Photoshopping U/W Pics

Since it seems to be digital photography week...

Does anyone have any tips, or is there an idiots guide anywhere to
tweaking underwater pics in photoshop (or similar)to correct colour
balance (specifically the very blue casts I got a year or two back in
the red sea when using a digital camera at anything more than 10 or so
meters down without an external strobe).

I've never really spent much time in photoshop, but when I have tried
randomly moving red and blue and green sliders about, it doesn't
really seem to achieve what I am looking for.

I did try a plug in filter (Digital ROC from memory?) which seemed to
do the right sort of thing, but I suspect that with a little bit more
knowledge, it would b possible to produce better results manually.

It's a bit of a black-art... You also suffer from the law of diminishing
returns - you can get good results quickly, but then you can end up
spending an enormous amount of time for very little return...

I don't use PhotoShop, but a tool called GIMP, but the principles are the
same. Start with the colour levels tool - just hit the "auto" button and
see what you get. There are other way to fiddle with the white balance
if there is something you know is white in the photograph, but off-hand
I'm not sure how photoshop would manage that.

Then there is contrast enhancement which is something else.

There are plenty of photoshop tutorial sites on the 'net - just search
for what you are after and I'm sure you'll find something.

Of-course, taking the perfect photo in the first place is always better
than fixing it up afterwards, but sometimes you don't have much choice!

Hi David

A bit of tweaking using colour balance and sharpen can clean up a picture. I
pinched this picture from Rob Walker's site, I'm sure he won't mind
..http://www.surfrock.co.uk/diveindex.htm

See the results here
http://www.staples-and-nails.com/Dive.htm

I don't know the first thing about web design so it might take some time to
download.

Bear in mind that this is already suffering massive deterioration by
compressing for the web but I think you'll get the idea. It's very quick and
easy.

Regards

yep.. here..

http://pt010.da-kine.info/Underwater.atn

goes in the "C:\Program Files\Adobe\Photoshop 6.0\Presets\Photoshop Actions"
folder..

the link takes out Red, but I guess you could modify it..

Try "The photoshop CS book for digital photographers" by Scott Kelby,
pub New Riders. ISBN 0-7357-1411-8

Or "Adobe photoshop CS Classroom in a book" Adobe Press. ISBN
0-321-19375-X

I've seen them in PC world, but I got my copies from Amazon. After
reading the Scott Kelby book, you'll never believe a photo again! Not
just colour changes or cut and paste, but cosmetic surgery.

I can highly recommed this book too.

first off, try auto levels. in the vast majority of cases this will fix a
multitude of sins. if that doesn't work, use a curves adjustment layer and
click auto. it'll give the same results as auto levels. you can then adjust
each individual curve (Red, Green, Blue and gamma) until you get a result
you're happy with.

depending on your camera, you could shoot in RAW then adjust the white
balance later using the cameras download software. downside to this is the
time and storage to write RAW files, coupled with the necessity of
processing each image through the software.
