the gnd will brighten up the bottom of the picture, if you place the horizon line properly.
this may be beneficial for pic 1 especially, because the details there are a bit murky due to uneven exposure.
frankly speaking though, because of the cloud cover here, if you use layers in photoshop, you can easily recover the details (at the cost of some noise being revealed) in the shadows at the bottom. the dynamic range here is not that wide.
for pic 3, with a strong enough GND you could possibly make the sun less burnt out.. but at the same time, because of the direct angle to the sun, you face increased chance of getting flaring, especially if your GND is not 100% clean.
Thanks night86mare,
if spore sunsets (usu lost of clounds around) are my main interest, which GND wll work best for me?
any tips on how to render the layers PP on CS4?
#3 the halo around the sun is flaring? what grade GND filter will work best for this shot ?
yes. GND is useful... if u havent got one... can use 2 overexposed, stack and mask them to produce a good exposure.
thanks Minerva,
can you elaborate a bit on "use 2 overexposed, stack and mask them to produce a good exposure" i blur-king !
