Four for Friday, November 30
I hope everyone had a lovely Thanksgiving holiday and didn’t go too nuts on Black Friday (I’m sad to say that I did go a little off the deep end). Anyway, to keep you sane before the weekend officially arrives at 5 o’clock, here are four interesting links I stumbled across this week.
- Tilt-shift photography: For real vs. faking it
I always loved this particular photographic effect but I didn’t know that the technique had a name. You can achieve a similar effect very easily in Photoshop, but for the real deal, you have to have a tilt-shift lens (such as the PC Micro-NIKKOR 85mm f/2.8D lens if you’re a Nikon user like me) or a Lensbaby, which looks to be a fair compromise. - Tech toys for the preschool set
I think it’s not unreasonable for me to be alarmed at the trend towards putting children in front of screens at a younger and younger age; a number of organizations, including the American Academy of Pediatrics, recommends that children under two years old not watch television at all, and that older children be restricted to one to two hours of screen time per day. (In fact I wish I could reduce my screen time to one to two hours a day, but that’s difficult to do in almost any job nowadays.) But the trend this year seems to be towards “tech toys” that actually work. What does this mean? It’s hard to say right now, but in fifteen to twenty years perhaps we’ll be able to tell how the introduction of technology at such a young age has affected the new generation of kids. I genuinely hope that my fears are unfounded. - Bad product design
This link is a little jokey, but it points out something valid–products can be so badly designed as to be utterly ridiculous, bordering on useless. It may be true that all of the items presented in this collection (taken, by the way, from the SkyMall catalog that you’ll find on virtually any airplane in the United States) may be able to do what they were designed to do, but at a certain point you run into the problem of the law of diminishing returns. To paraphrase in this instance, cramming multiple features into one device reduces the overall usability of the device to the point where it’s so unwieldy to use that it becomes practically useless. - Hijacking a television signal
On November 22, 1987, someone wearing a Max Headroom mask managed to twice interrupt the signals of Chicago-area television station, and no one has ever figured out who it was or what the motive was. A fascinating look back at television history, especially when you consider how difficult it would be to hijack a digital signal these days.
