Predictable Exposure Difficulty:
My assignment shot requirement state clearly not to
have any light source in the image. Like the rest of
my requirements, it’s meant to keep you out of
predictable difficulties.
Getting a light-source in the image makes getting
the correct exposure chancy at best. Few students
luck out but most don’t. And the Histogram
evaluation also becomes far less predictable.

Light-Source Shot:
When shooting the
light-source shot, it’s
impossible not to get
the light-source in
the image. And, as
expected, the exposure easily becomes an issue.
Shot 1: The sky is well exposed but the foreground is not.
Shot 2: The shadow area is well exposed but the sky (the
subject) is blown out.

Light Source: Extreme Itonal range
Digital
HDR: High dynamic range
HDR means that the tones
in the image exceed the
sensor chip’s capability to
record all the tones.
So, if you record the light tones (sky) properly, the tree
and the buildings are rendered black to near black. Or
the shadow tones (buildings) are properly rendered but
the subject (sky) is over exposed (blown out).

HDR: Dealing with it
One marginal solution for dealing with HDR
is lowering the camera Contrast setting. If
the example shot were to be reshot with a
lower camera Contrast setting, the trees
and the light roof patch would have shown
more detail.
A much more effective solution is to activate a special circuitry
in the camera to deal with HDR. And all DSLR sensors are
larger making them better able to deal with HDR. But HDR is
still a problem with all digital cameras.

I ’Optimizer’
Sony Solution: HDO
Sony’s Alpha series DSLR cameras has been
breaking new grounds and winning awards for a
number of years. Alpha 100, Sony’s first DSLR,
made a big hit by being the camera of the year
for several years in a row.
One of it’s award winning feature was called
HDO. The O stands for optimizer. And it’s been
getting better ever since.

Light Source: Sony IS I
Digital
Sony IS (Image Stabilizer):
Sony was the first to put the IS into the camera body
instead of the lens. They may still be unique in that
regard. Putting the IS in the body allows any lens to
acquire IS capability. And that is a major deal.
Sony has a huge legacy of relatively inexpensive
lenses from the Minolta/Konica line of cameras. Any
of them will be IS capable with the IS in the body.
Sony also carries high end Zies lenses which also
benefits from IS without costing more in price,
weight, and power consumption.

Which is Better:
Of the two, the first
image gives better
information about
the light source.
On the second,
Since the light-source is blocked up, it is not clear whether
the light source was just skylight , cloudy, or mixed like
the first.

Take 2: Work around
No need to rush out and get a DSLR with better
HDR handling capability. Just take 2 shots. One for
Sky and the other for the shadow area.
Doing so makes sense because both the Sky and
the Shadow area can contain lighting relevant
information.

Incorrectly Exposed:
This is Toy’s Light shot. It’s very under exposed. His assignment
shot ‘Lonely’ was also seriously under exposed. And that is a
pattern. If the pattern repeats in other situations, it becomes
predictable.
A predictable pattern can be countered with a predictable EC bias
settings. For instance, Toy may try applying an EC +1 to +1.5 bias
on the next shot.

Assignment Lighting:
Photography: Drawing with light
Next to the story, being aware of your light source
and its end effect on your subject and scene is a
critically important skill for you to master.
Most of you are shooting the Light shot at the end
as an after thought. Start shooting it at the
beginning of your shoot. This will force you to
observe the lighting first.
You might also have to shoot it at the end in case
you have changed your shooting position or angle.

Special Information:
Earn Bonus Points:
Do an in-depth study and report on Light and
Lighting. Turn it in as a 1 page report with 3 to 5
paragraphs with individual paragraph headers.
Use any Library or go online to research world
wide. Start at dpreview.com.
Done right, it’ll be worth bonus points. Done
without depth, will not earn bonus points.
Any bonus point attempt must be approved in
writing by me.

Summary Slide: 1
Beyond the Point: Of no return
We have now moved beyond the halfway point.
And all of you have had several 1:1 sessions
with me on your assignment images and class
standing.
Therefore, I expect you to know just about
where you stand and what area(s) needs work.
If you continue at the same level of assignment
and class performance, expect your grade to be
about what you saw during our 1:1.

Summary Slide: 4
Rather Than Grade Focus: I Hope that…
Your main goal is to learn how to tell a powerful
story through Image Making. In that endeavor,
you learn about aperture, shutter speed, color,
focus (sharpness), composition, photographic
design, and drawing with light.
