OpenCourseWare All Grown Up: Hal Abelson at the RIT GCCIS Dean's Lecture Series
Protests demonstrate growing demand for open access to research

It gets tougher and tougher to find subject matter as the whole virus-based movement limits tighten. But so far, I can still wander through the town of Grimsby, Ontario at will. As for keeping a safe distance from others, that is proving to be a piece of cake. Nobody (well, almost nobody) is out. In my searches the other day while enjoying a very bright morning, I decided to concentrate on bright colours in harsh light. In that vein, I spotted a large, blue dumpster behind the 40 House pub/restaurant on the main street of town. The bright blue was set off by the orange-brown rust and, combined with some textures, shadows, and geometry, became my subject. So another hard light, colourful abstract for the collection. - JW

PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: very slightly boost contrast and Chromaticity in L-A-B mode, slightly boost Vibrance, use the Channel Mixer’s green channel and slightly reduce the green channel’s green contribution, use the Shadows/Highlights tool to significantly recover highlights, apply a very small amount of noise reduction, sharpen, save. PP in free Open Source GIMP: use the curves tool to pull the black point to the left to meet the foot of the curve, use the hue-saturation-brightness tool to slightly increase the red-channel-only saturation and also reduce its brightness, sharpen, save, scale image to 6000px wide, sharpen, save, add fine black-and-white frame, add bar and text on left, save, scale image to 2048 px wide for posting online, sharpen very slightly, save.
During our visit to Paisley, Ontario, I did my usual wander around town to see if I could find any colourful subject matter. This is the front of the Quatre Directions restaurant on Queen Street North. The restaurant specializes in traditional Metis foods but, alas, I had no opportunity to sample the menu. Another time, perhaps. The late afternoon deep shadow helped to accentuate the blue paint scheme. Over the face are a number of feathers, fish and butterflies, rendered in a style reminding me a bit of a Dr Suess book illustrations. - JW

Taken using a tripod-mounted Nikon D800 fitted with an AF-S Nikkor 24-120mm VR 1:4.0 lense set to 120mm, ISO100, Daylight WB, Matrix metering, Aperture Priority Mode, f/8.0, 1/20 sec. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: set final image size to be 9000px wide, level image, enable Tone Mapping at default levels, increase Contrast and Chromaticity in L-A-B mode, use Tone Curve 2 in parametric mode to brighten the Lights, adjust White balance by shifting the Temperature to slightly more yellow to somewhat counteract the deep shadow blue cast, slightly increase Vibrance, sharpen (edges only), save. PP in free Open Source GIMP: use the Curves tool to slightly brighten the image overall, use the Hue-Saturation-Brightness tool to increase the Cyan channel saturation and also darken it a bit, use a non-destructive dodge/burn layer to brighten the green planter as well as the text in the window signage as well as the feathers, create new working layer from visible result, duplicate the layer and boost its contrast and saturation overall, add a black/transparent layer mask to that layer and then use a soft brush with white ‘paint’ to paint the feathers, fish and butterflies to show them against the bottom layer, create new working layer from visible result, fine tune Contrast a little, sharpen slightly, save, scale image to 6000 px wide, save, add fine black-and-white frame, add bar and text on left, save, scale image to 3000 px wide for posting online.
Looking back on some images taken on a very cold winter day in January 2015, I chose one of the old, digitally-dusty frames to process as it had been neglected for far too long. In Port Dalhousie (technically, the Regional City of St Catharines, Ontario), the Welland Canal entrance from Lake Ontario offers protection to ships making the transit via a pair of piers that extend out into the lake some 1000 metres. On the East side of the East pier, a man-made spit has been made from materials dredged during both canal construction and the periodic maintenance operations. Toward the far extent of the spit, sumac has established itself, albeit in a somewhat stunted form due to the constant winds off Lake Ontario. In the winter, those same wind deposit fine mist from the lake on the sumac branches and occasional seals in snow from a recent snowfall, as seen here. I spent time time out here freezing various appendages as I crawled around with tripod and camera to capture the scene on this day. - JW

Taken using a tripod-mounted Nikon D7100 fitted with a Nikkor 12-24m lense set to 12mm, ISO100, AutoWB, Auto exposure mode, f/8.0, 1/400 sec with an EV+1.00 Exposure Bias to compensate for the snow. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: turn Input Sharpening OFF, set final image size to be 9000 px wide, use the Graduated Neutral Density/GND tool to darken the sky a bit, set Exposure Compensation to EV+0.20 to slightly brighten overall, use the Tone Curve 2 tool in Parametric mode to slightly brighten the Lights (eg. foreground snow) and also very slightly darken the Highlights to retain detail, very slightly increase Chromaticity in L-A-B mode, very slightly boost vibrance, sharpen, save. PP in free Open Source GIMP: to tone down a bit if an excessive cyan cast to the lake water (particularly on the left) use the Hue-Saturation-Brightness tool to decrease the Cyan channel saturation, slightly increase overall contrast, sharpen, save, scale image to 6000px wide, sharpen slightly, add fine black-and-white frame, add bar and text on left, save, scale image to 3000px wide for posting online, sharpen very slightly, save.

Revisión del downloading MP3 tras las declaraciones de Bill Gates sobre Open Source, licencias CC y comunismo. Lo malo es que no recuerdo donde la encontré.
The Bando de Kvar (well, three of the four) met up at a local Grimsby, Ontario pool hall, Different Strokes, to discuss major world issues while reducing the world supply of potable fluids. Being a pool hall, it was necessary for a game to be played by the two members claiming the most ill-spent youth, Bando Paul and Bando Matt. With visions of Eddie Felson (Paul Newman) challenging Minnesota Fats (Jackie Gleason) in the 1961 film, The Hustler, the game was on. Eight ball, best two of three. Reality, unfortunately, fell a tad short of the Hollywood image and a protracted game evolved, with frequent utterances that would most certainly not meet with mother’s approval. Here we see Bando Paul in a quickly-cut-short attempt to run the table. Just another day of the Bando attempting to augment their misspent youth with a misspent adulthood. - JW

Tech Details:
Taken using a hand-held (actually, propped on the edge of the pool table) Olympus OM-D EM-5 fitted with an Olympus M Zuiko 14-42mm 1:3.5-5.6 lens set to 25mm, Intelligent Auto mode, Auto WB, ISO1600, f/3.6, 1/30 sec. PP in free Open Source RAWTherapee from Olympus RAW/ORF source file: set final image size to be 8000px wide, crop off some from the left side and also off the bottom (to reduce the vast/excessive expanse of green felt surface), convert to black-and-white and in so doing darken the green channel contribution and increase the red channel contribution using the Channel Mixer (in manual mode) to get a good base overall tonality, use the Graduated Neutral Density/GND tool rotated to cover the bottom of the frame/table surface and darken the table surface to better match the rest of the image, enable Shadows/Highlights and significantly recover highlights as well as slightly boosting the shadows, sharpen (edges only), save. PP in free Open Source GIMP: copy the image to four layers, top layer for arm adjustment, second from top layer for face adjustment, third from top layer for body adjustment and bottom layer for background adjustment, use the tone curve tool to adjust each layer to get suitable tonality in each (necessary because of the extreme lighting levels), create new working layer from visible results, brighten the cheeks and nose highlights using the dodge/burn tool on the highlights and then also brighten the whites of the eyes, save, scale image to 6000px wide, (did not sharpen again), save, add fine black-and-white frame, add bar and text on left, save, scale image to 2048 wide for posting online, sharpen slightly, save.
