Allowing JPGs for Screenshots
I do like much the "Screenshots" from a Bigscreen (beamer at a Party), but I cant upload such, because jpgs are not allowed, png is too big, and 256-col gif looks ugly.
I think allowing jpgs would be fine, because that would show a little bit of a party atmosphere into csdb..

isn't the 'patent' (iirc, it's not valid in the netherlands anyway) going to run out in a couple of months (or didn't it already?)? Then i say Gif or Ping. |

OK, I have a mobile-phone-picture with light reflexes, blurring and all.
Converted to png, it takes ca. 80KB, which is above 30K.
The original jpg is 10KB big.
It might still be argued, that this is not a valid Screenshot, but it looks much better..
If the people here insist on a certain mode for screenshots, i might ask:
Only Emulator Screenshots ?
Emulator with PAL-Emulation Screenshots ?
C64 to Framegrabber Screenshots ?
And why not photographing the Monitor or bigscreen ?

The GIF patent has expired, and can be used freely. Unisys sent out a statement saying the format is free to use shortly before the patent expired, as a sign of good will (utterly lame). PNG is still a better format though, and as long as you don't use transparency you won't have problems with IE bugs.
As for jpg photos - it's *screenshots* we want in the databse not party photos. Emulator snapshots, video grabs of real 64s, or photographed screens - it doesn't matter. A clean screenshot is easily less than 30k when saved as a PNG.

Screenshots from a 1084 are allowed, Screenshots from a beamer not ?
Well, with some luminance-fiddling, I might be able to reproduce the "party picture" with a "real" Screenshot.

HCL: I don't know if this applies to every system, but a scaled down 256 or 16 color GIF looks... er... "choppy", I guess, on my computer, whereas a full color PNG scales a bit more smoothly. It's difficult to explain, and I may be the exception rather than the rule (damn Mac), but it's something I noticed.
Back to Topic: I think Magervalp knocked this one on the head... we're looking for CLEAN screenshots, not fuzzy "photograph the screen" pictures. The picture as if it was just dumped digitally off the C64. You don't need more than 16 colors for that, you don't need lossy compression... hell, an uncompressed .BMP could probably display what needs to be displayed in 10k or less. Even if you were to take a proper screenshot, the JPEG compression would hurt it simply by existing. So there really is no need for it.

Of course you can use photos of a projected C64 screen - as long as it's a clean photo, that fits in 30k when PNG compressed.

I agree. A screenshot should have no more than 16 colors. In rare cases where the emulator cannot give a good picture of the demo/pic/etc, use photo (converted to 16 colors!! ;). |

/me seems to be in a very small minority :-(
OK, I'll upload valid Screenshots, and put my bigscreen-photo on a seperate webpage..

Actually, with PAL colour blends you need more than 16, but you knew that :) |
