Opis: In tu je moja prva fotografija dvojnega loka Rimske ceste.

Moram priznati, da je to tehnično najtežja fotografija, kar sem jih urejal do danes, pa ne samo zaradi dvojnega loka, temveč tudi zaradi različno dolgih ekspozicij, polovica panorame posnete v astronomskem mraku s spreminjajočo se svetlobo, zvezde fotografirane s filtrom, potrebno je bilo izdelati avtomatizacije v PS, registracija zvezd, združevanje dveh razlicnih panoram itd. Za to fotografijo se skriva ogromno stvari, z nekaterimi sem se s soočil prvič, zato je bil to pravi izziv.
Odločil sem se, da izdelam kompozicijo katera prikazuje pravilni vrstni red, iz leve proti desni. Tako se na levi strani nahaja zimski lok Rimske ceste z zahajajočim Orionom, ter desno poletni lok z vzhajajočim jedrom. Vse to je bilo posneto na eni lokaciji s 6 urnim presledkom in to spontano. Med fotografiranjem ospredja ob 23ih, sem se uzrl v nebo in videl idealni položaj Zimskega loka Rimske ceste za izdelavo dvojnega loka. V photopills sem hitro pogledal višino zimskega loka, ter ga primerjal z višino poletnega loka, kateri se bo zgodil čez 6ur. Oba loka bi bila identična, zato sem hitro prenehal s fotografiranjem ospredja in vklopil Fornax, ter kamero usmeril v nebo. Poletni lok Rimske ceste je bil posnet v Astronomical twilight, jedro pa kar 20 minut čez popolno temo.
Zelo sem zadovoljen s svojo prvo panoramo z dvojnim lokom, kljub temu, da je bilo fizično zelo težko ostati tam zgoraj pri nizkih temperaturah. Resnično sem užival v izdelavi te nore panorame, ob kateri sem se naučil par novih stvari.

Description: Here is my first photograph of a double Milky Way arc.

I must admit, this is technically the most challenging photo I’ve edited to date, not just because of the double arc, but also due to the varying exposure lengths, half of the panorama being shot during astronomical twilight with changing light, stars photographed with a soft filter, creating automations in Photoshop, star registration, merging two different panoramas, and much more. There’s a tremendous amount of work behind this photo, some of which I encountered for the first time, making it a real challenge.
I decided to create a composition that shows the correct time sequence from left to right. On the left side is the winter Milky Way arc with the setting Orion, and on the right, the summer arc with the rising galactic core. All of this was captured at a single location with a 6-hour gap between, and it all happened spontaneously! While photographing the foreground at 11 p.m., I looked up at the sky and saw the ideal position of the winter Milky Way arc for creating a double arc. I quickly checked the altitude of the winter arc in PhotoPills and compared it to the altitude of the summer arc, which would occur 6 hours later. Both arcs would be identical, so I promptly stopped shooting the foreground, turned on the Fornax and pointed the camera at the sky. The summer Milky Way arc was captured during astronomical twilight, with the core photographed 20 minutes past complete darkness. I am super happy with my first double arch panorama, despite it was physically really hard to stay up there in freezing cold temperatures. I really enjoyed making this crazy pano, where i learned a few new things!

Category: 360 Panorama with double arch / Tracked / time blended

Exif:

• Sky:

1. winter arch at 11pm: iso800, f1.8, 90s, 6panels + low exposure frames for brighter sky parts ( 60s, 30s ) + lee soft 5 for stars ( iso3200, f1.8, 20s, 10s )
2. summer arch at 4:55 till 5:17am in astronomical twilight: iso800, f1.8, 90s, 6panels, i needed to change exposure from 90s to 30s because of light was brighter with each panel

• Foreground: iso1250, f2.2, 80s, 12panels
