This is a shot of downtown Louisville, KY. I set up in a picnic area across the river in southern Indiana. On a side note, this was a pretty good first time out for my new Tokina ultra wide lens.

One of the greatest blessings of living on an island is yearlong warm weather and daily front row shots to beautiful beach front sunsets. I took this shot over a 10 minute span toward the tail end of the sunset 'golden hour'. As you can see it's a gradual transition from the pink sunset to a calming evening in East Agana Bay. Other than the beauty shown in this photo I think the most impressive portion of this photo lies in the fact that no color correcting or extra editing, besides the panoramic stitching, was done to bring this photo together.

I decided to take my family with me for this challenge, I decided to shoot at Brooklyn bridge park because of the awesome view of the NY skyline.
After making my family starve for about three hours, this was the result. I used the tutorial posted to blend the images.
The right side was taken at about 530pm when the sun was going down and the left side was at about 830pm. Hope you guys enjoy my family's suffering :).

The two images were taken 14 hours apart on the Tukino Ski Field access road. This is almost in the middle of the north island of New Zealand, just south of Mt Ruapehu. The night photo was taken last night during my second ever session of Astrophotography. I wasn't thinking about this contest when taking it, it was simply that my wife pointed at the two lights on the Tukino Ski Field (the Lodge and mechanical buildings I assume) and asked me to take a picture of the mountain with the stars above visible in frame. When I was finished we drove to Taupo (about an hour north following the number 1 highway), and stayed the night in a Lodge with Mineral Spas in the guest rooms – very nice and a must for any cold and weary photographer! We checked out around 8am and started our four hour drive back to Wellington.
While driving back this morning we stopped at the same place and found the holes created by the tripod legs were still visible from the night before in the course volcanic sand. I set up the tripod in the same place and took several 'day' pictures at the same angles/directions as the photos I had been taking last night simply for comparison. When reading Gizmodo this afternoon my wife pointed out the competition and suggested I take my night and day photos of the ski field and 'make something with them'.


The camera?
Canon EOS 5D MkII (my 'baby'). I've had her for about 5 months. I purchased her after spending about two years learning the basics my old Canon EOS 1000D.
The Lens?
Canon EF 24-105mm 1:4 L IS USM. My normal 'playing around' lens. (I know there are lots of better lenses, but I figure if I can't make reasonable shots on the one that came with the body, then it is me who failed, not the fact that some others might consider the lens as not the best one I could be using)
The lens was set at 60mm.
The day shot was an ISO2000 f22 at 1/2000
The night shot was at f4.0 for 25 seconds

I'm moving out of my apartment this weekend so I'm glad I got this opportunity. It's too hazy in Dubai during summer to include much daylight. Nevertheless, I went to the roof of my building on Friday and took my day shot. Someone moved my markers (coins-duh!) but I managed to get the approximate position and adjusted in Photoshop.

I finally broke down and spent the money for a DSLR and was really excited to participate in the next photo challenge. I was even more excited when I found out that the subject was day to night because I knew the perfect location for such an endeavor: a restaurant called Cha Cha Coconuts on the roof of The Pier in downtown St Petersburg, FL. They have an amazing view no matter which direction you look and tables set up against the railings that make it the perfect spot for setting up a shot like this one. I went with some family and friends and we ate, drank, and had lots of fun toying around with the shot possibilities. Merging the two photos using gimp was tedious to say the least, but I think the end result was worth it!

I've taken so many pics from my parents' balcony that looks out at the bay. I was a little worried because the amazing sunrises are during the winter and we've had a lot of fog over the past week that is so dense you can barely see the trees. I woke up at sunrise and that was very much a failed attempt. The sky was blah and then the fog rushed in. The sun came out for a couple hours and that's when I got my day time pic. Unfortunately, the sunset left a lot to be desired but night time was actually clear across the bay. It was quite a yo-yo, however I did learn some new things which I'm quite psyched about.

I took this picture from my balcony. This was the best vantage point I could get. I live on the 3rd floor in a flat block. I set up my tripod in the balcony, decided on the frame and took 1 picture and marked the placement of legs of tripod with a chalk. So whenever I had to take the picture, I would put the tripod at the marked place, set up the camera and take the picture. I took multiple pictures of different times but in the end I liked the contrast in the pictures taken in afternoon and the night. I used Photoshop to blend the pictures using gradient tool.

I think I'll call this photo "Streelight People" in honor of one of my favorite bands. In any case, this photo was taken on the third story of a parking garage behind the local theater, once at 3PM and once at 10PM. I actually took around 20 photos each time and made a mild HDR effect from them to enhance the contrast and saturation and the camera was a Canon T1i using the kit 18-55mm on a tripod. I actually had a lot of fun with this challenge and it forced me to learn something new about editing photos as before this I didn't know how to merge shots like this.

I have been seeing these photo challenges on Gizmodo for quite some time now, but never had the motivation to try one out. Call it what you will, but I blame laziness. While reading a post on, one of the commenters mentioned that there was another Gizmodo shooting challenge up. I figured eh, what the hell, i'll give it a go this time. I have taken a lot of night shots of the city in the past, but wanted to try something a little bit different. So on one of my fishing trips I hauled the camera down to the river, took aim and fired. For those wondering, I caught no fish and received a nice speeding ticket on the way home. But, all in all a pretty good night.

I recently came across this site last week and crazy to apply the technique after it was announced. Leant about the technique and found very interesting. I searched for similar photos in flickr and google However all the photos I saw had dradient applied either vertically or horizontally. I thought of applying the gradiaent diagonally to show the transition from night to day.

I was at the fair this past Saturday and was helping out a friend shoot some unrelated pictures in his horror-clown getup. We got a later than expected start, so while he was changing clothes I noticed the big... well admittedly small... Ferris wheel in the distance. I had my D7000 and a kit lens on for the shoot, but had also brought my tripod with me. I thought about the photo challenge in the fleeting light and quickly set up a tripod to capture the day picture.
Using a black spot on the tarmac (hey - better than chewing gum!), I set up the night shot when we were done scaring folks for for the night and clicked the pic wrapping up.

I've been wanting to take some pictures of this brand new wind farm about a half hour from home and this seemed the perfect opportunity to do something different. I took the day shot around 10:30 AM and returned that night around 8:00 PM. Amazingly this just happened to be the time a storm was passing though about 20 miles to the north and I was lucky enough to capture some nice lightning bolts. They seem to add a nice symmetry with the amazing power of nature on one side and our attempt to harness it on the other. I used a gradient mask in Photoshop to blend the two together and corrected the color of the lightning a little since it tends to be a little too purple. Other than that and a little boost to clarity in Lightroom I didn't have to do any adjustments to the raw files.

The Oasis Lake Travis Austin

Shooting summary: Canon T2i, kit lens, iso 100, 1sec
Went on a family weekend trip to Austin's Lake Travis where The Oasis restaurant is located, took the picture from a clear bottom observation deck (not good for my fear of heights)
While trying my hardest not to have a panic attack I set my camera on a small ledge because I didn't have my tripod and took this one shot of what I thought represented day to night in Austin. People out having fun on boats swimming in the cool waters of Lake Travis to groups of hungry people gathered around a dinner table enjoying delicious Mexican food.

-Thomas Salazar

Finally found inspiration for one of these shooting challenges! We rented a house in cape cod that had a deck with a view that seemed perfect for this challenge. Forgetting my tripod, I set my Canon T2i up on an extremely flimsy plastic stool. I placed a thick book on there as well in hopes that the constant 10+ mph winds did not knock the camera out of position over the 3+ hours I was shooting. It actually stayed pretty still but still needed aligning due to the stool shaking when pressing the shutter.

Two walks across town, counting pavement stones to shoot from *exactly* the same spot and "hunting" for driving by cars - this was definitely a lot of fun :)!
Pictured: a Renauzda (part Renault, part Mazda) driving out of the night, on "Plac Dąbrowskiego" in Łódź. I took over 30 shots at night and 50 shots the next day to be sure that there will be a matching pair of cars. A rear-curtain flash made the back end of the black car visible at the end of the trail of it's lights.

A good friend of mine was dog sitting in a 58th floor condo in downtown Chicago and when she showed me the view from the balcony, I thought of this shooting challenge. I took a few pictures of the city at night and decided to use the view of Millennium Park, Lake Shore Drive, and the rest of the city for the challenge. The next morning I took pictures from the same spot. Then I merged them in Photoshop with a gradient mask.

I knew I wanted a shot of Church Street Station from day to night. I was shooting from the 4th floor on the opposite side of the train tracks. This is the tiny portion of Church St. between the tracks and I-4. I love how a shop can go from no there in the day to crowded full of patrons at night. I hope you enjoy it as much I as I do.

The shot is of Canary Wharf from the south side of the docks. This shot is composed of 2 HDR shots, created using 6 individual shots each with one exposure comp stop processed in PhotoMatrix Pro. I then used GIMP to merge the two images to create the day and night shot.
This is my first day and night shot. I am old school so I like to do things manually sometimes not out of choice. I rigged up my tri-pod cracked open a couple of beers and let three hours pass and created this beauty.

Finally my first submission, this one seamed very Interesting challenge so I gave it a try. This is the sky line from our apartment in Coral Gables, FL. The shot was taken at 8am and about three hours after sunset. Unfortunately, I didn't have the tripod with me so all shots were handheld. Nothing super special was done in post production other than some simple RAW adjustments. Taken with Nikon D90, 50mm 1.8

Time was closing for this weeks challenge and I couldn't think of anything. After a long night of playing WoW, I went outside to let the dogs out and that is when I wondered what the inside of the car would look like in the two lights and this is what I got. Not my best work but found it a little interesting. Shot with Canon T1i, 18-55mm lens.

I was on a work trip, sitting out late together with a colleague and a couple of beers at the University of Jyvaskula/Finland, when we looked up at the arcs of the bridge connecting the institutes. Looked like a great shot. So I took a couple, putting the camera on the floor pointing upwards.
Varied F-stop and ISO settings and used mostly autotimer. Chose the position of the camera so that some characteristic stones on the floor were adjacent. Next noon, took the day shots at ISO 400 with autotimer and was worried because no sun came out. Now I think it was great - the grey rainy sky gave this composition its space-station-like look, I liked best.
All postprocessing done in GIMP - essentially only shot-matching & transparent gradient overlay.

When I read this week's contest I pretty much knew right away that I wanted to use the "L" in it. Fortunately my girlfriend's balcony overlooks the Racine stop and the Eisenhower. I strapped my Ultra-pod to the railing and took a longer exposure at night. There was rain predicted so I couldn't leave the camera out all night so when I snapped the morning pic it was slightly off. Oh, and the car in the very bottom corner had moved. So there was some ghosting I had to work on, but I was pretty pleased with the final result of the train and the cars.

I decided to try capturing the "John Nolan Drive" in Madison, WI transitioning through day to night. I love this scenic drive along the lake and this challenge gave me the chance to see how it would look if a car on this drive were to progress from day to night (rather quickly). Yesterday it was a beautiful night with the moon shining down and reflecting on the lake, which made for a beautiful night photograph. This afternoon was quite sunny; giving me the chance to capture both occasions. It was quite a challenge to get the same exact image from the same exact location twice, but it worked out!

I used a Nikon D90 with the kit lens and just the auto/no-flash settings. When I went to Las Vegas this weekend my wife and I got upgraded to the 16th Floor of the Flamingo during our first night. I saw the awesome view and had to take a couple of pictures. The next morning I took another couple of shots and realized that this was kind of what the Shooting Challenge was this week. The strange doubling from the Cesars and Planet Hollywood signs comes from the fact that I was shooting through double paned glass at an angle. I thought it gave the picture a kind of cool "The Hangover" look. If you're curious, no the Flamingo isn't "pager friendly".

-John Vodopija

I decided to do a day to night photo in my living room. There's very big windows and during the afternoon hours, it receives a rather awesome amount of sunlight from the setting sun. With that in mind, I capture one window in the full brunt of the afternoon sun (about 2 PM) and then the other window is in pitch black (around 8:30 PM). To acheive a logical balance, I tried to clip what the daylit room looked like in the nighttime window. It's why one of the identical floor lamps in the room is dark brown in front of the window and brightly yellow beyond that window.

-Cory Newkirk

Best laid plans of mice and men. I thought this challenge would be cool if I would be so lucky as to get lightning in my night time shots. But Mother Nature decided not to play ball, in more ways than one. With intermittent showers and clouds, plus some travel requirements of the long weekend limited my opportunities for shooting. In ended up just looking at a portion of my front yard where there are some solar lights. I took three photos with my Canon EOS Rebel T2i rotated 90 degrees to create a panorama of vertically oriented images. I took three images with an f stop of 7.1 and an ISO of 1600, and various exposures (1/50th sec, 8 seconds and 3.2 seconds) just before, during and after sunset. My tripod was set up so that two of the feet were in the joint of the concrete and I simpley detatched the camera between shots. It is no means as good as the demo photo, and this process seems better suited for multi-shot panoramas (5 or more) but at least I tried.

-John Hays

I used my 60d with the stock lens in downtown Fort Myers, FL. The day light photo consisted of the amber and red light while the night time was green with the walk sign. I mixed between day and night on the lights as well as the walk/don't walk box. Both photos had an exposure time of 0"3 and an iso of 100.

I went camping with Ustadza for Labor Day weekend. I know AZ pretty well, but we decided to head out to an area I don't know so well, which turned out to be an amazingly beautiful Coloradoesque landscape. We were equipped for car camping only, having a heavy canvas sleeping bag, Kelly Kettle, and jars of food rather then dehydrated stuffs. Despite this, I had brought along my black hole of backpacks (5500ci) so we managed to smash, cram, squish, and strap everything in place and make the short 1/4mi walk down to the lake where we found the perfect rock camping pad. Keeping this contest in mind, I set up the camera on the tripod right before bed. For the night shot I used ISO 640, 16mm, f3.5, and 2min exposure. I had Ustadza in the tent with a little LED lantern which she turned off after the first 10 seconds. After a good nights sleep I got up just after sunrise, put the camera back on the tripod which I had left in place over night, and took the day shot at ISO 640, 16mm, and f5.6. I can't give a shutter speed as the day portion is actually an HDR of 3 photo's. I'v had the great fortune to be able to camp all over the world, in many exotic places, but this has to be one of my top 10 favorite places to camp.

I had spent the better part of an hour trying to decide whether or not to go with a horizontal or a vertical gradient for this shot, when the song "Where Is My Mind" by the Pixies got stuck in my head. "With your feet in the air and your head on the ground..." Those words pretty much describe how I see this picture. Taken from
the 20th floor of an apartment building in Crystal City, Virginia, with the help of a new Sigma 10mm Fisheye lens. Day: 1/80 exposure at f/8 and iso 100. Night: 6" exposure at f/4.5 and iso 100.

I took this photograph from the Top O Topanga Overlook which has a great view of the San Fernando Valley. The greatest challenge I faced was dealing with the broken swivel lock on my tripod. I couldn't get it to sit still so the images weren't aligned. Fortunately I was able to realign them in Photoshop. For the final image I used gradient masks to blend five separate images together. Four of those images were HDR images so technically it took 13 shots to get this final picture. I should also note that this was my first time using Photoshop so it was quite a learning experience! Canon Rebel XT, Canon 18mm, F11, various shutter speeds, ISO 200.

Instead of a birthday party, my son wanted to stay a night at the Hilton Hawaiian Village. When the front desk person found out the stay was a present for my 8 year-old-son, she gave us a room with one of the best views, and I left my good camera at home. I just had my pocket camera. I have followed the Gizmodo challenge, but never entered. This intrigued me as I want to update my Photoshop skills. The sunset was beautiful, the night view breath taking, but the combination is awesome. I'll be making a print of this one.
The photos were shot with an Olympus Stylus Tough.

So let me first start off with…"it's like wicked dahk down there, you can't see a thing - how's it going, Bob?"(Nemo) When I took these photos the other day it was extremely windy!!! Windy like, awesome, sand particles + electronics= Uh oh divided by particles in the eyes with a remainder of "wait that's sand in my mouth"(beach was behind me). Anyways, this is my beautiful home, Chicago. Let's get to photo settings shall we? Everything was shot with a Canon 40D with a mid range 35-155mm Canon lens. The day image was shot at a 1/50 sec, F/22 and ISO of 320. Night shot at 6 sec. exposure, F/22 and ISO at 640. The edit was just a basic overlay, with a vignette and about a +8ish saturation. I hope you enjoy the photo because it was a blast to shoot!

-Nick Duel

These photos were taken from my balcony in Oxford, England. I am fortunate (or unfortunate) enough to have a pub on my street, The Star, which I've always thought looked sort of charming at night, but I have to admit my real motivation for photographing my street was convenience :) I used a gorillapod attached to my balcony railing, which was great because I could just leave it there until the next day. The images were blended in photoshop using a gradient pixel mask to gradually fade the daytime image on top of the nighttime image background. I only faded the daytime image enough so that the lights from The Star came through. It looks a bit like a storm is coming in with clouds dark enough to trigger the street lights.

Shooting early this morning around sunrise, I decided to take part in this challenge. Since it was raining, I was stuck in my apartment so I shot this lamp post outside on the street. I used a few blurs on the gradient mask, and was happy with the effect, but I'm definitely going to have to do this technique in a better location!
