One of the features of the Sk8 Park in Grimsby, Ontario is a group of small billboard-style panels specifically intended to host the artistic expressions of those visiting the site. As a result, graffiti is encouraged in places that are acceptable. Furthermore, periodic cleanup of the panels by town staff ensures regular refreshment of the subject matter. This image was taken in mid-February, the dead of Winter, so the snow-covered park was not in regular use and had not been for several months. The last round of painting had been ignored, likely waiting for Spring to get a refresh, with the consequence being the multiple layers of paint had weathered and flaked off leaving colourful abstracts when viewed up close. This section features and area with yellow and green patches. - JW

Taken using a hand-held Nikon D7100 fitted with an AF-S DX Nikkor 12-24mm 1:4 lense set to 12mm, Daylight WB, ISO100, Program mode, f/8.0, 1/250 sec. PP in free open Source RAWTherapee from Nikon RAW/NEF source file: set final image width to 9000px, adjust Tone Curve 2 in parametric mode by darkening the ‘Darks’ and ‘Lights’ slightly, enable HDR Tone Mapping and apply a light amount of HDR, enable Shadows/Highlights and recover highlights just enough that the ‘white’ areas of paint show detail/texture, boost contrast and Chromaticity in L-A-B mode, set White Balance to Daylight (5300K), boost Vibrance, sharpen (edges only), save. PP in free Open Source GIMP: increase overall contrast, fine tune overall tonality using the Tone Curves tool, sharpen, save, scale image to 6000px wide, sharpen slightly, save, add fine black-and-white frame, add bar and text on left, save, scale image to 2048px wide for posting online, sharpen slightly, save.

Taking a break from driving as we passed through Wauchula, Florida, I wandered around the back alleys (if you want to call them that in this relatively small town) and came across this old red brick wall (so Red Rule). Clearly it had gone through a number of modifications as the building’s function changed over time. There was even a bit of a shrub starting to grow in one of the arched windows at the top of the frame. I liked the repeating rectangular patterns and, of course, the colour. Taken in the mid-day harsh sunlight. Shoot it when you find it. - JW

Taken using a hand-held Nikon D7100 fitted with an AF-S DX Nikkor 18-105mm VR lense set to 70mm, ISO100, Daylight WB, Aperture priority, f/8.0, 1/200 sec. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: set final size to 9000px wide, level the lines of bricks, slightly increase contrast and Chromaticity in L-A-B mode, set colour balance manually to slightly warmer than as-shot (5300K), use the Highlight/Shadows tool to recover highlights and also recover some shadow detail, enable Tone Mapping at default levels, increase Vibrance very slightly, enable the Graduated Neutral Density/GND filter tool and rotate it and shift down to cover the bottom 1/3 of the frame which was a bit brighter than the top of the frame and then slightly increase strength the strength to darken that area, slightly darken overall by applying exposure compensation (-0.16 EV), apply a little bit of noise reduction, sharpen (edges only), save. PP in free Open Source GIMP: very slightly boost saturation and contrast, clone out a random piece of cable intruding at the top of the frame, sharpen, save, scale image to 6000px wide, sharpen slightly, save, add fine black-and-white frame, add bar and text on left, save, scale image to 2048 for posting online, sharpen slightly, save.
Do you see the kids on top of the bridge?
It took a bit of patiences to get a shot with MOST of the visitors out of frame.
Accompanied by fellow photographer, Leslie Polci, I returned to the gorge of ‘The Forty’ in Beamer’s Falls Conservation Area in Grimsby, Ontario to take another stab at capturing some of the fleeting Autumn leaf colours at their peak. Beamer’s is one of the many locations preserved by the Niagara Region Conservation Authority along the Niagara Escarpment and, fortunately, is within walking distance of home. People are fairly familiar with the Upper Beamer’s Falls and are under the impression it is Beamer’s Falls. They do not realize there is a smaller, but very nice lower falls some 75-80 metres downstream, and here the creek named ‘The Forty’ drops some 5-6 metres down the Niagara Escarpment into a rocky bed that then slopes more gradually Northward to empty into Lake Ontario about one kilometre away. We were pleased, albeit somewhat surprised, to find a reasonable water flow given the dearth of water flow at other area waterfalls I have been visiting recently. The long, dry, hot summer did take its toll but Beamer’s seams to have somewhat bucked the trend. - JW

Taken using a tripod-mounted Nikon D7100 fitted with a Nikkor 12-24mm lense set to 12mm, ISO100, Daylight WB, Manual mode mode, f/7.1, 124 sec (based on histogram result). PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: scale image to 9000x6000, adjust exposure to slightly brighten overall, adjust contrast and Chromaticity in L-A-B mode, slightly increase vibrance, sharpen, save. PP in free Open Source GIMP: slightly modify the tone curve to brighten the mid-tone portion of the curve, slightly increase contrast, adjust colour balance to get a more cleaner look, duplicate the image to a layer below the original working layer and adjust the tone curve to slightly darken and increase contrast of the hillside beyond the falls, disregarding the impact on the rest of the image, use a large soft-edged eraser tool to remove the upper hillside area from the top (original working layer) to reveal the better hillside area from the layer below, create new working layer from visible result, do some minor adjustments to the colour balance to remove a slight red cast, sharpen, save, scale to 6000x4000, sharpen slightly, add fine B&W frame, add bar and text on left, save, scale image to 1800 wide for posting, sharpen slightly, save.
Atwood, Ontario is a small village set in a rural-agricultural region in central Ontario. As is the case in many such small places, the downtown core has lost many of its businesses and there remain a mix of older houses dating back 100 years or so, generally lining the main street, with more modern houses set back in streets off the main street. Although some of the older houses are quite elegant, particularly if restored, others seem to be awaiting restoration. In this case, what was once the front porch has been closed in, perhaps to offer protection against the often very cold winters which are the norm here, or simply to gain additional living space. You can still see the original porch railings below the windows. Clearly in need of some attention to bring it back to its former glory, the porch offers a nice study in textures. - JW

Taken using a tripod-mounted Nikon D7100 fitted with a Nikkor 18-105mm VR lense set to 62mm, ISO100, Aperture Priority mode, f/7.1, 1/50 sec. HDR processing in free Open Source Luminance/Qtpfsgui: create two variants of the same image using only a single image rather than a more traditional multi-image-based HDR, making this Tone-Mapped rather than strictly HDR, create one using the Mantiuk'06 model to emphasize textures and another variant using the Fattal model to emphasize colours, setting as indicated below. PP in free Open Source GIMP: load the two variants as layers, set the blend to 50% to get a balance between the texture and colours, create new working version from visible results, adjust the colour balance to get a neutral grey in the weathered lower railing to the right of the porch, adjust colour saturation to reduce the red brick saturation which was too intense and also to boos the yellow saturation to get the porch looking better, slightly increase contrast, sharpen, add fine black and white frame, add bar and text on left, scale to 1800 wide for posting.

Technically not infrared, but a different spectrum filter.
The purple foliage comes from using a full spectrum converted camera with an 85A filter. NO color channel swapping or photoshop effects.
What makes this shot unusual (besides the filter) is that the fog is coming from the opposite direction from what it usually does.
Taken with a 650nm IR filter. using a full spectrum modified NEX-5N.
Post production:
3x exposure bracketed images were combined to remove noise and increase the dynamic range. Photomatrix software was used for this. (Highly recommend this product.)
For "Golden IR" effect. Simply swap the red and blue channels in Photoshop.
No masking or per-pixel manipulation was done.
