An interesting week

The temperatures dropped this week significantly. The hand which is still trying to close the gap in the bone, is feeling a lot of pain because somehow the metal pieces inside are stressing out the bone.

That has meant no sleep from 4AM to 6AM the first few days this week. Wrapping the entire arm in warm fleece blankets helped a lot.

Then the wife fell ill and between work, the kids calling me a "bad parent" and more pain in the wrist trying to exert myself, it has been a challenging week to say the least..

Going to do some camera accessory shopping tomorrow to cheer myself up.

This weeks photo homework assignment is "Bokeh" and it appears that I am way out of my league here.. Spent two hours to understand the concept (which is to highlight out of focus objects to create light patterns in the background)..

But here are some interesting results (going to work on this some more.. how they manage to get the object in the foreground in focus while still creating the shaped Bokeh is beyond me.. at least for now)

Cut out a star shaped hole on a cardboard and taped it to the focus ring..

Every point of light takes the star shape..

Notice Jr.'s eyes.. even her eyes show the star pattern (reflected from the flash).
Every light point on her necklace takes the shape of the star..

Cannot understand the physics behind it either. A flashback...

When we were going to IIT Physics coaching class, Balu Sir (god rest his soul) told us to go practice with MIR publishers book by Russian Authors "Tarasov and Tarasova" to master Geometrical Optics. There were no copies that we could get our hands on, but the platform book seller who used to have a shop at the bend near Nalli in Pondy Bazaar told me "Tarasov-aa thambi. Oru copy irukku pa.. aana Tamil copy, paravaa illiyaa?" (I have a copy kid, but it is in Tamil, you still want it?)

Two of my friends who saw me buy that book thought I was nuts. Understanding geometrical optics by reading a Russian book translated in Tamil?

Spent the next week understanding the terms for convex, concave, focus, object, image, radius of curvature etc. etc. in Tamil and figured it all out. It was actually very entertaining and rewarding.

But this Bokeh thing, beats Tarasov and Tarasova..

I hope your arm is better now, Sundar.
Are you having physiotherapy?
I hope San is better too, and you are no longer considered a bad parent!
