Rybags Posted November 11, 2015 Share Posted November 11, 2015 The pic from Mario is a good effort but loses a lot of it's underworld doom/gloom feel with the luma adjustment. But it's the weakness of Atari's colour generation here at fault. The higher end of the available lumas have nice small increments where the lower ones have large steps which makes representing anything dark very hard. Of course though, the Atari's suffering is insignificant compared to any other computer of the time except those few with better palettes such as IIgs and Amiga.

Synthpopalooza Posted November 12, 2015 Share Posted November 12, 2015 That underworld picture is very hard to do ... I am going to try to do this picture in my Super 9 DLI mode ... Graphics 9 with about 256 unique colors per 8 scan lines and 136 possible unique color palettes usable. The resolution will be low, but I think I can nail the colors down accurately. It'll be posted in my own Super IRG pix thread so as not to derail things here any. 1 Quote Link to comment Share on other sites More sharing options...

MARIO130XE Posted November 16, 2015 Share Posted November 16, 2015 Thank you for this but I didn't know conversions took this long. There's a lot of higher priority activities in my life than converting requested pics. Especially on weekends or non working days. Anyway... here are the 1st two pics. My personal opinion: I would prefer my PAL-Machine. The colors looks wrong in my altirra with NTSC-configuration but maybe on real hardware the colors are okay.

I was amused because you posted that one conversion was running four days earlier than my post. I can't even run conversions with large numbers of iterations on this old single core box. They bring the machine to a crawl. I've been puzzled by the PAL versions of your executables. They seem to look acceptable in both Altirra and Atari800 each in [EDIT] NTSC mode. However, on my real NTSC 800XL the colors are badly shifted.. I'm looking forward to trying these two NTSC conversions. Thanks, and again I'm sorry for any misunderstanding. -SteveS Edited November 16, 2015 by a8isa1 Quote Link to comment Share on other sites More sharing options...
José Pereira Posted November 16, 2015 Share Posted November 16, 2015 The snow house looks great but not the river one. I never did anything using Rasta Converter because my usual stuff goes well with G2F and I'm addicted to think 'How to' and do things myself so I don't know why. Maybe one day I'll get some time to study and try it a little bit but no, now it would be a waste of time for me. But respect and I usually like all pictures that people post, some are trully amazing. Quote Link to comment Share on other sites More sharing options...

Synthpopalooza Posted November 16, 2015 Share Posted November 16, 2015 (edited) I am going to try this one ... a MIN and a Super 9 render shall appear on my Super IRG thread by tonight, with luck. This sort of picture is ideally suited to MIN (12 + 9) because of the low number of chroma in the picture. We will see.

But respect and I usually like all pictures that people post, some are trully amazing. I find it helpful to compare converted pictures with originals. I didn't see links to them so I tried Google image search. Below are the returned pictures. I think they are the correct pictures. Snow river in Sweden Snowman BTW, I'm amazed that Google image search was able find the images using screen dumps from an emulator, Atari800, of converted pictures with reduced colors and added dither(s) Edited November 16, 2015 by a8isa1 Quote Link to comment Share on other sites More sharing options...

+Philsan Posted November 17, 2015 Author Share Posted November 17, 2015 Colors are not OK, but here is a straight conversion without dithering (51 unique colors): If someone wants to make other tests, you can use that version of Miker's image; I scaled it and removed upper ugly lines. 1 Quote Link to comment Share on other sites More sharing options...

gozar Posted November 18, 2015 Share Posted November 18, 2015 Is there a way to run these pictures in a slide show on the Atari? Quote Link to comment Share on other sites More sharing options...
emkay Posted November 18, 2015 Share Posted November 18, 2015 Actually, I didn't try the version 7 before, due to several circumstances...... It really is a step ahead from the older versions. Even more interesting: It works more in the way of my proposals... keeping the details better... So thanks , afterwards.

MARIO130XE Posted November 18, 2015 Share Posted November 18, 2015 my 2nd try of mikers pic. still not really acceptable in altirra. will check it again later on real CRT. output.xex 3 Quote Link to comment Share on other sites More sharing options...
a8isa1 Posted November 18, 2015 Share Posted November 18, 2015 Ho ho hoooo. Bit early but I like the pic. Mario130XE_XMAS.png Wow! This is my favorite converted picture. Not only are the colors great but the picture is still recognizable as something that was drawn (as opposed to sourced from a photograph). Also, the dithering works perfectly with the image. Thanks! 1 Quote Link to comment Share on other sites More sharing options...
