Welcome
The term "Framed" refers to the act of enclosing or presenting something within a frame, which is a common practice in photography to enhance the visual appeal of an image. "Shot" relates to capturing a photograph, often used to describe the act of taking a picture. Together, "The Framed Shot" suggests a focus on both the artistic presentation of photographs and the moments captured, implying a professional and curated approach to photography. The name evokes a sense of artistry and attention to detail in the photography business.
Light Pollution
Light pollution filters are designed to reduce the effects of artificial light sources like streetlights and city glow in night sky photography. They work by selectively blocking or absorbing specific wavelengths of light emitted by common pollutants like sodium and mercury vapor lamps, allowing the light from celestial objects to be captured with greater contrast and clarity. Most light pollution filters are engineered to block wavelengths between 570nm and 620nm, which correspond to the yellow and orange parts of the spectrum emitted by sodium vapor lamps commonly used in urban areas. Some filters, like the Optolong L-eXtreme or the IDAS NBZ-II , are designed as dual-band or multi-band filters that isolate specific emission lines from nebulae, like Hydrogen-alpha (H?) and Oxygen III (OIII), while blocking other wavelengths, including those from light pollution. Filters block some light, which may necessitate longer exposures or higher ISO settings, potentially leading to increased noise in images. Low-quality filters can introduce unwanted color casts or artifacts like flaring and ghosting into the images. The best filter depends on factors like the level of light pollution, the specific celestial objects being photographed, and the type of camera used (e.g., DSLR vs. dedicated astronomy camera).While helpful, light pollution filters cannot completely eliminate the effects of severe light pollution, and observing from truly dark skies remains the ideal scenario for astrophotography.
