Roman Makhin: I took 7 images from the Dec 23rd 2009 (2009-12-23_01.13-01.42) observation: 09-357_01.20.42_VMC_Img_No_11.raw, 09-357_01.23.38_VMC_Img_No_15.raw, 09-357_01.26.34_VMC_Img_No_19.raw, 09-357_01.29.30_VMC_Img_No_23.raw, 09-357_01.32.26_VMC_Img_No_27.raw, 09-357_01.35.22_VMC_Img_No_31.raw and 09-357_01.38.18_VMC_Img_No_35.raw. I extracted the colour information from them using version 3 of the vmc2rgb utility, then processed the images through colour mixer in GIMP and, finally, applied auto white balance. I was using Auto Pano Giga 2.0.6 software (spherical projection, exposure correction) to create the mosaic. Image Credits: ESA/Roman Makhin Image submitted by Heinke le Roux, Lindsay, Ont., Canada. Heinke writes: Public submission by Martin Ahr: I have created an animation from a VMC image series that was made on November 5, 2009. It shows what I believe to be clouds onto which the sun starts shining as the rotation of Mars brings them towards the sunlit side. There are clouds which appear to move also in a direction transverse to the direction of rotation of Mars, and some seem to disappear as the sun starts shining on them. For each frame of the animation, I combined three images from one of the exposure bracketing series into one HDR image. I tried to also use the fourth image having the shortest exposure time. However, the HDR program I used could not combine this image with the other three images, probably because the difference in brightness between the image and the other three images is very large. Since the sunlit side of Mars is overexposed in all three images used, it remains overexposed. However, the dynamic range of the HDR image is sufficient to cover the entire brightness range of the clouds. I then took the logarithm of the brightness values of the pixels in each HDR image to obtain images that can be displayed on a monitor while still showing the full dynamic range of the HDR images. Thereafter, I shifted the images such that Mars it at substantially the same position in each image, combined the images into an animation and rotated the animation such that the sunlight shines from the right. I tried several orientations, and, in my opinion, this one looks most natural. Unfortunately, Mars is moving out of the camera's field of view at the end of the series. Since the clouds are not shown any more in images No. 30 and later, I omitted these images. In the remaining images, I made the cut off portions transparent (which can be seen in the animation at the upper right part of Mars). GIF images can comprise only 256 different colors. Therefore, I converted the images to grayscale. This does not make much difference, since the color saturation in the original images is so low that colors are almost invisible. I used three computer programs for the processing: Fitswork for reading the raw data, extracting color information from Bayer patterns, shifting images and calculating logarithms of brightness values; FDRTools Basic for creating HDR images; and Gimp for combining the images into an animation, minor adjustment of the brightness of individual images and rotating the animation. This is a list of the VMC images used for the animation: Frame 1: 09-309_19.02.06_VMC_Img_No_3.raw,09-309_19.02.59_VMC_Img_No_4.raw,09-309_19.03.53_VMC_Img_No_5.raw; Frame 2: 09-309_19.05.39_VMC_Img_No_7.raw,09-309_19.06.33_VMC_Img_No_8.raw,09-309_19.07.26_VMC_Img_No_9.raw; Frame 3: 09-309_19.09.13_VMC_Img_No_11.raw,09-309_19.10.06_VMC_Img_No_12.raw,09-309_19.10.59_VMC_Img_No_13.raw; Frame 4: 09-309_19.12.46_VMC_Img_No_15.raw,09-309_19.13.39_VMC_Img_No_16.raw,09-309_19.14.33_VMC_Img_No_17.raw; Frame 5: 09-309_19.16.19_VMC_Img_No_19.raw,09-309_19.17.13_VMC_Img_No_20.raw,09-309_19.18.06_VMC_Img_No_21.raw; Frame 6: 09-309_19.19.53_VMC_Img_No_23.raw,09-309_19.20.46_VMC_Img_No_24.raw,09-309_19.21.39_VMC_Img_No_25.raw; Frame 7: 09-309_19.23.26_VMC_Img_No_27.raw,09-309_19.24.19_VMC_Img_No_28.raw,09-309_19.25.13_VMC_Img_No_29.raw.
