Processed print faults

Exhausted Developer

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!

Exhausred stop

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.

Exhausted Fix

●         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.

Over development

The film has been processed for longer than it needed. The following can cause this:

• Too long a development time.
• Too high a temperture. ( thermometers can go wrong.)
• Too much agitation.

Attention to these factors should avoid this. If you know that a film has been under exposed then you can remmedy it by over developing.
