One of the biggest challenges in the hide was how to deal with low light. Bears often showed up later in the evening or sometimes in the early morning (like the bear in the picture) and you still wanted to take pictures. For sharp enough pictures it is advicable to have a shutter speed of at least 1/200 sec, so that means you need higher ISO-values. Another option was to get rid of the extender and use an aperture of f/2.8 (which my new lens has). I had less mm’s, but 2 stops more light, allowing me to continue a lot longer.
This picture was taken in the morning and I decided not to go for a close up, but to zoom out a little, so I could place it more in its environment.
