Three Sisters - Pittsburgh by GTX-Media Three Sisters - Pittsburgh by GTX-Media
Panoramic of the "Three Sisters" bridges of Pittsburgh.

The three bridges are:
Roberto Clemente (Sixth Street)
Andy Warhol (Seventh Street)
Rachel Carson (Ninth Street)

The bridges achieved their name by being built very close to one another (within a four year span, 1924-1928), are the first self-anchored suspension bridges in the United States, and are the only trio of practically identical bridges.

Image composed using pseudo-HDR technique (deriving HDR from a single image).

It has been waaaay too long since we have chatted. So I'm gonna comment here instead :D 
This is freakin' AWESOME! :) I just love the perspective on this, it's fantastic. And it's such a unique way of photographing the city, well done!

OH MY! HI THERE!

So glad you like it. It was an idea that just HAPPENED.

I was walking along the North Shore there to go to Stage AE (a concert venue). I had to park a ways away to get free parking, but the trail is awesome to walk. As I was passing under that bridge though I just happened to look under it and notice the other two bridges in view. Instantly I thought "this would be an awesome picture...". At the time though, I was running late for the concert that I needed to photograph so I rushed on by. 

After the concert was done, there was still daylight, so I rushed back to that spot. I no longer had my tripod (the drummer of the band I was photographing needed to borrow it for later that evening), and I needed to get close to the water to get the heavy amount of bushes/shrubs out of the photo (you can just barely see one of the bottom right). I stood on the waterline's edge on rocks, stabled myself, held the camera vertically, and took all the photos without a tripod.

It was the only scenic shot I got that day, and the only one I've gotten in awhile. I was ecstatic with how it turned out when I got it home. I want to revisit that spot on a summer day and try again to get a better one. I think this really exemplifies Pittsburgh because of its history and these bridges are part of that history. :D

:D :D

That's a great story!! And amazing that you took that without a tripod as well! I think it's just one of those magical things that just came out of the perfect circumstances, ya know? You parked far away and ended up walking under the bridge, you had a concert so came back later and got some beautiful lighting...really really marvellous! 
Just wondering... is this image an HDRI? I was trying to figure out how to make those for a rendering I'll have to make later on for school.

I'm not sure what the "I" means in that, but it is an HDR. Each of the 24 images were manually processed in a pseudo-HDR fashion (HDR from a single image).

The downside is that I had to find a balance between overexposing to get the underside of the bridge to come out and underexposing to get the sky to come out. Had I had my tripod, I could've done a proper 5 level bracketing to get the exposures perfect.

The software I used is in the description: "Photomatix Pro 3.2 (HDR Processing)"

Haha I believe 'I' just stands for 'image'. =P 

Hm I see what you mean. I recently had to take some photos in the downtown area near school without my tripod, and i was going around trying to find flat surfaces to put my camera on! :meow: 

Oh! I was just going to use Photoshop... do you know if that'll work?

It can, but I have never used it, so I am not sure how it would work.

People from Pittsburgh are absolutely LOVING this piece. I'm starting to get into the city more and am learning about what makes Pittsburgh the city it is, and these bridges come up in conversation regarding the city's history constantly. I by chance saw this shot (I never knew the North trail went under the bridge here), and just HAD to get it. :D

Cool shot. Hand held or tripod?
