anyone using split neutral density filters for landscape shots. Ive been thinking of getting one to try on my panny 20mm. I can get a 46mm stepup filter to 52 then by a cokin adapter....any thoughts on this...and thanks very much.
i want a neutral density filter in the software of my digital camera,
if the computers in these machines can recognise sylvester the cat and expose and focus for his cheshire grin, , then surely it can use an algothrim that can identify a sky\ foreground perimeter and give me a few stops of different exposure ala digital nd filter
and give me a decently exposed foreground without a blown out sky
I have a selection of Cokin P series Graduated Neutral Grey filters that I originally bought to use with my dSLR. When I moved to the G1 I just purchased the 52mm adaptor ring. Now also the owner of a GF1 I purchased the 46mm to 52mm stepup ring. I know some say you can achieve the same end result in image editing but I disagree. The m4/3rds sensor is prone to burning out highlights and you cannot rescue these with editing. With landscape shooting and the huge dynamic range difference between sky and ground I find these filters very useful.
I have a Lee RF75 filter set with the rings, polarizer, ND filters, and hard and soft grads. It's an excellent system but $$$. I bought mine from Robert White in England for 2/3 of what it would cost here in Canada. Maximum lens size is 67mm - perfect with u4/3.
