Today I almost made a Becquerel dag. The polishing issues were solved by a trip to Cookson’s in the Jewellery quarter to buy a lustre polish stick – it’s great working with silver in a city that has a whole jewellery quarter full of useful stuff.
The plate sensitised over the silver surprisingly quickly – too quick for me to photograph it – turning a deep yellow with the iodine coating.
The exposure of the flyover near BOM was 20 minutes, which I think over did the plate a bit as it was sunny. Also shooting into shadows probably hindered the detail on the final plate.
I was expecting development under daylight in my red holder to be a long two hours, but the image appeared almost instantly – also suggesting over exposure.
I then decided that maybe the image would be darker when dried and impatiently decided to speed up drying using the hand drier – unlike wetplate where a hair dryer dries plates nicely, this seemed to erase the fragile image – I won’t do this again!
