Shay did an appropriate thing to allow others to view your image. This
obviously is in your interest if you are at all interested in sharing your
image with others - and you would not post it here is you were not
interested in sharing it.
Please note that you broke etiquette of these groups by posting in a not
widely supported format for no benefit whatsoever. Your claim about
introducing artifacts that deface your image is ridiculous. You are free to
put your images on a website in any format you wish, but *please* try to
avoid posting in formats most people in these groups cannot view without
hassle.

Whoopie.
You know very well as to what I was referring to. Have enough courtesy
to not to do it again.

Two words: gradient banding - and people can see it. Since POV is
capable of 16-bit colour depth I chose to utilise it and keep that
depth for the on-line version too.
However, how a particular piece of software or hardware device
displays a 16-bit image is another matter which is pretty much out of
my hands. Even with a 16-bit image, some platforms may introduce
banding as they attempt to display the image in a reduced depth.
Still, at least with a 16-bit colour depth image, the gradient-banding
reduction intent is there.

Perhaps not, but the reposted image looked horrible compared to the
way I prepared it. I do not think it was a good idea to repost the
image in a manner that detracted from the original.

Different strokes yadda yadda. If you can see it, fine - if you
cannot, fine. I have merely presented the image in the manner in which
I intended it to be.

This is true, but at least I hope I'm making an effort to use new

Without my permission and in a manner that detracted from the
original.

It was shared in the format I intended it to be shared in. If people
cannot see it, fine. Those who can, fine. I am merely attempting to
move on in image format technologies. We cannot merely sit still.

Yawn. Here we go. Show me exactly where it says I cannot do this and I
will not. Otherwise, you are merely projecting you own desires as to
how one should "behave".
>introducing artifacts that deface your image is ridiculous. You are free to
If that is ridiculous, then see the attachment. I think you will find
it is your statement that is ridiculous. Hopefully, you are not so far
back in the stone-age that you cannot view a PNG formatted image.
>put your images on a website in any format you wish, but *please* try to

If you cannot keep up with image format developments, I suggest you
remain quiet on the subject.

right on! The original poster should post normal
standard jpeg, or not post at all.

I'm not adding to this argument any, but I do have a question. Am I correct
in assuming that my SVGA trinitron monitor cannot display the increased
color depth of IMBJR's original? Different hardware is required, no? I can
see the improvement in the quality in IMBJR's png posting but I can still
only see 8 bits per color channel, no?

That's what you can do on a personal website. But when you post on a
privately owned news server you are expected to follow the guidelines
set by the owner.

Well, right there in Thorsten's post if nowhere else.

Thorsten is a member of the POV-Team and thus have full authority to act
on behalf of the owner of this news server. He have just wrote to you
that you "cannot do this" and so you need to look no further where it is
written. Convenient, isn't it?

Fine. If you all want to sit still. So be it. Substandard JPEG it is.
By the way, is it my imagination or is there more format leeway on the
animation gorup - or is that because there's less formats for
animation?

This is something I touched on in another post. The problem is out of
my hands in terms of how hardware/software renders such images. They
will either do a bad job and potentially introduce gradient banding or
they will attempt to mimimise the effect and use dithering.
I'm certainly no expert when it comes to hardware - for all I know,
VDUs have been able to support such colour depth for years.
