Cokin P-type ND grads

[Twentyten]

I have,
P121L
P121M
P121S

Does anyone know the corresponding Stop values of these filters?

The reason I ask is, I want to make up labels for the boxes, and I think it would be better if I marked them+1,+2,etc.

Thanks in advance.

It should be easy to find out. Use your camera spot meter.

 

[Twentyten]

On that basis,

P121L=+1 stop
P121M=+2 stop
P121S=+3 stop

Is this correct? I may be doing it wrong:shrug:

From Cokin's website:

ND-GRAD KIT includes filter holder / Grad Grey ND2 (121L), Grad Grey ND4 (121M) and Grad Grey ND8 (121S). Code: U960

I have this set too. They are one stop (ND2), two stop (ND4) and three stop (ND8).

Thanks Steve.



How do get on with them? I don't get a colour cast using just one at a time, but if I use two together

I don't use them very often and I mainly use black and white film so I can't tell you much about colour casts!
