Hi Greg well when we start MRS I have decided to paint some backdrops
at a time I used Rough drawing techniques (for advertising and modeling)
it's alcohol pencils from Pantone or Copic on a special paper which is very fine !
My inspiration came from Morning sun books especially the trackside (Toledo Cleveland Chicago Detroit etc) just excellent books, I chose some pictures that I try to redraw with some modifications to fit with our layout , when the drawing is finish I just cut it following the top of buildings and all the scenery.
On the backdrop that have been painted with light sky blue I just add a fine white coat with an airbrush at the base for the "hazy" also on the top of my drawing then I glue it using spray glue from 3M (you can use repositioning one, it's better if you make an error)



On the last pic it's interesting because some Pylone are real and the second on the background just a drawing, wires come by little holes on the background and have been redrawn on the background for continuation, this have been done before fixing industries /buildings, Grass trees have been drawn too and real one (I mean from woodland and others) glued to make transition, so you have this effect of "profondeur"
it's a french term that mean something like deepness, sorry I'm not sure if it's correct in english !
Well I know that some people think and will tell me "I don"t know how to draw"
nevermind and here's come technology with Internet and some software like Photoshop
Finally now I make some research and I found around the web beautiful pictures for examples from UIC on Flirck, I found one for my two new modules to fit in the back of the street, loading on photoshop I just put some filter on to transform it, like a drawing
This step is important because a photography is too much detailed, in reality backdrop must be a bit blurred like paintings, so this kind of filter in photoshop are really good!
after I use the same technics to put in place
Hope I'm clear in my explanations
