Ok.. first.. let's have some more fun with Adobe CS 3. Here's a low light shot with the A700 and CZ 16-80mm lens at 16mm wide open. It is purposely underexposed by 1 stop to capture the night atmosphere during the mid-autumn festival some time ago. This is an image take from my study room's window using version 4 firmware of A700

Top left - Adobe Camera Raw convert with focus on getting more details in this high contrast setting, colours a bit flatter but we get the most details from the dark shadows. Comes with NR.
Top right - Image Data Convertor with default settings, i.e. NR etc... most pleasing colours but the details suffer from poor NR and other limitations
Bottom left - Adobe Camera Raw convert with focus on getting the most pleasing image balance with details... No NR..
Bottom right - same as above but with noise reduction.

Crops below (not really 100% but close)

All the smoke from the sparklers causing a lot of problem for the NR algorithm for all 3 cases. Most pleasing will be the bottom left without NR. The smudge effect of NR is clear here.

Yeah.. this is fun...

S$97 for Adobe CS 3 (Web Premium), including a free upgrade to CS4 too... it's 'mai tu liao', time to grab two sets. Here's some tweaking with Adobe Camera Raw.. something I have been thinking of trying for a long time.

Default settings pulled a lot of details out from the shadow but the colours look flat
Auto settings pull even more details from the shadow leaving the colours even flatter...
After some tweaking.. this is the best results I can get for 1/2 day worth playing with ACR. Finally I get some control over noise, just nice now that A700 v4 firmware can turn off noise reduction, leaving a pleasing image in the raw files

Just for comparison, this is from IDC default camera settings. I like the default colours that come out though now I find the skin tones to be better with the ACR and it is much easier to tweak settings with ACR compared to IDC.

IDC gives good results straight from craw with no tweaking but it is hard to do anything more... I hope I can find the optimal settings for ACR to batch process images soon... whoohoo.. so exciting...

The Enquirer is an online publications by NTU students as a reaction to NTU pulling an article related to Dr Chee Soon Juan from being published in their own periodical. One of the recent article talks of Dr Vivian Balakrishnan's forum and this was one of the points raised in the article.

When Shan, a second year political science student, asked Dr Balakrishnan about Singaporeans who were affected by the mini-bond fiasco, the minister in turn asked her whether he should approach the problem as an economist or politician.

Her simple reply—to look at the issue from the eyes of an “ordinary Singaporean”—won the applause of the audience.

No doubt many, if not all, of the issues raised during the forum have some impact on the political governance of Singapore, but Shan pointed out the more direct and critical link: the ones affected are ordinary unpoliticised Singaporeans.

I'm keen to know what was his response to Shan's reply. How could we look at the mini-bond fiasco from the point of view of an ordinary Singaporean. Unfortunately, the writer for The Enquirer felt that this was not an important point to discuss and I will never know what Dr Balakrishan said.

Let me suggest how we can look at the mini-bonds issue from the eyes of an ordinary Singaporean.

As the ordinary Singaporean who sold the mini-bonds, especially those who continue to sell these mini-bonds when Lehman Brothers were already facing problems, do they know what they are selling? If they do not know what they are selling, are they irresponsible Singaporeans, if they knew what they were selling, are they immoral Singaporeans? Did they explain to their clients clearly what all those financial terms meant? Did they mis-sell the products as another fixed deposit plan? Is there something wrong with Singaporean values or morals? If they mis-sell the products, is there any reason why they did that?

As the ordinary Singaporean who bought the mini-bonds and lost their much of their savings, do they know what they are buying? Aunties will spend 5-10 minutes to choose the best oranges at 50 cents each in NTUC, why is it that they do not know what they are buying when they spend tens of thousands? Is it because of greed that affected their good judgement? If they do not understand what they are buying, why didn't they try to understand it better? If they do not understand English, why didn't they ask someone else they trust (like their child)? Is the ordinary Singaporean too trusting and naive? If they knew what they were investing in, why did they put all their eggs in one basket?

As an ordinary Singaporean, how should we invest based on our financial capabilities. What should we do to safe-guard ourselves? Rely on the government all the time? Promote dependance and a nanny state? Should we learn how to manage our own finances?

As an ordinary Singaporean, do you want the government to have many rules and regulations to govern how you do things? That you need to keep $20,000 in your bank account that cannot be invested like in CPF? Do you want to sign more forms? Pay more and engage the services of a third party to explain such complex products for you?

As an ordinary Singaporean who is not involved in the mini-bond fiasco, what is it that you can do for those involved? What can you do if you have people around you who sold these mini-bonds irresponsibly or immorally? What can you do if you have people around you who bought these mini-bonds without knowing what it is? Or simply made a really bad investment decision?

As an ordinary Singaporean indirectly involved in the mini-bond, for example as the manager of those who sold the products, did they check that they do so responsibly and morally? ... and the list goes on...


In the perfect world, this would not have happened. The responsible and moral ordinary Singaporean will not sell such products to ordinary Singaporeans. The diligent and well-informed ordinary Singaporean will not buy such risky products. If you approach the mini-bond fiasco as an ordinary Singaporean, you still have to start with yourself. But as a politician, it will be very insensitive to say that, because not many people are willing to point their fingers at themselves.

To those who mis-sold the products etc

Heroes are celebrated for their deeds and contributions to mankind, they are never remembered because of their wealth or intelligence.

There are many Science competitions in Singapore for students to take part in, and we can classify these competitions into some of the following categories.

Quiz type - The most common type of competition, and possibly the least scientific of them all. Quiz based competition is the easiest to organise, to judge (only right or wrong) and yet it can be the most entertaining of all types of competitions. We can do it in a Pyramid game style, Who wants to be a Millionaire style etc. The feedback is instant and the majority gets very impressed with the student who can spell "Geobacillus stearothermophilus" and identify that it is a cause for food to spoil. You don't need to know Science, you just need to memorise everything about Science. Like what Feynman said, what's the point of memorising Science when all you need is a few seconds to look up the answer? The winner will be the guy who is a walking wikipedia.

Short-term project type - Usually students will be tasked with a project and given a short time frame (hours, days or even weeks), they may be given materials or a seminar on the project and the students will come out with a product at the end of the project. On the competition day, students will have to present their product or take part in some form of race with their products. Some science may be involved in the design and making of the product but the level of science involved various from project to project. For instance, you do not need to know science to build a bridge, though some science background will help you in improving the design of the bridge. These type of competition can be very exciting and entertaining but the bulk of the competition is actually conducted behind the scenes when the students build their products.

Long-term project type - Maybe it is a new invention to improve life, maybe it is a research project that advances our human knowledge. Students usually take months and perhaps even years to make or study something that little or nobody have done before. This is Science (and perhaps Engineering for inventions) at its core. Unfortunately, these are the most boring type of competitions because it is not assessible to the general public and the winner is decided by a panel of expert judges. Much like the Nobel Prize, the excitment comes only when they announce the winners. Are you sure you want to watch 100 hopeful candidates present what they found out about Zebra fishes etc?

--------------------------
Hence the most entertaining form of competition, the type that you will get to see on television, is actually the least scientific of them all. How ironic! Do we want substance over form? Is it better to have students who can give us, word for word, the definition of Newton's 3rd Law in Latin or to groom students who win awards because they know what is Science?

In the ideal world, if we tackle the substance, the form should come.... But seriously, these are two opposite directions in the approach for preparing students. (I know because I organised competitions before and the winning team comes had students who mugged University level textbooks before the quiz) In the ideal world, the public, in particular parents, will place more emphasis on substance.

Attempt at a more artistic angle (a.k.a. the nosy neighbour angle or the kaypokia angle)
Doing his rolling job well
Tired from all the mopping...
But it was all worth it.

The Right Attitude

Cannot Attitude: After exams students won't bother to learn so I can't teach
Can Attitude: I don't have to worry about assessment after exams so we can have some fun teaching and learning.

Cannot Attitude: I have so many things to do and I can't finish it if I do it the same old way!
Can Attitude: I have so many things to do, perhaps I can try a new way to do it.

Cannot Attitude: I am limited by this and that hence I cannot do what's important
Can Attitude: I may be under constraints but I need to do what's important too, maybe I can try to fit it within constraints by making some adjustments here.

It's dangerous to get into one's comfort zone, develop this cannot attitude and build up an aura of negativity. The challenge is, how to develop this can do attitude in students and teachers alike and be creative in the way we work.

SURE CAN MAKE IT!

Farewell Photos



Farewell Ceremony 2008


Now get back to studies... You will get this if the school decides to burn another DVD for you, otherwise I will try to get one copy made for each class to re-distribute.

May you remember the lyrics of the song we presented to you yesterday

光辉岁月 - Beyond

一生要走多远的路程
经过多少年
才能走到终点

梦想需要多久的时间
多少血和泪
才能慢慢实现

天地间任我展翅高飞
谁说那是天真的预言

风中挥舞狂乱的双手
写下灿烂的诗篇
不管有多么疲倦
潮来潮往世界多变迁
迎接光辉岁月
为它一生奉献

一生要走多远的路程
经过多少年
才能走到终点

孤独的生活很需要时间
只要肯期待
希望不会幻灭

天地间任我展翅高飞
谁说那是天真的预言

风中挥舞狂乱的双手
写下灿烂的诗篇
不管有多么疲倦
潮来潮往世界多变迁
迎接光辉岁月
为它一生奉献

---------------------------------------------------------

I wanted very much to address you guys yesterday, but I did not, here's what I have to say.

I hope you will like the compilation of photos for the past 2 years in the DVD and the design of the cover. I hope you liked the video that the teachers and I put together for you. I wish you all the best in the 'A' levels. And for all my 40 Physics students, I hope you guys 'enjoyed' your very special Prelim paper. You will always have a very special place in my heart, remember, if you need help in Physics, it's only an email/phone call away. That's my 3 gifts for you before you go, DVD, video and my blessing

Good Luck everyone!
