With only few days to go before finalizing our project, it became more than clear that the biggest mistakes were made at the very beginning of the project. That being said, we did the best as we thought we could during data capturing session at the National Science Museum in Maynooth.
Before capturing each object we took couple of trial photos, to make sure that the camera settings are right, focus is correct and that the object is placed correctly within the light box (it was also important to determine which background would look better: black or white). Our objects had many brass, glass and polished wood elements which made it very challenging to make sure that there is as little reflectiveness as possible (post factum, we concluded that it would be best to use polarizing filters). Some of the objects had movable parts that would be set in motion as the objects were rotated during capturing, which caused some additional issues with focus. Each taken image was being examined on the camera display, however it was impossible to spot all the flaws on such a small screen.
For this reason, I’ve decided to bring my laptop on the site and use it to check the quality of the photos in case we needed to re-take the whole photo shoot. It quickly became obvious that the colour and brightness of images varied from camera display to laptop. Also, it was much easier to see which images were too blurry to be used in processing. In the case of one object, the whole capturing had to be re-done due to bad lighting and cropped images. Since we had access to Agisoft, we decided to check if the quality of the photos will be sufficient for the software, which was crucial for future processing. Majority of them turned out to be over 0.5 which meant that can be successfully processed. However, knowing the struggles we were to face in the future, I regret not attempting to align photos for each object while we were at the museum – it would probably help us in taking better quality photos i.e. pay greater attention to 60% overlap of the image, especially during taking photos at different angles.
