HDR IMAGES
Assignment Due:
B day: Tuesday Dec. 4th
A day: Wednesday Dec. 5th
[If you want the extra credit it MUST be in on the day it's due]
Assignment
Take photos in 2 different locations. You will have 5-7 different exposures of the same image in each location giving you 10-14 photos total. Make sure to use a tripod or set your camera down on something that will not move. If you move while taking your different exposures your HDR will not work! [for help on taking photos scroll down and read for further instructions]
Extra Credit
This is your only opportunity for extra credit this semester!!! If you need it take advantage! Your extra credit is taking extra HDR images and turning them in as a final product. You can take up to 3 extra HDR image giving you a total of 5 differnt locations and a total of 25-35 images.

What is HDR?
High Dynamic Range photography is a set
of techniques that allows a greater dynamic range of exposures (the range of
values between light and dark areas) than normal digital imaging
techniques. The intention of HDR is to accurately
represent the wide range of intensity levels found in real scenes ranging from
direct sunlight to shadows.
How do I start?
1. Use a tripod,
perfectly stable, with a cable release if possible. Make sure nothing is moving in the scene and
that you do not move. Merging your
exposures only works with different exposure of an identical scene. They will
not line up accurately if you or something in the scene moves.
2. Figure out what
your aperture and shutter would be for an average exposure. To do this, put your camera in P mode, point
at the scene and press half way down on your shutter release. Notice in your viewfinder it will recommend
an aperture and shutter to be used for an accurate exposure.
3. Set your camera
on Manual, Select ISO
(usually 100 ISO on tripod), and set your aperture and shutter speed according
to the cameras recommendation from step #2.
Take your first shot.
4. From here you
will take several more exposures of the scene by only changing your shutter
speeds. Do not change your aperture
(f-stops) because doing so will change your depth-of-field. Changing the shutter speed will give you the
largest range in shadow and highlight detail.
*If you do not
have a Manual setting on your camera, use your Exposure Override function on
your camera. Ex: (0, +1, +2, -1, -2)
