This is another image taken last week Friday during a snow storm that was dropping large, fluffy snowflakes in nearly dead calm conditions. Here you see the remains of one of the groynes (shoreline erosion mitigation structures) located along Kelson Beach which is immediately to the East of Fifty Point Conservation Area, on the shore of Lake Ontario. If you look two-thirds of the way up along the left side of the frame you can make out a bit of Fifty Point. Kelson Beach lies at the West limit of Grimsby, Ontario where it abuts Winona (read Regional City of Hamilton). After three days of cold weather, ice had begun to form on the piles that used to hold long horizontal beams. The curved/bent steel rods were used to hold those horizontal beams, but extremely high water levels in Lake Ontario coupled with several violent storms in Spring 2017 tore off the remaining horizontal beams.
As of the date of posting, warmer weather has wiped out the snow and ice so now I have to wait for another cold snap to revisit the area for winter photos. - JW
Date Taken: 2017-12-15
Tech Details:
Taken using tripod-mounted Nikon D7100 fitted with a Nikkor 12-24mm lense set to 15mm and with a 10-stop Neutral Density/ND filter attached, ISO100, Auto WB, Manual exposure, f/8.0 (based on test exposures and histogram), 25 sec (to smooth out the water surface and also ensure falling snow flakes did not record in the image). PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: scale image to 9000x6000, set exposure to +0.8 stops brighter than as-shot, level horizon, enable Graduated Neutral Density/GND filter and rotate and relocate it to cover the snow in the lower left corner and slightly darken that snow area, enable shadows-highlights tool and significantly recover highlights to get better detail representation in the brightest snow and ice areas and then very slightly boost shadow recovery to slightly brighten the shoreline gravel, slightly boost vibrance, sharpen, save. PP in free Open Source GIMP: slightly modify the tone curve to bring up the mid-tones a bit while holding the top 20% (i.e. snow ice detail) at default value and then slightly pull down the bottom 10% of the curve, slightly increase contrast and slightly boost brightness (to prevent darkening the darkest areas but boosting contrast in the mid tones a bit), use the colour balance tool to reduce a slight magenta colour cast (i.e. add green), sharpen, save, scale image to 6000x4000, sharpen slightly, save, add fine black-and-white frame, add bar and text on left, save, scale image to 1800 wide for posting online, sharpen slightly, save.
This is another shot of a mid-’60s (either 1967 or 1968 I was told) GMC (General Motors Corporations) pickup out in a field where it sits now, snow-covered, awaiting some renovations planned for the Spring. A bit of sunlight was hitting it revealing some nice rusty and crusty features that were a bit washed out as-found but I did see potential to do a bit of HDR and tone-mapped processing so I recognized an opportunity to make use of those skills after a hiatus of some 2 years or so. I wanted to take a break from the style of images I have been doing for a while now and this proved to be the break I needed. Not to everyone’s taste but regardless, here is the result. - JW
Date Taken: 2018-01-19
Tech Details:
NOTE: This image was made by using Luminance HDR processing of a single image file. Hence it is none-mapped/TM and not strictly HDR.
Luminance HDR settings:
Mantiuk version: pregamma_0.35_mantiuk06_contrast_mapping_0.05_saturation_factor_0.8_detail_factor_2
Fattal version:
pregamma_0.55_fattal_alpha_0.9_beta_0.9_saturation_1_noiseredux_0_fftsolver_1
This image was taken using a hand-held Nikon D7100 fitted with a Nikkor 50mm f/1.8 D lense, ISO100, Auto WB, Aperture priority mode, f/4.5, 1/320 sec. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: scale image to 9000x6000, level the image, set the exposure to 2/3 stop less (darker) than as-shot, increase contrast and Chromaticity in L-A-B mode, increase colour temperature (make warmer) to 5250K, slightly increase vibrance, sharpen, save. PP in Luminance HDR: create two tone-mapped versions of the image, one using the Mantiuk model to emphasize textures and another using the Fattal model to emphasize colours using the settings shown above. PP in free Open Source GIMP: load the the two versions of the tone-mapped image and blend them using 50% of each to get a nice balance of colour and texture, create new working version from the visible result, adjust the tone curve by darkening the bottom 10% and lifting/brightening the mid-tones and the brightest areas to get a plausible sunlit effect, boost overall contrast and brightness, reduce saturation slightly (yes, reduce it) to compensate for overly saturated TM results in the red (for rust) and cyan (for bent bumper) channels, do some fine tuning of the tone curve, sharpen, save, scale image to 6000x4000, sharpen, save, add fine black-and-white frame, add bar and text on left, save, scale image to 1800 wide for posting, sharpen slightly, save.
