The Truth About Pyrocat HD Stain.

Hi all,

I have been getting varying levels of greenish brown stain with Pyrocat HD. I use FP4+, HP5+ and BRF-200. BRF-200 true to pyro fame has shown the most stain but most b+F. Negs print nicely, so why am I worrying? I not to sure. Have other users been getting this stain colour? I have heard from other sources that the colour should be brown or reddish brown. I may just be red/green colour blind.

How does temperature effect staining? Does it really matter if the pre-soak is distilled or deionised - if it does surely everything should be done with distilled water? Does residual dye left after pre-soak effect stain? Is this all a bit obsessive?

One last think. Am going to start developing 5x7 in BTZS tubes. The caps don't seem to hold Sandy King's suggested developer volumn. Can concerntration be increased to compensate?

Look forward to some interesting replies.

Matt
