I am sure the day will come soon, but in the meantime, there is a very simple technique using Adobe Photoshop or Affinity Photo to create the illusion of a clean file. Noise is very common at high ISO or when shooting a long exposure.

Over years, I collected some 20+ Helios 44 lenses. (If you never heard of this lens, it is Russian copy of Zeiss Biotar 58/2, one of my favorite standard lenses).

Immergere la stampa, succederà che i grigi più fini passino al bianco, a vista levarla e lavarla energicamente, buttare il fix. E’ normale all’inizio accorgersi dopo che è troppo, ma nel liquido arancio non è facile capirlo. Serve per qualsiasi stampa con molti particolari quasi bianchi, spighe, prati, vecchi muri, visi sudati, da non usare per nuvole e neve perchè superfici troppo estese che verrebbero facilmente bruciate. le stampe vengono molto “fineart”. Sbianca parziale: Preparare la soluzione mescolando: ferricianuro 15 gr. / bromuro potassio 6 gr./ sodio carb. anid. 8 gr. in 1000cc (consiglio di pepararne molto meno, dura tantissimo ma se ne usa veramente poca), io solitamente faccio una bottiglia da 250cc.
