Underexposed

I took about 150 wedding pictures with the ISO set to low and center waited metering. As a result of this I have 150 underexposed pictures.

I have tried lighting them up many different ways including using Photo Shop and making a duplicated inverted gray scale image as suggested on DPreview. The problem is 1) that it always gives a pale look to the skin. 2) It is so slow, is there a way to do them all at once?

Hi Hugh,

is there a way you can post a couple of these images on a photo server, such as photopoint.com, zing.com or other ? I'd like to have a look. May be we can create a Photoshop droplet to automate this correction. Regards

Were these wedding photos taken in a large place such as a church? If so, then your photos would have greatly improved by using a more powerful external flash. The built-in flash has a limited range and will result in underexposure in large places.

Also, installing the newest firmware for the G1 has been known to improve internal flash exposure. Also, increasing the flash compensation might help. Or perhaps you could raise the ISO to 100 instead of 50. I guess I am assuming you are using the G1?

Hugh,
I used the Contrast Masking technique, the level curves, and a filter found at:
http://www.nikonians.c​om …ation/photo_ima​ge-mk.html

and gave your pics a try. You can find the result at http://www.zing.com/al​bum/?id=4292818781

The pics shows Before/After collated. Image have been downsized, just enough for you to see if this is ok. They're not perfect, but maybe they are better than they used to be. Let me know

Nadim, could you, please, explain or give a reference to what is "Contrast Masking Technique" ?

Andrei,

Follow this link:

and this one:

Let me know if these explanations are sufficient. The basic idea is to use the luminance of the image to adjust the contrast, using the overlay blending technique.

Just for grins, I ran one of your photos through MediaChance's DCEnhancer utility. It took a total of 8 seconds, uncluding a minor adjustment to one of the settings sliders. It's not a bad utility for a freebie...
