Io have to expose two 4x5 sheets of Hp5 + at 1200 Asa. I am thinking of Microphen or D. 76 1+1 with rotary slow process with Ilford Cibachrome motor. What development time do you recommend?

I don't have an answer but I'd like to know why you would need to expose 4x5 film at higher than it's rated iso?

Enquiring minds want to know.

Non ho una risposta, ma mi piacerebbe sapere perché dovresti esporre la pellicola 4x5 a un valore ISO superiore a quello nominale?

Le menti curiose vogliono sapere.

I'd use Microphen, as it is a speed increasing developer. Ilford reccomends about 10 min. (8min for EI800 and 11 min for EI 1600)

Natural light portrait with HP5+ @ 1600 in DD-X for 13 minutes, as per Ilford's recommended time. 120 format (RB67).

With Microphen, I would follow Ilford's recommendation and shoot at 1600 and develop for 11 minutes.

Utilizzerei Microphen, poiché è uno sviluppatore che aumenta la velocità. Ilford consiglia circa 10 minuti. (8 minuti per EI800 e 11 minuti per EI 1600)

Tomorrow I will prepare ID-68 ( Microphen). I suppose at 1200 Asa develop 9 minutes and 30 seconds it can work.
