Taking Decent Photos of your CRT TV Screen

Taking Decent Photos of your CRT TV Screen

6 comments
Recently I was prompted to try taking photos of the TV which currently serves as a monitor for my XT, because reasons (which may be made clearer in the future if I'm not lazy and/or distracted by other things).  After much trial and error, I think my current results provide an accurate representation of what's actually visible on the screen. Getting there wasn't exactly a walk in the park, so perhaps this post could prove useful for someone. ...
Getting Optimal Apple ][ Screenshots w/NTSC Emulation

Getting Optimal Apple ][ Screenshots w/NTSC Emulation

3 comments
A while ago over at MobyGames, AppleWin NTSC was recommended (okay, by me) for obtaining Apple ][ shots.  However, it's a bit of a pain to use, since the built-in screenshot function doesn't work.  Also the NTSC output is still not *quite* ideal (there's some ghosting/ringing going on, and black/white areas are somewhat 'noisy'). Thankfully Michaelangel007 has provided a newer build which addresses both of these issues.  The full discussion is on github, but here's a quick-start guide to make your lives easier and your screenshots better: ...

8088 MPH Final: Old vs. New CGA (and Other Gory Details)

At long last, the final version of 8088 MPH is out.  There's a very nice rundown of the fixes and changes in Scali's blog post; much of the visible (i.e., graphical) portion of those changes involved making the demo compatible with all IBM CGA cards. The party version targeted the earlier, pre-1983 revision of the IBM CGA card (or as we've come to call it, "old" CGA).  This was partly because we had better data for this model: reenigne owns such a card, and he had been working on some of these tweaks long before we decided to make a demo about it. ...

By now you may have heard of the 8088 MPH demo, the winning entry in Revision 2015's Oldskool Demo compo this month. It's been my pleasure to combine efforts with the likes of Trixter, reenigne and Scali to make it happen - not only did I get the opportunity to work alongside a bunch of extremely talented wizards of code, we also achieved what we set out to do: break some world records on the venerable (and yet much-maligned! ...
Using Photoshop as a CGA Bitmap Paint Program

Using Photoshop as a CGA Bitmap Paint Program

Adobe Photoshop has an "indexed color" editing mode for palettized images, but let's admit it, it sucks.  No layers, no anti-aliasing, no filters, no (easy) dithering, and so on so forth: clearly, it's no substitute for DeluxePaint II, Autodesk Animator, or even PC-Paint.  There are modern, free and open source packages which explicitly seek to fill this gap, but just for fun, can Photoshop's limitations be subverted? Recently, at least by my glacial standards of time, someone (thanks, Andrew! ...
