First faltering attempts at macro photography.

1. Macro Photography

2. First attempts at Macro
Photography.
Trial One:
17-40mm Lens
with
36mm Extension Tube

3. 2 mm Wide
Individual False Mallow Seeds

4. 1 cm Diameter
False Mallow Seed Head

5. 8 mm Wide
Nerite Shell

6. Trial Two:
70-200mm Lens
with Stacked
36+20+12mm Extension Tubes

7. Lens is Parallel to Surface

8. Bermuda Sand Sample

9. 2 mm Wide
Individual False Mallow Seeds

10. 1 cm Wide
False Mallow Seed Head

11. 1 mm Wide x
1.5 mm Long
Shells from Fiji Sand Sample

12. 8 mm Wide
Nerite Shell

13. Preliminary Conclusions:
It appears that in order to do good macro photography, I am
going to need better lighting. With better light, I can get
better depth of field which means sharper images.
As far as the lens setups are concerned, the 17-40mm lens
with the 36mm extension tube gives me large magnification
at a short working distance. The 70-200mm with 68mm of
stacked extension tubes provides increased working distance
at the loss of magnification.
Advice would be appreciated...
