Impressive quality of the raw images from MSL!
When they are Hortonalized, they becomes better!

Promised to get back.

Here are 5 image comparisons, Auto white balanced in Gimp vs. original raw MSSS image from which they were derived. The auto white balanced images all show much greater detail as well as familiar colours to us earthlings. I.e, to get consumer camera type images all one has to do is use a package like Gimp to auto white balance the original raw images and it seems to remove an overlay of red shifting algorithm as well.

Here they are-:

Winston, the Gimp auto white balance really makes the raw color images more sharp but at the same time slightly overexpose color data a bit I think. This can be advantageous at times but also blend over less dominant color information's which could be interesting also.

All in all I would say the auto white balance plays its advantages in the background areas whereas the original raw color is sufficient in the near field (foreground) - just my impressions for now. Smile

By the way there is a curious effect which I intuitively noted from the first images and now also in your images above (best seen in auto white balance): There seems to be an abrupt transition from "clear sky" to hazy/foggy sky at some point in the background. Best seen in your second to last image above - just before the base of the crater wall (where visible)!? Shouldn't this be more of a slow transition normally or do we have to call for Fred regarding the possibility of belt of fogs at the crater walls? Shocked

Here is another example of this abrupt transition:

I have not seen such an abrupt large scale symmetric negative slope before the crater walls anywhere in the HiRISE coverage of the selected landing site which could explain the situation topographically/perspectival.

I'm a little worried about the pebbles on the deck. They could cause mechanical moving parts jammed.

MPJ, I think the "abrupt transition" is associated with the top of a relatively close ridge - less than 500 meters.

I haven't looked at a topological map but it would surprise me if Curiosity wasn't sitting in a shallow depression.

Of course, if MSL had a right Mastcam-100 then we could measure the parallax to the ridge and confirm with our own eyes ( and the attached brain ) the distance.

Nice images in your 242. I too am trying out a few things with image editors to enhance the depth.

MPJ; Re. your #243, I agree that the Gimp auto white balanced images from Curi MSSS raw images might slightly overexpose the colour data.

However, I have not seen any instance yet of the auto white balanced images blending over less dominant colour information.

Those auto white balanced images actually seem to be the digital consumer camera type images that was promised and seem to show essentially what a typical earthling would see of any panoramic scene on Mars but we will have to wait to see how the MAHLI images look with close up images of rocks.

I have a few candidate rocks that I would really like to see some closeups of. They are in the crop below.

Since most of the old posters seem to be following this thread and quite a few new "lurkers" appear to be visiting, gauged by the hits on my Smugmug site, this might be the right place to announce that Kindle US and UK, are publishing my ebook "In search of life on Mars" in mobi ebook format.

It should be available online later today.

There have been a number of changes from the draft which I posted here over a month ago in pdf format.

The epub format should be available from a number of ebookstores in about 1 month's time. The Kindle version has a number of enhanced features as compared with the epub version, such as ability to magnify images on the reader screen and follow links directly.

Looking forward to feedback from the MRB family.

Winston, the blending over is more of a personal perception thingy of mine I guess so nothing to worry about. Wink
The important thing is that Curi cams are delivering very good raw material to work with - even stand off if one can cope with the red layer like I think i can discriminate RGB colors even without white balance in the near field of the raws with some confidence.

I too look forward to the first MAHLI images.
Smile

Horton re 246, it has to be some ridge or something similar as most other possibilities would be kind of fishy. Small scale reliefs are not easy to recognize in the HiRISE images even in the 3d products. Looking forward to some parallax measurements to confirm a topographical cause.

Here is an updated HiRISE view of the landing site (including Curi):

Looks a bit like MSL landed almost in the middle of a small regional plateau which could explain the sharp changes in the background haziness.

And blue sand dunes ahead! I really like the psychedelic HiRISE colors although they doesn't really show off in Gale. Very Happy

Hi LWS,
Sounds very interesting.
Any plans on a version that can be bought from iTunes or apple store?

Yes, thanks for looking, The itunes / apple store version should be available in 2 to 3 weeks time. I don't have an ipad but isn't there a free app on the ipad that allows an ipad user to view kindle ebooks? The kindle version is actually better formatted and has more display features than the ipad one.

LWS,

Yes there is such an app and I have it. But I have never used it because it requires setting up an account. I never did. But I have an account with apple store. This is-probably/might-be a typical arrangement for a significant percentage of your target audience.

Will send the email shortly.

Winston, I am pretty confident that some of the topics you cover in the ebook and which were left open by the MER's (and also Viking that is in the big picture) due to lack of instrumentation and/or interest of the MER scientists can/will be picked up by Curi. Smile

The images in ebook format have greatly enhanced and contribute greatly to the overall understanding now!

I would say it shall be a "must read" in preparation for the MSL journey ahead.

Oops! The release time for the apple store is between 2 to 4 weeks (not 2-3 weeks).

Well. The official MSL Raw image page has been reorganized. Much nicer.

All the Mascam Right images are "disappeared" - but are available here.

Strangely, the first full Right MastCam image of the sundial is OOF ( Out Of Focus ).

I wonder why?

Some poking around:

Some full-size images are in the image directories - but not on the image page!

For example is shown only as a thumbnail but the full-size image is in fact available.

I tried accessing the images and directories using FTP protocol - but the connections never completed.

FTP access must be password protected.

I wonder who - or what - determines when an image in the full-size directory is publically available?
