The camera exposure mode was set at Manual: ISO 640, 1/250s - f/3, -1.0EV. Since the output of both flashes were controlled automatically using iTTL. It was way too confusing to use automatic exposure for the camera also. When using the iTTL flash, the camera is almost always set at manual.
Setting the Built-in flash Mode at "--" let the Built-in flash only used as a trigger for the other two remote flashes. But in reality, the amount of light coming out from the Built-in flash can still influence the lighting. Nikon makes a small gadget SG-31R that blocked the white light from the Built-in flash completely and only let the infrared light out to trigger the remote flashes. A nice gadget to have, should buy it next time when I will be in the US.
I can see all three flashes worked as they reflected as three spots on each of the two round balls. The left side flash is brighter than the right side flash. The built-in flash that used to trigger the two remote flashes can also be seen. I removed the three spots on each of ball using Photoshop. An umbrella for each of the flash should solve the problem. Over all, a nice exercise!

Huntley Meadows was not too far away from my daughter's home at Falls Church, VA. I went to this place earlier with my D700 and 28-300mm lens and got some descent images. The Spring was just starting with all the colorful new leafs coming out. The second time I went, I was fully equipped. I have Gitzo GT2541 tripod, RRS BH-40 LR ballhead, Nikon MC-30 trigger release, HOYA CIR-PL polarizer, D700 and Nikon 70-200mm f2.8 VRII lens. The images were taken either with mirror-up or Lv.
Photographing with Lv was some inspiring experience. During the focusing process, I enlarged the focusing area on the LCD screen and could see the detail of the area that the camera was focusing and the camera movement, only till the focusing is 100% sure and the camera movement is completely steady then I released the trigger.
I took three photographs to compose the above panorama image. I did not pay too much attention to the nodal point of the lens. The foot of 70-200mm is probably very close its nodal point already and at 70mm or above, I usually have very little distortion when stitching the images together in Photoshop for panorama.
The only processing that I did to the RAW image is to use the "Landscape" setting of Picture Control in NX2. The sharpening is at default of "4", which is more than enough for the image. I used to set the sharping at 7 and even use Unsharp Mask to further sharpening the image. A good lens and proper technique produced sharper original image.
The panorama image at 300 dpi is 9 x 32 inch in size and the TIF file is 144.2 MB. I printed it out by a local photofinishing shop near Washington, DC using Fuji Frontier printer on 10x30 paper. Very nice, and worth all the effort! The photographs that were taken during the previous occasion using 28-300mm lens offhand have no comparison.
However, panorama image does not show too well on the web. Here is another image at standard 4x6 portrait format, hope the quality of the image can be better experienced.
