Film Test: Fujicolor Superia 200

Here comes another film test. Fujicolor Superia 200. Together with Kodak's Gold 100 and 200, Fujifilm's Superia line prove to be useful for astrophotography.

Two photographs of the Milky Way taken sequentially. The first (left) is a 5 minute exposure at f/2, the second (right) is a 15 minute exposure at f/2.8 using a 50mm lens. Both frames are shown here as one continuous scan to show actual changes resulting from exposure. Sky glow was reached in 15 minutes @ f/2.8

This film has potential. It falls within the range of many modern ISO 100 and 200 films which have good reciprocity characteristics and color stability in long exposures.

Conditions were good, but Scorpius had not reached the meridian at the time of exposure. I had to work the next morning and needed to get the test done with!

SQM: 21.56, Temp: 44 degrees F.

The Denizens of Orion on Kodak Gold 200

A follow up image to my original test of Kodak Gold 200 last year. This two panel mosaic includes the heart of Orion, the majestic Messier 42, The Great Orion Nebula. The color response of Kodak Gold 200 over the required 30 minute exposure is about as good as any other print film when exposing brighter astronomical objects.

This image was taken in early January 2011 near the beginning of a roll of Kodak Gold 200. Such as film photography is, the roll was recently completed and processed.

Two frames (vertically oriented) were exposed and combined in Autostitch. Flat fielding was done with PixInsight using DBE (Dynamic Background Extraction). Curves and levels were adjusted in Photoshop.

High clouds bloated the bright stars.
