Laboldtech كلوروبلاتينات الصوديوم (Na2) محلول 5% - 100مل

I was worried about mixing my own chemistry, but this solution C is remarkably consistent — the contrast control is noticeably smoother than what I got from the Iron Oxalate. My latest set of prints have cleaner highlights.

This solution C gave my platinum prints a noticeably smoother tonal range than what I was used to with the standard ferric oxalate. The 5% concentration mixed perfectly into my working developer without any fuss. I'm getting richer darks and cleaner highlights across my test prints.

Switched from the standard iron oxalate and this Solution C gives noticeably richer shadows without losing highlight detail. The 100ml bottle lasts through several printing sessions, which is nice.
