Camera History

                                      "The Camera"


The effect camera also known as the camera obscura was the first camera the hole acted like a lens, focusing and projecting ligligtht onto the wall of the dark chamber.

 In the 17th century Isaac Newton and Christian Huygens helped men get a step closer to creating the modern camera by perfecting the understanding of optics and the process of making high quality glass lenses.

The parts were a glass lens ,a dark box, and film that created the first successful photograph.

What modern digital cameras have in common with Niepce's camera is that they work the same light passes through the lens, into the camera,and exposes the film, and the results end up being the same you get a photograph.

Digital Cameras capture images with an electronic sensor called a CCD.


                                  "Camera Modes"

Auto or program mode is the default for most modern cameras . The photographer can simply aim, press the button, and almost be guaranteed a great image.

Portrait mode is used to attempt to blur out the background, camera will try to use the fastest available lens setting(aperture).

Sports mode is used to freeze motion, camera will use the highest shutter possible.




                                       "The Half Press"

 You should do  a half press on the trigger button because its helpful in many ways gives faster camera response time , more control over focus , and encourages better composition.

 
                                       "Controlling Flash"

Disable flash- No flash You will use it when there is already  light  available during the capturing of pictures 

Auto flash - Flash on You will use it when there is no light during the capturing of a photograph


                             "Introduction to Exposure"

If there is too much light the picture will be washed out and if there is not enough light the picture will be too dark.

                                 "The Universal Stop"


 A stop is used in every aspect of a photography to represent a relative change in the brightness of light.

Its f4 if theres is 2 suns 
Its f8 if its 4 suns 

                             "Shutters and Aperture"

Longer shutter speed = more light

Shorter shutter speed= Less light

The aperture is like a pupil. YOu can control the aperture by setting the Aperture opening also known as an F-stop.
  
You increase it by opening it up to let light trough.

First Photo-- Best and Worst

Good Picture I think this is a good picture that i took because first of all you can see his face , the picture came out clear, and the picture didn't come out blurry. The things that i did to make it a good picture was that first of all i made sure that he was facing the camera and that he dint move for at lest 3 seconds for me to be able to take a clear picture and not a blurry one. Bad Picture  I think this is a bad picture because you can't see his face at all he is facing away from the camera . The things that i did for this picture to be bad was that i didn't capture his face and i only captured his body.

Avoiding Mergers

This shows a  border merger because the picture cuts off kids in the left and right side of the image. If the kids were to be seen and weren't cut off they would be avoiding mergers. This picture i picked shows the rule of Avoiding Mergers because the image is cutting off kids in the left side and the rigth side of the image this shows that they didn't avoid a merger making this image a Border Merger.

Elements of Art & Principals of Design in Photography

Image
Elements of Art  Line- Lines are marks made by a pointed tool: brush, pencil, pen, etc. Lines can vary in width, direction, curvature, length, or color. Shape - Shapes are formed wherever the ends of a continuous line meet. Geometric shapes such as circles, triangles or squares have perfect, uniform measurements and don't often appear in nature. Organic shapes are associated with things from the natural world, like plants and animals.   Color - Color wheels show the primary colors, secondary colors, and the tertiary (intermediate) colors. They also show the relationships between complementary colors across from each other, such as blue and orange; and analogous (similar or related) colors next to each other such as yellow, green, and blue. Black and white may be thought of as colors but, in fact, they are not. White light is the presence of all color; black is the absence of reflected light and therefore the absence of color.
