There's no set time. I did one of my best images today with only 150 million iterations. I have had stuff run for over 5 billion and they don't look half as good. I also unfortunately cannot explain what kind of picture will work, because I often think something will look great and it can't work. Just takes a lot of time, patience, and experimentation.

Indeed. Atari just cannot display all the pictures nicely because of how hardware sprites work and how color registers can be changed. After some experimenting you quickly find out if picture is promising or what changes must be applied in preprocessing to make it look better.

I had a sort of cool looking "Gates of hell" going all last night. Problem is the scaled down version looks crap @ 160 res, I could have saved the trouble by just scaling up the preview before I left it running.

Rybags is right. This conversion looks OK in just 120 million evaluations but without the ability to portray the eyes the story of the picture is missing.

What you can do is to find a mix of useful colours and possible details.

 

And, what do you think about this result?

Short reminder for those new to the thread: Please use <author>_<image>.xex as the naming convention, so we can kept the collection intact.

Man that's some pretty purple. :)

I'm pretty severely colourblind, so things like this with very high contrast look good to me.

Looks like our mistake all the time was to convert stuff from and inferior machine (C64) instead of copying from the best :-)

 

(No flame wars please, I love C64 too)

This is a picture that would look better using my ICE MIN (12+9) mode. You really need the 16 lumas of Graphics 9 to get this to work.

Hello!

 

Ready for next challenge?

 

Shouldn't be hard, I think. :)

I'll give it a shot. I'll adjust the aspect ration to get the most of the usable image on screen without squashing it.

Agree with Stephen on aspect ratio. A few attempts on a cropped section:

I'm having difficulty with this. There were a lot of jpg artifacts on the image even before rescaling it. I tried cleaning them up and some quick tweaks, but it also doesn't like the colour palette.

I'm curious, have you ever tried anything like the Enchroma glasses?

With the suit pic I think what could help:

- remove the non-white colour components from the shirt.

- make the background colour same as the most common colour within the shirt.

Never heard of them. My results from their test were:

 

STRONG DEUTAN
What is a Deutan?
Deutans are people with deuteranomaly, a type of red-green color blindness in which the green cone doesn’t detect enough green but is too sensitive to yellows, oranges, and reds.
As a result, greens, yellows, oranges, reds, and browns may appear similar, especially in low light. It can also be difficult to tell the difference between blues and purples, or pinks and grays.

I wonder about this. Particular those pictures do not fit in terms of aspect ratio and colourisation. So some external help is needed ;)

On the other hand.... such pictures would be very thankful for a "hires" converter with multiplexed PMg.
