are there any real pictures of earth from space?

I don't mean just seeing the horizon

I mean the whole earth just like in this video at 3:50
This image from DSCOVR , taken from the L1 Lagrange point is my favourite.

"This true-color image shows North and South America as they would appear from space 35,000 km (22,000 miles) above the Earth. The image is a combination of data from two satellites."

not exactly what I was asking for

one photo of the whole earth
The image I posted is from this page:
On February 11, 2015, DSCOVR was finally lofted into space by a SpaceX Falcon 9 rocket. After a journey of about 1.6 million kilometers (1 million miles) to the L1 Lagrange Point, the satellite and its Earth Polychromatic Imaging Camera (EPIC) has returned its first view of the entire sunlit side of Earth. At L1—four times farther than the orbit of the Moon—the gravitational pull of the Sun and Earth cancel out, providing a stable orbit and a continuous view of Earth. The image above was made by combining information from EPIC’s red, green, and blue bands. (Bands are narrow regions of the electromagnetic spectrum to which a remote sensing instrument responds. When EPIC collects data, it takes a series of 10 images at different bands—from ultraviolet to near-infrared.)

how about just a normal photo

like send an iPhone into space and take one picture
When your iPhone takes a picture, it takes in the Red, Green and Blue bands, and then combines it internally to produce a true colour image.
This camera pretty much did the same thing.

If you have a single picture with multiple objects of vastly different distances all in focus, like the earth and the stars, that picture is a composition of multiple images.

The iPhone uses computational photography, it actually takes multiple images and outputs a single composite image. It may use 2 or more cameras taking multiple shots, or just a single camera taking multiple shots.
