With all the processes that need to go well when producing a print in the darkroom it is surprising that faults are not more common. Even so the odd one comes along to de-rail a good printing session. It does not matter how experienced you are sods law trips us all up!
Here are some of the most common faults:
● Chemical fingers - this where odd irregular marks appear on the finished print usually at the edges. Make sure your hands are free from chemical contamination and dry before you handle photographic paper.
● Exhausted developer - fails to produced a full image once it has reached its completion time.
● Wrongly diluted developer - produces faint grainy image. A bit like the above.
● Exhausted stop - leads to a purple tone to the white areas of the print.
● Exhausted fix - the slow brownish toning of the finished print in day light.
