It is overdeveloped?
are you sure you are 1:100?

1:100 stand-development assumes a certain tank size (usually around 500ml). I recommend not to calculate like this, but rather 3ml Rodinal per 135 roll for an hour stand. Otherwise you risk over/under-developing, depending on tank size.
Again, as said above, I find semi-stand more predictable with similar grain results.

I have been workng the hell out of my rodinal stash!
Fellow RFF member Juan went above and beynd to help me in the right direction with the rodinal; thanks again Juan!
Using what he showed me+ my own experiments I think the key to rodinal is getting the correct exposure starting with the film speed, coupling that with the correct film speed based on the light conditions and using the right amount of time in rodinal to match condition 1+2.
Yesterday I got a new mamiya 7. I needed to try it out. I shot one roll of tri-x at 200 very soft light rodinal for 22 minutes, another roll of tri-x at 100 outdoors in very harsh light rodinal for 15 minutes and a final roll in/out doors in very low light at 800 rodinal for 30 minutes.
All 3 rolls have about the same density on the negatives
Oh, that's great, David! Well done!
Cheers,
Juan
