Benzotriazole in LPD with expired Brovira
I stumbled upon some expired, unopened Brovira Grade 3 that I plan to use it in my ordinary developer, which is LPD.
I generally use the LPD diluted 1:1.
I am wondering if I add the benzotriazole (from Photo Formulary), how much I should add — and if I need to add it at the beginning of each session or if I can add it once and re-use the LPD as normal.
On a separate note, would i have better luck using the Brovira for lith prints (is there less of a chance of a fog this way?)
