I think the best way to determine the sizes and colors of the logos is to know where and how they are going to be used.

Is the logo going to be used to start POV as an application ?
-> a 16 x 16 and a 32 x 32 colored icon is best suited. This one should display only the symbol. There is no space for lettering.
The 16 x 16 is needed in windows to start the applications.
The 32 x 32 is the average size for icons on desktop ( Linux and windows). I think Mac and Amiga users have about the same needs.
 

Is the logo be displayed on the POV-Ray Homepage ?
-> any full-color logo with about 128 x 128 pixels should do. But in this case, it should be up to the 'logo designer' to decide how large the original size should be and if the logo should be square or not. Any large image can be downsized to about 128 x 128 and still be easily recognizable.
 

Is the logo meant to be used for Web pages ( ie : comparing render stats or pictures between POV and BMRT, or links to tutorials or the POV Homepage) ?
-> a size between 32 and 64 pixels should do. There again, a webmaster can easily downsize a 64 x 64 logo to 32 x 32. That's why I would stick to a 64 x 64 logo ( upsizing a 32 logo to 64 would ruin it).
 

Is the logo to be inserted in one corner of pictures as a 'made with POV' scheme?
-> a black and white version of the 32 x 32 icon with the symbol should be fine. A 32 x 32 logo may look large on some pictures but it can be downsized. And there again, it's up to the designer to decide if it should be square or not.
 

To sum up, I think the following formats for the 'contest' should be :

1° -  a 32 x 32 pixels colored logo with only the symbol ( to be downsized to 16 to suit needs) [Application starter].
2° -  a large size image of the logo ( above  320 x ? ) with full details, colors and lettering,...and whatever you can think of for banners and the homepage is POVadmin agrees. This is one to be downsized to about 128 pixels [Banner and Homepage]
3° -  a 64 x ? colored version with symbol and/or lettering. [Web-Page]
4° -  a 32 x ? black & white version ['Made with POV' logo]
 

Tell me what you think, but my opinion is that we should know beforehand how the logo is going to be used to know where we are going.

Rune a écrit :

After having found out the general qualities of the logos we can proceed and
begin to discuss the technical requirements. That is mainly about
resolutions.

I suggest that each logo should on the voting page be presented in the
following 5 formats:

A 32x32 pixel black and white version. Shades of gray is allowed, but only
for anti-aliasing. For the reason of keeping the sizes small I think 16
shades of gray is enough. I personally hardly can tell the difference
between 256 shades of gray and 16 shades of gray, when the shades of gray is
used only for anti-aliasing.

A 14400 pixel black and white version. This version must contain 14400
pixels at most, but the logo-designers can decide for themselves if they
want a 60x240, or 80x180, or 120x120 resolution, or something completely
else. This is so no shapes of logos are favored. Shades of gray is allowed
in the same way as in the previous version.

3 custom versions. For these 3 versions the size limit is 14400 pixels as in
the previous version, but any amount of colors may be used. These versions
are supposed to show how interesting the logo can be presented, and how
flexible it is. It is encouraged that the 3 versions are made as different
as possible, to show flexibility.

So, these 5 formats are my suggestion. What do you think of it?

BTW, the POV-Ray Logo Contest Page is updated:
