How do you think they took this photograph?

If all of this talent was really on one stage at one time together, that is the true miracle of this picture.

Personally I doubt they were all there at one time. After all ... It’s Hollywood ...

Seriously, check out the video. :-)

Cool, I didn't even notice the video. But it was still a Hollywood trick, they just rolled out a red carpet and all the stars ran right to it. They couldn't help themselves.

Here you can see the whole picture. The size is only 4987 x 2000 px. As 2.000 is and odd height, I think it's simply a crop.

For sure it must be taken with a good camera and lens, but many DSLR can make a picture this width, no necessarily a medium format camera.
