Maybe not so much as, at least for PAL guys, colours 8 and F are equal so there's only 12 missing.

The nice thing about these images is that they can look just as good on PAL or NTSC, who's to say which colors are "off" with all the different colored coral. it's not like a orange tiger looking pink, for an example.

Maybe I will have to make an exception with these and do NTSC versions and see if we can pick up those 8 missing colors...

Rainbow Reef more 8colours on NTSC but doesn't seem to be brown 1&F thing.

I'm now with just a small display old mobile phone and can only see one each time and zoom but it seems that NTSC is a bit messed pixels and lines compared to the PAL one that is much more clear and all stuff good and better defined.

I'll download later the two on the computer and put them side by side but I'm thinking that you'll may get the same badly NTSC looking on the other twoo...

I've felt that the NTSC images, for the most part, came out less defined than PAL images when I was doing them all side-by-side. NTSC always had 8-12 more colors represented than the PAL, but it was usually less defined. When I first started, I made a comment about NTSC having more colors, but asked a rhetorical question if that made the images any better. There are always the odd exceptions, of course.

Yes, you're right. Now I remember you said that and that you'll not do more NTSC or was only if people ask and/or you think it deserves...

And, by the way, these 240scanlines aren't possible to see all the picture on a NTSC tv display that I think the maximum is 224 that cuts 8 at the top and the same 8 at the bottom.

I wondered about that, I didn't think NTSC could do a full 240. If I do more NTSC images, I'll remember to zoom in and crop accordingly, it may help image definition slightly.

Here are some conversions of classic Atari ST's Spectrum 512 art. 512 color palette, possible 512 colors on-screen, up to 16 colors per scanline, 320x200. Similar in some ways, with similar restrictions to the use of color, to Rastaconverter on Atari 8-bits using DLI's, VBI's and players. Of course these were pulled off the Internet, already converted to .gif or .jpg or .png from the Spectrum format. The first pictures are Spectrum 512 originals, then the Rasta output.png's next.

Humm... I didn't like these late ones much. It's probably because of the ST mode that 16colours per line that can't be translated well to A8. Doesn't Rasta Converter only can get what, GR.15 4colours and more 4 from the PMGs makes 8 maximum per scanline that is half as ST 16 or it also does mid-scanlines colours changes for more?

Since it's not really a direct translation from a Spectrum 512 format (.SPC?) to and Atari format, I don't think that has anything to do with it. Not that the Atari has an actual image format like Micro Illustrator's .MIC or whatever, that uses the sprites. The best Atari 8-bit has in this resolution (outside of Rasta .xex's) is Rambrandt that uses DLI's but only 4 colors per scan-line, or one of those TIP/HIP-like software modes that can use around 64 colors. It changed from a .png output into and executable .XEX.

 

The Spectrum 512 images have already been changed to standard image formats, from a palette of 16+ million for the most part. If you save the original image posted above of the woman with sun glasses, and view it with Infraview 64 and check out the info menu, you'll see it says that image uses 49,767 colors(so 512 or less colors were converted to 49,767). The original image viewed on an Atari ST will have less than 512 colors, and would probably translated better than anything else if we could directly use Spectrum 512 images (.SPC?) in Rastaconverter; it's easy to quarter the palette and half the horizontal resolution and number of colors per scan-line, than reducing from 49,767 colors and half the horizontal resolution and a decimal point fraction in color reduction.

I think it's just my fault, not being used to how to "treat" Spectrum 512 pre-images going through the Rasta grinder.
