"The camera, part of the telescope, or the other way round, has a recorded history of use as an indispensable aid in astronomy going back far more than 2,000 years. When the Sun's rays are projected on to a smooth surface through a tiny hole in a dark room or box, the image of the Sun can been seen projected upside down on the surface. Hence the name from the Italian for dark room -
camera obscura.
This idea may have been noticed and made use of for thousands of years, for there are ancient monuments like New Grange in Ireland which make use of a shaft of light from the Sun hitting a particular marked part of a wall at a definite time of the year - the Winter Solstice in this case.
Such a construction was known to have been used by astronomers or astronomer priests or shamans, to fix annual calendars, and to observe the Sun. Chinese astronomers were making records of sun spots, more than 2,000 years ago, as well as of eclipses. They had to draw or paint over the image projected, as it was not until the 19th century that satisfactory methods of preserving the image were developed."
Telescope Revolution of the 17th century
"Johann Zahn designed the first camera in 1685. But the first photograph was clicked by Joseph Nicephore Niepce in the year 1814. It was thousands of years back that an Iraqi scientist Ibn- al- Haytham made a mention of this kind of a device in his book, Book of Optics in 1021. The earlier cameras were incapable of saving the images and were huge in size."
Who invented camera?
After Daquerre (in 1829) improvements in photography took off at a breakneck pace. Does anyone else find it odd that it took less than 100 years to go from Daquerre type photos to what we have now but it took from at least 1021 AD (or 2000 years ago!) to 1829 to be able to capture photographic images rather than just quickly draw them when the sun shone through a hole at a particular time of year?
Since astronomy (or more accurately-astrology) was one of the first known sciences and the elite priestly classes made their living in that mysterious realm, it seems to me that any advantage over your competitors would have been highly sought after and pursued.
As an aside to the origins of cameras and when they were likely produced, the first link (cosmicelk.net) has other useful info regarding some of the questions pertaining to maps we've discussed on this site. May be worth a perusal.
