Dear all,
We are amazed, and a bit flattered, by the interest that the Dawn mission has awaken throughout the internet and particularly in this forum, and we would like to thank you for it. Space imagery is frequently subject of discussion and even re-work in these pages, but the field of space operations does not seem to be covered very often. That is why we have decided to offer you all the posibility to ask your questions to the team, that we will gladly reply within the limitations provided by our working agreements with JPL/NASA and the Dawn Science Team. We would like to request in advance your understanding if we do not reply promptly (or not at all) to some of your questions. We are in a busy and exciting time, and we intend to share this excitement with you as much as we can. Thank you all for making a great site out of UMSF and for your participation in this topic. Regards, Pablo Gutiérrez-Marqués Framing Camera Operations Manager -------------------- |

Welcome, Pablo, we're absolutely delighted to have you here.
It's clear that the images of Vesta that you have posted so far have been enlarged, and I am sure they have been processed in other ways. Can you tell us a bit about how you are processing your images before sharing them with the public? -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

It's clear that the images of Vesta that you have posted so far have been enlarged, and I am sure they have been processed in other ways. Can you tell us a bit about how you are processing your images before sharing them with the public? It is a well-known fact in this forum that heavily-pixelated images do not do great magazine covers. So in order to save the public the effort of squinting and turning the images around, we at MPS ( http://dawn.mpg.mpg.de ) applied an oversampling filter (like Lanczos) that removed most of the pixelation and provided more roundish features, like the ones might expect at Vesta. Concerning the brightness, we have simply tried different stretching functions until we found one that showed the features that we intended to show. However, the images released so far are not only the workings of the Framing Camera Team but also of the greater Dawn Team and some of them might have undergone a slightly different process. -------------------- |
