Interesting macro lens
07:38 AM on Monday 30 September 2013
Stumbled upon this interesting macro lens with a 5X magnification. http://www.yasuhara.co.jp/nanoha/index-e.html That is some extreme magnification and it comes with its own lighting. The DOF is not too bad but stacking might be needed.
The art room at Pauline's school
08:37 AM on Sunday 29 September 2013
Was at Pauline's school to help her out with her art project. And I took the opportunity to take some photos of the interesting things there using the macro len. First up is a series of shots on plaster of paris. The air bubbles that form during the pouring of the plaster created some very interesti ...

HDR of the view from the house
06:55 PM on Friday 27 September 2013
Did a HDR using Nik HDR Efex Pro 2 which I recently brought as part of the Nik collection for HDR work. With Photoshop on the cloud and on a subscription basis, I wanted to move away from expensive Photoshop and Google was having a special for the entire Nik collection. So I brought that and the HDr ...

Parallelization in R
08:16 PM on Tuesday 17 September 2013
I have been having pretty large data set for statistical testing recently. Large as in millions of comparisons which is really taking a lot of time. In the past, I have used plyr and the doMC parallelization backend. That took a lot of time. The tests themselves seem to finish fast enough, but the a ...
Loop
08:07 PM on Monday 16 September 2013
Loop is a iPad app that allows one to create simple animated GIFs like the ones we used to do on our textbook pages. Esther created the one below of a bouncing ball. I created the one below of a badminton match. Isn't it cool. The best part is that it is really simple. Kids should have no problems ...
Evil bird
12:38 PM on Sunday 15 September 2013
I was hopping to catch this bird in flight so I waited with the camera aiming at him. But it seems to know and refuses to take off for the longest time. And when it did, I missed the shot :-( So what I had was couple of test shots of the bird and I thought that I might as well make the best of it.
