Can you please tell me the best way to retake this photograph.

http://images.fotopic.net/y9f556.jpg



I am under a small bridge so the light differs to whats outside so this makes the highlights in the water far to bright.

I want to keep the outline of the bridge as the frameing point.

Any suggestions please.

Does your camera have the ability to spot meter?? If so, spot meter on the water and you will prevent blown highlights. This however will cause the area under the bridge to be underexposed, requiring some selective post work to bring out the shadow detail.

Another easier method would be to take this pic on a cloudy/overcast day, where you have no direct sun and the two 2 areas (under the bridge and the waterfall) will be chave similar exposure requirements.

Lack of dynamic range is the root problem. The only solution I know of is to use multiple exposures. See http://luminous-landscape.com/tutori...xposures.shtml

Some cameras have exposure compensation.

You could use exposure compensation to get the right exposure on the most highlighted part of your picture.

I agree with BillDrew, you are at a loss for dyanmic range.

Another way to build a higher dynamic range image is to use the new "merge to HDR" function in PS CS2 http://www.luminous-landscape.com/tutorials/hdr.shtml

This function will take 2 or more images, taken at different exposures (use same F stop for all) and merge them in to one 32bit/channel HighDynamicRange image.

Also use of a tripod is a must, all the images must be in register.

The function will work with 8bit jpg as input, but 16bit RAW files are pereferable.

That's a pretty good pic, bro'... Except for the waterfall.
Yeah, I agee with the others that your only good option is to reshoot the scene without blowing the water.
If you can't do that -- like the scene was taken 2000 miles away on a vacation -- you possibly could select the blown water and use the color picker tool to sample the color of the "good" water and fill the selection with that color. To add a bit of charactor you might then clone some of the texture from the "good" water into the waterfall and then use something like the motion blur tool to stretch the cloned texture out to mimic downward water flow.
Admittedly, this stuff is kind of Rube Goldburg, but only you can decide how much effort you want to put into "fixing" the problem.

the best way to retake would be to exposure compensate

Again thanks for the input.

Do you know what? That shot has some serious potential and I personally would keep trying until I got it spot on. It would look great as a greetings card for example.

I agree with Bill. I would approach this with a merge of 2 shots. Try getting the outside right first and worry about the inside later. It is easy to pull and enhance detail from dark areas but when you have blown out highlights, forget it!

Use a tripod, stay dead still in between shots and take one shot exposed for the waterfall, another for the interior and blend them.

I hope you don´t mind my playing with your pic but this took less than a minute to get your picture to this stage, so I don´t think you are far off.

When you get it right, please post the image for us to see.

Nice shot!

Nick

Give photomatrix a whirl http://www.hdrsoft.com/
it will combine many exposures into one HDR(High Dynamic Range) file.

The downloadable demo will give you a good idea of what is possible.

Yes use of a tripod is a must, as is a fixed aperture for the input exposures.
Vary only your shutter speed:!:
