Hi, I've tried without luck to track down the source data for this image Hubble/ESA Earth poster. It's fairly artificial looking, but a few people told me/speculated it was not CGI. It's so high rez I'm guessing Blue Marble series with lots of color work but unsure.

thanks,
stephen

Update - I've been working with Gordan's LRO Earth shot which appears to be the best of images available. I was able to use some Photoshop work to increase the usable resolution without artifacts. The scaling in Photoshop CC is much improved and outperforms my specialty software. Still not high enough for all the shots and I will have to work with some Apollo & Rosetta shots for matching limb shadows.

Gordan - is there any LRO imagery with Earth not full disk?

Doug (or anyone) - I've looked all over for Rosetta OSIRIS mosaic data but I've not found anything where it imaged a disk mosaic. Have you?

I haven't been paying close attention, but I expect if there were it would have been announced/released publicly. I'm only aware of two low phase shots, one has part of the Earth clipped off and the other one is the one I colorized.

As far as I know, there are no disc mosaics of Earth. The highest resolution stuff is of the crescent Earth where it fills up most of the 2K by 2K detector, but most of that disc is in darkness so...

Thanks a ton for the info. I will do the best I can with Apollo photographs. If I can find phase and geography match, I will just use the darkness as, well it's dark. The trick will be transition, but I developed some exposure techniques with matching disparate Cassini mosaics using linear light in 32-bit floating point which make things behave according to laws of optics in nature. Hopefully that will work well enough. If not, then I will be limited to full disk Moon shots
