I am given a task to help a non-profit come up with their inventory of roots and plants that are used for medicinal and food purposes in a community. Below is what I have in mind, which begs your suggestions: I plan to set up a photo stand myself. I have a Manfrotto 055 x-ProB which allows the central bar of the tripod go horizontal. I will also prepare a dark background 12"x12" floor and a glass platform 3" or so above this black background to avoid bringing the texture of the background to the images. (Got the idea from http://wyomingnaturalist.com/plant_blue.html). I will either use two Nikon SB-800 for lighting, or set up two table lamps as permanent light sources. I can consider getting cheaper flashes to leave them with the non-profit when I am done. Finally the most important question: Which lens to get? Our budget will be limited but if I am keeping this lens, I can spare some money to a total of around $800 (having the possibility of a used Nikon 105mm in mind). The inventory will be used academically and in a museum type of display possibly. So the photos will need to allow recognition of the plants/roots.
