if you like you can clip a little bit off the start of the roll and

guess a time . all you will do though is increase the contrast. try

about five times longer than usual.

try rating 400 speed at 200 and process normal, 100 at 50 etc. most

b &w film appreciates over exposure a little.

just try all different ways to come up with somthing that noone else

know about.

I am having problems with gritty negatives. The water that I use to mix my chemicals and wash my negatives is of poor quality. It is quite dirty and increases in colour with heavy rainfall.

I'm just thinking about any cheap, fast, effective methods of filtering my water for the darkroom. On a low budget, I'd like to find the easy way out before expensive filtration renovations.

Thanks in advance for any help

This is my second day using the forum.

I've been looking for information on enlarger aperture. What are the reosons and effects of using differnt apertures in the enlarging process apart from speeding up or slowing down the required exposure time.

Is it best to feel it out myself?

How is depth of field effected here?

Thankyou,

I'm using a medium format capable enlarger for my 35mm B&W printing. It is quite old and has a lot of dust all over.

My prints are coming out with hairs and dust particle images on them now.

What is the most effective way of cleaning the delicate glass surfaces, etc.

There is dust all through the focusing bellows. I tried to give it a clean , but to no avail.....
