This is a camera. The Lytro camera lets you create living pictures that you can endlessly refocus after you take them.
The last time someone photographed you with a Sun 660 Autofocus camera, you were four years old and wearing a visor, jogging shorts, and knee-high tube socks. These carefully refurbished vintage Polaroid cameras and meticulously reformulated instant photo film from our friends at the Impossible Project bring us back to those days of pre-digital bliss. In 2008, the Impossible Project saved the last Polaroid instant film production plant from extinction and set out to reinvent and reformulate instant photo film. Thanks to them, it’s now easy to create beautiful, tangible analog photos of those moments we all want to preserve with a timeless look and feel.
Welcome to a world where photography isn’t about the megapixel count, the size of the sensor, or a zoom so powerful that you can snap a blurry picture of Saturn. The Sun & Cloud is a lo-fi camera that is ultra simple and philosophically pure: it’s all about “letting go” and embracing the idea that great photos aren’t always about technical supremacy. It’s like a sketchbook for simple and creative images. Hailing from Japan, the beautifully-designed and notably square camera is powered by solar panels and a hand-crank, keeping you snapping without ever having to think about anything other than your next shot.
The Sigma DP3 Merrill looks down at most other compacts with a serious sensor, in this case the same Foveon X3 system from their high-end (see: $3,300) DSLR line. It packs a stunning 46 megapixels into a compact body that is mated to a very fine 50mm f 2.8 lens. That’s a professional-grade image sensor and a professional-standard lens in a small, pocket-sized form factor.
This little scoop of a camera is totally adorable. Solar-powered. 3-megapixel CMOS sensor. AND built-in LED for shooting at night.
Parties are awesome. You bring together good people with good music and some booze and you (sometimes) have yourself an great time. But everyone knows that some parties are better than others, and there are definitely ways to turn a decent party into a great one. We challenged ourselves, twice, to create an amazing party using online/offline social technology. And so begins the story of Grand St.’s attempt at party hacking.
After brainstorming a bit on what we could do to up our party game, we decided a photobooth would be the way to go. We didn’t have an extra $3,000 lying around to rent a booth, so we decided to just do it better ourselves. Hack the system and what not.
But this wouldn’t just be a regular photobooth - it’s quite easy to find information on doing that. Our goal instead was to make something better, something that took advantage of the incredible social tools available today, and combine it with an old fashioned photo booth to provide a more interactive and engaging experience (translation: more awesomeness —> better party).
First, we had to construct a booth that took amazing photos.
Second, we needed a sharing mechanism. For this, we decided to use a very under-celebrated feature of Google+ called Party Mode, released last year at Google I/O 2012. Party Mode is a real gem — it gives everyone the ability to share photos with the entire party in real-time. It also allowed us to show a live stream of the incoming photos on screens throughout the apartment.
Third, we wanted to print strips of photos for people to take home.
Finally, speed. The shoot/upload/share/print sequence had to happen as quickly as possible.
CONSTRUCTING THE BOOTH
It all comes down to the space you are working with, and the amount and quality of light available. Honestly, you could pull this off with the camera on your phone and a creative light source, but we wanted to be able to provide people with photos that would look amazing printed out or viewed later online.
We went with an open standing booth, though there’s much room for variation with backgrounds and setup. The camera sat on a tripod and was secured with twine to the AV unit it stood on, and the tripod legs were then wrapped with a black tablecloth. An outline on the floor made with bright blue painters tape showed people where to stand without getting in the way. To trigger the camera, we mounted a wireless RF button to the wall by the standing area so that the booth could be self-service.
We selected a lens (for our camera it was a 50mm prime) that provided enough field of view for around eight crammed people standing. Using a particularly fast lens isn’t needed or beneficial as you’ll likely need to stop down to ensure adequate depth of field, and the flash is providing most of the illumination anyway. f4 seemed to provide enough depth with a nice slight blur of subjects far out of the focal plane and a shutter speed of 1/125 second was decently fast enough to freeze people moving around in the frame. The flash is going to be stopping the motion anyway.
We were lucky to have a somewhat controlled environment where lighting wouldn’t vary much throughout the party. Everything should be set to full manual (shutter, aperture, focus, flash, iso, and white balance) if the environment allows for it. If lighting is going to vary, then the only auto-exposure technique that should be really considered would be the flash’s TTL mode with everything else set to manual to keep shots looking as consistent as possible.
An external flash is mandatory for a photo booth, and getting the right effect will take some trial and error. We found that the speedlight mounted on the camera and bounced off the white ceiling to provide nice soft lighting with minimal shadows. Just make sure you have lots of AA batteries available, as the flash is going to get quite a workout.
When in Party Mode, any picture that you take on Android or iPhone* gets automatically posted and shared to Google+. We wanted to make sure every photo we took was immediately accessible, but auto-sharing to Google+ posed a serious problem as Google+ Events does not have any publicly exposed APIs.
We started to try to solve this by writing an Android program that pulled images from an FTP server and adding them to the Android photo gallery, but this wasn’t to our satisfaction.
In doing it though, we noticed that for each event that we created and uploaded an image to also created a Picasa album which has a very simple API. After some testing it then became apparent that these simple lines of code would upload images to a Google+ Event:
URL albumPostUrl = new URL(“https://picasaweb.google.com/data/feed/api/user/” + ConfigHolder.config.google.userId + “/albumid/” + pg.galleryId);
PhotoEntry myPhoto = new PhotoEntry();
myPhoto.setTitle(new PlainTextConstruct(” + ConfigHolder.config.google.imageTitle));
myPhoto.setDescription(new PlainTextConstruct(” + ConfigHolder.config.google.imageDescription));
myPhoto.setClient(” + ConfigHolder.config.google.clientName);
MediaFileSource myMedia = new MediaFileSource(pushToGoogle, “image/jpeg”);
PhotoEntry returnedPhoto = myService.insert(albumPostUrl, myPhoto);
Sweet, we could now automate the uploading of images to our Google+ Event.
We then built a very simple program that simulated the experience of a photo booth. Here is the outline of how it works:
- Camera remote release would be pushed and would trigger 4 shots. The first shot was delayed 5 seconds, and the remaining three shots had 2 second delays.
- Jpegs (9MP Fine Quality) would be automatically sent from the camera to a computer directory via USB using a camera tethering application or via an Eye-Fi card.
- Every 10 seconds the programs check to see if there are 4 files in the directory
- If there are 4 files, grab and move them so we don’t pick them up on the next pass
- When the program grabs the 4 files, it would then:
— Create a Square Photo for Uploading (2x2)
— Create a Strip for Printing (4x1)
— Add branding/backgrounds to each of these
— Save the files
— Upload Square (2x2) to Google+ Events
— Print Strip (4x1)
The code is written in Groovy & Java using the Grails framework. The Grails framework, much like Ruby on Rails, is a quick and dirty way to get a lot done in a very short amount of time. We built a simple web interface to allow you to pick the album you want to upload to and a simple page that refreshes every 30 seconds and always shows the last finalized photobooth image.
For the New Year’s party we actually modified the code and added a second camera that was roaming around the party and by using the Eye-Fi, any picture taken at the party with that camera was uploaded to the event instantaneously.
Here’s a link to the code, which we open-sourced: https://github.com/aaronhenshaw/photobooth-party
THE PRINTING AND DISPLAY
We then set about creating the printing experience. This was pretty straightforward - it took a bit of adjustment with the resolution and printer settings but we were able to rig it up with some gloss paper pre-cut into strips and a regular photo printer.
We then had 2 screens placed throughout the apartment that was rotating the real time feed of all the photos taken at the party (both photo booth and phone pics). It was great to be able to see what else was happening or who else was at the party at different times and places over the course of the night.
RESULTS AND SPEED
If you google “custom photobooth”, there are a ton of options for making photobooths, but nothing we found where photos could be shot, uploaded, shared, printed and downloaded in about a minute. We believed that the timing was just as important as picture quality or uploading to Google+, so we spent the time necessary to shave off seconds wherever we could.
Overall, we created and uploaded 212 photo booth images across the evening for our first party. The party started around 11 and it ended at 4 (We did this again for our new years party and we got even more pictures — 254 photo booth images across the evening). With over 5 hours of party, that’s a new set of photos every 90 seconds.
For us, the project was a huge success. People were amazed at how seamless everything worked and had a great time at the party.
…and the photos look amazing.
We open sourced the code and wrote this blog post so that others could do what we did. Here at Grand St. we are all about hacking together things to create better experiences and improve your life.
