They might, however, have an interest in how the scratchbuilt side sills were constructed, enabling those techniques to be used on projects such as build- ing a flatcar. Both Above: These two identical photos illustrate the relation between aperture and depth of field. The top photo was taken at f5 while the photo and the lower image was captured at f32, showing the deeper depth of field. The trade off is longer exposure needed to properly expose the image.

For example, while one may not have any interest in that particular boxcar, learning how two cars were spliced together to create it may provide something that can be used in other endeavors.
