Exercise 2 : Exposure

Lecture 
In this exercise, Mr Vinod showed us how to use the Aperture settings. In definition, Aperture means to control the amount of light entering the lens and to also control the depth of field (clarity). Lens have a set of marked "f-stops". For example : f2, f2.8, f4....f32. The bigger the number of the Aperture, the smaller the whole in the lens and vice versa. If the Aperture hole is big, the depth of field will be blurry. 

Instruction

1.  Use a subject that is repetitive in nature.
2.  If you are using a zoom lens keep it fixed at 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 from the first image right till the last. DO NOT ADJUST IT!.
5.  Keep a record of the settings for each image shot 
6. Once exercise is concluded, download all images of this exercise into a folder and call it "Exercise 2a : Aperture"

Instruction - Exercise 2a

• Student must capture any image that is repetitive in nature starting with the lowest Aperture, right exposure and maintain the ISO at 200. 

• Start taking the photo with the lowest Aperture and gradually increase it but care to not change the shutter speed.

f/2                       1/1600                   ISO 200

 f/2.8                  1/1600                    ISO 200

f/4                      1/1600                     ISO 200

 f/5.6                 1/1600                       ISO 200

 f/8                        1/1600                     ISO 200

f/11                       1/1600                          ISO 200

f/16                            1/1600                  ISO 200

f/22                         1/1600                 ISO 200

Instruction -Exercise 2b

• Take picture using the right exposure, different Aperture and adjust the shutter speed.

f/2                   1/1600               ISO 200

f/2.8                      1/800                    ISO 200

f/4                           1/400                   ISO 200

f/5.6                        1/200               ISO 200

f/8                         1/100                         ISO 200

f/11                           1/50                      ISO 200

f/16                               1/25                    ISO 200

f/22                            1/13                         ISO 200

* Sorry for the 1st photo, I noticed that I didn't focus on the object right after I got home.

Reflection

For this exercise, I've learnt how to control the Aperture, Shutter Speed, Exposure and the ISO. I know understand that by choosing certain aperture, it will give out different type of clarity. While I was conducting this exercise, I was using a tripod stand. This is because the combination of the ISO, Shutter Speed and the Aperture that I used might make my image looks a lil bit shaky. I didn't know that by putting a little weight on the tripod stand can destroy my picture. So, I was told by Mr. Vinod to not lean, press or even move the tripod stand for it will make my image look blurry. 

So, basically. That's what I've learnt for this Exercise. Below is the screenshot of my folio.
