A shot of the Talbot Valley in Guernsey.


I'd like some general thoughts on exposure and what the 'marks' in the sky my be. It's Adox CMS20 I, exposed at 12ASA developed in Adotech II for 8.5 mins at 20 degrees. The shot was about 15 seconds so the marks in the sky could be cloud movement but I think they look more like some sort of chemical problem?

Sorry to hear about your processing woes Tim.


On my computer, It's not too easy to make out.
Could it simply be extended movement of the leaves and branches in the wind (optimistic)?


If not, them I suspect it could be a touch of the dreaded "bromide drag".


Look it up on the web (& pictures too) to try and confirm if you negatives suffer the same symptoms.


I believe it's generally considered to be a processing issue caused by one or a combination of factors such as agitation, dilution, volume etc. And reveals itself randomly as bands or a mottled effect in even-toned areas especially like skies!


Do get back to us with your findings and if necessary a thorough analysis of your processing regime.

Hi MartyNL


Thanks for the pointer on Bromide drag, I'll look it up. I know this film & developer are notoriously unforgiving, so it's probably my laisse-faire developing technique. I think this was the 5th film I've developed in about 15 years.


It is difficult to make out on the scan, it's on another neg at the beach location I went to after the valley so I guess it's chemical.


The scan of the print takes out quite a bit of the depth of tone that this not great print has.

Hello Tim,


Yes, I've been flicking through the data sheets and you've really jumped in the deep end with this choice.


Having said that, exposures look good and you've done a successful job of taming the contrast. So not a bad start after all!


If this is going to be your standard combination then your technique (development especially) will have to become meticulous.


Unforgiving... MERCILESS me thinks!
