Judging by many photographs especially of old WW1 battleships slipping over the horizon black smoke bellowing out makes a great diorama doesn't it ?
Because a diorama is very much a stationary object, a 3-D photo if you like where you'll view all sides. How much smoke do you attach to a scale model ? Taste I don't feel quite cuts the mustard here, and while you can actually buy black/red cotton smoke effect in a pack, you'll also be able to buy smoke which is basically soot and suppose to look like smoke.
Some people on the site can and some such as myself can't - superimpose a photo upon the model showing smoke on a photo of the model rather then sheer a sheep and completely hide the subject.
The problem with using cotton wool is in the fiber, you can only scale so much before it simply looks like cotton stuck on a plastic model, as I have said ''moaned'' many times before, there is a HUGE market for someone to pick up out there, today people are no longer happy just building their model, they want all the whistles and bells to go with it, and those people have now taken this hobby to the next level - diorama - which screams out for after-market products, and where are they ? Very few and far between.
