Looking at an article on the Blackburn Skua in a magazine. It is accompanied by a side view about six inches long (150mm). It reproduces every rivet and quite a lot of grime enhanced panel lines. The effect is striking. But if you look at the accompanying photos, which are good quality official pictures, the rivets and most panel lines are barely visible. No grime as far as I can see but some weathering. Profile artists, like modellers, can go a little overboard when it comes at such things. Surface detail should be in proportion to the scale of the image. Ask the question, will the image be big enough that if it was the real plane I would clearly see every rivet? There are some images on this site for which the answer is most definitely yes but for most the answer is no.
