Hi, I’ve been developing colour for a month and today encountered an issue not noticed before.

See attached images which, when you zoom in, have little white spots. They look to me like dried water spots, but I don’t know. Find below a quick info list to help narrow it down…

* Currently using Bellini C41 kit

* It’s a half-frame camera (1961 Pentacon Penti II - perhaps the smaller image makes it more noticeable?)

* For agitation, I use the twizzle stick, not invert. After several rolls either way I’ve found this the best—had some problems with inverting, much less so since using the twizzle method. I always go clockwise, then counter-clockwise, same revolutions each way. 15-30 secs per min, haven’t seen any lines or bromide drag.

*I live in a very hard water area in the UK, so use distilled water to mix all chemicals

* I forget to tap the tank sometimes after each agitation. Getting better, but still forget perhaps 1 in 2

* Temperatures are spot-on at 38C

* For B&W I always use a squeegee and have had no problems, but mixed results doing so with colour. These images were not using à squeegee.

Any thoughts and feedback greatly appreciated!

PS I lover shooting with the Penti II (recently acquired). Followed Sunny 16, set zone focusing to hyperfocal distance (2.8m to infinity), and just snapped away!

Today I developed my first colour film (slightly chuffed!).

I use lots of part film rolls, usually by cutting a part-exposed film in a dark bag, storing the unexposed bit away for another day and loading the exposed section to a reel/tank to develop that day.

For b&w I’ve always given part-developed rolls a percentage/fraction value. Eg If a kit develops, say, 12 rolls and I developed 1/2 of a roll, then I’ve still got developing left for 11.5 rolls. Never had a problem.

But just now getting into developing colour, precision (temp, timing, agitation) seems much more important. So can I continue to calculate as above, or doesn’t it work that way?

PS I’m using the Bellini C 41 Kit

Can anyone suggest a current film emulsion as close as possible to the first commercially produced rolls of colour film from the mid-1930s onwards? It’s for a project involving two cameras I have from that decade to capture as close as possible the look of that era by those who started using colour back then. Dufaycolor was one of the leaders and I like the look, but anything that closest resembles how some early colour films would have looked would work. Thx.

I’m new to colour developing at home—so far five or six rolls or part rolls (I often split them in a dark bag).

Initially some mixed results. First couple rolls/lengths were fine, but the next two or three had all sorts of issues. I was told it was development related, so I spent some time researching further and eventually tried quite gentle twizzle stick agitation.

All of a sudden I’m seeing consistency and reliability. For b&w I was quite vigorous when agitating to draw out more contrast, so does this suggest my pre-twizzle colour angitation was a little too rough?

Also, any thoughts or guidance on twizzle vs inversion generally?
