Camera: Homebuilt 5x7 sheet film camera
Filter: None
Drive: Motorized curved-bolt
Exposure: 1x15min (?)
Film: Kodak Tri-X, 5x7 sheet film, pushed to ISO 800
Flat: Synthetic
Software: Photoshop

I was going through some old newsletters when I came across a 5x7 negative tucked away between the pages. I was delighted to find that this was my one and only picture of Comet Halley, taken on a bitterly cold winter night in 1986. I remember when I originally developed and printed this picture that I was disappointed with the focus and contrast, but I never got a chance to try is again. To recover the picture I taped a sheet of Velum to a sunny window and taped the negative to the Velum. I then took several pictures of the negative with my Canon 550D fitted with a 40mm macro lens. I did my best in Photoshop to crop out the horrible edges and the awful gradients, but it was a thrill seeing my old friend.

Same image, inverted. This makes it easier to see the tail.

What a great capture - and it's yours. I can't remember that far back.

What's I find intriguing about this image is that it had to wait until the digital age before I could really appreciate it. The original had so many problems with gradients and low contrast that it was impossible to get a good print off of the negative. I'm so glad that I found it.
