This week's picture was taken from a walkway underneath an arched, causeway bridge on the Indian River Lagoon. Even though the bridge is mostly over water, I didn't try to include any in the picture because I thought the form of the concrete supports was the most important thing and it didn't need any context beyond that.

I've photographed a few of these cookoffs at the santa cruz beach boardwalk before and had planned on doing so again this weekend although I really don't like doing it because it's just waaaaay too crowded for my taste (good for businesses in the city though). anyway, I thought I might be able to combine this challenge with the cookoff. I figured I might be able to find a used cup sitting on the ground and take an artsy-fartsy shot of it. but although I looked for quite a while, either people weren't giving them up or everyone was doing a nice job not littering. so I decided I'd try to convey some of the busyness as well as my location. had to stop the camera down and really slow the exposure values to get the needed motion blur as well as wait for the medallion to be seen but still have enough feet in the pic to seem busy.

For this photo, after a couple of days thinking how to tackle it without making an empty architectural shot, the idea of progress and foundation became the center subject. Reminiscing over graffiti art all over concrete in our modern world, and how concrete is fundamental, wanted to bring it back to the source of mankind expressions. Rock paintings contrasts over concrete in a way that could be not so obvious. Both foundational and both still present through street art. Shooting this photo was a creative challenge that proved very entertaining. Not being an artist, painting this with watercolors in the balcony's floor was a curious project to say the least.

This is a picture of an old wall-mounted concrete water fountain outside which has been in disuse for many years. I moved in close and used a relatively large aperture to create a shallow depth of field. Minor adjustments were done in Lightroom 4 to soften the contrast and lighten the exposure for a high-key, soft, monochromatic look.

"The Concrete Canyon"
I was walking outside, thinking about this challenge on gizmodo, when I came upon an interesting fissure on the concrete sidewalk I was walking on. When I looked closer at it, it looked almost like a miniature canyon. So, I took some shots with my camera, and went back inside and did some work in photoshop to make the crack look as if It was actually a canyon in a desert setting.

When the contest was announced, i was immediately reminded of "Concrete Sentinels" of a local parking garage... Friends have complained that once one sees the anthropomorphism of the eyes/nose that they can't see the formed concrete as anything but silent watchers.

During a stroll through town (Basel, Switzerland) last Friday I remembered the Concrete Gizmodo Shooting Challenge and decided to have a go. Passing by this concrete school (!) building I thought its forbidding façade kind of reflected the icy winter climate that surrounded me. Left the tree at the far end on purpose, to leave some life in the picture. Glad my frozen fingers managed to press the shutter button...

It happened to be a somewhat sunny and warm afternoon so that alone was inspiration enough to get outside and do some experimenting with the recently arrived DX extension tubes. The contest theme was aptly timed as in the fall I had a concrete patio freshly poured in my backyard. The photo is of one of the control cuts in the slab. The cuts are still "crisp" when viewed at a standing distance. The slab at this point was mostly dry but the control cut was still expelling moisture which is adding to the dark to light gradient from the cut and outward.

This was taken in my neighborhood just after midnight. I don't normally go out late at night looking for photos but I just received my new 10-20mm lens and couldn't wait to use it. (It goes to 10mm which is better than 11 in camera talk) This is the an alley area between a few apartment buildings. Since this was an impromptu trip I left without my tripod. I used higher ISO and held my breath literally.

Daytime Nap.

This shot was taken at a Buddhist graveyard in a town outside Kyoto, Japan. This sleeping Buddha, a large (20 foot wide) concrete statue at the graveyard's entrance, puts visitors at ease as its tranquility balances out the somberness of death. I particularly like how the clouds on the left resemble a pillow. No color correction was done at all, but photoshop was used a bit to remove a couple of tree branches that encroached on the clear sky.

I was returning back from an event at Thamel, Kathmandu. Noticed this crack on the wall at 'Narayanhiti Palace' (palace of last king of Nepal). This concrete has seen everything, the kings, the revolution, changes and now converted museum. Much to the pressure and environment and somewhat to the fallen regime the concrete tried to hold whatever it could and now awaits renovation ... A wall with history and story.

Not too far from my house is a development that has been unfinished for years. I headed there to take pictures of the foundations of the houses. This shot is of a bolt left sticking out of a wall, undoubtedly intended for some purpose to which it will never be put.

Out on a Sunday afternoon running errands... my husband and I were pondering what would make a good concrete shot - I captured his shadow in one quadrant of a piece of textured sidewalk.

This is the first shooting challenge I submit anything: partly because this one does not require any fancy equipment or skill and partly because I had already an idea. So I took my little compact camera to a walk around the block, trying to find my spot. In the challenge's description, it was written concrete is a " substance that's harder than rock." Yes, that's true, but we also know - and very well - that nature's power cannot be completely controlled by men. It was not hard to find a plant like this one: super fragile, growing wild, reaching the sun through a crack in the concrete sidewalk. Nature doesn't care. Picture taken with my compact Samsung WB700, ISO 80 and 1/4 s shutter, with a vignetting effect applied directly in the camera, and no further computer manipulation. Excuse the possibly bad english, it's not my native language and I'm falling asleep as I write.

This is the underside of a bridge near my home. I took twenty or so shots over half an hour looking for the right angle. There were some mossy pics, some with the creek below, but something about this one just screamed CONCRETE for me, so I went with it.

Hairline Crack

My driveway looks smooth to the naked eye with the exception of a small hairline crack in one corner. I wanted to get a closer look. I used the lights from my light box shooting challenge to light up the scene. I found that the zoom lens would not stay in one spot long enough to snap a photo, so I had to go to the prime lens. I had the tripod set up with two legs short and one let extended long to allow the camera to get closer to the scene than the standard tripod setup would allow. I still couldn't keep the camera still enough for a long exposure, so I opted to use a high ISO .

So I shot a similar shot to this in high school when I was learning and developing 35mm black and white photography for a project on "lines" and will never forget how excited the teacher was to see my finished product. When I saw the Concrete Jungle topic my first thought was to go reshoot this now years later and see what I could come up with. I didn't get there until sundown and couldn't find any light under the bridge so I had to overexpose and underexpose by two stops (along with a normal exporsure) to fill in the background and the concrete. Figured since I was going to have to merge them I'd go with a funky edit that blew out the background and this was the result. Shot on a Canon XTI (400D) with the kit 18-55mm lens, ISO 400 @ f/5.6 over and under exposed by two stops, merged in Photoshop with a NIK plugin.

Every day I walk along this sidewalk and I notice it. Mostly I notice that a section of it between my apartment door and my car is pretty sunken. It needs to be mud-jacked and has been in the past. Yet it is there, sunken into the ground, creating the biggest damn puddles every time it rains or snows and melts. I hate the sidewalk and wish the apartment management would take care of it. However, when this assignment came a long, I remembered how as a child I would lay on my stomach on the hot concrete and look really closely at it and see the boring slab as an enormous and detailed terrain navigated by the tiniest of insects, particularly ants and those little red clover mites. If it weren't February in Wisconsin, I would have looked for some of either. The concrete world is complex, and really beautiful when you look at it through tiny eyes. It's immense and chaotic. It is subject to decay like all things. However strong it is, salt can weaken it and water can break it wide open simply because of physics. It is therefore frightening that so much of the world's infrastructure is made of this stuff.

The best place for interesting concrete in my little town of Maysville, KY is at Limestone Landing. The Landing is one of the original ports on the Ohio River, and was important for the settlement of Kentucky. This picture is of the concrete pillars for the dock at Limestone Landing. The railings have been removed, I assume in anticipation of spring flooding. What remains are several pillars in an arrangement that reminded me the statues of soldiers at the Korean War Memorial in Washington, D.C.

Shot looking north from the top of Rare View bar at Lexington - one of the best views I've found of the urban concrete jungle that is NYC. Managed hang the camera over the edge to get the shot without any foreground and without getting spotted by the staff! Converted to a high contract B&W in post, added grain for a bit of grittiness and darkened corners to draw the focus into the center and the Empire State.

Here is my last minute entry for the concrete photo contest. This was taken with my Sony A77 and the 16-50mm lens zoomed all the out to 50mm,ISO 400 with the aperture at f5.6 and a 1/125th shutter speed. I knew the second I saw that contest that I wanted to photograph the really cool concrete holding the spillway together at Lake Indigo (http://goo.gl/maps/fEive) in my neighborhood. This was taken about as close as I could get, and then I enhanced the clarity, sharpness, vibrance and saturation, to get a shot that to me looks like a false color shot NASA would have taken of a plateau on Mars.

This is one is on the ceiling of my bedroom. It is a great trick...errr... way invite women into my bedroom. I just say "Would you like to look at my ceiling and tell me what you see." You would be surprised how many women do indeed get on my bed to see the rorschach on my ceiling.
