Capturing Objects in Fog

Hello. I have a Canon PowerShot A620 and would like to know what
settings can 1) capture actual fog/rain while 2) choosing one central
subject and making it clear (as though the fog either weren't there).
Every setting I tried this AM in the PA mountains kept both the subject
and fog...foggy.

Thanks.

You don't. If the fog makes the object appear unclear, there is no way
of changing that. You need to pick a time, and location where it is the way
you like.

Now you may or may not find that careful use of a polarizing filter may
help you out.

Dear All, this might be useful for you and your family

Technically engineered natural minerals have been structurally bonded
in glass, at molecular level, using several high heat fusion methods.
This combination of the techniques causes a catalytic energy conversion
creating a long lasting, specific natural Nano resonance in the BIO
DISC.

Transferring the "Nano Energising Frequency" into or through liquid
affects the nanos within the liquid. When the mineral nanos come into
contact
with their specific frequency they behave completely differ ently from
the host atom for instance: they boil quicker, are lighter and refract
more light.
This natural resonance has the ability to create a molecular structure
in all manufactured or treated liquid and vegetation.

Product benefits:
-It will enhance taste of food and beverages
-It helps to improve sleep
-It has the ability to balance ying and yang and create a CHI Life
force
-It helps to create energized water by placing drinking water on top of
it
-By drinking the energized water created from Bio Disc will help you
detoxify
and hydrate all body cells
-It enhance your immune system of the body
-It reduces stress levels
-It increased take up of nutrients
-It increases oxygenation of the blood
-It has calming effects of the resonance increases mental Cognition
-Rejuvenating molecular structures and nano cells, reduces bacteria
formation,
extends shelf life, improves taste and slows down the aging process.
-Fruit, vegetables and meat lose molecular structure as they age.
All can be revitalised at a molecular level by Qi technology
resonance.
-Put it in the pocket to reduce Jet Lag
-Improve Wine Taste
-Pour cosmetics/lotions on the surface of BIO DISC to maximize the
benefits of cosmetics/lotions
-Place BIO DISC on any wound/injury to accelerate the healing process
-Move it counter clock wise to remove muscle injury
-Remove Fat From Milk
-Put cigarettes box on BIO DISC for 30 minutes to remove Tar and
Nicotine from cigarettes
-It accelerates relaxation into deeper meditation

NO SIDE EFFECTS AT ALL

If you pull your foggy image into an image editor, you can adjust the
contrast to pull the subject forward to some degree.

If you have Photoshop, convert to Lab and adjust the L curve. Lab seems
designed for fog and haze.

You have part of what you want already, since the fog is foggy.
Distant mountains (if they're included in the shot) will remain
foggy. To minimize the effect of fog and rain on the subject, you
should try to reduce the amount of fog and rain between the camera
and the subject, at least in relation to the amount in the rest of
the picture. To do this, zoom the camera's lens to its widest angle
and get much closer to the subject. If you've ever seen a televised
football or baseball game played in moderate rain, very long
telephoto shots make it appear as if the game is being played in a
downpour, while simultaneous closer shots of players, referees and
umpires often display little or no evidence of any rain at all. If
you're handy with photo editors, you might be able to make a good
composite, with an early, foggy AM shot and a later shot when most
of the fog will have burned off or dissipated.

You can try to maximize contrast, if that adjustment is available on your
camera. However, if you have PS elements or another editor with layers and
unsharp mask available, try this method to improve local contrast:
Create a duplicate layer
Set USM filter to r=50, strength=50% and threshold =0
Apply to the duplicate layer
Now adjust the transparency of the duplicate layer until the histogram for
the complete photo shows a minimal amount of clipping in the shadows and/or
the highights. Usually, 40% - 60% transparency will work.
You can experiment with other duplicate layer blend modes as well:
If you have a lot of shadow detail, setting the blend mode to lighter may be
better.
If it's a high key photo, try setting the blend mode to darker.
If it's extremely low contrast, Try multiply or overlay.
Have Fun!

You can't create detail that isn't there to work with.
If your sensor recoreds only fog...it isn't magically able to see through
it.

**If it is only light fog, or haze, however, you can definitely reduce its
visibility--even with a simple levels adjustment. As you increase contrast
in this way, you'll end up losing some shadow detail, but you can cut
through smoke, light fog and haze quite a bit.

Can you post the image somewhere? It's hard to know whether you're asking
the impossible without seeing the image to which you refer...

Definitely. But don't let that be an excuse to stop using Beano.
