There is a brief article which shows how to utilize Helicon Focus in model railroad photography.
It is featured in the Nov. 2007 issue of the Model Railroader Magazine ( http://www.trains.com/mrr/default.aspx?c=i&id=2&iid=261 ). It is not available on-line (just in print). MRR's main page is http://www.trains.com/mrr/ .
The article is titled: Improve photographic depth of field, Using software to produce focused digital images
It is nice to see Helicon Focus in the spotlight again.
