Now that the roof is mostly finished ,it is time to break out the weathering materials,the acrylics and pastels.
I washed on very thin coats of raw umber over all the previously
painted nimbus grey wood areas.I then took out my trusty toothbrush and
flicked raw umber spots on the black as well as the white checkerboard
pattern.You can add a little of the nimbus grey to the mix if you want
the weathering of black areas to be more visable.
I then took some
medium grey pastels and shaded the areas between the battens and the
sandpaper roof.If you make a mistake and lighten an area too much
remember you can always go back over the area with black pastels again
to darken the area if need be.Experiment with different shades of grey
with black to get a nice blended-shaded transition.
Each nail(or
pin) is then given a dot of burnt umber gesso followed by a coat of
burnt sienna.I used to paint around each nail hole with watery burnt
sienna but I find a better method is to take a small brush and a tiny
amount of burnt sienna pastels and shade the wood around the nail holes
so that they look rusty.You can even have some of the rust run down
onto the black and white roof for greater effect.It is really
worthwhile working to weather the roof properly as this is a very
noticable part of the diorama besides its lots of fun and very
rewarding to look at when finished.Cheers! John.
It has been said that the difference between a "pilot" and an "aviator"
is that a pilot is a technician,and an aviator is an artist in love
with flight.
