Amaryllis Tries To Start A Family
What was, on March 13, 2010 just an amaryllis bulb has grown into a 6 flower metropolis, with an additional two under construction. The pic above is a macro shot of the reproductive area of one of them. The high ISO I used (3200) enabled me to use a a very fast shutter speed, which then enabled me to handhold the camera while using the full 450mm of my lens. I remain impressed with the very low amount of high ISO noise my D5000 produces.
Something that I an really enjoying about my D5000 is that because it is a Nikon DX camera, it’s sensor size gives me a 1.5x crop factor, so my 70-300mm (non-DX) lens is attached, it is a 105-450mm for me. Same for my 50mm f/1.8 prime lens. It is a 75mm when attached to the D5000. Ken Rockwell wrote a great article explaining crop factor, and it is well worth reading. His entire site is actually very informative. Knowing how a lens is going to act on your camera before you buy it can save you some possible buyers remorse later. Full stats for the pic are: 450mm, 1/500th, f/5.6, 3200 ISO
