Arnold’s

This is my first kallitype. It’s an iron-based alternate printing method, but unlike cyanotype and Van Dyke Brown, which use ferric ammonium citrate as their light sensitive chems, it uses ferric oxalate, which is what platinum/palladium printing uses. You can actually tone kallitypes with platinum and/or palladium and get something indistinguishable from a Pt/Pd print, but I don’t have the chems for that yet. I posted a scan of this shot back in July. Shot with a Leica R4 on Adox HR-50 at EI 400 and stand developed in Rodinal 1:100. Made into an 8x10 digital negative and placed in my UV exposure box for 6 minutes, developed in the Bostick & Sullivan “Black Developer”.
