Revision History 2021
This is the 2021 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.
(2021)
- 04 December: A sky of dark storm clouds at sunset resulted in a series of dramatic sky images, today's posting being the last of those.
- 29 November: A frustrating attempt to capture snowberry in snow using a long lens and focus stacking for increased depth of field led to this month's article, “Maintaining Focus.”
- 27 November: Today's new photo is a focus-stack made from four images of snowberry on a sunny November morning. The focus stack was needed because the images were made with a 400mm lens just a couple of feet from the subject, limiting depth of field to fractions of an inch.
- 20 November: Clouds thickened in a stormy sky at sunrise, eliminating the chance of nice color over the Mission Mountains, in a photo made in early October near Montana's National Bison Range.
- 06 November: We've added another in our series of 'minimalist' photos, of an after-sunset sky above a ridge west of Montana's Flathead Lake.
- 30 October: To our Abstract and Graphic gallery we've added a photo of mowing patterns in a hillside hay field, photographed in soft morning sunlight.
- 29 October: Our October article, “Berry Beary,” is a fun story about watching a black bear tear up a chokecherry patch close enough to our house to get some nice photos.
- 23 October: In this week's new photo, sunset lights the hills above western Montana's Flathead Lake, with the Mission Range in the background.
- 16 October: During last week's session photographing after sunset (see our previous entry below) we got a photo of a deer on the ridge seeming to watch the amazing sky.
- 09 October: A sky of dark storm clouds at sunset resulted in a series of dramatic sky images, today's posting being one of those.
- 02 October: We've added the first in what may become a series of 'minimalist' photos, this one of a pair of small trees on a distant ridge, with a single small cloud in a hazy sky.
- 30 Sepember: This month's article, “A Whole Lotta Nothin',” starts with the story of Murray Fredericks's 'minimal' photos of Australia's Lake Eyre, and how those images inspired an attempt to make my own variety of minimal pictures.
- 25 September: This week's addition is a photo made in May, 2018, across Lake McDonald in Glacier National park.

- 04 September: We've added another photo of the black bear that visited our property last month.
- 31 August: This month's article, “White in Black and White,” explains how a friend's compliment on one of my pictures led to a 'project' photographing wildflowers and processing them into B&W pictures.
- 29 August: A black bear (Ursus americanus) has recently been visiting our property and feasting on berries in a chokecherry thicket (and destroying the bushes). We've been able to get a few photos, and the first one is posted today.
- 14 August: We added a photo from the winter of 2019 of Canada geese (Branta canadensis) on a mostly frozen Flathead Lake. We moved some photos in the 'Other Birds' gallery to accommodate this addition in the correct chronological order.

- 25 July: We've posted another photo, likely the last for this year, in our black-and-white series of flower images. This required adding a seventh page to our 'Close-up Flowers' gallery.
- 17 July: Yet another in our series of B&W images of white flowers, today we added a newly-processed picture of trillium (Trillium grandiflorum), the picture originally captured in May of 2020.

- 07 May: After nearly a decade of service, our Epson Stylus Pro 7900 printer has reached the end of its life. Removed all 'Purchase a Print' links, removed the link to our photographic services page, and updated our 'About' page's section about offering prints for sale.

- 28 February: This month's article, “Batsh*t Crazy,” is an off-topic rant about the Wingnut faction and its refusal to do the common-sense things to help protect themselves and others from COVID-19. Next month I'll get back to the usual photographic topic.
- 27 February: A red fox visited our property two days ago, and posed for a few photos. Today we've posted one of those.

- 16 January: added, to our Ice and Snow gallery, a photo from 2010 of rimed trees and fog in distant hills. Rearranged pictures on that gallery's pages 7, 8, and 9 so the older photo could be inserted in the proper chronological order (on page 7).
- 09 January: In late December we made an attempt to photograph the convergence of Jupiter and Saturn. Thanks to a cloudy sky on the 'best' evenings, we made the photo posted today three evenings after the prime date. We added a second page to our 'Night Sky' gallery to accommodate this addition.
