Transcript of Depth of Field

Long Depth & Short Depth of Field
Depth of Field
Aperture is...
Aperture is the size of the lens opening when an image is taken
When you hit the shutter release button on your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you’re wanting to capture. The aperture that you set impacts the size of that hole.
Camera Operations
Shutter Speed is...
Shutter speed is the amount of time that the camera shutter remains open
In film photography it was the length of time that the film was exposed to the scene; similarly in digital photography shutter speed is the length of time that your image sensor ‘sees’ the scene you’re attempting to capture.

Long Depth of Field = Long Range of Sharpness
Long Depth of Field
Short Depth of Field = Small Area/Range of Sharpness
Short Depth of Field
-You will be focusing your attention towards

short depth of field!
-To fulfill the requirements of this project you MUST have a collection of Short Depth of Field images that exhibits
interesting textures.
Short Depth of Field= focus on macro images
When looking for subjects, look for texture
Capture
15 images
!
Project 5: Depth of Field
-Depth of Field refers to the RANGE OF DISTANCE that is SHARP in your photographs
-Depth of Field always exists in your images, the type simply changes according to the camera settings you use.
What is Depth of Field?
Top to Bottom or Foreground-Middle-Background
remains sharp and in detail
When adjusting camera modes, use the APERTURE PRIORITY mode so you can set the camera to a SMALL lens opening to increase the depth of field
You can also use the LANDSCAPE mode to give yourself a large range of sharpness as well.
Shallow Depth of Field means your camera has focused on one area or one object.
To set up the camera mode, choose Aperture Priority again, BUT use a large aperture setting instead of a small one.
You can also use the Macro setting on your camera to adjust the focus area on your camera as well.
Texture
Texture is the feel, appearance of feel, or consistency of a surface or a substance.
Physical Texture-
The ability to feel a texture on a surface of an object.
Implied Texture-
The ability to imagine the texture of a surface from a
2-dimensional representation.
Project 4: Long Depth of
Field Landscapes
The second half of the Depth of Field unit focuses on long or great depth of field. Which means your images will be extremely detailed.
-> Focus on interesting landscape compositions (ie. barn in a field, skylines, sunset, forest, main street of a city)
-> Keep in mind the elements of good composition!
-> Capture a collection of 30-35 images where the subject varies!!
-> Half of the images turned in will follow an HDR
tutorial. The other half will be edited using a
tutorial you research and use.
What is HDR?
A set of techniques that allow a greater dynamic range between the lightest and darkest areas of an image.
This wide dynamic range allows HDR images to more accurately represent the range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight.
Translation...
HDR gives images a very unique look that increases values and detail.
