Alien Critters On Mars? Check This Out!!!, page 3

At first glance I thought to myself "Well assuming these are objects other than rock, why are they not a different color?" Sure there may be some dust or dirt on them, but you would see SOME variation in color.

Well okay, the one that is the clearest and sharpest detail from Mike's collection does indeed show a drastic difference in color... and the detail in the "critter" is quite fantastic.

Mars color pics are NOT real color ... they are always (if someone can prove me otherwise, please do) color-corrected or enhanced in some manner to bring out features.

No not quite true... NASA on the Rover site where they have over 80,000 images from each Rover and from several different cameras does indeed show true color images. They are DARK... Why? because the sun is further away... And yes the sky IS blue on Mars.... {see next image} On the pad of the rovers is a color chart. What NASA does is to take the color chart and match it to the one on Earth and then adjust the image to WHAT IT WOULD LIKE LIKE IF YOU HAD EARTH LEVEL SUNLIGHT...

They also create red/green images that are meant for 3D viewing. And they also create UV/VIS images to enhance features for comparing minerals etc..

Here is a Sunset on Mars in true color... dusty sky but it is a BLUE sky...Posted it in the other Mars thread so many of you have seen this..

Now I would assume this is not a batch-typeob, as some images would require a different "filter" per se to bring out that image's particular features. But even assuming that raw data is spit into a computer which applies one standard filter to all images ... you are not seeing raw data. We can assume that anything CAN BE edited in/out of the image IF the image is indeed corrected in any way before we see it. Like the color pics. This leads me to believe that someone has the power to make sure any anomalies would be removed if they did indeed exist.

Assuming is BAD

especially when info is available... The Rovers have built in software that automatically edits anomalies based on programmed values, but they don't catch everything... How do NASA scientists then see what they want that we can't? Simple Algorithms... look it up... there are scientists that have created some really interesting and top secret ones. Basically they are encoded in images and without the Algorithm you cannot decode them...

So best we can do is look for the ones they missed...

Now it is my understanding that the b&w pics also have some contrast filters applied to them. Can anyone elaborate on that?

Adding contrast does not generally change the object unless you over drive it. Contrast, brightness and gamma correction merely make an image clearer to see. I am sure there will be some who argue that... Oh well...

That all being said, I'm 100% sure that even if any of these pictures DID really show anything other than rocks, we'd really have NO WAY WHATSOEVER to verify it one way or another. Unless Mr. Lear has any input ...

LOL Well you can sign up for Astronaut training Lots of openings right now... new Moon and Mars missions in the works... or send your kids... I can wait a couple years to see what they say

Maybe I will ask Buzz what he saw, but I am sure he won't give me much. Him and John Glenn are in town tomorrow to open a bridge...
