Has anyone done Ortho-litho effect in On1. No grays, just black and white. If so, how did you do it?

  I don't know what Ortho-litho is, but based on your description I turned the top image into the bottom one. Does that count?

  If so, I can post instructions.

  Ortho was a type of extremely high contrast film used to photo copy books and documents, lithography. Pure black, pure white, no grays. I did some special effects stuff in the darkroom with it back in the day. I also reproduced some of them in Photo RAW.

  Daniel, let me find the photo and I'll post again after refreshing my memory.

  This is what I came up with. It shows the steps I took. All except the first one. :(

  

  I started with a shot of a single aircraft against the sky so I had a simple subject to work with. This is the part I do not remember. Somehow I got it to be a silhouette, probably with masking and a couple of extreme Curves - one for the background to go all white by pulling up the Black point, the other for the aircraft by going the other way and pulling down the white point.

  

  I duplicated that Layer and Inverted it with another Curves Effect by reversing the Black and White points. The Transform tool was used to size it down just a bit and reposition it to fit inside the silhouette to create the outline. Then I duplicated and Transformed the outline several times for the final effect.

  On that first step to create the silhouette -

  I duplicated the entire photo so I could work with the sky and aircraft separately. That is where I used the Curves - one on each of them to turn them pure white and pure black and a mask to combine them. I Flattened that into that first Layer called 'positive'. That's why the steps I used are gone. :)

  Thanks for the comments. Brian's is the effect that I was looking for; thanks for the help with that. I would also be interested in how you did the water lily Rick.

  Sure, it's not difficult...

  Open the image and use any method to make it B/W. In this case, I simply took down the saturation and vibrance.

  

  Then duplicate the layer...

  

  With the top layer selected, set the blending mode to difference...

  

  Lastly, select Transform...

  

  and slightly move the layer in whichever direction creates the best effect...

  

  After that, you can merge the layers and continue working as a normal image.
