Wash time

[cxc]

What is accomplished by the long wash time at the end of the film

processing cycle? What are the risks in shortening the time?

5-10 minutes max. Use Perma-Wash or a similar product.

The wash removes all the fixer from the emulsion. It also removes the hypo clearing agent, if you use one. There are many different opinions on how long a wash should be, but if it isn't long enough, fixer and HCL may remain in the emulsion and shorten the life of the image.

The wash time depends very much on the flow of water - the difference in required wash times will be several minutes based on how well the film is washed.

[titrisol]

if you're using a tank try filling it with water, agitate for about 30 secs empty

repeat 3 to 5 times

then use distilled water and do 2 rinses

 

done

 

shouldn;t take over 10 minutes and you use 9*500 ml = 4500 ml (1.4 gallons)

You'll need a longer wash if your fixer is near the end of its life: Using a two stage fix will shorten up your wash time.

A couple days ago I posted an article entitled <i>Why two step fixing is a Really Good Thing</i> <a href = "http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=007dXZ" target = "_blank">at this link</a> which gives you more detail than you can digest(!)
