I still remember when the first Hubble deep field images first came out and blew everyone away. Images of stellar nurseries are really cool too. I'm excited to see what Webb is going to reveal.
The main item to me, is that I really like to know the conditions of the images and especially what type of processing has been applied.
When we get these stunning images, we need to know how the data was processed to get that image.
One of the most common processing techniques is a "color swap" technique. This is where particular EM wavelengths outside of the visible spectrum are "substituted" for wavelengths in the visible spectrum. This then allows us to "see outside of the visible spectrum", so to speak.
These types of images amaze us, and the people uneducated in the field are completely "fooled" by such techniques. I'm not saying that this makes the data bogus, I'm just saying that providing such images and data without providing the conditions and processing will only tell half of the truth.
