5 Minutes with a 500mm Mirror Lens

My Pentax K200D with a 500mm Samyang mirror lens attached
Last year when I went to India I enlisted the aid of a cousin who was coming in from the States to bring me a bunch of photo equipment -- most of which I subsequently never used, except for the M42 mount adapter ring that allowed me to use my old 58mm manual F2 Zenit lens on my Pentax K200D digital SLR.

Because the Zenit has sat on my camera for the past six months (I love it!), I have not really given much thought to using the other lens I got, a 500mm mirror lens. Mirror lenses are odd beasts, behaving like reflector telescopes rather than straightforward lenses. The upshot is they're a shorter size for more zoom, and give you odd donut shaped bokeh.

Choosing the Right Camera Travel Bag


Any photographer, be they professional or photo-enthusiast, will tell you that taking care of your equipment is one of the major concerns of the hobby. After all, it just wouldn't do to show up and be in the position to take a great photo, and discover that your camera's broken.

The delicate nature of cameras is something that has only been magnified in the move to digital. Where earlier light-proofing the film chamber was the biggest deal, now it's keeping all the little electronics and tiny moving parts dust free and safe. Even the most rugged of SLRs is not something you want to toss around like a stuffed toy.

My Awesome New Raygun Toy

I don't mean for this journal to turn into just a documentation of whatever new toys I buy, but in this case I couldn't resist putting up a video.

Like Fish for Parking Spaces

My mobile phone is a gadget that has many of its cool-circa-2005 features going unused in my hands. Hindsight tells me I shouldn't have spent a small fortune on it -- money that I could now be putting to better use (camera lenses and beer) -- and that whenever I next buy a phone (i.e. whenever this current one conks off) it'll be cheap, tough, and filled with features that were cool circa 1995. For I never use it for anything beyond the basics of mobile phone communication; voice calls and SMS text messages. I can't update my facebook status, or twitter a tweet, make a scandalous desi MMS video that spreads like wildfire, or tell you how to get from one end of the mall to the other using GPS, and god knows when the massive tsunami that is the Google Wave eventually crashes into our always-on internet lives, it won't be doing any waving whatsoever.

And I like this about it.

Vishal Remembers a Lot of Cable TV


Nearly two years ago now we let the subscription on our cable TV lapse, and haven’t bothered to renew it since. In this age of DVD season sets, 24-hour streaming internet news and just plain frustration with the rubbish value for money that local cable bouquets offer, it made no sense to continue. Nowadays when I go to a friend’s place and see the TV on -- inevitably tuned to some flavour of news -- it feels like some kind of alien world. The last time I was on vacation in India I tried to spend some time flipping channels, seeing if I could recapture those feelings of discovery and entertainment that TV provided for a long time in my life, but it ended with me bored and angry, two hours later having not stayed on a channel for more than five seconds.

Strange things have happened since then. I find that the large chunk of space in my brain that used to be reserved for TV is shrinking. I remember TV, but not as well as I used to, and in a few years time I may not remember much of it at all. Hence this post, which is an infodump; a big steaming brick about TV and the way it was when I used to watch it. Because, though I loathe the way it is now, a lot of me has been shaped by TV, by that first viewing of Star Trek when was an infant, by entertainments factual and imaginary, by the rush of information and colour and sound.

TV was the internet of its time. And this is how I saw it.

Electrical Shenanigans

Right, so usually I'd just link to this in my Google Reader Shared Items blog, but one particular picture in this set was too good not to highlight. Just look at it. I want it blown up and put on my wall.

Prince of Persia Revisited

At the cusp of the 1990s, every home PC had to have one killer app installed. When you’d go round to a friend’s place and they’d show off their new Amstrad or IBM beige behemoth, the first question out of your mouth would be, “How did you convince your parents?” The second would be, “Do you have Prince of Persia?”

Jordan Mechner’s seminal 1989 game (published by Brøderbund) was the high watermark for computer games at the time, a title that combined fluid graphics, exquisite music and challenging gameplay into an astonishing final product. I remember the first time I saw it in 1990, on the PC of one of my parents’ friends. He fired it up for us, to keep us kids busy, I suppose, but I don’t think even he would understand quite the impact the next hour or so of play had on me.

Google Chrome & the Power of Comics


Over the next few days you will hear a lot about Google Chrome, the new web browser from the internet behemoth. I've tested it out and am happy to report that it's quite nice. Of course, I'm a long-time Mozilla Firefox user, so the transition has not been very stark. But if you're one of the poor people who still use Microsoft Internet Explorer (or worse, if until now you didn't even know what a web browser is and that there are mutliple available ones), then Chrome will be a revelation.

Even for me, the new browser is an intriguing new beast. It's very quick, intuitive to use and so far does things well. I can see myself using it for most tasks, at least those that don't require certain firefox plug-ins that I'm used to (but there will no doubt be equivalents for them in Google Chrome eventually), and I'm very happy that there is now a new robust, polished open-source browser. Competition and choice can only lead to better products in this regard.

But as impressive as the browser is, it is not the thing that I really wanted to blog about here. For you see, the most impressive thing about Google Chrome for me today is the fantastic comic that serves as an introduction to it.

The name Scott McCloud should be familiar to most comic book geeks such as myself. The author of seminal works like Understanding Comics has carved a name for himself as true master and expert of the comics medium. Who better to explain a new web browser; an application that's so simple to use it's invisible, but is so complex underneath that entire careers can be dedicated to it? Scott McCloud, of course.

I love how he manages to represent even the most arcane programming concepts in a fun and exciting way (helped, of course, by the words from Google Chrome's programming staff), how there's a single narrative thread but multiple voices from members of the team -- this is a feat you can't really achieve as well in video, for instance, but as a comic it works great. Alan Moore has always maintained that comics as a medium are rich beyond measure, that there are things you can do in it that you can't do in a movie or a book. I can think of several examples of Moore's own work to support this, but Scott McCloud's introduction to Google Chrome is a shining example too.

So even if you don't give Google Chrome a spin (I highly recommend you do), please do check out the comic that goes with it. It's simply superb.

Earth Vs The Legion of Lightbulbs

Yesterday was Earth Hour in several places around the world, including here in Dubai. Not much happened, though a few buildings did turn their external lights off. One lovely radio jockey suggested that the best way to spend the hour was to turn off all the lights, fire up some candles, snuggle up with your significant other on the sofa... and watch a romantic movie on DVD (preferably on your big screen HDTV).

Take that, energy conservation!
