Grandson watching cartoons when I had the thought of trying to capture an image from the TV.
Had to use lots of noise reduction to get all the lines out of the TV image.

Colorful, anyways.

What a delightful photo! Super-cool idea.

A quick Google search suggests you can avoid the lines if shooting 1/30 sec or slower. I'm curious if anyone else has tried? (your image has exif removed so I don't know what you used)

Thanks for posting!

Thanks kpmac

Thanks Linda ... I tried shutter speed from 1/30 to 1/120, seem to look all the same to me. Camera was on a tripod.

Thanks kinievans.

In old versions of Photoshop there was a plugin that did Fourier transforms and inverse transforms. The FT will take an image with regular patterns and give you a transform image that has stars (bright spots) in it that arise from the pattern. You could wipe out the stars, then apply the inverse transform and you got the image with the pattern removed. It was useful when you had something like a scan of a halftone or a photo that was printed on paper with a pattern embossed on it.

I have found a plugin for a fast Fourier Transform that sort of works but I can't get it to work as well as I had a decade ago. Maybe it's just me?

What a terrific idea. I think you should print, frame, and hang it in his room.

You did well! Great idea to have him hold a toy that looks like it came off the screen too.

The 1/30 second or slower shutter speed was required because CRT (old style TVs) had the image painted by successive scans of a light beam which was interlaced to minimize smear. It took 1/60 of a second to paint the entire screen. Faster shutter speeds introduced black horizontal bars where the screen had faded from the previous scan.
Modern flat screen (LCD, LED, plasma and OLED) devices are a matrix of tiny receptors which do not require scanning.
