Hi, I took a series of shots for my entry and found one that I really like. The only problem is that the setting has a lot of snow and bright sky in it, and the camera exposes the bridge darker than I'd like to accomodate. I used a neutral density +2 filter and a polarizer to try to force slower shutterspeeds. Does anyone have any suggestions as to how I can bring out more detail in the subject with the bright background without overexposing it? Also, are there any tools in photoshop that might help? I heard about increasing certain color channels (the image is desaturated btw) to bring out colors, but all I could do was change the overall tint of my image. Thanks a lot for any advice.

Hi. With the s30 you do not need filters to for a slower speed, you can :
- set an adjustment -1 or -2 and take your shot (use the button with severqal labels including WB left of the LCD. press once to get the the +/- exposure settings and move the little green rectangle to the left)
- frame the bridge, half press (it will memorize the exposure and focus) , reframe how you want it, fully press
- Use manual exposure ans select your aperture or speed
For the challenge unfortunalty I am not sure you can do anything, you can adjust the curves in photoshop ( Ctrl M) and see what you can do.
For outside the challenge, you can take too picture with different exposure and combine them in photoshop to get what you want but that's digital manipulation.
Good luck

| I agree Curves are the most powerful way to adjust the image, but use an Adjustment Layer rather than Cntl-M so the change(s) is not permanent. You can also "stack" adjustment layers to fine-tune tonal gradations. |

Exposing a photograph where you have extreme lignt and extreme dark in the same composition is not usually very easy. The neutral density filters would help tone down your highlights but, at the same time, it would darken your dark areas.
I don't know if your camera has spot or center weighted metering or not, but you may want to try that and meter the exposure on some midtone in the composition.
Snow is quite difficult to work with unless the skies are overcast and the sun is not directly on it...

Another tip is to bracket the exposure either manually or automatically, if your camera has that feature. Take three separate photos in succession. 1/3 to a full stop underexposed, properly exposed, and then 1/3 to a full stop overexposed. Than choose which of the three images to begin with in your editing.

Thanks for the advice, I forgot that my camera has exposure bracketing. I should mention I was also trying to get a flowing water effect (main reason for the filters), but even then on aperture priority, f8.0 selected and ISO 50 the shutter speed metered was 1/60 or above. Hopefully I'll have time to go back tomorrow and try to implement these changes,
