As we over here in Grimsby, Ontario continue with our efforts to minimize our risk of infecting others or being infected ourselves, I have been looking around at things that catch my eye as I look for possible images and keep doing things that are part of my ‘normal’ life. I happened to pass a potted shamrock sitting on the counter below a kitchen window and noticed the undersides of a somewhat-too-dry plant were showing off a rich magenta colour. The magenta is a nice contrast to the green top surface of the leaves, as they should given they are on opposites sides of the colour wheel. Popping on my macro lense, I tightly framed the sweeping curves to capture the colours, shapes and the light reflected and transmitted by the leaves to yield this abstract. Keeping busy in the house. - JW

Tech Details:

Taken using a tripod-mounted Nikon D800 fitted with an Tamron 90mm 1:2.8 Macro 1:1 (272E) lense, ISO100, Daylight WB, Aperture Priority Mode, f/11.0, 1/3 sec with an EV-2.67 exposure bias (to avoid blowing out highlights). PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: use tone curve 2 in parametric mode to darken the shadows and get a clean black background, slightly boost contrast and Chromaticity and reduce lightness to get better magenta in the leaf underside in L-A-B mode, slightly reduce Vibrance mainly to tame the magenta, use the Shadows/Highlights tool to recover highlight detail, apply noise reduction, sharpen (edges only), save PP in free Open Source GIMP: use the hue-saturation-brightness tool to slightly reduce the saturation of the magenta channel and also darken it and then slightly boost saturation of the green channel and darken it, sharpen, crop a bit of the left side (resulting in an image 7000px wide) to better balance the image by removing a bit of excess black background, save, scale image to 6000px wide, save, add fine black-and-white frame, add bar and text on left, save, scale image to 2048 px wide for posting online, sharpen very slightly, save.

This is another image from last week’s morning wander through downtown St Catharines, Ontario, armed only with my cell phone. Along the West end of King Street is a building that presents a conventional brick face onto King Street but is painted in a light, pastel blue (cyan?) on its West and East walls. This shows the East wall. A section of the blue stucco has been lost exposing the underlying brick wall. Breaking up the blue of the door is a bright orange ‘tag’ (I hesitate to call it graffiti) which is a distinctive colour contrast to the blue wall. The overall impression is of a Mediterranean themed building. - JW

Tech Details:

Taken using a Samsung Galaxy S5 mobile phone in the default (fully auto) mode but just for general interest that means it was shot using the 4.8mm (31mm classic 35mm film equivalent) lense at fixed f/2.2, ISO 40, at 1/176 sec to produce a jpeg file. PP in free Open Source RAWTherapee from Samsung jpeg source file: set final image size to be 9000px high, correct perspective, crop a little off the bottom of the image (to get rid of foreground details), brighten overall by setting Exposure Compensation to EV+0.35, use Shadows/Highlights to tone down the highlights a bit, increase Contrast in L-A-B mode, very slightly increase Vibrance, (no sharpening), save. PP in free Open Source GIMP: save, scale image to 6000px high, add fine black and white frame, add bar and text on left, save, scale image to 3800 high for posting online, sharpen very slightly, save.

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.
