As the Fall season progressed, the crab apple had shed its leaves and all but a couple of the crab apples. I captured this solitary survivor by positioning myself to get a yellow maple tree (from across the street) as the background, yielding a red on yellow, minimalist composition. - JW

PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: set final image size to be 9000px high, crop to a 16:10 format, apply Tone Mapping at default levels and then apply Dynamic Range Compression, use Tone Curve 2 in Parametric mode to darken the highlights and lights, use Shadows/Highlights to recover some highlight detail in the crab apple, slightly boost Vibrance, slightly increase Contrast and Chromaticity in L-A-B mode, use the Graduated Neutral Density/GND tool to darken the tree branch inn the top right, apply a bit of noise reduction, sharpen (edges only), save. PP in free Open Source GIMP: use the Hue-Saturation-Brightness tool to boost yellow channel saturation slightly and boost it brightness, adjust the Colour Balance by decreasing the green, use a non-destructive Dodge/Burn layer to darken the branch in the top right, sharpen, save, add fine black-and-white frame, add bar and text on left, save, scale image to 6400 px high, sharpen, save, add fine black and white frame, add bar and text on left, save, scale image to 3400px high for posting online, sharpen slightly, save.

Internet is about sharing files and informations, not keeping them in greedyness and ego.
A couple of years ago, I was passing through Smithville, and stopped to check up on the status of the then long-closed, and increasingly derelict, feed mill. The two big silos have continued to corrode and the scabrous rust as well as the lichens continue to expand their presence on the well-faded blue-green (teal?) paint job. The ladder on one of the silos remained, albeit in a very rusted state. The colours still appeal to me and I intend to continue my periodic visits in anticipation of their likely ultimate replacement with more housing. - JW

Taken using a tripod-mounted Nikon D800 fitted with an AF Nikkor 70-210mm 1:4-5.6 lense set to 125mm, ISO100, Daylight WB, Matrix metering, Aperture priority, f/8.0, 1/30. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: set final image size to 9000 px high, use the Graduated Neutral Density/GND tool rotated to cover brighter right silo and darken that area to make it less of an attraction to the eye as well as better balancing its tonality with the right silo, increase contrast and Chromaticity (slightly) in L-A-B mode, recover shadow detail by using the Shadows/Highlights tool, slightly boost black level, further boost contrast and reduce saturation, slightly, sharpen edges only, save. PP in free Open Source GIMP: increase the contrast and slightly darken the frame using the contrast/brightness tool, add a transparent layer above the image layer and use it as a non-destructive dodge/burn layer, darken/burn the right edge to reduce its brightness, sharpen and save, scale image to 6000px high, save, add fine black-and-white frame, add bar and text on left, save, scale image to 3000 px high for posting online, sharpen very slightly, save.

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

Tech Details:
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, two aut bracketed exposures at 5 sec and second at 10 sec with an exposure bias of EV-2.33 for both exposures. HDR processing was done in free Open Source Luminance/Qtpfsgui using the Mantiuk06 tone mapping operator to extract textures, using settings as indicated below. PP in free Open Source GIMP: adjust the tone curve to pull the black point to the right to meet the limit of the data curve, pull down the bottom 1/4 of the curve to darken the darker areas of the image, pull up the top1/4 of the curve to bring the lighter areas up to the original level, slightly increase overall contrast, load the original base image as layer below the working layer, use a soft-edged eraser tool to remove the reflected lamp areas from the working layer and thereby remove the unsatisfactory artifacts from the HDR processing, similarly clean up the lights on the building, create a new working layer from the visible results and then duplicate it, significantly increase the contrast of the lower of the two layers just created and also adjust its brightness to get improved tonality inside the windows disregarding the impact on the rest of the image, use a soft-edged eraser tool to remove the windows from the top layer to reveal the improved window detail from the layer below, create new working layer from visible result, sharpen, add fine black and white frame, add bar and text on left, scale to 1800 wide for posting.
