Description
I see an old fashioned analog television.
" Analog (or analogue) television is the analog transmission that involves the broadcasting of encoded analog audio and analog video signal:[1] one in which the information to be transmitted, the brightness and colors of the points in the image and the sound waves of the audio signal are represented by continuous variations of some aspect of the signal; its amplitude, frequency or phase. All broadcast television systems preceding digital transmission of digital television (DTV) were systems utilizing analog signals. Analog television may be wireless or can require copper wire used by cable converters.
The earliest mechanical television systems used spinning disks with patterns of holes punched into the disc to "scan" an image. A similar disk reconstructed the image at the receiver. Synchronization of the receiver disc rotation was handled through sync pulses broadcast with the image information. However these mechanical systems were slow, the images were dim and flickered severely, and the image resolution very low. Camera systems used similar spinning discs and required intensely bright illumination of the subject for the light detector to work.
Analog television did not really begin as an industry until the development of the cathode-ray tube (CRT), which uses a steered electron beam to "write" lines of electrons across a phosphor coated surface. The electron beam could be swept across the screen much faster than any mechanical disc system, allowing for more closely spaced scan lines and much higher image resolution, while slow-fade phosphors removed image flicker effects. Also far less maintenance was required of an all-electronic system compared to a spinning disc system "-Wikipedia
This painting started out as a picture of handblown glass created by Garth Mudge of Glassworks in Winthrop Wa. Glassworks is located downtown in the beautiful Methow Valley in Okanogan County .
I painted and reflected the original image into a whole new image. I am retaining as much of the original textures as possible. I am using only the colors that originated in the picture when it was a photograph. I am using these colors as a starting point for the picture. Then I choose which textures to use to complement the colors. Then I start painting and when I have painted to my hearts content I create a new layer, reverse it and overlay it onto the original image. I call this a Reflection.
I am really enjoying using the photographs I have taken over the years as starting points for new individual artworks. I lover the tools that are available to help us create ever new and changing art works. A Wacom tablet and Photoshop software have opened up a whole new world of creative options for me
