How to distinguish various microscope photos in cell biology?

Look at the scale, color, three-dimensional sense and background of the object to make a comprehensive judgment. The main body is colored, and a picture can hold many cells. The image looks very flat, which is a bright field shot by an ordinary light mirror and a color camera. There are many cells in a field of vision like this, but you can see the difference between light and dark, and even have a lost three-dimensional sense (only a little), but there are not many colors, which is the difference between ordinary mirrors and color cameras. If the picture color is only gray, it is a monochrome camera. In contrast, differential interference microscope (DIC) has a strong stereoscopic effect (left phase difference and right DIC), but it looks quite flat on the whole (mainly limited by the thickness of the imageable sample). Generally speaking, the magnification of microscope shooting is 10X? 40X？ 100X, you see how many pixels the object in your picture corresponds to, you probably need to know how big the object you see, and then what is the microscope magnification you use for inverse calculation. If you don't know what size you are looking at and how long a pixel of the picture you see represents, it is difficult for you to know the magnification of the picture you took. If the tumor cells are photographed, the diameter is about 10-30 microns. In the management information system, the physical model describes how the object system "does" and "realizes" the physical process of the system. Generally speaking, the structure of data warehouse adopts three-layer data model, namely conceptual model, logical model and physical model. Physical model: the physical distribution model of data warehouse is constructed, which mainly includes the configuration of software and hardware, resources and data warehouse mode.
