p.1 #1 · Using a GND on bottom, Reverse GND on top


Hello, I'm looking to take pictures of sunsets over water. Currently, I have a Singh Ray reverse-GND 4-stop. I'm looking to get a regular GND to go from the horizon on down into the water as I've seen some folks using this setup.

My question is how many stops then for the GND since my reverse is already 4? Thoughts?

I guess it would depend on the stop difference between the water and the upper sky. Your Singh-Ray I believe fades from 4-stop at center to about 2-stop at the top edge (or is it more or less than this gradation??). If the upper sky away from the rising/setting sun at the horizon (I'm assuming this is the type of shot you'd be using the Reverse GND for) is similar to the water in brightness then maybe a 2 stop hard grad? But wouldn't it almost be better to use another reverse as the sun will be bright on the water also right at the horizon? Or maybe you can overlap the horizon (sky/water) with the 4 stop reverse and then have the 2 stop continue on down. Only other downside is if you have land foreground in the shot then the upside down 2stop GND would make this too dark. Could you show me some photos you've seen that were taken in this way? I would think it more useful to use the reverse GND combined with a solid ND just to have a longer SS to get more misty water effect.

I like your idea of stacking with overlap, but you would use a hard or soft? I think I'm just going to have to test this one. I'm already using a 6-stop or 10-stop ND and CPL. Those are screw-on. The grads are in the Lee holder.
