Puzzle Description:

Selenium, element number 34 in the periodic table, has many uses. This nonmetal was discovered by Jons J. Berzelius in Sweden. Selenium responds to the intensity of light, which is why it is found in devices such as electric eyes, photo cells, and light meters for cameras and copiers. (Hense, the image of the camera relates to Selenium's response to the intensity of light).

i got all but the middle part solved via line/edge logic
maybe i wasnt patient enough but i think i had to guess on the middle
nice camera

Thank you-I think I might have to revise it a bit to make the middle easier to solve using logic!

New version published by MCough.

it looks very nice; good job

whoops, double entry

Also used in dandruff shampoo, which can be used in a pinch to kill silicon-based life forms! (According to the movie Evolution)

Had to guess the middle and still don't quite have it.

I came back to this puzzle and was able to finish it. Still some guessing to get started. A really great image.

Finished without guessing, but it was tough.
