Valles Marineris Mars composite image assembled from Mars Express "webcam" images taken on July 1, 2009.
This image shows the E section of Valles Marineris and the outflow basin of Eos Chaos. The Valles Marineris is a deep set of complex graben that stretches over 2000 km across.
The image is an "HDR Super-resolution HiPassLRGB composite". To make the image, a zip file of the July 1, 2008 was downloaded from the MEX-VMC home page (http://webservices.esa.int/blog/blog/6). The raw images were then converted to rgb.png files using Gordan Ugarkovic's VMC2RGB utility. These images were loaded into Photoshop CS3, enlarged 10x, and an unsharp mask was applied to each image. Next, the aligned images were grouped according to acquisition time to minimize spacecraft perspective differences. The set was then reduced 50%. Level adjustments and Masks were created to allow only the midrange exposed images to overlay with the base images (Image No. 1 and Image No. 6).
To make the RGB Color layer, a Hue/Saturation level was added (+40) and a Channel Mix layer was added (R: +170%Red, -50%Green, -20%Blue; G: -20%Red, +140%Green, -20%Blue; B: -50%Red, -20%Green, +170% Blue). The color image was Gaussian Blurred 5 pixels.
To make the luminance (L) layer, the unblurred color layer was converted using a B&W conversion layer with R:+60%,Y:+70%,G:+70%, C:+20%, B: +50%, M: +50%). The luminance layer was combined in the stack with the Luminance blending mode. Above this was placed another B&W converted layer, this time with a 30 pixel HiPass filter that was blended with the other layers in the stack. A Hue/Saturation layer and a final level adjustment were added to make the final composite.
Image scale is approximately 2 km per pixel in the original size image.
North is approximately at the top of the image.
