On Friday I decided to shoot a roll of Kentmere 100. I loaded my Nikon FM3a and attached the 50mm 1.8AF lens. Because of the changing light conditions in the Northwest, I shot the film according to need. I shot the film at box speed, at 200, 400, and one shot at 800. I then developed the film in R09 One Shot at 1:100 @20C for an hour. I agitated the film the first 30 seconds and then 5 seconds at the 30-minute mark. This is Stand Development. The long time period allows the developer to deplete and it does not matter what speed you shot the film. If I shot the film only at 100 I would not have used this method. The stop sign was shot at 100 and the fallen tree was shot at 400. The next 2 images were shot at 100.
This tree was shot at 800.
The next 2 at 400.
And finally, No Smoking shot at 100.
People use different times and formulations, and differing agitation methods, but generally, a long time period is used when developing the film.

Kentmere really seems like the best bang for the buck.
Your results with RO9 seem about what I would expect — a little more contrast and grain, but nice blacks. I’ve liked the film with PMK Pyro, but the loss of a stop is a little too much, so I mostly now use L110 at box speed. I look forward to seeing where you go next.

I shot a roll of Kentmere 400 today at 400 and will probably develop it in D76 1:1. We will see what happens.

Remarkable. I had no idea.

I always wondered about “stand development”. Do you need a particular developer for this or any developer could work (with, perhaps, minor issues)?

Here is a youtube video about the basics of stand development using either Rodinal or HC-110. https://www.youtube.com/watch?v=wsQYRpRhDcI
