If one corner of the frame is bright, try darkening it with a filter.
Using filters, you can control the amount of light entering your camera. This can be a great asset to use in black and white landscape photography to make the picture a bit darker or add even more contrast. For example, I put a polarizer on my camera and shoot a black and white landscape photo, the brights will become a bit darker, and this can contrast even better. Partial filters on your camera can help out as well. If one corner of the frame is bright, try darkening it with a filter. Experiment with the filter on and without it. This will allow you to see what photos will look better with a filter and which don’t. A photographer can’t succeed without some experimentation, so make it happen.
