Breathing on the sensor does no harm. It's what the makers of the SensorKlear pen recommend doing with their product. The moisture (pure water) evapourates after a few seconds and leaves no residue at all - which is more than you can say for some so-called cleaning products.
"At body temperature, the exhaled breath contains air, carbon dioxide, acetone, and other gases resulting from metabolism or inhaled pollutants. The breath also contains tiny droplets of fluid containing water, bits of proteins, DNA, and cell particles shed by the airways in the lungs. When we breathe out onto a cold surface, the water vapor condenses and captures the gases and particles. The resulting fluid is called EBC, or exhaled breath condensate. It can be collected and used as a diagnostic tool much like urine or blood."
Might be fine, but it's not pure water.

sadly, I have some presets, in aperture that automattically apply a set of adjustments on import.
I hear what you guys are saying and shall endeaver to remove the word(s) photograph(y/er) from all future marketing materials.
It's only a bad photo in a rather limited and unhelpful sense.
Sorry if it seems unhelpful, what I'm trying to show is a memory.
As far as the original question is concerned, I occassionally clone out a small distraction, will always change the contrast, saturation etc (if I were shooting jpegs then I would alter these in camera before taking the shots, with perhaps a few tweaks in photoshop), sometimes create panoramic shots from several images and often use photoshop for creating posters and leaflets etc, so plenty of 'manipulation' there.
As I've said before, shoddily done photoshopping can easily ruin a picture for me. If a sky or background has been changed, it's often nearly done right, but there's a tell-tale fault which will spoil it (for me anyway). If you're going to do something like that, you need to spend a long time getting it right. My general feeling is "B*gger that for a lark!"

I'm surprised nobody's commented on the pic I uploaded, especially in comparison to Richard Day's example.

Most of the uncropped 12mm shots have been very tight interiors where even 12mm was not quite enough.

P.S. I'm surprised nobody's commented on the pic I uploaded, especially in comparison to Richard Day's example.

Enjoy the lens, when the weather / light is bad, I think about macro shots.

The lens was focused on the sign, which was about 1m away I would think. Aperture was f/8, lens was at 10mm. I'll leave you to make up your own minds about the image quality.

Personally, I feel the design is compromised as the field curvature is pretty poor and that leads to AF problems especially at the wide end. My standards for lens performance is pretty high and they didn't live up to my expectation, for some people they may be fine. Here is an example of the poor field curvature, it was taken at f8 and 10mm, see how badly the edge performance is compared to the very centre, the DOF at that focal length should be from around 1m to infinity.

I would say that my 10-20 is equal in image quality to my 16-45.
I'll have a look to see what shots I have to compare. Thinking of a view out over Edinburgh from the castle...
I've also posted examples on here before, I'll have a search for them.

P.S. Will also put in bug report for the way this deals with links seeping out of the quote box.

Face detection is autofocus that looks for, and focuses on, faces. Handy at parties and the like, when the user is too drunk to pick a focus point...

Apparently there are plenty of combinations of < and other characters that produce the same result.

(I think Dan here has used the software).
