This challenge is quite late due to many things but just mainly having the time available within my busy schedule to get it written and posted, for that I apologize. As a result I suggest you take the month of January to complete this challenge. There will also be a January challenge but I will wait until the end of the first week of January before I post it.
For the December challenge I encourage you to create an image using leading lines to take the viewer to your subject in your image. This is a very helpful composition guideline and with some practice it can really improve your images. Take a bit more time to view your surroundings before you start trying compositions, while thinking about possible leading lines.
First try some leading lines with a landscape image, but be sure to choose your composition to include a leading line to lead the viewer to your subject.

Let’s first start with a waterfall image, which was your November challenge, and see if you took any images that have leading lines. I bet you will find the water and the rocks in font of your water fall images reveal natural leading lines. Using this as a starting point you can now start to see and visualize where to start with your composition to make the final image stronger. Remember that depth of field is important to make sure your image is sharp from the foreground element through to the waterfall.
In the following image of the rocks on the beach I waited for the leading lines to appear using a slow shutter speed while choosing the decisive moment to push the shutter when the water came up past the rocks and then began to recede back to the ocean.
These images can be created using a shutter speed between 0.5 seconds to 2 seconds depending on the amount of water. Always remember to be careful in situations where there is potential undertow which can be dangerous not only for you but for your camera as well. In this case I was well up on the beach so there was not a lot of water, wearing rubber boots, and I had pushed my tripod legs into the sand a bit to make sure my tripod would not fall over or move from the movement of the receding water.

You never know when there might be an opportunity for creating an image, such as the ducks crossing the road in the image below. As you begin to take images in a fleeting moment be sure to also take in your surroundings and if possible move to get yourself in a position for your best composition and make use of any leading lines. Then push the shutter at the right moment to capture that special image.

With the image of Peggy’s Cove Lighthouse at sunset shown below, make use of natural occurring reflections combined with man made objects to serve as leading lines to enhance your image. With reflections it depends on the perspective, remember to move up, down, left, or right to get the refection the way you want it. Then set up your camera on your tripod to the exact position, but then wait for the sun to just start intersecting with the rocks before pushing the shutter. Choosing a small aperture to cause the star burst around the sun adds just that final element to your image, of course a beautiful sky really adds to the image as well.

Sometimes the subject of your image is not quite obvious, but is more of a concept or feeling you are trying to get the viewer to experience. In the image below of a walkway leading into a forest, it is hoped that it makes the viewer wonder what is there and that they would like to visit that place themselves, which is created by the leading line of the wooden walkway going off into the forest.

I hope that you can now see how leading lines can help make your images more impactful and how they can engage the viewer with your image, hopefully this will hold the viewers attention for a period of time longer than they normally would spend looking at an image.
Students are encouraged to develop their ability to tell a story or invoke an emotion, as well as how to plan and troubleshoot while creating their images. As such it’s important to not only create the image but to also include a “title”, and write a short paragraph about; how they came up with the idea, any interesting back ground that compelled them to make the image, and describe any techniques on how they overcame any obstacles.
As always with our monthly theme challenges we try to seek out an instructional resource, below are some YouTube video links to help with some important tips, hints and ideas.
