Not natural at all, I was going for abstract  I just liked the effect... just trying something different, imagining what the view would be like if the dunefields "caught the Sun" briefly and reflected it back...

QUOTE (babakm @ Dec 13 2006, 04:22 AM) If JamesCanvin's image is at full resolution (~25cm/pixel), the ~100 pixel length of the shadow + ~41 degree angle of the sun -> height of ~22 meters. Not as impressive as I initially thought, but still as tall as a nine-story building. No it's not. Here is the full res version - double the size so it's ~44m tall.
Oh and on refinding the mount I realized that my pixel coordinates in the filenames, taken from the 'center' values in Expressview are screen pixels and are therefore wrong if not zoomed in all the way. So some of the coordinates given so far will be wrong. James -------------------- |

This one's for ustrax... again, not trying to be 100% colour accurate, but going for something a little more abstract and, well, attractive for the sake of it.

I know this request will be blasphemy for some, but...
I for one would appreciate a 10 or 25 meter scale bar somewhere on each HiRise image. The “human scale” of planetscapes and moonscapes is what has always attracted me to unmanned space flight; I love to imagine myself at the scene. Could I step over those polygonal cracks at Becquerel? Standing in a trough in the dust lake, could I see over the next dune crest? Problem is, I have to carefully read the caption or get out the calculator to figure out the scale – how much more user-friendly to have a scale bar in each image. Instant gratification! |

I can imagine it...Earth's sky taken by their robotic landers being tweaked to caramel since blue is just...well too alien for some back on Mars. Andy |

I like this one, Stu (which frame is it from?) your colorizations are getting better and better ... nicely balanced "true-colorish" hue palette, yet not too monochromatic/casted ... just the overall brightness could be improved (it's a bit too dark)

Thanks Nirgal, I really appreciate the constructive comments and support. I finally feel like I'm getting somewhere now... I hear what you're saying about that image being a bit dark, maybe that's a glimpse into my character...!

Stu, I like dark for a medatative image. Think Mark Rothko!
