Some E200 Slides at GSSP 2014

The last two nights at GSSP 2014 I was using one of the Pentax 67 cameras to work on two rolls of Kodak E200 film I'd brought.  I was able to finish one roll with minimal issues, but the second is still in the camera, half complete.

One of the exercises I'd done to help use the film while under the stars with good transparency and darkness was to get multiple exposures of the same region of the sky.  Adin, CA does not have much airplane traffic, so being vigilant and watching for streak-causing planes was not as much of an issue. 

To fill the experiment/challenge, I snagged 3 frames of the Sadr area in Cygnus.  The field of view with the 200mm lens allows the whole complex of Ha nebulosity to shine from the North America Nebula through to the clouds around and past Sadr.  If I offset the frame a bit more, including the Veil would be possible, too.  Would be very easy with the 165mm lens.

After "scanning" by taking pictures of the negatives on a light source with the Pentax K10D camera with SMC PENTAX-DA 1:2.8 35mm Macro Limited lens and AF540FGZ flash in PTTL mode, I had pretty reasonable files to use.  Flatness of the film was an issue in one case and I had to flip it over.  Also, I kept the film in the protective contact sheet/sleeve as it seemed to not be an issue.  However, what was an issue was flare from the light spill around the dark areas of the slide.  I may need to rescan by masking off a piece of glass.

Brought the files into LR where I fixed keystoning from not having the film and camera parallel.  Then exported to TIFF files and ran PixInsight's Gradient Mosaic Merge tool.  Very slick tool and it gave really good results!  While in PI, the picture was increased in contrast and saturation slightly before working in LR again for vignette work and slight white balance tweaks.

In the end, I like the picture and am pleased with the results.  I can see now that future work will probably have 3 or so images of the same area to improve film grain results.
