Shadows in the sky?

I own a G12 and shadowy blobs appear in the sky when I shot pics on sunny days with the sun BEHIND me. I have noticed a small scratch on the lens which could correspond to the area; is that the cause? as yet it doesn't sem to affect pics whn I shoot into the light, like at sunset. I'm gonna try some flash indoors to see if it produces any unusal artifacts. Has anyone else suffered from this. Heres an example

and this full size close up

thanks

That looks a lot like a dust spot on the sensor, although your supposition of a lens scratch could be correct.

In LIghtroom it is quite easy to take dust spots out of the image and I believe there may also be a way of mapping the spots and taking them automatically out of the image, but I am unsure of that.

Or, you could send it to a service depot.

I recognise that view Malvern Hills in Worcestershire I live close by. Yes very likely as you have a scratch to be that. Does look like a dust spot mind on sensor. Take a photo of a bright white piece of paper and see what that reveals.

Re: Shadows in the sky?

Sensor dust tends to be small, the size of smudge points to lens surface. Below was from my little Ixus a few years ago, in that case able to clean off the lens:

Post processing works well, but would be irritating if a permanent problem.

Just use a little fill flash. You might have to zoom in the flash head all the way.

Good idea: but nothing showed up! Even when I turned up the contrast.

These shadows only seem to happen on sunny days with the sun behind me and always in the sky.

Does anyone have another idea whats going on here? I have a sensor spot on another camera and it replicates in the same place in every photo. I thought the scratch might be the cause but nothing shows up when I shoot into the sun at sunset for example.

thanks

Sensor dust

This looks exactly like the 'shadow blobs' I would get on my P200 back in the day.   Usually only showed up in sunny, high contrasty pics.  
Back then there was a vacuum cleaner trick that sometimes worked to remove them.
Good Luck
