Hello,
The streak and bubbles in the middle of this plate, what do you think could be the cause? I don't believe it's a Hesitation mark since the plate is dipped horizontally when immersed in silver nitrate (This image on the right is a section of a vertical portrait). It might be influenced by ether or alcohol leaching into the silver nitrate, but I'm only speculating. I perform heavy maintenance and aerate the silver nitrate relatively frequently (although it might not be enough). If anyone has encountered similar issues and identified the cause, could you please share your insights? (I understand there are likely multiple factors at play.)
The collodion: KI and CdBr mixed a month ago.
Room temp: 23C
Humidity: 40%
The length of sensitization: 4mins
Thank you.
