+Stephen Posted June 6, 2013 Share Posted June 6, 2013 On a related theme, I present an accidental run of 1.2 Billion iterations, no dither, altirra palette, 10,000 solutions. This one looks incredible on the real hardware. breakout.xex 1 Quote Link to comment Share on other sites More sharing options...

Philsan would you please redo the 800 one using OlivierN palette (see attachment) so that I might enjoy it on my NTSC machines? palettes.zip Quote Link to comment Share on other sites More sharing options...

Rybags Posted June 7, 2013 Share Posted June 7, 2013 (edited) Wow factor on the boxes, especially showing so many shades in one line for the 130XE. I think the next step in this whole thing might be a movie builder, although of course the pre-processing on PC side might take days for a few seconds worth of footage and playback would involve an IDE class device.

iratasan Posted June 7, 2013 Share Posted June 7, 2013 The above Atari 800 box (PAL model) is mine! I recently got it from the UK. I am currently looking for the so called Atari 800 "international" Owner's Guide (containing text in 5 different languages). Does anyone own one or has at least seen one? Here is the same for the A400: http://www.atarimania.com/documents/atari-400-computer-owners-guide.pdf Let me know! Quote Link to comment Share on other sites More sharing options...

The photo given to me by iratasan doesn't need no more photoshopping for that. You only have to be patient because the conversion needs a lot of time. 1 Quote Link to comment Share on other sites More sharing options...

Conversions seem to tie up what little resources this machine has. Quote Link to comment Share on other sites More sharing options...

a8isa1 Posted June 9, 2013 Share Posted June 9, 2013 (edited) Thanks again, Philsan! What I see in the .PNG is exactly what I see on my monitor and my TV using my 800XL. The colors matchup exactly. One thing that is strange though. The top of the 800 has that orange color. It seems brighter and, well, more colorful than it should be. That color matches the .PNG but it seems out of place Could the palette be off for just one color? This question is for anyone who can offer any insight. -Steve Edited June 9, 2013 by a8isa1 1 Quote Link to comment Share on other sites More sharing options...
ilmenit Posted June 9, 2013 Share Posted June 9, 2013 That color matches the .PNG but it seems out of place That is the problem with limited color palette on Atari and dithering. You have to diffuse error into other pixels and when pixels are big, they don't blend well if closest colors of Atari palette are too far from original ones. The yellow top of the picture is caused however by default /predistance=ciede. CIEDE2000 gives more saturated colors when they are close to gray. This is what you expected usually, but it doesn't work for things that should be grey. For that case other /predistance options are added.

Why didn't Philsan's original rendering of the same picture exhibit a similar result? Quote Link to comment Share on other sites More sharing options...

Why didn't Philsan's original rendering of the same picture exhibit a similar result? The difference is in palettes. In OlivierN palette some of those grey colors were closer to yellow than in PAL palette. Finding the closest color to some other from limited set (Atari palette) is not that easy as it seems: http://en.wikipedia.org/wiki/Color_difference Edited June 10, 2013 by ilmenit Quote Link to comment Share on other sites More sharing options...

A Fili'.... ringrazia che cio' na fotocamera Panasonic dell'anteguerra (1600x1200)... un minimo di lens-distortion e' fisiologico da vicino... Se uso lo zoom (solo digitale) e' peggio te l'assicuro... E poi per produrre un'immagine di pochi pixel e pochi colori va piu' che bene dai! La ritagli un minimo intorno e amen! :-) Su su!
