OK I promised Pictures:
First here is what I am talking about and contrast between the actual poster and the watercolors...
So I went to town fixed my airbrush; built an easel because you can't paint down...
First to try black on an older poster. The matte finish isn't an issue here. The black does come out darker though.
Before airbrush:
After Airbrush: (there was some overspray cause I was careful but not too careful - just testing things out)
Regular water color leaving a matte finish:
Added Gum Arabic to the mix:
Point Break All Finish Up....
Now to the Lost Boys. Remember all the matte finish issues. The airbrush and a little Gum Arabic eliminated this concern.
Remember the head. This was a huge issue with a dark line running across. I am no expert at the airbrush but I figured if I could make a base color opaque to eliminate the line I could come back aver and get it close. Also notice the stain in the orange flame area. This didn't come off in washing...
Here is the base coat of white.
Then a darker coat of the yellow.
A final darker coat and a few sprits of black to take it back...
Now to the stain. We saturated the stain with a lighter yellow and let dry.
Then came back with the main color.
Finished!
Man I was ready to give up yesterday... The restoration and color matching stuff is the meat of the art. As Rich and Bruce (and others) said slapping a poster on linen is something that can be done all day...
