Response to Reciprocity Effects on APX25

Reciprocity failure tend to increase contrast of shadow zones selectively. This is in contrast to sunny day's photo, where you determine exposure for shadow zones and you'll get excessive contrast in highlights. For this reason, I find Microphen very effective for nightscape where I often expose for dozens of minutes on TMX. I don't use APX25 for nightscape but as a rescue I see why not Microphen or XTOL doesn't work the same way. I'd use 1+2 or 1+3.
