Thanks for helping me with this image Dave & Dave!
(Gee, we’ve got almost as many Daves around here as we do Jims.)
As a neophyte, observing how more experienced and capable photographers handle an image is a great learning tool.
Besides the overcast skies and fog present in the shot, I think it was probably at least 1 f/stop under exposed. That all conspired to rob the shot of color, sharpness, and detail. It looks like both daveman and dave_lines adjusted the color curves, increased the color saturation, and sharpened the image. All of which improved the shot dramatically. dave_lines’ tighter crop offers a completely different perspective, but points out that shooting from higher up would have been a better perspective. The crop leaves me wanting to see the rest of the lighthouse.
After seeing what you guys did with it, I went back and took a couple more tries. The biggest difference between Versions 2 & 4 is the amount of color saturation added and a slightly tighter crop in Version 4. I was surprised to see that increasing the saturation past a certain point seems to negatively affect the perceived sharpness (?).

Thanks!
