The Great Orion Nebula on Dry Plate.

 

Replicating Henry Draper's 1882 photograph.  I hand-coated a small, 35mm format dry plate with ASA 25 Orthochromatic emulsion that I make and loaded it in a Nikon FM3a. 

 

1 hour exposure using Vixen VC200L-DG 8" f/6.4.  Shot during dinnertime on 17 February 2021. 

Developed in D19.  Scanned, processed, etc. 

 

The dynamic range of dry plate emulsion is so great that I was able to scan the plate twice:  Once to capture the faint details and then with different settings to capture the bright core.  Combined in photoshop.

It is truly back to the basics, amazing!

 

Thank you for sharing,

I graduated from MS State with a degree in fine arts, focus of photography, as well as painting.

 

That was 1993, so digital was either expensive or non-existent, I can't remember which.  We were assigned Pentax K1000s to do all our camera work and we also had to develop our own film and prints (and buy expensive chemicals!) in the facility dark rooms.  My second semester professor was a real kook, but she encouraged us to do the inconvenient and the difficult.  We tried to do glass work in large format as well.  We each got to use the 8" Hasselblad for 1 week each semester and I SO VERY MUCH wish I'd been into astronomy then!

 

I can appreciate what you're doing, so THANK YOU for doing it!
