Digital Photography I
Close Up/Macro Photography:
Close Up/Macro Photography:
The compact digital is engineered to shoot People standing about 8’ from the camera. It’s also meant to shoot Scenery with the focus set to infinity. Even some of the low end DSLR are designed with the same principle in mind.
*
Specialized Areas:
Moving from normal to specialized areas of photography is like going from one state to another. There is not much fanfare going from Washington to Oregon or from Oregon to California.
*
Zoom Lens: Amazing capability
The compact digital zoom lens is a miraculous technological marvel. It offers capabilities unknown to the previous film generation of photographers.
I normally drive a small 4 cylinder Sedan and my freeway speed is about 55 to 60 mph. On vacations, I often rent 6 cylinder cars. With the extra power, I find myself easily going 70 mph unintentionally.
*
Superzoom Lens: Amazing power
With amazing power comes powerful ways to get into trouble by a press of a button. It can start with the super wide with its high image distortion characteristics.
*
Do It: Turn on your camera and see for yourself
Place a square or a circle shape object near the frame corner. See it skew distort towards the corner.
Fill your frame with a window or window like object. Notice that the window edge is bowed out.

Zoom Lens: Uses

Zoom Lens: Tool use
There is no perfect way to use a zoom lens. But there is such a thing as ‘efficient use’. And that is to balance the different needs:
Increasing or decreasing subject size
Cropping for the right framing
Moozing (going wider) to achieve ‘safety margin’

Close Up/Macro Photography:
Focus-Point & DOD (Depth-of-Field):
Precise focus point and adequate DOF are important to Image Making. It becomes more sensitive an issue when shooting close up shots due to the natural tendency towards shallower DOF.
*
DSLR: Also more critical
Because of physics, shooting with a DSLR takes more care when focusing. The image from a DSLR is also much more detailed showing all the flaws that might be hidden in a compact digital image.
And the compact digital also has a natural tendency for having deep DOF which tends to hide many focus errors.
This needs to be
Stop Down to Increase DOF:
Remember the ‘thumb/squint-view’ exercise we did early on this quarter? That’s where you used the squint-view technique combined with your thumbnail to experience both shallow and deep DOF. Do the exercise again if needed…
*
Class Room: Shooting assignment
Set up a vertical still-life with 7 identical golf ball size objects. Line them up in a straight line diagonally across the image from bottom left to top right. Place the objects at 4, 5.6, 8, 11, 16, 22, and 32 inch positions.
Position the nearest object at the bottom right. Position the last object at the top left. Fill the frame with the story using either the 17 mm for compact or 50 mm for DSLR.
Next slide begins the student example series…
*
Student Example:
The two example images show the exact visual effect when the aperture is change from wide to small lens opening.
This image concretizes the squint-view with thumbnail demonstration that you experienced at the beginning of the quarter.
Focus Point
DOF Rule:
The general rule is to stop down for deep DOF and open up for shallow DOD which is good for selective focus.
The sharp to un-sharp image quality can be seen in both the subject and the black to white line.
This example uses only 5 distance tubes. You will be using 7.
Wide Open Stopped Down
Focus: Near Point
The exact focus point makes a big difference to the illusion of sharpness for the whole image.
An extra tube is being used to indicate the Near Point focus as shown by the red arrow.
Near Point Focus
Focus: Middle Point
When the focus point is shifted to the farther away and up middle point, more of the image appears to be in focus.
Use the Up & Down arrow keys to compare the Near and Middle point images.
Middle Point Focus
Focus: Far Point
This point-of-focus might be the best place to achieve the maximum scene sharpness.
Use the Up & Down arrow keys to compare the Near, Middle, and Far Point examples.
There are many possible conclusion which can be derived from this DOF test shoot series. Try to think of at least 3. And tell me about it in writing.
Far Point Focus
Cameron and his team:
Far Point: Position error:
This shooting assignment is about learning how to maximize the illusion of DOF and sharpness.
Focusing at the end point would not achieve the desired effect.
Be prepared to explain why this would be the case. Try to really see the image to the right which is your biggest clue…
Far focus point?
marker to be better aligned
with the focus point. As the
red arrow indicates, it could
have been moved up in the
set in all the shots.
*
Lab Work: Always do it
Notice that the basic processed image gives far more illusion of sharpness information than the camera original ‘mushy’ image to the right.
Basic Processed Camera Original
Things You’ve Learned: Keep practicing
Lighting – easy to work with broad source soft Skylight. Skylight is heavily Cyan but the Auto WB will neutralize most of that.
*
Good Technique
Focus – maximize the DOF.

Cameron and his team:
Summary: Build good habits
