White bits for sky

In some of my non-mtb pics, the sky is all whit instead of blue.
Like these for example:


Does any body know how to conquer this problem?

i know a few ways to sort it...

1. meter from the sky as opposed to the automatic matrix metering or you metering the land. but, this means you lose brightness and detail on the land bits.

2. take down the eposure a bit

3. sometimes it just the case the sky is crappy and you just have to except that,

BUT to get the great blue skies your see pros getting you use a skylight, or even better, a polarising filter to get that cool blue thing.

Ok, thanks.
I was thinking it might be the exposure but then the land and other features would be to dark.
I have a bluey setting on my camera so ill try that sometime.

ND Grads only real way to sort it.

Cokin is cheaper but worse, Lee are more expensive but better.

They are basically bits of glass/plastic that go in front of the lens that go fade from clear to grey and so with the grey section at the top of the picture, it lets in less light so it's the equivalent of using a quicker shutter speed or smaller aperture on the sky only.

For example, I held a cokin ND grad in front of my fisheye, you can see the difference either side.

:O I heard that grad filters helped but i didn't realise that much!!!

guess im gunna have to get one when my dslr arrives, lol

It's not too simple, obviously sky can be different brightnesses in relation to the ground, so you really need a few of different tones of grey and if you go for the cokin system, you need adapter rings for whatever lense you want to use them on.

can you still run a grad filter even if you running a screw-on circ polariser?

or is that a silly idea?

cause i'm getting a circ polariser with my slr in a month and would probs like a grad filter for xmas.

Sweet! That is a HUGE difference, would i be able to use one on my nikon 3200?

I've found that adjusting the white balance helps, my camera has an automatic white balance, you basically set it up by selecting the white balance and then taking a pic of something white (peice of A4 is good) and the camera then knows what white is so adjusts colours to compensate.

Your white balance might be too high or exposure too long.
duncan_g

Yeah, ill try that too. I know i have that setting.
My mum has a slr and she also has two filters, so im gonna try and hold them infront of my camera lens and see if it makes a differnece

With the Cokin system a mount screws into the lens filter threads, so if a polariser is already there, unless it has threads then it wont work. Althernatively, Cokin make a circular polariser that fit's in the mount along with other filters like ND grads with the added benefit you can use it on any lense size between about 52 and 82mm, so long as you buy the corret adapter rings.

Then again, you could just hold the filter in front on the polariser....

Yeah like Roo said, investing in a nice filter system is worth it. You can pick them up for around 25 quid, with each filter costing about 10. I'm a fan of grad filters right now Wink
