Prime Lens - Back to Basics




A kit lens makes you lazy. This is the first thing you learn when you step out of your comfort zone in photography.

I have been photographing with an 18-105mm lens for more than 10 years now and thanks to the convenience of zooming in and out, I had all but forgotten the basics of photography. I knew I needed to get back to the basics, to detox, to relearn, and a fixed-focus 'prime lens' seemed the best way forward.

The ones I could afford were shortlisted to the Nikkor 50mm 1.8 lenses which came in two types 'D' and 'G'.  The 'D' was a older version without an inbuilt focusing motor, and it came for less than half the price of the 'G'. Since I was using a camera body that already had a motor the former seemed better value for money - especially when it came at an an extra discount during the recent Amazon Sale.

So last month, I set aside my kit lens for the first time, and twisted into its place a brand new 50mm 1.8D. The Nikon D90 now felt like a strange new animal - lighter, faster and sharper than ever before, and yet completely unfamiliar. Despite clocking nearly 50,000 'shutter actuations' on the D90, I realised that  knew very little about the nuts and bolts, the basics of photography: focal lengths, F-stops and apertures.

They say the 50mm lens shows you the world the way your eyes see it, by "rendering images that closely match the true perspective of the human eye". Sounds nice... but when you look through the 50mm lens for the first time you feel like a horse with blinkers plodding through a tunnel. The world shrinks. Instead of just zooming you now need to use your feet and composition becomes a bit of a struggle.

The 50mm lens is also a bit puzzling with all its numbers and dials packed into a tiny ring. So here is a collection of links that has helped me re-learn photography -

In Praise of Bootstrap3


In the world of web-design I am a bit like Rip van Winkle - a solitary rustic who once dabbled in ancient HTML; the oldie who goes off to sleep for 15 years and then wakes up to discover a digital world that has been completely transformed.

Nothing remained of the familiar landscape. Old HTML had become too primitive, too cumbersome and simply incapable of showing up on anything other than a clunky old PC. As webpage designing had moved from one version of HTML to another, the newer versions had teamed up with CSS and outsourced all the layout grunt work, Java and JScript had come in to add heft and magic to the amazing things that could be accomplished using smartphones, tablets, and laptops. A bewildering new world that would not reveal itself in "view page source".

It is while wandering through this maze that I stumbled upon the answer to all my problems - Bootstrap3. It was built on whatever little I knew of HTML and CSS, and then, with a few online stylesheets helped me create websites that worked beautifully across platforms and devices. Magic!

Here are links to the sites that were a big help:

* GetBootstrap (Currently at v.3.3.7) - Home - http://getbootstrap.com/
Repository of all the latest download files, Content Delivery Networks (CDNs) and sample pages

* YouTube - Lalit Bassi's Bootstrap3 Tutorial (1:40 hrs) - https://www.youtube.com/watch?v=gqOEoUR5RHg
Even after downloading Bootstrap, I was quite lost until I stumbled upon this much-viewed tutorial. Starting with a simple HTML layout, this video takes you through a wide range of functionalities that can help you launch a fully functional website is a few hours. It also introduced me to the joys of using SublimeText - an editor infinitely better than MS-Text!
Caveat: The Dilliwala Yankee accent can be tough...but remember: no pain, no gain! ;)

* YouTube - Bucky Robert's TheNewsBoston (14 short clips)- https://www.youtube.com/watch?v=qIULMnbH2-o
Unlike Bassi's package this one tells you about various different tools in short, easy-to-understand videos.

* YouTube - Bootstrap tutorial by Derek Banas (1:04 hrs) - https://www.youtube.com/watch?v=gqOEoUR5RHg
More like a catalogue presentation of the various things you can do with Bootstrap3. Derek keeps adding and deleting code so you might be disappointed to find many components missing in his final "cheat-sheet".
