Halation during stand development

[Trask]

I've occasionally had what appears to be halation appear around the brightest highlights when I've used stand development -- last night, example, I ran some Foma 100 rated at ISO 100 in Rodinal 1:100 50 minutes one agitation at 25 minutes. The negatives are nice and sharp, grain effectively absent, but around one woman's white blouse photographed under direct sun I get a kind of "glow" that I wish weren't there.

I'm thinking that I should cut back my development time to see if I can retain the qualities of stand development (using Rodinal or other developer) while losing the glow.

Has anyone else had this happen, and what have you done to avoid this problem?

Different films have varying degrees of halation suppressing layers, Foma has less a weak anti halation suppressant, Chinese Lucky film seem to have none at all! Other films like Kodak/Ilford seem better in this respect.
I'm doubting stand development is the culprit in this case..

Fomapan 100 has rather poor anti-halation characteristics in 35mm. If you used this format I would say that this is the reason – not an artefact of development.

Since Mark beat me to it – does the halation you encountered look something like this: (there was a url link here which no longer exists)

Uhner: i'd say that what I'm seeing it a bit more pronounced. I don't know if it comes across in the shot I'm attaching, but the woman's blouse has a sort of ghost bloom around it. Other shots that don't have such a bright highlight don't exhibit any bloom - what I consider halation - so I do think it's related not just to the exposure, but to a combination of the extended development and poor anti-halation. I'll repeat my test with another type of film to verify.

I actually think that 'glow' looks pretty cool.
