MARIO130XE Posted November 18, 2015 Share Posted November 18, 2015 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! OLIVIERN Version is still running. 1 Quote Link to comment Share on other sites More sharing options...
Bryan 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.png I think the key to converting the horse picture is to make the reflection of the moon more like the color of the water. That'll leave more detail available for the horses. 1 Quote Link to comment Share on other sites More sharing options...
a8isa1 Posted November 18, 2015 Share Posted November 18, 2015 (edited) OLIVIERN Version is still running. I look forward to viewing it on my 800XL. Just so you know, the PAL version isn't unpleasant to see. Although, the colors aren't accurate when viewed on my NTSC TV they are in keeping with the winter theme of the picture. No colors shifted to pink or violet or green. Edited November 18, 2015 by a8isa1 1 Quote Link to comment Share on other sites More sharing options...
MARIO130XE Posted November 18, 2015 Share Posted November 18, 2015 (edited) Looks like I can stop the oliviern conversion, because the pal version looks better on ntsc. Are you sure, the oliviern palette is suitable for ntsc conversions? Edited November 18, 2015 by MARIO130XE Quote Link to comment Share on other sites More sharing options...

Synthpopalooza Posted November 19, 2015 Share Posted November 19, 2015 Slight thread hijack here ... an earlier picture, which I did in MIN mode (9+12) ... horses - min.obx It is a real shame that Graphics 9 or 10 could not be somehow incorporated into RastaConverter ... even if it's changing the GTIA setting in the middle of the render. This sort of picture looks ideal, when the Graphics 9 shading comes into play. 1 Quote Link to comment Share on other sites More sharing options...

Are you sure, the oliviern palette is suitable for ntsc conversions? Unbenannt.PNG Please don't think that. Despite what you see in emulators all Rastaconverter pictures generated using any PAL palette have the wrong colors on real NTSC equipment. I wish I could show you what I see but my camera (an old one) shifts colors a little and has bad contrast and brightness with video sources. I'd have to edit screen captures just to present something. My edited pictures would not be proof of what I see. If you have access to Atari800 emulator try this command: atari800 -ntsc -paletten <palette path>/OlivierN.act <PAL rastaconverter XEX>. This will display a PAL image using the NTSC palette, OlivierN. The colors will be wrong and they will show you what I see on an NTSC monitor/TV. There may be equivalent command line switches for Atari800Win Plus but I wouldn't know what they are. Now try it again with one of your NTSC XEXes. Be aware blues are shifted slightly toward violet in Atari800 emulator but look better on my monitor and my TV. All other colors look much better, more natural. OlivierN palette is a compromise for me but seems closer to reality than the other NTSC palettes I have tried.. If you think all of this is all frustrating count youself lucky that you didn't live with NTSC encoding. It was nicknamed "Never Twice the Same Color" for good reasons. [EDIT] p.s. I just remembered a good example. One of your earlier pictures, AUTUMN.XEX, all the leaves are green here.

emkay Posted November 19, 2015 Share Posted November 19, 2015 For the palette change, it would be more useful to have a tool that analyses the RP File and makes it possible to change the colour values there. Colour manipulations of a still image were also possible. 1 Quote Link to comment Share on other sites More sharing options...

Xuel Posted November 19, 2015 Share Posted November 19, 2015 For the palette change, it would be more useful to have a tool that analyses the RP File and makes it possible to change the colour values there. Colour manipulations of a still image were also possible. This is not possible in RastaConverter in general because a single CPU register load may be used both to set a GTIA color register and also set a player's X position. In other words, the program might find a case where the color value it needs also happened to be the value it needs for the X position of a player so it just issues a single LDX/Y/A for both. So changing the color would position the player incorrectly and vice versa. That being said, these cases are probably rare for many images. BTW, I'm aware that RastaConverter doesn't specifically look for these shared register values. It just tries billions of random kernel program mutations and selects the ones that give the best results. 1 Quote Link to comment Share on other sites More sharing options...

Synthpopalooza Posted November 20, 2015 Share Posted November 20, 2015 (edited) OK, monochrome test ... what would Rasta make out of this? This requires some very subtle gradation. I did these two attempts, in the ICE modes MIN (12+9) and M0 (0+9) and got these: abstract cubes - min.obx abstract cubes - m0.obx For the M0 render, I rendered the hi-res Graphics 0 source from GIMP using positioned dithering. This introduces artifacts on a standard CRT monitor. Would be interesting to see how Rasta's 8 greyscales compare to this.

I found no dithering gave too little gradiation. It was nearly identical to your min conversion. It's looking really nice - only a few hundred thousand iterations, and already has a normal distance of 4.5. I'll let this go for a while. For now, here's a preview: Quote Link to comment Share on other sites More sharing options...
Synthpopalooza Posted November 20, 2015 Share Posted November 20, 2015 Indeed ... I might try a dither in GIMP for my MIN conversion, maybe. GIMP allows for positioned or floyd dithering so it may be a place to start. Quote Link to comment Share on other sites More sharing options...
