I cant seem to see the image. It just shows me a tiny tiny tiny thumbnail saying HT? something like that at least.
But yeah dont use any of the Scanlines tutorials they arent realistic at all...and were only nice when we had to worry about bandwith (save the image as gif..and yay! Size file cut in two
At any rate, do a blending of several blending mode of your main image, with different opacities and different noise/wrap put on them, that;s what is going to work the best...
Im thinking they have pictures of tv screens up on image*after. You might want to check that out. (or was that on Stock Inertia? Check those two and search for TV )
