blueprint effect?

I need some tips on creating a blueprint effect, as in architectural blue print plans. So far what I've done so far is this:

new image->new layer->fill with a light blue->clouds->little gaussian blur->new layer->fill with black->add alot of noise->change layer to color dodge->merge down->more guassian blur

which amounts to this:


which gives me a good start, but not the full effect I'm going for. I'm missing the random darker blue specks.

I'm not a real photoshop pro, just an amateur, so any ideas/help is appreciated.

Try adjusting the brightness/contrast (Image->Adjsut->Brightness/Contrast) Play around with the sliders, make it darker and darker until you get the effect you want. If you want to add blue, you can use the Color Balance (Ctrl+B) and change around the colors there.

Maybe this is not wath you are looking for but...

If have have acces to something like Autocad, save the file as an eps then open it in Photoshop...

I once use this at my job and it worked fine...
