CN8828 Passes Through Grimsby – (HDR/Tone-Mapped)
Over the past year, trains have been in the news quite a bit across Canada, and for all the wrong reasons. Trains, mostly, but not exclusively, freight trains, have been going off the rails with consequences ranging from property damage to spills of noxious materials to serious human tragedies (look up Lac Megantic). In most areas, train service is not near major residential areas, but in Southern Ontario, railways pass through some of the most heavily populated areas in the country. Grimsby, Ontario is one such area. Nestled below the Niagara Escarpment to the South and Lake Ontario to the North, Grimsby represent s pinch-point only about 1.5 km (about 1 mile) wide though which a large array of services including a major highway, a major electrical power corridor, and telecom run, and which is built up sold between the two natural boundaries. Through the middle runs a busy rail line linking the industrial areas of Southern Ontario and the North-Eastern USA, with all the associated movement of potentially dangerous cargoes. An accident here could have very serious consequences. It is hard, at times, not to reflect on the current state of rail safety when you live so close to the tracks. - JW
Tech Details:
This is a single image processed using HDR software. Consequently, only the tone-mapping stage comes into play and the image is tone-mapped rather than strictly HDR.
The original image was taken using a hand-held Nikon D7100 fitted with a Nikkor 55-200m VR lense set to 200mm, ISO100, Aperture priority mode, f/8.0, 1/80 sec. HDR processing to make use of the tone mapping stage was done in free Open Source Luminance using the Mantiuk '06 operator to emphasize the textures rather than colour, and also to bring some life back into an image suffering from a veil of atmospheric moisture due to the proximity to Lake Ontario. PP in free Open Source GIMP: applied the levels tool in auto mode to do a basic tonal range and colour balance, further adjusted colour balance to remove residual blue and green cast, boost overall contrast slightly, select the orange area at the front of the locomotive and reduce saturation slightly and then boost contrast a bit as well, sharpen, add fine black and white frame, add bar and text on left, scale to 1800 wide for posting.
