Science of the Arts

This blog post is about how Science can improve my art in the festival of the Arts Kete.

Aim:
- I want to research the history of Obscura Camera
- How does pinhole camera or Obscura camera Work?
- I want to investigate how to make a Obscura Camera.
- I want to investigate how chemicals react with light to make a photograph.

Research:
History of Obscura Camera (Obscura Camera)
How does Obscura Camera Work (Obscura Camera)

Base on my research, Camera Obscura have taken place since very early times. The first recorded evidence of this effect was by Mo Tsu, he was a Chinese thinker in 500bc. Lenses has to have its focal length to be fixed. The brightness and clarity of image that the lens introduced made it a practical tool for artists like Vermeer and Canaletto and perhaps encouraged more experimentation. Camera is a Latin word for room or chamber and Obscura is a Latin word for dark. Camera Obscura means dark room. Putting out the camera obscura out in the landscape, rays of light reflect of objects in the landscapes and bounce of in all directions. Most of the light will be scattered, but some will make it through the opening in the camera obscura. The reflected light will be the same colour as the object in the landscape, light reflects off other objects as well. All of the spot of light combine to form an image on the back of the camera obscura. If the opening in the camera obscura is large, the rays of light are large. It makes a bright and clear projection because a lot of light is allowed in. But it can also make the picture blurry because the projections are large and overlap quite a lot. 

How Chemicals react with light to make a photograph. (Pinhole Camera) 

Light sensitivity, of the Silver Halides, is the key to the photographic process. When light is exposed, a chemical reaction darkens the film to produce an image. Silver Halides is one of the Halogens. Silver Halides are light-sensitive chemicals, and are commonly used in photographic film and paper.

Equipment: 
How to make an Obscura Camera (Obscura Camera)
- Magnifying Glass
- Baking or Tracing paper
- Cardboard or box
- Mirror
- Electric Tape
- Craft Knife
- Other design materials
- Glue gun
- Scissors
- Pencil
- Ruler
- Light bulb or lampshade



Method:
(Link to Instruction) (<----- in youtube)

1. First figure out the focal length of your magnifying glass. Using the light bulb or the lamp shade, test the focal length of a magnifying glass by testing it somewhere dark and using the light bulb. (Put the magnifying glass in front of the light bulb testing it in a wall that's dark. Test the the focal length by moving the magnifying glass forwards and backwards until you can get the right focal length. You will know the right focal length when the picture of the light bulb is clear and when its not blurry. Then using a ruler, measure starting to the wall and to the magnifying glass.)
2. Second make the side of the boxes, it includes; the top, bottom, left side, right side, front and the back side. (All sides should be cut separately).

3. Then using the glue gun, stick the bottom, the right side, the left side cardboard all together. 

4. Then make two small stands (looking like a rectangle) to put on both sides of the box, also make a piece of Cardboard to put in front of your stand.

5. Glue the two small stands in the side of your box and putting it on an angle of 45 degrees angle. Put the piece of cardboard in front of your sides and going in an angle as well. 

4. Glue the mirror in the piece of cardboard (The cardboard that is glued in the stands)
5. You can now stick the back side cardboard onto the back of your box.
6. In the front side cardboard, make a circle hole for the magnifying glass. After that, stick the magnifying glass to the hole.
7. Glue gun the front side in the front of your box (Make sure to put the front side on the measured focal length).
8. Using the top bit of your box, cut a square which you will put for the tracing paper. After cutting a square, tape or glue the tracing paper (But I recommend to tape it because if anything goes wrong with your tracing paper you can easily get it.)
(Making that top bit)
9. Now, we have to make a small Necker cube without a top and bottom. Make the sides of the Necker cube and glue them all together (no top, no bottom).
10. Glue the top cardboard into the top of your box (Make sure that the tracing paper is above the mirror).
11. Then glue the Necker cube cardboard in the top of your tracing paper (Make sure the Necker cube cardboard is in the exact place, in top of your tracing paper, this will be your viewing screen.)
12.  Then your Obscura Camera is all finish, all you need to do is to design.

Results: (Write down what I saw)
As a result, my obscura camera was successful. I was able to look at it with a clear and bright projection. Also I have learned a lot of things, I have learned how it works, its history, why is it able to reflect its light and other more things. This experiment has proven me that camera obscura actually works. Before I thought this experiment wouldn't work. Also I thought that the camera obscura has its images different to a real camera's images but after the experiment, I've proven that the camera obscura is actually like a real camera. Both obscura camera and a real camera has clear and nice quality projection.

Discussion: (Write down what happened or why/how it happened)
I have been observing and have been working hard to find out how the obscura camera works. I found out that the magnifying glass reflects the image and can make the image that is far to be larger. I have learnt that, to be able to make a clear picture using a magnifying glass, you have to discover the right focal length of the magnifying glass. 

Evaluation: How did your experiment go? What was a success?
I was so satisfied by experiment or project because I didn't expect it to work, since I don't know anything about obscura camera in the first lessons. I have learnt a lot of it and now it all makes sense to me. I have been able to do it successfully and I have manged the camera obscura to work.

Writing Term 4 Week 1 & 2

Writing Term 4 Week 1 & 2

9th of October, when it all happen. This is the day when I felt scared and unfamiliar. They say that having an appointment in that place would go fine, but for me it went unusual. Early in the overcast morning, in the second week of term 3, me and my family was having a superior holiday, just by spending time at home, especially my siblings. They probably won’t endure if there wasn’t any WIFI. Well I can live without WIFI. Anyway, it was all going well until the word “you’re having a check up with the doctor” came out in my mother’s mouth. How shocking it was for me and how could I not react to that. All I said was the word WHAT! to my mother and I think she was expecting me likely to be happy. Just because I had a lot of experiences with doctors doesn’t mean I’m used to it. I know for sure that I do not like seeing doctors. I thought it wouldn’t go any worse but it did. The worst thing is that I'm not just seeing my usual doctor but a different one. A specialist one. I never had any experience with specialists! But I’m pretty sure they’re more scarier and worse than my usual doctor. In my opinion, a specialist can be severe and scary. Scarier than the clown in the movie titled “IT”. I’m not trying to be mean or something, but I’m just telling the truth. Then a complain came out of my mouth “This can be a pain” I whispered to myself with a sight of miserable. I took a shower, I packed up and brushed my teeth, getting ready for the appointment. Taking a step outside and heading towards the car with my whole family in it. Are they coming to support me and to cheer me up, or are they coming just to tease and scare me? I just thought that this is too much thinking for today and I’m just scaring myself thinking negative thoughts. This is all because of fear and I blame it. A few minutes later, hearing and seeing raindrops in the window in the side of the car, makes me out of my stress, and seeing new buildings around the city makes me feel a bit better. A few minutes later, turning around in the street over there, observing the place called “Specialists at nine” makes me worry again. That word “Specialist” is really getting on my nerves, and having that “awhhh” moment, complaining and overthinking. Then the car stopped at that place called Specialists at nine in the parking lot. “Goodbye! And have a great time” Dad said. How am I gonna have a great time?, I asked myself. “Yeah” I responded. Then I took a step outside, appreciating the beauty of nature while raining and smelling the scent of the cold fresh air. It was all pleasant but will my appointment be? I was already over thinking, again! Then I looked around, while mum was outside with me having a conversation with dad through the opened window in the car. “Just call me when you guys are finish, and we will be around the city roaming around.” He said. “ Yeah, ok” mum replied. Me and my mum was walking in the pavement near the hospital. In my view,  the hospital looks like an apartment. We were going towards the entrance which has a glass door. When I arrive inside the hospital, I noticed some names. Names of the specialists. “Mum, what is the name of the specialists, that I’m having an appointment to?” I asked. “Dr. Scott Stevenson” She replied. Then we went upstairs by using the stairs. In the second floor, me and my mum was finding and observing the names, but the specialists that were looking for wasn’t there.  I noticed that me and my mum was getting lost and neither of us doesn’t know where to go. Then we went upstairs again, looking for the name and finally found the name. Near the lists of the names is a door. We went inside and saw someone in the hospital counter. “Excuse me, can you please tell me where Dr. Scott Stevenson is?” Mum asked, then the lady inside the counter replied back, “Yeah, just keep on going straight then turn left, then you will see another counter, then you can ask the lady over there, about your appointment with Dr. Scott Stevenson.” Mum thanked the lady in the counter, furthermore we went straight then we took a left, then we saw the counter. Mum asked about my appointment and the lady in the counter told us to took a seat over there. Seating in a couch was making me comfortable. A few more minutes past when I suddenly heard my name. My heartbeat went as fast as a cheetah. “This is it” I said to myself getting up the couch. Being nervous and being tensed is really bad for my health that’s why I took a deep breath and carry on walking towards Dr. Scott’s room. He told us to seat in the chair, then he started asking me questions like I’m having an interview. The interview was all about my nose. To be honest I’m having some issues about my nose, something like having a block nose everyday. I think it’s because of the season or maybe because of my hayfever, but it wasn’t. The specialist told me to seat in the comfy chair over there. I laid down, then he took his flashlight and equipment. Then he started checking  my ears, eyes, nose and my other senses. After that, he told me again to seat back in the chair (not the comfortable one). Then he started explaining the issues and why the medicines that my usual doctor gives doesn’t work anymore. It is something about the cartilage or something. He said that it went bigger. Then he suddenly, came up with a silly plan. “We would need to have an operation for her” he said. “What the!” I was outrage. I feel like I wanna faint. I felt like this would be the end of the world for me. I felt confused and felt horrified. Why the heck do I need an operation? I asked myself. Oh well. I wasn’t even listening to the specialist any more I was just daydreaming of what will happen during the operation. My mum was asking some questions like “Would this be a risk for her?” I was just out of my mind that I couldn’t even think. Then after the conversation between my mum and Dr. Scott, all of us went outside the room. My mother checked with the counter and asked “Would there be any cost for the operation?”.“It depends” the lady in the counter replied. Then Dr. Scott gave my mum a receipt and schedules of his operation so we can make an appointment as soon as possible. After that me and my mum went down the building. My mum called dad using the phone and told him to pick us up. After a few minutes, my dad and my siblings arrived with the scent of the food. When we both got in the car, I spotted my siblings drinking some drinks, then I asked “Did you guys went to Mcdonalds” I asked with a sight of confusion. They answered “yes”. I sighed dramatically. Going to the doctor was all fine, it didn’t turn out the way I wanted, at least when getting an operation can make my life better.

Final: 9th of October, when it all happen. This is the day when I felt scared and unfamiliar. They say that having an appointment in that place would go fine, but for me it went unusual.

- What are Geologic Time Periods?

The geological time is a system of chronological measurement, that relates to stratigraphy time. It is used by geologists, paleontologists, and also other Earth scientists to describe the timing and relationships between events that have occurred throughout Earth’s history.

- Name them

- Why are they important to scientists?

Time is a very important in geology, this is because the exact timing of spatially separated events allows us to reconstruct the surface and surface conditions of the ancient earth. Scientist are discovering more about time and also geology that's why this is important.
