I recently got a Hitech 10 stop ND filter to use for some longer exposure shots. I hadn't had a chance to use it, but managed to get out today to see how it worked.
Now I have no experience of these so am unsure if I was using it correctly, but something very strange has happened with the shots and I wonder if anyone can offer an explanation?
It is the 85mm sized square filter to fit my cokin p holder. The shots were taken on my a200 with the 18-70 kit lens. Both shots were 30 seconds, 100 iso, and f/16.
The first shot was at 26mm focal length -
You can see at the bottom in the middle what look like sun flare spots? Yet the sun was off to my left and slightly behind..
This second shot was at 20mm focal length -
You can see this one has all sorts of craziness going on...
Any clue what has caused this?
Is it, light leakage? bad technique? poor copy of filter?
Or is it maybe down to the focal length being quite wide? I know the p-filter system isn't really meant to be used at the wide end, could that cause this? I wish I had of taken some shots zoomed in or something to see if this helped...
Anyway, sorry for rambling a bit, any help as always, much appreciated!
