Ever wonder how #JWST images go from raw telescope data to the beautiful press release images you see on social media?

Check out this video series from @spacetelescope. I was on the team that put these together.

In this first video, we show you what the raw data looks like and how you can download it yourself.

Learn more about the process here: webbtelescope.org/contents/art

The second video about how #JWST images are made goes into the first steps of image processing: downloading the data, stretching it, and removing artifacts introduced by the telescope.

Next, we add color: we shift the infrared light seen by #JWST into visible light, assign colors to different filters, combine them together to make a color image, and then play with the color balance, orientation, and crop to make aesthetically pleasing images.
