP1) or later): Intel® Core 2 or AMD Athlon® 64 processor; 2 GHz or faster processor, ≥2 GB of RAM, 2.6 GB or more of available hard-disk space, 1024 x 768 display, OpenGL 2.0-capable system. o macOS: Multicore Intel processor with 64-bit support, 2 GB or more of RAM, 4 GB or more of available hard-disk space, 1024 x 768 display, OpenGL 2.0- capable system. • Digital camera with the following functionalities: o Manual mode which allows you to fix an aperture, shutter speed and ISO value combination throughout all photographs in a set. o (Preferred) Interval shooting mode which allows you to take pictures at regular interval. o A photograph resolution of at least 5 megapixels. o A lens with a 35mm equivalent focal length of 50mm or above
