- Red Color Cast Fix
Color cast can be caused by the time of day or light filtering through objects such as red leaves. Use the adjust hue/saturation control to remove the red overcast. - Slightly Tilted Horizon Fix
Even though I doubt the waterfall is completely level, the tree on the right of the image confirms that this image is tilted. Use the straighten horizon tool to straighten the image based on the central pool of the waterfall. - Blurry Details Fix
The rocks in this image are a bit blurry. Because of the long shutter time this is likely due to camera shake. Digitally you can use levels to increase contrast and then sharpen the image to minimize the blur effect.
The Digital Editing Fix
- Red Color Cast Fix
Cathy wondered if the ND6 filter used to increase exposure time cause the red cast. The answer is yes and no. ND (neutral density) filters are purely sunglasses for your lens. They do not change color cast alone. However, because the exposure time was longer, there was more time for slight color cast in the lighting to show up on the image. Natural lighting has different casts to it at different times of day. Sunrise and sunset are generally when a red cast appears. To correct this you will need to use a color correction filter or set the white balance of your camera to compensate. - Slightly Tilted Horizon Fix
The horizon was easy to miss at the time of shooting in this case because of the many angles in the scene and it is likely the photographer was not standing on level ground. Once you spot the problem, it can easily be fixed by tilting the camera slightly when shooting. - Blurry Details Fix
A large F-Stop (small aperture) was used for this image so no more depth of field could be gained that way. The slow shutter speed is the most likely cause of the blurry rocks in this case. To correct, brace the camera securely using a tripod or beanbag brace and use a remote release.
