Ever fancied yourself a robotic arm developer?

 

We've released all the files and details needed to build your own and get developing and most importantly improving.

In last May’s road trip through Colorado, Utah and Arizona, we were beetling South on highway 191 from Maob Utah toward Monument Valley and in entering the North end of Monticello, Utah we stopped for gas at the intersection of 191 and W400n (you can just see it along the right edge of the frame). While the car was being filled, I briefly abandoned my fellow travellers and crossed the street to an derelict, and now for sale, gas station/garage. I had notice the mural of the horse silhouette on a pinkish background and as I got closer, the yellow puddles, clear blue Southwest sky and the building colours came together for me. A couple of quick shots and we were off again. Hard to beat Southwest colour. - JW

 

Date Taken: 2017-05-12

 

Tech Details:

 

Taken using a hand-held Nikon D7100 fitted with a Nikkor 18-105mm VR lense set to 18mm, ISO100, Auto WB, Aperture priority mode, f/11 (I wanted wide depth-of-field - puddles and building ), 1/100 sec. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: scale (strictly speaking set the final size to) image to 9000x6000, set exposure to ¼ stop brighter than as-shot, enable shadows-highlights and recover highlights (mainly for the clouds) and also bring up shadows to help brighten the heavily shaded face of the building, boost contrast and Chromaticity in L-A-B mode, adjust colour balance to set colour temperature to 5140K (i.e. warm slightly), slightly increase vibrance, sharpen, save. PP in free Open Source GIMP: adjust overall tonality using the tone curve to get a reasonable base tonality in the sky and foreground, duplicate the image and apply a black/transparent layer mask to which white ‘paint’ was applied over the building face and its shadow so I could adjust the building tonality without altering the tonality of the rest of the image, use the tone curve to brighten the building face, create a new working layer from the visible result, slightly increase saturation to clean up the colours, 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, save.

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.

 

Last winter, while on a wander through downtown St Catharines, Ontario, I came across a covered pedestrian walkway on St Paul Street. It was there to protect people from the construction activities that were part of Brock University expansion into the downtown core. The blue was striking enough by itself but the yellow streaks provided a nice accent. It took a while to get a shot with no people in it though. But patience is its own reward I've been told. - JW

 

Date Taken: 2014-01-12

 

Tech Details:

 

Taken using hand-held Nikon D7100 fitted with a Nikkor 18-105mm VR lense set to 105mm, ISO450, Aperture priority mode, f/6.3, 1/160 sec with an EV-1.0 exposure bias (to hold detail in the highlight areas). PP in free Open Source RAWTherapee: increase exposure slightly, enable highlights and shadows and pull highlights own as well as boost shadows, slightly boost vibrance, bring up black level very slightly, sharpen. PP in free Open Source GIMP: crop off a bit of the left edge to get rid of distracting background details visible through the frame, slightly increase contrast, boost yellow channel only saturation and brightness, sharpen, add fine black and white frame, add bar and text on left, scale to 1800 wide for posting.

Back on the other side of Summer (Spring of this year) I was out on one of my periodic walks through Grimsby, Ontario and in so doing I walked into a small parking lot behind a local restaurant on Ontario Street, Cibo Osteria. What drew me there was the red-painted brick wall with a nicely textured plywood panel fastened over a lone window. The combination of the various rectangles a well as the red paint (hence Red Rule) picked up on two recurring themes in images I capture. Add this one to the list. - JW

 

Date Taken: 2021-04-03

 

Tech Details:

 

Taken using a hand-held Nikon D800 fitted with an AF-S Nikkor 24-120mm 1:4.0 lense set to 65mm, ISO100, Daylight WB, Matrix metering, Aperture Priority mode, f/6.3, 1/400 sec with an EV-0.33 exposure bias to better represent the ‘dark’ red wall. PP in free Open Source RAWTherapee from Nikon RAW/NEF source file: set final image size to be 9000px wide, slightly brighten the image overall by setting the exposure compensation to EV+0.37, slightly boost contrast in L-A-B mode, set the white balance by sampling the white strip below the plywood, slightly boost black level, apply sharpening (edges only), save. PP in free Open Source GIMP: slightly increase contrast, sharpen slightly, save, scale to 6000px wide, sharpen slightly, save, add fine black-and-white frame, add bar and text on left, save, scale image to 3000 px wide 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.

Just recovered some files I thought had been lost with a computercrash several years ago. These are from 2006 and were shot with the venerable Canon Powershot Pro1

After buying a batch of filters from ebay. I found the 85A + 85 filters (combined) give an interesting effect. So, I took a walk around the block shooting various things.

 

The white balance was adjust in-camera when the photo was taken. I also used bracketed photos and HDR to increase the dynamic range.

 

Notice the hill in the background still has green grass.

This was taken earlier in the winter (such as it was) and shows Lake Ontario as viewed from a small part adjacent to the old pumping station in Grimsby, Ontario. At this time the water was, atypically, dead flat with a fog bank sitting off shore and the sky had a couple of open areas letting in some nice late afternoon pastel light. The seagulls were taking advantage of the calm waters and resting a ways off shore. The previous few days had a constant breeze blowing in off the lake and the fine moisture droplets it picked up deposited themselves on the rocks placed along the shore in an attempt to help stabilize the erosion issues common in this area. Although the image was originally conceived as a colour image, the pastels captured simply did not meet my expectations so I decided to go with a black-and-white conversion. - JW

Taken using a hand-held Nikon D7100 fitted with a Nikkor 18-105mm VR lense set to 18mm, ISO100, Auto WB, Auto Exposure mode, f/11.0, 1/80 sec. PP in free Open Source RAWTherapee from TIFF file: scale image up to 9000x6000, enable Graduated Neutral Density/GND tool and balance tonality of sky and foreground, brighten image by increasing exposure slightly, boost contrast, increase vibrance slightly, slightly increase Chromaticity in L-A-B mode, slightly increase vibrance, rotate to level horizon, remove lense distortion, remove slight chromatic aberration, enable sharpening, enable micro-contrast, enable noise reduction, save. PP in free Open Source GIMP: slightly modify the tone curve to brighten the brightest portions slightly, convert to black-and-white/B&W using the film simulation tool and the Ilford Delta 100 model, use the dodge-burn tool to brighten/dodge only the highlights on the rocks and in selected locations in the water, save, scale image to 6000x4000 (my preferred working size for images intended to be posted online), sharpen very slightly, add fine black and white frame, add bar and text below the image, save, scale to 1800 wide for posting, sharpen very slightly, save.

开源商用要过几道坎

 

我一点也不怀疑开源软件将被大量的使用在商业环境,一点也不怀疑很多公司将利用开源软件获得商业的成功。我所关心的是,在这个不可逆转而且正在到来的大潮中同,我们将以什么样的姿态去面对和参与。就像是一个丰盛的晚宴,现在开胃菜已经吃得差不多了,主菜正在摆上餐桌。如果再不入席,那么品尝的就只能是残汤剩饭了!

 

当然开源商用也面临着诸多挑战,但是很明显这股浪潮是不可阻挡。人类历史中没有任何一次进步是轻而易举的,而恰巧这次进化我们可以参与其中,这是多么大的荣幸。

 

我想一定可以做些什么,当然你也可以选择等待发生什么。开源商用,请用不要迟到!
