As I hobble about trying to find photographic subject matter distance from my home base, I spent a bit of time looking at the flowers in my garden. After a brief rainfall, some of the classic July orange lilies provided an opportunity although not without some significant shifting around trying to fine an angle that isolated the three I wanted. A sure sign of it being mid-July here in Grimsby. - JW

Taken using a tripod-mounted Nikon D800 fitted with a Tamron 90mm 1:2.8 Macro, ISO100, Daylight WB, Aperture mode, Spot metering off central lily, f/16.0 for depth of field, 1/15 sec with an EV-0,67 exposure bias. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: set final image size to be 9000px wide, apply Tone Mapping at default levels, increase Contrast and Chromaticity a bit in L-A-B mode, use Tone Curve 2 in Parametric mode to darken the Darks sightly and then brighten the Lights, sharpen (edges only), save. PP in free Open Source GIMP: use the Hue-Saturation-Brightness tool to tone down the green saturation and then increase the red saturation, add a non-destructive Dodge/Burn layer and use it to slightly dodge/brighten the central lily and then darken/burn the buds along the left edge as well as the brighter branch (upper left background), sharpen, save, scale image to 6000px wide, sharpen, save, add fine black-and-white frame, add bar and text on left, save, scale image to 3000 px wide, sharpen, save.

This is the last shot of the night, or more correctly, this morning in Grimsby, Ontario along the South shore of Lake Ontario. I had been out comet hunting since the Neowise comet is currently visible in the ‘morning’ sky. But once it was lost in the brightening pre-dawn sky at the mouth of the Forty Mile Creek (The Forty), I was packing up and at the last minute decided to shoot the mouth of The Forty with the moon and Venus bright in the sky. Just a closing shot for what will be a sequence of comet images to come shortly. - JW

Note: If you check the EXIF data, the camera time used is Eastern Standard Time NOT Daylight Savings Time.
Taken using a tripod-mounted Nikon D800 fitted with an AF-S Nikkor 24-120mm 1:4.0 lense set to 24mm, ISO200, Auto WB (JPEGS had better colour and reduced the sodium vapour lighting colour casts), exposure determined by test shots to get desired tonality, Manual mode, f/5.6, 5 sec. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: set final image size to be 9000px wide, level horizon, enable the Graduated Neutral Density/GND tool and rotate a well as reduce feathering and shift down to cover upper right diagonal part of the frame and then brighten NOT darken the upper right of the frame, very slightly boost Chromaticity in L-A-B mode, enable Shadows/Highlights and then significantly recover highlights and slightly recover shadows, use Tone Curve tool in parametric mode to brighten the shadows a bit, apply noise reduction, reduce residual chromatic aberrations, sharpen (edges only), save. PP in free Open Source GIMP: use the tone curve tool to bring the white point left from default position and align it with the bright end (right) of the data curve, use the Hue/Saturation/Brightness tool to slightly boost saturation and clean the colours, sharpen, save, scale image to 6000 px wide, sharpen, 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.
Photo taken with this morning's waffles, for no good reason other than that I'm proud of them. This doesn't really show off the fact that it's really small! Smaller than an Altoids tin, for sure.

I'm taking a small break from building cameras to make an accessory or two. Here's my latest effort, an exposure meter (light meter, whatever you call it) powered by Arduino. My goals for this project were:
-Compactness (72 x 50 x 18mm - smaller footprint than than a credit card)
-Low cost (About $60 in materials)
-Large dynamic range (0.03 - 65000 lux, limited to about 1-65000 with current libraries)
-Information-rich display (Av, Tv, Sv, Ev, Lx, and system voltage on power-up)
-Simple controls (3 buttons, Av+, Av-, meter read, ISO (dual button press), save settings (dual button press)
So far, it works pretty well! Like any reflective meter, it will get a little confused by a bright sky - so you do have to be careful about where you point it to get a correct reading. As usual, this project is completely open source, so all of the necessary documentation and files can be found on my webpage!

While on a walk on the Princess Point Trail in the Royal Botanical Gardens (or simply the RBG to locals) in Hamilton, Ontario’s West end, I was admiring the Fall colours when I looked up and saw a maple tree with orange leaves accented in yellow along the veins. Now, a few days later, and following a rainy as well as windy weekend, these are not only a memory. - JW

Revisión del downloading MP3 tras las declaraciones de Bill Gates sobre Open Source, licencias CC y comunismo. Lo malo es que no recuerdo donde la encontré.
I was playing with a white styrofoam mannequin head in some test images and during a pause in those efforts, I had placed the head on top of a partially filled laundry basket/bucket or whatever it is called. That in turn was sitting on a heavily weathered pink farm chair which was also being used as a prop. Bright window light illuminated the face from the right. Viewing things from above, it looked a bit odd so, exercising my philosophy of ‘if it attracts your eye, shoot it’, I did. But colour was not a significant element in the image but light and shadow was, so I opted for a black-and-white/monochrome in PP. Treatment. Enjoy a bit of an odd-ball image. - JW

Taken using a hand-held Olympus OM-D EM-5 fitted with an Olympus M Zuiko 14-42mm EZ 1:3.5-5.6 lens set to 14mm, Intelligent Auto mode, Auto WB, Matrix metering, ISO1250 (Auto ISO), f/3.5, 1/60 sec. PP in free Open Source RAWTherapee from Olympus RAW/ORF source file: set final image width to be 8000px wide, crop a little off the right side to get rid of some bright background objects that intruded into the image, slightly darken image overall by setting Exposure Compensation to EV-0.30, enable Tone Mapping at default levels, very slightly increase contrast and then boost Chromaticity in L-A-B mode, use the Shadows/Highlights tool and significantly recover highlights in the foam head and also recover shadows, apply noise reduction, sharpen (edges only), save. PP in free Open Source GIMP: convert to B&W/monochrome using the colour desaturate tool and select channel mixer method in which the green channel is darkened and the red channel is brightened to get a good base tonal range, use the Contrast/Brightness tool to slightly boost contrast and then boost brightness a little, use the Tone Curve tool to very slightly darken the bottom (approx) 20% of the curve to make the background clutter less obvious and then slightly lift/brighten the top end of the curve being careful to avoid lowing out the highlights in the foam head, sharpen, save, scale image to 6000px wide, sharpen, save, add fine black-and-white frame, add bar and text on left, save, scale image to 3000 wide for posting online, sharpen slightly, save.
