Night Suspension

Taken near the south tower of Lions Gate Bridge, a sulfur lamp shining on the cables, taken while laying on my back on the vibrating bridge deck while K waved traffic around me. Ok, just kidding about that last bit.

I tried a number of exposure/aperature combinations, but nothing was really working. Then it occured to me that since there was virtually no color in the image, it should be converted to black and white. And because it's black and white, with no detail in the emptiness, I could crank up the ISO, knowing the chroma noise could be flushed out by raising the black point in post-processing.

Blair Witch

There is something very enjoyable about watching young children leap before looking. Every step, every dark tunnel, is more adventure than cause for concern.Posted by Picasa

The Green Room

Back in the day, black and white film was occassionally painted to give it a faux-color appearance. This one I did in reverse - bleeding away most of the reds and blues, leaving only a little green.

Taken near Beaver Lake, in Stanley Park.Posted by Picasa

Bottoms Down

Yes, I freely admit this has "greeting card" written all over it. About the only thing missing is a cat hanging from a branch. But somehow images seem much less corny when they involve your own kids.

I really like the tonality, at least in print. This is another of those images that just doesn't seem to want to come right on the screen.Posted by Picasa

Whytecliff Park, West Vancouver

Whytecliff Park, near Horseshoe Bay. A near-miss, I think. The hillside was very rocky, the raven was a little twitchy, and I just couldn't quite get the exact right position I was visualizing. And in all the mucking about, I missed the Decisive Moment of Light.

Still, I'm fond of it. I can imagine Shakespeare looking at a view like this before putting pen to paper and writing Macbeth.Posted by Picasa

Whytecliff Park, West Vancouver

Second in a series from Whytecliff Park. Dealing with this image really made me miss my old darkroom. The 80dpi we get from our screens just can't capture the textures in the clouds or the detail in the rock shadow. The contrast limitations of a typical LCD screen are also shown in the highligts midway up the righthand side: to get any "hotness" in the whites requires blowing-out ("clipping") more of the image than should be necessary.

This image comes with a little poignancy, as the good friend I was with at the time slipped on the hillside just to the left and cracked a couple of ribs. But he assures me he will survive!Posted by Picasa

Beach Detris

This image begs to be printed. A friend blew it up to 11x14 on a Lightjet, and it looks fantastic! It completely captures the feeling of decay, rust, abondment. Unfortunately, it doesn't come across as well on a typical display.

I'm going to invoke editorial privilege here. I love my Canon digital SLR. It gives millions of pixels, at 12 bits per pixel. But I'm a black&white shooter at heart, and the color mask and anti-aliasing filters on the sensors are costing roughly 2 bits per pixel. That's 4x the dynamic range! A B&W-only camera may be a niche product (though I'd argue with that, since B&W film was always more than a niche), but it would be a profitable one. Hopefully somebody will fill that need.

Displays are another issue. JPEG is fine for many things, but at 8-bit color depth we lose a huge amount of color and luminance information everytime we convert from RAW. If HDR displays became prevalent, perhaps users could be nudged towards a better format. Or perhaps JPEG itself could be extended.

Ok, I'm off my soapbox. Thanks for listening. :)Posted by Picasa

Scale-model Effect #1

First attempt at recreating the tilt-shift "scale model" effect. By minimizing perspective angles, mimicking selective lens blur and playing with the contrast levels, I think the image got pretty close. At least for a first attempt. This kind of thing really screams out for an HDR display; the way the tone curve is manipulated really pushes what a typical LCD monitor can do at the dark and light extremes. Posted by Picasa

Scale-model Effect #2

Second attempt at the "scale model" effect. Looking down on False Creek from a 19th floor Yaletown condo. This is a very good color set for the effect, but I think it would work better if the image was horizontal. But for a second attempt, I'm reasonably happy. Posted by Picasa

Scale-model Effect #3

The latest attempt at achieving the "scale model" effect. I'm fairly happy with it, thought I think it would look more right - or is it more not-right? - if the car in the intersection were a lighter color. That would allow it to throw off better specular highlights. Posted by Picasa

A Picasa Miracle

Normally I process RAW data from the camera sensor in Adobe Camera Raw. This image, however, was created in Picasa. To be honest, I don't know what happened. It is a sunrise shot looking back over the city, and I cannot find any way to recreate the colors when using Adobe's RAW converter. In effect, even though I have the negative, I no longer have the right developer to duplicate the print! Posted by Picasa

Vaseline

This doesn't come across very well at all at web size. It was an attempt to play with coloring by applying various translucent "muck" to the front lens element. Obviously, this is not something you'd want to do with a nice lens! An alternate way to get effects like this is to shoot a textured surface (vaseline smeared on a glass plate, off-white plaster wall, etc) and then combine the texture with images inside Photoshop.Posted by Picasa

Pinhole

Our son, Sasha. I am currently experimenting with home-made...err..."custom"...lenses. This was taken with a pinhole, effective aperature of about f/600. Like any camera obscura, there is no focus ability, although I am attempting to marry the pinhole with a cheap old EF-mount lens to see if some sharpness can be obtained. What I really like about the experiment so far is the coloring.

There are small specks visible on the image. That is from dust and detris on the sensor itself. Normally they aren't visible, as they specks are very very small, but at such a tight aperature all kinds of wonky diffraction effects can happen.Posted by Picasa
