Just finished my new Muro Via Torsione in Amboyna Burl. These two shots were taken with the Nikon 60mm f/2.8g Micro lens mounted to a D90. Without a doubt my favorite lens!


Thanks for the kind words guys! I thought they turned out nice too. Dave, I was about 6 to 8 inches from the tip of the pen in the second image. In the first one probably 10 to twelve inches. I looked at the camera data for the second image, it was 1/1.3 seconds @ F/36 which is as small as the lens will go. The Exposure Value was -0.7. As far as the light box Glenn, its two diffused lights on the left and the right side. I set the camera timer to 5 seconds, and move the right light around, including overhead at times to get the lighting where I like it. I can play with the lights while the camera is counting down. The second image is a little tricky because of the weirdo angle, but I want to show the curves of the barrel.. I think I'm going to start shooting more in RAW mode too. I ran a few images through Nikon NX and they look even better uncompressed. You could actually see the sharpness change. Interesting! Love this stuff!!And Scott, I usually let the camera autofocus, but if I move away from F/36 to say F/14, I will move to manual focus. The camera seems to want to focus on weird spots.. I like to deside were and what to focus on in that situation.

Correct! If your target format is jpeg, then the primary difference between shooting in raw and jpeg is that the camera's firmware is doing the conversion for you (according to its recipe) instead of you doing the conversion in post-processing. As long as you're satisfied with the job the camera does, there's no real advantage to shooting raw. If you're producing a photo that you will share on the web (such as on penturners.org), then resizing to 800x600 is going to lose way more detail than the raw-jpeg conversion did.I'm not really sure its worth taking the shots in RAW as they will then need to be converted into a JPEG before posting them up online such as IAP or Facebook or a website for that matter.
There are two primary differences between the D90 raw format and jpeg format. One is color space. The D90 raw format saves 12-bits of data for each color channel for each pixel whereas jpeg only saves 8. The other difference is compression. The raw format is uncompressed whereas jpeg uses a "lossy" compression scheme. The compression rate is variable, and the more you compress, the more color data you lose. The color loss becomes visible as pixelization, posterization, and loss of sharpness (aliasing).I did find it interesting that I was able to actually see a change in the sharpness of the image when I checked the same image, .NEF file type vs the .JPG image. The file size difference is huge too. The RAW .NEF file is around 9 Megs vs the .JPG file size around 4 Megs. Alot of data compression is going on there! I suppose if I were going to print a poster size image of my pen it would make more since to work with the RAW image file.
