Make it Stop in Stereo

View Assignment Details

One of my favorite scenes in the Twilight Zone episode ”The Invaders” is when Agnes Moorehead freaks out at the high pitched noise from the flying saucer. I played on this scene a bit in my with my comic effect assignment “Make it stop.” I figured I would experiment with this using the “Wiggle Stereoscopy” assignment. The cool thing about this assignment is it’s two shots animated that really give the illusion of three dimensions. So neat! What’s more, it’s a fairly easy process once you know how to make a GIF. Just pick two shots and have them animate alternatively.

That Wiggly Old Monk

View Assignment Details

A Wiggle Spectroscopy ds106 assignment:

Take two photos of the same subject from slightly different angles. Merge the two photos into a single looped, animated gif to create a wiggle stereoscopic image that simulates 3-D. A very good tutorial explaining the full process can be found on Martin Sutherland’s website.

I did not even intend to create this, but I took two photos in succession with my iPhone, and there was enough difference of angle (and the motion of my new friend Amyaz moving behind the bottle), to make it work as a wiggler. I used the PhotoShop Script “Load Files into Stack” and then simple GIFfed them out at a 0.2 second frame rate.

It almost suggests the frenetic influence of rare rum from India? Perhaps.

The back story…

It was almost an accidental choice when I booked a room for two nights at the Black Squirrel Inn www.blacksquirrelinn.com/ here in Wooster, Ohio.

What a treat to meet such a nice person as my host, Fong, but then it turns out her husband, Amyaz, is a Wooster prof and was in my worksop Tuesday! We hit it off, and he stopped by tonight to share more stories and rare rim from India= apparently Old Monk is not available in the US.

Old Monk is a vatted Indian dark Rum, launched in 1954.[1] It is blended and aged for a minimum of 7 years. It is a dark rum with a distinct vanilla flavour, with an alcohol content of 40%. It is produced in Ghaziabad, Uttar Pradesh, available in all parts of India.

There is no advertising, its popularity depends on word of mouth and loyalty of customers. Old Monk is the largest selling dark rum in the world Old Monk has been the biggest Indian Made Foreign Liquor (IMFL) brand for many years.

Here is to serendipity and connections.

And [wiggly] rum.

Wiggle Stereogram

View Assignment Details

I mentioned last night that I’m going to work along with UMW’s summer DS106 section beginning next Monday. In order to get ready, I’m cracking my GIF knuckles and getting my workflow down so I can spend more brain power on problem solving rather than just doing the work.

I went through the DS106 Assignment Bank, looking for something that would catch my eye. I came across the Wiggle Setereoscopy assignment. Mostly because it had a hilarious name, I took a look at it and tried it out.

I didn’t want to use an app to make the stereogram, because I felt like that would be cheating somehow. I wanted to take my own pictures and then use GIMP to make it dance. My first two attempts were terrible because my photos were too far apart. I learned after trying twice that the camera difference needs to be very small. Much smaller than you would assume…and that was the hardest part of the assignment.

I took a two photos of my AT2020 USB mic sitting on my bookshelf and then opened them as layers in GIMP.

The first thing I did was crop the photo down to a manageable size. With the original at over 3000px wide, it was a little overwhelming. The final version is 700px wide.

I really wanted to do something like Alan’s, where the object was nearly stationary in the middle. I dropped the opacity on the top layer and tried to line it up as best I could, but because of the way I moved the camera when I took the photo, there’s still a little wiggle.

Then, it was just a matter of bringing the opacity back up, tweaking the frame rate (I ended up with 75ms per frame), optimizing for a GIF, and exporting the file. All in all, it took me about 20 minutes to do (minus all the photography trial and error from throughout the day) and I’m pretty happy with the result.

Dance away, AT.

this is the first Wiggle Stereoscopy I made for the ds106 wiggle stereoscopy assignment. I used two photos of her from my mother’s camera, she is almost 11 month old now, still survives on formula!

I created this example Wiggle Stereoscope for class today. Below is a tutorial about how to make a Wiggle Stereoscopic image (ok this isn’t really a stereoscope image just a two frame animated GIF, but the technique is the same) and how to post your first Visual Assignment to DS106.

Two Quick Wigglers

View Assignment Details

I thought it was time to try the ds106 Wiggler Spectroscopy assignment:

Take two photos of the same subject from slightly different angles. Merge the two photos into a single looped, animated gif to create a wiggle stereoscopic image that simulates 3-D.

I decided to use my pal Spike, the metal dog in my front yard, taking about 4 pairs of photos. As ti turned out, my angle of different between each pair was a bit too much, but some of the ones that were similar in angle had enough different to make it interesting:

and from the other side…

I made mine in Photoshop by using the File -> Scripts -> Import into Stacks command, using the option to align objects- this has the effect of keeping Spike mostly motionless but animating the background.

Usually I have to do some futzing back and forth from the timeline view to the frames view in the Animation window. I select all the icons and set the animation speed to the quickest option (0.1s), Keeping the size at 500pixels wide, and 64 colors for the GIF options kept the files small (under 300k each).

Wiggling is fun! Spike is just happy to wiggle all day because…. what else is there to do?

I have been dying to do the Wiggly Stereoscopy assignment by Bill Genereux—it basically uses the animated GIF method to create a 3D effect with just two images. It sounds easier than it really is—nailing it is all in the images you choose—though I must say Norm makes it look easy. Once I had two images I believed would work I wanted to see if I could find some useful tips from folks in ds106 who already did the assignment. Turns out I could, Katie Girard wrote this helpful post that introduced me to the animation filter in GIMP, something I knew nothing about.

Not only can you use the Animation filter to view the image moving through the layers, but you can also change the speed using this helpful tidbit from Katie:

….under Filters > Animation, I chose Playback….you can see your .gif in action as it rotates between layers. To change the delay between the two frames, select the layer and add a time written in milliseconds using this format: [imagename (nms)] where n = the number of milliseconds. I chose to use 750ms.

The default speed worked well for my stereoscopy, but here is a more specific tutorial for changing the speed at which layers switch in GIMP for anyone interested.

One thing this reinforces for me is how amazing the ds106 assignments repository is. It not only has a ton of great assignments but lists everyone who has done that assignment. Sure some links to example posts will break in time, but the bottom line is it gives other people thinking about what to do ideas, inspiration and even helps them learn some technical details they might not have known otherwise. As time goes on I’m convinced we’ll see more and more tutorials in the assignment repository as well, and to that end this post is the change I want to see
