Big beautiful blue skies

Working down the dock road and snapped a few against a wonderful big blue sky.
The colour and clarity of an early spring blue sky doesn't half perk my spirits up

Hi Robby, Did you use a polarizer?
Take a good look . It might not be there when you return.

Hi - No, should I have? I've not got any filters at all.

Only thing I did use was my legs as I got chased off from inside that Tate and Lyle plant by some jobsworth security guard

Not a question of whether you should have or not, it just looks as if you did! A polarizing filter has the effect of darkening blue skies and reducing haze. If you didn't use one and didn't tweak the colours in post processing then you had a cracking day!

We could do with a bit of blue sky round here at the moment as we are in the middle of the harmattan - a dry dusty wind that blows off the sahara and gets dust everywhere. Ah, perhaps I've finally found my excuse to upgrade to the K10D - dust seals

Thanks for sharing,

Great and nice colour...seems a particular clear day!
Dunno if it is bad taste to butt in on other users threads with your own pictures...if so I deeply apologize...just wanted to show you a nice blue sky obtained with my K10D and a P-FA 50mm f1.4 last weekend - no filters, no sharpening, no tweaking of colors...only post-processing was a cropping for better composition.

Lovely shots, Robbie. Ravishing colour.

Great series Robby, really like it!

With the blue of the skies it does help to expose a little bit on the low side (as you did by the (beautiful) looks of it).

There are two reasons not to use a polarizer with the 10-20mm... one is the cost of a 77mm polarizer, and the other is that the angle of view is so large.

The second problem means that there are areas of sky where the polarizer works, and other areas where it doesn't (since the polarizer only works properly at one angle, yet the amount of sky covers a huge set of different angles). This can give rise to a band of dark sky with normal sky each side, no matter what the orientation of the polarizer is.

The lens seems to bring out deep blue sky all on its own anyway - I like the pictures.

Thanks for that km - I've learnt something today
The near half moon round glass of the outer element and the filter in a vertical plane - makes sense when you think about it.

By the way km, your infrared gallery is bl**dy fantastic

you are oh, so right re polarizers on wide angle lenses.

I have problems with 28mm!
