If you visit this website

Now if you are old enough you will remember that in the 1960's and 1970's photographs were taken with a camera which had film in it. In fact digital cameras were not available until the late 1990's.
The film from a camera was developed to create a negative, and the negative was used to print a photo. The rolls of film from these missions were developed and printed when that particular mission returned to earth. And the best of them were made available to the public at that time - on television, in magazines and in books.
Also at the time the best computer graphics were along the lines of this 1975 rendering of a teapot - this one was the best ever produced at that time, and this is the original size it was created.
So there was no CGI used in any of these photographs, it was just not possible to create images with CGI such as the ones from the Apollo mission, and computer photo editing was not pioneered until the 1980's (Adobe Photoshop was not released until 1987), so they were not digitally enhanced or created or "faked" in any way.
These photos were not drawn or painted - grab a copy of "the blue marble" (below) and enlarge it and try to prove it is a painting!! You can't because it is a real photograph, taken on December 7th 1972 from a distance of 45,000 km (28,000 miles) from the earth with a 70-millimeter Hasselblad camera with an 80-millimeter Zeiss lens!!! It has been digitally scanned so it can now be viewed by anyone !!
In the 60's and 70's photos could only be changed by actually painting out any blemishes etc, and this was always so obvious that it was never done for magazine covers or advertisements the way it is today. There is no way that any of these photographs were either manually or digitally manipulated in the 60's or 70's. At that time everyone was fascinated by space and space travel, and anyone my age will remember seeing many of these photos at the time. They have not been created just for the internet !!
Fourteen thousand two hundred and twenty three photographs of proof that man landed on the moon, and the earth is a globe !!
Enjoy them :-)
