Default Please, why is sky washed out?

Hi everyone!

Why is the sky washed out while my wife with a point and shoot gets blue
skys?
It seems to me the sky was quite blue when I took this photo:

Any ideas? Recommendations?

Thanks,

Marcel

set it? If you're just beginning start with auto WB of set the proper
preset for the scene at hand, such as sunny for this scene.


But did you look at the linked jpeg? The sky is just overexposed.

The sky is over-exposed; basically, it's so bright that the camera
sensor is saturating and just sees it as "white". You needed to tell the
camera to take in less light, either by using a faster shutter speed or
by stopping down the lens. Depending on the features your camera has,
there are a variety of ways of doing that.

Sorry Daniel, I forgot to say. I have a Canon Rebel XT and the lens I used
was a Canon EF-S 17-85mm 1 4.5-5.6 IS USM

OK, so you have a camera with a full set of manual controls. A few
options:

When you meter, meter on the sky rather than the house. This will
convince the camera to take in less light.
Meter on the house, but dial in a negative exposure compensation.
Go into full manual mode, and set the aperture/shutter yourself
Switch from JPG mode to RAW mode; there may be useful data in the RAW
file that got lost when the camera converted to JPG.

The camera is exposing based on the dark tree in the center of the pic.
In those situations you should either dial in some exposure
compensation ( -1 would be a good starting point) or else simply go
into manual mode and expose manually.

And of course, if you shoot in RAW mode you might be able to recover
most of the blown out highlights.

This is impossible to fix in photoshop (except by copying a sky from
elsewhere), because the sky is just a solid area of 240 240 240.
Obviously, there is not enough information there to do anything. If this
had been shot in RAW, maybe it could have been saved, and maybe not.


I am "old school" so take my advice accordingly. If you are taking
lots of pictures like that and want the sky to look better, keep the
sky from overexposing in the first place and everything after that is
much easier. The way to do that is to invest in a polarizing filter.
That will allow you to darken a sky like that (plus keep interesting
details in it) without underexposing the rest of the image. It will
also cut out most glare that you encounter.


Indeed, a polariser is a good solution, not just to prevent overexposure
but to give more saturated skies etc. I don't see how this is old
school, though.

For an autofocus lens, you want a "circular polarizer" (don't ask why,
it's a long story, you just want one).

People in this group hate filters and they hate people who don't shoot
in RAW, but really, a filter is the answer. That's the way we did it
back in "the day" when we used that stuff called film.

Good luck with it.

Pat

I'd have to disagree. Open it up in an editor, and look at the sky. It's
a solid block of RGB 240,240,240. White-balance issues might give a
screwed up color, but there'd be _some_ variation across the image.

single use cameras use a fast shutter speed and ISO400 film.
that P&S might also were using a faster shutter speed than you set
your SLR. set to exp.comp. -1 and the sky will be blue.
thats what I did when taking a photo thru a tree stump into the sky.
