I've been working on a CRT simulation shader on and off in the past year, since the ones available were in my opinion not doing a very good job of simulating the actual look of a decent arcade-style CRT monitor. At this point, most of the work is done, the single pixel gradius stars look good, same with the various dither-based transparency effects (Sonic waterfalls, Jurrassic park snes, street fighter alpha health bars).
I have done the most I can as far as color correction goes with the reference images I could find on the net and from fellow member trap15 (thanks again!), but I still need quality reference pictures to do the final tweaking of the phosphor shape (and resulting apparent scanline thickness), color correction and gamma correction.
So what I need is quality pictures of real hardware on an arcade monitor or a good CRT (PVM and such) via rgb, 3 to 4 feet away from the screen, directly in front (no steep angles), in a well lit room and ideally without light reflecting off the screen (diffuse light or light behind the screen).
Ideally, the images would have one of these in the picture (if you're willing to go through the trouble you can pm me or ask me in this thread and I can arrange to get you one):
Failing that, if you have a decent camera (the newer high end phones have pretty good ones) you can use manual/Pro settings and set it to:
ISO 200 Film Speed
Exposure Value (EV) 0
5000k or daylight white balance
Other than that, if you have a lot of recent playtime on actual arcade hardware and monitors you can take a look at the screenshots and provide constructive criticism. If a lot of criticism points the same way, I'll modify the effect accordingly.
Here are a few screenshots of the current latest version (0.9), If you want more screenshots and details about the filter, see this page: http://stormoid.com/Cathode/cathode.html
