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.
(2020)
- 28 September: Our September article, “Making Weather Personal,” tells the story of my installation of a new personal weather station, the WeatherFlow Tempest.
- 26 September: Added a wintry picture from 2008, of ice on northeast Ohio's Chagrin River.
- 19 September: On a smoke-filled white-sky morning a sharp-shinned hawk paid a visit, perching for a few minutes in a gnarly Ponderosa pine. The bird appeared almost exactly one year after a seemingly identical hawk came through. Could it be the same bird? The new photo has been added to the Birds gallery next to last year's version.
- 12 September: A March, 2019 photo of Canada geese about to land in an icy Flathead Lake is this week's addition. Adding this older image required reordering pictures on pages five and six of the 'Other Birds' gallery.
- 29 August: We've added another photo of comet NEOWISE, the picture made about 11:15 pm on 18 July. This is the last of our NEOWISE photos. No, really.
- 28 August: Our new article, “Comet Comity,” describes the fun we had trying to capture images of comet NEOWISE in July.
- 22 August: Digging into the archives we've added a May, 2019 photo of a female mallard (Anas platyrhynchos) perched on a branch over a small local lake. To accommodate the older photo we shuffled some pictures in our Birds gallery.
- 15 August: We've added another photo of comet Neowise, the picture made about 4:00 AM just after moonrise.
- 08 August: We've added Yet Another photo from the rapeseed fields (see recent entries below).
- 01 August: Back to adding photos of the rapeseed fields (see 4, 12, and 19 July entries). Today we've added another, this one a 'focus stack' of seven images for maximum depth-of-field.
- 31 July: Our July article, “Stacking the Deck,” describes how we used a technique called 'focus stacking' to capture images of blooming rapeseed (canola) fields.
- 25 July: while we still have a few more photos of the canola fields (see the last three weeks' entries) to add, comet Neowise visited the night sky this month, and we got one good photo (from many attempts), which is our addition this week. Back to canola photos next week (probably).
- 19 July: 'Yet another' photo of a rapeseed field, this one with western Montana's Mission Mountains as a backdrop on a hazy July day.
- 12 July: We've added another photo of the rapeseed (Brassica napus), or canola, fields with their brilliant yellow blossoms. Western Montana's Jette Lookout is in the background.
- 4 July: Huge fields of rapeseed (Brassica napus), or canola, have been in brilliant yellow bloom in recent days. Today we added a photo of a rapeseed field under a blue Montana sky. The photo is one of a series we'll be posting over the next few weeks. We added a page to our 'Hand of Man' gallery for these images.
- 28 June: Massive fields of canola are at peak bloom, and bees are everywhere. Today's addition is a photo of a honey bee on a canola blossom on a brilliant sunny morning.
- 25 June: This month's article, “Staying Home,” offers some thoughts on staying home during a pandemic but still getting out to make photographs.
- 20 June: Today's picture is from an April session photographing a crumbling fence after a late-season snow.
- 13 June: This week's addition is another photo of a junco, from a group of bird pictures made after an early April snow storm.
- 06 June: We've added another 'creative blur' photo, again of the trillium blossoms we photographed for our 16 May posting. This time it's a radial blur with a stutter-stop zoom from short to long focal lengths.
- 30 May: This week's new photo is of the May, 2020, full 'supermoon' rising over frosty pine trees, as described in the article posted yesterday (see below).
- 29 May: Our May article, “Moon Over Montana,” describes photographing the April and May full 'supermoons.'
- 23 May: It's a busy time of year around our bird feeders, lots of interesting visitors passing through on their way to wherever they'll spend the summer. Today's addition is a picture of a white-crowned sparrow (Zonotrichia leucophrys) in morning sunlight.
- 16 May: We've added a 'creative blur' photo. Rotating the camera during a long exposure of a trillium blossom created an interesting geometrical pattern.
- 09 May: This week's photo was made as the rising sun lit trees on a distant ridge as the full April 'supermoon' set beyond it.
- 02 May: Yet another photo of the old fence (see the 18 and 25 April entries), this one with a meadowlark adding a bit of color to an otherwise drab scene.
-
27 April: This month's article tells the story of photographing a decaying wood fence during the 'stay home'
order prompted by the COVID-19 pandemic. The pictures were made from a normally busy highway that's now
traffic-free, making for a strange experience.
We've moved the article's slide-show Javascript and the associated CSS to our 'code' directory. - 25 April: We've added another photo of the crumbling wooden fence (same subject as last week's addition).
- 18 April: Added a photo of a decaying wood fence in the snow. This required added a new 'gallery' page to the site.
- 11 April: clear skies during the recent (7 April) full supermoon presented a photo opportunity; we got a couple of keepers from that early-morning outing. Today's posting is one of those.
- 04 April: We've had an irruption of dark-eyed juncos here, along with an early April snow storm. Today's photo addition is, not surprisingly, a close-up view of a junco in the snow.
- 28 March: We've added a landscape (above ground this time!) of rising sun lighting grassland in Wind Cave National Park.
- 27 March: Our March article, "Photos for Furniture," tells the story of an interesting photo project, making prints to apply to the sliding barn doors of an entertainment system cabinet. We dabble with prints on canvas, metal, and acrylic panel.
- 21 March: This week's addition is another photo from Wind Cave National Park. This is an 'artistic blur' made inside Wind Cave.
- 15 March: We've replaced a photo in the Abstract gallery with a picture made inside Wind Cave (in Wind Cave National Park, South Dakota, U.S.) during a 2010 tour of the cave.
- 07 March: A recent shower of graupel left the pellets quite distinct on top of hard-pack snow. Afternoon sun lit the pellets making for nice light/shadow contrast. This week's addition is a long-lens photo of that, a bit of an experiment to see if the sparkle of the scene could be captured.
- 29 February: On this Leap Day we've added a photo of a small section of McDonald Falls in Glacier National Park.
- 25 February: This month's article, “The Silence of The Fans,” describes going to extremes to silence a loud fan in our Oyen Mobius 2C external drive box.
- 22 February: We've added a photo of a winter storm sunset, made from our home in west-central Montana.
- 15 February: This week we added a photo of a foggy sunrise from a 2014 trip to Beard's Hollow on the Washington coast.
- 02 February: In March last year we discovered a small ice cave on the shore of Glacier National Park's Lake McDonald. Today's addition is a close-up photo of the textured ice on the floor of that cave.
- 26 January: 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.
- 01 January 2020: Updated the Revision History and Home pages for the new year.
