Hello, Just a quick one really I have only every used PanF+ but got my self some Delta 3200 and the film material used seems a lot darker and thicker, is this normal I scaned the negs and the came out as excepted I just thought most film bases would be almost clear.

Well I am not sure, should the negs be totally clear film base or does it have a slight tint to it
 
Ok well just looked under a glass at the neg boaders and there is grain so it is a little fogged, it was only a test film and It was my fault I remember not doing something last night to block out all the light being lazy me thinks still I will print them tonight and see what they look like

I feel I have been thinking out a loud with this one...haha
 
Sounds right given the two films you're comparing, they are like chalk & cheese and the two extremes in terms of B&W emulsion.

Any extreme speed film has a higher base fog level.

ok let me understand this, does all film have a base fog level, so it will never be clear? if thats true I didn't know that.

Yes, they do. Even the same film, in the same developer can have different base fog levels, if it's developed for more/less time. The difference might be hard to eyeball, but it's there. Dyes that are left in the emulsion after washing can make it look somewhat denser, but if you want to see what film's base looks like, put a piece of unexposed and processed film in household bleach. That will soften the emulsion, which can be removed easily. Compare it with the rest of the film to see the difference.
 
Yes all materials have a base fog level, but with most it's not visible, developers also have an effect - ID-11/D76 gives a higher base level than some others due to it's semi-physical development properties.
