Helicon Focus and depth-of-field

Today I tried out the famous Helicon Focus software. It's a great tool that takes several images with different focal points and combine them in a single image with a great depth of field.
It's a very helpful tool in model railroad photos, since we can't have enough depth of field when taking close up photos, even with good cameras. Here is my first attempt with the software:

And this is just one of the several images given to Helicon Focus; notice how the background and foreground details are out of focus, compared to the processed image above - this image has the leading engine nose as a focal point.

Helicon Focus is a bit pricey, but it's very easy to use.
