I was trying to get a good look at the western wall of Gusev which is pretty low in elevation. I took the images used by Nasa for the Cahokia pan; they show a fair portion of the wall but I wanted to see it better and made this pan for enhancing the wall. I will put a full-res version of this on a website soon.
This is a first version, a 12-bit version is on my mind but the next release is April 22....
Notice that the northwest (lowest part)is not visible. Maybe when Spirit's gets some good transparency higher up the hill this will be visible, in this pan it is hidden by the central ridges in Gusev, also visible on the horizon.

smile.gif Hello grueti. Actually until now I've used Photoshop with the panotools plugin.
I use the remap function and make further adjustments through free transformation>skew or >rotate. I'm sure there are packages like PTGui (I have it installed too among some other panorama software) that make for better stitching but I haven't made much time to experiment with it since I'm used to do it in Photoshop where I have control on the colors of individual frames once it is stitched. For this one (it's 18 frames) I separately adjusted the RGB values for each frame and added a Hue-Saturation-Brightness adjustment channel to make the scene appear more yellow-brown; more or less approximate true color.
The rim however would not appear this prominent in reality, it would appear way less saturated and obscured by dust.
Spend a few hours on it since the files differ greatly. I plan on trying to redo the panorama with more foreground frames included when the 12 bit files are accessible. rolleyes.gif For now (end of this week) I might just redo the first two frames (thet show most difference in hue) and the portion of rim in the eastern direction, it's there but it doesn't stand out like the rest of the rim (intention of this pan) I'm also working on a pan that only includes this portion of the rim. Visibility is better in that pan. For the 'big picture' of the rim Erwan and myself are working on a little something together which should be complete soon.
Thank you for your fine comments.
This is a view from sol 210. Boy I love those mesas..Look at the background and foreground separately, merging might be difficult otherwise.
