The document discusses macro photography techniques and accessories. It explains that macro lenses, extension tubes, teleconverters, and close-up lenses can be used between the camera and lens or in front of the lens to achieve macro photography and increased magnification. A focusing rail is used to precisely position the camera for maximum magnification by moving the camera until the subject is in focus when the lens is at its minimum focus distance. The document provides examples of the effect of these accessories on magnification and includes photos demonstrating depth of field at different aperture settings for macro photography. It emphasizes the importance of a stable platform, manual focus, and understanding depth of field for macro techniques.

2. Macro & Close-up Devices
(and where they go)
1. Lens – macro & regular
2. Between Camera & Lens
– Teleconverter
– Extension Tubes
3. In Front of Lens
– Screw-in Close-up Lens

6. Less Frequently Used
Reversing Ring
Bellows

7. Focusing Rail
For Precise Focus (& Maximum Magnification)
Focusing Rail is used to
Precisely position the camera
in terms of
Distance from the Subject
Maximum magnification (reproduction ratio)
REQUIRES the Lens to be at its
MINIMUM FOCUS DISTANCE
Technique
1. Focus lens to minimum focus distance
2. Bring the subject in focus by –
 Moving the camera
 Until subject is in focus

Maximum magnification (reproduction ratio)
REQUIRES the Lens to be at its
MINIMUM FOCUS DISTANCE
Maximum Magnification Technique
1. Set lens focus distance to minimum
2. Bring the subject in focus by –
 Moving the camera
 Until subject is in focus

10. Hands On Time
Minimum Focus Distance
Distance at which Magnification is Greatest
Maximum is infinity for the two at left
Less than 4 feet for the one above

11. Effect of Various Macro Accessories
On Image Magnification
All images are maximum possible magnification
75-300 @ 300 75-300 @ 300 As on left
+ 1.4 X T-C + Close-up Lens

12. Effect of Various Macro Accessories
On Image Magnification
All images are maximum possible magnification for devices used
NOTE –
• 1:1 means Life-sized
• Life-sized means 1” long subject will fit exactly on a 1” long sensor, for example
• At its maximum magnification
(Substitute 5” for a 4x5 view camera, for example)
1:1 &
1:1 Macro 1:1 + T-C 1:1 + 36 mm tube
12 + 20 + 36 tubes
Example of
Life-sized
Sensor is 1”x2/3”
Stamp is 1” high

13. Can stack accessories
until the lens mount
pulls loose from the
camera.
Note – these 2 have
almost the same
magnification
• Macro lens is not
essential

18. DOF vs. Aperture
105 mm 1:1 @ Max. Magnification
f/5 f/11
Wide open
f/22 f/45
DOF is a fraction of a mm
Centered on focus point
Focus DOF in front of focus point is “wasted” Subject is less
Point than 1” deep
Put Focus Point here
for max “useful” DOF

19. Fixed Aperture; Changing Focus Point
Image Size (& Composition) Changes
1. Focus point distance increases from left to right above
Except for focal point
2. Camera position & all other settings remain constant
Same as previous
slide at f/11 3. NOTE - Subject size shrinks as focus distance increases
Won’t work for focus stacking (combining multiple exposures to increase DOF)
But that’s another subject entirely (& a focusing rail job)

• Stations –
• Canon
• Nikon
• 4/3 & Mirrorless
• Download & Review
• Try your hand using the available accessories
• Ask lots of questions
• Have lots of fun
