PC-TEA times for various films

[pauldc]

Having finally got all the chemicals for PC-TEA in the UK now I have just made up my first batch. I am now excited to use it for various 35mm films I use such as FP4+, Neopan 400, Pan F+, Acros and others. For any UK people, I got TEA from www.mistralni.co.uk in Northern Ireland - great experience and fast delivery plus they also do glycol and other solvents too.

But what I have noticed is that there is not much information about times / EI's etc and especially not in a centralised or easily retrievable format such as in the Massive Development Chart. What I have also noticed is a range of conflicting views on what times to adapt - some people say times are close to xtol either 1+1 or 1+2, others says D-76. Obviously I will have to experiment to get my own personal times anyway but finding a place to start is more tricky than I anticipated.

What I also noticed was that there are no times in the APUG chemical recipe section.

So, two thoughts:

1. Can anyone help me with some starting times for any films - I use a diffusion enlarger with a colour head

2. Would it be helpful if I (or someone else for that matter) tabulated some of these times and experiences in one easy to access place for the APUG recipe section?

Many thanks!

Limited experience with this so far, but 400TX for 9 minutes at 72 degrees gives a gradient in the .5-.55 range, which I consider 'normal' for silver printing. BTW, that is at the 1:50 dilution.

My experience is similar to Clay's. Even though I use a slightly different (older) PC-TEA formula, I generally develop conventional 400-speed films for 9 min at 22C. 7' or 7.5' may be good starting points for FP4 Plus.

PC-TEA is on the massive development chart site under "Unlisted data": PC-TEA use Xtol 1+2 times.I assume this refers to the 1:50 dilution. I use the 1:100 dilution and multiply the Xtol 1+2 times by 1.6 for a first estimate.

I've been developing SBR 7/N negatives on Adox/Efke PL100 for 9 minutes, 70F (7-min 80F) using 1:100 dilution.

Thanks for the info, esp. re. TEA.
