Abstract

Technical Photography (TP) is a non-invasive technique used for analyzing an artwork to decide the conservation method, pigment classification, hidden detail revealing, and painting retouching. This technique requires a modified digital camera that removes a visible-pass filter to acquiring a set of broadband spectral image. The problem with this technique is that it takes time during the image acquiring process due to several combinations of light source and filter in order to collect all information in the painting. Our research aimed to develop a system that can reduce time in the image acquiring process by using one digital camera and one modified digital camera to acquired two images in different spectral bands simultaneously. All acquired images are processed with image processing software. Full-frame DSLR (Nikon D850, 45.7 megapixels) and a mirrorless (Nikon J5, 20.8 megapixels) camera are compared in the topic of image register, image quality and the performance were analyzed in order to choose the suitable image acquiring system and create comparison table. This system is an alternative way to reduce time and process in the image acquiring process in technical photography technique.
