| By pictures Cyan means like digital photos, by computer gfx he means like things made with MSPaint, PaintShopPro, PhotoShop, etc. and they can't just be "edited," they have to be made completely in those programs to be computer graphics. |

I never distinguished imagery to being "computer gfx" and "photos". Maybe it's because I am creating completely computer generated images which are as realistic as possible. With some of my best architectural visualizations you can really hardly say, if it's computer gfx or just a simple photo. See yourself at pages of my studio at www.caadg.com.
And maybe it's just me, not knowing PNG so well... I understand it like being an alternative to GIF (which means you save space by lowering colors). Photoshop's PNG has almost no options... |

I made a very nice post explaining PNGs very well, which also includes a link to a good Photoshop Plugin for better PNG options.
So you know: PNG stores each pixel exactly using lossless compression. Its actually better for computer images that other formats, as it lets you use alpha transparency, so you can have your image blend with any background nicely. |

Mine GO BOOM: thanks for that plugin link, now I can extend my possibilities in finding the lowest filesize with best image quality. I'm not going to trash talk about well known things for GFX guys (for few of us maybe) here. I believe that any really decent graphics maker should always try which format from those supported is the best for particular image situation. That's why we got Save for Web window in Photoshop - you can easily switch between GIF (lossless compression) and JPG, or play with different dithering techniques.
Very valid advantage for PNG is that Continuum client kinda likes it, from what you have said at that thread. But you also said that an advantage of PNG over other formats is its support of an alpha channel. How can I use it with LVZ screen objects for example? From what I know, client renders pure black as transparent, and some RGB 28,28,28 (?) as cute semitransparent checker. About 16 or even 32-bit modes I know nothing - still kinda waiting for all players getting modern GFX cards to get decent FPS in these modes. (BTW, I work with alpha from the day I was born I believe, if I could really pass those perfect antialiased alphas from 3ds max to Continuum...YAY  )
Anyhow, thanks again, your da man 
Akai: thanks, yes I am proud to have the degree at Slovak Technical University, faculty of architecture

can't use the alphas with Continuum
solid black rgb(0,0,0) is only transparent across all color depths, if you have say rgb(7,7,7) it will be transparent in 8-bit, but will make a solid color in 16-bit
and yes, the only way to have semi-transparent (that I know of) is to alternate solid black with another color each pixel (checkerboard) |

Everyone should always open their renderings in Photoshop for very close inspection and color space conversions, before saving them to Continuum folders. So any RGB(7,7,7) becomes pure black in SS palette.
But I meant dark green spot in SS palette, which seems to be rendered as checker by the client.
Anyways, it doesn't help too much, since creating ships (or any other overlaying object) with crispy, yet still clean "antialiased" edges remains a tricky task. From my experience you have 2 options:
1) antialiased edges against black background - looks perfectly smooth against stars, but try to fly over any brighten area and you find yourself laffing at that ugly black cloud around your ship
2) hard edges - intact to brightness or color of the background, but pretty jaggy looking
one worst of another  |

agreed.
after all, too bright solid areas are not so lucky decision for a background |
