Way back when I got my very first version of Photoshop, I think it was Limited edition 6.0 and was probably in 1997-98.
I had great fun playing with the filters in those days. I took a photo of a zebra at the Franklin Park Zoo in Boston (I have it somewhere and will post it I can find it) I remember glowing edges and solarize and neon glow and invert.
I remember that there were 4 altered versions, and I printed them in the same page, framed them and gave them to my daughter for Christmas one year
I found the original zebra and another of the altered versions!
