Brian's 21st and Healthy's 22nd!

Finally, the second last 21st birthday we'll have in our group, next is Rea. So this time, comparably it was a simple gathering. Just movie and dinner.

One thing that happened without us happening was Katy Perry was at Event Cinemas at Town Hall George Street Cinemas making an appearance on her new movie: 3D Katy Perry: Part of Me.

We watched "Brave" and we thought it might be a childish cartoon, but surprisingly it wasn't. To me it was a very emotional movie where a girl dislikes her mother deciding her every step. But until her mum turned into a bear, they both learnt much more about each other, and understanding each other's weaknesses and strengths. Their relationship with each other was strengthened through pressured and stressful times. 

We had  a simple dinner at Campbells Restaurant at Chinatown, and for the first time, we actually went to a Chinese restaurant, but ate steak... not bad of a place. The service was good and the food was good. Well worth the price.

I only took photos when we got out of the restaurant, and we got to this kind of stuff....

I'm kinda crazy about all this magical levitation right now, because I reckon it makes the photo look so much more interesting. I'm sure by now, most of my friends know me as the "friend who always try to get everyone jumping in a shot." Until now, it still hasn't happened, so I might as well do it on myself and to people who actually want to do it.

Then at Cockle Bay Wharf, there weren't any fireworks, but there was a permanent light display on the two new buildings across from the park.

But since my photos were blurry, I might as well make it apparent.

Tutorial: Overexposed VS Underexposed

So what's the difference between an overexposed and underexposed photo? The difference is that one is too dark, and one is too bright. Being that in the photo, some details are lost because of the dark or light pixels, which beams out, destroying all that detail.
A lot of people always ask me why I always use flash in my photography. Many people nowadays doesn't need to do this, but I do, because my camera isn't very good at handling high ISO levels, so about 400ISO, it starts being very noisy. If you don't know what I mean by noise, see here. So I tend to use my flash to at least expose it properly, otherwise, I've just a whole bunch of noisy photos to deal with at post processing time.
So lets see what's the difference between the two and how to tell:
This is an underexposed photo. It loses all the details in the dark parts like the shadows. And even to the eye, it's too dark. This is caused by a fast shutter speed, or a small aperture, or a low ISO.

So let's relate that to each one to this photo.
With shutter speed: it's too fast, and didn't get enough time to expose the sensor to the light.
With aperture: it is too small. The opening of the lens is not wide enough to let enough light in.
With ISO: it was too low, and it didn't have enough of them going out to bring the light in.


This is an overexposed photo. It has lost all the details in the bright bits, and basically it's TOO BRIGHT! This will kill your eyes, if it's in the full size.

Shutter speed: It's too slow. It took too much light in, and the shutter speed could be adjusted to be quicker.

Aperture: It's too big, the opening of the lens too every speck of the light and threw it into the sensor. 

ISO: It's too high, it put too much out collecting too much light.

So here's a photo that is nicely exposed. The blacks are not too black, and the whites aren't too white. It's good.

But having said that overexposing and underexposing is bad, there is ways to edit it, and which one is easier to edit? Keep an eye out for the next coming post! 

Last of College celebration @ Max Brenners

What do you feel like when you have accomplished something major in your lives? Cry? Laugh? Or Run away, not knowing what to do next? I typically would jump up and down like a maniac, shouting yeah yeah yeah until I lose my breath. That's what I am feeling right now.

It's been a year since I've started st Bedford College, and now it's the end. It's too fast. The time has gone too fast. And I still complain why some days hasn't been going faster? A year is like a lightning bolt! Before you know it, it's Christmas 2012, then New Years, and so on. Why complain that time is slow? That's just an illusion of not using time efficiently enough, and just doing things that isn't productive enough.

So since it was my (and other friends) last day at the college, instead of just jumping like maniacs, we opt for a afternoon tea at Max Brenners. Yep. Max Brenners, the bald guy, with lots of chocolate. I've been longing to go for so long, but hasn't been there due to either being too full after a gathering dinner or not having enough money. So this was my chance to have this famous chocolate place, and see how is it good, and why does so many people know the place.

I took a few shots with my friends, and yea, such yum waffles and icecream, icecream which I dearly miss...

This was the Tutti Fruitti Waffle.. It had a waffle, bananas, strawberries and ICECREAM!!

Another year, Another theme, Another exciting moment, At Vivid Sydney! (Part 1)

Once again, Vivid Sydney has come to Sydney again, showcasing the marvelous arts and creativeness the world has brought us into. This year, it has brought me into surprise that... The Opera House was so devastating! But other than that, everything else was pretty good, some were very abstract, and some was very nice to see.

The Opera House. In total they had about 5 designs, which most consisted of a female and male rolling around the Opera House. Pretty white I'd say. More colours would've been nice.

Among many sculptures by the sea, there were a few of them that were very distinct and special...

Then there was the Custom House, which made me so happy to be able to see it. It had a story to it this year!

After about 3 and a half hours, we only managed to finish half of the exhibit. I will go there again, and finish the next half again. Keep an eye out right here!

Tutorial: ISO

What is ISO?
ISO is the abbreviation of International Organisation of Standardisation.What does this have to do with taking photos? I have absolutely no idea. I'm just going to tell you how it affects your photos.

How does it work?
During the day, there are different types of brightness. This affects the sensitivity of the image sensor.

How is it measured?
It's measured in numbers and they normally double up from the previous number, so it starts of at 100, then 200, 400, 800 etc. Some cameras have different maximum ISO's and my camera only goes up to 3200, so all the example will be based on my camera, but the concept will be the same with yours definitely.
By increasing the number, the camera will be able to receive more light in less time. The way I perceive is like this: In 1 minute, I want to get 5 litres of honey. I first start with 100 bees, and that is not enough. I try with 200 bees, and that is enough to get me 5 litres of honey.
Does that make sense? Let's put it back into the camera concept. If I wanted to take a shot with dim lighting, and I wanted to keep the shutter speed at 1/50, I would need to put the ISO at 400. I hope that makes sense now.

PROs and CONs
Pros: Able to choose a fast shutter speed to freeze movement.
Cons: Noisier shots.

What do you mean... Noisier shots?! Are you saying my photos are going to make sound?!
Ummm... No. No matter what you do to your photos, they will not make sound by themselves. Noise is what is classified as grains or colour distortion. The higher your ISO is, the grainier it gets and it will affect the quality of the photo.

Tutorial: Aperture

What is Aperture? Aperture refers to the size of the diameter inside the lens.

So how does it work? Every time you take a shot, there is an opening at the lens, which opens up to allow light to enter the sensor. For each shot you take, the opening closes for the photo.

How is it measured?
It's measured in f-stops, and it is shown like this: f/number, e.g. f/1.4. The smaller the number the bigger the lens are open. Moving from one f-stop to the above or below, is halving or doubling in number and size, which means it's letting in either more or less light into the sensor.

How does this element affect photos?
By letting in less light (small f-stop, e.g. f/16), it will show more of the shot in focus. By letting in more light (large f-stop, e.g. f/3.5), it will put most of the shot in blur, keeping the selected part (chosen by you) in focus.

At f/3.5, only the first row is in focus

At f/5.6, the first row is in focus, and the second row is starting to become sharp

At f/8.0, the second row is in focus, and the third row are beginning to become sharp, figures are recognisable

At f/16, third row is in focus, and the fourth row is starting to come sharp

At f/22, everything on the shot is in focus. All detail is on each figure.

Tutorial: Exposure

After photographing for about 4 years, I have learnt many, many things. From the time I was using Auto Mode, switching into different modes (portrait, night, etc), then gradually changing to the semi-manual then the fully manual modes. So because I'm such a "nice person", I decided to share my knowledge for newbies or people who just need to remind themselves about their basics.

So let's just start with the easiest of all, exposure or shutter speed.
What is exposure?
Exposure is basically the term used for the amount of time the shutter is open for the light to hit the sensor. So the longer you leave it open for, the more light it receives.

How is it measured?
It is measured in seconds or fractions of seconds. The bigger the number, the longer it is open. So logically speaking 1sec is longer than 1/50sec.
Every shutter speed has their purpose to it. There is no right or wrong in choosing it, as it just depends on what shot you plan to make.
Even though there is not much rules to this key aspect, there are a few rules that you should keep in mind.
For any shutter speed lower than 1/50sec (e.g. 1/6, 1/3 etc...) you should use a tripod or some kind of support to avoid camera shake. Even if you don't have a tripod or anything cameras are coming out with built-in image stabilisation which helps stop camera shake up to a few stops down.

How can I effectively use it?
Well, here's a question you should ask yourself. Do you want to freeze movement? Do you want to show motion?
Freeze movement: For this option, you will want to use anything faster than 1/750sec. This also depends on how fast the subject is moving. So have a judge before you do anything.
Show motion: Anything under 1/200. Even though 1/200 is quite quick of a shutter speed, the subject can be blurred depending on how fast it is travelling. So again, judge on what your subject is, and how fast it is travelling.

At the speed of 1/250 of a second, you could see some blur, but you can still see the shape of the cylinder. But at the speed pf 1/6 of a second, all you can see is blur, and obviously after that, it just get's blurrier.
