Photography 101: Long shutter exposure.

The picture above is a sample of a long shutter exposure. It was taken with 1/8^th of a second with F7.1. Super Steady Shot ON, handheld. A man with his satay. A long exposure picture is a good example on to show the pathway of the fire, and also the movement of the man.

 

What is a long shutter exposure? Well, what is shutter anyway? ;-)

A shutter is just like a window blinds. If it is open, it’ll let the lights come in. If it is closed, it won’t let any light go through. The window glass is your lens. Behind the shutter is the sensor (this is only applicable for digital cameras). The sensor is very sensitive to light. When the sensor is exposed to light, it’ll draw pictures. Basically, that is how a digital camera works.

 

Light go through lens, through an opened shutter, exposed the sensor and produced pictures.

 

If your shutter opens too long, you’ll risk an over exposed picture. What is an over exposed picture? A picture which looks too bright, lost details on most of the subject, and worst case, it went white. If your shutter opens too short, you’ll risk under exposed picture. A totally opposite of the overexposed, still not that much details captured, and worst case, it went black.

 

But, how can I create a nice long shutter exposure by not risking my picture to get overexposed?

 

Not that hard. Remember the basic principal of window & blinds? Yes? Good. Actually there are one more thing to that basic. It is the aperture. It is basically the opening diameter of the lens blades. Means, in other words, between your blinds and your window glass, there are another blinds that are adjustable on the amount of light allowed to come in.

 

In simpler noob calculation, if a perfect picture (P) is 100% consist of 50% (S) shutter opening and 50% (F) diameter of aperture

 

100% P = 50% S + 50% F

 

If you still want a perfect P but with higher (& longer) S, you’ll have to minus the F:

 

100%  P = 70% S + 30% F

 

And vice versa.

 

BUT in photography, a smaller F means that a bigger in F numbering format. For example, F2.8 aperture is bigger than F16 aperture. I think you’ll get confused with it. Ok, example below:

 

100% P = 1/125 S + F2.8

OR

100% P = 1/4 S + F16

 

In example 1, a higher S is needed to get a perfect picture, but your Aperture has to opened big enough to let the light come in through. In example 2, a slower S is needed to let more lights come in because the Aperture is small (not that many lights allowed to go through the lens as the aperture opening is small).

 

Slower S means that your camera has to be that steady and should not move at all to let the picture evenly formed. If else, you’ll result in ‘shaking’ picture. And if you purposely want a shaking picture, just don’t put your camera on tripod~ ;-) Take long shutter picture while jumping, then you’ll get it. Happy shooting Long Shutter Exposure pics!

Options

In life we have options. Is there anything such as 'no options?' I don't exactly tell. Complicated circumstances, yes. But anyhow, options will result in decisions. Either it is a right decision or a wrong decision, they are your decisions..

I am a computer programmer. While I may not extensively writing programs anymore, but I like to write programs. There are many languages, C, C++, VB, UniVerse, jBase, or even SQL, the main ingredients are just equally the same (for some sort). They contains: IF, ELSE, THEN, FOR, CASE, DO, WHILE and the most important thing is END. I can relate this to our life, and yes, they 'are just equally the same (for some sort)'.

No matter what you do in life, no matter what language are you verse with, the things are just the same. The only difference is the way. Whatever you do (or decide), there are always in 'cause and effect' clause. IF you do this, THEN this will happen. WHILE you do this, IF you come across this, DO this. ELSE, do that. In CASE the thing is this, you DO that. IF the CASE is this, you DO that. Our brain is so that powerful that they can 'write' their own programs, without you realizing..

Your brain store A LOT OF PROGRAMS.. You, yes you, helped in the creation of the programs.. Any program will have options. Most of my 'writable' programs will have IF THEN ELSE in it, some of it contains just too many that me myself would have difficulties on 'reading' it all again after leaving the program for some time. But worry not, your brains will not have any problem on reading it all again, rewrite the programs, edit, or even delete them. It is an unfortunate if somehow our brain is damaged and failing to read and write those programs anymore.

We have options, and we always think of options.

Options. Think of options. Don't blame others or blame اَللّهِ for not giving you options.

Since we have so many options, its up to you to choose one that best suits you, or option that is better for others but not you. In Malay traditions, we are being thought to always have courtesy. It is a very good thing to have, but as always, you are the one who possess the key to choose. You decide you own self (and the one that relies on your decisions)

Most people will not liking 'programming language class' (furthermore if you're required to take it for exams), but I don't know why, I like it from the very first minute up till the time of writings. I would say for the rest of my life? But that would be over exaggerating.

Did I mentioned about the most important thing is the END? Your program is not a program, not until it had the END. You do the thinking.

END.

Missed

Missed could have meant many things. I missed the train. I missed her. I missed the spot for an inch. Completely missed the point of the conversation. Honey never missed to call her mom. Missed my blackberry while in the train. Missed Universe *joking*

 

But anyhow, I am missing them. My honey and Naima. This morning was the first time in my life, leaving home with Naima alone, while honey stayed at home. Feel abundantly  awkward. No joke. The moment I set her to the nursery, feels like crying, feels like I wanna take her along to the office. But that is not possible. As yet. Not until I owned my own office, not until then Naima..

 

Life’s like that. One have to change to change oneself. I thought I have heard that too many times. Yes, I did.

 

Missed. A lot of things.
