The Camera


                                                               The Camera
               
1. The "camera obscura" effect is an optical effect which inside a completely dark room, a small hole is made. Through the hole, light is focused and the optical effect is projected upside down on the opposite wall.
2. When Isaac Newton and Christian Huygens perfected the understanding go optics which helped getting to the modern camera.
3. In 1827, Joseph Niépce added film which pretty much created the modern camera.
4. Modern Cameras still use film and has the same basics except Niépce camera took over 8 hours to expose.
5. digital cameras use electronic sensors called a CCD. to capture a photo. The photographs are stored on the reusable computer memory.
 
                                                                Camera Modes  

6. The difference between the Auto Mode and the Program Mode is Auto Mode in which the camera completely controls the flash and exposure. In Program Mode, it has automatic- assist, where you just point and shoot and you can usually control the flash and a few camera settings.
7. The portrait mode is used for attempting to blur out the background, and the camera trys to use the fastest lens setting.
8. The sports mode is used for freezing motion, and the camera trys to use the highest shutter speed possible.

                                                                 The Half Press  

9. You should a half press on the trigger button because it gives the camera faster response times, more control over the focus of the picture, and gives a better composition.

                                                               Controlling Flash 

10. The symbol means disabled flash and is used for not using flash to make a picture possibly more dramatic.
11. This symbol means auto flash and is used to enable flash to give the photo more light.

                                                            Introduction to Exposure

12. If there is too much light, your photo will be washed out.
13. If your photo doesn't have enough light, your picture will be too dark
                                   
                                                                The Universal Stop. 

14. A "stop" is a relative change in the brightness of light.
15.  The new planet would be 1 stop brighter.
16. It would be 2 stops brighter.

                                                             Shutters and Aperture

17. A longer shutter speed gives more light to the picture.
18. A shorter shutter speed gives less light to the picture
19. The aperture controls the amount of light reaching the film, since it acts as a pupil.
20. You can increase the amount of light by making the Aperture have a larger opening.

Academic shoot

1. Avoid mergers 2. The subject of my photo is the two boys in the back writing and the boy scratching his head. the merger is the blonde boy in the bottom of the photo. 3.I think it is fairly clear that the 3 boys are the main subject with the blond boy as the merger. 4. If people couldn't easily tell I could have gotten closer to the boys and maybe have made my subject smaller and done 2 boys instead of 3. (and a half) 1. Rule of thirds 2.The subject of my photo is the girl reading her book 3. It is pretty clear whom my subject is since she is what the photo mainly focuses on. 4. If it isn't clear, I should have gotten closer to her and crop out the boy on the far left. 1. Simplicity 2. The subject of my photo is the piece of art. 3. I think it is pretty clear since the main thing in focus is the drawing. 4. If it isn't clear I should have used a high aperture setting to blur out everything except for my main subject. 1.balance 2. The subject of m...

Academic shoot reflection and critique

1. Some of the challenges I faced while trying to follow the rules during the shoot was, that it was hard to find all of the rules. I thought it would be easy but it was actually kind of hard to find some of them. Not only that but as a photographer, i personally like more of a clear background but you can't do that with academic shoots since their are people everywhere! Lastly, their was not the best lighting since it was in a classroom. 2. I thought the most about the rules since that was what we were out there to do. I also focused on flipping the camera horizontal for some photos that I needed a closer and more full- body picture for. 3. If I could do the shoot again, I would try to get closer to some of the "subjects" to make sure it focuses only on the things I wanted in the photo. 4. I would keep my balance photo, my lines photo, and the simplicity picture. These are my favorite photos since I feel that they are good examples of the rule. 5. I think that the ne...
