According to Steadman 2001(4), this is the connotation of camera obscura according to the astronomer Kepler. Usually, the typical image of the camera obscura is very thin. As a means of sharpening the image, the hole should be very small to limit the light going through. Moreover, there should be a very bright light striking on the outside scene. For one to see the image opposite the hole clearly, he has to wait for some time for his eyes to amend (Steadman 2001). According to Renner (2009), an example of camera obscura is the sun’s illustration, which is usually very visible. This can be observable in rooms that have small openings in the roof and the sunrays go through the openings. The same can happen when the sunrays penetrate thick canopies. Aristotle viewed the sun’s image that was formed under a tree changing into crescent shape when there was an eclipse. From this, he predicted a practical use of the camera obscura in the 17th century, and this entailed viewing solar eclipses while preventing eye damages (Renner 2009). According to other astronomers, camera obscura is an epistemological model. This is because it changes any random data into a stable vision whose apparatus corresponds to a single, numerical definable point making it easily utilizable regardless of the technical concerns that might be emergent. ...
