Sorry, no Christmas theme here yet. I was 11 years old the summer of '79, and that was the year my older brother (16) and sister (18) pitched-in to buy a 1964 Ford Galaxy 500, maroon colored, with side pipes, Kreger rims, and 8-track player and CB radio. I've been enamored by the 60's model Galaxy 500 series ever since. Here is my tribute. Sorry, I haven't found any pictures with side pipes yet.

 

59 Ford Galaxy 500. 55 colors.

64 blue Galaxy 500. 81 colors.

64 red G500. 36 colors.

65 green G500. 44 colors.

65 blue/green G500. 64 colors.

67 maroon G500. 56 colors.

67 yellow G500. 39 colors.

69 fastback G500. 62 colors.

64 custom G500. 74 colors.

Oops. Well, then, many of these images were misspelled as well. I saw both spellings and went with what I posted. I plead ignorance and bad memory. Maybe I'll post a .zip later with all names corrected.

That's a great one! At least it looks great on my PAL setup. Colors are right. Did you want me to attempt a better one? I'm not sure I could. I think maybe we could get a bit more detail just by cropping the picture a bit more to squeeze in a few more pixels of detail from the original image. I could do that with my 'Earth' image too, for that matter. I cropped to 4:3, but could zoom in a bit more.

 

Is this an image done with a standard PAL palette Stephen? How many colors were used?

Didn't really want you to re-attempt it, your image just reminded me of a somewhat visually similar, if completely differently coloured image! I'm sorry - I don't recall any of the details as I did this 4 years ago. I will assume I used whatever RastaConverter was defaulting to back when I did this.

 

I do have all the output.* files if you want I can ZIP them and post.

Posting this from the other thread. I spent zero time on this, didn't resize it myself like I normally do so it is not vertically centered. It was a quick 5 minute drag & drop operation while I was "on lunch" at work.

Wow, wait a minute there ! If there's one famous 2D game I'd have bet is impossible to come even remotely close in visuals on A800, it's Rayman.

 

How in the world can all those millions of shades approximate so well ?!?

 

Could you please spend a day evaluating this ? I'm sure I'm not the only one who just WTF'ed at the 5-minute conversion!

This is nothing more than a static image, using the RastaConvertor (PC based) image converter.

I understand, I have been following this thread last few years.

 

That's why I'm surprised the smooth transitions of green translate so well with just few iterations.

 

Can't fool the eye on large patches of low-frequency green like for example the high-frequency dragon scales few posts above.

The problem is your over assumption of the source graphics in "thousands" of colors. Yes, Rayman, using the Jaguar version for example, used a 16-bit ~65,000 color mode, but that does not mean that they used all 65,000 colors or even a lot of progressive shades. The fact is that as a resolution of ~320x225, while it could fit 65,000 different colors on screen, it's not going to happen with a real image, instead of a bunch of colors. Those greens in Jaguar Rayman are really only about, I'll take a guess, 32-shades (if you can look at it on a big screen or with a magnifying glass close-up) that blend well. So reducing that to about 8 shades really isn't that big a loss. In both cases, the human eye can be fooled into seeing more color than there really is in a given image.

 

Most of the images I download and convert with Rasta, are in 24-bit true color, but if you load them into a paint program like Irfanview 64, most of those images do not consist of 16 million colors, they consist of only tens of thousands or even thousands, only the colors needed are used. So, I'm going to look at a screen shot of Jaguar rayman with Irfanview 64 and see just how many colors are really used at once...in the image below, a Jaguar screen shot, the actual amount of colors used out of 65,000 is 243205. And I know from experience, that if you take a screen shot with a camera (not saying the image below was taken that way), it can actually add colors that are not really there! If I do a Rastaconverter image that uses 64 colors, and then take a picture of it with my camera, and then load it into irfanview 64, guess what? it suddenly has thousands of colors registering! My point being that the 243205 from the Rayman screen-shot may in fact be much higher color than looking at the screen live. it's all relative.

I wish these conversions were further along than they are but if I wait until I'm completely satisfied I might not have any picture before Christmas, truthfully.

 

These are all for NTSC and look best with the enclosed palette. They look pretty much the same on my real hardware. I hope they look as good for everyone else.

 

Enjoy!

 

p.s. I'll try to do some PAL conversions (using a default palette).
