Tips and Tricks

Squaring up technical photos of paintings

Taking a square-up photo of a painting can be challenging due to several factors. First, the camera must be precisely aligned with the painting to avoid distortion and ensure that all angles are square. This alignment requires careful positioning of both the camera and the artwork, often involving the use of tripods, spirit levels, and measuring tools. Overall, taking a square-up photo of a painting requires patience, precision, and a methodical approach to achieve a high-quality, accurate representation of the artwork. When you are back in the studio and you realize your images are not straight, yes, there are methods to square up a set of images, which involve correcting the perspective and alignment of photographs to make them appear square and straight. This process is important for ensuring the accuracy and consistency of images, particularly for artworks, architectural photographs, or any other subject where precise geometry is desired. This video shows how to square up technical photos using GIMP.

Panoramic Technical Photography Documentation for Large Paintings

Technical photography documentation of large paintings can be effectively achieved using the panoramic method. For straightforward techniques like visible and raking light photography, the process is relatively simple. However, methods such as Ultraviolet Fluorescence and Infrared Fluorescence require special attention due to the necessity for long exposure times. Careful planning and execution are essential to ensure high-quality results in these more complex imaging techniques.


CHSOS: Our Journey in Advancing Technical Art Examination Equipment

This video showcases our equipment from the early days of CHSOS. Back then, we didn’t have a proper Pigments Checker or a set of Technical Photography filters with magnetic adapters. We’ve come a long way in making technical art examination easier with the Technical Photography KIT 🙂
