My first real trip out with the Sinar I took 4 photos this is the first I have developed and under developed because I got my testing a little wrong, but still have with the result.
The print has a lot more detail in the blacks I could just not get the scanner to grab them. So the print looks much nicer. Also the water I put on zone 8 but after short dev it came in at zone 6 :s
So I pretty sure it's under dev, but out of interest what makes you say under exposed?
