Lab 5: Noise Reduction


Purpose: to test your in-camera noise reduction settings.
Canon may have low, standard and strong noise reduction settings, while Nikon may have noise reduction for low light and for longer exposure.

1.     Find a low light scene, lit by daylight, that includes color, details, and various textures.
2.     Set your camera to shoot JPG
3.     Put your camera on a tripod (some of your exposures will need to have a longer shutter speed; when dealing with long exposures it is best to use the self-timer so that you are not causing handshake)
4.     Use a sharp aperture for your particular lens. This can be assessed from the lens lab exercise where you shot the targets. If you are not sure which aperture to choose we can look at those images together to assess properly.
5.     Set your camera to 100 ISO (or your lowest available ISO) and take a shot at each of your noise reduction settings. Be sure to take note of your shutter speed and aperture for each shot.
6.     Set your camera to 800 ISO and take a shot at each of your noise reduction settings. Be sure to take note of your shutter speed and aperture for each shot.
7.     Set your camera to 3200 or higher and take a shot at each of your noise reduction settings. Be sure to take note of your shutter speed and aperture for each shot.
8.     Open your images in Lightroom and view the images at 100%
9.     Take a screen shot of a part of each image viewed at 100%
10. Post each image to your blog, including your camera settings (ISO, aperture, shutter speed, and noise reduction setting chosen) Total of 9 images (depending on how many noise reduction settings you have.
11. Write a description of how your camera did with the in-camera noise reduction. Did it loose detail? Would you use your camera noise reduction as a method of decreasing noise? If you have multiple noise reduction settings, which one gave the best results without loosing sharpness?

Due on your blog before the end of class time. 

**Make sure that your images are well exposed. Do not shoot a backlit scene.

Assignment 2: Camera Review

Worth 10%, Due in class on March 1st

Do a 5 minute presentation on your specific camera

  • Make a powerpoint to accompany your presentation. Images you've taken with your camera can be featured. For ex: you could show a zoomed in image that shows how sharp an image is at your high ISO. Also your best images that feature your camera's abilities can be featured. You can also include images of your camera and how the menus are set up.
  • The idea is to sell the class on this camera. Educate others on your camera's strong points. Things to be covered: ISO and shutter ranges, sensor size and type, megapixels, etc.
  • Be honest. If your camera has severe drawbacks let us know about them as well. You could make a pros and cons list. 
Websites such a www.dpreview.com and www.bhphotovideo.com can be used as resources. 

Lab 4: Creative White Balance

1. In the library (in the main area, not in the stacks):

  • Shoot with Auto WB
  • Try your different WB presets and see if any of them correct the colour better than AWB
  • Do a custom WB for this light and then shoot the same scene using the custom WB
  • Submit: 3 images of the same scene. Label which was shot with AWB, a WB preset, and a custom WB.
2. Shoot in an area where there are two different colours of light

  • ex: near a window where you are getting shade light and fluorescent light. Shoot the scene with AWB, shade preset, and fluorescent preset. Submit: these three images. Describe how the colour changes in each image (even if the changes are subtle)
3. Purposefully shoot with the wrong WB preset in order to introduce an overall colour cast to your image. Describe how this changes the feel of the image/scene for the better and for the worse.

Due on your blog before the end of class time.

Lab 3: Lenses

Part 1: Lens Focal length

Photograph two subjects: a still life scene and a scene with people

Still Life:
-Have two or more objects on a table top. One object close to the camera and another further away
-Shoot the scene with your different focal lengths. Make the foreground object take up the same amount of space in each image. This will mean that you need to move closer or further from the subject, depending on the focal length.
-submit 2 or 3 images (depending on your equipment, and describe your equipment at the beginning of your blog post) of different focal lengths, of this scene
-Remark on how depth perception and distortion and amount of background changes depending on the focal length of lens used

People:
-Have two or more people, one closer and one farther
-With your camera on a tripod shoot the same scene with different focal lengths (as many as you have)
-submit 2 or 3 images (depending on your equipment) of different focal lengths, of this scene
-As well as on depth remark on how facial features can get distorted depending on the focal lengths used.


Part 2: Focal Length and Depth of Field

Shoot a subject of your choosing
-Use different Focal Lengths (different parts of your zoom) and shoot the same scene with the same aperture in each image
-Remark on how DOF changes with focal length changes
-Try a wide aperture and a small aperture for this part
-Submit 3 images of the same scene where the same aperture was used and differences in DOF can be seen


Part 3: Test your lens

-At a station set up put you camera on a tripod and make sure that your camera is parallel to the target.
-Test each lens focal length you have. For each lens (or focal length on your zoom) test each aperture (only full stops: 2, 2.8, 4, 5.6, 8, 11, 16, 22) and also test the widest and smallest apertures if they are not full stops (ex: f/3.5).
-So for each lens you will be taking 8 or more images
-If you only have one zoom lens then shoot at the widest, middle and most telephoto focal lengths (so 8 or more images per focal length).
-Submit 8 images and remark on any problems noticed at different focal lengths or at different apertures
