The image you see in the above was taken by a procedure called Wide Field Imaging. Wide Field Imaging can be accomplished by taking several images of a subject of your own choice. This is generally done to obtain high amounts of detail and the whole subject at the same time. Many photographers tend to use 10x objectives for their choice of magnification so that the images taken say around 100, causing the final compile to have a smaller file size. After obtaining the images, there are several ways to process them, Photoshop, PTGui, or any other panoramic photo stacking application. For the best results have a 50% overlap in subject matter between each image.
The subject is a Nymphaea water lily. The piece above is a Sclereid. It is a type of stone cell. They help support and conduct water through out the plant.
The piece below is a vein. Unlike humans, it doesn’t carry blood. Instead it transports water and food to keep the plant well nourished.
