Playing around a little with some neutral density filters that I had picked up a few years ago and never really used. Taken with a 0.9 filter which is similar to an extra 3 stops.
For this shot I wanted to find out how the ADOX CHS ART 25 film would handle the reciprocity failure; you know, for longer exposures, the law that states that if you stop down the lens one stop, the exposure time doubles doesn’t apply any more and you will need to add extra time to get the correct exposure. The ADOX website states that that film is “generous when underexposed or with regards to reciprocity failure” but I had to find out what that really meant and if there were any pleasant surprises linked to this. The 20 second exposure of the photo above appears to be close to correct and the light coming in from the left is pleasing.
ADOX CHS 25 ART at EI 25, developed in HC-110 dilution E for 10:30 minutes. Agitation: 2 inversions every 30 seconds.
