Tough stuff to deal with. Very high contrast. Went down to a nearby brook under ideal overcast conditions and still I had a hard time holding back the highlights. My Fm3a's meter should not of had a hard time under those conditions. Film was rated at 20 using the recommended Adox 50 developer. Suggested times are 5-5.5 minutes so i went with 5 minutes 15 seconds at 68 degrees F. There is "no" grain and a hell of a lot of detail but if I don't learn how to control the contrast then it's back to Delta 100. Maybe I'll try 4 minutes 45 seconds next time. Any user suggestions?
