KONO B&W 400 is a nice combination with Adox Rodinal. Until zone 4 the contrast is a bit lower than normal. From zone 5 to 9 the contrast is a bit stronger than normal and from zone 9 onwards, the contrast is normal. If you want better shadow detail expose one or two DIN more (ISO 320/26° or 250/25°).
Please be sure to use the data Silversalt tested.
If you want to test KONO 400 or if you don't even know Rodinal yet, this test pack is a good choice.
