Lens Operation and Controls Project

Summary:

In this project, we took photos with different lens. We also did a slideshow that has pictures representing the definitions of the different type of ways to take a photo. Clayton was our photographer but he also helped with the blog and video editing. Avrin found the example pictures and helped edit the video. I researched the concepts and wrote the majority of this blog post.

 

Timeline:

  • Day 1: Researching/Planning
  • Day 2: Photography working w/Macro lens
  • Day 3: Continued work
  • Day 4:Photography working w/ zoom lens
  • Day 5: Continued work
  • Day 6:Photography working w/ wide angle lens
  • Day 7:Continued work
  • Day 8: Start blog
  • Day 9: Continued work
  • Day 10: Finish blog

Terms and Concepts:

  • Depth of Field: The distance between the nearest and the farthest point in an image.
  • Angle of View: How much the lens can see.
  • Wide Angle Lens: Allows the image to capture a far larger area.
  • Longer Lens: Gives the image a narrow angle of view, particularly useful in isolating a subject.
  • Image Stabilization: The techniques used to reduce blurring of the image caused by the movement of the camera.
  • F/ Stop: The f/ stop governs the amount of light allowed through the aperture of the lens in order to capture more or less light, thus making the image either lighter or darker.
  • Lens Speed: The maximum aperture diameter allowed.
  • Iris: Adjustable aperture used to control the amount of light coming into the camera.
  • Focal Length: The distance between the center of a lens or curved mirror and its focus – the equivalent distance in compound lens or telescope.
  • Filters: Restrict the light in a smooth, geometric pattern across the image, use for outdoor landscape photos where the light gradually fades from dark to light.
  • Zoom and Zoom Ratio:  Zooming is the increase of the focal length via the adjustment of the camera. Zoom ratio is the size that the image will be when the focal length is increased relative to what it would be if the whole picture was in view.
  • Manual Focus: Focusing is done by hand.
  • Automatic Focus: Focusing is automatically done by the camera.

Lens:

  • Macro Lens: Macro lenses allow for extreme close-up photography.
  • Zoom Lens: Zoom lenses are capable of increasing the focal length and with it the zoom ratio. Lenses specifically designed for zooming often are capable of higher zoom ratios.
  • Wide-Angle Lens: Wide-angle lenses essentially do the opposite of a zoom lens. Wide-angle lenses reduce the focal length substantially and potentially go below 1:1 zoom ratios, allowing more of the scene to be captured in the final image.

What I Learned:

What I learned was that with different lens, you could achieve a better product depending on what you were trying to capture. The problem we had was trying to find the example photos. Another problem we faced was trying to figure out what to do for the video. We solved it by just doing the pictures that were easy to do and for the video, we did a slideshow.
