1+1+1=1

I’ve mentioned before that I keep the process of digitising my negatives as simple as possible. However, it is not that I am a Luddite nor that I am an incompetent, I simply prefer fresh air to a computer keyboard. My purchase of the RSS 6×17 though has meant I have needed to rethink this a little as the negatives are so large I waste over half of the sensor if I try capturing the whole negative in one go.

My previous post mentioned that I had stitched two “negatives” together to make an image with a wider field of view by harnessing the power of having a camera with top and bottom shutters. It didn’t however mention that the two files I used were each comprised of three parts which were also stitched together.

My technique was essentially the same as I would use to capture a digital panorama in the field adapted slightly for the new purpose. I adjusted the height of the camera on the copy stand until the vertical side of the negative completely filled the frame. I then made three exposures, moving the negative between each to ensure I captured the whole of the 6×17 negative (see below). Three exposures gave me a good overlap between each negative which helps the software with the stitching. Incidentally, I had photographed each portion of the negative with the same settings on the camera and at this stage I have not made any adjustment to the RAW files.

Three digital files cover the whole of the 6×17 negative

Selecting the three RAW file in Adobe Bridge I then selected the Tools menu and then Photoshop and Photomerge from the sub-menus.

Tools > Photoshop > Photomerge

I then sat back and let Photoshop do its magic and after a few moments it presented me with a stitched file with three layers. It appeared to have done a very good job of aligning everything and so I simply flattened the file and processed it as normal.

Three “scans”, one stitched file and the final result

Now, there’s no point asking me for optimal settings etcetera as I won’t know the answer! This method was intuitive and worked for me. I am sure that I will take more notice of discussions on stitching in the future so may well improve on this methodology but for now it works for me!
