Re: Low-res screenshots
Thanks for the offer, Ronan, but I really want to try the photographing route first; the internet is sadly lacking of this even today. That sample is not mine, but I like to think I can get a result like that with a bit of practice (and a better camera). I indeed believe that 15-kHz BVMs are not good for gaming in general. Over 600 TVL you get too-evident black lines which go against the intelligibility, so yep; well-calibrated mid-to-low-end PVMs/mid-to-high-end Trinitron TVs (or good shadow-mask monitors) is where it's at, when we're talking low-res gaming. As for curvature, I'm not sure, to be honest. Most likely its effects can't be properly simulated, so why bother then.
If I recall, you tried the printed-mag effect with direct-feed screens, but what about subscaled and resampled photos? Do you think that this:
...can have with Photoshop, not just better focus, but a texture like the Sailor Moon screen posted above?
My non-answer to the interlace issue -- I wouldn't bother since interlacing was almost never a desired way of displaying video games (that is, if the devs had had the technology, they would have used 480 progressive). In other words, 480-P is, most times, the proper way of viewing 480-I. Technically it sure is -- the former indeed re-builds the picture which was broken for technological reasons. So I'd just use the progressive version of the picture.
And when coming down to the meaning of "screenshot", you end up with "still image", so trying to mimic the alternate scans (or, better put, its effect), will result in a "video", not a "screenshot", if that's what you mean with "combine two consecutive fields". Even if you're fine with a video, I don't think you can get something palatable nor faithful, yeah.
But if you're accepting a video, then why not an actual photograph of the interlaced picture -- you'll lose the flickering (though it is said that there were monitors quite good at eliminating the flickering -- I don't think I ever saw one), but the rest of the effects will be there. If there's no possibility to take photos, then you should simulate those effects on the direct feed screenshot (blur and de-focus, essentially), keeping in mind that you should start adding alternate black lines much like you did with "low-res" screenshots when multiplying your 480-lines screen in order to avoid blocky graphics, but you should also get them almost invisible, whatever it takes. Not easy, indeed.
On a 19'', 1280 x 1024 LCD, I get this:
The latter is clear-type crap which I can't understand how anybody can be happy with (notice this goes only for the smaller fonts; smoothing does improve the bigger ones, and that's what WIN XP did). I'm sure it'll get less crappy with higher res, but how many people use over 1080 these days for web browsing? I'm more and more inclined to design and post the new site as .PNG pages, I won't lie.
