1st time with Pan F+ - what happened?

[akaa]

So I developed my first roll of Pan F+ last night in D-23 1+1 for 8.5 minutes @ 20C. It was the second roll through 500ml of working solution. the 1st roll was Acros 100 and it turned out as expected. The Pan F roll had no edge markings or frame numbers, and the negs look severely under exposed.

Its definitely possible that I under exposed the film, this is my first time with something this slow. The odd part is the edge markings and frame numbers. Is that typical with Pan F?

I'll scan a strip a little later, I need to find the cables to hook up my scanner

First D23 won't give full box speed and secondly the D23 would be partially exhausted both factors contributing to under exposure as well as underdevelopment.

And third, PAnF needs more developing time than what Ilford says on their boxes : this is for PAnF, FP4 and HP5 (moreover in D76)

I went with the time at the Mass. Dev Chart. I figured I should have added a bit more time, but from the looks of these, it would have needed ALOT more. I should say I haven't been using D-23 until recently, and before that D-76. I am used to running 2 rolls through D-76 in the same manner without much problem, and figured I could with D-23 as well.

Thanks for the input guys!

Did you rate the film at ISO 50?

[akaa]

Yes, and I bracketed several shots.

Inside or outside photographs?

Yes, and I bracketed several shots.

First time I used it I either rated it at 50 or 32...probably 50 but I do remember I got thin negs.
I bet it's closer to ISO 25 in most developers realistically.

Well, the bracketed shots are better, but the developer must have exhausted on me for the edge markings and frame numbers to not show up?
