Any help would be appreciated.
Thank you</p>

Sorry to hear you feel confused - this is simply an experiment in 3D printing that I wanted to share. As mentioned in other comments, it does look like inverting the photo would yield a better result. In any case, I'm very happy with how it came out, and it does happen to stand up straight on it's own. Given you seem to know so much about this, I'd love to see your version of how you think it should look! Cheers :)</p>

If you were aiming to print a picture from the 80's it looks good.
If you were trying to make a lithophane try printing the whole thing stood up!
Depending on how you get the stl file, as in from a website generator or you
import a jpeg and do it in Cura. some require you to print the lithophane stood
upright on the z axis, where Cura requires you to do it flat.
Also on the website, I think, you have to make the image positive.
and in Cura you have to set darker is higher when you import your jpeg.
Otherwise you get the negative effect you have here. Hope this helps!</p>

I have heard that different materials print better on different printers so I can't comment if this is the best option, but it's what I used. Using a smaller filament weight or finer extruder would allow for more detail in your print. The smaller the layer height, the more detail as well. I used a generic LulzBot Profile in Cura for my materials to generate my g-code: https://www.lulzbot.com/taz-cura-profiles. High precision printers will offer a more traditional lithophane feel, while the desktop variety will be a bit more crude. A light color filament is always best for this as light needs to leak through, so try to avoid anything that prints super opaque.<p>Hope this helps!</p></p>

Printer settings such as fill density, shell thickness, etc.?</p>
