<Tears of the Times: Color CRT TV>
Color cathode-ray tube television, for people all over the world, is a precious memory. The imaging principle of color cathode-ray tube television is very interesting. It utilizes electron beams to bombard phosphor materials on the inside of the screen, causing them to emit different colors of light. Specifically, electron beams are shot out from electron guns and focused into color cathode-ray tubes. Inside these tubes, the electron beams bombard red, green, and blue phosphor materials, which upon impact emit different colors of light. These lights are then combined and modulated to form a complete color image.
Color cathode-ray tube television became popular worldwide in the 1970s to 1980s. At that time, with the continuous development and advancement of television technology, color cathode-ray tube television gradually replaced black-and-white television as the primary device for home entertainment. With the continuous improvement of television manufacturing technology and cost reduction, color cathode-ray tube television gradually entered more households, becoming an integral part of people’s daily lives.
However, with the continuous development of technology, new types of television technology such as liquid crystal displays (LCDs) gradually replaced color cathode-ray tube television. The disadvantages of color cathode-ray tube television such as large size, heavy weight, high energy consumption, and radiation issues became increasingly apparent. At the same time, LCD and other new types of television technology surpassed color cathode-ray tube television in terms of picture quality, sound effects, and functionality. Therefore, color cathode-ray tube television gradually withdrew from the historical stage.
Despite its retirement from history, color cathode-ray tube television remains a symbol of our cherished past. It accompanied us through countless joyful moments and witnessed our growth and changes. Color cathode-ray tube television allowed us to feel the charm of technology and understand the importance of family and friendship.
Color cathode-ray tube television had a profound impact on television culture. It propelled massive changes in the production and dissemination of television programs. The advent of color cathode-ray tube television made television programs more vibrant and realistic, providing a more immersive viewing experience for viewers. Additionally, color cathode-ray tube television contributed to the development of film production technology, as many film works were disseminated through television to a wider audience.
Moreover, color cathode-ray tube television had a significant impact on society’s culture as a whole. It became one of the main channels for people to access information and entertainment, altering people’s lifestyles. Through television, people could learn about news and cultural happenings all over the world, broadening their horizons. Furthermore, color cathode-ray tube television contributed to the rapid development of advertising, music, fashion, and other industries, contributing to the prosperity of social economy.
In conclusion, color cathode-ray tube television had a profound impact on television culture and even human culture as a whole. It not only changed people’s lifestyles but also propelled the progress and development of society’s culture.

This LoRA is created using the differential extraction method, relatively pure, with minimal impact on other content;
This LoRA does not require trigger words and is mainly used for overall artistic style adjustments;
The LoRA uses majicMIX realistic Orange Wheat Realism_v6 for the base film. Of course, I have tested it and it produces good results for anime-style or realistic models such as AWPortrait_v1.3, AWPainting_v1.2, Dark Sushi Mix Big Sushi Mix_BrighterPruned,万象熔炉 Anything V5V3_V5[Prt-RE], etc. ^_^;
Recommended iteration steps (Steps) are 20~40, but it’s not discouraged to go above 40 (unless you have a 4090T_T);
For the sampling method (Sampler), the DPM series or the base film author majicMERJIC recommends Euler, restart;
Recommended dimensions are between 512~1024;
CFG Scale, the guidance coefficient for prompt words, is recommended to be 7~12;
LoRA weight is recommended to be 0.8~1.2. Beyond 1.3, it might become too “blurry.” Of course, if you intentionally pursue a more Lo-Fi effect, it’s also acceptable ^_^;
As for High-Resolution Fix (Hires. fix) and Tiled Diffusion & Tiled VAe, well, they can be used, but the original intention of this LoRA is to deliberately create a retro Lo-Fi effect through “adding noise” (you know, influenced by the TV technology and signal transmission conditions of that time, the video sources we watched on color CRT TVs in our childhood couldn’t even surpass 480p^_^). High-Resolution Fix (Hires. fix) and Tiled Diffusion & Tiled VAe tools have the ability to increase resolution while performing high-definition restoration at the same time. Using them will weaken the LoRA effect, contradicting the original purpose of creating this LoRA. So, with the aim of not affecting the LoRA effect, any magnification behavior is not recommended. However, if you insist on enlarging, in the SD webui, I personally recommend sending it to post-processing for proportional scaling;
Finally, I strongly recommend using After Detailer. The reason is that this LoRA inevitably affects the facial features of characters when adding noise Lo-Fi to the overall image. Therefore, to maintain the appearance of facial features, it is strongly recommended to enable After Detailer!!!
