Selfless,

I can’t do anything about your mistrust of NASA or the Cassini photo’s. I might be able to help you understand the images a little better. I am a working CGI professional with 19 years of experience. My wife is and award winning photographer and I have 20 years experience as an amateur. I’m more advanced than many professionals’ are. We use both film and digital equipment all Nikon Professional bodies and lenses. I can not blame you for your mistrust of photos on the web. There is a lot of abuse and outright fraud especially where UFO photos are concerned. It has made me very skeptical myself.

On your monitor you are viewing these images at 72 dpi (dots per inch). Your eye fills in the area in between so you are unaware you are viewing a series of dot’s. The same goes for images printed from your computer. I print at 300 dpi or above. When I need the extra detail I routinely print at 1200 dpi. When you make a print from film it is continuous coverage (not dots). Because of this the digital image appears too perfect and too real at times. A lot of the tiny detail is missing and even though you can not see that it is missing visibly your eye picks up on that and there is something not quite right about the image. Especially high quality uncompressed images. Most images you see on the Internet are highly compressed and have many artifacts making them look a lot less than perfect. When you see a high quality compressed image or a raw uncompressed image it looks to good to you because you are used to seeing the garbage usually shown on the Internet of necessity to keep the file size small. Internet images are also generally sharpened through various methods to compensate for the lower quality of a digital image when compared to a film image. A negative contains more information than a digital scanner is capable of picking up. I have read it would take a scan of near 38,000 dpi to equal film quality. A 38,000 dpi (optical not through interpolation) scan of a 35mm negative would be such a huge file, your computer could not even open it. I scan at 4,800 dpi (optical) to produce print images at up to 11inches x 14 inches, which works out about right. So you see the 72dpi images you are viewing will never look as real as a print from a negative.

I’ve spent the last couple of hours at the Cassini site looking at both raw and full quality .tif images. There are many close-ups of Saturn’s surface and rings. I also did a search and looked at some photos from telescopes. Of course the telescope photos will never compare to the high quality digital images from Cassini. I see no reason whatsoever to believe the images are not real. They are much clearer than the telescope photos but that is to be expected. The telescope photos are shot through the atmosphere and from a much greater distance.

The Cassini images show no sign of any manipulation whatsoever. There is no sharpening and they have not been altered in my opinion. Because they are digital and not sharpened, or corrected they will look to smooth to you. You are just viewing a digital image taken by a good camera that has been unaltered. You are used to seeing garbage photos taken by consumer level cameras. Don’t let the megapixel numbers on these consumer cameras confuse you. A 5.1 megapixel image from a professional camera is so far superior to a 8 megapixel image from a consumer camera that there is no comparison. I currently shoot at about 12 megapixel and there are large format digital studio cameras now that can shoot at 3 times that.

My Conclusion: These Cassini images are authentic. The raw images show no sign of manipulation. These are the best photos you will find until there is a future mission with even better equipment. No image from a telescope will ever equal these images. Skepticism is a good thing until it crosses the line into unfounded paranoia. If you are convinced that all Saturn photos are fake and that every Astronomer on Earth is in the conspiracy then nobody will be able to show you a photo you think is real. Do you need the points for some reason or are you really this paranoid? Maybe you should take a break from conspiracy boards for a while. I don't mean this as an insult or a dig. If you immerse yourself in these boards too much it is not healthy.

Here are two links to close-ups. The first is a raw file and my favorite of the ones I viewed.

Got to agree, you wont get far without backing up your clams that some pictures of Saturn are fake. So why do you think there fake/edited?

You said:



maybe they are edited pictures of the real thing so it looks more crisp.

Thats just silly, your basicaly suggestion then that recent pictures of Earth must be fake because they look sharper than older pictures. Its called technological advancements as cameras get better so does the quality.

Again on a nice still night you can get a very sharp picture of Saturn.

As for closeups of Saturn please don't make me repeat myself I have already explained why there arnt any but i'll give you an example that anyone should be able to do.

Go to your local airport and take a picture of a large plane now you have a problem because to get it all in you have to sacrifice distance therefor you wont get as much detail out of it. Now go right up to the plane and take 50 photographs of it in sections once your done piecing them together you will have your very large but detailed image of the plane, but wait.. what detail? there isnt much to see on a plane anyway. As I explained in my previous post NASA have no need and don't want to waste there time taking a few thousand photos of gas thats all the same theres much more interesting things to explore right now.

If you like you can always have the ESA start a mission to photograph the entire planed in detail I don't think it will cost you more then a few hundred million maybe and 5-8 years of your life.

Please keep in mind that i am not dismissing the photo's because they don't have ufo's in them, i am not being paranoid i just want to see a real photo of saturn up close that has not been edited to look more crisp or a computer simulation of the real thing.

The quality of the pic it self is not the reason i think it's not the original pic.
it's mostly because in all the official pics i'v seen they are different in colors and in constancy with the others. they don't look real because if you look at another gas giant or another planet or another moon for that matter that was taken by a launched probe, those pictures looks way more real then a close up of the entire planet saturn.

It's just my personal opinion that the close up pics of saturn are not the original source of the picture but i am not forcing anyone to agree with me on this i just hope that people would stop insulting others just because they don't agree with them.

Got to keep an open mind.

Just because a person is perceiving something differently than you does not indicate intelligence either. Calling someone stupid without having enough forethought to figure they are on a different track than you does indicate stupidity though.

selfless is stating that there may be more to this than meets the eye. I am not agreeing with this hypothesis, but how do you rule it out? Have you been close enough to Saturn to state that selfless is Wong? You have seen a blurry image through a telescope, but have not seen the real deal.

I think selfless came here, because he/she felt that there might be some astrologists out there that have some pictures that are clear to make an independent decision. Have some empathy and some heart, if everyone was just alike it would be a pretty boring world wouldn’t it?

Looks like I am the only person here that has the guts to defend someone that is trying to think independently!


thats crap...he came here looking for pictures of saturn thats exactly what everyone gave him, but he refuses to believe and also to give answers as to y he thinks they are fake...thats really nice of you to come to his rescue but im sure he needs no babysitter



Hello again friend,


here is the explaination that you missed as to why i think they are not real.


The quality of the pic it self is not the reason i think it's not the original pic.
it's mostly because in all the official pics i'v seen they are different in colors and in constancy with the others. they don't look real because if you look at another gas giant or another planet or another moon for that matter that was taken by a launched probe, those pictures looks way more real then a close up of the entire planet saturn.
