Show HN: An open source R package to add depth of field to images

Author here! This is part of a series where I describe the development of an R package I&#x27;ve been developing for mapping and visualization:<p>Show HN: A raytracer to shade, plot, and 3D print topographic maps in R, part 4 <a href="http:&#x2F;&#x2F;www.tylermw.com&#x2F;3d-printing-rayshader&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.tylermw.com&#x2F;3d-printing-rayshader&#x2F;</a><p>Show HN: A raytracer to shade and visualize topographic maps in R, part 3 <a href="http:&#x2F;&#x2F;www.tylermw.com&#x2F;3d-maps-with-rayshader&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.tylermw.com&#x2F;3d-maps-with-rayshader&#x2F;</a><p>Show HN: A raytracer to shade topographic maps in R, Part 2 <a href="http:&#x2F;&#x2F;www.tylermw.com&#x2F;making-beautiful-maps&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.tylermw.com&#x2F;making-beautiful-maps&#x2F;</a><p>Show HN: A raytracer to shade topographic maps in R <a href="http:&#x2F;&#x2F;tylermw.com&#x2F;throwing-shade&#x2F;" rel="nofollow">http:&#x2F;&#x2F;tylermw.com&#x2F;throwing-shade&#x2F;</a>

This is impressive, and I hope you&#x27;ll forgive my rather pedantic comment, but it seems to me you&#x27;ve got the terminology the wrong way around. What you&#x27;ve got here is a process for <i>reducing</i> depth of field, not adding it. In the rendered examples which are labeled on the left, &quot;No depth of field&quot;, I&#x27;d call that: &quot;Infinite depth of field&quot;.<p>Though of course looking at the pictures makes the intended meaning clear in any case.
