Wow, look at this cool effect. You end up with these background images just barely coming through. I can show you a couple of the stages on this one. I didn't take photos in the very beginning.
This technique isn't my original idea. I found it a while ago on the internet. If anyone recognizes it, please tell me and I will give credit where credit is due.
The first coat is gesso. Keep your brush dry and drag it lightly over the images. Keep your strokes in one direction. Don't cover very much. Think about what you want to start to obscure and what you want to keep.
Follow it with more layers of different colours. Some you might want to glaze over the top - yellow gives an interesting effect. Others just lightly drag. It's fun to see how you can change the reading of the pictures by the placement of your strokes. Elements come forward and recede depending on where you cover and which colour you use.
Later I added packing tape transfers and writing. You can see how anything you add on top serves to make the background recede.
I don't know why the pages say "holy hope" or "over and above" or "get your". It was just words that came to me so I put them down. I think it's fun.
The only thing with this technique, it always seems to come up kinda spooky. I have done it on two spreads and both times the same. Nothing wrong with spooky. But I wonder if I could get a less spooky look, or if that is just what happens. See, over in the lower left corner, that was a rather twee photo of a doll, but spooky with this effect. Maybe I should try all really cutesy stuff and see what happens. That could be fun.
