Some of your most beautiful work yet, without a doubt.

Yes...truly dramatic images with genuine impact (unintentional pun!) Wow.

Departing Tempel 1 - animated GIF (4 MB) of 12 HRI clear frames taken starting 50 min after impact, 22 000 km distance and ending over 6 hours later and 10x the distance. Shows the impact outburst subsiding over time. Sun is I believe to the left.

Back to the archives!
Tempel 1 from DI Impactor's ITS camera. Edit: "New" image with changed text ((NASA/JPL) -> (NASA/JPL/UMD)) and lower compression.

With the blurry view off of the focal center of each photo, one gets the visual impression of very shallow depth of field...and without the contexting photos, it's impossible to judge the scale of the alien landscape. You'd be hard-pressed to say that you weren't looking at a close-up of something you were holding in your hand!

"With the blurry view off of the focal center of each photo"
It's not "off the focal". I really missed out some more detailed description. It's actually combination of ~50 images taken by Impactor camera, when Impactor approach Tempel 1. So, every original image has different resolution and different coverage area. Orig. images are combined in some kind of manual superresolution, which provides better results in the central parts of the images, for which more original images exists. Also as Impactor approach comet, image size was changing from 1024×1024 -> 512×512 -> 256×256 -> 128×128 -> 64×64. -------------------- |

At first I got the same impression that Ilbasso did, but closer inspection reveals that it is a combination of separate images that just happen to be assembled with the higher res shots in the center to give a macro depth of field impression. If you were to take a potato and photograph it at a 45 degree angle with a wide open aperture, focusing on the center of the potato, this composite is very much what it would look like. If you've ever used a lens-reversing ring to do macro work, this is what everything looks like. Alas, all my examples are on silver and celluloid so I have nothing to share, but this is a good example of what Ilbasso was thinking of.
-------------------- If Occam had heard my theory, things would be very different now.

Yeah, I noticed the same thing IB did as well...very interesting little effect. Thanks for the technical demystification, Dan!
Oh, and of course really outstanding work on the images, Machi, as per your usual!
