1
Introduction to Plant Photography
2
Purpose Being able to use photographs to identify the species adds validity to the data collected and entered into the SE-EPPC EDDMapS
3
Photography Learn the diagnostic characteristics of the invasive species Capture them in enough detail to make identification possible –Usually will require a series of photographs
4
Common Characteristics Used for Identification Flowers Seeds/Fruit Garlic MustardBicolor Lespedeza
5
Common Characteristics Used for Identification Nepalese BrowntopEnglish Ivy Whole PlantGrowth form
6
Common Characteristics Used for Identification Woody Plants - Leaf arrangement Opposite Chinese Privet
7
Common Characteristics Used for Identification Woody Plants - Leaf arrangement Alternate Oriental Bittersweet
8
Common Characteristics Used for Identification Woody Plants - Leaf shape Simple LobedCompound Amur HoneysuckleNorway MapleTree-of-Heaven
9
Common Characteristics Used for Identification Unique Features CogongrassTree-of-Heaven Pointed Rhizome Glandular Notch
10
Common Characteristics Used for Identification Unique Features Yellow Star-thistleAir potato Thorns Bulbils
14
General Principles of Photography To reduce shake, use a tripod when possible Take multiple photographs of the same subject and choose the best one Use the highest resolution and best quality images available with your digital camera Images uploaded to system in JPEG format
17
General Principles of Photography Position yourself so that the sun is over your shoulder for the best light (Frontlit image)
18
General Principles of Photography If the sun is behind the plant (your are looking into the sun) then details of the plant may be lost in the shadows (backlit image)
19
Frontlit image Backlit image
20
General Principles of Photography A flash can work when the natural light isn’t enough or coming from the wrong direction Try adjusting your flash intensity
21
Low intensity flash Removes shadows and illuminates detail without “washing out” colors
22
Focal Plane A plane parallel to the face of the camera’s lens in which everything is in focus (aka depth of field)
23
Focal Plane
25
Common buckthorn
26
Camera Settings Automatic settings are usually adequate Manual setting options –Shutter Priority Hand-held situations Long exposure (with tripod) –Aperture Priority Depth of field In conjunction with macro –Macro (close-up)
27
Aperture (F-stop) The hole in the lens through which light passes (represented by an F-stop value)
28
Aperture (F-stop) Small F-stop numbers = large aperture = shallow depth of field Large F-stop numbers = small aperture = large depth of field
29
Aperture (F-stop) Adjusting the aperture size can increase or decrease focal plane depth Small F-stop number
30
Aperture (F-stop) Adjusting the aperture size can increase or decrease focal plane depth Large F-stop number
31
Shallow Depth of Field Large Depth of Field
32
Japanese Honeysuckle
33
Macro Fine detail Close-up
35
Photographs to include The form allows five images to be uploaded with each record entered –Identification images –Infestation/Landscape image
