Hi there!
Here’s another beginner’s question:
I’ve just tried out a new developer (Amaloco AM74) with Lucky 400 and Tura P 400.
The recommended agitation rhythm for this developer is as follows:
Agitate continuously for the first 30 seconds, then twice every 30 seconds
Now, my beloved 3-second rhythm has become second nature to me, so with the above recommendation I was constantly tempted to tilt just once and, ‘in my mind’, wanted to tilt again after 3 seconds.
It drove me absolutely mad.
The films took a good 5 minutes; the results were fine too.
But so that I don’t end up becoming our neighbours’ cat killer next time, I’m now wondering: how many minutes do the films need at a 3-second rhythm?
Probably less than 5 minutes.
Are there any recommendations for this sort of thing?
Develop 20% shorter, or??
Or am I completely wrong?
Can anyone help me?
Thanks in advance!
Regards

Hello Mehmet,
I assume there’s a good reason why no times are specified for the 3-second rhythm. The development times would be so short that the reproducibility of the results could no longer be guaranteed.
I reckon the time reduction would be somewhere around 30% – so you’d end up with about 3.5 minutes. At this duration, errors in the rhythm or timing have a greater impact.
Incidentally, I’m very happy with the 1-minute rhythm myself – the 3-second rhythm would drive me to go and poison pigeons in the park.

Hello,
I made a mistake there, as I was assuming a 1-minute rate. Your 20% is probably closer to the mark.

Hi CPD!
The poor things...... ;-))
But I just can’t seem to stop myself.
The AM 74 datasheet states that it is possible to use a developer ratio of 1+19 (I used 1+7). This extends the development times.
That would mean I wouldn’t get such short times.
Can I use your 30% as a basis with a clear conscience?
Thanks and
best regards

Hi again, CPD!
I wrote that before I’d finished reading it.
So 20%?
Let’s just hope it’s not a complete disaster...

Hi Mehmet,
No – I did correct myself: your twenty per cent is probably more accurate. Yes, give the higher dilution a go. But that will mean longer exposure times again, which won’t be all that different from those with the lower dilution. I’m just guessing, I haven’t done the maths.
