• Hacker News1The 'Toy Story' You RememberToy Story originally looked different than today's digital versions. In 1995, Pixar had to print every frame onto 35mm film since theaters couldn't display digital files. The studio designed colors knowing they'd change on film - greens darkened, blues needed less saturation. This created a softer, grainier look with warmer colors compared to today's crisp digital transfers on Disney+. When DVDs arrived, Pixar began direct digital transfers, eliminating the film middleman but changing the movie's appearance. The same transformation affected Disney's 1990s films like The Lion King and Mulan, which were also designed for film but now exist primarily as digital transfers with altered colors and missing texture.Intentional compensation in film production:Animators deliberately oversaturated greens in digital masters to compensate for 35mm film's color characteristics. This "scaffolding" created unintended bright colors in later digital releases, highlighting the challenge of distinguishing temporary fixes from final artistic intent.Film-to-digital transfer complexities:The digitization process involves multiple variables - scanner quality, telecine machines, dust removal, and color grading decisions. Each step affects final appearance, making it difficult to determine what audiences originally saw versus modern interpretations.Preserving authentic viewing experiences:Similar to retro games designed for CRT displays, films were created for specific projection systems. Fan preservation efforts through scanning and piracy often better maintain original artistic intent than commercial re-releases.
• Reddit science1Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks.Misleading title scope:Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist:A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions:Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
