This example is of a diatom microfossil in diatomaceous earth. Top left are the three source image slices at three focal depths. Top right are the contributions (black is no contribution, white is full contribution) of that focal slice to the final "focus stacked" image. Bottom is the resulting focus stacked image with an extended depth of field.

Diatomite rock sample from Sisquoc Formation Scanning electron micrograph of diatomaceous earth. Diatomaceous earth (/ ˌ d aɪ. ə t ə ˈ m eɪ ʃ ə s / DY-ə-tə-MAY-shəs), also known as diatomite (/ d aɪ ˈ æ t ə m aɪ t / dy-AT-ə-myte), celite, or kieselguhr, is a naturally occurring, soft, siliceous sedimentary rock that can be crumbled into a fine white to off-white powder.
One of the most famous uses was by Alfred Nobel who developed dynamite; a mixture of diatomaceous earth and nitroglycerin. This image of diatomaceous earth particles in water is at a scale of 6.236 pixels/μm, the entire image covers a region of approximately 1.13 by 0.69 mm. Reason
Of these, diatomaceous earth in particular has seen a revival as a non-toxic (when in amorphous form) residual pesticide for bed bug abatement. While diatomaceous earth often performs poorly, silica gel may be effective. [75] [76] Basket-work panels were put around beds and shaken out in the morning in the UK and in France in the 19th century.
The Chinese government has a released a series of stunning high definition images taken from space by a state-of-the-art satellite. China's Gaofen-1 satellite was launched in April 2013.
Diatomaceous earth filtration is a special filtration process that removes particles from liquids as it passes through a layer of fossilized remains of microscopic water organism called diatoms. These diatoms are mined from diatomite deposits which are located along the Earth's surface as they have accumulated in sediment of open and moving ...
