In the previous parts of this series I looked at ways of creating anaglyphs with Photoshop, both from old stereoscopic images and from a set of two images shot with a hand held camera. But what if you’ve already got a photograph and want to “fake” a 3D image? Well, I think I’ve worked out a method of doing that, too.
So far I haven’t found any tutorials online for creating fake anaglyphs in Photoshop. I did find Jim Long, who has done an excellent job of converting 2D images into 3D cyan-red anaglyphs. Jim as quite the gallery not just photographs, but also of classical art rendered both as stereoscopic images and as anaglyphs. Here’s his version of Da Vinci’s Mona Lisa:
I don’t know what process Jim is using, but he manages to maintain color on the images very well. He also has a link to a supplier of 3D glasses with one of the most extensive inventories I’ve seen. Continue reading “Fun with Anaglyphs – Part 4”
In my last post I talked about discovering that the South Carolina Digital Library has a new collection of 3D images. They have taken old stereographs from the Civil War era and have converted them to anaglyphs so that they can be viewed using 3D glasses. As I was thinking about how they did this, … Continue reading Fun with Anaglyphs – Part 2
The past several posts I’ve been singing the praises of Google. However, all is not perfect in Google Land. There have been the occasional really bad ideas – Google Wave, for example – and the abandonment of some really good ideas, such as Google Notebook. In this post I’m going to stay away from the more published flaws that Google has had to endure. Instead, I’ll cover just a few things that I’ve found to be a bother.
I’ve already mentioned that until only recently, group accounts could not be used for Google Maps, Picasa, or other many other Google products. That really limited the effectiveness of those accounts. Fortunately, that has been corrected. However, there are still a few things that are not quite right. Continue reading “A Few Google Flaws”
As I mentioned in my last post, I’m encouraging our teachers to use Google Docs with their classrooms through our new Spart5.info domain. Our district, like most in the state, has standardized on Microsoft Office. We have no intention of changing our basic productivity platform. I think of Google Docs as a complement to, rather than competitor to Microsoft Office.
I’ve been using Google Docs personally for a couple of years now. The convenience of cloud computing was just becoming apparent, and I liked the idea of having my work available on any computer I happened to use, as long as it was online. I first tried it in earnest with an online course I was taking for recertification. It just seemed like a good place to keep everything together.
I’m using Google Docs more and more now, but most often I use it for documents that I need to find quickly – reference documents such as my resume, circuit ID numbers, etc. I also use it for keeping notes at various meetings because it’s so easy to share the notes.
I’ve got a little Dell netbook that I use all the time (I’m using it to type this right now.) Unfortunately, it’s a first-generation netbook with limited processing power and only a 16 GB solid state hard drive. I just don’t have room for MS-Office, so I rely on Google Docs and the ability to be online just about anywhere. Continue reading “Google Docs Rundown”
While in Washington State last week I didn’t have good Internet access. Laura’s mom still uses AOL dial-up. Neighbor Duff offered access to his WiFi, but we were just out of range. So this was the perfect chance to try tethering my laptop to my HTC Android phone. It worked brilliantly!
I had explored several options for phone tethering. The current crop of broadband modems just seemed like an additional expense for something with limited capabilities. I had almost bought the Palm Pre, which can set itself as a WiFi hub, before settling on my HTC Incredible.
I knew I didn’t want to do anything crazy that involved root access to the phone. I needed something fairly simple, so I first tried PDANet. I’d had some success using the free version connecting to my netbook. However, it was very buggy and kept wanting to crash when I tried connecting it to my larger laptop.
I finally settled on EasyTether, and it worked like a charm. The phone connected to the laptop with no problem, and I was even able to access the drive space on the phone over the USB cable – something that I couldn’t do with PDANet. I wound up purchasing the full version of the program for under $10, which gave me access to https and secure sites. With that I was able to check GMail and remotely log into my district’s network to do some simple maintenance.
I’ve read that 3G speeds are nowhere near as fast as cable or DSL speeds. However, the speeds I got over my phone were pretty darn fast. I didn’t try watching lots of video, but I did see a couple of clips, and they played just fine. I also uploaded lots of high resolution images to Flickr, and those went without a hitch fairly quickly. As far as I could see, there was nothing I couldn’t access that I would normally access from my home Internet connection. Continue reading “Bring Your Own Bandwidth”
I had an eye-opening discovery this week. One of our principals contacted me about an e-mail she was expecting that hadn’t arrived. I went into our district spam filter to see if it had been caught there. While looking for the e-mail, I noticed a lot of traffic from Facebook that had gotten caught in … Continue reading Facebook and Professional Boundaries
One of the reasons I upgraded to an Android phone was my interest in Augmented Reality. I knew I would be doing some traveling this summer and wanted a way to check out items around me quickly, without having to bring my work Blackberry along. I got a chance to put the new smartphone through its paces last weekend in Washington DC, and here are some of my initial feelings about AR…

The problems surrounding teachers using Facebook seem to be getting more and more complex. I’ve written before about how teacher’s private use of Facebook can impact their jobs, whether justly or unjustly. The issue that was brought up recently involves teachers’ use of Facebook on private mobile devices during school hours.
This is a tricky issue. We want teachers to be doing what they are paid to do – teach their classes and monitor their students. But how do you keep this in check?
We have Facebook blocked in our district because of some of the discipline issues is creates with students. It was suggested that we consider adding restrictions on Facebook usage on private mobile devices to our Acceptable Use Policy. I flatly disagreed with that. Our AUP regulates acceptable use of district-owned equipment and services, not private equipment. I don’t think should or legally could use a policy written for district equipment to be applied to private equipment. Continue reading “Facebook and Online Responsibility”
I’ve been accused of having too many gadgets. I confess, I have quite a few. However, I’m not one to rush out and buy the latest just because it’s new. I need to have a purpose for the gadgets that I get – not just so I can have something shiny. Yesterday, however, I met … Continue reading The Tech Guru
Google’s at it again with another product that everyone wants. This time it makes more sense than Buzz or Wave. Google is looking for a community to serve as a test bed for its 1 gigabit fiber optic Internet connection, and Greenville wants it. Of course, so do several other cities. Topeka, Kansas notoriously renamed … Continue reading Vote Greenville for Google Fiber!
