Lunar Orbiter's originals vs. LOIRP restorations

Keith Cowing (LOIRP)

Keith's note: These images are taken from Lunar Orbiter II image LOII_092H1 Framelet 522. On the left is the highest resolution scanned version available online at LPI (or USGS). On the right is our partially processed version that we retrieved this morning.

In addition to providing a much sharper image, note that our new image also allows contrast to be controlled such that features can seen in the areas that are darkened in the older image. Right now we are focusing on retrieving Lunar Orbiter II images at the request of both LPI and USGS since high resolution (modern) scans have yet to be done for this mission's images.

We hope to have the entire image online later today complete with collapsed lava tubes (?) and giant boulders sitting in the middle of otherwise flat plains. With our recently enhanced (restored) original FR-900 tape drive and its recently restored sister drive we will soon have two fully functional drives in operation and will be able to (eventually) retrieve and release images on a daily basis.

I will be doing a live webcast tomorrow at 1pm PST wherein we give you a tour of our facility and watch as we pull a new image back from history and into the present. Details to follow.
