I'm curious; is anyone else going to provide a copyright image (see 4.g on
http://www.povcomp.com/rules/ )? I'm considering making one so that I can
ensure it will look good with the image, but I'm not sure what to make it
say, other than the obvious "copyright 2005 me". Is there anything else that
I might want to include? What sort of information do people usually put on
their images?

  Your CV would be good.

"All rights reserved" seems to be a good one. I 'think' it's internationally 
known and recognised, but don't quote me on that. ;)

Thanks. I think I'll include the simple copyright message and a link to my
website.

Another question: since I'm supplying a PNG copyright to be overlaid on top
of my image, I assume someone will be recompressing it. Because of this,
should I favor high quality compression over low file size in my submission?
Normally I'd sacrifice a little quality to bring the file size down, but
would it be wise of me to avoid doing that?

And out of curiosity, are lower-resolution, higher-compression versions of
each image going to be made available for the benefit of those with small
monitors or slow internet connections?

I would imagine it would be best to provide the highest image quality
possible within the 5 MB file size restriction.  That's what I'd do anyway
:)

At a guess, I think once the juding process is finished and the images are
made publicly available, they will be available at one or two different
sizes.  I suppose whether they recompress them, provide alternative links to
the original full file size versions, etc, will depend on what the images
are like (e.g. whether someone submits an absolutely huge image).  It says
in the rules "The organisers may, at their option, resize and/or recompress
your image if need be. This includes but is not limited to making thumbnail
or preview images of it.", so it seems likely that there will be some
recompression/rescaling happening at some point, so there could be multiple
versions of differing sizes for the purposes of browsing the submissions
easily.

These are, of course, just my personal opinions :)

	Why?  PNG uses a lossless compression scheme, so if you tell your
graphics application to use the maximum compression (this is typically a
value of 9 for PNG) then you'll get the smallest* filesize for the exact
same quality.  Simply it's slightly longer for the app to write the file
(and also to read it again), but on nowadays computers it's lighting
fast, especially compared to a POV-Ray rendering  :-)
	POV-Ray has no such setting, as it always compresses PNG with the
maximum possible compression with respect to how it renders its images
i.e. line by line**.

(*) in fact not always, other softwares are sometimes able to recompress
slightly more some PNG images that were saved with the maximum compression.
For instance: http://pmt.sourceforge.net/pngcrush/

(**) therefore the (*) above might be worth the try with an image created
by POV-Ray, as such extra tools will compress the file based on the whole
image data instead.

Let me clarify; there are two images I'm talking about: the POV-Ray image
(jpeg) and the PNG signature. I was asking about the compression of my jpeg
image, since later on I know the PNG image will be overlaid on top of it and
then it will be resaved as another jpeg.

	Okay, got it  :-)

	Since the rule 4.d. says you have to submit your main image in JPEG,
I'd suggest in all cases* to submit your JPEG images with the best possible
quality (lowest compression).
	Under e.g. Photoshop, it seems reasonnable to choose a quality level
between 80% and 100% for this purpose.  80% should suffice in most cases;
at 100% images are still lossy compressed but can be much bigger, depending
on image complexity, for visually the same result.

* unless you have a very slow dialin connection.

Modify this file to suit your needs:

<code>
#version unofficial MegaPov 1.1;
#include "screen.inc"

#macro scrCopy(_src, _trg, _col,_yr)
   Set_Camera(_src, _trg, 90)

   // Copyright notice
   #declare cdir = vnormalize(_trg-_src);
   #declare crgt = vnormalize(vcross(y,cdir));
   #declare cup = vnormalize(vcross(cdir,crgt));
   #declare cpt = vnormalize(cdir*10-cup*4.5);

	#local _msg = concat("(C) ",str(_yr,1,0)," by David Wallace");
	#local _msob = text {
		ttf "chancery.ttf" _msg 0.01,0
		h_align_right
		pigment { rgb _col }
		scale .02
	}
	Screen_Object (_msob, <1.0,0.0>, 0.01, true, 1)
#end
</code>
