Exposure with Grad filters,

[Graeme Buckland]

Could anyone help me here as I have a few of grad filters and I was wondering do you take your exposure before you place the grad filter into place? or do you take it after you have placed it down to where you want it.

Hi Graeme, I tend to get the exposure with the filter already in place, not sure if thats the correct way of photographing with filters but seems to work for me

cheers

Gut feeling says after as it is TTL metering on DSLRs. I'm going to experiment tonight as my (knockoff) Cokin filter rings arrrived and I have a Grad Tobacco filter to play with niow I can fit it to the camera.

I would have though after, if you did first surely it would be underexposed

I always do after! Get camers setup as you are will be using it, then look at settings/metering etc.

Thanks, and I ment to include this question as well, to how do you find out what size grad you will need as in 3stop 6 or 8 stop I think thats the cokin range.

i just visually judge it more than anything. The brighter the sky, the more you need. I will use an ND2 for dawn, ND4 just as sun is rising and ND8 after sun has risen. If particularly bright I will stack the ND8, with the 2 or 4 as well.
