GFX 100S scanned images at 100%

November 13, 2021 JimK Leave a Comment

I’ve received a request for crops at 100% magnification of some of the images that I showed you in the last post. Here they are, together with the whole frames. Note that the JPEG compression used on this site will obscure details.                      

GFX 100S

Some scans with the GFX 100S

In the last post, I walked you through my new system for digitizing silver negatives. In this post I’ll show you some scans. These are all from a series I did in the late 80s in the hills above Stanford University. The idea of the series was to explore the relationship of nature and technology… [Read More]

My thinking has been to use a GFX 100 or GFX 100S and Schneider and Rodenstock macro lenses. I’ve done some work the… [Read More]

Illuminants for scanning

October 14, 2021 JimK 7 Comments

I’ve been working away on developing a way to digitize black and white silver negatives at high quality using a GFX 100 and/or GFX 100S (I’m going to call this operation “scanning” although I’m aware that that term doesn’t really fit). I’ve reported on this blog about some of my testing of appropriate lenses. I’ve… [Read More]
