I finally got some filters!
I went out this afternoon and took some photos. I think the following were useful in helping me compare the affect of each one.
The clous were burning out in the original photo, but both filters helped bring out the detail in the clouds much better. The blue of the sky is a bit richer with the polariser compared to the ND. The red of the roofs also looks more saturated with the polariser.June 20, 2011 at 3:16 pm #20441Duncan RawlinsonKeymaster

I’ve sent you an email. Seems to be an issue with the new forum. It wouldn’t let me post attachements under my username 100258 and asked me to enter a new one, so I did! Probably a temporary glitch. Anyway, I look forward to your feedback.June 27, 2011 at 1:53 pm #20443Duncan RawlinsonKeymaster
First, sorry for the glitch. I’m not sure exactly why that happened but it may have been a phpbb caching/cookie glitch of some kind. 😳
Anyway, on with the critique. 🙂
I’m very glad that you got some filters and you’ve had a chance to play around with them.
Now for your cpl:
You’ll notice with the cpl filter several things will happen:
Better bluer skies
among other things
Cpl filters works like a grill that allow light to pass through at a very specific angle… This means it reduces scattered light and usually improves landscape photographs.
They usually only work well in direct sun. So on overcast days they really only decrease the amount of light reaching your sensor, and as such, increase the change of camera shutter due to slower shutter speeds…
CPL filters are one of the only filters you can’t fake in photoshop… So that alone is another reason to use them…
Now your ND filter.
If you’re in a situation that is white hot the ND filter can knock things way down. Also if you just want to shoot longer exposures your ND filter will come in handy.
For example to shoot this photo you would need an ND8:

Overall I’m impressed with your work in the course to date.
You are doing very well!
Sorry for the glitch in the forum…June 27, 2011 at 1:58 pm #20444ScamperParticipant
Thanks Duncan. I’ve been using the polariser a lot over the last few days and have started to understand it better. Thanks for the feedback 🙂
