Hi everyone,

Many thanks for your respones to my stop bath query with RA-4 at 35 degrees C. I had another go over the weekend and I am now sure the paper has aged and that this is causing the slight colour shift with the whites - easily noticed on the borders. Agree that a stop bath is essential 100%. I have ditched the paper and will be keeping my new stock in the fridge from now on!

Many thanks again,
