I went today being a beautiful day (plus8 in January) to take some images. When I noticed my two Grafmatic holders already had film in it. So I exposed Tmax at EI 80 and Tri-x 320 at 200.Enyone can give me an idea of developing times for developer of choice Pyro-HD or should I use some other developer for better results? I use JoBo drum for stand or rotary development for six 4X5 sheets.

Thanks in advance Greg

for hand aggitation in the jobo tank - for (4x5) tri-x at asa200 at 70F - 9 minutes 1:1:100 - DR about 1.25 and SBR about 9 stops - It is a winning combo for Grade 2 fiber paper!

If you get a chance, try developing by inspection with the pyrocat. I just went thru a round of this and although I can see that I have to develop a few more sheets yet to make comparsions, I find it a pretty easy process right off and got good negs right out of the gate. I really don't think I'll be going back to time and temperature unless it's a daylight development. Best thing about DBI is, if you forget what you shot the film at, you can still get a good neg.

Unfortunately I am not set up for DBI. I am setup for rotary or tube development. I bought this film because someone suggested it is good for night photography. I did not have a chance to shoot night photos yet and I did not want to take the film out. So I decided to go ahead and shoot those 12 sheets in daylight. It is not film of my choice so I am not familiar with it development. I am using Efke and Fuji Acros exclusively for my shooting. I got some times as of now.Tmax100 EI 64 20C 14min ,Tri-x EI 200 20C 1:1:100 9min. I used EI 80 should I develop it for 12min?

Thanks Greg

Have you gone thru the Unblinking Eye site and read the article by Sandy King on Pyro developers. There's developing times in it for pyrocat rotary developing towards the end of the article. http://unblinkingeye.com/Articles/PCat/pcat.html

I did go trough many posts but I could not find the same film with the same EI rating and Pyro-HD as developer.Lot of people use different developers for this films.I do have probably six or seven different developers on the shelf I did not want to mix them into working solution just to use them with those 12 sheets. I am familiar with Pyro and like it a lot. I don't want to reshoot this negatives I don't want to screw them up.

Thanks again Greg

I developed negatives today: Tmax100 1:1:100 Pyro-HD 13min 20c Hand agitation negatives came out great. I don't know what the density is but it should print well.
Tri-X320 1:1:100 Pyro-HD 9min 20C Hand agitation The negatives came out good printable but there is a base fog like when I develop with PMK sort of brownish in color.
I just wanted to pass on what I found.
Thanks every one who contributed to this thread it was a great help.
