opensource photos on Flickr

I originally shot, edited and posted this image in 2014 (www.flickr.com/photos/jwvraets/14355503739/in/datetaken/ ). That version was done at a time when I did not have the benefit of the PP experience I have acquired in the intervening 6+ years. It is one of my all-time favourites, so much so that a 24/36 inch print hangs in my house. I wanted to see what I could do with that image given what I know now. The text below is from the earlier version except for the PP which I have omitted in this case. The result is a little different, mainly in that the new edit is less gritty/noisy and more finely detailed. Check them out for yourself and see which you prefer. Enjoy. JW

This is a detail from the Robin Hood Flour mill located beside the Welland Canal in Port Colborne, Ontario. This was taken at dusk while the sky colour was able to bathe the shadow side of the building in a violet light that worked nicely with the sodium vapour lighting. This scene strikes me as a bit of post-apocalyptic city-scape. Add the reflections in the glass-smooth waters of the canal and this is what you get. This image is another from the series made during our most recent Bando de Kvar (www.flickr.com/groups/2472126@N24/ ) photo outing where we go to the same place and seem to wind up with results that are quite different from each other. Fun and also an opportunity to feed poor starving mosquitoes, as it turns out. - JW

Alefia Greenhouses Orange Glow by JW Vraets

16 2

As I head out most days for a morning swim, I park my car where I can see the back of the cannabis greenhouses producing legal pot by Alefia Greenhouses in Grimsby, Ontario In darker and overcast conditions, the orange glow of the grow lamps inside the greenhouses also bathes the metal of what I believe are ventilation equipment, in a similar orange glow. This makes for an interesting colour blend of orange and a somewhat blue of the sheet metal and interesting shapes in this industrial architectural image. - JW

Ice-Capped Groyne Remnants by JW Vraets

15 2

Once again, digging into the archives and brushing off some digital dust, I pulled up an image never processed. I had to decide between a very subtle, pastel colour version of a somewhat more punch B&W/monochrome version a my target result. So, B&W, it was (although I may come back to a colour version for a very different look at some future time). This image was taken at Kelson Beach on the South shore of Lake Ontario at the West boundary of Grimsby, Ontario, back in the day (January 2021) before local bureaucracy elected to make life difficult for photographers in this part of town. At that time the groynes were well along their way to being destroyed by the combined forces of repeated shore ice formations, storms and age. The most damaged ones were only showing about a half metre of their former selves, and in the very cold weather had developed little ice hats or helmets, as seen here. The small details along the horizon are not skyline elements on the far shore but, instead, flocks of water birds well out into the lake. - JW

Sun Cutting Through Fog, Beamers Falls by JW Vraets

14 1

Another forgotten image from the archives, taken in 2015 but never processed…

This is another image from a mid-December day in 2015 when fog had blanketed Grimsby, Ontario in, predominantly, the area below the edge of the Niagara Escarpment and northward out to Lake Ontario some 1 km North. But in the area near the gorge of the Forty Mile Creek (simply The Forty to locals), light breezes carried the fog into the woods atop the escarpment and into the Beamers Falls Conservation Area lands. The sun’s rays were trying to penetrate the fog and created this scene. - JW

Date Taken: 2015-12-14

Tech Details:

Taken using a tripod-mounted Nikon D7100 fitted with a Nikkor 18-105mm VR lense set to 18mm, ISO100, Auto WB, Aperture priority mode, f/10.0, 1/500 sec. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: set final image size to be 9000px high, Enable the Graduated_Neutral-Density/GND tool and use it (rotated, shifted and feathering to cover the foreground rather than the sky and then brighten the foreground leaving the sky alone), enable Shadows/Highlights and recover a little of both highlights and a small amount of shadows, bring up a bit of Chromaticity in L-A-B mode, boost Vibrance a bit, sharpen, enable noise reduction, save. PP in free Open Source GIMP: use the Hue-Saturation-Brightness tool to desaturate the blue channel and thereby restore the fog colour to a near-neutral tone, duplicate the image to a new layer and boost contrast of the sky and then add a white/opaque layer mask on which I painted black in the areas corresponding to the foreground only, create new working layer from visible result, use the dodge/burn tool to burn/darken the darks only in the tree trunk (centre-foreground), sharpen, save, scale to 6000 pixels high, add fine black and white frame, add bar and text on left, save, scale to 2048 px high for posting.

Happy New Year, everyone.

It has been a privilege to share my pictures with you this year, and to look at your wonderful art.

Forgive me if I have left out your language from here - it has been completely amazing to be able to 'travel the world' and meet some wonderful people here and in person, learn about different cultures, and sometimes even to stop and chat.

I hope and pray that 2025 will be a year for hope and celebration for us all, no matter where we are. Happy new year, people =]

What better to do on a warm summer night than go out and take pictures (and then go for beer)? Exactly! This was taken around 22.30-ish, a little bit after sunset.

Its Alright Ma, Barton St E by JW Vraets

9

Another image for my ongoing project capturing Barton Street East in Hamilton, Ontario. This is one of the buildings I assume are becoming victims of gentirification in the area. The It’s Alright Ma is a record store located at 338 Barton Street East but a search on google indicates it is now permanently closed. Loved the red and black colour scheme. - JW

Sandbar At The Mouth Of The Forty by JW Vraets

7

On New Years Day 2025, as part of my effort to start the year off right with some photography in the immediate area of Grimsby, Ontario, I visited the small park at the mouth of The Forty, as locals call it, but is also known as the Forty Mile Creek. Under a heavy cloud cover, the sandbar at the mouth of creek as it flows into the South shore of Lake Ontario, was hosting a number of Ringbill Gulls and ducks, all taking advantage of the shelter this spot provides. The crane visible towards the right of the frame is part of a marina hidden behind the tree line. - JW

Caribana Dancer, Green & Pink – 2006 by JW Vraets

11 1

I once again delved into the early days of my transition form film-based to digital photography and found some images from Caribana in 2006. This is an annual Caribbean festival held in Toronto, Ontario in early August. For colour, and music, it is pretty hard to beat. I really doubt you can take bad photos there. Feathers, sequins, elaborate costumes in a parade lasting some 2 hours at any viewing spot. This was taken using a Panasonic Lumix DMC-FZ30 super-zoom camera sporting 8 megapixels of image data, which was pretty good for the time. But GAS (gear acquisition syndrome) has intervened over the years since this was my main camera. So, once in a while I revisit old images and subject them to my current workflow to see how they hold up. No RAW available because I did not use it back then. It worked out surprisingly well. - JW
