The first session today was on Forest Foods and Pharmacy led by Ila Warren and Brittney Hughes (Naturalist, DeSoto State Park in AL). We met at Metcalf Bottoms and walked to the Greenbrier School. Here are things we saw and info about some of them.

1. Witch Hazel (by bridge and water) - astringent, used for water dowsing; loves its feet in water, seed pods burst, beins are not symmetrical.

Our next session was on Wildflower Photography using an SLR camera. This was led by Jack Carman ( author of Wildflowers of Tennessee) and Bob Hutson (co-author of Wildflowers of the Great Smoky Mountains). We were also in their class on the first day and this really added to what I learned on the first day.

1. Focal length divided by camera’s multiplication factor (Nikon = 1.5)
2. Manification talked about in terms of life size: 35mm =1x1.5=life size; ¼ life size = 4x6”
3. SLR shopping - look for Depth of Field Preview, Live View, manual or aperture priority, cable release, mirror lockup, Nikon or Canon

1. macro lenses are the Cadillac of photography; life size without accessories; 100mm or 180 mm-200mm which is better; goes to life size but not as flexible as a soom lens for other uses and cost.
2. Zoom Lenses - work well for flower photography, use a diopter or extension tubes for magnification beyond ¼ life size; 70-200mm or 70-300mm works well
3. Diopters - fits in front of lens, 2 elements are high quality; magnification is the focal length of lens divided by focal length of diopter; positives (no light lost, low cost); negatives (minimum optical degradation)
4. Extension Tubes - hollow tubs between lens and camera; magnification is length of tube divided by focal length of lens; Positives (no optical degradation and relatively inexpensive); negative (loses light)
5. Multipliers - 1.4x (1 stop) or 2x (2 stop) are best; fits between lens and camera; increases focal length but maintains the original close focusing distances; positive (longer focal length); negatives (some optical degradation and major light loss; should not be used with zoom lens)

1. Tripod - goes flat to the ground; Eye height without use of a center column; minimum 4 lbs if made of carbon fiber ($$-$$$) or 5 lbs. if made of aluminum ($); legs move independently; 3 secions stronger; Brands - Bogen Gitzo, Induro, RRS
2. Tripod Heads - ball head most commonly used; camera placed and locked by a single knob, quick release; ara - Swiss
3. Cable Release
4. Angle View Finder
5. Level
6. Polarizer
7. Dark Cloth
8. LCD Views - old slide fild , 4x Loupe, Hoodman 1x loupe; newer model collapses
9. Plant holder (pipe cleaners, ties)
10. Commercial stakes to hold accessories
11. Camera cases

Electronic Flash
1. Use standard TTL flash unit
2. Flash used mostly as fill with a flash compensation setting of 2 stops
3. Used with a diffuser

Batter Powered LED Lights
1. See results before you take the picture
2. More control than reflector
3. Video broad light like a reflector
4. Flashlight, spotlight, or special effects
5. Video Lights have more color cast
6. Correct with gel or filter provide
7. Flashlight has greater color cast
8. Inexpensive video lights ($40); available such as CN-160 from Amazon
(Note: Get Light Source in close light up subject not the background.)

1. Rain umbrella - 36 inches
2. Collapsible Translucent - 32 inches
3. Photographic umbrella - 60 inches

Shading Tools - Black piece of cloth over umbrella

Depth of Field (DOF)
1. Use manual focus
2. Depth of Field - difference between the closest point in acceptable focus and farthest point in acceptable focus.
3. DOF is a function of
4. The magnification of subject - mag. Increases, DOF decreases
5. F stop - f stop increases, DOF increases
6. DOF is not a function of lens focal length
7. Maximize DOF
8. Camera back should be parallel to the plane of your subject
9. Selective focus

Depth of Field Preview
1. Lens is normally at its max opening, min. DOF when you look through view finder
2. Use DOF preview button to stop the lens down to the picture taking aperture
3. DOF preview with live view
4. Focus with live view

I had a great time at the Spring Wildflower Pilgrimage 2013. If you have never been to it, I highly recommend it! Maybe I’ll see you next year!
