mostly – but not only – about film photography
I tried to switch the harddisk from 250Gb to 1Tb.
It should be an AV Disk, I choose the
Western Digital WD10EURX AV-GP 1TB interne Festplatte (8.9cm (3.5″) SATA 6 Gb/s 64mb)
The receiver will not format the disk.
Clonezilla clone did not work.
1 to 1 copy on a USB Copy Station did work.
I had to delete the Patition 4 subpartitions (5 and 6) using GParted.
Now the receiver bootet up with 930 Gb free.
Here nan interesting discussion about „fine grain“ devs:
Hi! here it is 🙂
AGFA 12 FINE-GRAIN TANK DEVELOPER
This fine-grain formula keeps well and makes an excellent tank developer
Hot Water (125 F. or 52 C)
Agfa Metol 8 grams
Agfa Sodium Sulphite, anhydrous. .. 125 grams
Agfa Sodium Carbonate, monohydrated. 5.75 grams
Agfa Potassium Bromide 2.5 grams
Water to make 1 Liter.
Do not dilute for use. Develop 8 to 12 minutes at 65 F/(18 C.).
And a comment from (I think Rüdiger):
O.K. Fine grain is due to the high content of sodium sulfite (solving developer).
Potassium Bromide seems to be a little high. This may eat quite a lot of sensitivity 1 gramm up to one stop. Modern emulsions don’t need that much – if any.
I work with a much simpler bath that Barry Thornton made for new emulsions. It is a two-bath basically
Bath A:
6.5 g metol, 80 g sodium sulfite to 1 litre.
Bath B:
20 g of sodium metaborate to 1 litre
You „charge“ the emulsion in bath A with initial inversion 1 minute, then once per minute.
Then change to bath B without watering in between.
Initial inversion only once (in order not to wash out the developer) and also once per minute.
The good thing about is: Every ISO 100 film need 4 minutes in each bath and every ISO 400 film 5 minutes.
The developer is good for 10 to 15 rolls.
Very good highlight balancing due to two-bath (developer gets exhausted in the highlights). Fine grain and sharp.You get at least box speed, if not 1/3 to 1/2 f-stop on top.
