canadian pharmacy premarin cream In many ways exploring the night is similar to an adventure trip to an unseen cave, or reaching the top of mountains where only few have experienced the amazing vista. It’s a challenge with the same taste of adventure. During the past 2 decades nightscape photography developed in me from a teenager hobby to a professional skill and an international program to show the world at night (TWAN program, founded in 2007). Nightscape photography is not only about recording a part of the outer space or our environment. It leads you a life of adventures. It becomes your lifestyle. You start working when “normal” people enjoy parties, watch TV, and sleep. But like the explorers of new worlds you will be gifted by unique experiences to share with others. Some scenes are forever-engraved moments in my memory. From the boundless darkness of African Sahara when the summer Milky Way was arching above giant sandstones to the shimmering beauty of the Grand Canyon under moonlight, or heavenly curtains of dancing aurora in all colors over Lapland, and crystal clear skies of the Himalayas.
level 4 options trading approval Nightscape or starscape photography where the Earth and sky are framed together with an astronomical purpose is also known as “Landscape Astrophotography”. These images resonate with viewers on an instinctive level and they spark the imagination. Familiar landmarks provide a context viewers relate to, even among city dwellers who have never gazed in wonder at the natural starry sky. Thanks to the fast developing technology of DSLR cameras starting nightscape photography is now very easy. But some knowledge about night sky and practical astronomy is essential to plan, in order be ‘in the right place, at the right time.’ Planning is based on ideal weather and moonlight condition. Factors such as geographic location, altitude and temperature, local topography, and light pollution must be considered in preparing for a photo shoot. Many things can go wrong at night with equipment and environment. Inform someone about where you are going. Avoid doing night photo shoots alone in remote locations. Being in a small team of two or three is the most pleasant, and larger groups cause issues such as too many tripods, similar image results, and moving flashlights in your photos. Arrive at locations before sunset. Get familiar with the environment and obstacles around you. Always consider unpredictable issues with accessibility, wild life, government restrictions, and public unawareness of a friendly sky photographer who might be mistaken as a wandering vampire or a lost alien with a ‘red laser’ coming out of the head! You are then in the worst place at the wrong time. Such risks are much less when you arrive at the site earlier in the day. I have encountered security and police many times in my night shooting around the world, but usually it ends up being a fun stargazing class under stars for the officers.

While the color of day-time nature is evident most photographers are not familiar with natural colors of night sky and often shift white balance or apply saturation in extreme ways that change the rules of nature! A general example is the post processing attempt to remove red cast of light pollution or the natural airglow which results in saturated blue Milky Way when it should range from yellow (specially towards the galactic bulge) to almost colorless and pale-blue (in areas with rich young star clouds). To those who are familiar with natural night sky colors these changes look as odd as seeing a blue lion or purple giraffe! I also recommend avoiding the habit of ‘over-cooked’ processing. Nightscape imaging is a part of nature photography where the originality of the scene and the story is a value. Composite images made with different lenses and exposures or a montage of day-time and night-time frames has their own value in digital art but they are usually not recognized as an actual photograph.
