Aperture and Shutter
Priorities
Oh, no, Mrs. Gilder is allowing you to go
all auto now.
Fear not.
It will all be okay.
Breathe deeply.

Aperture Priority – sets your aperture
while all else goes auto…auto…auto
It’s the Av on the top of your dial.
What does it do?
It enables you to set the aperture
and all else goes automatic. Your
ISO and your shutter goes on auto
mode. But even if you change your
lighting, your aperture stays the
same.
Wait there’s more.
Mrs. Gilder hates auto anything,
but has to teach you this.
Photosearch.com
Aperture, lens length and distance
assignment.
As you know, the lower the
aperture, the lighter the shot and
the lower the depth of field.
But what does that mean Mrs. Gilder?

Checking your knowledge
Why? Because.
Your shot is too light.
What do you do with your ISO?
Shot is still too light
What do you do with your shutter? REMEMBER THE SHUTTER / LENS
LENGTH RULE!!
Results are too light, what would
you do with your F stop?
I knew you’d remember.

Lower the number. Less in focus.
Lower the number, more light.
Items.
Exercise 1.
You are to photograph 3 items.
I have jewelry. Not real, but stuff
to photograph.
Let’s get this auto stuff out of the
way…
Line 3 things up, one behind each
other.
Use the product tent in the studio.
Or go outside and use fill cards.
Shoot in the shade. Use a tripod.
Do not shoot above, instead, be at
the same level as the jewelry so
the back ones go out of focus.
Focus on the front.
This is a depth of field test.

Set your camera at F 5.6, lens
length 55 mm place the upper dial
to AV. Use a tripod and take the
shot.
Next, set your aperture to F-11,
same lens lenght. Dial to the AV
setting. Stay in the same spot.
Look at both photos. What do you
notice?
Same spot, same exercise, change
your lens length to 18 mm.
Sure you’ll get the kitchen sink in
the shot, don’t worry about that.
Set your camera to F 5.6, again AV
setting up top. Take the shot.
Compare that to the first F 5.6
with the 55 mm.
Note the difference.
Now dial up to F 11. Again, AV up
top. Take the shot. Compare that
to the other F 11 taken with the 55
mm lens length.
Go back to 55 mm, F 5.6, AV but
take 1 step back. Again, if you get
the kitchen sink, no worries. We
are looking at depth of field for
those 3 items.
Compare this with the very first
results when you were in closet.
What do you notice?
Go back to 55 mm, now to F 11, AV,
and again, 1 step back. No worries
on the kitchen sink appearing –
look at the depth of those 3 items.
Compare that to the very first
results for F 11.
Fill out the form.
Work as a group.
Shoot full length.
Do the same thing over again, but
now shorten your lens to 18 mm.
What do you notice?
At 18 mm, photograph the 2
people. Have your aperture at F5.6
– hold up the signs but this time
have F5.6 and 18 mm written on
both.
Now do F 11. Hold up the signs,
cross out F 5.6 and have F 11, 18
mm written on both.
Do the same thing again, but step
back, way back and bring your lens
length to 55 mm.
Have both signs say 55 mm, full
length, F 5.6
Take another shot, 55 mm, full
length, F 11
Now do the worksheet.
Shutter Priority
Set your shutter and have your
camera on TV.
The shutter will remain the same
no matter the lighting. Your ISO
and your aperture will change as
the lighting changes.
This is what a wedding
photographer or fashion show
photographer would use all the
time.
Try it so that you know it.
Now take a shot with minimal
depth of field and one with a
higher depth of field. Use jewelry.
A yes
Another yes…
What to hand in?
F 5.6 jewelry, 55 mm.
F 11 jewelry, 55 mm.
F 5.6 jewelry, 18 mm.
F 5.6 jewelry, 55 mm step back.
Worksheet.
2 good jewelry shots, one minimal depth of field, focus on the front, the
other, all in focus. Think of elements of design.
