Engraving the plates

I received back the light box from the framer yesterday, I was pleased that my idea worked and also that it looked striking. I had included three layers of plates, the same image engraved onto perspex lit from behind, and decided that another two layers would create even more depth and a stronger image. So, I made two more engravings and now it's back with the framer. Initially had I engraved three plates of the same T-cell, each plate showing different attributes of the same cell. This was an accurate depiction of the research, but proved to be visually too confusing, so engraving the same image, but repeated, was the solution. I am conscious of the fine line between illustrating a scientist's research and creating something which is also more universal and exists in its own right... I'm still exploring that.
