On these photos and any othe UFO photos, the process of trying to keep the real is always a problem. The original of this photo is 1408 x 1200 a very nice size indeed. The very moment you enlarge that or do a zoom you create pixels or see a pixelated photo.

A program like Photoshop gives you an option to view pixels at the same size as your monitor so nothing has been changed. Now with out doing any zooms, I snapped a section of the bird. The snap is 317 x 240. Depending on how tou have your Peggy monitor set [at what viewing scale] it should come in that size.

That is why I like film so much better. But one can not ship film back and fourth from mars.


So below is the true photo at the true size in pixels. Pretty small but that is what we work with. For Deuem to work on such a small object I also need to manipulate this size figure and this is where ArMaP and I dis-agree all the time. Who is right and can enlargement from a digital photo represent reality very well or is it a computer driven optical illusion.

This argument can go both ways. I say the computer uses what is there, other say it makes thing up.  In reality it mosy likely does both. But since I look for patterns it does not bother me that much since I can pick up thos same patterns in the pixel sized print, just not as clean because of the size.

What all of us need is a new proven method of enlarging pixels without distortion and keeping them crystal clear. I have not found that yet. So we live in a blurred world or a manipulated one, take your pick.

Try and print out the below but keep it at the pixel size and then look at in with a scope or mag-glass




Remember Pixels are pixels and Dots per inch are just how many of them you print in an inch. So the dpi will not change the pixels just make them more spread out or compressed. Put your face up to a tv or billboard and you can see all the pixels.

Thanks much deuem. I am no expert, but I (and most of us) do have two eyes. :) One of the things I look for in working with the Mars photos is - what does it look like in the basic pic, and then I carefully watch to see if there is dramatic object change as it is magnified. In most cases, I have found that magnification is just fine, until it reaches the point of over mag. Of course, I am talking about using it for "eye-work", not deuem and etc!

Like this bird - from the lowest mag. up, I see no real difference being made in the build and structure of this birdie object. Of course it can be over magnified until it is unrecognizable, but there is no profitable reason to do that.

For the "true-photo" you posted, I see the bird very plainly, just as I have described previously. And it is still looking straight at me, even at its true size!! :)) :))

Good, I posted all of thet so readers can get an idea of what to really look for and what happens in zooms. I will try to print this bird photo out on A4 at a very high DPI count and see what it looks like there.

If this Bird is your find, you have to name it.

How about "M'rs. Birdie"............we will call her "M'rs. Birdie", with the M'rs. allegorically standing for "Mars".

Glad to have you with us M'rs. Birdie, the only "known to be known" real bird on Mars!!! :))

Ok M'rs Birdie it is,

Now can you equate this birdie to any know bird here, maybe find one in the same pose and post them side by side, That would be cooooooool

So we all know exactly what your thinking of.

After looking at two 3D versions it looks (to me) like the "head" is really the rock behind the "bird".

Cross eye version.


Anaglyph version.


Thank you, ArMaP.  That cements without a doubt what I've been seeing since the pic came out.  Two rocks, two shadow sets, and the brains desire to find patterns in chaos.
Time is the fire in which we burn.

Nope, the bird is clearly there, regardless of the skeptical view!  :P

Ok deuem, I have looked at a lot of bird pics, and thus far I do not find what I would call an exact match. The closest I have found is a Bald eagle. The structure of the Bald eagle is similar, with the "broad shoulders" The plumage is about identical with the mixed brownish colors, and for what we see, and the head is white and the beak is yellow. No idea nor feel for size relationship.

I will post a pic that gives us a pretty good comparison view. I am not suggesting that M'rs. Birdie is a Bald Eagle! ;)

IE: not a jpg link. any bit maps or png files.
The problem is that camera stores the photos in its internal memory as JPGs.

Everybody that didn't understood or ignored the reasons were asking for colour photos from the rovers, so now they get them, but as these are three times as big as a greyscale version they use JPG images and we get this.

This following image is PNG image, so it doesn't add any more artefacts to the ones already there. The image can be downloaded from here in IMG format, along with the label (LBL) file. With those two and using NASAview we can see the image, but as NASAview only saves the images as GIF or JPEG I had to use ISIS to convert it into a CUB file, then convert it to a PNG.

Here's the result.

And here is colour adjusted version, just to show how it would look without the (apparently) reddish atmosphere.

PS: if you open the LBL file in a text editor you can see that the image was saved originally as a JPG with 85% quality. Too low. :(

Thanks ArMaP for the work! Still, in every photo the bird is there. There is life of various sorts on Mars, including birds.

Now if you could just tell us the actual size of that bird, that would be good. Or, if maybe we could get a 3D layered print of it, we could have a real model of this bird!! :))

There's a reply to this thread over on rdunks other thread that I posted the other night while being told by My body to sleep.  Many apologies to rdunk.
