The image presents two photographs of an engraving on a marble tombstone. In the first photograph, the engraving is not visible due to dirt and lichen accumulation. The second photograph was taken after exposure to ultraviolet (UV-A) light.

**Photograph 1**

* **Background:** The background features the top portion of a rounded archway.
* **Engraving:** An indistinct hand grasps an open book, which is partially obscured by dirt and lichen. The text "Fanny" is visible on the cover.
* **Color:** The overall tone is grayish-brown.

**Photograph 2**

* **Background:** A black background with a white UV-A light source at the top of the image.
* **Engraving:** After exposure to UV-A light, the engraving becomes more visible. The hand grasping an open book is now discernible, although the text "Fanny" remains partially obscured.
* **Color:** The overall tone is grayish-brown with a purple tint.

**Summary**

The image illustrates the effect of UV-A illumination on an engraving on a marble tombstone. While regular light exposure does not reveal the details, UV-A illumination makes them more visible by causing lichen to fluoresce and removing dirt buildup. – AI vision
