I've been trying to figure out a way to show people the massive difference between using the standard RF feed on a TurboGrafx and using a modified (mod'd) TurboGrafx with a Composite signal.

Sorry about the reflections in all of these.  They were taken at the same time of day on the same TV with the same color/bright/tint/etc settings for both the RF feed and the Composite feed.  Please also note that the horizontal dark/light bar is an artifact from taking a photo of a TV.

It's hard to capture in a photograph, but the RF feeds have a lot of static in them (if you're looking at a black screen, you'll see white dots popping in and out.) and the RF feeds also have wavy lines that alternate directions, etc, as the audio and other environmental factors interfere.

Below is an RF feed:

Below is a composite feed.


Here's another RF photo:



And another composite photo:


As you can see, the colors are a lot better on the composite feed as well.  Some day I'll figure out how to get the large horizontal bars out of the picture.  I think you might need a special camera to do that or something.
