How can I etch a photograph of people into either plexiglass (or lucite, lexan, acrylic, etc) or regular glass?
But without using a laser etching machine? I've seen chemical etching into brass using chemicals that produces a detailed effect, but I want that on a see-through surface. I'm not good at free-hand painting, so using Armour Etch without a stencil/mask is essentially out of the question.
Also, would Armour Etch work on plexiglass, even though it is a different material than regular glass (SiO2)?
