Pictures taken using this lens:

Hocking Hills Lower Falls by Jack Everetts

Additional data:
Camera: Praktica IV FB
Shot on: Fujichrome Provia 100F

This particular photo is of the Lower Waterfalls located in the
Old Man's Cave area. The camera is looking East, so the
Falls are facing South, We arrived at this point about noon,
and I set-up the tripod and mounted the camera and lens on
it. The weather was extremely overcast that morning, but
the sun did come out for just a little while: you can see the
sunshine on the rocks just to the right of the falls and on the
falls themselves. Also, this is located down in a gorge with
high rock walls all around,

After scanning the transparency, I used Adobe Photoshop
Elements; the image has been cropped slightly. An incident
lightmeter determined the exposure, and a slow shutter
speed was chosen for the effect on the moving water.

Scioto River by Jack Everetts
No.1 No.2

Additional data:

Camera: Praktica V FB

Shot on: Fujicolor NPC 160

Accessories used: Along with a polarizing filter, Adobe
Photoshop Elements were used as well.

It (no. 1) was taken November 3rd, 2002 in the morning
between 8:45 and 9:30 AM. The sun was just high enough
to strike the trees on the west bank of the river, but the
sun's direct rays didn't hit the river itself. Additionally, a thin
layer of haze or fog hovered just over the water - the
outside temperature was chilly that morning. After the sun
rose higher, the reflection of the trees in the river completely
disappeared as did the haze.

Metering techniques: and incident light reading taken
directly of the bright sunlight just before walking down to
the riverbank, so the exposure is based on the reading off of
the bright sun's rays plus 1.5 stops for the polarizing filter.
