Introduction to Photography
Exercise 2 (Shutter Speed & ISO)
Lecture: Shutter Speed
And yet, for the forth week or our lecture have been re-explained again by Mr. Vinod about our ePortfolio of the reflection. We have to be much more in detail with " What is our experience? " , " What we have understood? " , " What do we realized? " , " What we have taught? " So, he expect to see it in our next slide of our ePortfolio. And also, he wish every single of us to have trial information/knowledge so that all of us can catuh up easier.
So after that, lecture started. Still, I would like to share the knowledge of what I have gained from today lecture.
Shutter Speed: is the duration of time the shutter remains open to allow light to reach a digital camera sensor(CCD).
: is measured in seconds, or fractions of seconds.
Photographer often use a very fast shutter speeds “freeze” on fast-moving subjects.
Let's explain this way:
 |
| Fast Shutter Speed |
If fast shutter speeds are able to freeze the image, slow
shutter speeds have the opposite effect--slow shutter speeds allow you to get creative with blur/used to intentionally capture the movement of a subject.
For example:
 |
| Slow Shutter Speed (The result demonstrates the principle that, with slow shutter speeds, anything that moves will blur (in this case, the lights of moving cars), but anything stationary in the photo will stay in focus.) |
 |
| Motion blur due to slow shutter speed |
 |
| Long shutter speeds can create astonishing effects |
 |
| Camera shake due to slow shutter speed |
**For
most, hand holding a digital camera at shutter speeds below 1/30th of a second
often require use of a camera support to prevent camera shake.
This video was taken by me during the lecture. It's all about the last instruction of our exercise(shutter speed) :*Sorry for the keep blurring because this is the first time I am actually taking a video by using DSLR. (=/)
1. Set an object.
2. If you are using a zoom lens keep it fixed at 35mm (50mm)
3. When you mount the camera on the tripod don’t move the framing till the exercise is concluded
4. The focus must be at the same point (centre of the frame) from the first image right till the last. DO NOT ADJUST IT! J Keep a record of the settings for each image shot.
2. If you are using a zoom lens keep it fixed at 35mm (50mm)
3. When you mount the camera on the tripod don’t move the framing till the exercise is concluded
4. The focus must be at the same point (centre of the frame) from the first image right till the last. DO NOT ADJUST IT! J Keep a record of the settings for each image shot.
**Once the exercises are concluded, download all images of this exercise into a folder and call it “Exercise ( 2b - Shutter Speed) , ( 2c.i & 2c.ii - ISO )”
Instructions: (Exercise 2b - Shutter Speed)
1. Use a fan and keep the fan speed at 1 and capture images using shutter settings from 1/4th of a second till 1/1000th of a second.
2.Repeat this exercise after changing the fan speed from 1 to 2 and the from 2 to 3 and so on.
3. If you are using a zoom lens keep it fixed at 35mm (50mm) yet it is depends on the high of your fan.
4. If the environment is slightly darker, try to open up all the light and windows to get a better result.
5. When you mount the camera on the tripod don’t move the framing till the exercise is concluded
6. The focus must be at the same point (center of the frame) from the first image right till the last. DO NOT ADJUST IT! J Keep a record of the settings for each image shot.
**Once the exercises are concluded, download all images of this exercise into a folder and call it “Exercise 2b - Shutter Speed”

Exercise 2b - Shutter Speed
----------------------------------------------------------------------------------------
Instructions: (Exercise 2c.i & 2c.ii - ISO)
1. ISO
exercise 1: you
will be required to shoot a subject using the lowest ISO setting to the
highest. Determine the right exposure (shutter speed & aperture @ ISO 100)
and then increase the ISO setting to 200, 400, and so on.
2.ISO exercise 2: Determine your exposure (shutter speed & aperture @ ISO 100) but this time adjust the Shutter & Aperture to maintain the correct exposure as you increase the speed of the ISO.
3. When you mount the camera on the tripod don’t move the framing till the exercise is concluded.
4. The focus must be at the same point (center of the frame) from the first image right till the last. DO NOT ADJUST IT! J Keep a record of the settings for each image shot.
**Once the exercises are concluded, download all images of this exercise into a folder and call it “Exercise 2c.i & 2c.ii - ISO”
2.ISO exercise 2: Determine your exposure (shutter speed & aperture @ ISO 100) but this time adjust the Shutter & Aperture to maintain the correct exposure as you increase the speed of the ISO.

Reflection: (Exercise 2c.i)
For the Exercise 2c.i I could noticed that my light exposure keep on boosting from 100 to 200; 200 to 400 and so on. I can see much more clear different between the first photo and the last photo. At the first photo. I can still see the transparent bottle (which is the white glass bottle) clearly. Yet, when I increased my ISO to 3200, I can not even see there is actually a transparent bottle (which is the white glass bottle) there if i did not go in detail. When I enlarge the last photo, I could have seen a little bit of out line of the bottle. And so, I can even noticed that the second bottle (which is the dark green bottle ) the colour has totally different compare the first photo and the last. This may due to the light exposure since I just increased the ISO setting. The higher the ISO rating (more sensitive) the stronger the image sensor has to work to establish an effective image, which thereby produces more digital noise (those multi-colored speckles in the shadows and in the midtones).
Reflection: (Exercise 2c.ii)
For the Exercise 2c.ii can I just say that I see no change in the two photo, yet it is actually a slightly different between them. At the second photo, the photo seem a little bit darker. This may due to when the ISO keep on increasing, I have actually also reduced my shutter speed. Therefore, my camera gets to balance my exposure.
General Reflection:
Generally, throughout this lesson, I could have clearly understood the ISO and the Shutter speed that I was confused for a long time. It doesn't goes smooth at first because I was still blur with it. Yet, when comes to activity, my problems were solved in a shoot. During this session, I can understood much more on Introduction of Photography yet to find the easiest and the fastest way for me to understand everything. What I trying to mean here was; by running the activity, it is the most easiest and effective way for myself.

Feedback:
Wohoo! For my reflection, by Mr. Vinod, I have did really well in it. Nothing much to comment on. He likes the way I explain and the way how I could understand a new topic. He wish I could keep on this way and be much better.
Yet, the second was, in my reflection 2c.ii, it is much better that I could mention the ISO for the both pictures at the bottom. He advised me to crop a small part of my exercise 2c.ii, the first picture and the last picture for compare so that others may be more understand. For example:
This is all the feedback gave by Mr. Vinod about me. I will keep this up and produce a much better result next!

As I can noticed from above was, at the second picture which carry the ISO 3200 have a lot of small green grain around (noise) compare to the ISO 100.
This is all the feedback gave by Mr. Vinod about me. I will keep this up and produce a much better result next!
