Revision History 2020
This is the 2020 revision history of the Lumen Perfectus Web site. Probably not of general interest,
but it helps us keep track of the site's growth and maintenance.
We replace the "Photo of the Day" daily; we won't log those changes here.
Use the "newest photos" link in the table of contents at left to go directly to our
most recent additions.

Our first article of the year, “Kind of Blue,” discusses how shadow areas in photos of snow
and ice, especially in pictures made under sunny skies, often have a very blue color cast and why I prefer
to mitigate this 'flaw' in our cameras.
-
25 January: This week's addition is a photo from October, 2018, of fall color and towering rock above the
Clark Fork River near Garnet, Montana.
-
18 January: In keeping with the current season and weather, we've added a photo of heavy rime on the branches
and needles of a Ponderosa pine tree. Adding this 2015 picture required shuffling some of those in our Ice gallery
and removing a sub-par photo.
-
11 January: Adding a 2017 photo of Cannon Beach (OR) required shuffling most of the images in our Oregon Coast
gallery. We also added a list of our three Oregon coast articles to each of the gallery pages.
-
04 January: Our first photo addition of the year is a 'high key' picture of a trumpeter swan and bright sky
reflecting in a small local lake. The photo was made last spring when a pair of swans frequented the lake.
