So, back to the Prelude Lake Nature Trail. There’s not much that I didn’t say in the last post(other than that the lake also has a beautiful beach and the water was great to cool off after the hike), so I’ll get straight into the photos. I didn’t bring all my filters on the hike, so only took a few multispectral photos.
From the viewpoint of the nature trail, the lake is clearly visible. There are several islands, and, in the distance, a few homes or cabins can be seen(although not in these photos). As it is in the Canadian Shield, the landscape is fairly flat- no mountains or valleys are visible on the horizon.
Broken into the blue, green, and red colour channels, the usual trends apply.
The trees are darker, and the sky brighter, in the blue channel, while the red and green channels are very similar. In both the green and red channels, the water is hard to distinguish from the trees. That definitely is not the case in the near infrared range.
Using my 760 nm Zomei filter, the water is pitch black, contrasting the white of the trees. The clouds are still there, but details of the cloud formations are much easier to see. The bedrock is not, however- the pink granite is indistinguishable from the foliage.
Finally, with the Schott UG11 filter(infrared and ultraviolet light), the pale trees can not only be contrasted with the lake water, but also the white of the granite. The water is not as dark as the 760 nm photo, so the details on the water’s surface can be seen.
These next two photos from the nature trail don’t have any corresponding visual spectrum photos, so there is nothing to compare them to. I just liked them. Both are taken with my Zomei 760 nm filter.
All these photos were taken with a modified Canon Rebel T3i camera.
